Archive A decision is made whether the trend data Archiving is to be effected on
the operator station. If Archiving is activated, specify the following: Ar-
chive duration, Start up mode and if the old archive data should be de-
leted. On the operator station only one trend display with a fixed size con-
figured for an archive file (as ring memory).
Enable Archiving
The trend data are archived as a function of the Start up mode.
Delete old archive
The old archive will be deleted on restarting the operator station (new
start of DigiVis).
Archiving is resumed with a chronological gap after a restart.
If archives do not match after a restart, e.g. the number of trends
have changed in the meantime, the old archive is saved as a file.
The old archive files are assigned a serial extension from 001 to
999.
Archive duration The Archive duration is entered according to the IEC 1131-3 time format.
The entry can be made in days, hours, minutes and seconds. Inputs less
than 1 s lead to error.
Maximal 24855d = 68 years
