Dear All

I am trying to establish connection from MK-VI to Metrikon OPC over Ethernet modbus. On HMI,project file, IO_ports, config.dat and cimmod.dat have been configured for TCI modbus protocol, ethernet modbus slave and register mapping. what is the syntax on OPC server and where should I type the syntax to read the signal from MK-VI?

thank you,

 

MKVI Does not do OPC communications directly. The Cimplicity HMI can be setup to function as an OPC server. If you check the Cimplicity folder you should have an OPC Server program.. The help file is quite useful and should help with the setup. Beware not all Cimplicity's were shipped with OPC Functioning, in the early stages it used to be a purchased option.

 

The OPC item ID syntax for Mark VI Direct Unit is as follows:
"Mark VI Direct Network"."Mark VI Direct Unit"."Point name"

Where:
- "Mark VI Direct Network" is the name assigned to the Mark VI Direct
- "Mark VI Direct Unit" is the name assigned to the Mark VI unit in the site configuration file.
- "Point name" as defined in the UNIT_EGD.DAT in the unit specific configuration folder.

So for example:
UDH.S1. LTB1D1
Accesses a point called "LTB1D1" located in unit "S1" that is connected to a network called "UDH".
