Thank you for the wonderfull answer Martin!

Currently the RaspberryPi only has the SD card as memory space indeed, but it would be possible to attach an external drive.
After creating the Modbus Server Channel, I was instantly able to view all the values that I wanted. Now I can experiment with how we want to store our data.

But first we're going to see if we can attach it to the internet so we can use the MervisDB.

Thanks for the info!

Ah, that's the same one as we have. If you want to be able to connect through SSH you can use the UniPian Image. But then you won't be able to use the Mervis IDE as far as I know

No problem, just sharing my limited knowledge :).
What device are you using? A regular UniPi, a Neuron, ...?

How exactly do you want to log in to the MervisOS?
And the default is admin:rw for Mervis

Hello,

I was wondering how I can access the data on my Neuron M203. It's running on the latest version of Mervis.
We have a very simple setup:

• The Neuron M203, which hosts a web panel

• A Raspbery Pi with raspbian connected directly to the Neuron with an ethernet cable. We use this one to display the webpanel.

Both devices are not connected to the internet.
We want to store a few parameters of the PLC in an InfluxDB on our regular Raspberry Pi. How can we get the data from the PLC? I've seen a few things about TCP/Modbus, but I have never used Modbus before. So I'd need some extra help with that.

Thanks in advance,

Steven
