OPC Server Overview

DM_OPC_SERVER is a DM which acts as a second server layer on top of the DB slot server. This DM may be accessed:

·      programmatically

·      using the custom OPC client (OPC Client.exe) supplied with iDX in iDX Install Directory \utils\OPC

·      using DM_OPC_CLIENT from another DB

Since it acts as a layer over the DB slot server, it does not have a configuration file.

The only registry entry that can be edited is OPC_Trace which turns on(1) or off(0) tracing of OPC calls to a debug file.
