Description

The Siemens 6ES5928-3UA11, also known as the CPU 928A, is a high-performance processor module designed for the SIMATIC S5 automation system. Specifically engineered for use within the S5-135U and S5-155U programmable logic controller (PLC) families, this module serves as the central processing unit responsible for executing user programs, managing I/O data, and coordinating communication across the backplane bus. As a legacy component, this unit is essential for maintaining and extending the operational life of existing S5-based industrial control systems.

Features

  • Central processing unit for SIMATIC S5-135U and S5-155U systems.
  • High-speed instruction processing for complex automation tasks.
  • Integrated interface for system-wide data exchange and peripheral management.
  • Robust design suitable for demanding industrial environments.
  • Direct replacement or spare for legacy S5-155U/135U rack configurations.

Applications

The CPU 928A is primarily utilized in large-scale industrial automation applications where the SIMATIC S5-135U or 155U platforms are deployed. Typical environments include heavy manufacturing, power generation facilities, chemical processing plants, and legacy material handling systems that require high-reliability control logic.
