Maintenance events

Maintenance event for IO-Link master
All IO-Link events of the type Warning generated by the IO-Link device or port are mapped to
the PROFINET diagnostics alarm of the type "Maintenance" of the assigned submodule. The
aim is the early detection and elimination of potential faults.
For the IO-Link master, maintenance events signal to the user when a network component
must be checked or replaced.
Example of displaying the IO-Link event codes:
An IO-Link device generates EventCode 0x8CA0
The channel diagnostics results from the event code:
• PROFINET channel diagnostics type: Maintenance CET: 0x9501
Maintenance "IO-Link Device Diagnostics - Page 2, Ambient light interference", generated
from the IO-Link event code 0x8CA0
Maintenance event for DIQ and for IO-Link master
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 early as possible.
The I/O device signals a maintenance event to the higher-level diagnostic system on the
following event:
