The Data_Array_Offset sets the start of the data range covered by the Server Map Descriptor. The number of points included is determined by the Length field.
The Server function tells the FieldServer that this Map Descriptor makes data available to a Client sending polls to the FieldServer.
Note that a single Server Map Descriptor of length 256 can represent all possible points of one type (e.g. AI).
