10Ć9 AutoMax Processor Overview
2. An application configuration check is performed. If the
application configuration check determines that an I/O module is
missing or not functioning, an error code is displayed.
3. Forced outputs are set to their forced values.
WARNING
VARIABLES AND OUTPUTS WHICH ARE FORCED BEFORE AC POWER IS LOST
WILL REMAIN FORCED WHEN AC POWER IS RESTORED. SHOULD AC POWER
BE LOST WHILE VARIABLES ARE FORCED, THE USER MUST ENSURE THAT
UNEXPECTED MACHINE MOVEMENT DOES NOT OCCUR WHEN AC POWER IS
RESTORED. FAILURE TO OBSERVE THESE PRECAUTIONS COULD RESULT IN
BODILY INJURY.
4. Volatile common variables are cleared, i.e., initialized to 0, false,
or off, if they are not forced. The values of local variables,
nonĆvolatile common variables, and forced volatile common
variables are retained. All I/O points are cleared.
5. The application tasks are built," i.e., the system data structures
are created.
6. The application tasks are installed. The status code d0" is
displayed during the installation because this may take a
significant amount of time, depending on the size and number of
tasks to be installed. The Processor attempts to read all I/O
locations to verify that they are still there.
7. Application tasks may be reĆstarted if the reĆinitialization was the
result of power being turned off and AUTOĆRUN is enabled.
Otherwise, application tasks are not automatically reĆstarted. See
12.4 for more information on AUTOĆRUN.
