Hi,
I was trying to upload(and download) a file from my computer to Simantic S7 300 PLC. (I'm using AGLINK API to do so)
I tired with many options but i'm not able to do a file transfer. I'm pretty much new to SPS programming, so i'm not able to understand why i'm always getting "Ungueltiger Kontext Error message" or "Invalid context".
I have tried following code snippet, which also shows the same error.
public Int32 doNCK_CopyFromNC(Int32 connnr, Int32 timeout)
{
Int32 result = 0;
String filename = "";
Int32 neededlen = 1000;
Byte[] buff = new Byte[neededlen];
result = AGL4.NCK_CopyFromNC(connnr, filename, buff, out neededlen, timeout);
if(result != AGL4.AGL40_SUCCESS)
{
// Error happened
String errormsg = "";
AGL4.GetErrorMsg(result, out errormsg);
}
return result;
}
I have used a sample application that provided by DeltaLogic Company, but which giving similar issue.

Since majority of the software forum and tools are in German i'm getting difficult to search this error in internet. Can anyone here please help me on resolving this issue ?
