enteliWEB Site Setup and BACnet Network Configuration
Key Takeaway
How to create a site in enteliWEB, configure BACnet/IP network settings, set the device instance range, and prepare for BACnet device discovery.
Quick Answer
A site in enteliWEB represents a BACnet network segment or building. Create a site in the administration panel, configure the BACnet/IP interface (local IP, UDP port 47808, broadcast address), and set the device instance range before running device discovery.
Creating a Site
In enteliWEB administration, click Add Site. Enter the site name, description, location, and timezone. Each site represents a distinct BACnet network or logical grouping of buildings.
BACnet/IP Configuration
- Local IP Address — The server NIC that connects to the BACnet/IP network
- UDP Port — 47808 (standard BACnet/IP port, hex 0xBAC0)
- Broadcast Address — Subnet broadcast for Who-Is discovery
BBMD Configuration
If BACnet devices span multiple IP subnets, configure a BACnet Broadcast Management Device (BBMD) to relay broadcast messages across subnets. Without BBMD or foreign device registration, devices on different subnets will not be discovered.
Foreign Device Registration
If enteliWEB is on a different subnet from the BACnet controllers, register enteliWEB as a foreign device with a BBMD on the controller subnet. This allows enteliWEB to receive broadcast responses from controllers it cannot reach via local broadcast.
Time Synchronization
Configure NTP settings to synchronize the enteliWEB server clock with the building automation controllers. Accurate timestamps are critical for trend logs, alarm history, and schedule execution.
Frequently Asked Questions
BACnet/IP uses UDP port 47808 (hex 0xBAC0). This port must be open on firewalls between enteliWEB and BACnet controllers.
A BACnet Broadcast Management Device allows BACnet broadcast messages to cross IP subnet boundaries. Without BBMD, devices on different subnets cannot discover each other.
