Targeted at developers and testers of BACnet devices, the Guide to the Network Port Object discusses the differences between hierarchical and non-hierarchical Network Port objects and the benefits of each. It dives into the changes to the Network Port object when Standard 135-2020, Addendum cc (Protocol_Revision 24) was published and the consequences of choosing between pre- and post-Addendum cc Network Port objects.
This guide provides a detailed list of the required properties and properties that are required to be writable for each data link and what level each required property exists within a hierarchical chain of Network Port objects.
