Diagnostic Alarms
Diagnostic alarms originate from the IO-Link master. They indicate events on the IO-Link
master or its ports. The following values are set in the “Event Qualifier”:
TYPE = 2 (Warning) or 3 (Error)
MODE = 2 (Event disappears) or 3 (Event appears)
SOURCE = 1 (Master/local)
The IO-Link master sends this event to the IO controller as a diagnostic alarm. The value
of “Channel Error (PROFINET)” is 0x9502.
The following table lists the numbers of the IO-Link master diagnostic alarms.
