17 Control Selectors
Publication 2711E-820 – January 1998
Unlike the Control List Selector with Enter Key, the selections in the
Control List Selector without Enter Key list are highlighted and sent
to the PLC as the operator moves the cursor to each item.
The number of items in this list is determined by the size of the list
component. For information on changing the size of the list
component, see Chapter 9, Creating Objects, in the PanelBuilder
1400e Configuration Software for Windows User Manual.
The Control List Selector without Enter Key consists of these
components:
This component Does this
Selector List This vertical list can have up to 24 different states (each list
item represents a state). With Double High or Large Font,
the list can contain 12 states. If you use the Extra Large
Font, the list can contain only 6 states.
Up Cursor Button When the operator presses the Up Cursor button, the
arrow in the list moves up by one list entry. If the Down
Cursor button is enabled, you can disable the Up Cursor
button. Only one of the Up and Down Cursor buttons
needs to be enabled.
The Up Cursor button auto-repeats at the rate specified in
the Timing Parameters tab of the Terminal Setup dialog
box.
Down Cursor Button When the operator presses the Down Cursor button, the
arrow in the list moves down by one list entry. If the Up
Cursor button is enabled, you can disable the Down
Cursor button. Only one of the Up and Down Cursor
buttons needs to be enabled.
The Down Cursor button auto-repeats at the rate specified
in the Timing Parameters tab of the Terminal Setup dialog
box.
Tip: Build a simple two-position Control List Selector and include
only the Down Cursor button. Functionally, the result is the same as
a Maintained Push Button or a hard-wired, two-position selector
switch. However, you also have a two-position list with the current
selection highlighted.
Note: The Control List Selector without Enter Key recognizes when
the Selector Control value is changed externally. For example, if the
tag assigned to the Selector Control is also assigned to another
object, and this object writes a new value in the tag, the Control List
Selector indicates the new value. If the Selector Control value does
not match any of the list’s state values, the highlight bar is removed.
If the Selector Control cannot accommodate the state value, an error
message is displayed, and the PLC value is not changed. The
operator must clear the fault before continuing.
