Post by keith on Ethernet Adapter issues ^{CODESYS Forge talk (Post)}
I uploaded this project and it was running. After upload I had to re-download to get the system to sync up. I now have this fault and am not sure how to resolve it.

you have visited https://en.estun.com/?list_139/1380.html and registered and there are no ESI files at data download? Asked the manufacturer?

Yes, that's correct. I registered and visited the page at https://en.estun.com/?list_139/1380.html , but there were no ESI files available under the Data Download section. I also tried contacting the manufacturer directly, but haven’t received any response yet.

Post by rabaggett on CODESYS control for Raspberry Pi 64 SL errors ^{CODESYS Forge talk (Post)}
Update: I started over. I saved progress at each step. all compiled zero errors, zero warnings. Pre-processor messages remain, but I can make progress. Until I try to re- load the project file in Codesys. Re-loaded files error as above when compiled, even though they compiled error-free immediately before saving. Is my installation borked? (Not easy to re-install due to IT madness...)

Post by hismoon on CodeSys SVN funktionert nicht ^{CODESYS Forge talk (Post)}
Das CODESYS SVN AddOn hat Minimal-Versions-Vorgaben. In SP9 funktioniert wohl die neueste SVN Version nicht. Da mal am besten im Store auf die Release Notes auf der Download-Seite schauen. Da steht meistens, ab wann Minimal-Versionen erhöht wurden. (Required CODESYS version) V4.2.6.0 vom SVN AddOn scheint die letzte zu sein, die mit SP9 offiziell funktioniert. Eigentlich sollte das der CODESYS Installer / Package Manager abfangen, aber hmm.

Hey, I am facing the same problem. Basically UA Expert and other programs work fine with the login credentials. But codesys can not use them properly. I can see the server login to it manually but when I download the program and run the datasource never runs... Currently I am facing the same Error ID: 7012 and cant get it running properly.

Post by jeroenaero on CodeSys Raspberry pi I2C driver not found ^{CODESYS Forge talk (Post)}
okay, the weird thing is the driver is only continuous running when i enable debug output. if debug is not enabled it's continuous switching from running to not running. i will check again and download the libraries Which versions of libraries do you use, can you send a screenshot?

Post by matthew on Persistence Manager Backup ^{CODESYS Forge talk (Post)}
Hi @eschwellinger yes I have been using xDoubleStorage It happened again and I checked and the files were still there with there contents, restarting codesys or rebooting would not even reload them. Doing a download and then starting the PLC loaded them and began working again. Some sort of mismatch error or something?
