Siemens 6ES7414-3XM07-0AB0 S7-400 CPU 414-3 4MB 3-Interface Programmable Logic Controller

The Siemens 6ES7414-3XM07-0AB0 is a SIMATIC S7-400 CPU 414-3 central processing unit with 4 MB of work memory (2 MB code, 2 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, 2 integrated DP masters, and multicomputing with up to 4 CPUs in one rack.

Selection Notes

With 2 integrated PROFIBUS DP masters plus a third slot for a plug-in interface module, this CPU handles a DP master role, a second fieldbus segment, and a dedicated communication module at the same time, useful when a machine needs both PROFIBUS DP I/O and a separate network interface without an external IM rack. The 4 MB work memory (2 MB code / 2 MB data) and 6,000 max data blocks give it more program headroom than a smaller-memory CPU in the same rack family, and multicomputing lets up to 4 of this CPU run together in one UR1/UR2 rack for segmented control tasks. For decentralized I/O over Ethernet without a plug-in CP, a CPU with a native PROFINET interface is the better fit.

Applications

Mid-to-large PLC control tasks in S7-400 racks that need large program memory, more than one PROFIBUS DP segment, or multicomputing across several CPUs in the same rack.
