The dialog shows the available process variables that have been stored in the project
database as a result of browsing or self−definition. The structure of the hierarchy
shown here is basically the same as the structure in Project Explorer.
"Internal" indicates variables that have not been assigned to any communication
channel, and that are not mapped realistically in a control system. Nevertheless, these
variables can be needed within a visualisation application in order to trigger e.g.
variable−controlled processes or can simply be needed as a buffer for values from the
visualisation application.
"DemoChannel" or "External"contains the variables that are mapped in the PLC. The
communication channels are listed under "External". Under this area are the name
spaces that have already been using during browsing.
8. Select the variables whose value you want the control element to show (e.g.
"Internal"
®"__System" ®"Time") and then click OK.
Specifying the VWItem property causes a change in what is shown in the "VarOut1"
control element. When the process variables to be shown are specified, the type of data
is interpreted. The value shown in the control elements jumps to a value that simulates
what is shown during the runtime. This makes it possible as early as the development
time to check whether the control element can show the value completely or whether
the dimensions of the control element have to be modified.
9. Select the VarOut control element and scale it until the clock time is shown.
10. Save the form by clicking the menu item File
® Save and then look at the results by
pressing [F5] to start the project.

Note!
If you are working in demo mode (without dongle), an information dialog is
displayed every time the runtime system is started. Close it with the OK
command button.
