Touch Switches
Section 7-7
Since the special auxiliary relays of the CVM1/CV series PCs are all allocated to
system functions, they cannot be used for purposes other than system use.
The range of each memory area differs according to the PC type. Refer to AP-
PENDIX L “PC Memory Map”, page 684.
Reference: For touch switches for which the host notification function is set, a bit for host notifi-
cation must be allocated in addition to the lamp bit.
[Display Functions]
As with lamps, it is possible to set a graphic area for a touch switch which is dis-
played in different ways according to the status of a bit at the host. The bit at the
host that is allocated to control the touch switch display is called a “lamp bit”.
The status of the lamp bit has the following effects.
0 (OFF):
Lamp is OFF
1 (ON):
Lamp is ON or flashing
Whether the lamp is ON or flashing when the lamp bit is set to “1” (ON) is deter-
mined by the setting made for the “On Type” property of the touch switch.
When a “lamp bit” is not allocated, touch switch performs only “Show ON State”
function.

When “Show ON State” is set, the display graphic is displayed in reverse video
when the touch switch is pressed.
[Input Functions]
The touch switch elements of the NT31/NT31C 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.

One touch switch can comprise
multiple touch switch elements.
Function Execution
When the touch switch is pressed,
the set function is executed.
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 func-
tion 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.
