Help wiring a Delta Tau UMAC to interface with labview.What is needed?

Here is an example for communicating with a PMAC.  You don't have to open and close with each command.  Actually, I usually just use the open once at the beginning of a program, then don't use the close.  You can either query the PMAC or just send commands using this VI.

Hi, Brain Beal. Thanks a lot for your material attached. But unfortunatelly, My Labview version is 8.2.1, so I can't open your VIs in folder PMAC example written by Labview 8.5. Could you please kindly save it as earlier version VIs? Thank you!

My mail box is xu.wang@delphi.com

Thanks you so much for your reply,you truly are a great person

 

here is my problem:

I've ran into the trouble of how to control and communicate with the PMAC and UMAC recently,(type:Turbo PMAC2 clipper card and UMAC CPU Control),I‘ve downloaded the examples you've posted before,but it turn out that the drivers and the ActiveX files of the PMAC has already changed that I cannot run you VI even after I setup the PMAC softwares,I tried to creat VIs the way you did but I just cannot find the Pecommserve,I guess it has changed to the Pmacserve so I used the Pmacserve instead but errors just come up,I was so confused and I cannot find any other example neither,could you help out,I would be very very appreciate your help,Thanks a million!

I just set up a new Clipper this week with Labview using the same VI's.  What Delta Tau software package did you install?  I noticed that there is an error in the PcomGetRespEx.vi that I posted.  It has a spare VI in the block diagram.  Delete the Pcom Open Close VI.  You need to be sure to set up the PMAC with the Delta Tau software.  Can you communicate using Pewin32Pro2?

It depends on how well you understand the PMAC.  You must have a good understanding of the PMAC before you can control it from Labview.
