Diagnostics alarms
A diagnostics alarm is output for each diagnostics event and the DIAG LED flashes on the
module. The diagnostics alarms can, for example, be read from 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.

H
The module has detected that the maximum
permitted module temperature has been
exceeded. All channels of the module are
switched to high resistance. The module is
then restarted.
Correct the process wiring
High limit violated

Incorrect parameter assignment.
Correct the parameter assignment

H
Module is defective.
Replace the module.

Firmware update in progress or update has
been canceled.
The module does not read out any process
values or substitute values in this state.
•
Wait for firmware update.
•
Restart the firmware update.
1
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
adjacent channel. The load groups do not have an effect on each other in the case of a short-circuit.
2
If the short-circuit persists, the module heats up. This may trigger temperature monitoring with overtemperature
diagnostic interrupt.
