F-I/O is a group designation for fail-safe inputs and outputs available in
SIMATIC S7 for integration in S7 Distributed Safety and S7 F/FH
systems. The following F-I/O modules are available:
Fail-safe ET 200eco I/O module
•
S7-300 fail-safe signal modules (F-SMs)
•
ET 200S fail-safe module
•
Fail-safe DP standard slaves (for S7 Distributed Safety only)
•
-> PROFIsafe monitoring time
-> Fail-safe systems
I/O module faults can be external faults (for example, missing load
voltage) or internal faults (for example, processor failure). An internal
fault always requires I/O module replacement.
-> PROFIsafe monitoring time
A nonequivalent -> sensor is a reversing switch that is connected to two
inputs of an -> F-I/O (via 2 channels) in -> fail-safe systems (for -> 1oo2
evaluation of sensor signals).
Parameter assignment via PROFIBUS DP: Transfer of slave parameters
from the DP master to the DP slave
Parameter assignment of modules: Setting the module behavior using
the STEP 7 configuration software
