CTA (Cherenkov Telescope Array) will be the largest ground-based gamma-ray observatory ever built. Two arrays are foreseen to be build, one in the Southern and one in the Northern hemisphere. A prototype for the Medium Size Telescope (MST) type (diameter: 12 m) will be installed in Berlin in early 2012. This MST prototype will be composed of the mechanical structure, drive system and mirror facets with an active mirror control system. The stability of the mechanical structure will be investigated with CCD cameras and a weather station. Furthermore the ALMA Common Software (ACS) distributed control framework will used as readout and control system for the MST, allowing to evaluate the software with the future use for the whole CTA array in mind. The design of the control software is following the concepts and tools under evaluation within the CTA consortium, like the use of a UML based code generation framework for ACS component modeling, and the use of OPC Unified Architecture (OPC UA) for hardware access. In this contribution the progress in the implementation of the control system for this CTA prototype telescope is described.
