DAQ assistant buffer size error

Why this error? i'm trying a simple PID controller using DAQ assistant. As i'm using a PID controller in between generation and acquistion, i got this error?  I attached my .vi.


I have NI PCI-6229 as data acquisition card and i want to control a linear motor through a feedback coming from IK220 counter card for Heidenhain linear encoder.

Hi Bilkent,


Thanks for posting. What DAQ hardware are you using with the DAQ Assistant? Also, could you be more specific about the error that you are seeing? Perhaps providing the exact error text or a screenshot of the error message would be helpful. Thanks!
