Access to events
Some of the IO-Link sensors forward events that occur to the master. These events may be items of
information, warnings or error messages, e.g. short circuit or overheating.
The IO-Link master reports these events by setting the Device Diag bit. Further information on the events
can be read via the CoE directory or the DiagHistory tab.
Fig. 41: DiagHistory tab
The events are arranged according to type (information, warning, error), flag, occurrence of the event (time
stamp) and message (port number & event code).
The meaning of the individual messages can be taken from the vendor documentation. The IO-Link device
can be directly allocated on the basis of the port number. The events occurring can be managed using the
various buttons.
