	Sirius is the new Brazilian Synchrotron and will be finished in 2018. Based on experiences at LNLS UVX light source along with researches and implementations, we present our new approach to develop user interfaces for beamlines control. On this process, the main tools explored are Python, Qt and some Python libraries: PyQt, PyDM and Py4syn. Powerful resources of these modules and Python straightforward coding guarantee flexible user interfaces: it is possible to combine graphical applications with intelligent control procedures. At UVX, EPICS and Python are software tools already used respectively for distributed control system and control routines. These routines often use Py4Syn, a library which provides high-level abstraction for devices manipulation. All these features will continue at Sirius. More recently PyQt turned out to be a compatible and intuitive tool to build GUI applications, binding Qt to Python. Also PyDM offers a practical framework to expose EPICS variables to PyQt. The result is a set of graphical and control libraries to support new user interfaces for Sirius beamlines.

	With the increased performance provided by 4th generation synchrotron light sources, precise motion control and event synchronization are essential factors to ensure experiment resolution and performance. Many advanced beamline systems, such as a new high-dynamic double crystal monochromator (HD-DCM), are under development for Sirius, the new machine under construction in Brazil. Among the expected performance challenges in such applications, complex coordinated movements during flyscans/continuous scans, hardware synchronization for pumpÂ-and-Âprobe experiments and active noise suppression are goals to be met. Two architectures are proposed to cover general-purpose and advanced applications. The HD-DCM controller was implemented in a MATLAB/Simulink environment, which is optimized for RCP. Hence, its software must be adapted to a more cost-effective platform. One candidate controller is the NI cRIO. The portability of both MATLAB and NI PXI, the present standard control platform at LNLS, codes to cRIO is evaluated in this paper.

Sirius is the new Brazilian Synchrotron and will be finished in 2018. Based on experiences at LNLS UVX light source along with researches and implementations, we present our new approach to develop user interfaces for beamlines control. On this process, the main tools explored are Python, Qt and some Python libraries: PyQt, PyDM and Py4syn. Powerful resources of these modules and Python straightforward coding guarantee flexible user interfaces: it is possible to combine graphical applications with intelligent control procedures.

With the increased performance provided by 4th generation synchrotron light sources, precise motion control and event synchronization are essential factors to ensure experiment resolution and performance. Many advanced beamline systems, such as a new high-dynamic double crystal monochromator (HD-DCM), are under development for Sirius, the new machine under construction in Brazil. Among the expected performance challenges in such applications, complex coordinated movements during flyscans/continuous scans, hardware synchronization for pumpÂ-and-Âprobe experiments and active noise suppression are goals to be met. Two architectures are proposed to cover general-purpose and advanced applications. The HD-DCM controller was implemented in a MATLAB/Simulink environment, which is optimized for RCP. Hence, its software must be adapted to a more cost-effective platform. One candidate controller is the NI cRIO. The portability of both MATLAB and NI PXI, the present standard control platform at LNLS, codes to cRIO is evaluated in this paper. Control resolution, acquisition rates and other factors that might limit the performance of these advanced applications are also discussed.
