What to expect when you open a web application

To open a published web application, all you have to do is open a browser and enter
the address of the computer or terminal running the web server that hosts the
application, such as http://computer name/FTVP.

The initial display that you specified for the web application opens first. From there,
you can navigate the entire application using buttons and touch animation created in
FactoryTalk View Studio. Touch animation is not supported in FactoryTalk
ViewPoint for Machine Edition.

Displays in a FactoryTalk ViewPoint application can be secured. In runtime, an
authenticated user who is a member of a security group, is allowed or denied access
to secured displays. There are two types of access: Write and View. Graphic objects
in the displays are fully animated; and depending on your security permissions you
can use the objects to write to tags. You cannot start and stop HMI components. For
example, a numeric input object with a tag connection will display the tag's current
value, but will not permit downloads.

As in FactoryTalk View, objects with tag or expression connections will show in
outline form if the connection is broken.

To learn more about FactoryTalk View features that are not supported in FactoryTalk
ViewPoint applications, see the FactoryTalk ViewPoint Help.

When you enter a web address in the browser, do not exceed the maximum length of
2048 characters. Rework the screen so that the web address is less than 2048
characters. If the web address exceeds the maximum 2048 characters allowed, the
following error message appears, "Unable to open the requested display. The web
address exceeds the maximum length of 2048 characters".
Note: Different browsers have different length limits. If you get this error message
because you are using large numbers of parameters, it is recommended that you use
a parameter file instead.

If you are using FactoryTalk ViewPoint Site Edition, you can view multiple displays
using a startup macro. FactoryTalk ViewPoint Machine Edition allows a single display
on startup. Macros are not supported in FactoryTalk ViewPoint for Machine Edition.
