Special Features

1.Modbus Polling Mode
In this mode, it supports Modbus TCP and Modbus RTU mutual conversion.
2. Heartbeat Packet Function
USR-W630 supports network heartbeat packet and serial heartbeat packet. The network heartbeat packet notifies the server that it is in an active state, and it maintains the normal connection with the server by continuously sending the heartbeat packet.Serial port heartbeat packet notifies the serial device that USR-W630 is in an active state, and takes the initiative to grab the sensor data can not be initiative to push.
3. Socket Distribution Protocol
USR-W630 suppports SDP, you can add certain header in serial data. It will send the data to differetnt socket by different header. The data received from different
socket will be added different header before they are sent to serial.
4. Regular Restart Function
USR-W630 supports timing and timeout restart function, which makes the system run more stable.
