7.
Virtual Input Modules are numbered immediately after the Virtual Output Modules.
8.
Virtual Input Modules are sorted before being assigned a Device Instance Number. They are
sorted first by its configured name, then by its address, then by an internal UUID to ensure a
consistent sort order.
This Device Instance Numbering scheme ensures that, for a given system configuration,
all Device Objects maintain a consistent numbering.
The Object Instances associated with each Device Object are as shown in the
Object/Property Support Matrix. The Exhaust Fan Device Objects, for example, contain
the Object instances listed under the “For each Exhaust Fan and Auxiliary Airflow”
section. For each Device Object, its Objects will be in the ordered listed. For example,
Operation Status will always be Binary Value 0 for each Exhaust Fan or Auxiliary Airflow.
Device Object MAC Address
The MAC address for each Device Object is based upon the IP address of the Intelli-Hood
3 System Controller. The System Controller Device Object will match the System
Controller IP address and it uses the standard BACnet UDP port 47808 (0xBAC0) by
default. For the rest of the device objects, the IP address is reversed and the last octet is
set to 1 for the first additional Device Object. The last octet is then incremented for each
additional Device Object.
Example Scenarios
Below are some example configurations to show how the Device Object numbering and
the MAC addressing works with the default configuration options.
Scenario 1:
System Controller IP Address: 142.51.5.36
Exhaust Fan 1: KEF-02, Modbus Address 2
Exhaust Fan 2: KEF-05, Modbus Address 5
Auxiliary Airflow 1: MUA-41, Modbus Address 41
Hood Controller 1: HC-01, Hood Network Address 1
Virtual Output Module 1: VOM-01, address 1
