Interrupts

The DQ 4×24VDC/2A HS digital output module supports diagnostic interrupts.
Diagnostic interrupts

Diagnostics alarms

Diagnostics alarms
A diagnostics alarm is output and the DIAG LED flashes on the module for each diagnostics
event. You can read out the diagnostics alarms, for example, in the diagnostics buffer of the
CPU. You can evaluate the error codes with the user program.
Note
You can connect 2 actuators per output.
The diagnostics of the two actuators influence each other in the case of duplicate wiring.
This means that a single short-circuit affects both actuators.
