Program explanation
1. When DA is TRUE, the value of RxVar1 is 1000, DVP04DA’s channel 1 outputs 2.5V voltage, the value
of RxVar2 is 2000 and DVP04DA’s channel 2 outputs 5V voltage.
When DA is FALSE, the values of RxVar1 and RxVar2 are both 0 and DVP04DA’s channel 1 and
channel 2 both output 0V voltage.
2. When AD is TRUE, TxVar1~TxVar4 are assigned to AD_CH1~AD_CH4 to read the present values of
channel 1~ channel 4 of DVP04AD-S.
3. When D_OUT=ON, the value of RxVar3 is 16#FF (255) and DVP16SP11T is controlled to change its
Y0~Y7 to ON.
When D_OUT=OFF, the value of RxVar3 is 0 and DVP16SP11T is controlled to change its Y0~Y7 to
OFF.
4. When D_IN=ON, TxVar5 is assigned to SP_IN1 to read the values of DVP16SP’s input points X0~X7.
