Post by snhatton on Retain memory change to ZERO ^{CODESYS Forge talk (Post)}
I think more information is needed to help solve the issue. Can you list the exact steps to reproduce the issue? What version of Codesys are you using? Did you add a persistentVars object to your project? I would recommend browsing all instances of the retain variable to see all possible writes to the variable in question.

Hi, for Control Win : add CmpEL6751CanDrv in the c:\ProgramData\CODESYS\CODESYSControlWinV3x64\E1FA7ABE\CODESYSControl.cfg [ComponentManager] Component.1=CmpTargetVisuStub Component.2=CmpWebServer Component.3=CmpWebServerHandlerV3 Component.4=SysCpuMultiCore Component.5=SysReadWriteLock Component.6=SysCpuBreakpoints Component.7=SysPipeWindows Component.8=CmpEL6751CanDrv for Linux SL or Pi or any ARM device - I think it is already static loaded as component - see plclogger on startup

Thanks for your response! It seems like the VisuElems library has updated functions to the ones you used but apparently these older ones still work, even if I couldn't find them in the library documentation and they are also not suggested automatically by Codesys (when using Ctrl + Space). However, its precisely what I was looking for and it works. Thanks!

Hi, Got same problem, appeared after 4.3.1.0 update. Prabably problem is in performance. I am using virtual machine, so adding one more core and several GB to RAM still not solved, but atleast did system more stable. Try optimise your main program or set less task interval. Regards, I will be your mate in solving this mistery =)

Post by totorovic on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"
