SIMATIC Factory Safety

I/O

The safety modules of ET 200M, ET 200S, ET 200pro (IP67) and/or the digital block peripheral device ET 200eco (IP67) are used for the distributed expansion of safety controllers. In a centralized configuration, the S7-300F CPU can be expanded with safety modules of ET 200M.

All safety modules can diagnose internal and external faults and are internally redundant. They have their own self-tests and fulfill the obtaining safety requirements. In addition, "safety" and "non safety" I/O modules can be combined in an ET 200M/ET 200S/ ET 200pro station. Both the safety and the standard I/O modules are interfaced via a fieldbus system, i.e. PROFIBUS with PROFIsafe profile.

The safety modules of ET 200S and ET 200pro can also be connected to a PROFINET network via PROFINET interface modules.

The safety SIMATIC I/Os meet the highest safety requirements:

IEC 61508, IEC 61511 and EN 62061 (up to SIL 3)
EN 954-1 (up to Category 4)
NFPA 79 - 2002 and NFPA 85
UL1998, UL 508, UL 991
TÜV certificate no: Z10 05 08 20411 002
