3.29.3 SM 322; DO 8 x DC 24 V/0.5 A - Behavior
Influence of the operating state and supply voltage on output values
The output values of SM 322; DO 8 x DC 24V/0.5 A are determined by the CPU's operating
state and the module's power supply.

Reaction to power failure
Failure of the power supply to SM 322; DO 8 x DC 24V/0.5 A is always indicated at the
module's SF LED. This information is also available on the module (entry in diagnostics
data.)
Triggering of diagnostics interrupts is determined by the parameter settings (see the next
chapter Interrupts of SM 322; DO 8 x DC 24/0.5 A (Page 182)).
