Toshiba International Q9 Plus ASD (embedded BACnet MS/TP) BACnet points list
Updated 6 November 2026
The Q9 Plus has BACnet MS/TP on the terminal board's S4 RJ-45 (RS-485) connector when F829 = 2 (BACnet). The object list covers the terminal inputs and relay outputs, status and command BVs (run/stop, direction, fault reset, preset speeds and command/frequency source overrides), the analog inputs and outputs, and AVs for drive monitors, Virtual Linear Pump values, frequency reference, fault codes and ramp times.
This page lists 64 BACnet objects for the Toshiba International Q9 Plus ASD (embedded BACnet MS/TP) — 17 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Toshiba International’s own free documentation, linked below.

BMS integration notes: Toshiba International Q9 Plus ASD (embedded BACnet MS/TP)
Set both SW200 switches ON, F802 to a unique station number, F827 = 0 (no parity) and F829 = 2 (BACnet), then reset with F899. Select RS485/BACnet as the command source (F003) and frequency source (F004), or use BV 22/BV 21 to override them. Write BV 10 Run/Stop Cmd and AV 16 Freq Ref, and read BV 0, AV 1, AV 4 and BV 2.
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 |
|---|---|---|---|
| BV 10 | Run/Stop Cmd | Start/stop command | Command |
| BV 22 | Cmd Ovrd | Overrides F003 command source | Command |
| AV 16 | Freq Ref | Frequency reference, Hz | Command |
| BV 21 | Freq Ovrd | Overrides F004 frequency source | Command |
| BV 14 | Fault Reset | Reset a tripped drive | Command |
| BV 0 | Run/Stop Status | Running status | Read |
| AV 1 | Output Freq | Output frequency, Hz | Read |
| AV 4 | Output Current | Motor amps | Read |
| BV 2 | Fault Status | Any active drive fault | Read |
| AV 18 | Last Flt | Active fault code | Read |
Enable & remote start
Run commands follow F003 Command Source (3 = RS485/BACnet) and speed follows F004 Frequency Command Source (6 = RS485/BACnet). BV 22 Cmd Ovrd and BV 21 Freq Ovrd override those selections from the network. BV 4 shows whether the drive is in local control.
Heartbeat & communication loss
F803 Communications Time-Out (0-100 s, default 0 = off) sets how long the RS-485 link may be idle; F804 Time-Out Action (default Trip/Trip) sets whether the drive does nothing, alarms or trips. Both need a power cycle to take effect.
Network setup
- Wire to the S4 RJ-45 on the terminal board: pin 4 RS485-A, pin 5 RS485-B, pins 2 and 8 GND. Both SW200 switches must be ON (2-wire).
- F802 ASD Number sets the station number (unique on the network; default 0).
- F827 = 0 (No Parity), F829 = 2 (BACnet), then F899 to reset the option board and drive.
- F820 sets the RS-485 baud rate (9600, 19200 or 38400 bps; default 19200).
- Communication parameter changes need a power cycle.
Watch out for
- F804 defaults to Trip/Trip, so with a timeout set in F803 the drive trips when the BMS stops talking.
- The manual does not list the default device instance or how it is set.

Integration notes
- From the Q9 Plus ASD Installation and Operation Manual (April 2020), BACnet I/O and Values, Tables 4-8 (PDF pp79-84). AV 17, AV 21 and AV 22 are not in the table.
- BI 3-5, BI 14-17, AI 3-4 and AO 2-3 need the ETB004Z expansion I/O card.
- The terminal functions in the descriptions (e.g. S1 Fire-speed, OUT 1 Open Damper) are the printed defaults and follow the terminal settings.
- AV 10 PID Fbck is printed with units Hz.
- Fault code meanings for AV 18-20 are in Toshiba's BACnet Option Unit Function Manual, not in this manual.
- Toshiba International (industrial drives) is a different company from the Toshiba Carrier VRF products listed under Toshiba.
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 Q9 Plus ASD (embedded BACnet MS/TP) and exports what it actually has to Excel — free. New to BACnet?

Questions about the Toshiba International Q9 Plus ASD (embedded BACnet MS/TP)
How many BACnet points does the Toshiba International Q9 Plus ASD (embedded BACnet MS/TP) have?
This list has 64 BACnet objects: 5 analog inputs, 4 analog outputs, 22 analog values, 18 binary inputs, 15 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Toshiba International Q9 Plus ASD (embedded BACnet MS/TP) BACnet points are writable?
17 of the 64 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 Toshiba International Q9 Plus ASD (embedded BACnet MS/TP) BACnet documentation?
The source is Q9 Plus ASD Installation and Operation Manual, BACnet Setup: BACnet I/O, and Values (Tables 4-8), revision 2020-04, published free by Toshiba International at https://toshiba.com/tic/wp-content/uploads/Q9_Plus_ASD_Installation_and_Operation_Manual.pdf.
What are the minimum BACnet points to integrate the Toshiba International Q9 Plus ASD (embedded BACnet MS/TP)?
Start with BV 10 Run/Stop Cmd (Start/stop command); BV 22 Cmd Ovrd (Overrides F003 command source); AV 16 Freq Ref (Frequency reference, Hz); BV 21 Freq Ovrd (Overrides F004 frequency source); BV 14 Fault Reset (Reset a tripped drive); BV 0 Run/Stop Status (Running status); AV 1 Output Freq (Output frequency, Hz); AV 4 Output Current (Motor amps); BV 2 Fault Status (Any active drive fault); AV 18 Last Flt (Active fault code).
How do I enable BMS control of the Toshiba International Q9 Plus ASD (embedded BACnet MS/TP)?
Run commands follow F003 Command Source (3 = RS485/BACnet) and speed follows F004 Frequency Command Source (6 = RS485/BACnet). BV 22 Cmd Ovrd and BV 21 Freq Ovrd override those selections from the network. BV 4 shows whether the drive is in local control.
Does the Toshiba International Q9 Plus ASD (embedded BACnet MS/TP) need a BACnet heartbeat or have a communication timeout?
F803 Communications Time-Out (0-100 s, default 0 = off) sets how long the RS-485 link may be idle; F804 Time-Out Action (default Trip/Trip) sets whether the drive does nothing, alarms or trips. Both need a power cycle to take effect.
How do I check these points on the real Q9 Plus ASD (embedded BACnet MS/TP)?
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.
