e!Cockpit program: TP600 screen freezes up when opening a webvisu page

@ChrisB and myself are having an issue where we if we tap a button to open a new page that hosts a webvisu, then the TP600 screen locks up for several minutes ( it freezes on the HMIs main screen, after tapping the button to open the webvisu page.)

We’ve double checked the URL and that seems correct, but I suspect we don’t have a setting correct. Any ideas or obvious settings we are missing? Anything we need to enable on the HMI’s webpage?

HMI is a TP600 7" PIO3. I’m not sure they are helpful to anyone here, but the webvisu element’s properties are in the screenshot below. Let me or @ChrisB know if you need anymore info.

Hi,Which fw is in use?

Have you been able to check the log messages yet?

Either via e! C View → Device messages or the file /var/log/runtime.log
you are using the TargetVisu, right?

It looks like we are using firmware 22 on the PFC200 Gen 2 (750-8216) that is hosting the webvisu and version 22 on the TP600 (762-5303) trying to view the webvisu.

On the TP600, we have a display with a Web Browser element pointing to the PFC200 (see the screenshot Kevin posted). Also on this page is a text box and a button to return to a home screen.

On the home screen (TP600), there is a button to navigate to another screen with the Web Browser element. As soon as you press the button on the home screen to change screens, it (TP600) becomes unresponsive (on its own display, but e!C and the WBM are still responsive). We aren’t sure why it locks up, and I’ve only been able to get it to recover by rebooting the TP600.

From my laptop, I can navigate to the webvisu being hosted by the PFC 200, so I know that it is working.

I have not tried to look at the logs. TBH, I didn’t know they existed. I’ll try to remember and look at logs next time I’m logged in.

Hello ChrisB,
Hello KevinPNNL,

unfortunately there is a BUG in CODESYS from version 3.5.17.30 to 3.5.19.20.
Usually the following message appears in the device message when using the Web Browser element in TargetVisu.:

The behaviour is solved with CODESYS version 3.5.19.30 and is listed at CODESYS under CDS-86697.
If you want to continue working with e!COCKPIT, you need a firmware that has a compiler version 3.5.16.32 or lower, for example FW 03.09.04(21).
Alternatively, you can also use the FW 04.05.10(27) (CODESYS 3.5.19.70) .
Another alternative would be to display the Web Browser element only in the WebVisu.
You can use the following workaround for this:
