Cursor Point Operation after Screen Change
1. When a screen is reselected, the Set Bit Cursor Point object that
was last active is active again.
2. The object’s control value is set to 1.
3. All other Set Bit Cursor Point objects in the screen have their
control values reset to 0.
Cursor Point Operation on Terminal Power-up
The Set Bit Cursor Point operation status (Selected or Cancelled) is
always saved. On power-up, as well as when you switch to a new
screen, the Set Bit Cursor Point object that was active when the
screen was last displayed is active.
!
ATTENTION: The Set Bit Cursor Point object should
not share tags with objects used for control purposes.
Sharing tags could cause control functions to start
without the operator’s knowledge.
The following example shows how the PanelView terminal
determines which Set Bit Cursor Point is active.
Example 2: When a Screen Uses Multiple Set Bit Cursor Points
The Application Startup 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 Set Bit Cursor
Points in each row are aligned in columns.
When the application is downloaded, the Set Bit Cursor Point at the top left
corner of the screen is selected as the default and its control is set to 1. If the
right arrow key is pressed, its control is set to 0 and the second Set Bit
Cursor Point in the same row is set to 1.
