摘　　要：介绍了西门子PLC S7-300[1]系统和iFIX[2]上位机软件的通讯及两者之间的结合在远程通讯中的应用,兼于两点异地罐区和装车区不在同一地点,且距离较远,要想实现自动装车就必须让罐区仪表和装车系统通讯起来,本文讲述的是罐区仪表可以实现在装车区控制,且只用一对光纤和两端的设备就能实现两者之间的通讯,既避免了由于距离远仪表电缆信号衰减情况,又节约了成本。In this paper, we introduce Siemens PLC S7-300[1] system and iFIX[2] host computer software, communications and their combination in remote communication application. For two different tank and loading in the same place, to realize automatic loading must keep the tank instrument and loading system communicated. We use the instrument in tank to realize communications , based on only a pair of optical fibers and the ends of the equipment, which avoid cable signal attenuation, and save the cost。
