Maintenance events

Triggering of a maintenance event
The MultiFieldbus interfaces of the ET 200eco PN M12-L support the diagnostics concept and
maintenance concept in PROFINET according to the IEC 61158-6-10 standard. The goal is to
detect and remove potential problems as soon as possible.
The I/O device signals a maintenance event to the higher-level diagnostic system on the
following event:
