• Reverse display on input
It is possible to set a touch switch so that its display will be inverted when it is
pressed.
• Guide display
Labels can be assigned to touch switches. When the touch switch is ON, the
label is displayed in reverse video in the case of an NT620S and in the exclu-
sive XOR color (see page 121) in the case of the NT620C. Attributes of guide
display characters are in the same way as character display. Refer to "Charac-
ter Types and Attributes" (page 134).
• Lit and flashing
This attribute can specify whether or not the Touch Switch is allowed to be ON
or flashing when the Touch Switch is ON or flashing according to an instruction
from the PC.
• Color display (NT620C only)
External frame color (when displayed): 8 colors
OFF color: 8 colors or "transparency"
Lit/Flashing, entry color: 8 colors
The NT620S/620C can switch over the screen only by operating the switches
without instructions from the PC. This function is referred to as "Stand Alone
Function".
When a screen data is created with the support tool, the screen number of a
screen to be switched over is assigned to the input terminal of the touch switch.
When the touch switch is pressed during operation, the screen of the number
specified is displayed. At this time, the screen number just switched over is also
notified to the PC.
Depending on the screen number allocated to it, a touch switch can be made to
perform one of two functions:
- When a screen number in the range 1 to 2000 is specified:
Pressing the touch switches causes the display to switch to the screen with
the specified number.
- When screen number "0" is specified:
The touch switch functions as the screen switchover return key. Setting this
key allows you to return to the screen that was displayed immediately before
the current screen.
