5.4.4 Map Descriptor Example.

In this example the FieldServer can respond to polls the request %R data provided that the request is in the range of address indicated below.

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

Server-R-Data , TABLE_R , 0 , passive, PLC1 , 1 , 1000 ,%R

If the client is

reading then

response data will

be obtained from

this table. If the

client array writing

then incoming data

will be stored in this

array.

Address 1

corresponds to

offset zero (1

st

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 poll that

read and write to

addresses 1 to 1000.

If a poll attempts to

read data at address

1001 then if no

other ma

p descriptor

covers that address

space then a no data

response will be

sent.

This map descriptor

will be used to

process client

read/writes of

Register (%R) data.
