A maximum of 256 touch switches can be registered for one screen. (Same for
window screen.) For overlapping screens comprising 8 child screens, the
maximum is 256 per screen.
There is no restriction on the number of touch switches that can be regis-
tered for one screen data file: any number can be registered as long as the
data file capacity is not exceeded. However, if a large number of elements
are registered, check that the restrictions on element display are complied
with by referring to Display Restrictions (page 431).
