5.3.4.Map Descriptor Example.

Map_Descriptor_Name,	Data_Array_Name,	Data_Array_Offset,	Function,	Node_Name,	Address,	Length,	Data_Type
Server-R-Data,	TABLE_R,	0,	Passive,	PLC-1,	1,	1000,	%R

If the Client is reading then response data will be obtained from this table. If the Client is writing, incoming data will be stored in this array

Address1 corresponds to offset 0 (1st location) in the array. If Client reads %R15 then driver responds with data from element 14 of the array.

This is a Server. It responds to polls but does no active work itself.

This Map Descriptor can be used to respond to a poll that reads and writes to addresses 1 to 1000. If a poll attempts to read data at address 1001, then if no other Map Descriptor covers that address space, a “no datas” response will be sent.

This Map Descriptor will be used to process Client read/writes of Register (%R) data.
