Fail-safe digital input modules are suitable for connecting
The modules are implemented centrally with SIMATIC S7-31xF-2 DP, and in the ET 200M distributed I/O module in combination with SIMATIC IM 151-7 F-CPU, S7-31xF-2 DP, S7-416F-2 and S7-400F/FH. They can also be used in non-safety-relevant standard mode. In this case, they behave like standard S7-300 modules.
