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

Thank you wollview, it is clear now, it is due to security reasons that access to the file system is restricted.

Post by sbhaskarla on WebVisu File Transfer Error ^{CODESYS Forge talk (Post)}
I’m encountering an issue when downloading CSV files via the WebVisu button input config -> file-transfer option: • Custom directory: /plcdata/csv_logs/filename.csv o Error: Error 4 – Error during file transfer • Sandbox directory: /var/opt/codesys/PlcLogic/plcdata/csv_logs/filename.csv o Result: Download succeeds without error. Actions taken so far: 1. Added /plcdata/csv_logs to codesyscontrol.cfg (see attached). 2. Enabled file-transfer services in codesyscontrol_user.cfg (see attached). 3. Confirmed that the PLC writes CSV files correctly to /plcdata/csv_logs/. Despite these settings, WebVisu still returns Error when accessing the custom path 1. Using the placeholder file path '$$CSVLOGS$$/filename.csv' and it returns Error 6. 2. Using the literal path /plcdata/csv_logs/filename.csv and it returns Error 4 Could someone please help me determine what additional configuration or troubleshooting steps are required to serve files from /plcdata/csv_logs/? Please find screenshots attached for better understanding and I have also attached the config files

Post by cellohorst on File Creation Issue ^{CODESYS Forge talk (Post)}
Nope! The file path is $$PlcLogic$$ and NOT $$PLCLogic$$. Otherwise a new folder ('PLCLogic') is created (at least with a linux rt - like raspberry or compute module) with the new file in it if you open the file with eFileMode := FILE.MODE.MRDWR. That is a bad bug that I'll report right after this comment.

Post by syjoo on Recipe Manager in PRG (3.05.13.XX) ^{CODESYS Forge talk (Post)}
I'm using version 3.5.13. Is it possible to handle Recipe Manager in PRG in this environment? Can you give me a simple example? Although it has been confirmed that the functions work on Recipe Manager, they do not work properly when implemented through FB within a simple PRG. I would like to save the current value as a recipe or load the recipe's value as the current value. And I want to save the recipe as a file or load the recipe saved as a file. somebody help me. (TT)

Post by jami on Reading multiple lines from csv file ^{CODESYS Forge talk (Post)}
Hello, i am trying to read multiple lines from csv file with caa file library and oscat. I have wrote 7 lines in the csv with separation '$R$L'. In my "extracting values" part I check line feeds and chars. After that I convert my buffer to string with oscat but I'm only able to read the first line from the csv. No matter if I even change start position where I start converting the buffer, I only get the first line. Here's my code for the reading and extracting value parts: 4: (*Reading the file*) fileread.hFile := filehandle; fileread.pBuffer := ADR(buffer); filesize1:=SIZEOF (buffer); fileread.szbuffer:=filesize1; fileread.udiTimeOut := 100000; fileread(xExecute := TRUE); IF fileRead.xDone THEN iFilesize:=TO_INT(fileread.szSize); writestate:=3; fileRead.xExecute := FALSE; END_IF 5: (*Extracting values*) //here i check the number of line feeds and chars. It works WHILE i < ifilesize DO c:=buffer[i]; IF c= 10 THEN IF lineindex<=99 THEN lineIndex := lineIndex + 1; END_IF ELSIF c <> 13 THEN IF charIndex <= 1000 THEN charIndex := charIndex + 1; END_IF END_IF i := i + 1; END_WHILE // Here i convert the buffer to string and transfer it to filelines:ARRAY[0..99] of string[254]. trig(CLK:=BUTTON); IF trig.Q THEN fileLines[i2]:=oscat_basic.BUFFER_TO_STRING(PT:=ADR(buffer), Size:=TO_UINT(fileread.szBuffer), start:=TO_UINT(bufferStart), stop:=TO_UINT(filesize1)); i2:=i2+1; bufferstart:=bufferstart+80; END_IF If anyone has idea how to read multiple lines, it would be nice. Even if you have example codes that work, that would help a lot.
