1 Overview

1.1 Product Introduction

1.1.1 IntroductionPredictive and preventive machine maintenance have become indispensable parts ofIndustry 4.0. Machine condition monitoring (MCM) systems upgrade consumablesand replace damaged parts, as well as perform periodic maintenance activities, initi-ate preventive maintenance, and even permit predictive maintenance. This preventssituations in which machines are halted without warning which causes unwantedoverheads.

Machine Condition Monitoring

To enable preventive machine maintenance, a series of processes and analysesmust be carried out so that converted collected sensor data contains useful informa-tion that predicts the health condition of machines and crucial elements. Sensor gen-erated signals undergo the following process in the machine condition monitoring(MCM) system:

Data Acquisition: Defines the data acquisition triggering conditions, number of chan-nels, amplification, sampling rate, and conversion of physical variables. These con-figuration parameters will be written into data acquisition modules.

Time Domain Preprocessing: Processes the captured raw data and optimizes signalqualities, making the algorithm more accurate.

Frequency Domain Preprocessing: An optional processing step that converts timedomain data to frequency domain data for fine optimization of signal qualities.

Feature Value Extraction: Calculates processed data with the selected algorithm andextracts feature information, which already has meaning (e.g. the RMS values duringa certain period, or energy magnitude and frequency of vibration), from a large seg-ment of continuous time domain or frequency domain data.

Interpretation: Interprets extracted feature information and makes decisions.

Output and Communication: Sends out feature and decision messages using net-work communication protocols or digital/analog signals to connect with control con-sole or other control modules.

Please refer to the specific process below:

MCM creates a configuration page for each processing procedure, acquires real-timedata, displays the results of each configuration, and eventually guides the user toimplement a configured application.

MCM User Manual 2

Chapter 1

Overview

1.1.2 WebAccess/MCM (Machine Condition Monitoring)WebAccess/MCM is a Machine Condition Monitoring software that extracts usefuldata after massive data computing, which enables machine condition visualization,controls crucial element lifetimes, analyzes and optimizes production lines via mas-sive data recording, and reduces downtime while maximizing machine productionbenefits, which at the same time reduces machine maintenance cost and enhancesmachine safety.

Apart for predictive and preventive maintenance, MCM is also suitable for measuringproducts of the product line, especially in measuring time related serial signals suchas vibration, sound, discharging and waveforms. MCM features various built-in func-tions, including waveform processing, time frequency conversion and feature valueextraction, defines data processing procedures as configured, captures and analyzesdata at real-time, sends out checking results by way of standard communication orsignals, and integrates the results into the whole SCADA system. It complements thedefects of systems (e.g. SCADA) which are unable to handle high-speed continuouswave forms.

In the MCM system architecture, every data acquisition module is independent,which ensures safely that every module can be restarted by the system. Highly inde-pendent functions and modules can be added without backtracking modifications. Itis highly flexible so that the same architecture is suitable for both centralized and dis-tributed structures. Meanwhile, the server can retrieve the data and processing onthe edge, as well as build the architecture which is the same as that on the edge. Thesoftware can be flexibly integrated with the Client/Server or P2P.

WebAccess/MCM supports three kinds of application modes:

Measurement Analysis: Helps the user to analyze signals by simulating the oscilloscope. It provides simulated oscilloscope functions, including cursor mea-surement tools, panning and zooming, and triggering and retrieving functions, which enable easy interpretation of vital information. Automatically measures the amplitude values, average values, peak-to-peak values and frequency, and displays time domain data, spectrum data, and other related feature values.

Intelligent Inspection: Enables the user to capture signals after parameter con-figuration is completed via UI page, implements condition interpretation for cal-culated results (e.g. average voltage value and RMS value), filters defectives by setting high and low limits for interpretation, uploads measurement results and generates quality inspection reports for automated inspection systems.

Machine Condition Monitoring: Monitors machines, converts a large amount of data into a single piece of useful information via real-time calculation, and pro-vides various data preprocessing algorithms, such as Crest factor, Kurtosis, Skewness, Harmonic, Shape Factor, Impulse Factor and Clearance Factor. Meanwhile, it provides customized feature algorithms and transmits data to the cloud via EtherNet communication protocol for on-line device condition monitor-ing, data analysis, and machine learning.

The application modes above are implemented by the following functions in WebAc-cess/MCM:

No Coding Required: All configurations are completed on UI pages without any soft-ware programming. This helps cut down investment in development resources andaccelerates new project implementation.

Spectrum Analysis: Displays real-time domain and frequency domain analysischarts of data as well as calculated feature values. Assists analysis by providinganalysis tools, and enables the user to figure out the key features on the machine inthe modeling stage more quickly.

User and Device ID Verification: The built-in ID verification function of the softwarecan limit the account with which the user can view and change system data andparameters according to different permissions.

Data Pre-processing: This function enables signal optimization and features timedomain pre-processing, including moving average, weighted moving average andFIR filter that supports common filter types such as high-pass, low-pass, band-passand band-stop. In frequency domain, its functions include filtering as well as filteringdirect current.

Feature Extraction: Core technology that provides a large number of algorithms.Because there is a huge amount of dynamic signal data collected by the card, dataprocessing must be completed at the edge, and only the calculated results or keyfeature values should be uploaded. This function provides various feature algorithms,including Max, Mean, Median, Min, RMS, Pulse Width, Pulse frequency, Time ofMax/Min, FFT frequency, Crest factor, Kurtosis, Skewness, Harmonic, Shape Factor,Impulse Factor and Clearance Factor, which will continue to increase.

Interpretation and Output: Provides simple configuration for mathematics, bitwiseand logic operation of feature values, and performs interpretation and output accord-ing to the operation result. This function enables the user to monitor device healthstatus via the comparison between upper and lower limits, and can output communi-cation or hardware signals for notification or emergency action.

Data Storage: A large amount of raw data or feature values can be stored locally fordata searching, comparing and displaying.

Support for Synchronous Operation of Remote and Local Terminals: If MCM isinstalled on multiple devices, the same data and computing analysis will be availablefor both remote and local terminals. The operation status at the edge could also bechecked remotely.

Upload to the Cloud: Uploads data to the cloud via EtherNet communication proto-cols, such as Modbus and MQTT.

There are three programs in MCM: Viewer, WOGenerator and Worker (WOGenera-tor and Worker are collectively referred to as Catcher). Viewer, the core of the entireMCM, is responsible for configuration including project management, card parameterconfiguration, time domain pre-processing, frequency pre-processing, feature valueextraction, interpretation and output, which will be introduced later. Meanwhile, theuser can search for the edge device, search for the device existing in the same net-work via LAN, or configure related settings by entering the IP directly. What's more,Viewer supports user management, operation management and operation display-ing.

Catcher aims at acquiring feature values remotely and storing according to a user-defined storage strategy, including file formats and field formats as user-specified file.In this way, the user can collect data from different edge devices, combine data fromdifferent sources, transfer data and re-arrange time scales, storing data in standardfile formats. First, the user has to define the feature and file storage strategy withWOGenerator in order to generate a work order file.

Next, load a work order file with Worker to acquire the feature and save it as a file.

1.2 Installation Conditions and User Guide

1.2.1 Installation SuggestionsMCM provides an installation package for deploying the Server, the Viewer and thedata capturing and transferring terminal. The user can choose the package accordingto actual deployment requirements. This Waveform Factory Framework deploys andinstalls files required by MCM Server on your slave machine system. The CMS mod-ule deploys files required by MCM Viewer on your master system. The Viewer ismainly used to operate, configure and manage the slave machine and slave machinedevices. The Catcher module contains two tools: WO Generator and Worker. Gener-ator configures channel information, feature information and the format to be stored,while the Worker stores data and transfers data to the cloud. For data storage, it'srecommended to install the Catcher on the master machine system, because it canmanage, integrate and store the information of multiple slave machines. For transfer-ring data to the cloud, it's recommended to install the Catcher on a slave device, sothe Worker can send data to the cloud via MQTT. This installation package is alsosuitable for Windows systems of Windows 7 and Window 10 32/64 bit.

Please choose the module according to your deployment requirements. The user canalso install installation packages of the Framework, the Client and the Catcher on thesame machine.

All of the data acquisition devices of the current slave machine can be automatically enumerated on the Device Configure list. Users can choose and switch devices for specific requests, and set basic property parameters for acquisition. You can select Polling or Event on Data define page. Polling can be used for discrete data acquisition by analog input or digital input, with Settings as configuration parameters correspondingly. On Pushed tag, Events can be chosen as the triggering condition of the acquisition, with functions such as Interrupt, Status Change and Pattern Match being the judgments. Once the con-ditions are met, discrete data will be acquired. The Calculator mentioned here is the same as the Calculator introduced later. It can calculate subscribed discrete data or feature value, or take these data as the index to directly implements data transmission, input condition or controlling operations. External signals can be used for Processing to control start or end condition, while the index of Calcula-tor can be used as the control condition of start and stop. However, the user should confirm if the control can be actually enabled while the conditions are met, or else no data will be collected. Please refer to subsequent chapters for details.After the input configuration is finished, click ">>" at the bottom right to jump to the Waveform Acquisition page.

5. Time Domain Pre-process: This page shows the configurations for selecting the built-in time domain pre-processing algorithm in MCM for the specified channel and configure the corresponding parameters. Results of data processing will be displayed in the area of Display After Time Domain Preprocessing in real-time. You can directly view the original signal collected by the current channel and the results processed by time domain pre-processing algorithm. Here, MCM pro-vides moving average and weighted moving average, and the FIR filter, which supports common filtering types (high-pass, low-pass, band-pass and band-stop), utilizes the Butterworth parameter that is popular in the industry and sup-ports settings ordered by the parameter. Comparing to frequency domain filter-ing, time domain filtering can rapidly filter noises from signals because of its special calculation method. You could choose the filter and modify the parame-ters according to your request, and do a quick comparison of processed results.The measurement channels of the current device will be listed below the win-dow interface. The user can select the channel and choose the pre-processing algorithm to be added in Preprocessing Method box on the right. After the selec-tion, click "One shot" or "Free run" to gain data.After the time domain pre-processing configuration is finished, click the ">>" symbol at the bottom right to jump to the Frequency Domain Pre-processing page.

11 MCM User Manual

6. Frequency Domain Pre-processing: After the original signal is processed in the time domain, it will be processed in the frequency domain. MCM will automati-cally select FFT or DFT according to acquisition configurations, and convert time domain signals to frequency signals. For frequency domain pre-process-ing, MCM supports filtering including low-pass, high-pass, band-pass and band-stop types. Apart from filtering, it also supports Remove DC offset and window-ing processing with the window function Hann Window, 4-term Blackman-Harris Window and 7-term Blackman-Harris Window. These functions can be added in the box of the channel selection below the window. If you've chosen Remove DC or windowing processing, the display area of the frequency domain pre-pro-cessing will show the real-time signal processed in the time domain, or the dis-tribution of frequency and energy transferred to frequency domain via FFT/DFT after Remove DC. If you've selected filtering during frequency domain pre-pro-cessing, you can directly view the results after filtering.The measurement channels of the current device will be listed below the win-dow interface. The user can select the channel and choose the pre-processing algorithm to be added in Preprocessing Method box on the right. After the selec-tion, click "One shot" or "Free run" to gain data.After the frequency domain pre-processing configuration is finished, click the ">>" symbol at the bottom right to jump to the Feature Extraction page.

8. Calculator: In real application scenarios of measurement and control configura-tion, sometimes it's necessary to do condition judgment for signal's feature or to define complicated expressions, so that when the conditions of a certain feature of the signal is met, the corresponding decision should be made, e.g. the corre-sponding processing will be enabled when the average is larger than a certain condition value. This is exactly the usage of this page. On this page, the selected feature value is used as the variable to generate Condition index expressions with built-in mathematics operator, comparison operator, logical operator and built-in functions. Please refer to Appendix A. for detail information for available formula and operators.After the Calculator configuration is finished, click the ">>" symbol at the bottom right to jump to the Output page.

9. Output: MCM provides two types of output, which include Modbus and AO/DO. DAQNavi or Modbus can be selected according to the Transport type. Output provided by MCM supports Modbus protocol that you can output the results of the Index defined on the Calculator page through Modbus protocol. Since it sup-ports Modbus address settings, you should manually input the value type range.For AO/DO output of DAQNavi, the Index's results of Logic type will be output by acquisition boards with AO/DO capability. MCM will do automatic inspection and list available AO and DO channels on the Advantech acquisition board in the slave machine.You can choose a channel as the output channel of the Index, e.g. if the Index is set to true, it corresponds to DO output, or when the Index is set to "True", a voltage value will be output via AO channel.

2.6 Introduction of Pre-processing and Algorithm

2.6.1 Time Domain Pre-processingTime domain pre-processing will collect original data streams from the acquisitionmodule and differentiate them as Scale Data for each channel. Currently, there arebuilt-in pre-processing algorithms for the user to select. The page and configurationmethod are as follows:

1. The plugin selection is not available yet, and the user can use the self-made time domain pre-processing algorithm as a plugin to load the MCM.

2. The channel list is the collection of channels checked on the acquisition UI.3. For algorithm collection, the default is None, that is, no algorithm processing is

performed. Click the drop-down list of pre-processing algorithms to select the required algorithm item, the required configuration parameters of which will be automatically listed in the field.When using, you have to select the channel first, and then select the pre-pro-cessing algorithm for the channel.

2.6.2 FFT and DFTIn real application scenarios, the frequency distribution and the energy level can't bevisually recognized, but the signal analysis depends on frequency characteristics, soit is very important to process the signal. Therefore, the time domain signal is con-verted into the frequency domain by Fast Fourier Transform (FFT) or DFT (DiscreteFourier Transform (DFT) operation, and the information hidden in the time domainwaveform can be observed and found.

The MCM determines the algorithm (FFT or DFT&FFT) of conversion from timedomain to frequency domain by the current acquisition parameter status, and showsthe energy spectrum distribution map.

When switching from the time domain pre-processing page to the frequency domainpre-processing page, the energy spectrum distribution map, which demonstrates theresults of the FFT/DFT operation for the currently acquired signal, will be shown onthe Graph of the display area, wherein the abscissa is the frequency, the ordinate isthe power spectrum, and the unit is db.

27 MCM User Manual

2.6.3 Frequency Domain Pre-processingAfter FFT or DFT operation, the signal processed by the time domain preprocessingalgorithm enters the frequency domain preprocessing stage. The following is the fre-quency domain preprocessing page interface:

1. Signal, Windowing and Remove DC options: Determines whether to perform a window operation on the current channel. If a window function is selected, then the result of FFT/DFT operation after windowing the signal of the channel that has been processed by the time domain pre-processing algorithm will be shown in the display area. Therefore, please notice the windowing process time domain signals. This option is on the frequency domain pre-processing page because of its special characteristics.

2. Algorithm and parameter configuration of frequency domain pre-processing: Currently frequency filtering is supported. The filter type can be selected from Low Pass, High Pass, Band Pass and Band Stop. The default type is High Pass.

Intro

When the sampled waveform does not contain an integer number of cycles duringthe sampling, spectral leakage occurs (the measured spectral energy leaks from onefrequency to another), so in the signal processing, windowing for the time domainwaveform can reduce spectral leakage.Discrete Fourier Transform (DFT) or FastFourier Transform (FFT) can represent a given signal as the sum of sine and cosine,which is the basis of spectrum analysis. When sampling for a non-integer number(e.g. 5.5) of cycles, since the FFT assumes that the data is a periodic repetitivewaveform, the spectrum returned by the DFT/FFT can be expressed as energy leak-ing from one frequency to other frequencies, which makes a high-frequency compo-nent that didn't exist in the original signal appear.

The MCM includes three built-in windowing algorithms: Hann Window, 4-term Black-man-Harris Window, and 7-Term Blackman-Harris Window. Windowing type isselected by the user according to the type of collected signals.

Filter

29 MCM User Manual

Time domain filtering calculation can calculate quickly because of its computationalcharacteristics, but the filtering effect is not as effective as frequency domain filtering.Currently, frequency domain filtering is supported by the built-in plug-in of MCM. Thecurrent filter in frequency domain uses Butterworth filter coefficient. The filter typecan be selected from Low Pass, High Pass, Band Pass and Band Stop. The defaulttype is High Pass.

1. Frequency0 and Frequency1 are the cutoff frequencies. If the filter type is Low Pass or High Pass, the value of Frequency0 will be the cutoff frequency. If the filter type is Band Pass or Band Stop, the smaller value of Frequnecy0 and Frequency1 will be the lower cutoff frequency and the larger value of Frequnecy0 and Frequency1 will be the higher cutoff frequency. The range of Frequency0 and Frequency1 can be set as [1, ConvertClockRate/2-1].

2. Order is the filter order, the range of which can be set as [1,10].

The operation interface is as follows:

1. Plug-in list: Currently there is a time domain feature plug-in and frequency domain feature plug-in. When you switch the plug-in time, the corresponding feature value of the plug-in will be shown below for the user to select.

2. Signal option: List of all selected channels. Click on the selected signal and you can choose the feature focused by the signal in field 3.

3. Feature value option: You can select the desired feature which will be listed in field 4 and the value will be calculated in real-time.

4. The list of selected features and the corresponding values.

Feature ListThe following table introduces the name and the corresponding description of fea-tures provided by the built-in feature plug-in of MCM. There are totally 26 features oftime domain and frequency domain data streams.

Feature Name Description

Mean Calculates the average value.

Max Maximum of Y-axis.

Min Minimum of Y-axis.

Peak_To_Peak Peak-to-peak value (the absolute difference between the maximum and minimum of Y-axis)

Median After sorting the values, takes the value in the middle as the median.

31 MCM User Manual

RMS The root-mean-square is the expression of the generalized mean of the power of 2.

Positive_Pulse_Width Positive pulse width (the time difference from the first rising edge to the first falling edge of the intercepted signal)

Negtive_Pulse_Width Negative pulse width (the time difference from the first falling edge to the first rising edge of the intercepted signal)

Positive_Duty_Cycles Positive pulse duty cycle

Negtive_Duty_Cycles Negative pulse duty cycle

X of Maximum The maximum value of X-axis data in a piece of data

X of Minimum The minimum value of X-axis data in a piece of data

Frequency Number of occurrences per unit of time

Standard Deviation Arithmetic square root of the variance

Variance The arithmetic square root of the variance is called the standard deviation of the random variable.

Coefficient of Variance The coefficient of variation of the data is the value obtained by div-ing the standard deviation of the data of the group by the average and then converted by percentage conversion.

Kurtosis The kurtosis measures the kurtosis of the probability distribution of real random variables.

Skewness Sample variance

Crest Factor The value obtained by dividing the amplitude of the waveform by the waveform RMS.

Range of Maximum Finds the maximum value within the specified range.

Local Maximum Finds the corresponding maximum value of the region from the input range.

Local Minimum Finds the corresponding minimum value of the region from the input range.

Percentile Percentile is a statistical term. Sorts a set of data from small to large and calculates the corresponding cumulative percentile.

Shape factor Root mean square value divided by absolute mean.

Impulse factor Peak value divided by absolute average.

Clearance factor Generally used to detect the wear and tear of mechanical equip-ment. If the enthalpy index does not change much, the ratio of the effective value to the average value increases, indicating that the gap increases due to wear, so the effective value of the vibration energy index increase faster than the average value, and the clear-ance factor also increases.

3 Introduction of Measurement Analysis Mode

Usually, during the modeling period, the equipment in the preventive maintenancesystem requires a tool to monitor the specific features that can be used to determinethe health of the device. This model is a tool designed for users to observe, buildmodel, analyze, and find key features. After the influential features have been figuredout by the analysis, the subscription and calculation of features can be implementedin Measurement Control Configuration.

After WebAccessMCMView.exe is executed, the user must log in as Admin to oper-ate in Measurement Analysis mode which will use all the functions of data acquisitionmodule and cannot be enabled with other modes together at the same time. Afterlogging in with your account and password, you can select "Measurement Analysis"to enter in the measurement analysis mode.

The parameter of frequency is White noise, which refers to thetolerance for white noises and the range is set to 0 to 1. The default is 0.1. The larderthe value, the less the noise of the value is allowed. Note that if the value of thisparameter is too large, then the complete waveform may not be found and the fre-quency won't be measured or the measured frequency is inaccurate.

Maximum_in_range can be configured by three parameters: Major_Search,Range_Width and Multiplier.

Major_Search is what the user mainly want to search. In time domain, it representsthe time and in frequency domain, it represents the frequency band Hertz, corre-sponding to "Fs" on the picture.

Range_Width is the searching range of Major_Search, corresponding to "Fd" on thepicture.

Multiplier indicates that the searching can be done by non-integer multiple times. Ifthis value is equal to Major_Search, the searching will be done by way of multiple fre-quency, corresponding to "Fm" on the picture.

The default initial values of these three configuration parameters will be recom-mended according to user's configurations. What's more, the output mode of this fea-ture is array output which will output the maximum array existed in the rangespecified by the user.

Local_Maximum and Local_Minimum's parameters are Out_Count_Max,Local_Range_Max and Out_Count_Min, Local_Range_Min respectively.

Out_Count indicates how many pieces of the area's maximum or minimum valuesoutput from the beginning that are requested. The default is 10, which means the first10 pieces of the area's maximum or minimum values are requested. If there are lessthan 10 pieces of data, then only the existed maximum or minimum values will beoutput.

Local_Range specifies the maximum or minimum value of the area. The defaultvalue of Local_Range_Max is 3, which means if the value of a point is larger than thevalues of the three points to the left and the three points to the right, then the pointhas a maximum value of the area. After all maximum values of the area have beenfound, these values will be sorted in sequence and output as required by the user.Similarly, Local_Range_Min specifies the minimum values.

4 MCM Catcher (WOGenerator and Worker) for Data Storage

In intelligent manufacturing and machine state detection and analysis maintenanceapplications, it is far from enough to display data remotely with a viewer. Users usu-ally need to store the feature data for further analysis and diagnosis, and that's whyMCM Catcher was developed. By using Catcher, users can easily store the featuredata of one or more running MCM Device Servers as required files with specifiedstrategy, column format, title and file format locally or remotely.

MCM Catcher is composed of two parts. Worker Generator is used to generate ormodify "wo" work order files. This software UI enables users to specify one or moreMCM Device Servers to be stored, the feature data to be subscribed, the feature datato be stored, the storage path, the file format (txt or csv), the storage format (e.g. title,data format, etc.), the storage strategy of feature/raw data (e.g. the Polynomials ofsubscribed feature/raw data can be easily edited for specifying the storage strategy,so that the feature/raw data is greater than a certain value), the storage strategy offile (e.g. the time and data count of single file, and the total size of all files) and thenaming rule of single file. "wo" work order files that have already been generated canbe opened and edited by Generator. Worker is used by the user to choose the wo fileand store feature/raw data according to the content specified in the wo file. The stor-age process can be started and paused, and the UI has the data transferring indica-tor to indicate the transfer speed.

If a MCM project is already running on your server and is in measurement control runscenario, then the two steps above can be ignored.

Step 3: Generate a wo file by Worker Generator.

Step 4: Select the wo file by Worker and start or stop the storage process.

After the four steps above, the feature value of the server specified by MCM is easilystored. The user can conveniently view, import and model data files, or model or pro-cess data with third-party tools.

4.3 Catcher User GuideWhat is the "wo" file?

"wo" is the abbreviation of "Work Oder". In MCM, the wo file is also called the workorder file that can be configured with the UI of Generator and be saved as a file withthe suffix wo. In this file, the xml format is used for describing the storage path, for-mat, storage strategy, file strategy, etc. A configured wo file can be loaded to Workerand implemented. The data of the specified MCM Device Server will be captured asdetermined in the wo file and saved as a file.

The MCM 2.0 device server has a built-in user with the "Monitor" permission named "Monitor", and the default password is 123456. This user name and password can be used to log in to the system if not modified by the user.

Rescan: Try to log in to all device servers listed in the current Feature/Streaming Data selection with the user name and password already entered. The device server list in the Feature/Streaming Data selection shows the MCM device serv-ers in the current LAN automatically searched out when Generator is enabled. After clicking "Rescan", the device server list in the Feature/Streaming Data selection will update. The online device servers currently running in the mea-surement and control operation mode are displayed as enabled (black), and the unavailable ones are displayed as disabled (grey by default). After entering the new user name and password again, the user needs to click "Rescan" again to update the status of the current MCM device server list.

(1) If the LAN is automatically searched out, please check if the current deviceserver is online. The user can open MCM Viewer and check the UnManageddevice server list on the Viewer Homepage. If none of them exist, it means thatthe server is offline.

(2) If the login name and password are correct, and if you can log in to thisserver. You can try to manage using the same login name and password inMCM Viewer.

(3) If the MCM device server is in the measurement and control operation mode.The user with the "Monitor" permission can only log in to the server running inthe “measurement and control operation mode. If your server is currently in themeasurement and control configuration mode, then you are not permitted to login to Generator.

(4) If the MCM device server is in the measurement and control operation mode,and if a selected project starts and is in the "Running“ status. If your server is inthe measurement and control operation mode, and you open a project withoutstarting it, there is no feature data, or the server cuts the project (the new projectis from a different acquisition card or other channels), and the selected featuredata no longer exists.

2. Feature/Streaming Data Selection:A list of slave machines. Generator will automatically search the list of slavemachines in the LAN and list it in this field. You can also click "Add" to add theMCM device servers you need. When you click "Add", the dialog box below willpop up for you to enter the Server IP address and computer name you want toadd manually.

When the user enters the correct login name and password in the "Login Infor-mation" field and clicks "Rescan", the list will be automatically updated, and thestatus will change to "Available" in the slave machine which has an operationmode and can be logged in.

5. Record Format (Feature/Streaming Data Storage Field and Policy Setting)

69 MCM User Manual

Record Timing: Sets the timing for storing a record. The slowest record will be the benchmark bydefault. When features of multiple slave machines are selected for storage atthe same time, the different device server parameters will cause difference inthe frequency of feature generation and sending. And when a piece of record isstored, the default setting is that the storage will start when all the features arein place and some of the device server features which are sent faster will beignored. Of course, in addition to the default mode, the user also selects otherbenchmarks through the drop-down menu. For example, you can choose a cer-tain feature of a certain MCM device server as the benchmark and under thisbenchmark, the closest value to this benchmark will be selected as the featuresof other device servers to be stored.

Select this wo file in Worker, the contents in the data file generated by the storage areas follows:

6. Log PolicyIt is the file generation policy setting. The captured data will be divided into multiplefiles for storage according to a certain policy, and the dividing method can depend ontime and data count:

Time, each file contains ** minutes: The length of time that a single file con-tains. Please note that the length of time means that the time difference between the first and last piece stored in a single file is** minutes.

Count, each file contains ** records.The number of records that a single file contains. It refers to the number ofrecords stored in a single file, which is consistent with the number of DataReadyevents of the DAQNavi acquisition card. Each time a DataReady event occurs,there will be a piece of data which has a group of feature values.

Overall file size limitation.The limit that the storage data can take up the disk space. You can set the limitto GB (limited to ** GB), or choose unlimited to store until the disk is full.

7. File NameSets the file naming rules. Generated storage files will be named according to thedefinition of this rule which is defined using the C language format definition symbols.The rules are as follows:

%i: The serial number will be represented by 1, 2, 3.... %d: The date on which the data is archived and will be represented by a certain

year, month and day. %t: The time when the data is archived and will be represented by a certain

hour, minute and second.

The following are some simple examples:

1. The default format is "%i Station1 %d-%t" and the generated file formats will be as follows"0 station1 12.01.2018-08.17.08.csv"?

"1 station1 12.01.2018-08.17.14.csv"

"2 station1 12.01.2018-08.17.20.csv"

2. The format is defined as "%i MyStation-%t" and the generated file formats will be as follows"0 MyStation-10.17.08.csv"?

"1 MyStation-10.17.14.csv"

"2 MyStation-10.17.20.csv"

3. The format is defined as "%i-%d-%t" and the generated file formats will be as follows

75 MCM User Manual

"0-08.01.2018-10.17.08.csv"?

"1-08.01.2018-10.17.14.csv"

"2 -08.01.2018-10.17.20.csv"

4.4.2 txt FormatComparing with csv format, the setting for txt format is only different in Record For-mat field, so this section focuses on the Record Format setting for txt format.

Title FormatWhen you edit the title of a recorded storage in the txt file, the title will appear in thefirst line of the file header for only once, but one line will be added to the record everytime when a set of data is collected.

The format symbols %d, %u, %f, %i, %x, %g, %e, %o are numeric outputs, %s is astring output, and the syntax rule is the same as that of C language.

Record TimingThe benchmark setting of the record is the same as that for csv format. The slowestrecord will be the benchmark by default, that is, a record will be stored when all thenecessary data is updated. In addition to the default mode, you can also choose thefeature of a device server as the benchmark. In this case, the closest value will beselected as the feature values in other fields. The reason for setting the benchmark isto solve the problem of difference in the efficiency of data sending from different serv-ers. When selecting a fast machine as the benchmark, duplicate storage will occur inthe same timestamp of the slow machines. And when selecting a slow machine asthe benchmark, the fast machines will lose some data. Benchmark is only used whenrecording the data of multiple MCM device servers at the same time. There is storagetiming sequence competition between servers. When only the data of one deviceserver is stored, the timestamp for each piece of data is the same.

Record ConditionSet the conditions to be recorded. The steps are the same for csv. You can first click"Record Condition" field and then the Space key. The drop-down list menu will pop upautomatically. When entering the keyword, the options related to it will pop up syn-chronously. You can select the desired feature or index as the feature of the variablesto edit the expression.

4.5 Worker Usage GuideWorker is used to load a work order file, capture the feature, as well as store and per-form storage according to the policy defined in the wo. The Worker UI and instruc-tions are as follows:

1. Open Button: Open or switch to the wo file, and then click this button, a file selection dialog box pops up for you to select the wo file to run. Opening Worker through the Start menu of the computer ->Advantech MCM->WebAc-cessMCMWorker is the same as clicking "Open". A file selection dialog box will pop up for the user to select the wo file to run.

2. Connection Indicator: Is the indicator of the connection status. When the user selects a wo file, the indicator status indicates if the MCM device server speci-fied in the wo is currently available for connection. The cases are as follows:

(1) Dark green: The default color when a wo is not selected. If the MCMdevice server is disconnected and it cannot be connected the LED indicator isdisplayed in dark green. If the device server is not powered on, the status fieldwill also prompt "Invalid work order file: no online server".

(2) Light green: the MCM device server is online and available for connec-tion.

3. Start/Stop Button: Click to start running. When the feature has a single file stored, you can see a prompt in the status field indicating that the file is saved. Click "Stop" to store the data as a new file, and then click "Start" again to store the new file.

4. Work Status Indicator Field: Records the change of status and the time of occurrence. When the MCMdevice server in the wo is disconnected, the scene changes to the measure-ment and control configuration, which causes the connection to be unavailable.Changing project means there is no feature. This field will display the promptinformation to inform the user. When the feature storage starts, stops, and a

single file is generated, there will also be a prompt for information. The user cankeep up with the status of Worker through this field.

5. Data Received Indicator:Indicates data transmission and storage status as follows:

(1) Gray, data transmission and storage have not yet started and are in discon-nection status.

(2) Green, data transmission and storage has started and are in connection sta-tus.

(3) Flashing green, data transmission and storage is in process and the flashingfrequency is proportional to the data transmission and storage speed, but it isonly an indication of the speed without one-to-one correspondence. When thefrequency is greater than 10Hz, the indicator will be constant green withoutflashing.

6. Exit Button: Click this button to exit Worker. If you are currently in the "Start" status, click "Exit" to automatically stop and exit. The user can also click "Close" in the upper right corner in the "Run" window of Worker.

4.6 Catcher FAQQuestion 1: What is the relationship between Catcher, Worker and WorkerGenerator?

Answer: Catcher is the name of a product in MCM. It is designed to store remotelyor locally the feature data or index in MCM Server as a file the user needs accordingto the policies, file formats and field formats specified by the user. Catcher has twotools. The first one is Worker Generator which is used to generate work order files(wo files). The user sets to store one or more MCM device servers data and the datato be stored, the feature storage format and the policy through the configuration UIprovided by Worker Generator, and finally saves as a work order file (a file with suffixwo). The second one is Worker which is used to import the wo file and start or stopexecuting the storage. There will be some fields to display the information of statuschange as well indicators to indicate the connection and operation during execution.

Question 2: How to start Worker and Worker Generator?

Answer: Currently, the installation package pkg_mcm_catcher.exe provided by MCM2.0 is the installation package of Catcher products. After double clicking to run thepackage, the Catcher Work Generator and Worker shortcuts will appear in the Startmenu of the computer, namely WebAccessMCMWOGenerator and WebAccessMC-MWorker.

Question 3: Does the wo created on machine A only run on machine A?

Answer: No. A wo created on any machine can run on Worker of any machine thathas Catcher installed. Please note that if the storage path defined in the wo file youselect does not exist, it will be stored in the specified default path with a prompt onthe status of Worker.

Question 4: After starting Generator, there is the MCM device server machineA, but the machine node is not enabled after filling in the user name and pass-word, why?

Answer: Please check as follows:

79 MCM User Manual

If the machine is currently online. You can try to open MCM Viewer to see if the machine is on the machine list on the Homepage.

If the user name and password are correct, you can try to manage this machine with the same user name and password on MCM Viewer.

If the current machine is running in the measurement and control operation mode.

Question 5: After starting Generator, MCM device server machine A is withoutany feature after filling in the user name and password and clicking open theenabled machine node, why?

Answer: Please check the project running on the server to see if a feature or index ischecked on "Display" page. If there is no feature or index displayed for the runningproject you select in the measurement and control operation mode, the list will beempty even after clicking open the server on Generator.

Question 6: The Log Policy in the wo generated on Generator is 1 min, but afterimporting into Worker, the file generated has not changed every 1 min by thename, why?

Answer: The time (each file contains 1 min) set in the Log Policy corresponds to thetime difference between the first and last piece in a single file which is 1 min, and thiscan not be judged from the file name.

Question 7: The Record Condition is always wrong and indicated in red onGenerator, why?

Answer: First of all, the syntax is C language format, and secondly it must be editedwith feature or index as the variables. And the constant expression is legal but mean-ingless. Please check if there are illegal spaces.

Question 8: Which are the current storage formats?

Answer: The version only provides txt and csv formats currently. But in the future,other formats such as db will be added according to users' requests.

Question 9: How to choose the timing when storing the data of multiple serversat the same time?

Answer: First of all, when storing the data of a server, since the default timestamp foreach feature data of a server is the same, there is no timing problem. However, whenstoring the data of multiple servers at the same time, there will be algorithm differ-ences caused by different frequencies of data sending to compose the data capturedfrom different machines into a "Record" archive. Thus when choosing different tim-ings, different algorithms will be used. The basic concept of the algorithm is to deter-mine a key feature/streaming data (that is, the timing you set) first, take thetimestamp of the key feature/streaming data as the benchmark and find out the time-stamp closest to this benchmark in the feature/streaming data of all the other servermachines to store. By default, the slowest one will be the benchmark, that is, allserver data near the same timing arrive with only a stored record generated.

Question 10: What happens if the single file size exceeds the overall file sizelimit when the log policy is set to be that each file contains N minutes or Nrecords?

Answer: If there is enough disk space, the storage will run according to the specifiedstorage for each file. When the process stops or it needs to switch files, please checkif the limit of overall file size is exceeded. Since the extra part will be deleted from thefile, when the process stops, the data visible to the user is the file that meets theoverall file size requirement after deletion.

Question 11: The Server project is running normally, and the wo configurationinformation imported into Worker is also correct, but it prompts that the con-nection is not available.

Answer: Please check if the firewall of the server machine is enabled. You can con-sider disabling the firewall or adding the MCM service to the firewall white list. Runthe Worker machine to see if the anti-virus software has been enabled, and close theanti-virus software or add it to the trust list.

By default, if your firewall is enabled when you install the MCM 2.0 Server installationpackage, the installation package will automatically add the server to the firewallwhite list. But if you do not enable it before installation, the installation package willnot process automatically, and if it is enabled after installation, this may cause theremote Viewer or Catcher failing to connect to this server.

Question 12: It pop ups that the feature can not be found.

Answer: Please check if the project currently running on the server machine specifiedin your wo still has the feature subscribed to in the wo.

Question 13: The indicator is always on but not flashing?

Answer: The current speed to run and store the record is slightly fast, exceeding theupper limit of the UI indicator refresh rate, so it is always on.

Question 14: Why data can not be stored on multiple servers when Workerstarts running?

Answer: This may be due to the fact that the frequencies of data sending from multi-ple servers are different. And if the benchmark of timing is set to be the feature of theslowest server, it is possible that no data storage can be seen after Worker has beenrunning for a long time.

A.1 Time Domain Preprocessors Moving averageFiltering is a common signal processing technology which can remove redundant sig-nal noise in measurement signals, e.g. removing high frequency signal in low fre-quency signals which change slowly. The built-in plugin of MCM provides two type ofmoving average algorithm coefficients, one is the unweighted filtering and the other isthe weighted filtering.

The filtering algorithm simply takes the averaging value of the neighboring points asthe new value of the point. The amount of neighboring points is the width of the win-dow. There are two ways to define the window. One is the width of the window, e.g.the filtering function parameter of Matlab; the other is defined as 2*width+1 in MCM.The Moving average algorithm can also be used as a low-pass filter, because it canreduce the amplitude of the most active point by averaging the value of neighboringpoints, which is similar to filtering the high-frequency signal.

The weighted moving average algorithm means to add the weight of the triangularcoefficient during the averaging. Taking the filtering of five points (width=2) as anexample,

The weight of triangular coefficient of the following 3~11 points:

The UI and parameters are as follows. After the signal is selected, choose the Pro-cessing Method on the right side as the Moving average and set the parameter width.

This algorithm UI can configure the parameter and the range.

1. Width: The filter width of average filtering. The actual calculated number of points is 2*Width+1. The range of this parameter is [1,min(128, SectionLength/2-1)] which is related to SectionLength configured on acquisition page.

2. Weigh function is enabled.

FIR FilterThe finite impulse filter (FIR filter) uses the FIR filter specified by the FIR coefficient tofilter the collected original signals. The current FIR filter in built-in time domain pre-processing plugin uses Butterworth filter coefficient. The filter type can be selectedfrom Low Pass, High Pass, Band Pass and Band Stop. The default type is High Pass.

Parameter and UI configuration range:

85 MCM Series User Manual

1. Frequency0 and Frequency1 are cutoff frequency. If the filter type is Low Pass or High Pass, the value of Frequency0 will be the cutoff frequency. If the filter type is Band Pass or Band Stop, the smaller value of Frequnecy0 and Frequency1 will be the lower cutoff frequency and the larger value of Frequnecy0 and Frequency1 will be the higher cutoff frequency. The range of Frequency0 and Frequency1 can be set as 1, ConvertClockRate/2-1].

2. Order is the filter order, the current range of which is [1,10]. The larger the Order, the steeper the frequency response.

A.2 Frequency Domain Preprocessors Remove DCAs the name implies, DC is removed in frequency domain.

Window FunctionWhen the sampled waveform does not contain an integer number of cycles duringthe sampling, spectral leakage occurs (the measured spectral energy leaks from onefrequency to another), so in the signal processing, windowing for the time domainwaveform can reduce spectral leakage.Discrete Fourier Transform (DFT) or FastFourier Transform (FFT) can represent a given signal as the sum of sine and cosine,which is the basis of spectrum analysis. When sampling for a non-integer number ofcycles, since the FFT assumes that the data is a periodic repetitive waveform, thespectrum returned by the DFT/FFT can be expressed as energy leaking from one fre-quency to other frequencies, which makes a high-frequency component that doesn'texist in the original signal appears.

MCM includes three windowing algorithms: Hann Window, 4-term Blackman-HarrisWindow, and 7th-order Blackman-Harris Window. Windowing type is selected by theuser according to the type of collected signals.

FilterTime domain filtering calculation can calculate fast because of tis computationalcharacteristics, but the filtering effect is not as effective as frequency domain filtering.Currently, frequency domain filtering is supported in MCM. The current filter in fre-quency domain uses Butterworth filter coefficient. The filter type can be selected fromLow Pass, High Pass, Band Pass and Band Stop. Frequnecy0 and Frequency1 arecutoff frequency. If the filter type is Low Pass or High Pass, the value of Frequency0will be the cutoff frequency. If the filter type is Band Pass or Band Stop, the value ofFrequnecy0 will be the left cutoff frequency and the value of Frequency1 will be the

right cutoff frequency. The range of Frequency0 and Frequency1 can be set as [1,ConvertClockRate/2-1].

Order is the filter order, the current range of which is [1,10]. The larger the Order, thesteeper the frequency response.

A.3 Feature Value List MeanThe mean is the average of the numbers: a calculated "central" value of a set ofnumbers.

MaximumThe maximum value of Y-axis on the plot.

MinimumThe minimum value of Y-axis on the plot.

Peak-to-peakPeak-to-peak (pk-pk) is the difference between the maximum positive value and themaximum negative value of a waveform.

MedianThe median is a value separates the higher half of a bunch of data, a population, or aprobability distribution, from the lower half. For a data set, it is regarded as the "mid-dle" value.

RMSIn statistics and its applications, the root mean square (abbreviated RMS or rms) isdefined as the square root of the mean square (the arithmetic mean of the squares ofa set of numbers).

Positive Pulse WidthThe Positive Pulse Width measures the time from the first rising edge to the first fall-ing edge.

Negative Pulse WidthThe Negative Pulse Width measures the time from the first falling edge to the first ris-ing edge.

Positive Duty CyclesThe Positive Duty Cycles is calculated by taking the ratio of their corresponding Pos-itive Pulse Widths to the Period.

Negative Duty CyclesThe Negative Duty Cycles is calculated by taking the ratio of their correspondingNegative Pulse Widths to the Period.

X of Maximum

87 MCM Series User Manual

The corresponded X-value where the maximum value of Y-axis locates. When itcomes to frequency domain, it is regarded as the basic frequency of the signal.

X of MinimumThe corresponded X-value where the minimum value of Y-axis locates.

KurtosisIn probability theory and statistics, kurtosis is a measure of the "tailedness" of theprobability distribution of a real-valued random variable. The fourth standard momentcan be define as

, where μ4 is the forth central moment and σ is standard division.

In normal situation, kurtosis is defined as fourth cumulant over square of secondcumulant. It’s equivalent to fourth central moment over standard division minus 3.

This is also called excess kurtosis. The minus 3 introduced here is to let the normaldistributed kurtosis to be 0.

The WebAccess/MCM here uses Excess Kurtosis.

Skewness

X is the mean value of the samples, m2 is third sample central moment, m2 is secondsample central moment, i.e. sample-mean difference square.

Crest FactorCrest factor is a waveform-related dimensionless quantity. It’s derived by the magni-tude over RMS.

Standard Deviation

MCM Series User Manual 88

Appendix A

Algorithm

Library

Standard division (σ) is mostly used in measuring the dispersion of a set of numbers.The definition is: the square root of the diviation.

Where μ is the mean value.

VarianceVariance is a term in Applied Mathematics. In Probability theory and Statistics, vari-ance is used to describe the dispersion of a random variable, which implies the differ-ence to the expected value. Here we set variance as square of Standard Deviation.

Coefficient of VarianceThe Coefficient of Variance is also called Coefficient of variation. It’s defined as theratio of Standard Deviation and Mean value. The Coefficient of variance would onlybe significant when the mean value isn’t 0 and it’s normally used in the situationwhen mean value is larger than 0. The value can be described as below formula,where s is standard deviation and the mean is x.

Range of Maximum

The harmonics and the general formula of the sideband is as following:

In the WebAccess/MCM, users can enter below parameters:

Fs: The first harmonic to be searched

Fm: Interval between harmonics

Fd: Range in searching the harmonic

The output value on the other hand, is a matrix pairing the frequency and magnitude,up to maximum 128 sets.

Local Maximum

89 MCM Series User Manual

As literally, the local maximum finds out the local maximum value according to thesetting of Output_count_Max and Local_Range_Max. The Output_count_Max setsthe how many values to be found in every calculation. The Local_Range_Maxdefines the range to search for the local peaks. For example, when 5 is given to LocalRange Max, a local maximum is derived when the value is found to be maximum inadjacent 5 on the coordinates. The result of searching would be sorted by arithmetic,output to the users in matrix in a quantity that Output count sets.

Local MinimumSimilar to local maximum, input two parameters, the count and range to search forthe local minimum.

PercentileIn this algorithm, every acquired raw data would be sorted by ascending power atfirst. Then, a corresponded percentage in this series will be given to every singledata. For example, the largest value will be given 100% and 0% for smallest one. Theusers should enter the percentage to get the value from the series.

Shape factorShape factor is one of the dimensionless quantities in AC signal. It can also be repre-sented as kf. It’s the ratio of RMS and absolute mean value.

Impulse factorImpulse factor is calculated as peak value over the absolute mean value, where peakvalue is half of peak to peak value.

Clearance factorThe clearance factor is normally used to know the significance an equipment/mecha-nism is under abrasion. The value can be calculated by below formula,
