| Abstract: | In this paper, electric energy meter is connected to computer with the help of RS485 port of the electric energy meter and the PCL-745B data acquisition card from ADVANTECH. Using Delphi language and SPComm communication module, communication program is written in accordance with DL/T645-1997 communication protocol. This paper also discusses some general question of sending communication order and receiving data when designing serial communication program. |
