LGS2000-F-DTU180-485-WAPI supports multiple operating modes.
|
||||
| 1、Data transmission mode All data is sent and received through the RS232/RS485 serial port and WAPI wireless, without any conversion, minimizing the complexity for users. |
||||
 |
||||
| 2、AT command mode The DTU180-485-WAPI supports querying and configuring parameters via AT commands on the serial port. |
||||
| 3、Modbus polling mode It can realize the interchange of Modbus RTU and Modbus TCP, and easily realize the Modbus protocol of RS485 bus and TCP network Modbus protocol conversion, so that even traditional equipment can realize safe Internet access. |
||||
 |
||||
| 4、Heartbeat monitoring mode DTU180-485-WAPI Modbus supports serial heartbeat and network heartbeat monitoring. The serial heartbeat packet notifies the serial device that it is active and then actively grabs the device data, typically for monitoring sensor devices that cannot actively push data. sensor devices that cannot actively push data. Notify the server that it is active via network heartbeat packets and maintain a normal connection to the server by continuously sending network heartbeat packets. |
||||
 |
||||
