Information About 6ES7241-1CH32-0XB0
The 6ES7241-1CH32-0XB0 is part of the SIMATIC S7-1200 CM 1241 communication module family, engineered to extend the serial connectivity of Siemens’ compact S7-1200 controllers. Built with a rugged design, it provides a single RS422/485 interface capable of cable lengths up to 1,000 meters, making it suitable for distributed serial device networking. The module integrates tightly with the S7-1200 platform and TIA Portal, supporting a wide range of serial protocols including Modbus RTU master/slave, USS, ASCII, Freeport, and 3964(R), all configurable through libraries or native functions. Common applications include serial device interfacing, legacy equipment integration, and field communication with drives, sensors, and third-party controllers. Its robust electrical characteristics, protocol flexibility, and diagnostics make it a dependable choice for serial communication expansion in small to medium automation systems.
Key Features:
- RS422/485 communication port: Supports long-distance serial communication up to 1,000 meters.
- Wide protocol support: Modbus RTU master/slave, USS, ASCII, Freeport, and 3964(R).
- S7-1200 system integration: Fully compatible with SIMATIC S7-1200 controllers and TIA Portal.
- Flexible configuration: Programmable telegram length up to 1 kB with multiple parity and stop-bit formats.
- Compact module design: Low power consumption and efficient backplane operation.
- 9-pin SUB-D connector: Standardized and robust interface for industrial serial devices.
- Diagnostics support: Enables monitoring and troubleshooting of communication status.
- High compatibility range: Supports up to 247 Modbus slaves per network segment (with repeaters).
The 6ES7241-1CH32-0XB0 delivers the reliability and precision required for stable serial communication in distributed industrial automation.
