2.1 Configuring ET 200S with Fail-Safe Modules
Introduction
The ET 200S distributed I/O systems support configurations with standard and fail-safe
modules. This chapter presents an example configuration.
Configuration example of ET 200S with Fail-Safe Modules
In the following figure you will find a configuration example using standard and fail-safe
modules in an ET 200S. You
can
divide and install the modules in fail-safe and standard
potential groups. A new potential group always begins with a power module.

WARNING
If the implemented standard module has electrical isolation of ≥ 60 VAC / 75 VDC and test
voltage of 500 VDC, it is possible to mix F-DI-/F-DO modules and standard DI-/DO-/FM
modules within one potential group as of the following MLFBs for the SIL3/Category 4/PLe:
6ES7138-4CF03-0AB0
6ES7138-4CF42-0AB0
3RK1903-3BA02
6ES7138-4FA04-0AB0
6ES7138-4FC01-0AB0
6ES7138-4FB03-0AB0
6ES7 138-4FR00-0AA0
For the predecessor modules, you can achieve SIL2/Category 3/PLd with a mix of F-DI-/F-
DO modules and standard DI-DO modules.
