Technical Note Details:
Problem:
The following error is generated after upgrading RSLinx from 2.0 to 2.1 when
OPC communications are in use between RSView32 and RSLinx Professional.
Client: Could not connect to the OPC Server.
Cause:
RSLinx Professional OPC Server version 2.1 now connects through a in-process
DLL. RSLinx Professional OPC Server version 2.0 connected as a local EXE.
This different connection method prevents RSView32 from communicating to the
OPC server.
