416 Display and Operator Interface Blocks
Range Limiting
To limit the range of values that the operator can enter for the user
variable, select Range Limit Input and enter the desired values for the
smallest and largest allowed values in the appropriate data entry boxes. If
the operator enters a value outside these limits, the value is prompted for
again.
Tag Explorer
User Variables is pre-selected, by default.
Tag Window
Select the user variable whose value is to be edited during runtime.
Note: If a user variable does not appear, right click in the List window
and select New to create a new user variable.
Toggle Choice
Use the Toggle Choice block to create custom menus and prompt the
operator to make a runtime selection from a scrolling list of choices, in a
manner similar to the motion controller’s built-in setup menus for an
operator interface. The toggle choice menus are displayed on the
operator interface port selected in the Interface page of the Configure
Control Options dialog box.
The Toggle Choice block resides on the RS-232/422 Palette.
