Siemens 6ES7 416-2XK04-0AB0 CPU Processing Unit

Siemens 6ES7 416-2XK04-0AB0 CPU Processing Unit is a SIMATIC S7-400 central processing unit (CPU 416-2 DP) with firmware version V4.x, designed for deterministic industrial automation tasks. It provides 1.4 MB of code memory and 1.4 MB of data memory, for a total of 2.8 MB of work memory, enabling complex control logic and data handling. The CPU delivers a compact execution time of 0.04 ms per 1,000 instructions and includes 16 KB of digital I/O; it supports 64 connections and offers one DP/MPI port and one DP port for flexible network communications. It supports direct data exchange (send/receive) between devices and provides constant bus cycle times with isochronous processing, routing, and multicomputing capabilities for coordinated control across multiple CPUs and DP devices. This model is commonly used in PCS 7 environments and other SIMATIC S7-400 installations, where reliable real-time control and scalable communication are required.
