現在有一臺FX5U32MR與GT2310以太網(wǎng)通訊，通訊不上。我的網(wǎng)線(xiàn)長(cháng)度為30米，網(wǎng)線(xiàn)接法一頭A類(lèi)型一頭B類(lèi)型。點(diǎn)擊觸摸屏沒(méi)反應，換了2跟網(wǎng)線(xiàn)都沒(méi)用。然后我用短的網(wǎng)線(xiàn)連接通訊正常。請教一下這是為什么?打電話(huà)給客服，客服說(shuō)100米以?xún)榷际强梢缘�。是不是我設置問(wèn)題還是什么？還有一臺Q系列的PLC也是這個(gè)問(wèn)題。是不是觸摸屏設置的哪里不對？

都用B頭接法，也就是普通網(wǎng)線(xiàn)的接法，不能用交叉接法。
樓主留言：
普通接法，網(wǎng)線(xiàn)短還能通訊上，長(cháng)就不行了
