Hello guys .
Iam a college student from Tunisa .
I have a project to do .
I want create a communication between 5 atlas copco compressor with elektronikon 2 regulator and my laptop to control the compressor from my desk .
I have searched every thing about elektronikon 2 and i have not found any thing to help me .
Please guys if any one of you can help me contact me in here or with my gmail : [mod edit email address removed. Please send a PM if you wish to contact the OP, thank you]
Thank you very much .

Hello,

Try to find using "Remote monitoring"

Remote monitoring (optional).

Modbus and Profibus are among the standard communication protocols supported for the Elektronikon

Thank for responding me.
Can you explain more to me.

Have you talked to the service people who maintain your atlas copco compressor? They will have all the information you need, or can get it for you.

They didn't reply respond to me.

Try talking to them in person. Or the salesman for your area. They, as a company, are very responsive, if you find the right person. Do you not have documentation that came with the compressor?

It seems that there are ready-made solutions to meet this demand, it is probably not in the manufacturer's interest to have information available. But it is probably possible to observe a system at work and understand how it works.

I don't know if these docs will help you, but I found these guides:

I found these guides after seeing these posts:

That looks to be the same question as you asked here.

I have merged your cross-posts @rague.

Cross-posting is against the Arduino forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.

Repeated cross-posting can result in a suspension from the forum.

In the future, please take some time to pick the forum category that best suits the subject of your question and then only post once to that forum category. This is basic forum etiquette, as explained in the "How to get the best out of this forum" guide. It contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

hello guys.
please who knows how can i read the pressure and the temperature of an atlas copco compressor GA22 with an elektronikon mkII as a regulator from my laptop.
thanks guys.

Hi!

You have to show the specifications of the pressure sensor of your compressor.

The output of this type of sensor can be current or voltage.

In this example the output range is 4 to 20mA for 0 to 16 bar.

Thank you for your replie.
Can't i get the informations from the sensors that already in the compressor ?

You are not telling us the complete story. IF the compressor is in use, the sensors are in use right now.

I have merged your cross-posts @rague.

As I mentioned in my previous warning about cross-posting, repeated violations can result in a suspension from the forum, and now they have.

@rague I hope that when you return to the forum you'll be more respectful of our community.

Thanks in advance.

If you can open the door where the sensor is located you should do it.
