Create and interact with schematic diagrams of building systems with live data overlays in Cloud BMS.
System graphics are a building-level feature. Select a building from the sites list to access system graphics through the Systems module or Graphic Tool.
System graphics are schematic or P&ID-style visual diagrams of building systems with live data overlaid on equipment components. They provide a visual representation of how equipment is connected and operating, making it possible to monitor system health and diagnose issues at a glance.
Before creating a system graphic, make sure you have created a system in the Systems module. The graphic must be linked to an existing system.
1
Open the new graphic dialog
Navigate to Graphics in the left sidebar, select the Systems tab, and click New Graphic. You can also create a system graphic from within a system by navigating to the Graphics view and clicking + Create New.
2
Configure the graphic details
Enter the graphic name, select the system to link it to, and add an optional description. You can also upload a system file (such as a P&ID drawing) as a background by dragging and dropping or browsing for a file.
The New System Graphic dialog collects the graphic name, system assignment, description, and an optional system file upload
Upload a background image or P&ID drawing. Drag and drop a file, click Browse files to upload from your computer, or click Browse from files to select from previously uploaded files.
3
Open the Graphic Tool
Click Done to create the graphic and open it in the Graphic Tool editor.
The Devices tab lists all devices and points associated with the linked system. A green checkmark with a number indicates how many points from that device are already placed on the graphic.
The Devices tab shows system devices with their points, and the canvas displays the system schematic
Expand a device to see its points with current values. Drag a point onto the canvas to place a marker at the corresponding location on the schematic. Use the search, sort, and filter icons at the top of the device list to find specific devices or points.
The Elements tab displays reusable elements that have been saved to the graphic’s element library. Use this tab to search, select, and style placed elements. Selecting an element from the list highlights it on the canvas and opens the Marker Style panel on the right.
The Elements tab lists placed elements with options to search and style them using the Marker Style panel
Layers organize the system graphic into multiple views, reducing clutter on complex schematics. Click + Add Layer at the bottom right of the canvas to create a new layer.
The Create Layer dialog lets you name the layer, assign an icon, and optionally import devices from another layer
Copy device placements from an existing layer to use as a starting point for the new layer.
The Base Layer shows critical operating parameters
Additional layers contain supplementary data, tables, system markers linking to related systems, and diagnostic points
Use layer configurations in the Graphic Tool settings to pre-map device types and points to layers. Dropping a device onto a layer with a configuration automatically adds the correct point marker.
Overlays are additional visual layers that you can toggle on and off over the system graphic. Use overlays to display supplementary information such as duct routes, piping paths, or wiring diagrams without cluttering the main schematic. Click + Add Overlay at the bottom right of the canvas to create an overlay.
The canvas bottom bar shows the Base Layer selector alongside Add Layer and Add Overlay options
For more details on overlay configuration, see the Graphic Tool overlays documentation.
System markers act as navigation links between system graphics. They allow users to jump between related schematics or navigate from a floor plan directly to a system graphic.While editing a graphic, switch from Devices to Systems in the left-hand elements menu. Drag and drop a system onto the canvas to create a clickable navigation marker.
Cloud BMS uses a BACnet-inspired priority model for writable points. The same command dialog appears for BACnet and non-BACnet integrations, such as REST API thermostats. How each action maps on the device depends on the connector.BACnet points that accept commands have 16 priority levels (1 is highest, 16 is lowest). When every level is empty (null), the point uses a fallback / default value (Relinquish_Default in BACnet). That fallback is not a 17th BACnet priority. Some interfaces label it as level 17 for display only.Override and Set turn different knobs under the hood, even when the visible value looks the same.
Action
What it writes*
Description
Override
Priority 8*
Temporary exception in the priority array. Takes precedence over lower-priority automation.
Set
Fallback / default*
Changes the fallback or default value.
Auto
—
Clears an Override
Release
—
Clears a Set
*Typical for most BACnet and Niagara deployments. Connectors and site standards can differ.Override, Auto, and Set borrow Niagara-style action names. Release is a Cloud BMS action that clears a Set.In Niagara-style control, Set keeps a non-null fallback so sequences and logic keep a reliable baseline. Use the priority array (including Override) for programmed automation and temporary exceptions.To make Set write to priority 16 instead of the fallback or default, enable Set in Slot16 (Niagara) on the point. Configure that option from device details, device templates, or points batch update.
