Apart from the input field for the archive duration, the maximum hard disk
requirements for archiving on the operator station are given in kilobytes.
The size of the trend file is determined by the archive duration.
This size can never be exceeded by the Trend file since data are
stored in a ring memory. This means that on reaching the archive
duration, the oldest data are always overwritten again by the current
data.
The Start up defines whether trend data recording and archiving should
start immediately after starting DigiVis.
Acquisition and archiving are ready but not yet started after starting
the operator station. Start is triggered by changing a flank at one input
of the trend acquisition module. See Engineering Reference Manual,
Functions and Function Blocks, Acquisition blocks.
Acquisition and archiving are switched on after starting the operator
station.
The file name for the trend archive file on the operator station hard disk
can be specified.
