PROFIBUS/PROFINET: Bus configuration changed (slave/device)

What does 380502 mean?

This alarm signals that the PROFIBUS/PROFINET bus configuration has changed, either due to initial commissioning or the recognition of a new slave/device on the bus. While not an error in itself, the new settings will only become active after a system restart. This requires a controlled restart to ensure the new configuration is properly loaded and the system operates as intended, avoiding potential communication inconsistencies.

Complete Troubleshooting Guide

1. 1

   Perform a control system OFF-ON cycle (power cycle) to activate the new bus configuration.
