how can i get the data from atlas copco compressor using arduino ?

Perhaps you should define what data you are looking for.

I can think of two:

  1. current (or power)
  2. Pressure

Each would require some sort of transducer.

If my memory is correct that is an air compressor. Getting data is easy, put a thermometer on the air outlet and you will know its current temperature. At this point I do not have a clue as to what you want.

Free Project Design: Interesting project but we are not a free design service. We will help out with your code but first you have to make an attempt to write it, post it and explain what is not working properly. Also do the same with the hardware it is always best to post links to technical information as there are many versions of the same or different items. Since we cannot see your project, my eyes are to weak, you need to post an annotated schematic (best) or a clear picture of a drawing. Pictures never hurt. Frizzing diagrams are not considered schematics here.

Specifically which model and are you using their controller board?

IS this a screw compressor or a piston type compressor? Do you have the service manuals for the compressor?

Depending how old your unit is… Usually done through Modbus-RTU sometimes the Modbus is bridged through proprietary “smartNet” or “linkNet” garbage of some sort…

even then, good luck getting the Modbus registers from them. Copco is the perfect example of an empire failing in my opinion… at least in the mining industry up here in northern Canada, support after a sale in nearly non existent.

Some part numbers / model numbers may help people help you

i wan't to know how much time the compressor worked just the time, i want to communicate with the PLC or something like that

unfortunately i don't have much infos but i know that the compressor use an air pump to press the air

thank you i'll work on that

Tell us why you think you can get data from that compressor?

You could:

  1. Sense the current draw of the motor. Simple current transformer and a diode and maybe a resistor or two.
  2. If there is a rotating part you can "see", you could put a white line on the part (pulley etc). Then use a reflective sensor.
  3. You might be able to sense vibration with an accelerometer.

There are likely other approaches, however these came to mind.
