6-3-4 Lit (Flashing) and Unlit Touch Switch Statuses

(Changing the Status of Allocated Bits)

This section describes how to change the statuses of allocated bits and thereby the statuses of the touch switches displayed by the NT600S.

The statuses of touch switches displayed by the NT600S are changed by switch- ing the control bits allocated in the PC memory ON and OFF.

NT600S

Lit

Touch switch 1

PC

Allocated bit (touch switch #1)

1 1 (ON)

The status of the control bit reflects the touch switch status, as follows:

0 (OFF): Unlit

1 (ON): Lit (inverse display) or flashing

Procedure 1. Use the support tool to allocate the touch switch control bits to the PC memory.

2.When creating the screen data using the support tool, register the touch switch for a screen.

3.Create the PC program to switch the control bit of the touch switch ON and OFF.

Reference Set whether a touch switch will be continuously lit or blink when its bit has been turned ON by setting the support tool touch switch display attributes.

6-3-5 Notifying the PC that a Switch has been Pressed (Determining Touch Switch Status)

This section describes how the status of a touch switch (whether it has been pressed or not) is ascertained.

With the NT600S, when a touch switch is pressed, the notify bit allocated to that touch switch in the PC memory is automatically notified.
