414 Display and Operator Interface Blocks
Edit Value
Use the Edit Value block to create custom menus that let the operator
change user variable values, in a manner similar to the motion controller’s
built-in operator interface setup menus. These custom menus are
displayed on the operator interface port selected in the Interface page of
the Configure Control Options dialog box.
The Edit Value block resides on the RS-232/422 Palette.
When the Edit Value block executes, it prompts the operator for a new
user variable value. A prompt message appears on the operator interface
(either the GML Commander Terminal Window via Port A, or a separate
operator interface terminal via Port B), followed by the current value of
the selected user variable. The operator then enters a new value and
presses ENTER, which updates the value of the specified user variable.
See the Setup section of the Installation and Setup manual for your
motion controller for more information on configuring the operator
interface.
If other tasks are executing (multitasking), the task that contains this
block pauses while the operator enters the new variable value, but the
other tasks continue to execute. In this way, an Edit Value block in one
task does not pause execution of any other task, or hang the task
dispatcher.
While the operator is entering the new value, mistakes can be corrected
using CLEAR on the integrated Setup and Diagnostic Panel on the IMC-
S/21x controllers, or the Delete or Backspace keys on a terminal.
