The MGate MB3000 gateways effectively connect a high density of Modbus nodes to the same network. The MB3280 manages up to 62 serial server nodes; the MB3480 manages up to 124 serial server nodes. Each RS-233/422/485 serial port can be configured individually for Modbus RTU or Modbus ASCII operation and for different baudrates, allowing both types of networks to be integrated with Modbus TCP through one Modbus gateway.
