之前沒(méi)有用過(guò)1500，有個(gè)項目客戶(hù)指定要用1500的PLC，項目大概情況是現場(chǎng)有50多個(gè)測試工站，每個(gè)工站有對應的控制點(diǎn)位，數據采集，但是項目預算有限，所以想用一個(gè)1500的CPU通過(guò)以太網(wǎng)通信走M(jìn)ODBUS-TCP協(xié)議連接現場(chǎng)50多個(gè)站點(diǎn)，現場(chǎng)50多個(gè)站點(diǎn)采用國產(chǎn)帶網(wǎng)口的PLC，獨立控制每個(gè)工站的邏輯控制，數據采集，主站的1500只負責實(shí)時(shí)去下面每個(gè)工站讀取采集到的數據，下發(fā)開(kāi)機、停機命令。這樣的方案可行嗎？另外如果可行的話(huà)主站的1500是不是只需要電源加CPU就可以了，不需要再擴展IO模塊那類(lèi)了。
請大神們指點(diǎn)一下。謝謝！
當激情不在的時(shí)候，我們還剩下什么？
