Available Restart Modes for the ACX 57xx Series Controller
The ACX 57xx series controller reset mode is not configurable.
On startup, the ACX controller will first attempt a warm start. If it is
unable to perform a warm start, it will attempt a cool start, and finally
will perform a cold start if it can not perform a cool start.
Warm to Cool The controller powers up from a loss of power with the user
(Power Loss configuration in place. The user configuration is that which was
Restart present in the controller and preserved due to battery-backed memory
Attempt) when the power was lost. Point log data is preserved. Plain English
programs are restarted at the same logical line that was being
interpreted when the controller shut down. All user points have their
values restored.
Cool Start In this mode, the user database is backed-up to the User Backup Area
of Flash memory upon user command only (manually). When the
controller powers up after a reset, it examines the backup area in Flash
memory, and if a valid backup is found, the data is restored to RAM.
Certain portions of the data are re-initialized:
z
Point values whose SetPoint attribute are TRUE have their values
restored.
z
Input point values are purged and a fresh sample obtained from the
hardware before the Scanner runs.
z
Output points are purged.
z
All automatic log data are purged.
z
Manual array data are retained at the value when the last flash
backup was accomplished for setpoint variables only.
z
The CurrentLine attribute of Plain English programs is set to its
first line. The program is run ONLY if the AutoStart attribute is
TRUE. The State attribute is restored and its value observed.
z
Doors are restored but any run time attributes (such as
EntryLastCard, EntryLastSite, and so on) are reset to their default
values.
