Stop Due to Field Bus Error

Hva betyr 2858 ?

The robot controller has entered a stop state because an error occurred on the field bus. This indicates a general issue preventing normal operation over the PROFIBUS.

• Loss of communication with a critical field bus device (e.g., I/O module, drive).
• Network congestion or packet loss on the field bus.
• Incorrect or missing configuration of a field bus node.
• Physical damage to the field bus cabling or connectors.

1. 1

   Verify the status LED on each field bus node is illuminated green.

2. 2

   Inspect the field bus cable integrity from the controller to the furthest node.

3. 3

   Check the field bus termination resistors at both ends of the bus.

4. 4

   Review the field bus configuration parameters in the controller, specifically the node addresses.

5. 5

   Measure the signal amplitude on the field bus data lines.
