Using a 9/Series Dual--processing System

Editing a Part Program
An “E” next to the program name on the part program directory screen
indicates that the program is currently being edited. Only one program can
be open for editing at a time. You cannot edit programs in more than one
process at the same time.
You cannot edit a program that is currently active (selected to run) in a
different process. If you select process 2 and attempt to edit the active
program in process 1, the control displays an error.
If the same program is active in both processes, you cannot edit the
program unless you deactivate it in one of the processes.
QuickView prompts are available when you write your program (see page
5-17). These prompts help you by describing (often graphically) the
programming of different operations on the 9/Series control. QuickView is
available only to one process at a time. QuickView cannot be activated if
either process currently has either QuickCheck Graphics or Active
Program Graphics turned on.
QuickView does not necessarily prompt you for the currently active
process selected on the control. Independent QuickView process-select
softkeys let you select a process for programming. Changing the process
with this key only changes the axes names and displays to the newly
selected process for QuickView’s prompting. It does not change the actual
currently active process on the control.
When you have a dual-process mill, additional softkeys on QuickView
softkey level 4 are available. These softkeys are named after each of the
process names. The currently selected process for QuickView prompts
has its softkey shown in reverse video. You must still select a plane for
each process for the QuickView feature as described in chapter 5.
Graphics
Active graphics or QuickCheck graphics can be active in only one process
at a time. You cannot switch from graphic to graphic without disabling
graphics in one process and then moving into the other process. You can
use QuickCheck as a program “syntax only” checker (no graphics) in both
processes at the same time.
When you plot the path of a shared axis on a graphics screen the modality
of the process running graphics determines the line type being plotted
(rapid or cutting move). For example if the X axis is shared and is
performing a rapid move in process two, and graphics is running in process
1, process one’s current mode determines if the graphics display shows a
dashed rapid or a solid cutting line. The actual axis speed is not affected
by the graphics plot line type.
