Just open a codesys 2.3 project in codesys 3.5, then the converter starts.

Hello,

When I'm opening a Codesys 2.3 library with Codesys 3.5, I do see some conversion taking place.

Including the converted library into a 3.5 project does compile. But when trying to load it into a PLC, I get "Unresolved references"

Any ideas where these come from?

I also noticed in the converted library project, the POU tree shows (FB)(EXT) behind the POU name.
In the 2.3 version of the project, (FB) is shown.

What's the reason behind this (EXT)?

Thanks in Advance

In the help files installed by the IDE can guide you through the steps.
Converting a library can be tedeious and time prone.
Also beware, there is no real guarantee that conversion will succeed, and there are several ways to do it!

Found the culprit of the "(EXT)".
When saving the 2.3 project, I saved it as an "external" library. That meant I had to implement en compile the interface outside of Codesys, (for example in C).
Saving the library as "internal" fixed it for me.
Codesys 3.5 was able to convert it without any issues. :D

As you have already discovered, the x64 version of the CODESYS v3 IDE does not support the conversion tool.
A possible but a bit crude workaround is to install both x64 and x86 IDE's in tandem.

Hello,
I have a problem openening the older (2.3) libs.
There should be an option 'Codesys library files(before V3.0)' in the filetype selection box in the 'open project' window.
I friend of mine has it, but I don't.
I use version 3.5.14 patch 2 64bit and as you mentioned before, it should only be possible in the 32bit version.
So I installed version 3.5.15 patch 2 32bit in tandem, but the option does not appear in this version too.

What can I do to fix this problem?

Only works if you have already installed the plugin called CODESYS V2.3 Converter.
