我用的是國產(chǎn)仿三菱plc工控板，可是買(mǎi)過(guò)來(lái)廠(chǎng)家給我配制的485通信接口只有兩個(gè)，但是我用的是三菱e740的變頻器，請問(wèn)大家這樣能實(shí)現485通信嗎，能的話(huà)要怎么接呢？生產(chǎn)商只是說(shuō)MODBUS RTU功能的485都可以，三菱的變頻器就不知道了，暈死，他們介紹我用臺達的變頻器，那樣就可以做通信。

遇到這樣的問(wèn)題，你直接叫供應商退回去不就好了嗎！　沒(méi)必要搞的這么麻煩�！∪绻趶V州超盛買(mǎi)的機子，如果不適合用，可以協(xié)商退貨的�！　∠Ｍ軒偷牡侥�！
