VIII. DLT645 communication description
8.1 Overview
8.2 DLT645 communication address correspondence table
①
This meter is not designed according to the national grid meter specifications. Therefore, only part of the
electrical parameters can be read through the DLT645 protocol. For the specific read parameters, please
refer to the correspondence address table below;
②
The communication data of the national grid is the primary side data without PT and CT. Therefore,
in order to prevent the read data from overflowing, the data of this meter read through DLT645
should be the secondary side data;
③
For specific DLT645 communication protocol, please refer to "DLT645-2007 Multi-function
Energy Meter Communication Protocol"
No.
