Properties of system diagnostics

Introduction
In the SIMATIC environment, the term "system diagnostics" refers to diagnostics of devices
and modules.
All SIMATIC products have integrated diagnostic functions that you can use to detect and
remedy faults. The components automatically flag a potential fault in the operation and
provide detailed information. You can minimize unscheduled standstill times with plant-wide
diagnostics.
The SIMATIC automation system monitors the following states in the running plant:
● Device failure/recovery
● Insert/remove event
● Module fault
● I/O access error
● Channel fault
● Parameter assignment error
● Failure of the external auxiliary voltage
