<\/div>\n

Product Overview<\/h2>\n
<\/div>\n
The 6ES7 288-1ST20-0AA0<\/strong> (also identified as 6ES72881ST200AA0<\/strong>) is a core CPU module<\/strong> from the SIMATIC S7-200 SMART<\/strong> series, engineered for compact and efficient industrial automation control. It combines a powerful processor, integrated I\/O interfaces, and versatile communication capabilities in a space-saving design, making it the ideal solution for small-to-medium-sized automation systems across manufacturing, process control, and building automation. As a stand-alone controller, it eliminates the need for external expansion modules for basic tasks, while supporting flexible scaling to meet evolving project requirements.<\/div>\n
<\/div>\n

Key Functions<\/h2>\n
<\/div>\n
    \n
  • High-Density Integrated I\/O<\/strong>: Equips 12 \u00d7 24V DC digital inputs (DI) and 8 \u00d7 24V DC digital outputs (DO) with transistor logic, enabling direct connection of field devices and reducing overall system complexity.<\/li>\n
  • Rapid Processing Performance<\/strong>: Delivers fast instruction execution to ensure real-time responsiveness for time-critical control tasks, supporting complex logic operations and arithmetic processing.<\/li>\n
  • Comprehensive Communication Interfaces<\/strong>: Features an integrated Ethernet (PROFINET) interface for high-speed data transfer and an RS-485 interface for multi-drop networking, supporting protocols such as PPI, MPI, and Freeport for seamless integration with HMIs, SCADA systems, and third-party devices.<\/li>\n
  • Reliable Data Retention<\/strong>: Incorporates non-volatile program and data memory to safeguard user programs and critical process data during power outages or system restarts.<\/li>\n
  • Built-in Real-Time Clock (RTC)<\/strong>: Supports time-stamping of events and execution of timed tasks without the need for an external battery.<\/li>\n<\/ul>\n
