With DT80 G I have to measure time (let say in seconds) for which one digital input is in the status ON (how long it stays ON). Once when it goes OFF time has to be reset i.e. set to 0. It is not clear to me how to do this.

Hi sjankovi,

There are multiple methods to measure time on digital status changes:

1. Using manual counting

RA1S
IF(1DS==1){1CV=1CV+1}
IF(1DS==0){XB 1CV=0}

RBX
1CV("Time~s")

1. Using Edge timing Edge timing TFR will measure the last rising value to the present falling value

RA1E
1DS
1DS(TFR,"Time~s")

Best regards,
