The 3NC154.60-2 is a professional CAN bus communication controller developed by B&R Industrial Automation, belonging to the company’s mature modular automation product line. Designed for industrial field bus communication, this module serves as a core gateway and data exchange unit between controllers, I/O modules, servo drives, sensors and other field devices. It adopts industrial-grade communication circuits and complete electrical isolation design, delivering strong anti-interference ability and stable data transmission performance in complex electromagnetic environments. Featuring a compact modular structure and standard DIN rail mounting, it can be flexibly installed inside industrial control cabinets to save space and simplify system wiring. The module supports CAN bus standard protocols and can work independently or collaborate with other B&R controllers and functional modules to build distributed industrial control systems, which is widely used in scenarios requiring reliable multi-device networking and real-time data interaction.

The official model of the product is 3NC154.60-2, an original B&R product manufactured in strict accordance with the group’s global quality management system and international electrical safety standards. It has obtained CE certification and complies with relevant EU directives on safety and electromagnetic compatibility. The module has an IP20 protection rating and is intended for indoor installation in standard industrial control cabinets. It is powered by 24 VDC industrial power supply with low overall power consumption, and the power supply circuit is equipped with over-voltage and reverse-connection protection to ensure power supply safety. All configuration, protocol setting, parameter debugging and network diagnosis operations are completed through the unified B&R Automation Studio software platform. As a standard communication module, it is fully compatible with B&R’s complete series of PLCs, motion control modules and peripheral equipment, and is supplied as a new original part for new project deployment and old equipment replacement and maintenance worldwide.

As a dedicated CAN bus controller, the 3NC154.60-2 undertakes the core functions of CAN bus signal transceiver, data parsing, protocol conversion and network management in industrial automation systems. It complies with standard CAN 2.0A and CAN 2.0B protocols, and supports standard and extended data frames, enabling seamless connection and data interaction with all CAN-bus compatible third-party devices. The module supports flexible node address configuration, with an address range covering 0 to 255, which can meet the networking requirements of large-scale multi-node systems. It provides adjustable communication baud rate, adapting to different transmission distance and real-time performance requirements on site.

The built-in high-performance communication processor can realize high-speed and stable data sending and receiving, and supports multi-point communication, broadcast communication and point-to-point communication modes. It integrates complete bus fault diagnosis functions, which can automatically detect bus short circuit, signal interruption, communication conflict and other abnormal conditions, and feed back fault information to the upper controller in a timely manner to facilitate rapid troubleshooting. The module also has data filtering and error correction mechanisms, which can effectively filter interference signals on industrial sites and ensure the accuracy and integrity of transmission data. It can be used as a main station to manage the entire CAN bus network, or as a slave station to respond to commands from the main station. It can expand the communication capacity of the main controller, break through the limitation of traditional point-to-point wiring, and build a concise and efficient distributed control network. It is an essential core component for realizing interconnection and intercommunication of equipment in intelligent factories and automated production lines.

The 3NC154.60-2 adopts a dedicated industrial communication chip as the core, with a maximum CAN bus transmission rate up to 10 Mbps, which can meet the high real-time data transmission requirements of most industrial motion control and signal acquisition scenarios. The communication interface uses standard terminal blocks or dedicated bus connectors, supporting hot plugging under non-fault conditions to facilitate on-site module replacement and maintenance. The working power supply is 24 VDC, with stable and low power consumption, and the power circuit has built-in over-current, over-voltage and reverse polarity protection.

In terms of environmental adaptability, the rated operating temperature ranges from -20°C to +60°C, and the storage temperature ranges from -40°C to +85°C. It can operate normally under a relative humidity of 5% to 95% non-condensing, and has good resistance to industrial dust, moisture and electromagnetic interference. Multiple LED status indicators are arranged on the panel to display real-time status such as power-on, bus communication, data transceiving and fault alarm, helping on-site personnel to observe the operating status and locate faults quickly. The whole module adopts isolation design between the bus circuit and the internal logic circuit, which effectively isolates electrical interference between different devices and improves the overall stability and safety of the system. The communication distance can be adjusted according to the baud rate, supporting long-distance stable transmission in large workshops and complex production lines.

For on-site installation and networking, dedicated CAN bus cables, 24 VDC power cables and matching terminal accessories need to be equipped separately. The module is compatible with standard DIN rails and installation brackets used in B&R automation systems, which can realize fast and firm installation. According to the on-site networking mode, matching bus terminators are required to optimize signal transmission quality. B&R Automation Studio is the exclusive supporting software for this module, which is used for protocol configuration, baud rate setting, node address allocation, communication monitoring and fault diagnosis. It can be matched with all B&R PLCs, servo drives, counter modules, human-machine interfaces and CAN-bus compatible third-party sensors and actuators, forming a complete CAN bus distributed control system.

The 3NC154.60-2 CAN bus controller is widely applied in various industrial automation scenarios that require multi-device networking and real-time bus communication. It is commonly used in automated assembly lines, packaging machinery, textile equipment, printing machinery, material handling systems and general mechanical manufacturing equipment. It also performs excellently in intelligent logistics equipment, light industrial robots, gantry motion systems and auxiliary control units of machine tools. Whether it is small-scale single-unit equipment networking or large-scale multi-axis and multi-equipment linkage control, this module can provide stable and reliable bus communication support. Its highly integrated design reduces the use of traditional wiring, lowers the complexity of system construction and subsequent maintenance, and effectively saves the overall operation cost. It is suitable for both new automation projects and network transformation and upgrading of old production lines.
