Hi @OlivierP ,
you can change the byte order via MultiByte Order:

@OlivierP Thanks for the feedback!

Hi Oliver,

I’m going to need more detail to be able to help?

What does your configuration look like?
What exactly is the error message and where do you see it?

How is the physical device connected and configured?

Is anything sent from the port?

Are there any further device diagnostics?

Unfortunately with all serial communications, including modbus, just one configuration error or wiring error on the master or slave will mean the communications doesn’t work. The process to solve this is really to carefully check every step.

If I was debugging your system, I would first extract as much detail on the error as possible to see if that helps.

Try answering these questions.

Does the master send a modbus request?
Is it at the right baud rate, parity etc?
Does the slave see the request?
Do it’s comms settings match?

Is the UID correct?
...

@OlivierP, what type of pH and EC sensors do you use? Would you recommend some?

Thanks in advance!

Sharing the way I solved it, feel free to comment.

Thank you again for the extensive answer!! It is clear for me (atm ;) )

Thanks David, I've got it figured out!

Thank you for the clarification, this is exactly what I did... but I must have missed something, now it works :)

I don't think it is needed to add the other channels already, seems easy enough.

Hi @OlivierP,

Is there any chance you have changed the SSCP connection username and/or password? Aside from the message "capabilities parsing failed" you should see a message containing "wrong username or password?". If so then you can fix this by replacing the image with the stock one.

If this is not the case, then it would be helpful if you could provide us with some more information, specifically the IDE version, image name and version, and the response for the command "sudo cat /proc/cpuinfo"
