Introduction

In this chapter
This chapter contains information about:
● Central and distributed configuration with F-SMs
● Components which can be used for F-SMs in standard mode
● Components which can be used for F-SMs in safety mode
● Options of combining F-SMs and standard modules in the same configuration
Central and distributed configuration
All fail-safe signal modules support operation in standard and safety mode in a central S7-
300 system and in a distributed system with ET 200M distributed I/O devices.
Note
To use the HART function of the SM 336, F-AI 6 x 0/4 ... 20 mA HART analog module
requires distributed implementation in ET 200M.
