15 Control Selectors
Publication 2711E-820 – January 1998
The Control List Selector with 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 sends a new value to the tag, the Control List
Selector’s highlight bar moves to the list state that has this value
assigned. If the state value doesn’t match the tag value, the highlight
bar will be removed. An error state also occurs if the Selector
Control is not assigned. In this case also, no highlight bar appears.
If the Selector Control cannot accommodate a state value, an error
message is displayed, and the PLC value is not changed. The
operator must clear the fault before continuing.
Important: In Remote I/O applications, the PanelView terminal can
retain the current value for the Control List Selector
with Enter Key, even after the terminal is turned off.
Depending on how the Application Startup operation is
defined, the retained value (last state) or initial value
(default) is sent to the PLC when power is re-applied.
For details on configuring Application Startup
operation, see “Application Startup” in Chapter 5 in the
PanelView 1000e, 1200e, and 1400e Operator
Terminals User Manual.
Configuring a Control List Selector with Enter Key
Configure the Control List Selector with Enter Key according to this
table:
Field Meaning
Name Assign a name, up to 15 characters, to document the object for
printed reports. This increases the application’s size by 1 byte
per character.
Control List Type Specify Control List Selector with Enter Key.
Initial State Specify the state that the cursor defaults to when the
application is run for the first time. Choose any of the states in
the list.
Instead of assigning a state, you can enter a blank value in the
Initial State field. This means that the object will always use the
Selector Control’s initial value to set the initial state.
Edit States Change the values of the states. You can assign any unique
value from –2,147,483,648 to 2,147,483,647. For more
information, see “Configuring List Object States,” in Chapter 9,
Creating Objects, in the PanelBuilder 1400e Configuration
Software for Windows User Manual.
Note: To minimize the size of the application file, use state
values that increment by one for each state. Do not configure
more states than you need.
