Diagnostics alarms

A diagnostics alarm is output for each diagnostics event and the DIAG LED on the
module flashes. 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.

Remedy
Wait for firmware update
•
Restart the firmware update
•
Correct the process wiring
Use a different actuator type or wire
differently, e.g. use cables with a larger
cross-section
Connect the cable
Disable diagnostics
•
Connect a resistor to the actuator
•
contacts in the load resistance range
Correct the parameter assignment
Check supply voltage L+
•
on the BaseUnit
Check BaseUnit type
