All PLC output addresses will be set to zero and, since no PLC is
connected, they will remain at zero. Thus, any object controlled by an
output address will always remain in state zero. Similarly, objects that
monitor output addresses will never see the value change.
Objects such as Push Buttons which use a PLC input address will appear to
work normally. However, if they use PLC feedback, that feedback will
never be received.
Static objects that don’t communicate with the PLC, such as Screen
Selectors and Background Text, will operate.
Once the screens are behaving as expected, connect a programming
terminal to the PLC and monitor the PLC’s I/O Data Table. At this stage,
you should connect the PanelView terminal to the PLC, but don’t have the
PLC control any machines or processes.
ATTENTION: Disable all the other I/O racks or modules that
could be affected by the PanelView terminal.
Once all PLC controlled machines and processes have been disabled, you
can put both the PLC and PanelView terminal into Run mode. You’ll need
the reports that the PanelBuilder Development Software generates so you
can correlate each screen and object to the correct PLC address.
Just as you would test a new control panel’s inputs and outputs before
starting up a new control system, so you must run through each screen in
the application file. Use the programming terminal to monitor what
happens inside the PLC as you use each object, and then change the values
within the PLC to see how the PanelView terminal responds.
Test 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 program will respond
safely.
