Product Introduction and Key Specifications
Siemens SIMATIC S7-400 CPU 414-2 DP, order code 6ES7414-2XG02-0AB0, is a central processing unit for the S7-400 rack. It carries 128 KB working memory—enough for mid-size control programs in process or factory automation—and integrates both a multi-point MPI interface and a PROFIBUS-DP interface on the module. The PROFIBUS-DP interface allows direct connection to remote I/O, drives, and other field devices over a deterministic fieldbus, making this CPU a fit for distributed control cabinets in chemical plants, power stations, or large production lines where PROFIBUS is the backbone. At 0.54 kg, the module slots into a standard S7-400 rack. Working memory is 128 KB.
This CPU is the correct part for a like-for-like replacement or spare in S7-400 systems.
