4.5. Map Descriptor Example: Read Data
The CMD_DI Map Descriptor polls HCS-R Node_A (described in Client Side Node Descriptors sections) every 5 seconds.
The other Map Descriptors are used to store the data for various loops. Refer to Appendix A for data storage format.

Name one of
the Data Array
defined in
Data_Array
section to store
data
Starting offset
in Data Array
to hold data
One of the
Nodes declared
in Client Node
Section. This
Node will be
polled if
Function is
RDBC
How often (in
seconds) to poll
target device.
Irrelevant if
Function is
Passive_Client
Maximum
number of
placeholders for
data storage.
RDBC will cause
read poll and
Passive_Client is
used to store data
returned by
response.
