  ET 200S Distributed I/O System - Fail-Safe Modules 
78  Installation and Operating Manual, 08/2008, A5E00103686-07 
Diagnostic 
Message 
Fault 
Detection 
Possible Causes  Corrective Measures 
Error in communication 
between F-CPU and 
module, e.g. due to 
defective PROFIBUS 
connection or higher 
than permissible EMI 
Check the PROFIBUS/PROFINET 
connection 
Eliminate the interference 
PROFIsafe monitoring 
time set too low 
Set a greater value for the "F monitoring 
time" parameter for the module in 
HW Config
 
Communication 
error 
Always 
Configuration of the F-
module does not match 
safety program 
Generate safety program again; then load 
configuration and safety program into F-
CPU again 
Safety-related 
shutdown 
Always  Switching frequency 
exceeded 
Reduce the switching frequency or use a 
semiconductor output 
Generally Applicable Information on Diagnostics 
For information on diagnostics that pertains to all fail-safe modules (e.g. for reading out 
diagnostic functions, passivating channels), refer to the 
"Diagnostics" 
 chapter in this 
manual.
