PLC點陣鍵盤
在工控行業(yè)中，有時候會碰到因為可編程控制器（PLC）輸入點的不夠，而導(dǎo)致需要更換設(shè)備，浪費資源。對此，當(dāng)實時性不需要那么高時，我們可以編寫一個鍵盤的掃描程序來擴展輸入的點數(shù)。因為掃描的方式是循環(huán)掃描，所以在實時性方面會有一定的欠缺。
下面是用海為PLC編程軟件編寫的8乘6的48鍵掃描程序。需要用到8個輸入點，6個輸出點，硬件連接如下圖所示：
注：當(dāng)要求實現(xiàn)組合按鍵時上圖的二極管必須加，反之二極管可加可不加。
掃描的點是令Y0~Y5循環(huán)輸出，當(dāng)有按鈕按下時，就會做出相應(yīng)的動作，例如：當(dāng)按鈕鍵0按下時，則X0接通，當(dāng)程序掃描到Y(jié)0時，X0與Y0形成一個回路， 表示按鍵“0”按下。程序如下圖所示：
結(jié)論：鍵盤是以循環(huán)掃描的方式來進行輸入，而掃描的時間越短則實時性越好。但是當(dāng)掃描時間過短時會因Y0~Y5輸出結(jié)束時，X0仍未接通導(dǎo)致無法產(chǎn)生輸出信號?；蛘弋?dāng)Y0輸出結(jié)束，Y1也輸出結(jié)束時，X0仍未斷開，導(dǎo)致誤判斷。
經(jīng)過型號SW-S32ZS220T測試可知每次循環(huán)掃描的時間T0不得低于20ms。建議可將濾波時間設(shè)得短一點，則可以縮短每次循環(huán)掃描的時間T0，例如：本例中將濾波時間設(shè)為0.8ms，則每次循環(huán)掃描的時間T0可以設(shè)到***短10ms。
