  西門(mén)子1214C  DCDCDC 大概什么價(jià)格，然后的話(huà)西門(mén)子1214C  的IO點(diǎn)數很少，西門(mén)子的擴展模塊又很貴，我能不能用一個(gè)  相對好一點(diǎn)的 國產(chǎn)PROfinet  模塊后面擴展IO端子的方式節約成本？ 沒(méi)試過(guò)這種用法，問(wèn)問(wèn)大神能不能實(shí)現？  大概200點(diǎn)左右，然后一個(gè)Prifinet  遠程IO 能加多少個(gè)IO點(diǎn)？有沒(méi)有限制

西門(mén)子的CPU只能擴展西門(mén)子的模塊吧？國產(chǎn)的？能匹配嗎？
