Connections1

1.1 Supported connections types

This application supports several connection types:

- Direct communication via serial port (via optical probe or RS232/RS485 cable)- Via GSM modem- Via PLC module- Via web service (for testing only)- Via ZigBee module

Connection type and parameters can be set on connection, PLC and DLMS parameters tabs.

1.1.1 Direct communication

Direct serial communication is the simplest, transparent method of communication with meter. Fordirect communication, optical probe or serial cable to the meter are needed. To use direct connection,choose “Serial” in “Connection type” combo box, and set other parameters as needed.

1.1.2 GSM communication

GSM communication is way of communication with meter via GSM modem connected to COM port.GSM modem must be properly installed in the system. To use GSM connection, choose “GSM” in“Connection type” combo box, type phone number in “GSM” textbox and set other parameters asneeded.

1.1.3 PLC communication

PLC (Power Line Communication) is way of communication with meter via power lines, with eventualuse of GSM modem connected to COM port. GSM modem must be properly installed in the system.

To use PLC connection, choose “PLC” in “Connection type” combo box, type phone number in “GSM”textbox (if PLC device we want to connect to is connected to remote GSM modem), set PLCparameters and set other parameters as needed.

1.1.4 Connection parameters

In “Connection parameters” tab user sets parameters needed for connection to meter, COM port(COM1-20) and baud rate.In “Connection type” user sets connection type – Serial (for direct communication), GSM, PLC, IP TestService (for application testing) and ZigBee.In “Connection parameters” group user sets standard connection parameters – data bits, parity bits,stop bits, number of retries, timeout (in ms), GSM (phone number used to communicate with distantGSM modem in GSM, PLC and ZigBee communication), ZigBee address and meter password.

1.1.5 PLC connection parameters

Parameters for PLC communication are located in „PLC” tab – Response Timeout (in ms), number ofrepetitors in the network, Repetition Timeout, PLC Baud rate (communication speed between PLCcommunicator and meter) and max telegram length.

1.2 DLMS connected parameters

The most significant DLMS parameter is HDLC address, used to determine particular meter innetwork we want to communicate with. When working with Mikroelektronika meters, HDLCaddress should be entered in format 0001xxxx, where "xxxx" stands for four last digits taken from

serial number (displayed on meter). In PLC communication is also used to select a repetitor.Conformance block is also worth noting. Other parameters usually do not need to be modified,since all of them are set to default values.

1.2.1 Conformance Block

Conformance block parameter can be set by direct entry of each of three bytes, or by setting it bit bybit. When “Edit” button is clicked, separate window with all bits shown pops up, and specific value canbe set.

1.2.2 Coded HDLC

If parameter CodedHDLC in configuration file “MesmetOneClick.exe.config” has value False, HDLCaddress will be sent as it is written. If CodedHDLC is True, address will be coded by Mikroelektronika’salgorithm.

1.3 Connection manipulation buttons

There are eight icons in toolbar used for operations with meter. From left to right: Open Serial Port,Connect, Disconnect, Close Serial Port, Update HDLC, Read, Write and Help.

1.3.1 Open Serial Port

After clicking on “Open Serial Port” icon, physical level of comunication is opened. If direct serial, orZigBee or PLC communication without GSM modem is selected, this way serial port is opened forcommunication. If GSM communication is involved, this way physical GSM connection with meter ormodule is opened. If serial port is opened successfully, an icon (depending of communication type)appears in lower right corner.

GSM connections stays open until serial port is closed, and IS NOT affected by Connect andDisconnect!

1.3.2 Connect

If serial port is open, after clicking on “Connect” icon application makes an attempt to establish a DLMScommunication with meter. If establishing communication succeeds, icon in lower right corner turnsblue. If it fails, icon stays gray, and error report is shown in status bar.

If serial port is closed, it is not possible to establish comunication with meter.

1.3.3 Disconnect

After clicking on”Disconnect” icon, existing DLMS connection is cancelled. Connection status icon inlower right corner turns gray.If DLMS connection doesn’t exist, message “Not connected!” is shown in lower right corner.

It should be noted again that GSM connection stays open after DLMS disconnect!

1.3.4 Close Serial Port

After clicking on “Close Serial Port” icon, physical level of communication with meter is closed. Serialport is again available for all other applications. Icon with communication type disappears from lowerright corner.

1.3.5 Update HDLC

If serial port is open, it is possible to update HDLC address which we access, by entering new addressin “HDLC Address” field on “DLMS Parameters” tab, and then clicking on “Update HDLC” icon. This wayit’s possible to change the meter user is accessing without breaking physical communication.

1.3.6 Read

After clicking on “Read”, application attempts to read data from active object (currently visible object).When tarriff table or any simple object is selected, all displayed atributes are read, and when clockobject is active, user can select the attributes he wants to read. If no attributes are selected, all of themare read.When one of the profiles is selected, user can select time slot for reading, and captured objects fromwhich he wants to read. If no captured object is selected, all of them are read.

1.3.7 Write

After clicking on “Write”, application attempts to write selected attribute into meter object.It’s only possible to write into “Clock” (only checked attributes) and “Tarriff table” (complete table)objects.If there is no active connection, or if user attempts to write into an read-only object, error message isdisplayed in status bar.

Objects2

Mesmet OneClick provides possibility of access to many objects in DLMS meters.

2.1 Simple objects

Simple objects accessible by MesmetOneClick applications are Clock and Error objects.

Clock

Clock is selected by clicking on “Clock” in “Basic Objects” group on “Objects” tab.All attributes are defined by DLMS standard.System time can be written into meter by checking time attribute, and selecting “System” option.Afterwards, during write operation, application takes system time from computer and writes it intometer.

Error objects

Error object is selected by clicking on “Error objects” in “Basic Objects” group on “Objects” tab.It’s possible to read values of “ALARM Meter cover opened”, “Battery low” and “Date time invalid”.

2.1.1 Billing registers

Billing registers are objects used for measuring energy consumption, current and maximum power.One of billing registers is selected in group “By tariff” by choosing appropriate element (type of power orenergy – active or reactive, positive or negative, by quadrant), then what is measured (energy, currentpower, maximum power) and tariff (tarriffs 1-8, or “total” for summary). After that, click on “Select” buttonin the group.

2.1.2 Network quality registers

Network quality registers are object used for measuring current, voltage, power factor, supply frequencyand harmonics of currend and voltage, for every phase separately. User can select one of the registersby choosing an item from appropriate combo box and clicking “Select”.

2.1.3 Profiles

Profiles are objects used for sampling the values from selected registers in appropriate time periods.Since profiles can be very large, it can take some time to complete their reading. Therefore, it’s possibleto narrow selection, by choosing appropriate time interval, and after reading is started, by selecting onlyneeded objects.If a problem occurs during reading (e.g. terminated GSM call), application shows the part already read.

After such error, it’s necessary to disconnect and connect again to proceed communication.

Billing profile

Billing profile usually contains data about billing registers and samples their values once a month.

Load profile

Load profile usually contains data about maximum power registers.

Event log

Event log usually contains data about all important events (e.g. power failures, meter cover opening...).

2.1.4 Tariff table

Tariff table is selected by clicking on “Tariff table”.Tariff table represents summary of three objects - Tariffication script table, Activity Calendar and SpecialDays Table. Those tables are interconnected. Tables “Seasons”, “Weeks” and “Days” are used for datafrom Activity Calendar, and “Special Days” table is used for Special Days Table class. Button “+” isused for inserting new rows into tables and “-“ button remove last row from tables.Field “Activate passive calendar time“ is connected to Activity Calendar class and is used to write timefor tariff table activation.It is not possible to edit tariff table before reading current tariff table.

2.2 Actions

Beside reading and writing, in MesmetOneClick application it is possible to execute several importantactions. Action buttons are located on “Actions” tab.All actions request confirmation.

2.3 Problems

If user tries to read from non-existant object, application will report error, but will not interruptcommunication.In case of any communication problem or any awkward behavior, universal procedure is:

- Click on “Disconnect”, then “Connect”- If that fails, try to close and reopen serial port, with parameters check (e.g. some

DLMS communication mods do not allow writing into meter)- If there is problem with connecting to meter, user should check:

- If appropriate communication type is selected- If connection parameters are OK- If HDLC address is correct (also check if “CodedHDLC” value is OK)- If exact phone number is entered

- If problem cannot be solved this way, feel free to e-mail us onMESMET-support@e-smartsys.com and we will response you as soon as possible.
