Modbus Gateways connect a network with serial Modbus lines. They convert Modbus/TCP on the network to Modbus/RTU or Modbus/ASCII on the serial connection. The serial line may operate by RS232 for a single device, or in RS485 mode to connect with many devices. As one extension also RS422 is implemented. And as second extension the ModGate support multiple Modbus Masters on TCP or serial connections. This platform with ARM9 RISC-Processor provides Ethernet or WLAN connection plus up to eight serial ports with high speed UART 16C950 (128 Byte FIFO).
