Only part of the totalizer count is shown in the display because it is not possible to output
a 14-digit number. Unit and format of the display are freely selectable, see Fct. 1.04, subfunction
“totalizer” and Sect. 5.5. This determines which part of the count is to be displayed.
Display overflow and totalizer overflow are independent of one another.
