Error Codes and Events
When an event occurs, the device signals the presence of the event to the
master. The master then reads out the event. Events can be error messages and
warnings/maintenance data. Error messages are transmitted from the device to
the controller via the IO-Link master. The transmission of device parameters
or events occurs independently from the cyclic transmission of process data.
