Equipment symbols
The built-in P&ID equipment symbols you can place on a page, and the live states they reflect.
The page editor includes a library of equipment symbols — schematic shapes for the components of a building’s mechanical systems. Pick one from the Assets menu and place it on a page to build a process diagram (a P&ID), then bind it to tags so it shows live data and state.
The symbol library
The symbols are drawn with the page’s color, so they sit cleanly on a light or dark page. Some are general building-services components (pump, fan, valve, damper, heat exchanger, boiler); others are refrigeration-circuit components (compressor, condenser, evaporator); and a few are indicators (sensor, meter, manometer, LED, state indicator) rather than plant.
Live states
Beyond their static shape, some symbols reflect live state by binding a state to a tag or expression. When the bound value is true, the symbol changes to show it:
| State | What it shows | Symbols |
|---|---|---|
| Enabled | The component is running or active (the shape fills in). | Pump, Fan, Compressor, Valve 2 ports, Valve 3 ports, Valve 3 ports mirrored, Damper, Damper with spring return, LED |
| Manual | The component is in manual mode (a yellow outline). | All of the above, plus Manometer, Energy meter, Heater cooling, Valve check |
| Energized | The component is energized. | Damper with spring return |
| Modulating | It is modulating rather than fully open or closed. | Damper, Damper with spring return |
Set each state in the symbol’s State properties. An LED adds an Enabled color, so its lit color can differ from symbol to symbol.
Two symbols are both called Fan: the one under System takes states, and the animated one under Dynamic does not. If a fan won’t accept a binding, you’ve placed the animated one.
Symbols not listed above — tanks, heat exchangers, filters, sensors, the state indicator — have no built-in states. Drive their appearance with conditions instead.
Labels and alarms on a symbol
A symbol can carry labels (placed top, bottom, left, or right) that show a tag’s value beside it, and alarm indicators that light up when an associated alarm is active — so a single symbol shows what the component is, what it’s doing, what it reads, and whether it needs attention.
Setting all of that up by hand for every symbol on a plant diagram is the slow way to build a page. If your tags follow a naming convention, automation rules attach the tags, the alarms, and the labels in one step.
