Function
Two time values in
hours:minutes:seconds
format are added together. The result is stored in designated variables.
If the addition of two time values results in a value greater than 24 hours, the carry flag M8022 is set to ON and the
actually displayed time is equal to the addition result minus 24:00:00.
If the result is 00:00:00, the zero ag M8020 is set to 1.
