Hi Joe,
I'm trying to achieve the same thing but am having trouble getting any acknowledgement or data on the PLC side.
I have used Modbus Poll on my laptop and was able to connect to the PLC (V700) and read data, as well as the UR5 and read data, but I cannot get the PLC to read from the UR.
At the moment I am just trying to read the digital inputs of the UR, so if you could help with this I would be very appreciative. I'm new to both devices so if you could also outline the correct socket and ports to use that would be awesome. Thanks!
