CANbus to Modbus RTU and TCP converters – Efficient protocol integration

CANbus to Modbus RTU and TCP converters – Ideal solutions for industrial system integration

In this category, you will find CANbus to Modbus RTU and TCP converters designed to enable smooth communication between devices operating on different protocols. These converters bridge the gap between CANbus networks (including CAN 2.0A, CAN 2.0B, and CANopen) and Modbus RTU or Modbus TCP infrastructures. This is particularly useful for industrial environments where a wide variety of devices, controllers and monitoring systems need to work in a synchronised, centralised way. Applications range from building automation and SCADA systems to PLCs, HMIs, and more.

The converters in this category allow for the integration of sensors, actuators, controllers and embedded systems based on CANbus with Modbus-compatible supervisory or control units. This opens the possibility for efficient, bi-directional communication and improved monitoring, data logging and system control – whether in industrial production lines or automotive systems.

Why choose our CAN to Modbus converters?

The converters we offer are designed for demanding applications in both industrial and automotive environments. With support for both Modbus RTU over RS-485 and Modbus TCP over Ethernet, they provide maximum flexibility for integrating legacy and modern equipment. CANbus is a highly reliable and deterministic protocol commonly used in:

• Automotive systems – such as engine control units, diagnostics, sensor data logging.
• Industrial automation – including temperature and pressure sensors, actuators, and distributed control units integrated into Modbus-based control systems.

Our converters stand out for their durability and technical performance:

• EMC protection – ensures stable communication in environments with electromagnetic interference.
• Wide operating temperature range – from -40°C to 85°C in standard models; up to 105°C in automotive-grade units.
• DIN rail or panel mounting – for flexible installation in control cabinets or enclosures.
• Automotive-grade isolation – 4kV isolation between CAN, RS-485 and Ethernet ports for maximum safety and noise immunity.

Model variety and advanced functionality

Depending on your specific project needs, you can choose from a range of converter models with various interfaces and features:

• CAN 2.0 and CANopen support – for easy integration with modern and legacy CAN systems.
• RS-485 interface – for direct connection to Modbus RTU master/slave devices such as PLCs and HMIs.
• Ethernet port (RJ45) – for integration with Modbus TCP/IP networks and remote access applications.
• IP67 enclosures – designed for harsh outdoor use, including mobile systems and field installations.

Every converter comes with free, user-friendly configuration software that allows the quick setup of protocol parameters, data mapping, diagnostics, and firmware updates.

Application examples for CAN to Modbus converters

• Heating control systems – transferring sensor data from CAN-based modules into Modbus RTU networks.
• SCADA systems – accessing distributed CAN devices through Modbus TCP for remote monitoring and control.
• Industrial machinery – allowing legacy Modbus PLCs to read/write data from new CAN sensors or controllers.
• Mobile platforms and robotics – synchronising embedded CAN systems with Modbus-based master controllers.
