Example
When R020 is ON, the date and time data recorded in D0050 to D0055 are subtracted from the current date and time of clock/calendar, and the result is stored in D0100 to D0105.
In normal operation, the output is OFF (R0035 is OFF). If D0050 to D0055 contains invalid data, the operation is not executed and the output is turned ON (R0035 comes ON).
