Touch Switches
Reference: If a touch switch with the screen switching function or pop-up keyboard function
is pressed while another touch switch is still being pressed, the key function will
not be executed. Release the other key first.
Switch Functions
The touch switch elements of the PT are arranged in a grid measuring 16 wide by
12 high on the screen. It is possible to create a single large rectangular touch
switch using multiple touch switch elements.
Size of Touch Switch Elements
If any one of the touch switch elements within the set touch switch area is
pressed, this is interpreted as the touch switch as a whole being pressed, and
the set function is executed.
When Show ON State is set, for a moment, the display graphic is displayed in
reverse video when the touch switch is pressed.
Interlock Function
The operation of a touch switch can be controlled (enabled/disabled) from the
PC by setting the interlock function for the touch switch and allocating an inter-
lock bit in a PC data area. The status of the allocated interlock bit is read and its
status determines whether the touch switch is enabled or disabled.
The following table shows how touch switches operate when the interlock func-
tion is used or not used.
The PT continuously reads the status of the corresponding interlock bit while a
touch switch that uses the interlock function is being displayed on the screen. if
the interlock bit’s status changes, the touch switch’s operation is disabled or en-
abled according to the interlock bit’s status.
Touch switches can make the following outputs depending on the processing
function set for them.
Host Notification Function
A bit at the host is overwritten in accordance with the set notification method.

ON. If the touch switch is pressed while the interlock bit is OFF, the
buzzer will sound and the touch switch operation won’t be performed.
The touch switch operation can be performed at any time.
