(3)Positional precision
A positional precision of "2.5 mm can be maintained by performing
9–point compensation as described later.
When a rectangular soft key button on the screen is pressed, the soft key
button display is indented. This type of a soft key behaves in the same
manner as conventional soft keys. In addition, the touch panel soft keys
can be customized using the C executor.
When the cursor is displayed, pressing the desired point on the screen
causes the cursor to move to that point, in the same way as with the
,
, , and cursor keys.
Touch panel–based application programs can be created using the C
executor.
Refer to the C Executor Programming Manual (B–62443EN–3) for
details of the C executor.
(1)Functions
Calibration functions as follows:
1) Specifies an effective input area.
2) Specifies maximum coordinates.
3) Corrects linearly.
4) Makes the panel input position match the LCD display position.
(2)Execution time
Calibration must be executed when:
1) A new touch panel is installed.
2) An existing touch panel is replaced.
3) Memory (SRAM) is cleared to all 0s.
(3)Cautions
1) If an alarm condition occurs during calibration, the alarm screen
appears when the calibration screen is exited.
2) Calibration can be made regardless of what the current mode is.
3) Once the system gets started, calibration should be made promptly
before actual operations begin.
(4)Procedure
1 Enable touch panel calibration by setting parameter DCL (bit 5 of
parameter No. 3113) to 1.
2 Press the
SYSTEM
function key.
3 Press the rightmost soft key,
