How can I get a continuous square wave to the duty cycle of 50% on one of the analog lines?

Hello, I had recently just buy an analog card to our system, and I'm still very new to labview.  I have the PXI-6723, and I need to produce a wave square of 0 to 5 volts continuously.  I used the square wave generator and used a writing funtion to one of the ports.  This produces a momentary wave and that's it.  I tried to put some time a loop around the square and watched as wave function.  It produces constantly plots, but the write function always has the same thing.  If I am the writing inside the loop function I get errors.   Any help would be greatly appreciated.  Thank you, Fred

Another function to generate the square wave, to change the generation of waveform buffer (the Subvi used) and to connect a control at the entrance to offset from the base generator functions. or simply use the add function on the output waveform.
