Wilo SC Lift (BACnet MS/TP / IP) BACnet points list

Updated 7 November 2026

Short answer

Wilo's SC-family switch boxes control multi-pump systems and act as a BACnet MS/TP slave on their RS-485 port; BACnet IP needs an added gateway in the panel. The SC Lift list covers the operating command, level setpoints, float switch states, pump state bits, running hours and error bits. Fieldbus write access is governed by a bus command timer that must be refreshed every five minutes.

This page lists 79 BACnet objects for the Wilo SC Lift (BACnet MS/TP / IP) — 20 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Wilo’s own free documentation, linked below.

BMS integration notes: Wilo SC Lift (BACnet MS/TP / IP)

Integration in brief

Map Drives on/off (BO 224) as the start/stop command. For fieldbus control, write Set to the Bus command timer (MO 208) and repeat it within five minutes. Read the collective run and fault signals (BI 976/977) and the Error state bits for alarms; acknowledge with BO 1985.

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.

Enable & remote start

The Bus command timer (MO 208) decides who may change settings. Manual: HMI and fieldbus both write, last value wins. Off: HMI locked, fieldbus only. Set: HMI locked and a 5-minute timer starts (state reads Active).

Heartbeat & communication loss

With the Bus command timer in Set mode, Set must be written again at least every five minutes. If it lapses the state changes to Reset, the HMI gets access back and the fieldbus is locked until Set is written again.

Integration notes

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 SC Lift (BACnet MS/TP / IP) and exports what it actually has to Excel — free. New to BACnet?

Questions about the Wilo SC Lift (BACnet MS/TP / IP)

How many BACnet points does the Wilo SC Lift (BACnet MS/TP / IP) have?

This list has 79 BACnet objects: 15 analog inputs, 12 analog outputs, 44 binary inputs, 3 binary outputs, 5 multi-state outputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Wilo SC Lift (BACnet MS/TP / IP) BACnet points are writable?

20 of the 79 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 Wilo SC Lift (BACnet MS/TP / IP) BACnet documentation?

The source is BACnet - supplemental sheet SC manual (SC System): System-specific data-point list BACnet SC (wilo110041 (OPTION BACnet SC 2539869 Ed. 06)), revision 2020-07-10 (list 31.200), published free by Wilo at https://cms.media.wilo.com/cdndoc/wilo110041/4721760/wilo110041.pdf.

What are the minimum BACnet points to integrate the Wilo SC Lift (BACnet MS/TP / IP)?

Start with BO 224 Drives on/off (Automatic operation and all pumps on/off); MO 208 Bus command timer (Write Set (3) at least every 5 min to keep control); BO 1985 Acknowledge (Alarm acknowledge); BI 976 Switch box state (SBM) (Collective run signal); AI 400 Current value (Measured value; unit follows the control mode); BI 1301 State Float switches (High water) (High water float switch); BI 977 Switch box state (SSM) (Collective fault signal).

How do I enable BMS control of the Wilo SC Lift (BACnet MS/TP / IP)?

The Bus command timer (MO 208) decides who may change settings. Manual: HMI and fieldbus both write, last value wins. Off: HMI locked, fieldbus only. Set: HMI locked and a 5-minute timer starts (state reads Active).

Does the Wilo SC Lift (BACnet MS/TP / IP) need a BACnet heartbeat or have a communication timeout?

With the Bus command timer in Set mode, Set must be written again at least every five minutes. If it lapses the state changes to Reset, the HMI gets access back and the fieldbus is locked until Set is written again.

How do I check these points on the real SC Lift (BACnet MS/TP / IP)?

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.
