1. Product informationThis protocol contains descriptions of all BACnet Object Instances in the EXcon Master. Values in the individual OIs depend on the air handling unit's configuration. For example, the water heating coil return temperature Analogue Input Object Instance 26 will be able to be read regardless of whether a water heating coil is installed in the actual air handling unit or not. But the value will only be useful if an associated temperature sensor is installed.

The BACnet function provides the option for BACnet control and monitoring of a complete Air Handling Unit (AHU), which is equipped with an EXcon Master control system.BACnet functionality is implemented in EXcon Master using software 2.00 or newer.

EXcon Master is a BACnet Application Specific Controller (B-ASC) with supported data link layer options: BACnet IP. In addition, refer to document "OJ-Air2 EDE" (Engineering Data Exchange). See EXHAUSTO’s website (WWW).

Communication TCP/IP: 1 x 10/100 Mbit Ethernet, RJ45 connector

EXcon Master, viewed from above

Object_Identifier Object_Identifier is set automatically to the last 5 digits in the EXcon Master IP address.

Example:IP-address = 172.21.0.95 = 172.021.000.095 - Object_Identifier = 95

NB: Object_Identifier is only set once when the EXcon Master is switched on/restarted.A maximum of 300 values in the COV (Change of Value) can be read at the same time.

BACnet Interoperability Building Blocks Supported

1 x RJ12 for hand-heldterminal
