Sadly this is a slow forum where I have not got any help in the past. To get the ball rolling here some hints on the SysFileOpen. The third item is a pointer to an error code. e.g.
VAR
rte: RTS_IEC_RESULT; //Error code according to runtime error list
fh: RTS_IEC_HANDLE; // file handle
fileName: STRING[63] := '\dir\myfile.bin';
END_VAR
in code area
fh := SysFileOpen( fileName, AM_READ, ADR(rte));
good luck

Hi,
I am new to CoDeSys. I am trying to use the function SysFileOpen to open a file, I saw that on the 2.3 versione the usage was:
SysFileOpen(´filename´, ´access mode´);
How does it work on the version 3?
From the documentation I see:
SysFileOpen(´filename´, ´access mode´, pointer to an error object);
I was adding the CmpError Library to my project but doesn´t seem to recognize any of the contained error objects declared in there.
Thanks,
8Strings.
