Siemens 6ES7 288-1ST20-0AA0 | SIMATIC S7-200 SMART CPU ST20
Product Overview
The 6ES7 288-1ST20-0AA0 (also identified as 6ES72881ST200AA0) is a core CPU module from the SIMATIC S7-200 SMART 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.
Key Functions
- High-Density Integrated I/O: Equips 12 × 24V DC digital inputs (DI) and 8 × 24V DC digital outputs (DO) with transistor logic, enabling direct connection of field devices and reducing overall system complexity.
- Rapid Processing Performance: Delivers fast instruction execution to ensure real-time responsiveness for time-critical control tasks, supporting complex logic operations and arithmetic processing.
- Comprehensive Communication Interfaces: 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.
- Reliable Data Retention: Incorporates non-volatile program and data memory to safeguard user programs and critical process data during power outages or system restarts.
- Built-in Real-Time Clock (RTC): Supports time-stamping of events and execution of timed tasks without the need for an external battery.
