Post by jmohre on External file with relative path ^{CODESYS Forge talk (Post)}
I try to add a simple text file to my PLC application, so that is download everytime the application is downloaded to the target. What I did is to add an external file to the application and this works perfect as long as the external file location does not change. It looks like the external file path is stored absolute in project. But if different users work on the project they may have different locations where for their working directory. Is there an option to store the external file path relative e.g. to the project file? Or does s.o. know a different solution to add a text file to application in order to download automatically with the application? Thanks

Post by canplum on Codesys 3.5.21 fails to copy file to USB ^{CODESYS Forge talk (Post)}
Although I have set in /etc/codesyscontrol/CODESYSControl_User.cfg the [SysFile] PlaceholderFilePath.1=/media/pi, $usb$ PlaceholderFilePath.1.View=1 PlaceholderFilePath.1.Volatile=1 I am not able to copy a file to this directory defined by the placeholder. Neither SysProcess.SysProcessExecuteCommand2 nor SysFileCopy nor FileCopy is working. If I try to copy the same file to /home/pi all is working fine. I also can create and open a different file by using SysFileOpen. I don't understand why the system allows to open (create) and write files into that directory but doesn't allow to copy into it. Obviously there is a rights problem with the USB drive. I have already set the permissions to drwxr-xr-x 2 and the user to pi but without any success. With 3.5.16 I never had such an issue. Is there anybody with some hints how to solve that problem? Cheers, canplum

Post by gatto on CAA File open Problems ^{CODESYS Forge talk (Post)}
Ciao, here same question https://forge.codesys.com/forge/talk/Engineering/thread/2538729618/ in this post https://forge.codesys.com/forge/talk/Engineering/thread/4586a90290/?limit=25#d531 i find : keep in mind that all files which are generated / or read should be exist in the iecfilepath this means: for Windows (Control Win as example) c:\ProgramData\CODESYS\CODESYSControlWinV3x64\268E8ADF\PlcLogic for Linux /var/opt/codesys/PlcLogic I never use codesys on windows but im sure on linux we can manipulate file only inside /var/opt/codesys/Plc Logic. Or you need to modify the file codesyscontrol.cfg for change path permission, but this is another history Buone feste !

Hi, How can you access the <root> of the Linux system? I'm struggling with this as the code above results in an invalid handle, as it cannot access '/'.</root> I am using Control for Raspberry Pi for context. Thanks.

Post by timvh on Access Violation sherd memory ^{CODESYS Forge talk (Post)}
Maybe it is better to use Interfaces to access the objects instead of pointers. But besides that, is "read_obj_ptr" a method? If yes, you need to call it, so add brackets behind the method call: read_obj_ptr();

Post by pernockham on Control for linux SL, 4.14.0.0 -> 4.15.0.0 breaks web page access. URL requires authentication ^{CODESYS Forge talk (Post)}
I have a problem which I have identified with a device-update from 4.14.0.0 to (4.15.0.0-4.17.0.0) where the newer versions will stop any local access to the internal web page with the browser responding "The requested URL requires authentication". Setting the device back to 4.14.0.0. the web page will respond. Access to web page through Automation server is possible also for the newer version, but not "local" access. Runtime (Codesys control for linux SL) is on 4.17.0.0. I have tried to manipulate settings for 'Access-Control-Allow-Origin' '*' always; through nginx (normally a proxy_pass to localhost:8080). Also tested bypassing nginx by accessing 8080 directly with the same result.

Post by wbj0t on Global variable access by Programms and Modbus Devices (attach device to bus) ^{CODESYS Forge talk (Post)}
Hi everyone. I use Raspberry Pi 4, one core codesys SL. I have a question about global variable access via programm when I glued the same variable to MODBUS SERIAL/TCP DEVICE holding register. So, the question: what behavior of this modifying? When I set "Always update variables (in bus cycle)" and set some task as bus for the Device, then in another task I cant change this varible (can, but immediatly the old value setted again). But the same things works with MODBUS SLAVE: again "Always update..." and master attached to some task, then I change variable in another task and all works. I cant set up my variables from retains file at PrepareStart event because of this behavior with MODBUS SERIAL/TCP DEVICE. Thanks, wbj0t.
