最近做了一個(gè)項目，設備改造的，之前的電氣系統很老舊了，用的子門(mén)子318plc做的，想升級為1200plc，項目大約有50個(gè)變頻器，6個(gè)絕對值編碼器之前都是掛在profibus總線(xiàn)下的，現在碰到一個(gè)問(wèn)題，之前用的編碼器很舊了且是進(jìn)口的，已經(jīng)找不到說(shuō)明書(shū)了，但是市場(chǎng)上好像很少有支持profibus dp的絕對值編碼器，于是想用485通信的編碼器代替，如何將485通信的變啊默契掛到profibus總線(xiàn)下面，我看某寶有485轉profibus的模塊 不知是否穩定？有哪位大神給點(diǎn)建議啊
