M ERGING OF D OWNLOAD F ILES
Through a special function in the Post-Processing Window, two Download files can
be merged into a single Destination file. This is a powerful feature that can be used
for generating Before and After type performance plots with HyperPlot.
For example, a pressure and temperature data logging session could be run on a
process prior to process improvements being made. After the improvements have
been made, the logging session could be repeated (using the same Program Net for
comparison consistency). The data from the Before and After sessions could then
be combined into a single file. This resulting file can then be plotted using
HyperPlot. From within HyperPlot, individual plots times can be shifted, allowing for
registration and comparison of the Before and After performance data.
The File Merge Process...
Two Download files can be opened and combined (merged) in the Post-
Processing window as follows:
1. Open the first Download file in the usual manner by
double-clicking on the Open Download File button (or
selecting File/Open Download Data File from the menu
bar).
File Information can be viewed by selecting the File/Data
File Information choice from the Menu Bar.
2. Open the second Download file by selecting File/Open
Secondary Data File from the drop-down Menu Bar. A
second group of Memory icons will display within the
window.
File Information on this second Source file can be viewed
by selecting the File/Data File Information choice from
the Menu Bar and clicking on NO.
3. Drag and drop a Destination File icon onto the
workspace and add connections from the Memory icons
(to be included in the Destination File) to the Destination
File icon.
Double-click on the Destination File icon and specify a
filename and type of file.
4. Click on the Start Post-Processing (green flag) button
and the files will be merged into one Destination File.
Merged File Characteristics
After a Merge of two Download files, the resulting file will contain data and
Channel Names from both the First and the Second source files. However,
additional File Information such as Starting Time/Date, comments, etc. will
be pulled from ONLY the first source file. Additionally, both file’s channel
data will adjusted to start at the same date/time.
