Description

The Siemens 6ES5928-3UA21 (CPU 928A) is a high-performance central processing unit module engineered for use within the SIMATIC S5-135U and S5-155U programmable logic controller systems. This module is specifically designed to support multi-processor configurations, enabling complex control algorithms and high-speed arithmetic processing in demanding industrial environments. By offloading specific bit and word execution tasks, the CPU 928A ensures deterministic cycle times and maintains system stability in critical applications such as power generation, chemical processing, and heavy manufacturing.

Features

  • Dual-processor architecture for independent handling of binary and word-based mathematical operations.
  • Optimized for multi-processor backplane communication, allowing up to four CPUs to operate in parallel without memory contention.
  • Integrated slot for interchangeable EPROM or RAM memory submodules.
  • Front-panel status LED array for real-time diagnostics, including battery health, synchronization status, and operational mode.
  • Standardized programming interface for rapid configuration and troubleshooting.

Applications

The CPU 928A is primarily utilized in large-scale automation systems requiring high availability and complex logic processing. It is a standard component for S5-135U and S5-155U racks where multiple processors are required to manage dense I/O counts and high-speed control loops.
