Extended Modbus OPC Server

Operation and Reference

Having a .MIF file is very handy. Connecting the MIF file to a device in the OPC tag

database will create the groups and signals automatically. This will save a tremendous

amount of time compared to creating them manually.

In the case of generic Modbus devices such as ABB Commander series instruments, you

have to create the groups and tags manually and should define their properties. Refer to

the Standard Modbus section of this chapter.

Timeout: Timeout value in ms is the time for which the OPC server tries to reestablish

communication with the device in the case of a communication failure. The default value

of 1000 ms should not need to be changed.
