ClearAll
Since an Xpoint message only reports when a c-p-s goes into a non-normal state, this function is provided as a means of synchronising FieldServer to the panel
when everything is normal. The function is typically used in conjunction with pseudo-point(s) programmed into the panel. The underlying logic assumes that
the affected point(s) trigger the driver to clear sections of one or more Data Arrays when they report a state of U1
If an Xpoint message is received from the Panel for the specified c-p-s with the ClearAll function (or clist is used to poll for the state of the c-p-s) and the state
is U1, this triggers this ClearAll action. The driver sets all array points covered by all Map Descriptor's with the clearall function to zero, without consideration
of the c-p-s associated with the Map Descriptor.

Two different arrays, starting at two
different locations and with two
different lengths will get set to zero
when c-p-s=1-2-3 goes to state U1.

Read Poi nt Status
This Map Descriptor can be used to poll for the status of a particular point. When the response is obtained the driver sets the value of one Data Array element
to a number indicating the point's status. The values are described in . One Map Descriptor is required for every point polled.

An Xpoint Map Descriptor must be
created for any clear all c-p-s. The clear
all logic never gets called until an Xpoint
store is done for the c-p-s configured to
do ClearAll.
