I just happened to stumble across Brooks Flow Controllers. I was looking for some examples and documentation about accessing their Smart DDE software with their external controller. Although we have some VIs from Brooks I did not find them very clean and was looking for information how to access them directly through the DDE interface of LabVIEW DSC. For that I would have to tell the software at startup to intialize the COM port so that I only have to open Advise Links to the Topic Items. The customer promised to come back to me with the documentation he had at home.

We did. There seem to be multiple VIs around. We have the Smart DDE ones which he got from Brooks, not sure if for free ;-) I found also VIs on a German reseller site for Brooks which talk directly to the intelligent controllers. Supposedly they use the HART protocol although I couldn't confirm from the VIs, as I have no experience with HART. Not that they would implement any real protocol, in fact they just send a few hardwired bytes so they would likely only work with those specific controllers.
