4.6. Map Descriptor Example 2 – Bit Storage
This example defines storage location for Relay Point events. The example would work for all other 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.
