BECKHOFF CX2020-N031-0001 Module CPU de base

The CX2020-N031-0001 is a specialized Basic CPU module for the BECKHOFF CX2020 series of embedded controllers. This module is designed to provide serial communication capabilities via an integrated RS485 interface (9-pin D-sub socket). It is factory-configured for use as an end point in an RS485 network topology, featuring enabled echo and active termination, which ensures signal integrity at the end of the bus segment.

Note: This module is categorized under the "service phase," indicating it is intended for maintenance, replacement, or legacy support within existing automation systems.

Features

• Device Type: Basic CPU module (Service Phase)
• Interface: RS485 (9-pin D-sub socket)
• Configuration: End point, with echo, termination on
• Compatible with CX2020 embedded controller systems

Applications

• Industrial serial communication in automation networks
• Terminal node connectivity for RS485 serial bus segments
• Integration of serial field devices into existing CX2020-based control architectures

Technical Specifications

Installation Guidelines

• Ensure the CPU module is firmly seated within the CX2020 system to maintain reliable power and bus communication.
• Since this module is configured as an end point (termination on), it should be placed at the physical extremity of your RS485 network to prevent signal reflections.
• Use a high-quality shielded 9-pin D-sub cable for serial connections.
• Verify your serial communication settings (e.g., baud rate, parity) within the TwinCAT environment to ensure compatibility with your network devices.
• Given its service phase status, ensure that this module matches the exact requirements of your existing infrastructure during replacement or maintenance.
