Maintenance events

Triggering of a maintenance event
The PROFINET IO interfaces of the interface module support the diagnostic concept and
maintenance concept in PROFINET IO according to the IEC 61158-6-10 standard. The goal
is to detect and remove potential problems as soon as possible.
For the interface module, maintenance events signal to the user when a network component
must be checked or replaced.
The CPU interrupts user program execution and processes the diagnostic block OB 82. The
event that triggered the maintenance event is entered in the start information of the OB 82.
The interface module signals a maintenance event to the higher-level diagnostic system in
the case of the following events:
