          Note: Virtual parameter can't use for event.
          Example 1:            Value of Virtual Parameter have address at 2012 is calculated as follow [2012] = [2000] + [2002. ]In which address 2000 and 2002 are two real parameters
          Example 2:

            IF [2000]>10 then [2005]=1
            IF [2000]<=10 then [2005]=2 
          Example 3:

            IF [2000]=1 And [2005]=2 then [2010]=5
            IF [2000]=!1 And [2005]=!2 then [2010]=[2007]+10
          Example 4:

            IF [2000]>10  then [200A]=1
            IF [2000]<10 And [2010]=1 then [200A]=5
            IF [2000]<10 And [2010]=!1 then [200A]=10

    o Unit: Unit of parameter

  • Save: click to finish
  • “Delete All”: click to delete selected parameters
  • Edit: click to edit this parameter
  • Delete: delete parameter

 Note: After Configure Parameter, you must synchronize (refer to 5.11 Synchronize Device for more details)

3.2 Configure Modbus Command

- Select Device, right-click, select Modbus Command

- Modbus Configuration page displays as below:

  • MODBUS CONFIG LIST (1)
    o Button “Edit”: click to edit Modbus Command. Modbus Command will display in (2) to edit
    o Button “Delete”: click to delete Modbus Command.
    o Button “Import”: click to import Modbus Command list from excel file
    o Button “Export”: click to export Modbus Command list to excel file
    o Button “Delete All”: click to delete all Modbus Command
  • ADD MODBUS CONFIG (2)

    o Response Location: Address of parameter in iConnector
    o Slave ID: Modbus ID of meter/sensor/device/instrument which connect to iConnector through RS485 port
    o Function Code: Function Code of Modbus Command. Function Code consist of read function and write function. In user manual of meter/sensor/device/instrument should mention supported function code.
    o Parameter 01: Starting address of parameter in memory map of meter/sensor/device/instrument
    o Parameter 02: Number of registers of parameter in memory map of meter/sensor/device/instrument
    o Button “Add”: Click to add new Modbus Command
    o Button “Update”: After click “Edit” button in (1), “update” will display. After editing Modbus command and click “Update” to save change.
      Note:
       Response Location in iConnector for read Modbus data :0x2000 -> 0x21FF
       Response Location in iConnector for write Modbus data: 0x3000 -> 0x307F
       After configuring, Modbus Command should be synchronized to iConnector (refer to 5.11 Synchronize Device for more details)
Example:
Configure modbus command for reading parameter Voltage, data type: float, from address 0000 on power meter (ID=32) and store at address 2000 (hex) on iConnector, using function 04 of modbus command. The configuration as follow:

Response Location = 2000

Slave address = ID=32 (decimal) =20 (Hexa)
Parameter 01 = Start Address = 0000
Parameter 02 = Number of register of parameter. Data type = float (4 bytes) = 02 register

 

3.3 Synchronize Modbus Parameter configurations and Modbus Command configurations to iConnector

Right click Device name, select Sync, and tick all type of configuration to synchronize to iConnector, click Sync, enter password to confirm permission

After successful synchronization, Text Synchronized should appear on 4 line of dialog box. If iConnector disconnected, message should appear to inform that synchronization will implement once iConnector connect to server.
