Description
The MXL software was written in a
high level language for ease of main-
tenance. The software incorporates a
multitasking operating system that
allows the microprocessor to handle
many tasks almost simultaneously.
This enables the MXL System to
handle communications to all initiating
and output option boards and to the
annunciator. This also enables the
MXL System to check that everything
is running.
When the MXL Control Panel receives
power, the System runs a start-up
procedure that sets up all initial condi-
tions. The System then starts the
operating system and the initialization
routines for all of the tasks, most of
which concern handling System
modules. When the display task is
finished initializing, it displays the
default time and date at powerup.
Initialization of other modules may take
several seconds, but this takes place in
the background and so does not affect
System operation.
The MXL System polls all network
addresses to see that all specified
modules are present and that there are
no unspecified modules. Any modules
or devices that do not agree with the
programmed data are reported as
troubles on the annunciator.
