2.1 Configuring ET 200S with Fail-Safe Modules
ET 200S Distributed I/O System - Fail-Safe Modules

Configuration Rules for Fail-Safe Potential Groups
The "Assigning Power Modules to Electronic Modules/Motor Starters and Safety Class" table
lists all the fail-safe and standard power modules and electronic modules you can implement
in a potential group.
Configuration with Fail-Safe Motor Starters and Frequency Converters
Use a PM-D F DC24V PROFIsafe for the selective shutdown of:
● Fail-safe motor starters (F-MS) F-DS1e-x, F-RS1e-x
● SINAMICS fail-safe frequency converters (F-FU) with ICU24(F)
● Fail-safe F-CM connection multipliers
● PM-D F X1 fail-safe power/expansion modules.
The PM-D F DC24V PROFIsafe cannot supply other motor starters (such as DS1-x/RS1-x,
DS1e-x/RS1e-x, DSS1e-x)!
The fail-safe motor starters can be expanded:
● Up to safety class SIL3/Category 4/PLe with the Brake Control xB1, xB2 expansion
modules
● Up to safety class SIL2/Category 3/PLd with the Brake Control xB3, xB4 expansion
modules
Example of a Configuration with Fail-safe Motor Starters
The figure below shows an example of an ET 200S configuration with two fail-safe potential
groups. The first potential group contains fail-safe motor starters and a connection multiplier.
This configuration achieves safety class SIL3/Category 4/PLe.
