比如，我寫(xiě)好了PLC程序，用臺式機將程序寫(xiě)入到PLC控制器中
然后PLC控制器安裝到室外目標地方

過(guò)了幾天，要改動(dòng)PLC程序了，這時(shí)候咋辦？
我買(mǎi)的時(shí)候，PLC連接電腦的線(xiàn)是帶COM端口的，在我臺式機上可以連，可是筆記本上沒(méi)有COM端口，沒(méi)地方連接啊
總不能每次都把臺式機搬到目的地去吧？

請教各位，是怎么處理的？ 還是我接線(xiàn)有問(wèn)題？想想嘛，筆記本應該也可以連接才對，可是愣是沒(méi)找到插入的地方。


外行請教。

買(mǎi)條USB轉232通訊線(xiàn)就好了。淘寶上大把的。
