Field Meaning
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.
Up Cursor Specify whether the Up Cursor button is enabled, and, if you
have a keypad application, select a function key. You must
have at least one of the Up and Down Cursor buttons enabled.
Down Cursor Specify whether the Down Cursor button is enabled, and, if you
have a keypad application, select a function key. You must
have at least one of the Up and Down Cursor buttons enabled.
Enter If you have a keypad application, specify which function key the
operator must press to choose the highlighted selection.
Control The Control List Selector with Enter Key uses the following
controls:
Selector Control records the state value of the list item
currently selected. You can assign a tag only to the Selector
Control.
Note: If you do not assign this control, an error state occurs
when the object is displayed on the PanelView terminal. No
highlight bar appears on the list, alerting the operator to the
error state.
Enter Key Control records that the Enter Key has been
pressed. You can only assign a tag to this control.
When Enter is pressed after the Enter Key Control Delay time
has elapsed, the control is set to 1 for the Enter Key
Handshake Time (specified in the Timing Parameters tab of the
Configure Terminal Setup dialog box) or until the Enter Key
Handshake makes a 0 to non-0 transition. When either occurs,
the Enter Key Control is reset to 0.
Since this control uses only two values, a digital tag is
recommended.
Enter Key Handshake is set by the PLC to confirm that it has
recorded the change for the Enter Key Control. You can assign
a tag or expression to the Enter Key Handshake control.
The PanelView terminal sets the Enter Key Control to 1 when
the operator presses the button. PLC logic must set the Enter
Key Handshake to non-0 when the Enter Key Control is set.
When the terminal detects a 0 to non-0 transition in the Enter
Key Handshake, it resets the Enter Key Control to 0. PLC logic
must then reset the Enter Key Handshake to 0.
If this control is left unassigned, the Enter Key Control is reset
after the Push Button Hold Time.
