Rslinx Classic 3.9 Does not Show DDE/OPC tags

Mray · Apr 9, 2020

Hi,
I am gonna use Rslinx classic 3.9 to copy DDE/OPC tags' link from CompactLogix CPU to Excel through Ethernet/IP but It does not show any of them in Copy DDE/OPC link window. The window is empty with the title of:

RSLinx OPC Server (Node:<Local>)\MyPLC\Online

I have configured DDE/OPC as:
Station (decimal): 49
Remote: Remote ControlNet

The free version bundled with say Studio 5000 doesn't have that capability, you need the OEM version:

It is pain in neck to call and explain them. but at least it is my last bullet.

When you set up your OPC topic in RSlinx, did you browse to the controller? Sometimes folks select the comm card instead of the CPU, something to check.

Yes I chose the CPU. I just right click on CPU and choose Configure New DDE/OPC

Have you ever tried opc with this version of rslnix,
You need rslinx gateway for OPC to work.

you need the golden locked on the topic, like this:

I'd delete it and create a new topic.

and have you checked the target PLC to see if there are any tags there

I just noticed. How can I have golden lock on it? There is not any explanation on that thread.
