	Funding: This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. LabVIEW software is often chosen for developing small scale control systems, especially for novice software developers. However, because of its ease of use, many functional LabVIEW applications suffer from limits to extensibility and scalability. Developing highly extensible and scalable applications requires significant skill and time investment. To close this gap between new and experienced developers we present an object-oriented application framework that offloads complex architecture tasks from the developer. The framework provides native functionality for data acquisition, logging, and publishing over HTTP and WebSocket with extensibility for adding further capabilities. The system is scalable and supports both single process applications and small to medium sized distributed systems. By leveraging the framework, developers can produce robust applications that are easily integrated into a unified architecture for simple and distributed systems. This allows for decreased system development time, improved onboarding for new developers, and simple framework extension for new capabilities.

TUPV011	Interfacing EPICS and LabVIEW Using OPC UA for Slow Control Systems	EPICS, experiment, controls, hardware	405

	The ability of EPICS-based control systems to adapt to heterogeneous architectures made EPICS the defacto control system for scientific experiments. Several approaches have been made to adapt EPICS to LabVIEW-based cRIO hardware but these approaches including NI EPICS ServerI/O Server: (1) require a lot of effort to maintain and run especially if the controllers and the process variables are numerous; (2) only provide a limited set of metadata; or (3) provide a limited set of EPICS features and capabilities. In this paper, we survey different solutions to interface EPICS with LabVIEW-based hardware then propose EPICS OPCUA device support as an out-of-the-box interface between LabVIEW-based hardware and EPICS to preserve most of EPICS features and provide reasonable performance for slow control systems.
