Hello Incorrect password. Please provide me with a correct password.
password: plc247.com
Whoever is having issues with the incorrect password, make sure you’re actually downloading the CodeSys and not SysmacStudio. There is an issue with the download link, if you hover your mouse over it, you’ll see that there are three different underlines, depending on whichever one you click on, it might take you to GDrive download for either CodeSys or SysmacStudio. Just make sure you’re downloading the right thing, as the password only works for CodeSys. Hope this will be helpful to any you folks having issues!
thanks sir
