Modbus Gateways

ModGate 113 ModGate 413 ModGate 813

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.
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).

Modgate is an industrial-strength Modbus-Network gateway for connecting one Modbus line to a network running TCP/IP. It operates without platform and distance limitation.
ModGate uses Modbus/TCP for communication on the network. The serial port is configured for Modbus/ASCII or Modbus/RTU, while the serial line is physically set for RS232 or RS485. The messages received on the network are sent to the serial line, messages from the serial port are sent via network.
The configuration of ModGate is done via HTTP. The user interface is based on Web 2.0 to provide an easy handling of the options. Besides typical serial parameters the configuration includes RS232/485 for serial physical parameters. Further a Modbus address mapping table is available, defining a target port for a certain Modbus address.
ModGate devices are available with up to 8 serial ports, optional also with WLAN plus Ethernet.
