If you are using another PanelBuilder application file, you will have to use
your own PLC application program for whatever PLC controller you are
using.
At this stage, connect the PanelView 1200 terminal to the PLC controller,
but don't have the PLC controller control any machines or processes.
Refer to your scanner and PLC controller manuals for information on how
to create scan lists that include all rack assignments for the PanelView
1200 terminal.
Once all PLC controlled machines and processes have been disabled, you
can put both the PLC controller and PanelView 1200 terminal into Run
mode, if you haven't already done so.
Run through each screen in the application file, just as you would test a
new control panel's inputs and outputs before starting up a new control
system. Use the programming terminal to monitor what happens inside the
PLC controller as you use each object, and then change the values within
the PLC controller to see how the PanelView 1200 terminal responds.
Switch the PanelView 1200 terminal to Configure mode and back to Run
mode. You should also remove and re-apply power to the PLC controller
separately, and to the entire control system to ensure that the system
re-initializes as expected.

Testing Retentive Objects

Observe each object carefully if you are using any retentive input objects.
Switch the terminal off and on again, and switch it to Configuration mode
and back to Run mode. Watch the input addresses for each retentive object
to ensure that the values are initialized so that the the program will respond
safely.
Once you've checked all PLC values and determined that all objects,
windows, and PLC controlled functions communicate properly with the
PLC, you're ready to set both the PLC and the terminal into Run mode and
test your application file in action.
