Siemens: SIMATIC S7-1200 CPU and I/O modules

Maintaining an existing control system starts with the complete Siemens order number. The examples distinguish a compact CPU from a digital expansion module. Hardware identification, firmware and the engineering project version belong in the technical review.

Important differences before ordering

CPU 1214C and SM 1223 are different components. Do not confuse these S7-1200 references with S7-1200 G2. A generation change requires a separate review of hardware, program and expansion modules.

This selection is not a complete catalogue or a sales ranking. Technical details support identification; current manufacturer documentation and approval for your application remain decisive.
