Description
ModbusRTU-CAN is an industrial grade Modbus RTU to CAN module that integrates 1 standard serial port and 1 standard CAN bus interface. The ModbusRTU-CAN serial bus terminal has integrated the Modbus RTU protocol. Using ModbusRTU-CAN, users can connect devices that originally used the serial bus for communication (Modbus RTU protocol) to the CAN bus communication interface without changing the original hardware structure. This enables devices that use the Modbus RTU protocol for communication to quickly connect to the CAN bus and form nodes in the CAN bus network.
When ModbusRTU-CAN reads data from Modbus, it will load the data received on the CAN bus into the cache in real time and wait for Modbus commands to read. After receiving the Modbus read command, the module will convert the specified CAN data and send it to the Modbus bus; When the module receives a Modbus data transmission command, it will directly process the Modbus data and send it to the CAN bus.
ModbusRTU-CAN is a key tool for industrial bus transformation and interconnection of multiple bus devices. At the same time, this module has the characteristics of small size, plug and play, and is also the best choice for existing system integration. The various bus interfaces of ModbusRTU-CAN are integrated with isolation protection modules to prevent damage to the module caused by instantaneous overvoltage and overcurrent. The standard 35mm DIN rail fixing method makes it easier to integrate into various control cabinets.
Features:
1. Modbus slave support function codes: 03H, 04H, 06H, 16H;
2. The standard serial port adopts a 2-wire RS485 interface;
3. The serial port baud rate supports a range of 9600bps~115200bps and can be configured through software;
4. CAN bus supports CAN2.0A and CAN2.0B frame formats and complies with the ISO/DIS 11898 specification;
5. The CAN bus communication baud rate ranges from 20Kbps to 1Mbps and can be configured through software;
6. The CAN bus interface adopts electrical isolation, and the insulation voltage of the isolation module is DC 1500V;
7. Maximum conversion data flow: 400 frames per second (measured at a serial port baud rate of 115200);
8. Use 9~28V DC power supply (recommended 12V 1A);
