Siemens 6ES7241-1CH30-1XB0

A compact communication board for SIMATIC S7-1200 systems, providing an RS485 interface with terminal connection and support for Freeport communication.

Communication at a Glance

Flexible Serial Communication

The CB 1241 RS485 board is designed for serial communication within SIMATIC S7-1200 systems. Its protocol support makes it suitable for connecting controllers with devices that communicate through RS485-based serial networks.

Communication Loss

A missing or unstable RS485 communication path can interrupt data exchange between the S7-1200 controller and connected serial devices.

Modbus RTU Replacement

When an RS485 communication board becomes defective, the CB 1241 is relevant when the system requires Modbus RTU master or device communication.

Production Downtime

Loss of serial communication may prevent field data from reaching the controller, potentially affecting automated sequences and machine operation.
