Abstract
A building system includes heating ventilation or air conditioning (HVAC) devices configured for communication on a building automation network and a communication engine. The communication engine is configured to provide a diagnostic attribute. The diagnostic attribute indicates communications with the HVAC devices as being according to a first communication protocol or at least one different communication protocol. Systems and methods may detect insecure communications and/or upgrade in secure communication protocols in wireless or wired networks, such as, BACnet systems and/or subsystems.
