DL/T645-2007

DL/T 645-2007 is a multifunctional electric energy meter communication protocol used primarily in power systems for single-phase and three-phase meters. It supports various communication methods, including wired (e.g., RS-485) and wireless (e.g., GSM/GPRS).

The Neuron DLT645-2007 plugin provides connectivity with DL/T 645-2007 devices through serial ports and TCP.

Add Device

Go to Configuration -> South Devices, then click Add Device to add the driver. Configure the following settings in the popup dialog box.

• Name: The name of this device node.
• Plugin: Select the DLT645-2007 plugin.

Device Configuration

After clicking Create, you will be redirected to the Device Configuration page, where we will set up the parameters required for Neuron to establish a connection with the northbound application. You can also click the device configuration icon on the southbound device card to enter the Device Configuration interface.

Configure Data Groups and Tags

After the plug-in is added and configured, the next step is to establish communication between your device and Neuron by adding groups and tags to the Southbound driver.

Once device configuration is completed, navigate to the South Devices page. Click on the device card or device row to access the Group List page. Here, you can create a new group by clicking on Create, then specifying the group name and data collection interval.

Upon successfully creating a group, click on its name to proceed to the Tag List page. This page allows you to add device tags for data collection. You’ll need to provide information such as the tag address, attributes, and data type.

For information on general configuration items, see Connect to Southbound Devices. The subsequent section will concentrate on configurations specific to the driver.

Data Types

• UIN8
• UINT16
• UINT32
• UIN64

Address Format

mail_address#DI3-DI2-DI1-DI0

• mail_address represents the mailing address of the meter.
• DI3-DI2-DI1-DI0 represents the data identification, and all points only support read attributes, and expressed in hexadecimal.

E.g 123456789012#02-01-01-00, represents the value of the A-phase voltage of the meter device with the mailing address 123456789012.

TIP

Support a node to configure multiple mailing addresses, that is a single serial port multi-device connection.

Please refer to the DL/T645-2007 industry standard data coding table for the specific data item name corresponding to the data identifier.

• The data length is 1, and the data type is UINT8.
• The data length is 2, and the data type is UINT16.
• The data length is 3 or 4, and the data type is UINT32.
• The data length is 5 or 6 or 7 or 8, and the data type is UINT64.
• Set the value of Decimal according to the data format, e.g, if the data format is XXX.X, then Decimal is set to 0.1.
