Interrupts

The DQ 8x24VDC/2A 8xM12 IO-Link digital output module supports diagnostic interrupts.

Diagnostic interrupt

The digital output module generates a diagnostic interrupt at the following events:

• Short-circuit of outputs to ground

• Load voltage 2L+ missing or too low

5.3

Diagnostics alarms

For each diagnostic event, a diagnostics alarm is issued and the LED DIAG flashes red on the

digital output module. You can read out the diagnostics alarms, for example, from the status

of the IO-Link master. You can evaluate the error codes with the user program.
