  Currently the proprietary networking middleware in the GSI control system is replaced by a CORBA based re-design. Rebuilding all controls components is out of scope, so existing applications as well as device specific front-end software still have to be used. The renovated middle layer has to fit between the former applications device access interface and the front-end framework. Providing similar functionality as before was a major design aspect therefore. However, the new outline, targeting more flexibility and clearity, did not completely provide the established functionality from the beginning. Several extensions, had to be added which on the other hand lead to additional capabilities for future usage of the system.

  As part of a joint project CLS, the University of Western Ontario, IBM and BigBangwidth has developed a beamline remote access system that has been demonstrated on the CLS VESPERS and the alft x-ray source facilities. This system utilizes web-browsers as a thin client that can be connected to servers at the CLS over conventional Ethernet or User Configuration Light Paths. The RBA system is based on the concept of a Service Oriented Architecture and provides access control, data acquisition, data storage and based visualization. More recently the system has been modified to permit experimental data to be streamed into third party analysis tools such as Quartz Imaging X-one. This system is now being extended to form the basis for ScienceStudio and integrated experiment management system.

  Among the candidate technologies for the Extremely Large Telescope (E-ELT) are ALMA Common Software (ACS) and LabVIEW. ACS is a CORBA-based control system infrastructure that implements a container-component model. It allows developers to focus on development of components that define application logic, with ACS-provided containers addressing infrastructural issues of distributed control systems such as remote procedure calls, logging, configuration, etc. LabVIEW is a commercial solution provided by National Instruments which allows rapid construction of user interfaces and control loops. Control loops can execute on Windows and Linux operating systems, as well as real-time control systems and FPGA circuits. In this paper, we present an approach for integration of ACS and LabVIEW. We accessed ACS from a LabVIEW user interface (both sending of data into ACS, and receiving data from ACS). Also, we accessed a real-time LabVIEW process (parts of which were executing in FPGA) from ACS – again in both directions. From the LabVIEW perspective, the approach is platform-independent as it is based on a Simple TCP/IP Messaging protocol.
