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.
  • Dual Ethernet ports with built-in Ethernet switching functionality, supporting cascading connections.
  • Supports the ODVA Standard EtherNet/IP communication protocol.
  • Supports Non-DLR functionality and can be directly integrated into a DLR ring network.
  • Two serial RS-485 interfaces, half-duplex, and baud rate support: 300,600,1200, 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,17H function codes, can be configured up to 100 Modbus commands for each RS-485 interface;
    • Function: Cycle output, Disabled output, Change of value and Control word trigger;
    • Modbus function codes 03H, 04H, 06H ,10H and 17H support the "Byte Swap" function, and it can help users solve the problem of data format between two different networks.
  • The maximum number of input and output bytes of EtherNet/IP:
    • Maximum number of input bytes: 492Bytes.
    • Maximum number of output bytes: 492Bytes.
  • Power supply: 24VDC (9V ~ 30V), 110mA (24VDC).
  • Working temperature:-4°F to 140°F (-20°C to 60°C); Rel. Humidity 5%-95% (non condensing).
  • Dimension (W*H*D): 1 in*4 in*3.6 in (25mm*100mm*90mm).
  • Installation: 35mm DIN rail.
