5.5 Map Descriptor Example 2 – Bit Storage
This example defines storage location for Relay Point events. The example would work for all point types. In the example, both primary and secondary storage
Data Arrays have been specified. The driver stores index values in the primary array. Each new event for a particular relay will overwrite the value stored
previously. In the Bit Array, the driver sets the bit corresponding to the event, leaving other bits unchanged – thus the Secondary storage can be used to
determine if more than one event is active at a time.

Map Descriptors for
storing Relay, Loop, Zone
and Panel do not need the
address specified. Data_Array_Name is where the primary DA is specified. Index values are stored
here.
DA_Bit_Name is where secondary storage is defined. Events are stored by
setting appropriate bits.
Remember that 2 elements per Relay, Module, Sensor, Loop are used.
