I would do this
AN "Alarm WZI Actief"
O "Reset Vanaf de WZI"
FN M 21.1
R C 10
Otherwise if "Alarm WZI Actief" was on and "Reset Vanaf de WZI" was off, you may still reset, as the RLO could be anything at the start, if it is '1', then the ON "Alarm WZI Actief" will allow the RLO to remain on and you would reset at the incorrect time.
