| Abstract: | A realization of serial communication between PC and PLC can effectively improve the automation control system. The key point to this technology is that a regulation or a rule must be offered for both to observe, that is communication protocol. This paper introduces the PPI protocol and Freeport communication agreement, and the differences between them. The aim is to help consumer know them well and use them efficiently. |
