Controlling 2 stepper motors using LabVIEW

Motors - 2 NI NEMA 23 stepper motors (780073-01 and 780077-01)
Motor Power Drive - NI MID-7604
Motion Controller - NI PCI-7334
To begin with I checked that the driver can deliver the necessary power to the motors. The 780073 requires .40 amp/phase and the 780077 requires .67 amps/phase. The driver I selected supplies 1.4 amps so the motors should work with the driver. I will be using LabVIEW for the first time this upcoming week so I'm trying to do some studying on the program this weekend. I have seen some people use Boolean structures to control when specific phases turn on. I found this post on this forum to be very helpful, but I don't have LabVIEW on my laptop right now. Can anyone please explain to me the steps (specifically what each icon means) that this person is taking and whether or not this is something that I can use?

Thank you,

The 7334 controller come with a set of VIs, you should use these VIs (http://zone.ni.com/reference/en-XX/help/372134F-01/ni-motion_vi_help/about_ni-motion_software/). The thread you're refering to use DIO card to drive the motors so it is not relevant with your hardware.
If you never used LabVIEW I recommand you take a look at basic tutorials before anything else.
