Siemens 6ES7416-2XN05-0AB0 SIMATIC S7-400 CPU

Siemens SIMATIC S7-400 CPU 416-2, part number 6ES7416-2XN05-0AB0, is a central processing unit for the S7-400 automation system that packs 5.6 MB of working memory (2.8 MB code, 2.8 MB data) and two on-board communication interfaces: MPI/DP at 12 Mbit/s and PROFIBUS DP. This CPU is designed for reliable mid-range control tasks in rack-based S7-400 installations, with native support for PG/OP communication and S7 basic communication over both MPI/DP and DP networks. The 416-2 variant provides standard S7-400 processing capabilities while enabling connections to a DP fieldbus for I/O modules and to MPI networks for supervisory or partner PLCs. With its two communication interfaces, it can coordinate across distributed controllers and devices in industrial environments, supporting deterministic execution, program and data memory separation, and integration with other Siemens automation components. The device aligns with Siemens' S7-400 CPU specifications and serves as a compatible replacement part within the CPU 416-2 family for installations requiring the 6ES7416-2XN05-0AB0 configuration.
