BACnet¶
The smartdirector facilitates two-way communication between the smartengine installation and external building management system (BMS) applications. To enable BACnet service, you need to configure BACnet parameters on the smartdirector.
Enabling BACnet service
- Navigate to the Commission System application in smartmanager and select the BACnet tab under the System Settings section.
- You must configure a unique device identifier for the smartdirector. This is the identifier used to other BACnet systems to communicate with the smartdirector.
- BACnet uses TCP port 47808 by default. You can configure the system to use a different port if that is what your BACnet systems are using.
- There are few optional settings that identify the sensor data and other controls with custom names. Consult your BACnet systems administrators to see if it is required to be set.
- Once the parameters are configured, you may restart the service by enabling it through the smartmanager.
After enabling the BACnet service on smartdirector, you may communicate with it through your BACnet building management system by doing the following:
- On your BMS, add the smartdirector to the BACnet network by locating it by its device ID. You can use device discovery to locate it.
- Add smartengine system objects using BMS object discovery.
You may take advantage of BACnet protocols change of value support in smartdirector to monitor changes to the object values.
Warning
The smartdirector and BACnet devices are expected to be in same IP subnetwork, unless the subnets already have a BACnet Broadcast Management Device (BBMD). If the IP networks are different, please make sure you have BACnet routers (BBMDs) and infrastructure available and configured for the BACnet communication to work over multiple networks.
Supported Objects (set points)¶
The smartdirector supports a number of different objects. Some of these are unique to each location and others are unique to each fixture (sensor).
