How to change the period of cFP-PWM-520 in labview program

lovexf,

Suggest you open up the Configure Attribute.vi and use Highlight Execution to determine exactly where the error is occuring.  My guess is that the error occurs in a sub vi named DS Sync Write (Word).vi.  Begining to suspect this is a Data Socket problem.  You could try writing your own vi that directly uses the datasocket functions.  This document goes into advanced data socket a bit more and some things that would keep it from working.  http://zone.ni.com/devzone/cda/tut/p/id/4499#toc1 

What field point controller are you using?

lovexf,

I may have figured this out.  As I said before, the Configure Attribute.vi is using a logos datasocket  to modify the settings on the cFP.  The vi is generating a URL with back slashes.  I'm pretty sure that a logos datasocket needs a URL with forward slashes.  I found this document.  http://digital.ni.com/public.nsf/allkb/B0C5F514A850BF8F86256DAB0047BB98  I've got a call into NI to verify that this is indeed a bug in the FP library.

lovexf,

Glad to hear that it is working.  Can you tell me which model of cFP you are using and what version of LV you have loaded?
