The particular middleware framework used in many of DVel\u2019s system solutions is \u2018LabQT\u2019. This framework is freely available for download and integration in any suitable project. LabQT have been in use and evolved since its introduction in 2009. It is currently actively developed and maintained by the DVel engineers.<br \/>\u200b<br \/>LabQT utilizes object orientation and other well-known frameworks in order to make the system scalable and enable several developers to work effortlessly in parallel. In this project standard and common functionality was reused from the LabQT framework, making the development cost effective with reduced test time and increased stability. With a modular design it was possible to test the different parts of the code independently and in an early stage of the project. This was important, since the hardware was developed in parallel with the software, and the time for commissioning of the final product was limited.<\/p>\n<h4><\/h4>\n<h4><\/h4>\n<h4>Custom solutions<\/h4>\n<p>Much of the standard control system application functionality, such as error handling, logging and feedback control, could be reused from standard libraries within the LabQT framework.
