Maintenance events
Maintenance events
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
H
(type "Warning")
.
The channel diagnostics results from the event code:
•
PROFINET channel diagnostics type: Maintenance CET: 0x9501
H
, ECET: 0x0CA0
H
.
Maintenance "IO-Link Device Diagnostics - Page 2, Ambient light interference", generated
from the IO-Link event code 0x8CA0
H
.

Process alarm events
Process alarm events
All IO-Link events (event codes) of the Notification type that are generated by the IO-Link
device are mapped to the PROFINET process alarm of the assigned submodule.

code.
The coding of the additional alarm information corresponds to the coding USI = 0x8320
(ProcessAlarmReason).
