Post by mabac on No file found ^{CODESYS Forge talk (Post)}
CODESYS introduced many cyber security related changes over the last few years, one of them is to restrict file access. By default, file access is restricted to the PlcLogic folder and subfolders of the CODESYS control runtime of version 3.5.19.0 and newer. For Control Win this would be the folder C:\ProgramData\CODESYS\CODESYSControlWinV3x64\xxxxxxxx\PlcLogic\ To enable access to other folders, you can configure additional paths by adding them to the file CODESYSControl.cfg. For example: [SysFile] FilePath=C:/temp/test FilePath.1=C:/Users/Public You should now be able to access your file in C:\temp\test\ or in C:\Users\Public

Post by pernockham on Images not shown in webvisu ^{CODESYS Forge talk (Post)}
Two issues. Ive been struggling to get the user management the way I want it. I want to protect the device from unauthorized upload/download, but I do not want login requirement on webvisu. The combination that seems to work is to use "runtime device user management" while keeping the visu user management in "legacy mode"? Initially this seemed to work, but now images are not loaded when using direct access, while they are still shown if I access the webpage via Automation server. Im guessing its connected to the authorization changes? Anyone able to help out? Thanks Also, I read that legacy mode should be avoided, is it possible to use "runtime based visu user management" while keeping direct access to the webpage without login. System is a "Control for linux SL, version 4.20.0.0" Per

Post by rmaas on Direct Pointers in IOMapping for EtherCAT with IoDrvEthercatLib.ETCSlave_Dia ^{CODESYS Forge talk (Post)}
Hi, Im not sure if this is what you mean, but i do succesfully use the IoDrvEthercatLib.ETCSlave.InputData and IoDrvEthercatLib.ETCSlave.OutputData to read from and write to beckhoff DI and DO cards. Very convenient as you can make an FB with an VAR_IN_OUT of type IoDrvEthercatLib.ETCSlave and only have to pass the slave reference... So i am not using .ETCSlave_Diag but .ETCSlave...

Post by nico-hefr on Python script command for "Access Control" ^{CODESYS Forge talk (Post)}
Hi everyone, I use Python Script to generate some POU in Codesys V3.5 SP19 and I would like to limit the "Access Control" to them thanks to the Python command. Is there any commands that allow to edit the "Properties... >> Access Control" of the POU? The other possibility is to set the permissions with "Project >> User Management >> Permissions... >> Project objects >> Modify >> ... >> myPOU", but I did not find the related Python commands. Otherwise, is there a global setting that allows to set the permissions by default? For example, Modify = Denied for everyone user by default. Thank you in advance for your help, Nico

in your project, to access /var/opt/codesys/PlcLogic/my.file, use the string 'my.file' or '$$PlcLogic$$/my.file'

I would expect that this is more or less Bookworm related - the GPIO access is different now - and need to be adapted
