BACnet interface to Node RED

[Edward Vielmetti]

If anyone has any experience or suggestions interfacing to a system that runs BACnet, I'd appreciate the information.

There's a pile of code here

http://bacnet.sourceforge.net/

and it looks like it exports a command line interface, so as a first start I can see wrapping an "exec" node around those.

thanks

Ed

I've had limited BACnet experience connecting KNX to it.

Assume your reading values form a BACnet network over IP?

Then you need to be a BACnet Client.

If your trying to get values from sensors etc to a BACnet network your need to be a BACnet Server.

The interface doesn't support RS485 and there are a few different versions of this, 

Using their shell seems like a good place to start.

But there are always the C bindings for node.js

nikhilm.bitbucket.org/articles/c_in_my_javascript/c_in_javascript_part_1.html

Could you share a bit more about your requirement?

Edward,

Did you ever have any success with a BACnet interface?  I'm attempting to integrate bi-directional communication between node red and BACnet, but so far have not found anything that I'm able to get working.  My only option at this point is to use a modbus <--> bacnet gateway since I can't seem to find any other way of moving data.

Thanks

[Lawrence Griffiths]

Hi, short answer No.

I've done exactly what your thinking using Modbus TCP to BACnet 

I've been watching this project in the hope that at some point I could create a Node-RED wrapper for it.

This is interesting.  It seems that this here gentleman has figured something out that I have not been able to accomplish in over 2 months now.

[brettnreno]

Someone did it.  And I found it!  I'm so excited, now I just have to figure out how to actually use it.  It took me awhile to figure out how to install it since I'm still learning challenged in npm, but I first I ran " npm install --save bacstack " then I ran " https://github.com/goliatone/node-red-contrib-bacnet "  When I went back into my node red, the BACnet blocks were in my library.  I haven't been able to actually read or write data yet from any of my BACnet devices, but i'll play around with it more tomorrow.

[brettnreno]

I messed up the actual node red part.  It's " npm install https://github.com/goliatone/node-red-contrib-bacnet "

[Michael Dalby]

I'd be interested to hear how you get on with using the implementation as I am also interested in trying to get bacnet up and running at some point

Many thanks and good luck 

Michael

I have gone through, each post and tried to conenct to my BACnet interface using node red.

I have used below command.

https://github.com/goliatone/node-red-contrib-bacnet

But when I up the node red and run it locally, it is not showing the BACnet specific nodes, Appreciate any help.

Ishara

[Mark Setrem]

if you are following the command on the readme
you need to be in your .node-red folder.

if it is failing are there any error messages when you install it, or any error messages when you run node-red.

alternatively you can install the node using the "manage palette" option from the node-red menu.

if you need further help please include the version of node-red , nodejs and npm you are using and details of which platform you are running node-red on.

[RMVPAPS]

Hi, Were you able to get node-red-contrib-bacnet to work? I got the nodes installed and loaded in my node-RED and all but when trying to run discovery node or read node, I get reference error - this is not defined etc... Any help to get it to work is appreciated. I have at present used the bacstack module and created a custom node for reading property. 

[Alberto Gazzin]

Hi all,

I have attempt to install node-red-contrib-bacnet from https://github.com/goliatone/node-red-contrib-bacnet/blob/master/README.md, but I have the error:

Can someone help me to install in Node-Red?

My Node-Red version is 0.17.5

Node version 6.11.3

NPM version 3.10.10

Many thanks!

[Nick O'Leary]

The install section of its README says the following: https://github.com/goliatone/node-red-contrib-bacnet/blob/master/README.md#install

Install

NOTE: Currently the module is not published, so you would need to use the following command:

$ npm install goliatone/node-red-contrib-bacnet

Any success? I also get the error, reference undefined when I do a bacnet discovery.

Shows as connected to the bacnet server but not able to poll any bacnet points. Running latest node red on RPI 3.

[chris....@gmail.com]

I also cannot install node-red-contrib-bacnet follow above procedure.

if you read the end of the error message it should give you a hint.

 You need to have git installed if npm is going to install it direct from git.  On windows you will need to install it. 

A minute on google found this page that explains what you need to download and how to correctly set the PATH https://stackoverflow.com/questions/44388889/error-not-found-git-when-install-npm-package-on-windows

Yeah, agreed. Read the error people. Install isn't the issue, clearly says it's not in the repository, a git install is needed.

it's getting it to work. Keeps showing reference undefined when I try to bacnet discover or do a simple bacnet read and poll the bacnet server. A little help from the dev would be awesome.

[Colin Law]

Probably best to raise an issue against the node on github then.

@RMVPAPS @TridiumControls

regarding ReferenceError: this is not defined
on my system :
 Node-RED version: v0.17.5
 Node.js  version: v6.11.4
 Linux 4.4.0-96-generic x64 LE

the console log shows ::

   at Bacnet (/usr/lib/node_modules/node-red-contrib-bacnet/lib/bacnet.js:8:9)


super();
needs to be included before this can be called at line 8 in lib/bacnet.js

created a PULL request to GIT https://github.com/goliatone/node-red-contrib-bacnet

Although still having trouble getting a whois reply from the BACnet subnet on my second network card and IP
anyone have a clean working example of the configuration ?

[chris....@gmail.com]

I have changed some code in bacnet.js and it can work now. However it still have some issue on upd 47808 bind function. I need shutdown node-red and run again to assure the binding port release. Do you anybody how to solve it that I can deploy every time in node-red.

Best Regards,

Chris

Hi,

 

I have update the "node-red-contrib-bacnet" and support read, write and whoIs function. But it still have the folllowing small issue and welcome anyone test it and help me solve it.

 

Issue

1. cannot release socket UPD 47808  when deploy a flow

2. cannot well control each BacnetReadProperty return and match each read request

 

Guide

1. download the code from

link: http://pan.baidu.com/s/1pKTRFXD password: uzui

2. copy the folder to "C:\Users\xxxx\AppData\Roaming\npm\node_modules"

3. start node-red

4. inport flow JS as folllows
