Guides

Start here

• What is BACnet?
  BACnet is the standard protocol building controls use to talk over a network: HVAC, lighting, metering.
• BACnet glossary: what do all the terms mean?
  Plain-English definitions of BACnet terms you meet in the field: device, object, point, Present_Value, priority array, Who-Is, BBMD, MS/TP and more.
• What is a BACnet IP points list?
  A BACnet IP points list inventories every object a device exposes: type, instance, name, present value and units.
• Is there a BACnet IP scanner app for Android?
  Yes.
• BACnet vs Modbus — what is the difference?
  BACnet is self-describing with built-in discovery; Modbus is a bare register protocol with neither.

Reading and exporting

• How do I scan for my BACnet points list?
  Step by step: get on the controls network, scan for BACnet IP devices, check their points, and share the whole lot as an Excel report from your phone.
• How do I export a BACnet IP points list to Excel or CSV, and what is an EDE file?
  Scan a building from your phone and export every BACnet IP device and point as an Excel spreadsheet to share or save as CSV.
• How do I read BACnet values from a phone?
  Step by step: join the controls network, discover BACnet IP devices, then open a point and read its live value, units and status on an Android phone.
• How do I find my BACnet IP points list?
  Four ways to get a BACnet IP points list: contractor submittals, a BMS export, a network scan from your phone, or reading Object_List directly.
• A vendor asked for my BACnet information — what do I send them?
  What to hand a vendor or integrator who asks for your BACnet details: device IDs, IPs, a full points list, and how to export it as a spreadsheet.
• How do I test a BACnet IP device without a BMS?
  You don't need the BMS to prove a BACnet IP device works.

When a scan finds nothing

• What do I do if I can't find my BACnet devices?
  A plain-English checklist for when a scan finds nothing, misses a device, shows a device with no points, or a point with no value.
• Why can't I find my BACnet IP devices?
  Why a BACnet IP scan finds nothing, in plain terms: usually the wrong network, or BACnet IP is turned off in the device.
• Why am I on the wrong network even though I'm plugged into the switch?
  A switch port doesn't mean you're on the controls network.
• How do I tell if a BACnet device is online?
  A hands-on test that separates a network problem from a BACnet problem: find the device IP, ping it, then add it by IP, and what each result means.
• Why does my BACnet IP device show offline?
  A BACnet IP device showing offline is usually a network problem, not dead hardware: wrong subnet, dropped scan traffic, a firewall, or a duplicate ID.
• Two devices have the same BACnet Device ID — what do I do?
  A BACnet Device ID must be unique network-wide.
• Does Easy BACnet support MS/TP or RS-485?
  No.
• Who do I call when something's wrong — IT, HVAC, or the controls contractor?
  Most BACnet IP problems belong to IT/network, the HVAC contractor, or the controls/BMS integrator.

Writing and overrides

• Is it safe to write to a BACnet point?
  Reading BACnet doesn't change anything.
• How do I write to a BACnet point with Easy BACnet, and release it afterwards?
  Turn on write mode, choose a priority, confirm the write, then the part people forget: release the point back to automatic control before you leave.
• Why is my BACnet point stuck, and how do I release an override?
  How the BACnet priority array works, why a commanded point stays commanded, and how to release an override by writing NULL at the same priority level.
• Why doesn't my BACnet value change when I write to it?
  You wrote a BACnet point and nothing changed.
• What does BACnet 'Write Access Denied' mean, and how do I fix it?
  Write Access Denied means the BACnet property cannot be written that way: usually an input point, a read-only object, or a vendor lock on the point.

Custom remotes and control panels

• How do I build a custom remote for a BACnet IP device in Easy BACnet?
  Step by step: build a drag-and-drop control screen for one BACnet IP device.
• How do I build a custom BACnet control panel for several devices in Easy BACnet?
  Beta: build one live control screen for up to 32 BACnet IP devices with the Control Panel Builder.

BACnet reference

• What do the BACnet object types mean?
  Reference table of BACnet object types: Analog and Binary Input/Output/Value, Multi-state, Device, Schedule, Trend Log and the rest, with what each is for.
• What is a BACnet Device ID, and why do duplicates matter?
  A BACnet Device ID (device instance) uniquely identifies a controller across the whole network.
• What do the units on a BACnet point mean?
  BACnet analog points carry an engineering-units code: degrees F, inches of water, %RH, CFM and many more.
• What are BACnet Who-Is and I-Am?
  Who-Is is a broadcast asking which devices exist; each replies I-Am with its instance, vendor and capabilities.
• What port does BACnet IP use?
  The default BACnet port is UDP 47808 (0xBAC0).
• BACnet MS/TP vs BACnet/IP — what is the difference?
  BACnet/IP runs over Ethernet on UDP 47808; MS/TP runs over an RS-485 twisted pair.
