Yaskawa SI-B3/V BACnet MS/TP option (V1000 drive) BACnet points list
Updated 6 November 2026
The SI-B3/V is the V1000 version of Yaskawa's BACnet MS/TP option card. Its fixed object list mirrors the drive's Modbus registers: analog and digital I/O, run/fault/reset commands, frequency and PI setpoint references, output monitors, fault and status flags, and (on newer option software) energy, run-time and fault-code objects. AV29/AV30 give generic access to any drive parameter.
This page lists 120 BACnet objects for the Yaskawa SI-B3/V BACnet MS/TP option (V1000 drive) — 31 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Yaskawa’s own free documentation, linked below.

BMS integration notes: Yaskawa SI-B3/V BACnet MS/TP option (V1000 drive)
Fit the SI-B3/V, set the MS/TP address in F6-45, the baud rate in F6-46 and the device instance in F6-48/F6-49, and power-cycle. Set b1-01 = 3 and b1-02 = 3 (Option PCB) so BACnet supplies the frequency reference and run command. Write BV1 Run FWD Cmd and AV2 Frequency Cmd, read BV13/BV16 and AV10/AV12/AV13, and reset faults with BV4.
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 1 | Run FWD Cmd | Start/stop from the BMS (drive) | Command |
| AV 2 | Frequency Cmd | Frequency reference, units per o1-03 | Command |
| BV 4 | Fault Reset Cmd | Reset a tripped drive | Command |
| BV 13 | RUN-STOP | Running status | Read |
| BV 15 | READY | Drive ready to run | Read |
| AV 10 | Output Frequency | Output frequency, units per o1-03 | Read |
| AV 12 | Output Current | Motor amps | Read |
| AV 13 | Output Power | Drive power in kW | Read |
| BV 16 | FAULT | Any active drive fault | Read |
| AV 40 | Last Drive Fault | Most recent fault code | Read |
Enable & remote start
b1-01 Frequency Reference Selection = 3 (Option PCB) and b1-02 Run Command Selection = 3 (Option PCB); both default to 1 (terminals). b1-15/b1-16 = 3 do the same for External Reference 2. Monitoring, parameter access, fault set/reset and the multi-function inputs work at any time.
Heartbeat & communication loss
The drive raises bUS (Option Communication Error) when the link drops after communication was established, but only when the run command or frequency reference comes from the option (b1-01 = 3 or b1-02 = 3). F6-04 sets the bUS delay (default 2.0 s) and F7-16 a communication-loss timeout (0.0-30.0 s, default 0 = off, option software VST800265+); the fault is sent after F7-16 + F6-04. F6-01 = 3 or higher makes bUS an alarm only; F6-14 = 1 resets the fault when communication returns.
Sensors & values from the BMS
AV3 PI Setpoint Cmd lets the BMS write the PI setpoint (0-100 %); BO4 Ref Sel: PI Setpoint (or AV5 bit 1) selects it.
Network setup
- F6-45 sets the MS/TP MAC address (0-127, default 1).
- F6-46 sets the baud rate (default setting 3 = 9600 bps); the PICS lists 9600, 19200, 38400 and 76800 bps.
- Device instance = F6-48 (low word) + F6-49 (high word), in hex; default 1. Example: 1234 is F6-48 = 4D2H, F6-49 = 0.
- F6-47 sets the drive transmit wait time (5-65 ms, default 5 ms).
- Cycle power after changing these settings; the option reads F6-01, F6-04, F6-14 and F7-16 only at power-up.
- Up to 127 drives per MS/TP segment; the device object name (20 characters) is writable and takes effect after a power cycle.
Watch out for
- F6-01 set to alarm only keeps the drive running after a communication fault.
- BV56 Parameter Enter writes EEPROM (rated about 100,000 writes); don't use it cyclically.
- Several objects only exist with newer option software (VST800265 / VST800266).
- BACnet inputs and the S terminals are ORed together.

Integration notes
- Objects named Not Used (AI3-AI5, AO2, AV31, AV32, AV34, AV41, BI10-BI27, BI30) are left out.
- This table differs from the A1000/P1000 SI-B3 list: V1000 names use PI rather than PID, BO2/BO3 drive terminals P1-PC/P2-PC, AO2 is not used, BV42/BV43 show COM/LOCAL the other way round, and BV57 Drive Comms Error is added.
- AV1, AV4 and AV5 are packed command words; don't combine them with the single-bit objects they duplicate.
- Frequency units follow the drive's o1-03 display setting.
- Each description gives the drive Modbus register where the manual lists one (hex).
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 SI-B3/V BACnet MS/TP option (V1000 drive) and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.
Questions about the Yaskawa SI-B3/V BACnet MS/TP option (V1000 drive)
How many BACnet points does the Yaskawa SI-B3/V BACnet MS/TP option (V1000 drive) have?
This list has 120 BACnet objects: 6 analog inputs, 1 analog output, 38 analog values, 11 binary inputs, 7 binary outputs, 57 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Yaskawa SI-B3/V BACnet MS/TP option (V1000 drive) BACnet points are writable?
31 of the 120 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 Yaskawa SI-B3/V BACnet MS/TP option (V1000 drive) BACnet documentation?
The source is YASKAWA AC Drive V1000 Option BACnet MS/TP Installation & Technical Manual, Type SI-B3/V (TOEP YAICOM 19B), revision 2017-12, published free by Yaskawa at https://www.yaskawa.com/delegate/getAttachment?documentId=TOEPYAICOM19&cmd=documents&documentName=TOEPYAICOM19.pdf.
What are the minimum BACnet points to integrate the Yaskawa SI-B3/V BACnet MS/TP option (V1000 drive)?
Start with BV 1 Run FWD Cmd (Start/stop from the BMS (drive)); AV 2 Frequency Cmd (Frequency reference, units per o1-03); BV 4 Fault Reset Cmd (Reset a tripped drive); BV 13 RUN-STOP (Running status); BV 15 READY (Drive ready to run); AV 10 Output Frequency (Output frequency, units per o1-03); AV 12 Output Current (Motor amps); AV 13 Output Power (Drive power in kW); BV 16 FAULT (Any active drive fault); AV 40 Last Drive Fault (Most recent fault code).
How do I enable BMS control of the Yaskawa SI-B3/V BACnet MS/TP option (V1000 drive)?
b1-01 Frequency Reference Selection = 3 (Option PCB) and b1-02 Run Command Selection = 3 (Option PCB); both default to 1 (terminals). b1-15/b1-16 = 3 do the same for External Reference 2. Monitoring, parameter access, fault set/reset and the multi-function inputs work at any time.
Does the Yaskawa SI-B3/V BACnet MS/TP option (V1000 drive) need a BACnet heartbeat or have a communication timeout?
The drive raises bUS (Option Communication Error) when the link drops after communication was established, but only when the run command or frequency reference comes from the option (b1-01 = 3 or b1-02 = 3). F6-04 sets the bUS delay (default 2.0 s) and F7-16 a communication-loss timeout (0.0-30.0 s, default 0 = off, option software VST800265+); the fault is sent after F7-16 + F6-04. F6-01 = 3 or higher makes bUS an alarm only; F6-14 = 1 resets the fault when communication returns.
Can the BMS supply sensor values to the Yaskawa SI-B3/V BACnet MS/TP option (V1000 drive)?
AV3 PI Setpoint Cmd lets the BMS write the PI setpoint (0-100 %); BO4 Ref Sel: PI Setpoint (or AV5 bit 1) selects it.
How do I check these points on the real SI-B3/V BACnet MS/TP option (V1000 drive)?
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.
