CCN Addressing The Key to the CCN BUS is Addressing: • An address is required of all devices on the bus. • No two devices on the same CCN system may ever have the same address. • A CCN and CCS address consists of a 3 digit bus number and a 3 digit device number. Copyright © Carrier Corp. 2008 11

Addressing Rules CCN BUS is Addressing: Example Address: ( 024 , 127) Device Number Bus Number • Legal bus numbers are 0 to 239 inclusive – The primary bus number is always “ 0” Note: All CCN device come from the factory at bus “ 0” – Secondary bus numbers are 1 to 239 inclusive. • Legal device numbers are 1 to 239 inclusive. • A repeaters are not addressed.

CCN BUS Broadcast Communications Rules * Many CCN devices may broadcast information over the network such as time of day or point values like outdoor air temperature, or relative humidity. * Broadcast information is sent (or made available) to all Network Devices. * Every BUS should have one device configures as a the “Broadcast Acknowledger” * The Broadcast Acknowledger acts as a spokes person for the entire Bus by acknowledging back to the sender that a successful broadcast was received. * Time broadcaster's send their internal clock time and holiday status twice a day at 1: 00 AM and 1: 00 PM, as well as when requested to send time by another Network Device.
