2-2 Part Names and Functions
Touch Panel (NS15)
The touch switches on the front panel of the PT are used to perform input operations. Press
the touch switches to perform operations such as switching screens and sending bit status to
the host.
Function
performed
To ensure correct input operations, create touch switches so that they consist of at least 32 x
32 dots.
The NS15-TX01@-V2 uses an analog touch panel.
Never press more than two points on the panel at a
time. Otherwise, it may activate a switch some-
where between the two points.

Reference

Functional objects can be created combining
minimum size switches.
When a functional object is pressed, its function is performed.
• Press the touch switches with a pressure of 30 N max.
• Do not press the touch switches when the backlight is not lit or when there is
no display.
• Check system safety before pressing the touch switches.
• Inputs may not be recognized if the touch switches are pressed in rapid suc-
cession. Check that one input operation has finished before performing the
next one.
• A touch position detection error of up to 10 pixels may occur due to the pre-
cision of the NS15-TX01 @ -V2 touch panel. Always take this into account
when positioning functional objects on the panel so adjoining objects will not
be activated by mistake.
• If you touch a point on the panel away from any object and then slide your
finger on the panel until it rests on a functional object on the NS15-TX01 @ -
V2, that functional object will not be activated. You must remove your finger
completely from the panel and then touch the functional object directly to ac-
tivate that object.
• Pressing Three Switches Simultaneously
When the positions of multiple touch switches are set as shown in the example and
three switches are pressed simultaneously, the touch switches will malfunction due to
structural characteristics.
Position the touch switches carefully. In the example shown below, switches have been
created in positions A and B, and at points C and D, where the vertical and horizontal
lines through A and B intersect.

Resolution
NS15: 1,024 × 1,024
The NS15 has no minimum switch size
because the touch panel is analog.
• If touch switches A, B, and C are turned ON
simultaneously, switch D may also turn ON due
to the structure of the touch panel.
• In the same way, if touch switches A, B, and D
are turned ON simultaneously, switch C may
also turn ON.
