Hi, Yes this should be possible, you should find the CodesysControl.cfg file on your plc. Open this with a text editor, and change the placeholder filepath for alarms. You can find the Placeholder filepath in the CodesysControl file under Sysfile.

Go in Windows to this location. Right click on this file and go to properties. Is it in Read-only state? Then CODESYS cannot open in Write mode.

Post by askic on Generate FBs from source ^{CODESYS Forge talk (Post)}
Hello, I'm coming from Siemens (TIA) world and currently learning Codesys. I'd like to know if there is an option to add external txt file with ST code for creation of a function block and then use this file as a source file from which FB will be generated? For example, in TIA, there is an option add external source file to the project structure and then use option "Generate blocks from source". This would create a FB. Does Codesys have something similar? This external source file would look like this: FUNCTION_BLOCK Scaling VAR_INPUT x, k, n : REAL; END_VAR VAR_OUTPUT y : REAL; END_VAR VAR END_VAR y := k*x+n; END_FUNCTION_BLOCK

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 mondinmr on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Good day, I’m writing this message out of frustration regarding the current way project files are saved as encrypted XML and single-file format in CODESYS. I find this approach to be quite tedious for several reasons: Limited Access to Structured Text: Not being able to access Structured Text (ST) externally makes it impossible to work with alternative editors like VSCode. Tools like VSCode are incredibly responsive and feature advanced systems such as GitHub Copilot, which would be a real game-changer when working with ST IEC. While CODESYS works well for small code snippets or debugging, when the codebase grows, switching to VSCode to boost productivity becomes essential, and copy-pasting between environments is a cumbersome workaround. Poor Integration with Git: This file format also makes it very difficult to integrate effectively with Git. I have tested the internal demo, but for advanced merges, it is unusable. Without properly formatted plain text, it’s impossible to leverage the vast ecosystem of external tools around Git that allow smooth merges in heterogeneous teams. File Corruption on Network Drives: I often work from multiple locations with shared network drives. When the development environment saves a file and something goes wrong midway (which can occasionally happen when using VPNs and network drives), the entire project becomes irrecoverable. There’s no way to cancel the save process, and the development environment freezes. This has happened to me at least four times over the past two weeks, and one of those incidents cost me an entire day of work. All of this is particularly disappointing because I truly believe that the libraries, runtime, and overall work done by CODESYS are exceptional. I find it fantastic that there is a platform allowing development of PLCs and control systems using OOP, which is a huge advantage in modern control engineering. I apologize for the rant, but this issue has been extremely frustrating. Best regards.

Post by mtho on JSON Utilities - JSON file written with invalid structure ^{CODESYS Forge talk (Post)}
I'm using the JSON Utilities SL library to write configurations in my program to a file. I'm generating the JSON data using the builder function block and all appears to work correctly. When I write the jsondata to file, I'm finding that some of the JSON elements are not being written in the right location in the file. Rather than writing they keys under the parent object, they get written outside the root JSON object at the end of the file. If I then try to read the file back into the program, I get an invalid_structure error. I don't get any errors when populating the JSON data or when writing the file. I attached an example of the JSON writer output. The problems begin with key P200. Each P200 should go under MBR1 through MBR3. Among the rest of the keys, they are supposed to be under different parent objects. I am using default values for wsLineBreak and encoding.

Post by psychoengineer on Cannot Save CSV File on Windows Computer Using CODESYS and Control Win ^{CODESYS Forge talk (Post)}
I am currently working on a project using CODESYS and Control Win on a Windows computer. I've encountered an issue where I am unable to save a CSV file. I have followed the standard procedures and used the appropriate file handling functions, but the file is not being created or saved as expected. IF xStartTest THEN sFileName := '\logs.txt'; sFileName := CONCAT(gvl.g_sMainDirectory, sFileName); sFileNameCopy := '\CAAFileCopy.txt'; sFileNameCopy := CONCAT(gvl.g_sMainDirectory, sFileNameCopy); //eWriteState := FILE_OPEN_TRIGGER; xTestDone := FALSE; xError := FALSE; xStartTest := FALSE; END_IF VAR_GLOBAL g_sMainDirectory : STRING := 'C:\LogFiles'; // file path for CSV file END_VAR Despite this, the file does not appear in the specified directory, and no error messages are being generated. I've checked the directory permissions and ensured that the path is correct. Has anyone else experienced a similar issue or have any suggestions on how to resolve this? Any help would be greatly appreciated. Thank you!

Post by richard-wang on Codesys recipe manager - what does it do? ^{CODESYS Forge talk (Post)}
Hi All Thanks for sharing this information. For whom may not know why always get error code 16#4000 or 16#4002 while performing Recipe commands, the root cause is There is a line need to be inserted in CODESYSControl.cfg file, which is PlaceholderFilePath.1=/var/opt/codesys/PlcLogic/ I am using Pi, therefore the above path is set to my pi unit, after adding above line to my cfg file, all the Recipe commands work fine. But I still do not know how and when this file got modified though.
