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 2ndary storage can be used to determine if more than one event is active at a time.

MD’s 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.
