hello. Im new to using omron and im wondering how to use analog inputs and convert them into digital outputs. we are using an omron cj2m cpu11, with mad42 as our analog i/o module, id211 and oc211 as our basic i/o. Our task is to use a lidec l20d and a light to indicate that  there is water on the lidec. the lidec sends out 6 mA when its out of water and 18 mA when its in water. the problem is that i don't know how to use any analog inputs in general so all help would be appriciated thanks
