Function overview:
Example for SETTOT and MODETOT:
If the SETTOT parameter is set to 1 (= reset the totalizer), the value for the aggregated totals of the
totalizer is reset to 0. If the aggregated totals of the totalizer should constantly retain the value 0,
the MODETOT parameter must first be set to 3 (= totalising is stopped) and then the SETTOT
parameter must be set to 1 (= reset the totalizer).
