Inlet and Outlet Properties
If you've got an asset that changes a process value (for example, a compressor that changes the pressure or a chiller that reduces the temperature), there's a valid reason that you'd want to see both the up-stream and the down-stream temperature when you look at the device itself.
But since the down-stream temperature measurement is often made in another asset and ARDI only allows one use of a property per asset, how on earth do you do that?
Using References
The documentation on references cover this exact scenario.
References allow you to display the property from a different asset on your dashboard. This means that you can actually have several measurements of the same type visible on the same dashboard.
So assuming you have the following situation…
You can add two references on Chiller - one named 'Inlet Temp.' that shows the temperature coming from Temp Sensor A, and one called 'Outlet Temp' that shows the temperature measured on Temp Sensor B, downstream.
