Re: Modbus isolation

Dear Anil, could you please explain what you mean by "Modbus isolation"? So this is just a low cost but pretty well functional RS485-USB converter. It transfers logical signals. Modbus is one layer on top. Therefore it does not deal with Modbus.

Re: Messabweichungen beim AIO Modul

Hallo tucan, das klingt seltsam. Das AIO Modul kann maximal einen Strom von 24mA treiben. Wie kann dann eine Abweichung von 500-700 mA entstehen. Ich habe folgende Ideen für Dich: Der maximale Strom ist bis 600 Ohm möglich, die maximale Spannung ist bis 1 kOhm möglich. Siehe Datenblatt . Das AIO Mod...

Re: RevPi Core 3 *.img to RevPi Connect+

Hi David_GT, short answer: Yes, you can switch from i.e. Core 3 to Connect. The easiest way is to delete the file "/home/pi/.revpi-factory-reset" before you write the image. Then you are promptet on first login to provide Serial, MAC and which device. After a reboot you are ready to run. This is wha...

Re: Avoid eMMC corruption without UPS

Hi Antoine, well sure a UPS is able to provide a safe way to reboot the device properly. I just can say hat we deal here with may devices every day.

Re: Unable to create Img

Hi Sean, well it is unlikely that we have sent you a device with a hardware error as the end test uses the micro USB connection to flash the devices. But in the end I just can ask you to use other USB hosts i.e. laptops, etc. and try it again. There are unfortunately always users that run into such ...

Re: DIO Input/Output Überlappung

Hallo Max, nein diese Verbindungen zw. Ein- und Ausgängen existieren nicht im DIO Modul. Die Idee war hier wohl, einen Schaltplan zu machen für alle Module und dann gibt es sicherlich Varianten in der Bestückung ;-) Hier die Übersicht Modul / Eingänge / Ausgänge DIO / 14 / 14 DI / 16 / 0 DO / 0 / 16

Re: RevPi Connect recompiled kernel error with piControl

Dear Roberto, this may be the point where the device tree is missing something here. Have a look at the "revpi-factory-reset" tool. You have to configure the device tree according to your device, i.e. RevPi Core, RevPi Connect, etc.
