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.

The channels 0 and 1 or 2 and 3 each form a load group. Within a load group, a short-circuit can have an effect on the
1
adjacent channel. The load groups do not have an effect on each other in the case of a short-circuit.
If the short-circuit persists, the module heats up. This may trigger temperature monitoring with excess temperature

Meaning
Short-circuit of the actuator supply
The module has detected that the maxi-
mum permitted module temperature has
been exceeded. All channels of the mod-
ule are switched to high resistance. The
module is then restarted.
