Which node can I use to conncet the BACKHOFF-CX5130

The use of this brand PLC document is not much, I do not know how to establish communication with it :smiling_face_with_tear:

Beckhoff PLCs usually support the TwinCAT protocol.

I have not used these but there are some contrib nodes in the library that provide this capability: Library - Node-RED

This one appears well written: node-red-contrib-ads-client (node) - Node-RED

Thank youļ¼ŒI'll check it
