Communication Protocol Macro Application in PLC Control

Article Preview

Abstract:

This article from the glass batching control system and communication software two respects introduces a kind of design scheme based on RS-485 communication. The program is mainly based on RS-485 communication protocol and uses CX-Protocol software to write process procedures to meet user needs. This will not only achieve the communication purpose between programmable controller and instruments but also can monitor the operating status of each instrument, at the same time data tracking results also show a higher accuracy.
