5.3.3. Map Descriptor Example.
The following Map Descriptors will Serve 256 indication statuses emulating Server Node_A (described in Client Side Node
Descriptors sections). One such Map Descriptor is required for each Node.

Name of one of the Data Arrays defined in the Data_Array section. Indications statuses will be served to clients from this Data Array.
One of the Nodes declared in the Node Section. The Node holds the Node_Id

Specify what type of requests from client should be processed
Number of indication statuses Node will have. It also depends upon Data_Type. All example lengths have the same meaning. Flag - 1 bit, Byte - 8 bits Register - 16 bits 32-Bit_Reg - 32 bits
