6.3.4 Map Descriptor Example.

, DA_AI3 , 0 , Wrbc , Node_A , 100 , 5.0s , 0.0.0.1 , 1 , %R
Only a Wrbc can be used
to produce data. The
other write functions are
not periodic.
The consumer must
be configured to
have the same
producerID and
exchangeID. These
two fields are the
only way it has of
differentiating one
set of produced
data from another. Defines how data is packed
into the data part of the
message.
In this example data will be
packed words (unsigned 16
bit integers) suitable for
storage in register memory
in the GE PLC's.
Appendix C.1 contains a full
list.
Consider this as the
producer interval.
