Connection between PLC and device could not be established

What does 11006 mean?

The PROFINET connection between the PLC and the specified device ({Name}) could not be established within the configured timeout period. This can be caused by an excessively low bus timeout setting, a mismatch between the controller and PLC configurations, or a defective PROFINET device, preventing proper operation.

1. 1

   Increase the 'Bus timeout' parameter setting in the PROFINET configuration on the robot controller (refer to Page 18) to allow more time for connection.

2. 2

   Verify that the PROFINET device configuration in WorkVisual on the robot controller matches the PROFINET configuration loaded in the PLC for device {Name}.

3. 3

   Perform diagnostics on the PROFINET device {Name} itself, potentially replacing it if internal faults are detected.
