EasyIO FC-20 Controller (fixed BACnet object register) BACnet points list
Updated 7 November 2026
Short answer
The FC-20 register lists the fixed BACnet objects the controller serves: 12 universal inputs (AI 1-12), 12 digital inputs (BI 1-12), 4 analog and 4 digital outputs, 64 analog value registers and 32 binary value registers for passing data to and from the program, and configuration objects for each input and output (signal type, scaling, offset, temperature table, digital on/off levels, linear and reverse settings, output interlock delays). What the registers mean depends on the program loaded in the controller.
This page lists 249 BACnet objects for the EasyIO FC-20 Controller (fixed BACnet object register) — 116 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from EasyIO’s own free documentation, linked below.

BMS integration notes: EasyIO FC-20 Controller (fixed BACnet object register)
Integration in brief
Set each universal input type (MV 1-12) and analog output type (MV 13-16) to match the wiring, then read the inputs (AI 1-12, BI 1-12) and command the outputs (AO 1-4, BO 1-4) or exchange data with the program through the AV and BV registers.
Minimum points to map
The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.
| Object | Name | Why | Access |
|---|---|---|---|
| BO 1 | DO 1 | Digital output 1 command | Command |
| AO 1 | AO 1 | Analog output 1 command | Command |
| AV 33 | AVOS 1 | First writable analog register to the program | Write |
| BV 18 | BO Reg 1 | First writable binary register to the program | Write |
| AI 1 | UI 1 | Universal input 1 value | Read |
| BI 1 | DI 1 | Digital input 1 state | Read |
| AV 1 | AVIS 1 | First read-only analog register from the program | Read |
Network setup
- UI n Type (MV 1-12): 1 = 0-10 V, 2 = 0-5 V, 3 = 0-20 mA, 4 = 4-20 mA, 5 = resistance, 6 = temperature sensor.
- AO n Type (MV 13-16): 1 = voltage, 2 = 0-20 mA, 3 = 4-20 mA.
Watch out for
- When a program in the controller drives an output, a BMS write to that output may be overwritten.
- The AV/BV registers carry no fixed meaning; get the program's point map from whoever wrote it.

Integration notes
- AVIS/AVIF (AV 1-32) and BI Reg (BV 2-17) are read-only registers; AVOS/AVOF (AV 33-64) and BO Reg (BV 18-33) are writable. Their meaning is set by the controller program.
- The register shows multistate objects as MSV; they are listed here as MV. The change log says the multistate objects became read/write in January 2015.
- The UI scaling, offset and DI level AVs are marked read only in the register, while the TempTable, AO scaling and DO delay AVs are read/write.
- The register does not state the BACnet transport or device instance.
- The register is published by EasyIO on the Johnson Controls documentation site.
Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the EasyIO FC-20 Controller (fixed BACnet object register) and exports what it actually has to Excel — free.

Questions about the EasyIO FC-20 Controller (fixed BACnet object register)
How many BACnet points does the EasyIO FC-20 Controller (fixed BACnet object register) have?
This list has 249 BACnet objects: 12 analog inputs, 4 analog outputs, 148 analog values, 12 binary inputs, 4 binary outputs, 53 binary values, 16 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which EasyIO FC-20 Controller (fixed BACnet object register) BACnet points are writable?
116 of the 249 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done.
Where is the official EasyIO FC-20 Controller (fixed BACnet object register) BACnet documentation?
The source is EasyIO FC 20 BACnet Register (v1.3), revision 2018-01-17, published free by EasyIO at https://docs.johnsoncontrols.com/bas/api/khub/documents/BrE3~ppu1b~p2ibfJarlEQ/content.
What are the minimum BACnet points to integrate the EasyIO FC-20 Controller (fixed BACnet object register)?
Start with BO 1 DO 1 (Digital output 1 command); AO 1 AO 1 (Analog output 1 command); AV 33 AVOS 1 (First writable analog register to the program); BV 18 BO Reg 1 (First writable binary register to the program); AI 1 UI 1 (Universal input 1 value); BI 1 DI 1 (Digital input 1 state); AV 1 AVIS 1 (First read-only analog register from the program).
How do I check these points on the real EasyIO FC-20 Controller (fixed BACnet object register)?
Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
