  • 1.Overview

    The GCAN-205 is a CAN-Bus and ethernet converter. GCAN-205 can convert the data between CAN-Bus and Modbus TCP. With this converter, equipment that used Modbus TCP protocol can connect to CAN-Bus without changing the hardware structure, this makes multi-Bus interconnection very flexible, and extends the application scope of CAN-Bus.

    2.Properties at a glance

    2.1Hardware

     High-speed 32-bit processor;
     Embedded hardware watchdog timer;
     Power supply voltage: DC 24V, maximum current: 40mA;
     Electrostatic discharge immunity level: contact discharge ± 2KV, air discharge ±15KV;
     Electrical fast transient burst immunity level: ± 1KV;
     Surge immunity level: ± 1KV;
     Operating temperature range: -40℃ ~ +85℃;
     Operating humidity range: 5% to 95% RH no condensation;
     Dimensions:113mm * 100mm * 21mm;
     Standard DIN rail mounting, designed for industrial design.

    2.2CAN

     Integrated 1 CAN-Bus interface with terminal;
     CAN-Bus signals include: CAN_H, CAN_L, CAN_GND;
     CAN-Bus supports CAN2.0A and CAN2.0B frame format, conform to ISO/DIS  11898 standards;
     CAN-Bus baud rates range from 5Kbps to 1Mbps;
     CAN-Bus isolation converter insulation voltage: DC 1500V.

    2.3Ethernet

     RJ45, support 10 / 100M adaptive;
     Modbus slave support function code: 03H, 04H, 06H, 16H;
     Support static or dynamic IP access;
     Support heartbeat and timeout interrupt function;
     The working port is fixed, the target IP and the target port can be set;
     After the network is disconnected, the connection resource is automatically restored and the CP connection is established reliably;
     Support protocols include EtherNET, ARP, IP, ICMP, UDP, DHCP, DNS, TCP;
     Compatible with SOCKET work (TCP Server, TCP Client, UDP, etc.), the host computer communication software follows the standard SOCKET rules.


    3.Examples

    Users can send the Modbus instruction through the network debugging software in the CD. Please choose the TCP Client mode and the remote host address is 192.168.1.10:502 (IP address for the factory settings, can be modified; port number can not be modified).
    Please note: check the "十六进制显示" and "十六进制发送" when using the software Network Debugging Assistant.


    3.1Read the received CAN frame

    For example:
    Modbus slave address: 1
    Modbus register first address: 0x01 (factory setting)
    Function code: 03
    Frame format: standard frame
    Frame ID: 0x181
    CAN frame data: 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08
     
    Modbus master sends request frame:
    00 00 00 00 00 06 01 03 00 01 00 04


    Response frame of GCAN-205:
    00 00 00 00 00 0B 01 03 08 02 01 04 03 06 05 08 07

     

    At this point, the GCAN-205 converter receives a data frame with CAN ID of 0x181.
     

    3.2 Write the CAN frame to be sent

    For example:
    Modbus slave address: 1
    Modbus register first address: 0x101(decimal value is 257, factory setting)
    Function code: 16(10H)
    Frame format: standard frame
    Frame ID: 0x201
    CAN frame data: 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08
     
    Modbus master sends request frame:
    00 00 00 00 00 0F 01 10 01 01 00 04 08 02 01 04 03 06 05 08 07

    Response frame of GCAN-205:
    00 00 00 00 00 06 01 10 01 01 00 04

    At this point, the CAN terminal of other converters receive a data frame with a CAN ID of 0x201 from the Modbus side.
