BLIIoT PLC IoT Gateway BL110 Application 50--How Add Watt-Hour Meter to COM Port And Collect Data

Adding Watt-Hour Meter to COM Port

Currently COM?ports can only collect watt-hour meter with DL/T645 protocol. COM1?isRS232. COM2, COM3?and COM4?are RS485 ports. Below is example of collecting watt-hour meter data through COM2 as the meter has RS485 interface.

COM?Port Configuration

Below is example of collecting watt-hour meter with DL/T645-2007 protocol through COM2.

1. Double click COM2 to enter COM attribute configuration box.
2. Select data collection Mode.
3. Select Watt-hour Meter as Device Brand and select DL/T645?as Device Model.
4. Follow Watt-hour Meter COM port parameters to set the same baud rate, stop bit, data bit and parity bit.
5. Click OK to confirm it.

Note: Click Save Data. COM2 port configuration will be effective after gateway restart automatically.

Add Watt-hour Meter to COM?Port

1. Click COM2, right click it and click Add to enter device configuration box
2. Set Device Name at random like ammeter
3. Communication Address: put watt-hour meter communication address
4. Click OK to confirm adding watt-hour meter.

Note: After confirming configuration, ammeter icon will appear below COM2. To add more devices, follow the same steps 1-4 .

Note: Click Save Data. Gateway will restart automatically and adding watt-hour meter is effective.

Add COM Port Watt-hour Meter Datapoint

1. Click ammeter, move mouse cursor to the right box, right click mouse?and click Add?to enter datapoint configuration window.?
2. Set datapoint name, for example, Phase A Voltage.
3. Variable unit: Set any unit as required, can be blank.
4. Address Type: Select the address type?of the meter. For example, Phase A Voltage.
5. Starting Address: N/A keep it blank.
6. Data Type: Select?32-bit single-precision floating data type.
7. Adding Qty:?N/A keep it blank.
8. Read-write Type：Select from Read only.
9. Modbus Mapping Address: Input the address where the collected datapoint is saved in BL110. It can be any address from 0-2000 but can’t be repeated. For example, Phase A Voltage?is saved in register address 17?of BL110.
10. MQTT Flag: can be any identification mark, but can’t be repeated. For example, set REG001 as the MQTT flag of datapoint Phase A voltage.
11. Click OK to confirm.
