BackgroundThroughout the level 1 and 2 exercises we will be referring to “Mega Corp.”, a fictitious company derived frommany years of customer experience. The exercises will emphasize how OPC can provide value by providing asolution to real world problems. You will work though the entire Mega Corp. solution from leaning aboutbusiness needs too implementing a solution.

Mega Corp.Mega Corp. is a multi-national company and has numerous sites of various ages and types. They compete inthe tough modern world economy by providing good service and a quality product. Not all of their sites havelived up to their vision and are now the focus of targeted enhancements. Our project has to do with one ofthe older sites and an effort to increase its operational effectiveness.

The site, Station 3, is one of the older and smaller sites in Mega Corp.’s portfolio. The market it serves has agrowing demand and prefers to source locally. Station 3 is the only local supplier and is situated well in termsof market demand and competition.

Mega Corp. needs Station 3 to solve two immediate problems to satisfy the corporate targetedenhancements. First, the high tech industry moving into the area requires their supplies to be on time and aconsistent grade for their Just-In-Time (JIT) operations to be effective (and profitable). This is an immediateneed of the customer base. Second, the drain on the aging power grid is starting to affect all industrialconsumers and as such energy costs are rising sharply.

Line 1

Receiving Processing Inspection Packaging Shipping

Over the past six mont hs Mega Corp.’s Station 3 engineering staff has researched all aspects of the plant andfeels they have come up with a winning solution to their immediate problems. Since a JIT manufacturingprocess ramps up and down in real time based on customer need predicting future production is hit and miss.To keep availability the energy consuming machinery is constantly on, even in periods of low usage. Thesolution is to add control mechanisms to the machinery where they can be controlled based on the inflow of

source materials allowing them to use less power and still maintain availability. This will also allow theplanning of production around short periods of very high power costs.

Specifically the engineering staff found that source material coming into Station 3 was directly related toorders. It is also directly related to the energy required to produce product. If the source material volume islow machinery can be set to idle to save costs while still being able to process the incoming materials, abet at

Level 1 – OPC Fundamentals

Module 1 – The Evolution of OPC

Exercise 1.1 – OPC Client to Server ConnectionPurpose:

When designing an architecture for connecting the DCS to the production equipment an OPC connection waschosen because of the DCS’s existing OPC clien t capability. To understand how OPC makes a connection weneed to get some hands on experience so we can better determine how the components will communicateand where in our architecture the components will sit. We’re going to start with two of the most commonOPC products available today, the MatrikonOPC TM Explorer as the OPC client application which will connect tothe MatrikonOPC TM Server for Simulation and Testing.

Objectives:

This exercise demonstrates the mechanics of establishing a connection to an OPC server using an OPC clientapplication. For this exercise you are required to use the MatrikonOPC TM Explorer as the OPC client applicationto connect to the MatrikonOPC TM Server for Simulation and Testing.

1. Create a connection between an OPC client application and an OPC server.2. Create an OPC group object.3. Select items to add to the OPC group.4. Validate and add the selected OPC items.5. Read and write values.6. Note the OPC server and OPC group properties.

Exercise 3.3 – Transferring DataPurpose:

Mega Corp. head office also needs the production data for billing and forecasting. MatrikonOPC Hub andSpoke guaranteed data delivery mechanism is used to push the data from the local ODH to the corporateenterprise historian. Keeping the data local while also having it in the corporate head office means anyoneneeding the data has direct access to it. It also means that Station 3 has direct access to its data but is isolatedfrom other plants enhancing security.

Objectives:

This exercise demonstrates how to use an OPC HDA-based application to affect the transfer of archived datafrom one historian to another. During Exercise 3.1 – Desktop Historian Tag Management, a pair of blank tagswas created in the OPC Desktop Historian on your machine. Using OPC HistoryLink, you will transfer data fromyour partner’s Desktop Historian to the blank tags in your Desktop Historian. If this isn’t possible due toclassroom conditions then you will transfer data from yourself back to yourself using the same mechanisms.

1. Use HistoryLink to transfer data from one historian to another.2. Configure HistoryLink to recover from a disruption of network connectivity.

Module 4 – The OPC Specification for Alarms and Events

Exercise 4.1 – Alarm and Event SubscriptionPurpose:

Hardware monitoring and system maintenance are important to Mega Corp. The new hardware being used to

host the MatrikonOPC Server for Modbus is running in the manufacturing plant away from the normal ITpersonal. They have requested a mechanism to monitor and historize some of the system metrics. We will bedoing this already with OPC data so we will provide the Health Monitoring data as OPC data as well.

In addition the needs of IT the Control Engineers want to be immediately informed if there is an issue with thenormal operation of the hardware. For this we can use the alarming mechanism in OPC and provide the dataas OPC Alarms when the chosen system metrics are outside set parameters.

Objectives:

The OPC Specification for Alarms and Events was developed to allow for the creation of OPC servers that

would expose event notification information in devices and control systems and permit OPC A&E clients toaccess this information. This exercise demonstrates the establishment of the connection between Eventsource, OPC A&E server and an OPC A&E client.

1. Create an event source.2. Connect to the source using an OPC A&E Server.3. Subscribe to the event server with an OPC A&E client.

Module 6 – The Windows Security Framework

Exercise 6.1 – The Effect of the “Identity” Settings on OPC Server sPurpose:

This is a deeper dive into the security settings for COM. Understanding these settings will greatly enhance the

ability to customize the behaviors of the OPC servers. Knowledge of custom behaviors allows Mega Corp. totune their system architecture but also allows troubleshooters to identify and fix issues which mayinadvertently come up after maintenance.

Objectives:

The Launch and Activation and Access permissions determine who has authorization to call functions on theCOM object in question. The Identity configuration determines the permissions (i.e., authorization) that theCOM object itself is granted when attempting to perform this same function. There are certain behaviorsassociated with these settings that affect the functionality of your OPC architecture. This exercisedemonstrates some of these behaviors.

1. Configure the MatrikonOPC Server for Simulation and Testing to run as an application.2. Examine the effects of running the OPC Server for Simulation and Testing as the Interactive User .3. Examine the effects of running the OPC Server for Simulation and Testing as the Launching User .

Exercise 7.2 – OPC Server for Performance Monitor (Perfmon)Purpose:

Monitoring the host operating system is something IT does regularly. The problem comes when the controlengineering side of the business needs long term tracking of the host performance. Windows performancemonitor can log data to be imported in Excel. That’ll work but it’s often not practical. What is easier is to useMatrikon’s OPC server for Perfmon. It runs as an OPC server and exposes all the Windows performancemonitor data as OPC tags. This way data can be used in your process, alarmed on, or recorded for long termanalysis be an OPC Historian like OC Desktop Historian. An additional useful feature is that it can monitormany remote hosts at once.

Objectives:

We want to track the total CPU available on the host computer. We will attach to it with OPC Explorer to viewthe %CPU used by the idle process to determine what the CPU availability is.

1. Start OPC Explorer and connect to the OPC Server for Perfmon.2. Browse the available tags and find the CPU idle process metric (there are lots, it may take some

searching).

1. What host metrics would you need to use to know if an automation piece of software had deadlocked(halted but not exited)?

2.

Could you also use the same metric to determine if the automation piece of software was overloadingthe computers CPU?

3. Could you do the similar things with memory? What can you detect?

4. If combined with the OPC Server for Events which generates OPC Events could you create an automaticsystem to help determine the health of the hosts on a network?
