Just to close the loop that we decided to use RevPi Bookworm 64-Bit Default (01/2025) instead and the issue was resolved.

Unfortunately we haven't create the SOS report yet and we don't have the chance to reproduce it again at the moment.

Thank you Dirk for the idea about SOS report.

We used RevPi in many projects and recently encountered to a weird behavior using RevPi Bookworm 64-bit Lite (01/2025)

Hardware used are as below and both of them are configured in PiCtory correctly.
1) RevPi Core S
2) RevPi DIO

When check with piTest -d, expecting to see only 2 devices but it ...

We want to use touch screen with RevPi.

Reading around seems like kunbus recommended Faytech brand.

Can you help confirm if below model can use touch screen mode with RevPi?

We have successfully created the image of RevPi Core 3 and this image worked well when flash to another RevPi Core 3.

But when we flash this image to RevPi Core 3+ 16GB, the screen got stuck at rainbow splash and couldn't continue.

Anyone know what is the root cause and how to resolve?

Thank you.

Hi Dirk - Thanks for the prompt and clear answer.

RevPi AIO is equipped with 24-bit ADC, while RevPi Compact is with 22-bit ADC.

Why do you guys decide not to enable the raw data reading on RevPi AIO?

The value read from RevPi AIO is like truncated down to lower resolution then.

Hope the team ...

We have a new project that requires analog input reading for 1 digit of precision under millivolt unit e.g. 1.2 mV, 3.6 mV and so on.

Total analog input channels required is 40 channels for a set so 10 units RevPi AIO modules will be perfect in terms of number of channel.

Configuring the input ...

Thank you Amar, that is exactly correct and make it worked!

One important thing is that when the QTY is not 1 then the rest will be automatically allocated to the next available variable name.

Taking below quote from this tutorial - https://revolution.kunbus.com/tutorials/modbus/revpi-core ...

It is confusing with the term "Quantity of Registers" in PiCtory since changing from 1 to other value has no different.

While the only option is to read from adjacent Register Address and then perform some calculation on your own, with this, maximum Quantity of Registers that RevPi can read from ...

Anyone from KUNBUS can help test this with CODESYS?

We don't have any experience with CODESYS so we need help from your team to clarify.

We are configuring PiCtory in RevPi Connect to communicate with MODBUS RTU Slave device and have a question below.

1) We need to send below message -> How to set the Extended Data in PiCtory correctly?
