1756-CN2R+++1756-CN2R上位鏈接通信
上位鏈接包括兩個(gè)方面,即從上位計(jì)算機(jī)到plc和plc到上位計(jì)算機(jī)。在前者中,對(duì)于cpu單元,從上位計(jì)算機(jī)發(fā)布上位鏈接指令(c模式指令)或fins指令,進(jìn)行plc的i/o存儲(chǔ)器的讀寫(xiě)、動(dòng)作模式的變更及強(qiáng)制置位/復(fù)位等各種控制。在后者中,對(duì)于上位計(jì)算機(jī),從cpu單元發(fā)出fins指令,發(fā)送數(shù)據(jù)和信息。在上位計(jì)算機(jī)中,監(jiān)視plc內(nèi)的運(yùn)行結(jié)果數(shù)據(jù)、異常數(shù)據(jù)、指令數(shù)據(jù)或?qū)lc指示生產(chǎn)計(jì)劃數(shù)據(jù)信息。進(jìn)行上位鏈接時(shí),可以通過(guò)plc系統(tǒng)設(shè)定將串行端口的串行通信模式設(shè)為上位鏈接通信(串行端口1、2都可以)。
