Siemens 6ES7416-3XS07-0AB0 SIMATIC S7-400 CPU 416-3 16MB 3-Interface Programmable Logic Controller

The Siemens 6ES7416-3XS07-0AB0 is a SIMATIC S7-400 CPU 416-3 central processing unit with 16 MB of work memory (8 MB code, 8 MB data) and three interfaces: MPI/DP at 12 Mbit/s, a second PROFIBUS DP port, and a third slot for a plug-in IFM module. It supports up to 21 expansion units and 2 integrated DP masters.

Selection Notes

Two integrated PROFIBUS DP masters plus a third slot for a plug-in interface module let this CPU run a DP master segment, a second fieldbus, and a dedicated communication module together, which the 2-interface 416 CPU in the same family cannot do. 16 MB of work memory doubles the program headroom of that 2-interface CPU. Where the application needs a native Ethernet/PROFINET port instead of a plug-in IFM slot, the PN/DP variant in the same 416-3 family is the closer match.

Applications

S7-400 control tasks needing more than one PROFIBUS DP segment or a dedicated communication module slot, with 16 MB of program and data memory for mid-to-large logic.
