4.1 Overview
Diagnostics options
In case of an error you can determine the current status of your automation system and react
specifically by using the event-related diagnostics and the evaluation of interrupts.
You can use the following options for diagnostics of the PROFIBUS components:
●
Determine the status of the system using the Lifelist in STEP 7.
● Evaluate the module status, error and message texts by using the display of the S7-1500
CPU.
● Run cable diagnostics during operation by means of the diagnostics repeater.
● Evaluate the diagnostics and interrupt behavior in isochronous mode. (Page 70)
● Determine status information for fault localization and fault rectification by using the
DP/PA coupler FDC 157-0 configured as PROFIBUS diagnostics slave.
