The CPU 416F-2 and the CPU 416F-3 PN/DP are high-performance CPUs of the SIMATIC S7-400. They allow a fail-safe automation system to be constructed for plants with increased safety requirements.

The integrated PROFIBUS DP interfaces of CPU 416F-2 support direct connection to the PROFIBUS DP fieldbus as a master or as a slave.

Another DP master system can be connected in the case of the CPU 416F-3 PN/DP through the IF 964-DP interface module.

The integrated PROFINET interface of the CPU 416F-3 PN/DP implements switch functionality by using the ERTEC 400 ASIC. This forms the basis for provision of 2 externally accessible PROFINET ports. This means that apart from hierarchic network topologies, line structures can also be implemented with the new S7-400 controllers.

Note:
Only interface module 6ES7964-2AA04-0AB0 can be used.

Fail-safe I/O modules can be connected to all integrated interfaces, to IF 964-DP and/or through communication modules (CP443-5 Ext. and CP443-1 Advanced). Safety-related communication is performed over PROFIBUS DP with the PROFIsafe profile.
