Hi there, This may be a little late but I wrote a blog post regarding the use of a HAL (Hardware Abstraction Layer) inside a QMH. OK, it's our own flavour of QMH which we call the DQMH but the post content is still valid for your use case. In addition the example I use is based around a Power Supply; Here's the link http://www.walkingthewires.com/2015/10/21/hal-in-your-dqmh-2/ Hope it's useful Chris

Hi, The TestStand presentation I gave at NI Week 2015 regarding use of TestStand with the DQMH (Delacor Queued Message Handler) can be found here. I will be uploading the accompanying videos for the presentation during the course of the next day or so. What a shame that you can't move entirely to a TestStand based solution, it would be nice to implement a post step callback in the TestStand process model and then have the Step results captured without the developer of the client sequence having to have any knowledge of the storage mechanism. However as pointed out above , you will need LabVIEW based tests too. The LabVIEW based DQMH plays nicely with TestStand so it would not be difficult to create such a DQMH module (cloneable) to act as a "worker" using the UUT Serial Number as it's unique identifier. You could then have a results list object within this module that is populated by public API methods such as "Add Result" This worker could then periodically store results to a Local DB, XML file or whatever intermediate storage you require. SQLite is pretty lightweight as mentioned above. I'm not sure how you manage the replication of Local DB data to a central DB ? Do you use replication services ? One thing this "Results worker" could do is store the data in XML and then you could easily set up a SQL DTS job to bulk import complete results sets. I've spent a long time in test data management, there are many many ways to skin this particular cat ! EDIT: I forgot to say. The shipping examples that come with the DQMH Toolkit are duplicated in both LabVIEW AND TestStand. A video walkthrough of the TestStand examples can be found here

For the 2015 LAVA BBQ, Delacor have teamed up with author, friend of Delacor and all round outstanding guy; Steve Watts at SSDC to offer a truly unique door prize. Steve has kindly signed a copy of his book "A Software Engineering Approach to LabVIEW" but not only that. Steve has included the draft / amended pages that would have gone into any potential future second edition of his book. These are the only copies of these pages anywhere in the world and you as a LAVA member can have a chance to win them (and the signed book itself)
