CJ1W-CORT21 | Omron | Contrôleur programmable

Description

Designed to integrate CANopen fieldbus communication into Omron control architectures, the CJ1W-CORT21 operates as a high-performance CPU Bus Unit within the CJ Series PLC platform. This module enables seamless data exchange between CJ-series programmable controllers and standard CANopen network devices, including drives, sensors, and remote I/O systems.

The unit installs directly onto either a CPU Rack or an Expansion Rack, with support for up to 16 master/configurator units per PLC system depending on rack power constraints. Hardware-based configuration features, such as integrated front-panel rotary and DIP switches, allow for direct troubleshooting and commissioning without complex software intervention during basic setup.

Features

• Direct integration into Omron CJ-series CPU and Expansion Racks.
• Supports up to 16 units connected to a single PLC system.
• Rotary switch for simple, hardware-based hexadecimal unit number configuration (0 to F).
• Front-panel DIP switches for direct baud rate selection.
• Requires 11 to 25 VDC network power supply via the communications connector.

Applications

• Industrial factory automation networks
• Multi-axis motion control and drive integration
• Distributed packaging and material handling systems
• Assembly lines utilizing CANopen-compliant field devices

Installation Guidelines

• Power Isolation: Always isolate the PLC system power supply before mounting, wiring, or removing the CPU Bus Unit.
• Address Configuration: Set the unique unit number (0 to F) using the hexadecimal rotary switch prior to installation to prevent addressing conflicts on the backplane bus.
• Network Termination: Ensure proper termination resistors (typically 120 ohms) are installed at both physical ends of the CANopen network trunk line.
• Shielding and Grounding: Connect the CAN network cable shield to ground at a single point to mitigate electromagnetic interference in high-noise environments.
