Supported Services; Data-Sharing Services; Device Management Services - Grundfos CIM 300 User Manual

4. Supported services

BACnet Interoperability Building Blocks (BIBBs) are collections of one or more BACnet services. These are described in terms of an "A" and a
"B" device. Both devices are nodes on a BACnet inter-network. In most cases, the "A" device will act as the user of data (client), and the "B"
device will be the provider of this data (server).
CIM/CIU 300 and 500 are BACnet Application-Specific Controllers (B-ASC) with a few additional services.
