UR Dashboard P2000 PLC

Trying to connect UR5e/UR10e/UR20 to a PLC for Dashboard commands. Already have full Ethernet IP registers working and in operations. Dashboard commands are needed for remote fault recovery and other tasks.

PLC: Productivity P2000
Dashboard Message Return is working with TCP using port 29999 as indicated in the documentation.
Testing with a PC Socket Test 3 works.

Commands are not functioning and need additional information on data formatting. Message is ASCII, termination is ‘\n’.

  1. Any leading characters or commands before the message?
  2. Is there a desired data length for the message or is it flexible based upon the ASCII message length.
  3. Terminating Character details, I believe this is where the issue lies.

I am not 100% sure how that PLC works, but in some other posts about Siemens PLC you can see it is needed to add $L at the start and at the end of the command:
