CPU 414-2, CPU 414-3 and CPU 414-3 PN/DP are designed for high demands in the mid-level performance range. They meet higher demands for program scope and instruction processing speed.

The integrated PROFIBUS DP ports in the CPU 414-2 and CPU 414-3 make it possible to connect directly to the PROFIBUS DP fieldbus as a master or slave.

An additional DP master system can be connected to the CPU 414-3 and CPU 414-3 PN/DP using the IF 964-DP interface module.

For the PROFINET interface of the CPU 414-3 PN/DP, the switch functionality permits the formation of two 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 the 6ES7964-2AA04-0AB0 interface module may be used.
