Hi!

Im a newbe on both codesys and Linux, is there any function for Reading/Writing files to the memorycard?

I want to use the card for config-files and logging.

Hi Urban,

the steps are:

download the file utilities example from the store.
Then as usually the procedure is open it from

"c:\Users\<your user="" name="">\CODESYS Examples\File Utilities\FileUtilities.project" </your>

rightclick on the plc device and update the plc to raspberry pi device.. and update whole project to actual Compiler
settings etc...
Then you need the path settings to your demands:

PROGRAM SystemFile
VAR
( The file names can be adapted )
szFileName : STRING(128) := '/home/pi/Test.txt';
szFileNameCopy : STRING(128) := '/home/pi/TestCopy.txt';
szPathName : STRING(128);

PROGRAM SystemDir
VAR
( The file names can be adapted )
sDirName : STRING:= '/home/pi/delete';
sFirstFileName : STRING:= '/home/pi/firstTest.txt';
sSecondFileName : STRING:= '/home/pi/secondTest.txt';
sThirdFileName : STRING:= '/home/pi/thirdTest.txt';

PROGRAM CAA_File
VAR
( The file names can be adapted )
sFileName : CAA.FILENAME := '/home/pi/CAAFile.txt';
sFileNameCopy : CAA.FILENAME := '/home/pi/CAAFileCopy.txt';

PROGRAM CAA_Dir
VAR
sDirNewName : CAA.FILENAME:='/home/pi/NewDirectory'; ( This path can be adapted )
sDirNextName : CAA.FILENAME:='/home/pi/NextDirectory'; ( This path can be adapted )
sFileName : CAA.FILENAME:= 'Test.txt'; ( The name for the file to be created )
