Cursor Control Address is an output address from the PLC that
informs the terminal where to position the cursor in the Scrolling List.
The address contains the value of the state to place the cursor on.
For example, if the PLC places a value of 100 in the Cursor Control
address, the PanelView terminal will place the cursor on the 100th state
of the list. Based on the Number of Visible States and Preview States
configured, the PanelView will scroll the visible states accordingly, and
send the appropriate value to the top position address. The PLC will
then use the Top Position Address value to place the appropriate top or
first visible state value and consecutive values in the visible state
addresses. The following figure illustrates how this works.

If the PLC sets the Cursor Control Address value to 0, the cursor list
buttons control the cursor. Until a Cursor List button is pressed, the
cursor will remain on the last state according to the last value that was
placed in the address.
The Cursor Control Address is an Output only address. You can
configure the data type to Binary, BCD or Bit.
Cursor Indicator Address informs the PLC of the cursor’s location in
the Scrolling List. The address contains the value of the state that the
cursor is pointing to. The terminal updates this value when the cursor
position changes.
This address value is updated regardless of the value in the Cursor
Control Address. If the Cursor Control Address value is 0, the Cursor
List buttons control the Cursor Indicator Address value. If the Cursor
Control Address value is not 0, the Cursor Indicator Address value
reflects the Cursor Control Address value.
This is an Input only address. You can configure the data type to Binary,
BCD or Bit.
