Hi znetsixe, one possibility is to take a look at the circuit diagrams available in the download area. Please note that this will invalidate any warranty claims.

Hallo FGCan,
hier ist in der Tat ein Feature nicht implementiert. Ich habe das ganze mit einem Testaufbau untersucht und intern besprochen. Entprell-Feature ist in den Modulen RevPi DIO/DI/DO zwar implementiert jedoch nicht im RevPi MIO Modul.

Hello daniel_123, there may be an electrical problem. Can you visualize the signals with an oscilloscope?

Hello daniel_123 my friend, so i have performed a test setup without a function generator.

I used this signal diagram as a template

I used a DIO and wired it like this

Output Channel 1 -> Input Channel 1
Output Channel 2 -> Input Channel 2

I have set PiCtory like this ...

Hello bg rania so I've just made a test setup using the latest RevPi OS Bookworm (250124-revpi-bookworm-arm64-default.img) and a RevPi Compact. So that's what I got. I am still at a loss as to whether a change has been made here or whether the "EERAM Susbsystem" works differently due to the large ...

Hallo Andreas, klasse vielen Dank für deine wichtige Arbeit, das wird helfen, unsere Dokumentation hier zu aktualisieren.

Hello daniel_123, can you check the wiring? It may be a ground wire that is causing the whole timig to go out of sync. Do you have the possibility to look at the signals with an oscilloscope?

Edit: I can try to create a test setup. However, as a function generator is then required as an external ...

Hello aladanh2000, thank you for your detailed report. Unfortunately, I was unable to reproduce the problem with a test setup. However, it occurs with the PCP plug-in for Cockpit. Therefore, please contact Upstream with this report as this is outside our responsibility. Thank you

Ja, erst abschalten, dann Hardwarekomponenten wechseln, dann einschalten und voilà.

Edit: Es ist zwar etwas weit hergeholt, jedoch kann es sein, dass die Firmware-Versionen der Module unterschiedlich sein können. Du kannst mit "piTest -d" die aktuelle Modulkonfiguration inklusive der Firmware ...

Hello ninad110, my friend, I would divide the problem into 2 parts:

1. bring RS 485 Modbus communication to the sensor into the process image:
You can do this with the videos and tutorials available here:
