6.3 Diagnostic alarms
Diagnostic alarms
Module faults are indicated as diagnostics (module status).
Note
You can connect several actuators per output.
If several actuators are connected to an output, the diagnostics of each actuator affects the
other ones.
This means:
• A wire break is only signaled when several actuators are affected.
• A single short-circuit affects multiple actuators.
Once the fault is eliminated, the F-module must be reintegrated in the safety program. For
additional information on passivation and reintegration of F-I/O, refer to the SIMATIC Safety
– Configuring and Programming
(http://support.automation.siemens.com/WW/view/en/54110126) manual.

Fault Meaning
code
5 An excessively high temperature was
D
measured in the F-module.
6 Possible causes:
D
There is an interrupted cable between
•
the module and actuator.
The channel is not connected (open).
•
A short-circuit exists.
•
16 Parameter errors include:
D
The F-module cannot use the param-
•
eters (unknown, invalid combination,
etc.).
The F-module parameters have not
•
been configured.
Operate the F-module within the speci-
fied temperature range (see Technical
specifications (Page 51))
Once the temperature has been re-
duced and returns to the specified
range, the F-module must be removed
and inserted or the power switched
OFF and ON.

•
Correct the parameter assignment.
Digital output module F-DQ 8x24VDC/2A PPM (6ES7526-2BF00-0AB0)
Remedy
Establish a cable connection.
Disable the wire break detection for
the channel in the parameter as-
signment.
Eliminate the short-circuit.
