III. Core CAN Bus Specifications

1. Bus Interface and Protocol

Channel Configuration: 1 independent CAN 2.0A/B interface, supports CANopen standard protocol (CiA 301/401/402).

Operating Mode: Software-configurable CANopen master or slave, master supports up to 127 slave nodes, slave address range 1～127.

Transmission Rate: Programmable from 10k to 1Mbps, common rates 125kbps, 250kbps, 500kbps, 1Mbps, suitable for different distances and node scales.

Bus Topology: Supports linear and star topologies, terminal resistor built-in selectable (120Ω), simplifies wiring.

2. Data Interaction Capability

PDO Communication: Supports real-time transmission of process data objects (PDO), master can configure up to 32 sending/receiving PDOs, each PDO up to 8 bytes of data, suitable for high-speed I/O and motion data interaction.

SDO Communication: Supports point-to-point communication of service data objects (SDO), used for parameter configuration, program download, and fault diagnosis, data transmission length up to 256 bytes.

NMT Management: Supports network management (NMT) service, realizes node startup, stop, reset, and status monitoring, ensures stable operation of the bus network.

Synchronization Function: Supports CANopen synchronization objects (SYNC), period configurable from 1 to 100ms, suitable for multi-axis synchronous motion control.

IV. Electrical Characteristics and Isolation Protection

Power Supply: 24VDC (±10%), powered by the system bus, no additional power supply required, equipped with reverse polarity, overvoltage, and overcurrent protection. Power Consumption: Normal operation is approximately 3.8W, standby is about 1.2W. The design is low-power, reducing the system's heat dissipation pressure.

Electrical Isolation: The CAN bus interface is electrically isolated from the PLC system, with an isolation voltage of 2500VAC. This effectively suppresses ground potential interference and electromagnetic noise.

Bus Protection: Built-in CAN bus overvoltage, overcurrent, and static protection, capable of withstanding harsh electrical conditions in industrial sites.

V. Functional Features

1. Master Station Function

Network Management: Automatically scans slave station nodes, configures node parameters, monitors node status, supports automatic isolation and recovery of faulty nodes.

Motion Control Integration: Compatible with CiA 402 motion protocol, can directly control CANopen servo drives and frequency converters, achieving position, speed, and torque closed-loop control.

Data Mapping: Supports automatic mapping of PDO data to the PLC's process data area, simplifying programming and improving data interaction efficiency.

2. Slave Station Function

Flexible Configuration: Can be used as a CANopen slave station to connect to third-party master station systems, supporting custom PDO mapping and parameter configuration.

Data Interaction: Responds to master station PDO/SDO instructions in real time, uploads PLC I/O status and process data, and receives master station control instructions.

3. Diagnosis and Maintenance

LED Status Indicators: The module's front panel is equipped with power, bus activity, and fault LEDs, displaying real-time module operation, bus communication, and fault status.

Software Diagnosis: Through Automation Studio, the total bus load, node status, and fault codes (such as bus breakage, node loss, communication errors) can be read. Supports remote diagnosis and maintenance.

Bus Monitoring: Built-in bus load rate statistics function, real-time monitoring of bus data traffic, predicting bus congestion risks.

VI. Typical Application Scenarios

Distributed I/O System: Connects CANopen remote I/O modules to expand PLC control points, suitable for large production lines and distributed control of assembly lines.

Multi-axis Motion Control: Acts as the master station to control multiple CANopen servo drives, achieving multi-axis synchronization, electronic gearing, and cam following, suitable for machine tools, textile, and printing equipment.

Device Networking Communication: Connects third-party CANopen devices (frequency converters, sensors, instruments) to achieve data interaction between PLC and third-party devices, suitable for renovation scenarios of new and old equipment.

Fieldbus Network Construction: Builds a CANopen bus network in System 2005, replacing traditional hard wiring, simplifying wiring, reducing costs, and enhancing system reliability.

Industrial Internet of Things Data Collection: Acts as a CANopen network gateway, collects on-site equipment data and uploads it to the upper computer or cloud platform, suitable for industrial 4.0 data collection and monitoring scenarios.
