SIMATIC Safety Integrated comprises a scalable range of safety-related controllers in various designs based on different hardware platforms for all areas of factory automation – from modular controllers and embedded automation products down to PC-based controllers.
Distributed field devices from the ET 200 range are employed as fail-safe I/O. There are versions for the control cabinet or, with a high degree of protection, for cabinet-free use – in modular and in block design. Connection of the I/O is realized by means of PROFIsafe via PROFIBUS and/or PROFINET.
The fail-safe systems are either configured in the TIA Portal using STEP 7 Safety Advanced or as before with STEP 7 and S7 Distributed Safety. The LAD and FBD languages as well as pre-configured, certified blocks are used for programming the safety program.
