Front connector versions
Use the 40-pin front connector to wire the fail-safe signal modules. The 40-pin or 20-pin front
connector is available in three versions:
●
Cage-clamp technology
●
Screw-type technology
●
Fast Connect technology
For order numbers, see chapter "Accessories and Order Numbers (Page 319)".
For information about cables which may be used to wire the 40-pin front connector, refer to
the
S7-300, CPU 31xC and CPU 31x: Installation manual.

Replacing Fail-Safe Signal Modules
Inserting and removing F-SMs in standard mode
Fail-safe signal modules can be inserted and removed at the S7-300 and ET 200M similar to
any standard signal module.
An ET 200M configuration with
active bus modules supports hot-swapping of the F-SMs
during operation of ET 200M.
Inserting and removing F-SMs in safety mode
Fail-safe signal modules can be inserted and removed at the S7-300 and ET 200M similar to
any standard signal module.
An ET 200M configuration with
active bus modules supports hot-swapping of the F-SMs. A
special bus module is required to interconnect a safety protector with the backplane bus
(order no. see chapter "Accessories and Order Numbers (Page 319)").
Any module replacement generates an error in safety-oriented communication between the
F-CPU and the replaced F-SM when operating in safety mode, regardless of whether or not
active bus modules are being used.
For more information regarding the effects of communication errors, refer to the
S7 Distributed Safety Configuring and Programming or S7 F/FH Systems Configuring and
Programming manual.
WARNING
The safety protector may not be inserted or removed while the system is in operation! (Any
insertion or removal would inevitably lead to failure of the ET 200M.)
Observe the address settings when replacing modules in safety mode
Make sure that the address switch (DIP switch) on the rear panel of the replaced F-SM has
the same setting!
