We have a 2f-140 gripper that we can't connect to. I have tried using the ROS node, the UR5e teach pendant and the Robotiq User Interface. All fail and don't give a clear answer why.

ROS results in this error: AttributeError: 'ModbusIOException' object has no attribute 'getRegister'

With the robotiq user interface, error is the same as https://dof.robotiq.com/discussion/2245/2f-140-error-i-o-coupling-not-connected

Usually the light is red, except when connected to the ur5e, then it is changing between blue and red.

Hope you can help me further!
