Post by kut69 on Retain / Persistent Variables in Codesys for Raspberry Pi ^{CODESYS Forge talk (Post)}
Hi, I am interested in details about the .ret file in the filesystem. I have already a project where the file is used (write on demand, read by start) and I want to share it as 'default input' for test devices using the identical application. Opening the .ret file content in a hex editor (I only use a single string retain var) I asked myself what the meaning of the first 24 bytes is. It neither contains a handle to the application nor a reference to the variable. Is this maybe a timestamp? Or a CRC/checksum? Regards, Thomas

Post by mgengler on Recipe Manager - Not Creating Recipe Files ^{CODESYS Forge talk (Post)}
Recipe Manager will load windows explorer view and allow file name to be typed in or existing file selected but will not create a new file or overwrite an existing. Will not create a file in the default folder or even a defined folder like "c:\recipes\" although it does properly navigate to that folder location. I made sure the folder is not read-only. Can't figure out what is missing...

After a project is opened and I have done some changes, I want to start the build or code generating process by a python script file. After the build is done I a Windows sound/beep should appear. Anyone has an example or hint how the .py file has to look like? Thanks!
