BACnet Object Identifier decoder

Free browser tool · nothing is uploaded · updated 18 September 2026

A BACnet Object Identifier packs an object type and an instance number into a single 32-bit value — the top 10 bits are the type, the bottom 22 bits are the instance. This tool goes both ways: pick a type and instance to get the encoded number, or paste a raw Object Identifier to see what it means. Background: what is a BACnet points list? and BACnet object types explained.
