       大家好，本人剛踏入工控行業(yè)不久，在這虛心請教各位朋友們，最近在做一個(gè)換熱站的標書(shū)，招標文件有這么一句“控制能支持MODBUS TCP，可以用光纖與熱電廠(chǎng)DCS進(jìn)行數據交換”想請教大家這里進(jìn)行硬件選型的時(shí)候應怎么選擇，記得有個(gè)模塊可以把數據轉換成光纖輸出，西門(mén)子有這個(gè)模塊嗎？如果不對，那這個(gè)地方應該怎么配置呢！謝謝大家

我沒(méi)寫(xiě)過(guò)PLC程序
但是根據我菜鳥(niǎo)的理解 這里所謂的光線(xiàn)進(jìn)行數據交換貌似就是普通的以太網(wǎng)通信吧....你可以用OPC吧。。
希望高人有更好見(jiàn)解  初來(lái)乍到多多關(guān)照
