I'm new to Beckhoff & I have EK1100 with EL2809 & EL3054. I want to interface with EK1100 with LabVIEW without using PXI or cRio or any other hardware.
Unfortunately that isn't possible without an RT PC. You could setup an RT PC and use that instead of a cRIO or pxi however. There are several white papers on the requirements for a PC to be used with LV real time.
