URSim driver

This driver allows the communication between Simumatik and URSim to connect to exchange I/O variables and axis values in degrees.


Aside from the common parameters described in the communication_driver docs, this driver includes:

  • host: IP address of the UR robot. Default = ''
  • port: Port number used by the UR robot. Default = 30004
  • frequency: Refreshing time value. Default = 125

Setup data

The setup data will give values to the parameters required and will specify the I/O variables info.

    "parameters": {
        "host": "localhost", 
        "port": 30004,
        "frequency": 125,
    "variables": {
        "inputs": {
            "datatype": "byte", 
            "size": 1,
            "operation": "write"
        "outputs": {
            "datatype": "byte", 
            "size": 2, 
            "operation": "read"


The setup_params in the generic PLC components for ur_driver will need the following format:

{"host": "localhost", "port": 30004, "frequency": 125}
