摘要
采用实时无线PPI通信模块SY-S72,通过OPC软件PC Access上位机的组态软件,实现了多个提升、排海泵站和中控室的实时通信。研究了PPI协议的通信时间开销,并和现有的其他方案进行比较。
The real time communication among lift pump, exhaus t pump and central control room are implemented through real time PPI communication module SY-S72 and configuration software of PC Access host computer OPC software. The communication time cost of PPI protocol are studied and compared with existing schemes.
