The CPU 414F-3 PN/DP is a CPU for high demands in the mid-level performance range. They meet higher demands for program scope and instruction processing speed. It permits the design of a fail-safe automation system for plants with increased safety requirements.

The integrated PROFIBUS DP interfaces make it possible to connect directly to the PROFIBUS DP fieldbus as a master or slave.

An additional DP master system can be connected via the IF 964-DP interface module.

For the PROFINET interface of the CPU 414F-3 PN/DP, the switch functionality permits the formation of two externally accessible PROFINET ports. In addition to hierarchical network topologies, this also enables the creation of line structures in the new S7-400 controllers.

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