| Abstract: | PROFIBUS is open, mature technology used to exchange message between automation system and decentralized field devices. PLC is a typical master of PROFIBUS.S7-200 miniature PLC may finish complex control by net, decentralized system and give play to real time in FCS.The PPI protocol giving the form of PPI protocol and the software chart about PROFIBUS slave remolding are studied,and the communication between PROFIBUS slave and S7-200 PLC is realized.The working ability of system and its safety is improved.The method,which is economical and convenient can be used in projects. |
