Product Introduction

Our company'sData Acquisition Gateway(Data Collection Gateway, abbreviated as)DAGGateway is mainly used inModbus RTUProtocol data andModbus TCPConversion between protocol data. Serial port supportModbus RTUMaster and slave functions, supported on Ethernet endModbus TCPFrom the station function.
Serial port operationModbus RTUDuring the main station, users can be actively collectedModbus RTUThe data from the slave station is saved in the data buffer, and the userModbus TCPThe main station equipment can read and write data buffer through Ethernet port to achieveModbus TCPThe main station andModbus RTUThe function of data exchange between slave stations.
Serial port operationModbus RTUFrom the station, the user'sModbus RTUThe main station device can read and write data buffers through the serial port,Modbus TCPThe main station equipment can also read and write data buffers through Ethernet ports to achieveModbus TCPThe main station andModbus RTUThe function of data exchange between main stations.
Users can use the delivery serviceDagctoolSoftware（PCEdit serial port parameters, Ethernet port parameters, working modes, andModbus RTUInstructions, etc., downloaded through Ethernet portDAGWithin the gateway. It can also be accessed through an Ethernet portDAGExisting interface parameters within the gateway andModbus RTUCommand upload toDagctoolSoftware. Users can combine these interface parameters withModbus RTUSave instructions as files for other purposesDAGGateway device usage.

Features

1ModbusRegister address mapping to achieveModbus TCPQuick response to requests.

2. User definedModbus RTUInstructions.

3. The instruction sending interval, response timeout, and slave response delay can be set.

4. Support2A serial port that can be used simultaneouslyModbus RTUMaster station or slave station.

5. Supports the most5 aModbus TCPMain site accessDAGGateway.

6. Interface parameters andModbus RTUInstructions can be saved as files, reducing user configuration time.

7. DeliveryWINDOWSThe configuration tool software has a user-friendly interface and simple operation.

8. The error diagnosis function can monitor the communication status of the slave station equipment in real time and quickly eliminate faults.
