Lit (Flashing) and Unlit Touch Switch Statuses
(Changing the Status of Allocated Bits)
Notifying the Host that a Switch has been Pressed
(Determining Touch Switch Status)
Procedure 1. Use the support tool to allocate the touch switch lamp bits to the PC memory.
This section describes how to change the statuses of allocated bits and thereby
the statuses of the touch switches displayed by the NT20S.
The statuses of touch switches displayed by the NT20S are changed by switching
the control bits allocated in the PC memory ON and OFF.
The status of the lamp bit reflects the touch switch status, as follows:
2. When creating the screen data using the support tool, register the touch switch
3. Create the PC program to switch the lamp bit of the touch switch ON and OFF.
This section describes how the status of a touch switch (whether it has been
pressed or not) is ascertained.
With the NT20S, when a touch switch is pressed, the notify bit allocated to that
touch switch in the PC memory is automatically notified.
0 (OFF):
1 (ON):
for a screen.
Set whether the lamp lights continuously or flashes when the bit comes ON by
setting the touch switch display attribute with the support tool.
