Niagara Tip – Writing to BACnet Priority 10
I have found that using the Set feature in Niagara does not always write to BACnet priority 10.
By doing this you can still use Set in Niagara/ Tridium graphics
A simple workaround I use is to create a link within the Bacnet Setpoint block so the Out value feeds back into In10.

How to do it
Add a Bacnet block.
Right-click the block and select Link Mark.
Right-click again and choose Link From "BacnetSetpoint".
In the link window, select:
Source: Out
Target: In10
Click OK.
This creates a link from:
BacnetSetpoint.out -> BacnetSetpoint.in10
Notes
This is a handy workaround when Niagara is writing to Bacnet controller points
Be careful using this if the point is also being written to from another source. If there are two active writes on the same point, the value may jump around or behave unpredictably.
