Replacing a Fail-Safe I/O Module

Replacing a Fail-Safe I/O module During Operation
A fail-safe I/O module can be replaced in exactly the same way as a standard
ET 200eco I/O module (turn off the power to the I/O module, remove the module,
connect up the new I/O module).
Note
Note that replacing a fail-safe ET 200eco I/O module during operation causes a
communication error on the F-CPU.
You must acknowledge the communication error in your safety program (for the
response of the F-system after communication errors, output of a fail-safe value
and user acknowledgment, refer to the manual S7 Distributed Safety,
Configuration and Programming or Programmable Controllers S7 F/FH Systems).
Caution
!
Turn off the load power supply (2L+) before dismantling the terminal block. When
the terminal block is dismantled, degree of protection IP 65, IP 66 or IP 67 no
longer applies.
Remember to Set the PROFIsafe Address
When replacing a fail-safe I/O module, make sure that the address switch (DIP
switch) setting on the modules match (for information on the PROFIsafe address
setting, see Chapter 4).
Note
Please refer to the information on dismantling and replacing the I/O module and
the terminal block in the ET 200eco Distributed I/O Station manual.
