一臺S71200帶350臺485通信的流量計，車(chē)間流量計303臺，加藥中心流量計28臺，每個(gè)流量計讀2個(gè)數據，瞬時(shí)流量和累計流量，PLC不需要做輪詢(xún)程序，使用巨控GRM300協(xié)議網(wǎng)關(guān)，帶4個(gè)485，1個(gè)RS232，每個(gè)通訊口接10臺流量計，提高處理速度，每個(gè)通訊口是獨立的不會(huì )相互干擾，把讀到的流量計數據，再往1200 PLC寫(xiě)，這里的協(xié)議網(wǎng)關(guān)是做為S7 TCP主站，所以直接寫(xiě)入PLC即可。

    你這樣帶也是帶50個(gè)流量計，不是要帶350個(gè)流量計嗎？
