Touch switches can be made to light or flash in accordance with the status of a
host bit in the same way as lamps.
The following 8 types of display graphic can be used for touch switches: Stan-
dard, shadow, 3-dimension, no display frame, rectangle, circle, polygon, sector
When rectangle, circle, polygon, or sector is selected as the shape, the area
within which pressing of the touch switch is sensed (the touch switch area) can
be set independently of the position where the display graphic is set.

Function executed
There are four touch-switch labels: fixed display character strings, ON/OFF
switching character strings, numeral displays, and character string displays.
When fixed display character strings or ON/OFF switching character strings are
used, several lines of labels can be displayed.
Numeric values stored in the numeral memory tables are displayed. The dis-
played numerals can be changed by changing the data stored in the numeral
memory tables.
Hexadecimal values can also be displayed.
When decimal values are displayed, the number of digits for the integral part and
fractional part of displayed values can be specified in advance.
Character strings stored in the character string memory tables are displayed.
The displayed character strings can be changed by changing the data stored in
the character string memory tables.
Numeric values can be input at the PT by using touch switches. The input nu-
meric values can also be stored in a numeral memory table and notified to the
host.
Numeral inputs can be enabled and disabled from the host when an interlock bit
has been allocated.
