Restrictions

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 425).

gon can be given up to 255 vertices.

pressed, all of the touch switch functions will be executed. Except for functions
communicating to the host, only one function can be executed at a time, so just
