Our 2-Serial Ports EtherNet/IP gateway, the GT200-EI-2RS485 provides a seamless connection between multiple Modbus devices with RS-485 interface and EtherNet/IP network.

 Technical Specification:

  • EtherNet/IP network is independent with two Modbus networks.
  • Ethernet 10/100M adaptive.
  • Supports IP addresses conflict detection function.
  • Supports the ODVA Standard EtherNet/IP communication protocol.
  • Two serial RS-485 interfaces, half-duplex, and baud rate support: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200; parity support: none, odd, even, mark, space; 1 or 2 stop bits.
  • GT200-EI-2RS485 acts as master at the side of Modbus network:
    • Supports 01H, 02H, 03H, 04H, 05H, 06H, 0FH, 10H function codes, can be configured up to 48 Modbus commands for each RS-485 interface;
    • Modbus function codes 03H, 04H, 06H and 10H support the "Byte Swap" function, and it can help users solve the problem of data format between two different networks.
