7. If you clicked the Temporary Monitor Set button in step 6, a dialog
with a tree view of the AppDevice objects installed on your network will
open. Select the AppDevice object containing the network variable(s) you
want to monitor.
A temporary monitor set will be created containing a network variable
monitor point for every network variable on the devices main and custom
interfaces.
For source information and specific properties set for these objects see
CPrimaryFormDlg::OnTemporaryMonSet() in the
PrimaryFormDlg.cpp file. Also, see the TempMonitorSetDlg.cpp file.
8. If you clicked the Permanent Monitor Set button in step 6, a dialog will
display allowing you to open one or more permanent monitor sets. For
source information, see CPrimaryFormDlg::OnPermanentMonSet() in
the PrimaryFormDlg.cpp file, and the PermMonitorSetDlg.cpp file.
9. Once you have completed step 7 or 8 and created a monitor set, you can
choose from the following options:
• Click the Query Device Status button to query the status of the
devices using the message monitor points available in the currently
selected monitor set.
• Click the Toggle Monitoring Button to enable or disable monitor
points.
• Click the Set Value button to write to the value of an input network
variable monitor point.
