Pen Backups
Pen backup settings are special settings used to fill in “critical” missing data when there
is a compatible alternate data source. Compatible data sources could be backup servers
running SDIO independently. SDRecorder will use the primary source and fill missing
data with data from the backup source.
Pen Backup Settings
BuEnable – Enables the use of the backup data source. This is normally false and
must be set to true to use the backup data. This would normally only be done when
there is essential missing data. The Bu Directory, Bu TID and Bu Tag Expression must
be set in order to set BuEnable to true.
BuDirectory - This is the “Alternate Data” directory containing the backup data source.
This directory could be a local directory or a network share. The directory must contain
the intparms.xxx files, the comdata, log and clog subdirectories. The comdata
subdirectory must contain the inttbl.dat file and the log and clog directories must
contain the hourly and compressed data files as desired.
BuTID - This defines the Backup TID. If the primary TID is based on a Channel/Slot
then this BuTID will be selected from a Tag Selector dialog based on the Alternate data
source. If the primary TID is a derived TID, then this BuTID will be the same as the
primary TID (but using a different tag expression).
BuTagExpression –If the BuTID is derived, the Expression Editor will be used to
generate the expression. The Expression Editor will use tags from the alternate data
source.
