Product Description
Siemens SIMATIC S7 1200 CB 1241 RS 485 Communication Board
6ES7241-1CH30-1XB0
The Siemens 6ES7241-1CH30-1XB0 is a communication board (CB 1241) designed specifically for the SIMATIC S7-1200 PLC series. This compact and efficient module provides an RS-485 interface, enabling seamless serial communication for a wide range of industrial automation tasks. It is ideal for point-to-point (PtP) connections, supporting common protocols like Modbus RTU and USS (Universal Serial Drive Interface), making it a versatile solution for connecting to third-party devices, sensors, drives, and other automation components. The module features a convenient terminal box (junction box) for simplified and rapid wiring.
Key Features
  • RS-485 Interface: Equipped with a robust RS-485 port that supports differential signal transmission, providing excellent noise immunity and enabling reliable long-distance communication up to 1000 meters (at lower baud rates).
  • Protocol Support: Natively supports point-to-point protocols, including Modbus RTU (as both master and slave) and the USS protocol for direct control of Siemens drives.
  • Free Port Mode: Allows for flexible, user-defined communication protocols, enabling custom data exchange with non-Siemens devices like barcode readers or custom instrumentation.
  • Convenient Wiring: The integrated terminal box provides a clear and accessible wiring interface, significantly reducing installation time and effort.
  • Multi-Drop Capability: Supports connecting up to 32 nodes on a single bus, making it cost-effective for networking multiple devices.
  • Simple Commissioning: Can be easily configured within the TIA Portal or STEP 7 Basic engineering software, with user-friendly parameter assignment tools.
  • Compact Design: The small form factor allows for direct mounting onto the S7-1200 CPU without increasing the overall footprint of the controller.
Applications
  • Drive Control: Connecting and controlling Siemens MICROMASTER and SINAMICS drives using the USS protocol for speed and parameter management.
  • Sensor Integration: Networking multiple smart sensors and instruments (e.g., temperature, pressure, flow meters) that use the Modbus RTU protocol.
  • Third-Party Device Communication: Interfacing with equipment from other manufacturers, such as barcode scanners, weigh scales, or robot controllers, via free port or Modbus.
  • Remote I/O Networking: Connecting remote I/O blocks or other controllers in a master-slave configuration.
  • SCADA Integration: Serving as a communication gateway to send data from the S7-1200 to a Supervisory Control and Data Acquisition (SCADA) system.
