Connect an Allen Bradley ControlLogix plc to LabView using the OPC Toolkit

[MaijkelHartman]

Greetings,

I am trying to connect multiple Allen Bradley L5581 PLCs to a desktop computer running Labview. A LabView OPC server (from the OPC toolkit) is running on the desktop.

The problem I have now is that I am at a complete loss how to configure the AB plcs as OPC client. It is my understanding that the PLCs only communicate with an OPC server set up with RSLinx, but I wish to avoid this due to licensing costs.

My question is:  "Is it possible to set up an Allen Bradley plc as a OPC client for a Labview OPC server?" Does anyone have literature/example code an how to go about this?

Have you checked out this webpage? It demonstrates the process from the NI server side of things https://knowledge.ni.com/KnowledgeArticleDetails?id=kA03q000000x0MPCAY&l=en-US

Once you download the program onto the PLC and add the PLC to the NI OPC server, you should be able to see your tags in the NI OPC. If I recall correctly, I don't think there's anything else you need to configure in the PLC software
