CI-ControlWave Express Installation & Operation / 2-41
Automatic Mode
In Automatic mode a set of screens (based on the application) are displayed. The
application programmer provides strings for the opening screen. From there the firmware is
responsible for displaying the screens and responding to key presses. Screens are fixed and
start off with an opening screen, which displays user information passed into the function
block. Users can view a list to select which list is to be scrolled. Once the list to be scrolled
has been selected, the user can scroll through the list by pressing the down arrow key. List
elements will be displayed automatically, scrolling at a predetermined rate (determined by
iiScrollTime). The user may pause on a variable by pressing the right arrow key. Pressing
the right arrow key again will cause the list to start scrolling again.
The essence of Automatic mode is that the user can supply inputs into the function that will
determine which list can be displayed, but cannot change the menu or display. The user is
allowed to select a list and to start/stop scrolling.
Manual Mode
In Manual Mode the programmer is responsible for creating each screen and displaying the
next desired screen, based on key inputs. The programmer has access to all lines of the
display and can provide any string that he/she desires to display. Special formats that must
be adhered to that allow the programmer to display what they want on the screen are
provided in the description of iaScrnSruct
in the Display function block within ControlWave
Designer’s On-Line Help. It should be noted that currently, Manual Mode does not support
reading Keypad keypresses. Note: Manual Mode operation requires ControlWave
Firmware 4.50 or newer.
