Hi All,
I am trying to test the Modbus communication with our UR10 in a bare minimum setup first but I have not been able to yes. Here is what I have tried so far:
- Connected the robot and a pc to the same switch
- Run open mod sim on the PC and connect it. I open the coil status window which by default shows all coils are set to 0
- I turn off firewall and use another computer to make sure I can ping the PC
- On UR teach pendant I add a new modbus unit with IP of the PC
- I add a digital output signal to this unit
- I create a simple program which sets that digital output to High
- I run the program expecting to see the value at coil 00001 to change from 0 to 1 but I see no change
- After about a minute I see the following error message (please see screenshot attached) which refers to code 0 but I am unable to find what code 0 means
Could anyone help me troubleshoot this or give me suggestions on how to create a minimal Modbus setup to test?
Thank you!
