Generally Applicable Information on Diagnostics
For information on diagnostics that pertains to all fail-safe modules (for example, for reading
out diagnostic functions, or passivating channels), refer to the
manual.

Fault Possible Causes
Detection
Always Internal module fault
has occurred
Always Inserted module does
not match
configuration; incorrect
parameter assignment
PROFIsafe address set
incorrectly in the F-
module
Always Supply voltage not
available or too low
(e.g. voltage dip on F-
module, this can also
be caused, among
other things, by a
short-circuit on the
P1/P2 buses)
Always 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
Always Switching frequency
exceeded
Corrective Measures
Replace module
Correct the configuration (compare actual
and preset configuration), and check
communication paths. Correct parameter
assignment.
Check whether the PROFIsafe address
on the module matches the configuration
HW Config
in
Check module for correct contact
Test PROFIBUS/PROFINET connection.
Correct faults
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
Reduce the switching frequency
