Post by dkugler on Codesys SVN CODESYS Forge talk (Post)
Don't set on SVN. The service phase has started in March 2024 and will be discontinued in 2027. We actually use SVN and have to switch to GIT in the future. As I informed, there is no way of getting a single SVN or GIT licence. I' dont understand, why Codesys forces us customers to pay for an expensive Professional Edition paket from year to year using only one part of it! If you find a way to buy a single licence, let me know.

Post by fdmartello on Unable to compare projects containing alarm manager 4.5.0.0 CODESYS Forge talk (Post)
Hello. In Codesys version 3.5.19.50 when comparing two projects that have an "Alarm Configuration" obj from the Alarm Manager library vers. 4.5.0.0 the attached error pops up. This originally happened with two projects that I converted from vers. 3.5.17.30 so, thinking it was some conversion issue, I created two clean projects directly in 3.5.19.50 using the Standard Project template and only added the Alarm Configuration objects in them. The result is the same and the only way I found that allowed me to compare them is by deleting the incriminated object in one of the two projects. Has anyone else encountered this issue? Best regards
