Hi,
I done my HMI+PLC apllication on RPi using - ComfilePi - Industrial Raspberry Pi Panel PC.

It possible that this soultion provide work stability on web browser ?
http://comfilewiki.co.kr/en/doku.php?id=comfilepi:codesys:codesys7

I run my application. Works perfectly for several hours, but next day my browser page is suspended. the reason can be is the browser? what do you guys think?

maybe, check the plclogger for more information.Is it possible to open on another browser, device if this device/browser is suspended?

I do not see any errors. It is possible to export logger ? In attachments I send three screen but without errors...
On another browswer I will check next time.

So far, 12h works without a problem ... We are still waiting

Do you know any PLC working with Codesys with two or more RS232 - where all ports are programmed by SysCom form Codresys ?

Looks like after a few days of work in the browser in RPi there is a lack of resources, because:
-from codesys I can login
-I can't login to Pi by SSH
Probably problem with web browser cache.

Oryginally I run my app by command:
@chromium-browser --kiosk --start-fullscreen http://localhost:8080/webvisu.htm

Now I try run in incognito mode, with command:
@chromium-browser --kiosk --start-fullscreen --private-window --app=http://localhost:8080/webvisu.htm

@eschwellinger - Can you think that can be solution form my problem ?

Others reported the same problem on chromium browser - but I have no feedback on the final solution.

Now I tests firefox-esr.
I should run kiosk mode in this way on firefox:
@firefox -kiosk -private-window http://localhost:8080/webvisu.htm
OR
@firefox -kiosk -private-window http://localhost:8080/webvisu.htm &

?

@damian177 is there already any news on your tests? We have a similar issue with the visualisation quiting after x days/time. I have not tried firefox yet but i am running the chromium in icognito already and that didnt seem to help.

I was using firefox-esr but worked much worse. I came back to chromium browser:

@chromium-browser --kiosk --start-fullscreen --incognito --disk-cache-size=1 --app=http://localhost:8080/webvisu.htm

In my application on this webbrowser the memory rise about 4% around the clock. So I restarting webbrowser everyday on midnight (takes up to about 5 seconds). To this function I use script:

1
2
3

#!/bin/bash
pkill -o chromium
chromium-browser --kiosk --start-fullscreen --incognito --disk-cache-size=1 --app=http://localhost:8080/webvisu.htm

powered by crontab:

0  0    * * *   pi      DISPLAY=:0 /bin/sh /home/pi/kiosk.sh

I was investigating high memory usage of chromium when running the CODESYS Webvisu.
I was able to reproduce the memory increase without the CODESYS Webvisu as well and reported this observation to the panel OEM.

Right now I can just recommend restarting the browser every x hours until the bug in chromium is fixed.

Best regards,
Marcel
