Hello, I am trying to connect MODBUS to a UR5 robot. The ethernet keeps staying yellow, and the MODBUS section turn green on the robot, but it will turn green even if nothing is connected to it. The IP is set to its correct value.
Ethernet turns yellow? Are you talking about the EtherNet/IP fieldbus adapter next to MODBUS? EtherNet/IP is a communication protocol like MODBUS, and you don’t enable it unless you need it.
A lot of people mix up TCP/IP (the network connection) and EtherNet/IP.
After disabling it you can test the MODBUS further. And ask here if you need anything.
