IO-Link Event Log
This section provides information about IO-Link events, event data structure, and a list
of device-level IO-Link events.
To access the IO-Link device event log, see Event Log View.
For IO-Link device event codes, see the IO-Link Interface and System Specification at
io-link.com, and the documentation for the device for more

Use CIP Messages to Retrieve the IO-Link Event Log
To retrieve the IO-Link event log, follow the definition of the Event Log object
(class 0x41) that is defined in the CIP Specification Volume 1 and Volume 7C.
Following table defines the format of each event log entry.
Byte Offset | Bit Offset | Parameter |
|---|---|---|
0 | 0…2 | Reserved |
3 | Event Location (always 1 for IO-Link master module) | |
4…5 | Event Type | |
6…7 | Event Mode | |
1…2 | — | Event Code |
3…10 | — | Timestamp (only exists when IO-Link Event Timestamp is
enabled) |
You can use either attribute 14 or 22 to retrieve the event log.
To retrieve the Event Log for an IO-Link device, use a CIP message with the following
specifications:
- Communication Path = To IO-Link device
- Instance = 1
