Siemens 6ES7 288-1ST20-0AA0 | SIMATIC S7-200 SMART CPU ST20
Product Overview
The Siemens 6ES7 288-1ST20-0AA0 is a DC/DC/DC configuration standard CPU module belonging to the SIMATIC S7-200 SMART series, designed for compact automation control scenarios. It integrates rich I/O interfaces, high-speed processing capabilities, and reliable communication functions, making it suitable for small and medium-sized automated control systems in industrial fields such as intelligent manufacturing, equipment automation, and process control. The module supports programming via STEP 7 Micro/WIN SMART software and enables flexible expansion to meet diverse control needs[14].
Key Functions
- Integrated High-Density I/O: Equips 12-channel 24V DC digital inputs (DI) and 8-channel 24V DC digital outputs (DO), reducing external expansion needs and simplifying system wiring[14].
- Efficient Processing Performance: Provides fast instruction execution speed, supporting bit operations, word operations, and floating-point operations to ensure real-time response of control tasks[17].
- Diverse Communication Interfaces: Integrates Ethernet interface (PROFINET) and RS-485 interface (PPI/MPI/Free Port), enabling seamless connection with HMI, SCADA, and other controllers, and supporting multi-protocol communication[14].
- Reliable Data Storage: Equips program memory, data memory, and hold memory to ensure non-volatile storage of key programs and data during power failure[19].
- Built-in Real-Time Clock (RTC): Supports time synchronization and timed task execution without additional battery configuration[14].
