Building automation system with smart communications controller for building equipment

A smart communications controller for building equipment, the smart communications controller comprising:

• an equipment port connected to the building equipment, wherein the building equipment operate to affect a variable state or condition within a building;
• and
• a processing circuit comprising a plurality of autoconfiguration objects, each of the autoconfiguration objects corresponding to a different communications protocol and configured to perform a protocol testing process comprising:
• determining whether the corresponding communications protocol supports sending a request for an equipment ID to the building equipment;
• selecting a protocol identification technique based on whether the corresponding communications protocol supports sending the request for the equipment ID to the building equipment;
• and
• using the selected protocol identification technique to automatically determine whether the corresponding communications protocol is used by the building equipment connected to the equipment port;
• the processing circuit comprising an autoconfiguration manager configured to cause the autoconfiguration objects to iteratively perform their protocol testing processes until the communications protocol used by the building equipment is identified;
• the processing circuit comprising an equipment controller configured to use the identified communications protocol for the building equipment to generate protocol-specific control signals for the building equipment and to operate the building equipment to affect the variable state or condition within the building.
