  Software becomes a key factor for the efficient use of beamtime at synchrotrons and other facilities. Especially for macromolecular crystallography beamlines (MX) data acquisition software starts to make the difference that leads to a competitive advantage. The MX beamlines at the PSI are addressing this issue with the data acquisition software DA+. DA+ is a concept, design and implementation consisting of loosely coupled services and components written in Python and Java. The major components making up the system are the UI, acquisition engine, hardware/detector and online processing. These components are connected via messaging and streaming technologies. The main focus of the software lies on "ease of use", "simplicity", and "immediate feedback". Efficient raster scanning of samples, near real time analysis of the collected raster data and support for standard as well as advanced data acquisition protocols such as multiple anomalous diffraction data acquisition are some examples to name. In this paper the details on these and other features of the software, as well as the underlying concept, will be unveiled.
