Display and Operator Interface Blocks
Display and Operator Interface blocks control the display and entering of
information using an operator interface device connected to serial port B
of the motion controller. Some of these blocks can also be used to
interface to the GML Commander Terminal window on the host
computer, using serial port A. When you select DH-485 Link in the
General page of the Configure Control Options dialog box, serial port B
on the motion controller is used for DH-485 communication and the
normal built-in operator interface functions of GML Commander and the
motion controllers are unavailable.
The following table presents the icons for each block in this category
along with a brief description. More detailed descriptions of the blocks
are contained on the pages following this table.
Use this block: To:
Display messages and variable values on the operator interface
Create custom menus that let the operator change user variable
values at runtime, in a manner similar to the motion controller’s
built-in operator interface setup menus.
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.
Perform a controlled interrupt of a current task’s ongoing editing
session, and let another task take over control of the operator
interface for a brief time.
