A popup screen with up to two layers can be displayed. If a popup
screen is displayed, only the screen displayed last will be active. This
means that the background screen terminates and buttons and the like
will not respond when touched.
Data Change Report Function
The controls that provide a function for changing numeral and
character string data are as follows. In the following explanation, these
controls are referred to as controls with a change function. Touching
such a control to enter the data change input state is described as
bringing the control into focus.
a. Numeral indication control with key input
b. Numeral indication control for calling a ten-key pad
c. PMC area character string indication control
The data change report function is a function that, if any of these
controls is used, notifies the PMC that data has been changed with the
change function provided by that control.
A unique identification number is allocated to each control with a
change function, so that the PMC can decide what data has been
changed. As the identification number of each control, a value in the
range of 0 to 4095 can be set in “Identification number,” found in the
action property page of that control. An identification number of 0
may be set for more than one control, and means that “no data change
will be reported to the PMC.” An identification number 1 to 4095 can
be allocated to a control that is to report a data change. Within a
project, each identification number must be unique. In the following
explanation, a control with a change function that has an identification
number of 0 is referred to as a change non-report control, while that
that has an identification number other than 0 is referred to as a
change report control.
The data change report function requires that a 2-byte continuous area,
with the structure shown below, be reserved on the PMC. Different
change report areas can be specified for different base screens. The
2-byte change report area will be cleared to zero when the
corresponding base screen is displayed.
