Map_Descriptor_Name, Data_Array_Name, Data_Array_Offset, Data_Type, Function, Node_name, Address, Length

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).

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.
