Configuring Cursor List State Values
To configure the Cursor List State Values, choose Edit States in the
Configure Cursor List dialog box. Configure the Cursor List State
Values according to the following table.
Column Meaning
State Value Assign a value to each state the Cursor List will use. Also assign
values to skipped states. To assign different values to the states,
choose Edit 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.
Skip State Specify whether this state will be skipped. If you choose Yes, neither
the PLC nor the operator can select it. When the operator scrolls
through the Cursor List, the cursor will skip the state.
If the Cursor List is under PLC control, and the PLC sends a state
value for a skipped state to the terminal, the terminal treats the value
as invalid and removes the arrow cursor and highlight. The terminal
will not send a value to the Cursor Indicator control. However, if the
state is a visible state, the state’s value will still be written to the
Visible State control. See “Configuring Skipped States,” earlier in this
chapter, for more information.
Note: If you choose Yes to assign skipped states, the application
will be compatible only with PanelView Firmware Version 2 or later.
The application will not be compatible with earlier versions.
The state values you assign determine how the Cursor List object
operates at runtime, that is, whether the PLC or the Cursor List has
primary control over the Object List values.
•
If the PLC has main control over the Object List values, the
Cursor List object lets the operator use a set of control values
stored in your PLC ladder logic.
To have the Cursor List operate this way, assign consecutive state
values in ascending order, starting from 1 for State 0. Also assign
the Top Position and Cursor Indicator controls. These controls
inform the PLC of the top-most visible state displayed and the
state the cursor is pointing to. The PLC can then determine the
values to be sent to the Object Lists.
Assign the Enable PLC Control, Cursor Control, Enter Key
Control, and Enter Key Handshake control as needed. With this
configuration, the Cursor List’s Visible State controls are not
needed and can be left unassigned.
See the keypad demonstration file provided with PanelBuilder
1400e for an example of a Cursor List that is configured this way.
If you followed the default installation, the file is in the
\AB\PB1400E\DEMO directory. The Scroll List screen contains a
Cursor List grouped with several Object Lists.
