7 +Each job with Cresnet devices will have at least one Cresnet bus network. Every Cresnet bus network has a single //host// or //primary// device and one or more //client// or //secondary// devices (older materials may refer to hosts as //masters// and clients as //slaves//). Every Cresnset device on a given Cresnet bus must be assigned a unique, two-byte hexadecimal Cresnet address, and the amount of available addresses is determined by the bus host. In addition
