Generally Applicable Information on Diagnostics
For information on diagnostics that affects all fail-safe modules (such as readout of
diagnostic functions; passivation of channels) see this manual in

Possible Causes
Inserted module does not match
configuration
Faulty parameter assignment
PROFIsafe address set incorrectly in
the F-module
No supply voltage or supply voltage
is too low
Error in communication between F-
CPU and module due to defective
PROFIBUS connection or higher than
permissible EMI, for example
PROFIsafe monitoring time set too
low
Configuration of the F-module does
not match safety program
Faulty process signal
Defective sensor
Short circuit between unconnected
sensor cable and the sensor supply
cable
Wire break in connected sensor cable
or the sensor supply cable
Assigned discrepancy time too short
manual.
.
Corrective Measures
Correct configuration (compare actual and
preset configuration)
Check communication paths
Correct configuration
Check whether the PROFIsafe address on
the module matches the configuration in
HW Config
Check the supply voltage on the
interconnected PM
Check module for correct contact
Check the PROFIBUS/PROFINET
connection
Eliminate the interference
Set a greater value for the "F monitoring
time" parameter for the module in
HW Config
Generate safety program again; then load
configuration and safety program into F-
CPU again
Check process signal, replace sensor if
necessary
Eliminate short circuit
Eliminate broken wire
Check the assigned discrepancy time
Once the fault is eliminated, the F-module
must be reintegrated in the safety
program
