11.2 Diagnostics via EtherNet/IP
The module contains the event log object with information on IO-Link events. The con-
troller can read the attributes of the event log object in order to get the “Event Qualifier”
and “Event Code” of an IO-Link event. A CIP instance is assigned to each IO-Link port.
Event Log Object 65 (0x41)
• Instance 0 (class attribute):
The event log object contains information on IO-Link events.
