- Description
The Siemens CPU 412-1 (6ES7412-1XJ07-0AB0) is a SIMATIC S7-400 central processing unit with 512 KB of work memory, split 256 KB for program and 256 KB for data, and a single combined MPI/DP interface running at up to 12 Mbit/s. It takes one rack slot and runs bit and word instructions in 31.25 ns typical, making it a baseline choice for single-interface S7-400 stations.

Selection Notes
A single MPI/DP interface means one PROFIBUS DP network or MPI programming connection at a time, which fits stations where the CPU only needs to talk to a programming device and one field network. The 512 KB work memory and 3000-DB limit suit small to mid-size logic; projects with more data blocks, a second dedicated PROFIBUS interface, or higher I/O counts should move up within the S7-400 CPU line rather than push this unit past its 21-expansion-unit and 47-OP connection limits.
