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 (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 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.
