SIEMENS SIPLUS S7-300 SM 326 – Safety Integrated Overview
Overview
- Digital inputs for the fail-safe SIPLUS S7 systems
- For connecting:
- Switches and 2-wire proximity switches
- Sensors according to NAMUR and mechanical contacts, also for signals from hazardous areas
- With integral safety functions for fail-safe operation
- Can be used in fail-safe operation
- Centrally: with S7-31xF-2 DP
- Distributed in ET 200M: With SIMATIC IM 151-7 F-CPU, S7-31xF-2 DP, S7-416F-2 and S7-400F/FH
- In standard operation can be used in the same way as S7-300 modules
Note:
SIPLUS extreme products are based on SIMATIC standard products. The contents listed here were taken from the respective standard products. SIPLUS extreme-specific information was added.
Fail-safe digital input modules are suitable for connecting
- Switches and 2-wire proximity switches (BEROs)
- Sensors according to NAMUR and mechanical contacts, also for signals from hazardous areas
The modules are implemented centrally with SIMATIC S7-31xF-2 DP and in the ET 200M distributed I/O station 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 and then respond like standard S7-300 modules.
