Hello,

I was unable to find the device (RevPI core S ) with the mentioned Codesys verison 3.17, so we isntalled 3.19 and now we can see it.
Now we faced this probem - what can be the reason ?

Hello ivan.chonin@axbul.bg,

I think the error occurs because you have connected more than 5 devices to a single PiBridge.
You can connect 5 devices on each side.

Hello,

We solved the issue after we followed the codesys checklist.
https://kunbus-gmbh.atlassian.net/servi ... 2687893508
The problem was the new version of Codesys development system

HEllo,
The problem is back again. We followed your advice to put 5 devices on each side but we got the same error.
Please advice.

Hello ivan.chonin@axbul.bg,

It appears that you might not have configured the PlaceholderFilePath for "pictory" in the file /etc/CODESYSControl_User.cfg. In this case, no config.rsc is being created. Please check your configuration and make sure the PlaceholderFilePath is correctly set to resolve the issue.

have a look at the forum entry below:

So this file is created every time when we change something from the configuration ?
It looks like this file /etc/CODESYSControl_User.cfg is created by some script every time when we change something on the configuration of the modules
It seems every time when we change the cofiguration - we must add these 2 lines to the file.
After we add these lines again - it says it is OK

Hello,

Same problem but this time with new device...
One of our old devices start asking for username and password again and again after we try to log in to CODESYS.
We solved the probem by installing the newest version 4.8.0.0
Then I was able to log in but we see the same problem with missing drivers and red triangles. I add the 2 lines

[SysFile]
PlaceholderFilePath.1=/etc/revpi, $configrsc$

to the file but even after restart of th edevice I still see the same problem.
Please Help!
