  • 1 Overview

    GCAN-204 converter has one CAN-Bus interface, one serial interface. The GCAN-204 integrates the Modbus RTU protocol. With the GCAN-204 , user can use the serial bus connect to other equipment (with Modbus RTU protocol)  access the CAN-Bus communication interface.GCAN-204 has integrated isolation protection module. Using DIN railway fixed, it can be easier to integrate into the control cabinet.

    3. Examples

    The user can use the included serial debugging assistant to send Modbus instruction debugging.
    Please note: choose "hexadecimal display" and "hexadecimal send" when using the serial debugging assistant.

    3.1 Receive CAN data

    For example, configure the Modbus slave address: 1, Modbus register first address: 0x01, CAN: standard frame, frame ID: 0x181, CAN frame data: 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08.
    User Modbus master sends request frame:
    01 03 00 01 00 04 15 C9
    GCAN-204 response frame:
    01 03 08 02 01 04 03 06 05 08 07 17 C1
    Please note that the CRC is calculated by the CRC16 checksum calculator. (With disk)
    At this point, the GCAN-204 module has received a data frame with a frame ID of 0x181 from the CAN terminal of other equipment.

    3.2 Transmit CAN data

    For example, Modbus slave address: 1, Modbus register first address: 0x101 (decimal: 257), function code: 16 (10H), CAN: standard frame, frame ID: 0x201, CAN frame data: 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08.
    User Modbus master sends request frame:
    01 10 01 01 00 04 08 02 01 04 03 06 05 08 07 CB 2E
    GCAN-204 response frame:
    01 10 01 01 00 04 91 F6
    Please note that the CRC is calculated by the CRC16 checksum calculator.
    At this point, the CAN terminal of other equipment has received a data frame with a frame ID of 0x201 from the Modbus side of the GCAN-204 module.
