HD67001 – CANopen to Modbus RTU Master converter RS232/RS485 with DIN rail mounting

Industrial CANopen to Modbus RTU master (RS232 or RS485) converter, housing type A (slim), DIN rail mount.

The HD67001 converter allows you to connect several Modbus RTU slaves with an existing CANopen network, ensuring transparent and reliable data exchange between the two widely used protocols. This makes it a key solution for industrial automation environments where legacy Modbus devices must be integrated into more advanced CANopen infrastructures.

Converter is easy to configure thanks to the free SW67001 software, which provides an intuitive PC-based environment for parameter setting. Within the tool, users can map Modbus registers to CANopen PDO and SDO objects, define node guarding rules, and adjust communication parameters to match both new and existing systems. This streamlined configuration process reduces commissioning time and minimizes integration errors, making the device particularly suitable for system integrators.

Thanks to its dual Modbus connectivity (RS232 and RS485) and the CAN 2.0 compliant interface, the HD67001 provides flexibility in deployment. It supports CANopen data rates from 10 kbps to 1 Mbps and Modbus speeds up to 115 kbps. This ensures compatibility with a wide variety of devices, from low-speed sensor networks to high-performance controllers. The galvanic isolation between buses improves signal integrity, eliminates ground loops and protects against electrical disturbances.

The compact housing type A design makes it ideal for DIN rail cabinets where space is limited. Despite its slim form factor, the device is designed for industrial reliability, with an operating temperature range from -40°C to +85°C. This robustness allows installation in harsh environments, including outdoor control boxes and high-temperature industrial facilities.

Typical applications of the HD67001 include:

• Integration of PLC systems with CANopen-based machine networks
• Connection of HVAC and BMS Modbus devices to CANopen controllers
• Bridging robotics controllers or field sensors into supervisory systems
• Upgrading older Modbus-based installations with CANopen-compatible infrastructure
• Use in transportation, energy management, and industrial machinery where mixed communication standards coexist

By supporting both PDO and SDO management, the converter allows detailed customization of data mapping, while node guarding ensures system stability and prevents network conflicts. Combined with Modbus master capabilities, it guarantees bi-directional and synchronous data transfer between field devices and supervisory networks.
