Module Description
The dlt645 protocol supports serial and tcp connection.
Parameter Configuration
Serival
| Parameter | Description |
|---|---|
| timeout | Timeout for sending requests to the device |
| inteval | read instruction interval(ms) |
| device | Use a serial device, e.g. /dev/ttyUSB0 |
| stop | stopbits, default 1 |
| parity | parity bit, default 2, which means even parity |
| baud | baudrate, default 9600 |
| data | bytesize, default 8 |
TCP
| Parameter | Description |
|---|---|
| timeout | Timeout for sending requests to the device |
| inteval | read instruction interval(ms) |
| host | When neuron is used as a client, host means the ip of the remote device. When used as a server, it means the ip used by neuron locally, and 0.0.0.0 can be filled in by default |
| port | When neuron is used as client, port means the tcp port of the remote device. When used as a server, it means the tcp port used by neuron locally |
| connection mode | The way the driver connects to the device, the default is client, which means that the neuron driver is used as the client |
Supported data types
- UIN8
- UINT16
- UINT32
- UIN64
Usage of Address Format
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.
