FS-8700-41 Simplex 4100 Driver Manual
Appendix A.4.3.
Using unsolicit ed messages f rom the Pa nel to det ermi ne point stat us
This Map Descriptor can be used to store point status data when the FieldServer receives an unsolicited message from the Panel containing point status
information (Xpoint messages). The panel sends an Xpoint message each time a point's status changes to a non-normal state. Using these Map Descriptors
will ensure that the FieldServer is constantly updated with the latest panel status information. The Map Descriptor's are pa ssive so they can be used in a joint
strategy with the clist function (Appendix A.3.1) to keep track of a point's status.
One Xpoint Map Descriptor is required for storage of Xpoint messages from each card. For a given card, the driver uses a mapping function based on the point-
subpoint address to determine the array location to store the state for the c-p-s.

When used with an Xpoint Map Descriptor this parameter
allocates the number of sub-points per point. In this case the
driver uses 10 array locations for each point.
Thus
Point 0: Array locations 0-9
Point 1: Array location 10-19
Point 2: Array locations 20-29 ...
E.g. If the Xpoint message is for 1-1-0 then the state will be
stored at location 10.
If the Xpoint message is for 1-2-5 then the state will be
stored at location 25.
