1。你的電路太簡單,完全不需要用到編程器PLC,而且編程器PLC價值不菲,除非你另有目的,不然還是不要改用編程器PLC。

2。你不能在這個電路内加任何的緊急停機開關,因爲就算你將電源切斷,那個氣缸/油缸(Cylinder)還是會收縮動作到頂底爲止,除非你改用雙控閥。

2012-10-27 10:23:18 補充:
如果你堅持要用PLC,I/O 接線如下


Com = +24V out
X0 = E. STOP - NC
X1 = Auto ON - NO
X2 = forward STOP = LS-1 - NO
X3 = backward STOP = LS-2 - NO

2012-10-27 10:23:30 補充:
Com = +24V IN
Y0 = emergency stop / immediately stop indicator lamp
Y1 = cylinder forward driver signal
Y2 = cylinder backeard driver signal
Y3 = forward indicator lamp
Y4 = backward indicator lamp


你還要寫編程,工程浩大啊。

你重點在那那都可隨便編
可見你...........作業
真是滴....不長進...連最基本滴你都不看
