Register Communication Error (Bus Init)

What does 5 (Argument: n*) mean?

A register communication error occurred during the internal data bus initialization process for the (n+1)th process data module. This suggests a problem with the module's ability to communicate its registers during startup, which is essential for proper system configuration and operation. Modules that do not provide any data are ignored.

• A faulty (n+1)th process data module preventing successful register communication.
• Incorrect addressing or corrupted internal configuration data within the (n+1)th module.
• Intermittent connection of the (n+1)th module during system initialization.

2. 2

   Replace the (n+1)th process data module.

3. 3
