Variable >16bits
Hi, How do I declare a variable that is larger than 16 bits? If I attempt to read more than one register Pictory starts overwriting the following variables. Therefore, I need to create something like Variable_1, Variable_2 and read them out separately and merge them in my application to keep working...

Re: revPI health status
Hi Guiseppe, How exactly does that relate to my question? Assuming you are referring to the health-status webpage at the very bottom of your link, that one only gives me some high-level information I can easily obtain via top/htop. I am interested in the wear-level of the EEPROM, or am I missing som...

Re: Single-Time Write via Modbus
Hi Nicolai,
Have you considered implementing such a single-time write feature for the new release?
Cheers,
Nils

revPI health status
Dear community, Is there a preferred way to get health statistics on a revPI Connect+ 32GB? I am especially interested in the EEPROM status / its wear level on the compute module since I am running a small database on the revPI itself, which has quite some write actions. I´ve tried smartctl, but tha...

Re: M2 Slot
Hi Nicolai, wir nutzen aktuell den RevPI Connect+ 32GB, da er mit der onboard RS485 Schnittstelle ohne extra-Gateway mit Modbus Geräten kommunizieren kann. Der Anwendungsfall ist der Betrieb einer Datenbank des Anwendungsprogramms welches auf dem revPI zur Steuerung läuft. Die erhobenen Sensorwerte ...

M2 Slot
Hallo, falls noch nicht auf der Roadmap für den RevPI4 würde ich gerne anregen einen M2-Slot mit auf der Platine einzuplanen. Die bisher maximal 32GB auf dem CM4 reichen bei manchen Applikationen nicht aus. Ein USB Anschluss einer externen SSD ist nicht sehr robust. Ich verweise auch auf folgendes P...

Re: ModBus service is not starting correctly after revPI reboot
Hi Thorsten, du kannst den Modbus Service immer nach einem Restart des Treibers mit "systemctl restart pimodbus-master.service" ebenfalls neustarten. Ein Neustart des PI ist nicht nötig. Der Befehl muss mit root Privilegien ausgeführt werden. Danach sollte die Modbus Kommunikation mit den ...

Re: Single-Time Write via Modbus
Hi Nicolai, I tried and it leads to many errors during the communication. There can only be one Modbus RTU master on a serial bus at a time. Therefore, the problem remains. I will have to disable Modbus service / manually send RTU command / enable Modbus service which is not very elegant and might l...
