F-I/O
Group designation for fail-safe inputs and outputs available in
SIMATIC S7
for the integration
in the S7 Distributed Safety and S7 F/FH Systems fail-safe systems. Available F-I/O
modules:
● Fail-safe I/O module for ET 200eco
● S7-300 fail-safe signal modules (F-SMs)
● Fail-safe modules for ET 200S
● Fail-safe DP standard slaves (for S7 Distributed Safety only)
● fail-safe PA field devices
● fail-safe IO devices

Interconnecting
Refers to the opening of a new voltage group by a power module.
This allows individual grouping of sensor and load supplies.
IO controller
-> PROFINET IO controller
IO device
-> PROFINET IO device
Module fault
Module faults can be external faults (e.g. missing load voltage) or internal faults (e.g.
processor failure). Internal faults always require module replacement.
Monitoring time
-> PROFIsafe monitoring time
Motor starter (MS)
Motor starter is a generic term for direct and reversing starters. Motor starters are used to
determine motor startup and the direction of rotation.
