    How to access priority array from Niagara superior?

    As the title says, is there any way to access bacnet priority arrays on points brought in from JACES to the supervisor?

    Thanks in advance 😊

    Not sure what you are asking.

    Do you want to see at what priority level a BACnet point is being written at? Or are you asking how to write at different BACnet priority levels at the supervisor level?

    When you learn in Bacnet points as writable, there will be slots for priority 16 and 10 (I think) left open. You can right click the point and pin slots to expose more slots for writing. Drop a link from whatever to those slots and that is the priority you are writing to. Pick one. It is easy.
    If you need to reach down into the controller and see which priority levels are being written to down there, you need to expand the virtuals under the controller. Little ghost icon. It will show the priority array with data that is being written to at each point.
    Hmmmm....smells like numbatwo to me.

    So weird.
    I've asked this exact question (not necessarily for Niagara, but for other integration projects) and everyone scratches their head - "huh?"

    I was on the phone with Above Air tech support trying to figure out how to make the units work. They do a bunch of funky stuff with Read-only and R/W points.
    I noticed on Yabe nothing showed up for Priority Array.
    He had no idea what I was talking about.

    I thought one of the basic, fundamental rules/principles for BACnet was the priority array. It goes from BN16 to BN01.
    BN15 overrides BN16, BN14 overrides BN15 and so on

    Your question is pretty simple to me
    "How to view and/or command the priority array of the BACnet points?"

    A table or little drop down menu. Want to command at BN08? Click the box for BN08.

    At the JACE level sure, those are BACnet points, he is trying to write at the supervisor level which is a Niagara network point and not a BACnet point.

    Oh ok. To be fair, the JACE is a supervisor as well. He wants to write to Niagara points.
    You cannot write to Niagara points. If you want to write to the values behind them, you need to do it down at the JACE while the point is still BacNet or whatever.
    The end result of this is that logic stays out of the server which is a good thing.
