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 map 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.
