Hello all,
I am quite
a newbie with Labview I am having problems using FTP getfile VI with big files
and a slow connection. I am getting the 56 error (user system timeout), but I
do not find how to change the timeout value.
As the high
level VI does not allow changing the timeout value I tried to use the
intermediate FTP VIs. However, it seems that changing the timeout value in the OpenConection
VI(the only one with this input parameter) does not have any effect in the timeout while
transferring files. It seems as if this value is only used when starting the TCP
connection but not later.
Afterwards,
I was searching in the labview help how to change this value and I found that
the there was TimeOut directive that can be changed in the Internet Toolkit
configuration file. But I was not sure if this includes the FTP connections and
also I am not sure about where the file is. Labview help does not specify
neither the path nor the name of this file, and the only similar file I found
was the: .\labview2009\internet\internet.ini
file, but adding the “TimeOut=value” line does not have any effect.
Can someone
explain me where are the FTP VIs obtaining the timeout value from? As the 56 error
description is “user-specified or system time limit error” I thought that this
value should be adjustable by the user in Labview, but, am I wrong? Should I
change it in Windows? Or is it related to the network or FTP server?
And
finally, the strangest thing is that, even if I get the timeout error, the
files seem to be correctly received. Anyway we do not want to have this error
appearing as the sender will be always thinking that something might have
happened and neither do we want to filter it because sometimes the error maybe
caused by a real failure in the network.
I would be
very grateful if someone could help me. Thank you very much!
Yolanda
