Support Connection Path Type
Logical encoding is used for the Polled Consumed and Produced connection paths. To support application tools and
development tools that do not handle explicit message fragmentation this option supports Symbolic encoding. Symbolic
encoding only requires a 3 byte long message where logical encoding requires eleven bytes. This option has a third
method of setting Polled Consumed and Produced connection paths. Class 5, Instance 2, Attributes (100, 101) allow
setting connection path with a single byte. For instance, to set the Consumed connection path to 100, write 100 (0x64) to
Attribute 101. See appendix C of "The CIP Networks Library, Volume 1" for more information on CIP segments.
