How can i specify priority level when attempting a write from the misty bacnet console?

[khavernathy]

Also, how can I specify the priority level when attempting a write?

I have

> write 7 analogValue:5 presentValue 30                             
property: writeAccessDenied

but I think I need to change the priority to get it to work.

12.4.11 Priority_Array
This read-only property, of type BACnetARRAY[16] of BACnetOptionalReal, is an array that contains prioritized commands that are in effect for this object. See Clause 19 for a description of the prioritization mechanism.

19.2.1 Prioritization Mechanism
For BACnet objects, commands are prioritized based upon a fixed number of priorities that are assigned to command-issuing entities. A prioritized command (one that is directed at a commandable property of an object) is performed via a WriteProperty service request or a WritePropertyMultiple service request. The request primitive includes a conditional 'Priority' parameter that ranges from 1 to 16. Each commandable property of an object has an associated priority table that is represented by a Priority_Array property. The Priority_Array consists of an array of commanded values in order of decreasing priority. The first value in the array corresponds to priority 1 (highest), the second value corresponds to priority 2, and so on, to the sixteenth value that corresponds to priority 16 (lowest).

You are correct, but you also need to present your value as a Real rather than Integer. You might be getting that error because the server isn't providing the correct error core.

write [ ] [ ]

So you probably want something like:

> write 7 analogValue:5 presentValue 30.0 - 6

The hyphen for the indx indicates "skip this parameter, the next number is the priority.

thanks. this is good info but didn't quite get me to be able to write to presentValue. Still getting property: writeAccessDenied, and I tried with integer and float, and with priority 1 -> 16.

Are there any common mistakes when creating bacnet objects that make them non-writable? We've been at it for a few days with no luck trying to just write to the object.
