CPU 416-2, CPU 416-3 and CPU 416-3 PN/DP are powerful SIMATIC S7-400 CPUs.

The integrated PROFIBUS DP interfaces in the CPU 416-2 and CPU 416-3 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 416-3 and CPU 416-3 PN/DP using the IF 964-DP interface module.

The integrated PROFINET interface of the CPU 416-3 PN/DP implements switch functionality. This forms the basis for providing 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 the interface module 6ES7 964-2AA04-0AB0 can be used.
