Topic: Communication with arduino and OPC/SCADA? (Read 9279 times) previous topic - next topic

MrMr

Hi

I posted this in the wrong forum before, so repost here.

Is it possible to get the arduino to communicate to a OPC server? Or is there another way so that i can get the arduino to communicate to scada software like factory talk (Allen-Bradley)

Thank you

Mark

Does this help...

MrMr

Thanks for the answer. I think i could get the modbus into the SCADA. I will work and try to find a solution with modbus.

If there is anybody else that have done it some other way feel free to contribuete.

Hi All,

actually  we are working on the driver to communicate between ARDUINO and our visualization Software VisBee.
It's a fully loaded Visualization system for HMI and SCADA.

You can download the Software without any restrictions at www.visbee.de (english version)

The is a extra version for ARDUINO - Fans ;-)  (VisBee-light)

The driver will be available during march/april 2013.

If you have further questions let me know.....

BR,
Chris

MrMr

Thanks for the posts guys. I will look into it.

Looking forward to the driver VisBee and trying out your software. Could you post it here maybe when it is released?

VisBee

Sure I will,

our software engineer working on it.

What a shame VisBee only seems to operate on microsoft windows, I hope you are also looking to have it operate on other OS's.

Just like 'Citect SCADA' and the Allen Bradley RSLogix range of software products, they all only operate on windows, and this is the only reason I keep a windows image available in VirtualBox environment. I feel irked by having to keep software like this for work I do in Industrial Automation.

How wonderful it would be if we could have our operating system of choice and be able to use some of these programs.

Chris, a problem with your 'visbee' web site. If go to this page http://www.visbee.de/Christ/Christ-Elektronik/ and then select the English flag at the top of the page for English then all I get is a blank page. There are other pages that do the same, you will need to check to find out which pages do not work.

Hi Paul, thx for the infos! Ich will check the "Error" at our page.....

VisBee: thanks for your Feedback in this point, I will forward it to the "special forces team"

Hello

I am proud to present the first free OPC Server for Arduino. You can get more information from the Arduino OPC Server project page at:
http://www.ismsolar.com/arduino-opc-server

Now it is in beta stage so help is wanted to debug. The project is going to be Open Source and source will be published as soon as stable version will be released with your help (of course if you need the sources now you can contact with me).

If you use it please, tell me about that to improve it.

There is a forum of the project if you need some open support.

All the best

Hi ilde

Great work with the OPC Server. Works great.

The only thing I noted is, when using the OPC library with the One Wire Digital Temperature Sensor - DS18B20, the OPC Tag health change to "bad" each time the temperature is read from the DS18B20.

Can you please look into this if you get the same result.

Hello!

yes, i can imagine where is the bug in the Arduino OPC Server. Could you send me your sketch or al least the line where you create the OPC Item? AddItem(....

I am creating a new site for the Arduino OPC Server at:

http://www.ArduinoOPC.com/

so you could use the support forum for news, updates and bug fixes

All the best

Hi ilde

Please see my sketch below. Any suggestions are welcome.

Just to recap: when the piece of code "  if(currentMillis - previousMillis > 2000)" executes every 2 seconds the OPC tag quality changes from good to bad and back to good.

It seems like every time the onewire device is accessed the OPC quality changes.

Looking forward to your response.

Hi,

congrats to idle, nice work -ArduinoOPC -

I guess we are to late with integrating our Ardiuno script to communicate from VisBee to Arduino on direct way  :~

Anyway, with VisBee Visualisation you naw have to possibilities to communicate with Arduino Hardware.

1) Arduino OPC by ilde
2) Direkt with VisBee Skript (http://www.visbee.de)

However, have fun with your Arduino !

Here is a link to a sample I put together to talk to Arduino using the open source SCADA project I maintain. It can run on any computer running node JS. No special code such as modbus need to be loaded to the arduino. It uses the built in firmata driver!

https://github.com/vytronics-samples/arduino.scada

Review the readme file for install instructions.

See live demo here with driver in sim mode.

www.vytronics.com - there is a button to view the live demo.
