Schneider TWDNCO1M CANopen Bus Master Module for Twido PLC

Why Choose the Schneider TWDNCO1M for Your CANopen Network?

When your automation system demands reliable, high-speed communication between controllers and field devices, the Schneider TWDNCO1M CANopen bus master module delivers seamless integration. This module acts as the central coordinator for up to 16 slave devices, ensuring data flows efficiently across your Twido PLC network. Whether you are upgrading an existing line or building a new system, the TWDNCO1M provides the performance and compatibility you need.

Product Overview

The Schneider TWDNCO1M is a CANopen bus master module designed for the Twido programmable logic controller series. It connects via a male SUB-D 9-pin connector using two twisted shielded pairs, supporting the CANopen M10 DR 303-2 and DS 301 V4.02 protocols. This module enables your Twido controller to communicate with a wide range of CANopen-compatible drives, sensors, and actuators, simplifying system architecture and reducing wiring.

Industry Applications

Manufacturing facilities use the TWDNCO1M to coordinate motor drives and sensors on assembly lines. For example, a packaging line can employ this module to synchronize conveyors and labeling machines via CANopen, reducing downtime and improving throughput. In material handling systems, the module manages up to 16 slave nodes, enabling precise control of sorters and lifts. Its compact size and IP20 rating make it suitable for control cabinets in factories and warehouses.

Installation & Setup Guidance

Mount the TWDNCO1M on a DIN rail inside your control panel. Connect the 24 V DC power supply to the module terminals, observing polarity. Use a shielded twisted-pair cable with a male SUB-D 9 connector for the CANopen bus. Set the transmission rate via your Twido programming software to match your network length—125 kbit/s for longer distances or 500 kbit/s for shorter runs. Configure the module as the bus master and assign node IDs to each slave device. Verify communication using the PWR LED; a steady green light indicates normal operation.

Maintenance & Reliability

Regularly inspect the SUB-D connector for secure mating and check the power supply voltage to ensure it stays within 24 V DC ± tolerance. Keep the module free of dust and moisture, as IP20 does not protect against liquid ingress. The TWDNCO1M dissipates only 1.2 W, so it generates minimal heat, but ensure adequate airflow in the cabinet. Following these simple steps maximizes uptime and extends service life, delivering strong ROI for your automation investment.

Compatibility & Integration

The TWDNCO1M is compatible with the following Twido base controllers: TWDLMDA20DRT, TWDLCAE40DRF, TWDLMDA20DTK, TWDLCDA40DRF, TWDLCAA40DRF, TWDLMDA40DUK, TWDLCAA24DRF, TWDLMDA40DTK, TWDLCDE40DRF, TWDLCDA24DRF, and TWDLMDA20DUK. It supports CANopen M10 DR 303-2 and DS 301 V4.02 standards, ensuring interoperability with standard CANopen devices. You can integrate up to one module per base controller, making it a straightforward addition to your existing Twido system.

Selection Guide & Purchasing Advice

Before ordering, confirm that your Twido controller model appears in the compatibility list above. Verify that your CANopen slave devices support the same transmission rates and protocol version. The TWDNCO1M requires an external 24 V DC supply; ensure your power source can deliver at least 50.5 mA at 24 V.
