Problems with Application Build for TPC-2106

[NC114]

I have a project that involves a Compact FP PAC and a TPC 2106 touch panel.  I plan on using the built in web server on the PAC for remote monitoring, and then I want to use the TPC as a local operator interface.  I started to create a VI to run on the TPC that uses network shared variables to communicate with the PAC.  When I go to build the executable on the TPC, I have several errors that say "missing VI or C file".  I've checked out the forum, but the suggested fix to a similar problem has not solved the problem.  Below is an excerpt from the build report:

Any suggestions?

Hi NC114,&nbsp;&nbsp;It looks like your touch panel is missing some software.&nbsp; Check out <a href="http://zone.ni.com/devzone/cda/tut/p/id/6021" target="_blank">this tutorial</a> to be sure you have all of the necessary software installed and are correctly targeting your touch panel. &nbsp;If this doesn't help, maybe give a bit more information on your hardware what you have in your VI.&nbsp;Cheers,&nbsp;

Hi Brian,&nbsp;I spent some more time playing around with things.&nbsp; I created a new project that only contained a VI on my host PC and one on the TPC-2106 and successfully used shared variables to communicate between the two.&nbsp; Next, I made another project that used shared variables to communicate between my PAC and my host PC and everything worked fine.&nbsp; I went back to my original project and tried to host shared variables on the PAC and read/write to them with my TPC and experienced the same problems.&nbsp; I looked closer at the build report and noticed that it listed errors associated with the RT FIFO on the shared variables.&nbsp; I removed the RT FIFO from my shared variables and was able to successfully build and deploy my TPC application.&nbsp; Have you run into this before?&nbsp; Do you have any other suggestions for using shared variables with a touch panel and a real time controller? &nbsp;Thanks&nbsp;&nbsp;

I was able to track down what looks to be the same issue.&nbsp; There was a bug that was reported to R&amp;D (# 54707) and was fixed in LabVIEW 8.6.&nbsp; It appears that there was a problem with RT Shared Variables using FIFO's when targeting mobile operating systems, like the one on your Touch Panel.&nbsp;Sorry for the inconvenience, and kudos to you for figuring out the problem!&nbsp; The solution would be an upgrade to 8.6, or disabling the FIFO as you have done.&nbsp; You can find a little more info comparing FIFO vs. no FIFO for shared variables <a href="http://digital.ni.com/public.nsf/allkb/7AE7075AF1B2C58486256AED006A029F?OpenDocument" target="_blank">here</a>.&nbsp; Otherwise, no more suggestions here.&nbsp; Sounds like you are well on your way with your application!
