Greenheck Vari-Green Drive VGD-100+ BACnet points list
Updated 7 November 2026
The Vari-Green Drive is a fan drive with built-in BACnet MS/TP. It works as an MS/TP master, and when set to accept remote commands it can be started, stopped and reset over the network. The printed parameter code list is short: output frequency, digital I/O status, output and system status, run/stop, fault reset and the fault code.
This page lists 12 BACnet objects for the Greenheck Vari-Green Drive VGD-100+ — 2 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Greenheck’s own free documentation, linked below.

BMS integration notes: Greenheck Vari-Green Drive VGD-100+
Set the drive to accept remote commands, then start and stop it with MV 56 and clear faults with MV 57. Read AV 42 output frequency, MV 52 system status and MV 62 fault code.
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 |
|---|---|---|---|
| MV 56 | Run/Stop | Run/stop command (1 = run) | Write |
| MV 57 | Reset Fault | Fault reset (1 = reset) | Write |
| MV 52 | System Status | Drive state (stop, run, fault, shutdown) | Read |
| AV 42 | VFD Output Frequency | Output frequency, Hz | Read |
| MV 62 | Fault | Active fault code (0 = none) | Read |
Enable & remote start
The drive must be set to accept commands via remote communications before BACnet run/stop and fault reset commands take effect.
Heartbeat & communication loss
Fault code 51 is BMS Communications Loss; the manual gives no timeout value.
Network setup
- BACnet MS/TP master; up to 128 master devices on a network.
- End-of-line resistor is set with the EOL DIP switch (default off).
Watch out for
- Only a short parameter code list is published; frequency or PID setpoint objects are mentioned but not printed.

Object ID lookup: Greenheck Vari-Green Drive VGD-100+ point IDs by name
Integration notes
- The manual also names positive integer value and character string objects among the supported types, but only the objects listed here are printed.
- The run/stop, reset and fault objects (56, 57, 62) follow the multi-state table on the next page with no new heading; they are listed as MV. Their printed states start at 0.
- An on-board DIP switch adds or removes the MS/TP end-of-line resistor.
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 Vari-Green Drive VGD-100+ and exports what it actually has to Excel — free. New to BACnet?

Questions about the Greenheck Vari-Green Drive VGD-100+
How many BACnet points does the Greenheck Vari-Green Drive VGD-100+ have?
This list has 12 BACnet objects: 1 analog value, 6 binary inputs, 5 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Greenheck Vari-Green Drive VGD-100+ BACnet points are writable?
2 of the 12 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 Greenheck Vari-Green Drive VGD-100+ BACnet documentation?
The source is Vari-Green Drive (VGD-100+) Installation, Operation and Maintenance Manual (481200 Rev. 5), revision 2020-04, published free by Greenheck at https://content.greenheck.com/public/DAMProd/Original/10001/481200VGDrive_iom.pdf.
What are the minimum BACnet points to integrate the Greenheck Vari-Green Drive VGD-100+?
Start with MV 56 Run/Stop (Run/stop command (1 = run)); MV 57 Reset Fault (Fault reset (1 = reset)); MV 52 System Status (Drive state (stop, run, fault, shutdown)); AV 42 VFD Output Frequency (Output frequency, Hz); MV 62 Fault (Active fault code (0 = none)).
How do I enable BMS control of the Greenheck Vari-Green Drive VGD-100+?
The drive must be set to accept commands via remote communications before BACnet run/stop and fault reset commands take effect.
Does the Greenheck Vari-Green Drive VGD-100+ need a BACnet heartbeat or have a communication timeout?
Fault code 51 is BMS Communications Loss; the manual gives no timeout value.
How do I check these points on the real Vari-Green Drive VGD-100+?
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.
