SIMATIC Factory Safety

Controllers

The safety SIMATIC controllers are based on a standard CPU whose operating system and hardware components were expanded to include a variety of different protective mechanisms. They can be used as standard CPUs.

Safety-related tasks can thus be economically implemented using only one CPU or as always in separate design.

The safety CPUs can be expanded with ET 200M, ET 200S, ET 200pro (IP67) signal moduls and/or digital block peripheral device ET 200eco (IP67).

PROFIBUS or PROFINET with PROFIsafe profile is used for communication between two safety CPUs or between a safety CPU and the safety I/O allocated to it.

Overview of further highlights

• Programming with STEP 7 and S7 Distributed Safety in FBD and LAD
  
  

  -	Library with TÜV-certified function blocks

  
  
• The coexistence of standard and safety programs in one CPU is possible
  
  

  -	Modifications to the standard program have no effect on the existing signatures of the safety-relevant program section

  
  
• The safety SIMATIC controllers are in compliance with the highest safety level:
  
  

  -	IEC 61508 and EN 62061 (up to SIL 3)
  -	EN 954-1 (up to Cat. 4)
  -	NFPA 79 - 2002 and NFPA 85
  -	UL 1998, UL 508, UL 991
  -	TÜV-certificate no: Z10 05 08 20411 002
