Re: RevPi Connect

The device has a HW watchdog,which (when enabled) needs to be served every minute by toggeling a bit in the Process image. If you do not do so the device does a cold start (power cycle). So please check if you have disabled the WD by putting a wire bridge between "WD" pin and "GND&quo...

Re: Best practice for developing python scripts for the RevPi?

Hi, I've personally always used the x-windows desktop with the python shell when writing python scripts for a RevPi. Mostly this is due to the complex IO which would be difficult to simulate. When I do not have local access with HDMI Monitor and USB keyboard/mouse I do use realVNC which is part of o...

Re: Updaterequest: Virtual01_20160818_1_0.rap

Danke Sven. Das macht sicher Sinn, mal mit aufzunehmen. Dauerhaft ist aber die einzig gute Lösung ein RAP-Editor, bei dem die Typen vom User verändert werden können. Wir sind dran und mal sehen, wann das Teil verfügbar sein wird...

RevPi + Codesys = high performance PLC?

Ein User hat per Email folgende Frage gestellt: Ich würde ausschließlich den RevPi Connect [mit Codesys] als Steuerung verwenden und über die LAN-Schnittstelle (über EtherCat) einen Beckhoff Buskoppler mit Beckhoff IO Modulen verwenden (also keine Kunbus Erweiterungsmodule). Also das bedeutet doch, ...

Re: System Watchdog

Basically, no. This is a piece of hardware in our RevPi Connect which cannot be replaced by software. In a RevPi Core there is a way to somehow monitor your sw and react by kernel driver switching the outputs to off when the application is no longer writing data to the PI ( see here: https://revolut...

Re: Watchdog for digital outputs

It is just as Sven said: This is not an application WD. The Application WD is built in piControl which can monitor a PLC software like logi.cals. It does measure the last cycle time and if this last cycle time has run out without another write access to piControl it sets the outputs of DIo or DO to ...

Re: Management tools for a lot of RevPi Core 3

KUNBUS does not have tool yet for deployment tasks. We do offer customization (e.g. custom specific images on delivery) but it seems you're looking for tools after delivery. You could go for cloud services like AWS greengras , Azure, etc. which do allow for mass deployment of system updates etc. Ple...

Re: System start on reboot sometimes fails

This sounds somehow weird and we never ever experienced such a behaviour. Can you definitly elimiate that this is caused by your network? Are you running on DHCP? If you experience such a failed boot could you try recovering the services by unplugging and replugging the Ethernet connection? Could yo...

Re: Einfache GUI für Python

RevPiPyLoad ist Bestandteil von RevPiModIO, bitte daher in dem zugehörigen Forum (Maker's corner) dort die Frage stellen. "virtuelle Module" sind in PiCtory wie "reale Module" anzuordnende Module, die aber physikalisch nicht im modularen Aufbau zu finden sind, weil es sich um rei...
