The fail-safe modules of the SIMATIC S7-1200 permit the implementation of safety-related application requirements integrated into the overall automation. The safety functions required for fail-safe operation are integrated in the modules. Communication with the failsafe SIMATIC S7 CPUs is performed by means of PROFIsafe mechanisms.
The modules can be operated exclusively in the central system.
