	After about two years in operation the bunch-synchronized data acquisition as used with the accelerator control system at the European XFEL is being revisited and reevaluated. As we have now gained quite some experience with the current system design it was found to have shortfalls specifically with respect to the offered methods for data retrieval and management.

	In September 2017 the European XFEL entered user operation after years of construction and one year of commissioning. To provide a fast and flexible startup of the various sections of the machine, the high-level control software was essential from the beginning. While progressing in commissioning and increasing operation parameter space, the enormous complexity of the European XFEL put hard requirements on the control and operation concepts.

Revisiting the Bunch-Synchronized Data Acquisition System for the European XFEL Accelerator

After about two years in operation the bunch-synchronized data acquisition as used with the accelerator control system at the European XFEL is being revisited and reevaluated. As we have now gained quite some experience with the current system design it was found to have shortfalls specifically with respect to the offered methods for data retrieval and management. In the context of modern data collection and management technologies readily in use by huge internet companies, new frameworks are being evaluated as a control-system independent replacement for data reduction, processing and online analysis. The main focus here is currently put on streaming technologies. Different approaches are being discussed in this paper and reviewed for feasibility and adaptability for control system architectures used at DESY’s accelerator facilities.

Review of Commissioning and First User Operation in Respect to High Level Controls at the European XFEL

In September 2017 the European XFEL entered user operation after years of construction and one year of commissioning. To provide a fast and flexible startup of the various sections of the machine, the high-level control software was essential from the beginning. While progressing in commissioning and increasing operation parameter space, the enormous complexity of the European XFEL put hard requirements on the control and operation concepts. Having now the full baseline parameters reached, this paper will review the high-level software concepts and architecture in respect to effectiveness, reliability and ease of operation. Beside a review of the high-level software concepts and design ideas also general operation concepts and the interoperability between the various sub-systems in respect to the overall facility performance will be presented.
