1. 1

   Inspect all network cables and connectors (e.g., Ethernet, Sercos, Profinet) connected to the Bosch Rexroth motion control system and the associated PLC for physical damage, proper routing, and secure connections.

2. 2

   Verify the network configuration parameters (e.g., IP addresses, subnet masks, gateway, device IDs, communication protocols) on both the Bosch Rexroth motion controller and the PLC against the documented system setup.

3. 3

   Measure the supply voltage at the input terminals of the Bosch Rexroth motion controller, the PLC, and any intermediate network switches to ensure they are within the manufacturer's specified range.

4. 4

   Check all diagnostic LEDs and status messages on the Bosch Rexroth motion controller, the PLC, and active network components for specific error indications related to network communication.

5. 5

   Verify the integrity of the PLC application program, specifically communication blocks and their setup within the APS, by comparing it to a known good backup if available.
