Using a 9/Series Dual--processing System
30-3
You cannot switch the active process while you use the digitize feature, a
tool path or QuickCheck graphic display, or within an active program
search operation. If you attempt to switch the active process while using
one of these features, the control displays an error message. Select an
active process by using one of these methods:
Method:
Description:
[PROC SELECT] key
found on the operator panel next to the [TRANSMIT] key.
Each time you press the [PROC SELECT] key, the currently
active process changes as shown on the CRT.
System installer’s key
your system installer can control which process is active at a
given time through PAL. Refer to your system installer’s
documentation for details on the location and operation of this
feature.
[SHIFT] key & {
• } softkey on
the end of the softkey rack
you can toggle between processes each time you press these
keys. This functions identically to the [PROC SELECT] key.
All functions performed on the operator panel (this includes softkey
functions), and position displays (except for split-screens) are
representative of the currently active process. On split-screens, the CRT
display shows position displays and process information for both
processes.
Split-Screen Displays
All of the 9/Series position display screens are available as split-screens.
A split-screen is a screen that shows both processes at the same time on the
CRT, regardless of which process is active. Refer to page 8-21 for details
on using the split-screen feature.
The Part Program Directory
Both processes share the system’s part program directory. They both have
access to the same programs. They can be activated from both processes.
The system directory shows which process has programs active or being
edited at any given time. An “A1” or “A2” next to the program name
shows which process currently has the program active. An “A12” next to
the program name shows the program is currently active in both process 1
and process 2.
If you execute a part program from a tape reader, each process must have
its own tape reader. However, you can use one tape reader if you load the
part program into memory for one process.
