1.3  Using ET 200S Fail-Safe Modules 
Possible Uses of ET 200S with Fail-Safe Modules    
The use of ET 200S with fail-safe modules enables conventional safety engineering designs 
to be replaced with PROFIBUS DP/PROFINET IO components. This includes the 
replacement of switching devices for emergency STOP, protective door monitors, two-hand 
operation, etc. 
Use in F-Systems   
Fail-safe ET 200S modules can be used: 
●  In the S7 Distributed Safety F-system with the 
S7 Distributed Safety 
optional package 
V5.2 or higher 
●  In the S7 F/FH Systems with the 
S7 F Systems
optional package version V5.2 SP 3 or 
higher 
●  To interface ET 200S fail-safe modules to PROFIBUS DP with Distributed Safety or S7 
F/FH systems, you need: 
–  ET 200S fail-safe modules 
–  F-CPU 
– 
STEP 7
 V5.3 SP3 or higher 
–  IM151-1 DP HIGH FEATURE interface module 
– 
S7 Distributed Safety 
V5.2 or higher (for the order numbers specified in the "Preface":
 
F Configuration Pack
 Version V5.5 SP5 or higher) 
The 
F Configuration Pack 
 can be obtained on the Internet 
(
