Problem

• (x ) bug report => please search github for a similar issue or PR before submitting

• ( ) unexpected behavior => please visit the Wiki before

  Current behavior When sending information from BACnet Write node the following error occurs "Error: BacnetAbort - Reason:4"

  Expected behavior I was passing a msg.payload to change the value of a Analog Value, app tag real, Present Value

  Minimal reproduction of the problem with instructions

  1. any time I try to send data through the node.

@biancode I think the issue is with Bacstack not transmitting Segmented data for the Write node. What do you think?

[Navybrandon]

I have fixed this issue.

[biancode]

@Navybrandon would you share here, how you fixed your issue?

[Navybrandon]

@biancode I would love too. But way too many steps to list here. In short made sure the bacstack folder was in 3 locations on my pi. then added bacnet:require('backstack') to my settings.js file under FunctionGlobalContext. for each of the three locations. FYI this breaks the modules you made. Then I had to create a function module for each read and Write I wanted. Please feel free to direct message me for more details i would to help in any way I can.

@Navybrandon @biancode Hi I think this is related to closed issue #8 and was previously identified as an issue with the Bacstack library

[vigalent]

@Navybrandon @mtoko Was a solution to this problem ever found. I can write a fixed value, but cant write a variable payload. Also, it only seems to read from AV's and BV's?

I was struggling to write to my BACnet ANALOG OUTPUT - it would work with a fixed value in the BACnet Write Node's 'Value' field but using msg.payload wouldn't get through. I worked out that the write node needs to be sent an array which includes the 'type' So my required numeric value has to go through a Function Node like this:

msg.payload = { values: [ { type: 4, // BACnet 'REAL' type value: msg.payload // Use the payload value directly } ] }; return msg;

NOTE: In order for this to work the 'App-Tag' field has to be set at NULL or 0 and the 'Value' field has to be empty.

Hi Friend, Can you share your flow or Images of write node please ?

Well I hope this makes sense - I'm just using a slider in NodeRed to override the Analog Output on my BACnet device — which is usually controlled by the building management system.

My slider is manually overriding the building control BACnet device, so when I want to relinquish control back to it I have to send a NULL.
