monitor are described below.
Open Log File
Before you can monitor and collect the historical buffer for a
process historian function block you must first open a log file.
Choosing Open Log File from the File Menu opens the dialog
box shown in Figure 20.
Figure 20. Process Historian: Open Log File.
In the Open Log File dialog, select the Drive, Directory, and
File Name that you want to open. When you are through
choose OK to close the dialog and return to the Process
Historian monitor window.
If the file that you specified is a new log file, you will be
prompted to create it. Choose YES in the prompt dialog to
continue and create the new log file.
After you have opened a log file, a line will appear at the top of
the Process Historian Monitor window. If the log file is a new
file the line will show an entry:
[Log File]
If the file you opened already exists, then the line will show an
entry similar to:
[Last entry before closing: 21:45:18.315 on 03/15/1994]
This indicates the time stamp of the last recorded variable
entries stored in the opened log file.
