Siemens 6ES7414-2XL07-0AB0 SIMATIC S7-400 CPU 414-2 2MB MPI/DP PROFIBUS DP PLC

The Siemens CPU 414-2 (6ES7414-2XL07-0AB0) is a SIMATIC S7-400 central processing unit with 2 MB of work memory, split 1 MB for program and 1 MB for data, plus two integrated interfaces: a combined MPI/DP port and a dedicated PROFIBUS DP port. Bit and word instructions run in 18.75 ns typical, faster than the 412 line, for programs with larger logic and data footprints.

Selection Notes

Doubled work memory versus the 412-2, 2 MB against 1 MB, and an instruction time nearly 40 percent faster, 18.75 ns instead of 31.25 ns, make this CPU the choice once program size or scan-time budget outgrows the 412 line while keeping the same MPI/DP plus PROFIBUS DP interface pair. The DB range already reaches 6000 blocks, so projects staying below that count gain little from moving further up the family; those with heavier PROFINET or multi-interface requirements need a PN/DP-equipped CPU instead.
