DataSocket Read problem

[Gaël Renevier]

Hi all,

When I use the new condensed "DataSocket Read" vi in Labview 6i (which is
unfortunately not editable and is supposed to replace old vi's like "open
connection", "update", "close" and so on) a single time to read automat
words through an OPC server, the vi returns "zeros" all the way. The only
solution I found to read the right datas is to place the "DataSocket Read"
in a "While Loop" which loops until datas are different from zeros, which
is very inconvenient and time consuming. I tried diffferent settings with
"DataSocket Read" (wait for update, timeout) but the problem remains.

Have you also faced the same problem ? Is there a solution ? Thanks for your
assistance.

Hello,

Select open from the file menu and browse to the following location : labview
6\vi.lib\platform\dataskt.llb. I think this library has the vi's you are
looking for. I hope this helps.

This is a problem with the 6i data socket routines ... use the old routines
from the data socket examples (with the open,update, close drivers), and it
works fine.
