| Abstract: | The article describes the Selection and realization of the communication modes between CompactLogix PLC and EVIEW humar： nachine interface（HMI） . It also introduces the differences from two kinds of I/O address assignment method for stock PLC. A method named address mapping is presented to solve the problem in which EVIEW （HMI） is uncompatible with CompactLogix PLC. It overcomes the limitation that people have to select the specified HMI to connect with PLC. The flexibility of selecting the hardware in practice project is improved greatly and the cost is reduced. |
