Basic Control Operation
Chapter 2
2-15
The 9/Series control offers a software MTB panel that performs many of
the functions of an MTB panel. This feature uses softkeys instead of the
normal switches and buttons of a panel. If the control uses a standard
MTB panel (described on page 2-12), or some other custom panel, the
requests for operations from the panel takes priority. This means that
requests of the software MTB panel are ignored if another request is sent
from a standard or custom MTB panel.
The software MTB panel’s operation depends on PAL, especially if the
control uses either the standard or a custom MTB panel. Refer to
documentation prepared by your system installer for details on using the
software MTB panel. Your system installer uses PAL to disable the
{FRONT PANEL} softkey.
Important: By using the PAL flags $SWF1 and $SWF2, you can enable
and disable features available on the software front panel.
Refer to your PAL reference manual for additional information.
