DL/T645-2007

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.

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.
