Cursor Point Function on Power-up
On power-up the Set Bit Cursor Point operation status, Selected or
Cancelled, is retained. The active Set Bit Cursor Point object is the one
active when the screen was last displayed.
IMPORTANT: Immediately after the downloading or the loading of a
new file from user PROMs, the operation status is selected.
ATTENTION: The Set Bit Cursor Point object should not
share addresses with objects used for control purposes. For
example, if a Set Bit Cursor Point on screen 2 is assigned to the
same address as a Normally Closed Push Button on screen 1, the
Normally Closed Push Button will open when screen 2 is
entered if the cursor point is not selected as the active point as
described earlier.
Examples: Set Bit Cursor Point Operation
1. In this example, a screen has five set bit cursor points; three in a row
at the top of the screen, and two in a row below. The first two cursor
points in each row are aligned in columns. Each cursor point uses a
unique bit address that is not shared with any other objects in the
application.
When the application is downloaded, the cursor point at the top left
corner of the screen is selected as the default and its PLC input
address is set to one. If the right arrow key is pressed, its PLC bit
address will be set to zero and the second cursor point in the same
row will be set to one.
2. In another example, the screen also has five set bit cursor points;
three in a row at the top of the screen, and two in a row below. The
last cursor point in the second row, however, uses the same address as
a set value button with a preset value of 1. In addition, the second
cursor point in the first row shares the same address with another set
value button, which is also preset to 1.
