NOTE
The frequency converter has no back up of the clock
function and the set date/time will reset to default
(2000-01-01 00:00) after a power down unless a Real Time
Clock module with back up is installed. Consequently, the
logging will be stopped until date/time is readjusted in
0-70 Set Date and Time. In 0-79 Clock Fault it is possible to
program for a Warning in case clock not has been set
properly, e.g. after a power down.
