  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.
