Abstract:

This paper describes the principle of longdistance network measurement and control system, introduces a way of communication between PC and PLC in the long distance network measurement and control system. With the HostLink communication protocol which belongs to OMRON, serial communication between PC and PLC is realized by using of MSComm component under Delphi 7.0 environment.

Key words: serial communication, PLC, Delphi 7.0, network measurement and control
