Modbus / EtherNet/IP Adapter




The GT100-EI-RS can connect multiple Modbus devices to the EtherNet/IP network.

 Technical Specification:

  • Independent between EtherNet/IP network and Modbus network.
  • Ethernet 10/100M self-adaptive.
  • IP address conflict detection.
  • Supports ODVA standard EtherNet/IP communication protocol.
  • Supports RS485 or RS232 on serial interface, half duplex, baud rate: 1200,2400, 4800, 9600, 19200,38400, 57600, 115200 bps optional, check bit: None, odd, even, mark and space optional; 1 or 2 bit stop bit optional.
  • Act as Modbus Master at Modbus side:
    • Supports function code 01H, 02H, 03H, 04H, 05H, 06H, 0FH, 10H
    • Supports at most 48 Modbus commands, Modbus function 03H, 04H, 06H, 10H support byte exchange function, convenient for resolving the format problem of big-endian and small endian between two network data.
  • Under universal mode, support frame timeout, frame length and delimiter control mode, automatic sending function.
  • 1KV galvanic isolated on two RS485 or RS232 interfaces.
  • EtherNet/IP maximum input/output bytes:
    • Maximum input bytes: 492 bytes (Under universal mode, maximum input bytes is 256 bytes)
    • Maximum output bytes: 492 bytes (Under universal mode, maximum output bytes is 256 bytes)
  • Power supply: 24VDC (11V-30V), 90mA (24VDC).
  • Operating Temp.: -40°F to 140°F (-40°C to 60°C); Rel. Humidity: 5%-95% (non-condensing).
  • Dimension (W*H*D): 0.98in*3.94in*3.54in (25mm*100mm*90mm).
  • Mounting: DIN Rail Mounting (35mm).
