Hi,
I briefly describe the problem encountered:
- Ping : ok
- Connect : ok
- Get Position : Error

I have installed RoboDK version 5.9.0
This is the error log:

I don't have access to the decompiled driver, so I can't give the best advice, but you could try manually installing/setting up pymodbus 3.0.2.

Alternatively, some solutions in this thread might be helpful:

Pymodbus should be installed by default with the Python embedded version. If you use your custom version of Python, then make sure to install the pymodbus module.

Make sure to connect to the correct physical port on the controller with modbus connection (there is only 1 that allows a modbus connection).
