how do I generate shared variable RT read buffer empty error code's?

[qing_shan61]

I use a desktop Windows 7 PC communicate with a sbRIO9626.  I sent a array of 5 doubles from host to RT through a shared variable 'UI2RT', which is networked-published, RT FIFO enabled (single element, 5elements), I always read the errorcode as '0'.  Why can I not get '-2220', instead.  Please help.

Thank you in advance,

Kind regards,

Qing

Check the variables timestamp for new values instead of waiting for an error.
