When deciding what type of key to create, use the following table as a
guide:
General rules about precedence
You can assign a single key to one or more of the three types of key
definitions—object, display, or global. For example, the F2 key can
open a valve when the valve object has input focus, or it can close a
popup display that has focus, or the F2 key can be a global key that
opens a graphic display containing an overview of your process.
When a graphic display is active and an object has input focus, object
keys have precedence over display keys and global keys.
When a graphic display is active, display keys have precedence over
global keys. This means that if you assigned the F2 key as a display key
in some graphic displays in your project, and you assigned F2 as a
global key in the same project, F2 will only work as a global key if the
current display does not have F2 assigned as a display key as well.
When you design your system, pay particular attention to the keys
used by embedded objects. Object keys and display keys have
precedence over keys used by embedded objects (for example,
ActiveX
®
, or OLE objects), except for OLE objects that are not part
of RSView32 (for example, an Excel worksheet), whose keys have
precedence over object or display keys. For details, see the pages that
follow.
