IMPORTANT: The Cursor Indicator Address should not share its address
with other objects. Overlapping objects may cause unpredictable results.
Top Position Address informs the PLC of the value of the state
displayed at the top of each Object List.
This value directs the PLC to what value should be placed in the first or
“Top” Visible State address.
This is an Input only address. You can configure the data type to Binary,
BCD or Bit.
IMPORTANT: The Top Position Address should not share its address
with other objects. Overlapping objects may cause the PLC to display a
wrong range of numbers.
Enter Key Control Address indicates when the Cursor List Enter
button is pressed.
This is an Input only address. The Bit and size is 1.
See the following button operation section for value and timing
characteristics of this address and button.
Enter Key Handshake informs the terminal that the PLC has read the
Enter Key Control Address.
This is an Input/Output address.
See the following button operation section for value and timing
characteristics of this address and button.
Object List
An Object List is a list of objects of the same type. These objects are
displayed in accordance with the Cursor List.
The Object List(s) and the Cursor List together make up the Scrolling List.
You must define the Cursor List before you can create an Object List. You
can create any number of Object Lists for each screen, as long as there is
sufficient space on the screen.
Although you define the Cursor List and Object List components
separately, they are in fact components of a single Scrolling List object.
Therefore the Cursor List’s definition—Cursor Control address, Cursor
Indicator address, Top Position address, Number of States—also applies to
all the Object List(s) in the Scrolling List.
