WEG CFW-11 (BACnet MS/TP) BACnet points list
Updated 4 November 2026
The CFW-11 runs BACnet MS/TP on its RS-485 port and maps drive parameters to fixed objects: AVs for readings, temperatures, hour and energy counters, ramps, PID values, SoftPLC parameters and the network speed reference; BVs for the status word (P0680) and control word (P0682); plus digital and analog I/O. A mailbox (AV 30/31, BV 33/34) reads or writes any parameter by number.
This page lists 116 BACnet objects for the WEG CFW-11 (BACnet MS/TP) — 35 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from WEG’s own free documentation, linked below.

BMS integration notes: WEG CFW-11 (BACnet MS/TP)
Set P0312 = 3 (BACnet MS/TP), the address in P0308 and the baud rate in P0310, then set P0220-P0228 so run/stop, direction and reference come from the serial port. Write BV 16 run/stop with BV 17 general enable and the speed reference to AV 29 (8192 = synchronous speed). Read BV 8, AV 3, AV 1 and BV 15, and reset faults with BV 23.
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 16 | Run/Stop | Start/stop from the BMS | Command |
| BV 17 | General Enabling | General enable; must be on to run | Command |
| BV 20 | LOC/REM | Remote mode when P0220 selects serial | Command |
| AV 29 | Serial/USB Speed Ref. | Speed reference, 8192 = synchronous speed | Command |
| BV 23 | Fault reset | Reset a tripped drive | Command |
| BV 8 | Ramp Enabled (RUN) | Running status | Read |
| AV 3 | Motor Frequency | Output frequency in Hz | Read |
| AV 1 | Motor Current | Motor amps | Read |
| BV 15 | Fault condition | Any active drive fault | Read |
| AV 19 | Present Fault | Active fault number | Read |
Enable & remote start
The drive only obeys the network when P0220-P0228 select the serial option for local/remote, reference, direction and run/stop. It needs both BV 17 General Enabling and BV 16 Run/Stop; BV 20 LOC/REM switches to remote when P0220 takes local/remote from the serial control word.
Heartbeat & communication loss
P0314 Serial Watchdog (0.0-999.0 s, 0 = off, factory 0.0): if no valid telegram arrives within that time the drive shows alarm A128 (or fault F228) and runs the P0313 action: 0 none, 1 ramp stop (factory), 2 general disable, 3 go to local, 4 local keeping commands, 5 fault. Timing starts at the first valid telegram after power-up.
Sensors & values from the BMS
AV 26 Keypad PID Setpoint can be written when the drive's PID is used; there is no separate network PID feedback object.
Network setup
- P0312 = 3 (BACnet MS/TP); P0308 MS/TP address 0-254 (factory 1).
- P0310 baud 9600, 19200 (factory), 38400 or 57600; P0311 must be 0 (8 bits, no parity, 1 stop).
- Device instance: P0760 x 10000 + P0761; with both at 0 the drive uses 359000 + P0308 (WEG vendor ID 359).
- P0762 max master (factory 127), P0763 max info frames, P0764 I-Am at power-up (factory) or continuously.
Watch out for
- Speed reference AV 29 is a 13-bit value, not Hz or %: 8192 = motor synchronous speed; negative values reverse.
- Ramp times, PID gains and the mailbox write change drive parameters; don't write them cyclically.
- P0313 = 0 keeps the drive running at the last command after a comm loss.
- P0311 is printed with default 1 (even parity), although its note calls option 0 the default; BACnet needs 0.

Integration notes
- The manual calls the object types ANI, ANO, ANV, BIN and BOUT; they are standard AI, AO, AV, BI and BO objects.
- Reserved objects are listed as printed; BI 11 and BI 27 are not in the binary input tables.
- AV 16 kWh Output Energy is printed with unit 'H'; it is an energy counter.
- Mailbox: write the parameter number to AV 30, then 1 to BV 33 to read it into AV 31, or set AV 31 and write 1 to BV 34.
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 CFW-11 (BACnet MS/TP) and exports what it actually has to Excel — free. New to BACnet?

Questions about the WEG CFW-11 (BACnet MS/TP)
How many BACnet points does the WEG CFW-11 (BACnet MS/TP) have?
This list has 116 BACnet objects: 4 analog inputs, 4 analog outputs, 38 analog values, 31 binary inputs, 5 binary outputs, 34 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which WEG CFW-11 (BACnet MS/TP) BACnet points are writable?
35 of the 116 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 WEG CFW-11 (BACnet MS/TP) BACnet documentation?
The source is BACnet CFW-11 User's Manual (10000831662 / 03), revision 2014-02, published free by WEG at https://static.weg.net/medias/downloadcenter/hbf/h72/WEG-cfw11-bacnet-manual-10000831662-en.pdf.
What are the minimum BACnet points to integrate the WEG CFW-11 (BACnet MS/TP)?
Start with BV 16 Run/Stop (Start/stop from the BMS); BV 17 General Enabling (General enable; must be on to run); BV 20 LOC/REM (Remote mode when P0220 selects serial); AV 29 Serial/USB Speed Ref. (Speed reference, 8192 = synchronous speed); BV 23 Fault reset (Reset a tripped drive); BV 8 Ramp Enabled (RUN) (Running status); AV 3 Motor Frequency (Output frequency in Hz); AV 1 Motor Current (Motor amps); BV 15 Fault condition (Any active drive fault); AV 19 Present Fault (Active fault number).
How do I enable BMS control of the WEG CFW-11 (BACnet MS/TP)?
The drive only obeys the network when P0220-P0228 select the serial option for local/remote, reference, direction and run/stop. It needs both BV 17 General Enabling and BV 16 Run/Stop; BV 20 LOC/REM switches to remote when P0220 takes local/remote from the serial control word.
Does the WEG CFW-11 (BACnet MS/TP) need a BACnet heartbeat or have a communication timeout?
P0314 Serial Watchdog (0.0-999.0 s, 0 = off, factory 0.0): if no valid telegram arrives within that time the drive shows alarm A128 (or fault F228) and runs the P0313 action: 0 none, 1 ramp stop (factory), 2 general disable, 3 go to local, 4 local keeping commands, 5 fault. Timing starts at the first valid telegram after power-up.
Can the BMS supply sensor values to the WEG CFW-11 (BACnet MS/TP)?
AV 26 Keypad PID Setpoint can be written when the drive's PID is used; there is no separate network PID feedback object.
How do I check these points on the real CFW-11 (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.
