BACnet Basics

What is BACnet?

BACnet (Building Automation and Control Networks) is a communication protocol for Building Automation and Control (BAC) systems. It was developed to allow communication between building automation devices regardless of the manufacturer.

Key Concepts:

  • • Objects: Logical representations of physical or virtual components
  • • Properties: Attributes of objects (Present Value, Status Flags, etc.)
  • • Services: Operations that can be performed (Read, Write, etc.)
  • • Device Instance: Unique identifier for each BACnet device

Object Types

Analog Objects (AI/AO/AV)

Continuous values like temperature, pressure, flow rates

Binary Objects (BI/BO/BV)

On/off states like pumps, fans, alarms

Multistate Objects (MSI/MSO/MSV)

Multiple discrete states like auto/manual/off

Common Issues & Solutions

No Devices Found

If UBACnet can't discover any devices, check the following:

  • • Ensure your iOS device is on the same network as BACnet devices
  • • Check that UDP port 47808 is not blocked by firewall
  • • Verify that broadcast traffic is allowed on your network
  • • Try manual device entry if you know the device IP address

Connection Timeouts

If you're experiencing frequent timeouts:

  • • Check network latency and stability
  • • Verify the device is responding to BACnet requests
  • • Ensure the device instance number is correct
  • • Try reducing the number of concurrent property reads

Write Operations Failing

If you can't write to objects:

  • • Check if the object is writable (not in out-of-service)
  • • Verify you're using the correct priority level
  • • Ensure the value is within acceptable range
  • • Check device-specific write permissions
