To keep the Upload Scheduler running, the 'On-line' button
on
the toolbar must be checked all the time. If you uncheck it, the
scheduler will stop operations. This will not cause loss of data, since
the scheduler will resume operations when you check this button again.
Suspending the Scheduler
To suspend the Upload Scheduler, check the 'Suspend Scheduler' box at right. To
activate the Upload Scheduler, leave this box unchecked.
Running the Scheduler on Demand
You can run the scheduler at any time outside the schedule by checking the 'Start
Now' box at right. This is a one-time action. After uploading is completed, the
Upload Scheduler will uncheck this box automatically.
Recording Upload Problems
When the Upload Scheduler fails to retrieve data from the meter, or some data is
missing, or another problem occurs, it records an error message to the log file. To
review this file, select 'Log Window' from the 'View' menu.
Viewing Historical Data On-line
ometimes, it is useful to review a particular historical data on-line at the time
you expect the new events to appear in the log. PAS allows you to retrieve
historical data from a particular log without storing it to a file. The data
appears only in the window on your screen. If you want, you can save it
manually to the database.
To view a historical log on-line, select from the 'Logs' menu the log you want to
retrieve, check the 'On-line' button
on the toolbar, and then click on the
'Single poll' button . Only new log records will be retrieved from the meter. If
you want to review the log from the beginning, click on the 'Restore Log' button
on the toolbar, and then click on the 'Single poll' button
.
There is a difference between retrieving waveform logs on-line and viewing
waveforms from a file. The waveforms are read one record a time, so that a multi-
record waveform series may not be viewed in this mode as a single waveform.
For information on using different log views, see Chapter 5, 'Viewing Log Files'.
If you decide to view historical data on-line, make sure you leave
unchecked the box 'Do not scan entire file' in the 'Select Logs' dialog
when configuring the automatic uploading (see Note in section 'Uploading
Historical Data on Demand'); otherwise, you may discover that the last logs are
missing from your log files.
