Hi. Some info from CODESYS bug-tracker about CAA File:

GetProperty: "This function will not be implemented, because the 3S CAA implementation should behave in teh same way on all plattforms and there is no need to retrieve implementation properties.
The function will be removed (or hidden) during the next rework of the CAA libs." (CDS-20219)
FTP/HTTP - not implemented (CDS-2697 and etc.)

Hi Everybody,

As I am writing my my own FileFactory Library. Therefore I want to check which functionalities the target runtime has.
That way the filefactory can "adapt" to the target which makes the library more flexible and more user friendly.
To achieve this, I have read into the CAA File library and the function FILE.GetProperty suits this purpose perfectly.
I linked "File Acces" 3.5.7.0, which depends on "CAA File" 3.5.11.0
According to the documentation, the function works very straightforward;

Ouput (DWORD) := FILE.GetProperty( in := Input (WORD) );

with

Input = List of global constants which act as question
Output = Anwser 0 or 1 (as DWORD) to input question
https://help.codesys.com/webapp/CAA-File%2FFunctions%2FGetProperty;product=CAA_FILE;version=3.5.11.0

To test this functionality i wrote a little testprogram to see if the function returns the targets capabilities;

//Insert File Access in Library Manager
PROGRAM GetProperty
    PDIRNAME : DWORD; // A1 
    PRENAME : DWORD; // A2 
    PCOPY : DWORD; // A3 
    PSETATTRIBUTE : DWORD; // A4 
    PFILENAME83 : DWORD; // A100 
    PCAPITALLETTERS : DWORD; //A101 
    PABSOLUTEPATH : DWORD; // A200 
    PDRIVELETTER : DWORD; // A201 
   
    // several declarations missing in global constants list 3.5.11.0 ?
    MIA210 : DWORD; //210
    MIA211 : DWORD;//211
    MIA212  : DWORD;//212
    PNETWORKDRIVES : DWORD; // A300 
END_VAR
DIRNAME       := FILE.GetProperty(wProperty := FILE.gc_PDIRNAME );      //    Support of function block FILE_DirRename
PRENAME      := FILE.GetProperty(wProperty := FILE.gc_PRENAME );      //   Support of function block FILE_Rename
PCOPY       := FILE.GetProperty(wProperty := FILE.gc_PCOPY );         //   Support of function block FILE_Copy
PSETATTRIBUTE   := FILE.GetProperty(wProperty := FILE.gc_PSETATTRIBUTE);   //   Support of function block FILE_SetAttribute
PFILENAME83    := FILE.GetProperty(wProperty := FILE.gc_PFILENAME83 );      //   Restriction of the directory and file names to 8.3 format
PCAPITALLETTERS := FILE.GetProperty(wProperty := FILE.gc_PCAPITALLETTERS );   //   Restriction on capital letters for directory and file names
PABSOLUTEPATH     := FILE.GetProperty(wProperty := FILE.gc_PABSOLUTEPATH );   //   Restriction on absolute path specification
PDRIVELETTER     := FILE.GetProperty(wProperty := FILE.gc_PDRIVELETTER );   //   Support of drive letters
// missing constants?
MIA210 := FILE.GetProperty(wProperty := 210 ); //Support of Resolver Syntax for file names
MIA211 := FILE.GetProperty(wProperty := 211 ); //Support of FTP-Client functions
MIA212 := FILE.GetProperty(wProperty := 212 ); //Support of Http-Client functions
PNETWORKDRIVES := FILE.GetProperty(wProperty := FILE.gc_PNETWORKDRIVES );   //

Now, I ran this code on target x86 non RT, x64 non RT and RPi3, all v3.5.11.0, without ANY of the anwsers becoming "1" at runtime on all 3runtimes.

I assume this cannot be correct behaviour, am I doing something wrong? If so, what am I doing wrong?
I checked the input on the function and I think that works fine, the function has a valid argument and is called correct.

Q1: Can someone check my findings on the non-performing of the FILE.GetProperty function?
Q2: Are the 3 constants missing by design? E.G.;
MIA210 := FILE.GetProperty(wProperty := 210 ); //Support of Resolver Syntax for file names
MIA211 := FILE.GetProperty(wProperty := 211 ); //Support of FTP-Client functions
MIA212 := FILE.GetProperty(wProperty := 212 ); //Support of Http-Client functions

Many Thanx!
