PSR-SPP-24UC/ESA4/2X1/1X2為了讓大家更好的理解，我們舉個簡單的例子。比如說現(xiàn)在有一臺空調(diào)，它是通過PLC控制的。這臺PLC的程序是外界溫度低于20攝氏度時空調(diào)制冷關閉，超過20攝氏度時打開。既然涉及溫度了，肯定PLC需要采集溫度信號，一般都是input接口連接一個溫度傳感器什么的。隨著外界溫度的不斷上升，從5度10度一直提升到20攝氏度，相應的信號傳達到PLC里，根據(jù)程序發(fā)出打開空調(diào)的指令，指令通過OUTput接口到底空調(diào)開個那里，這個開關應該是個模擬量開關，會持續(xù)的打開。當空調(diào)不斷制冷，室內(nèi)氣溫逐步下降，氣溫降到20攝氏度以下后，PLC根據(jù)新的采集到的信息，發(fā)出關閉空調(diào)的指令，空調(diào)關閉，氣溫再次逐步上升，由此循環(huán)往復，從而實現(xiàn)空調(diào)的智能化降溫。
不管是哪種型號的PLC，它們都會集成通訊模塊進行IO擴展或者是與上位機連接，從而實現(xiàn)更多的操作。老式的PLC一般只有以太網(wǎng)接口以及串口接口，CAN接口的很少，想要擴展需要花費大筆銀子，尤其是西門子這樣的國外廠家，做好挨宰的準備就對了。而廣成科技開發(fā)自帶CAN總線的PLC，完美滿足您的需要，如果想要的話，歡迎加微信183-0981-5706進行咨詢。
