Franklin Electric Cerus X-Drive VFD (embedded BACnet MS/TP) BACnet points list

Updated 12 November 2026

Short answer

The Cerus X-Drive has BACnet MS/TP built into its COM1 RS-485 port. The drive exposes only Analog and Binary Values: commandable AVs for the frequency reference and 16 block-transfer slots, read-only AVs for drive measurements and codes, commandable BVs for run, stop, direction and reset, and status BVs for faults, HOA position and pump modes such as pipe fill, sleep and broken pipe.

This page lists 80 BACnet objects for the Franklin Electric Cerus X-Drive VFD (embedded BACnet MS/TP) — 24 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Franklin Electric’s own free documentation, linked below.

BMS integration notes: Franklin Electric Cerus X-Drive VFD (embedded BACnet MS/TP)

Integration in brief

Set PLC Com Type to BACnet, the MAC, speed and device ID, then point the HOA source, speed references and run commands at RS485 Serial. Run with BV 7, give speed with AV 1 (with BV 0 set to use it), and read output frequency, current, faults and the HOA state.

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 7	Power Out CMD	Run command (1 = run, 0 = coast stop)	Command
BV 0	Freq Active CMD	Must be 1 to use the AV 1 frequency reference	Command
AV 1	FreqRefValue	Frequency reference, Hz	Command
BV 15	Reset	Fault reset (write 1)	Command
AV 31	Output Frequency	Output frequency, Hz	Read
AV 44	Output Current	Motor current, A	Read
BV 33	HOA in Auto	HOA switch in Auto	Read
BV 19	Error/Fault	Any error/fault active	Read
AV 43	Error Code	Fault code	Read

Enable & remote start

Set HOA Mode Source [SET-60] to RS485 Serial, Auto Speed Ref [SET-07] and Hand Speed Ref [SET-09] to RS485 Serial, and Auto/Hand Run Cmd [SET-08]/[SET-10] to RS485 Serial so BACnet can run the drive and set its speed.

Network setup

PLC Com Type [PLC-23] = 1_BACnet turns on BACnet on COM1 (8N1) and turns off Modbus and PLC comms on that port.
BACnet MAC ID [Comm-24]: default 10, range 0-127. Speed [Comm-25]: 9600, 19200, 38400 (default) or 76800.
Device instance = [Comm-27] x 1000 + [Comm-26] (0-4194303); Max Address [Comm-28] is the highest master on the trunk.
Enter the BACnet password at [Comm-29]; the keypad shows 8888 when setup is accepted.
COM1 is on terminals SG+/SG- or either RJ45 jack (pins 4 and 5).

Watch out for

BV 0 must be 1 or the drive runs at 0 Hz regardless of AV 1.
BV 22/23 are printed twice with different meanings; confirm which object holds the pump fault flags before mapping them.
Block transfer AVs (11-26) only carry data once mapped in the drive parameters.

Integration notes

The object numbering follows the Delta CP2000 BACnet map (delta-electronics/vfd-cp2000), but Franklin prints its own object names and uses objects the CP2000 leaves reserved or lacks: BV 20-21, BV 24-36 (pump faults, modes, HOA) and AV 70-71.
Reserved objects (AV 0, AV 2-10, AV 27-30, AV 32-34, AV 36-38, AV 40, BV 2, BV 5, BV 8-14, BV 37-39) are left out.
AV 11-26 are printed as one row (Block Transfer, mapping 1 to 16); their units depend on what each slot is mapped to.
The status table prints BV 022 and BV 023 twice (Q-Stop Mode / Power OUT, then Broken Pipe / Pipe Leak); both pairs are kept as printed. Check with a scan.
The commandable sections are marked RW and titled Commandable; they are listed as C.

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 Cerus X-Drive VFD (embedded BACnet MS/TP) and exports what it actually has to Excel — free.
