     門子PLC前連接器是起接線端子的作用。西門子PLC模塊上沒有接外接信號線的接線端子，所以用專門的前連接器將外接信號線與模塊上的信號線接起來，其實(shí)就是個接線端子排。西門子前連接器是干什么用的,使用帶IO口的模塊一定要使用前連接器嗎，還是前連接器是為了接線方便而使用的。plc內(nèi)部繼電器之所以稱為軟繼電器，是因?yàn)镻LC內(nèi)部有許多具有不同功能的器件，用于實(shí)現(xiàn)數(shù)據(jù)的傳輸運(yùn)算處理存儲。為了把這些元件(如輸入繼電器，輸出繼電器，定時器，計數(shù)器等等)與通常的物理元件區(qū)分開，所以將這些編程元件稱為軟元件。全新原裝西門子編碼器6FX2001-5FD25-1AA0連接器模塊CPU處理器。靜安區(qū)代理模塊連接器6ES7532-5HF00-0ABO
