My filtering stopped working when just upgrading to version 2.5.3.
See the following structure in my CODESYS application and the result in Factory I/O:
The same settings worked before.
If it’s unclear, I only want to get the global tags created in ProdLine.

Hi @johan.lundberg,
This is a regression from 2.5.2. We will release a hotfix for it shortly. In the meantime, I recommend that you [downgrade to 2.5.2](https://factoryio.com/download-archive). I apologize for the inconvenience.

Ah, fast fix which is great!
Luckily I was able to continue with old tags but now I can finally import additional.
Thanks!

Hello Bruno and Johan,
I have the version 2.5.4 using with Codesys 3.5.15
First 2 projects works fine using step by step of the tutorial.
But now not work more. The image show the problem.
Any idea?

Hi @apaixonados.mecatron,
Some ideas:
- Check that you are connected to the correct OPC Server. It should be displayed in Factory I/O as OPCUAServer@xxxx (UA), where xxxx is your computer name.
- In Codesys: check that your global variables are declared in a Global Variable List called FIO
- Check that Codesys Control Win V3 is running
- Check that you have downloaded your Codesys project to Control Win V3
- If you are using a trial version of Codesys, check that you haven’t reached the trial time limit.

Thanks for the response.
At Codesys the Gateway from time to time cant find the virtual PLC.
I use Codesys V3.15 SP15.
What version of Codesys do you recommend it to be used with Factory IO?
Thanks in advance.

@apaixonados.mecatron,
SP15 should work just fine. Keep in mind that the demo version of Codesys Control Win (virtual PLC) only works for 2 hours. You will have to restart it afterward.
