BMS integration notes: Cleaver-Brooks LCS Level Control System (ProtoNode)
Read-only. Map tank levels and setpoints, valve position, the common alarm and the alarm word.
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.

Network setup
- BACnet Device Instance = the controller's Modbus Node-ID + Node_Offset (default 50,000), so Node-ID 1 = 50001. Change Node_Offset in the ProtoNode web configurator to pick other instances.
- The ProtoNode RER does BACnet MS/TP or BACnet IP, selected on its S bank DIP switches.
- BACnet MS/TP: one MAC address (1-127) for the whole ProtoNode on the A bank DIP switches; baud on B0-B3 (38400 factory default).
- BACnet IP: default ProtoNode address 192.168.1.24; change it in the web configurator.

Integration notes
- Each Cleaver-Brooks controller on the ProtoNode is its own BACnet device; the object instances below are the same on every device.
- The profile has only AI and BI objects and the guide marks none as write points, so all are read-only.
- The guide gives no engineering units or state texts; units appear only where the object name carries them (DEG F / DEG C).
- Where a description is filled in, it gives the register from the guide's Modbus column.
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 LCS Level Control System (ProtoNode) 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 Cleaver-Brooks LCS Level Control System (ProtoNode)
How many BACnet points does the Cleaver-Brooks LCS Level Control System (ProtoNode) have?
This list has 59 BACnet objects: 9 analog inputs, 50 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Cleaver-Brooks LCS Level Control System (ProtoNode) BACnet points are writable?
None of the listed objects are marked writable in the source documentation.
Where is the official Cleaver-Brooks LCS Level Control System (ProtoNode) BACnet documentation?
Cleaver-Brooks does not publish it on its own website. This list comes from Cloud Enabled ProtoNode Gateway Startup Guide (RER/LER) for interfacing Cleaver-Brooks products (750-426), revision 03/2018, a copy hosted by watmfg.com at https://watmfg.com/watmfg23082016/wp-content/uploads/2016/09/750-426-ProtoNode-Cloud.pdf. Ask Cleaver-Brooks or its representative for the current revision.
What are the minimum BACnet points to integrate the Cleaver-Brooks LCS Level Control System (ProtoNode)?
Start with AI 101 Tank 1 Level (Tank 1 water level); AI 108 Tank 1 Level Setpoint (Tank 1 level setpoint); AI 103 Primary Valve Postion (Primary valve position); BI 230 Common Alarm (Common alarm); AI 107 Alarm Word (Alarm word).
How do I check these points on the real LCS Level Control System (ProtoNode)?
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.
