  The Cherenkov Telescope Array (CTA) is the next-generation ground-based gamma-ray observatory. Its design comprises close to 100 imaging atmospheric Cherenkov telescopes deployed at a southern (Paranal, Chile) and a northern (La Palma, Canary Islands, Spain) site. The inclusion of various array elements, like Large-Sized, Medium-Sized and Small-Sized Telescopes, instruments for atmosphere monitoring, etc, into the Array Control and Data Acquisition System (ACADA) poses a particular challenge which is met by an appropriate software architecture and a well-defined interface for array elements. This conference contribution describes exemplarily how the interface is implemented for the Medium-Sized Telescopes (MSTs, 12m diameter). The implementation uses the ALMA Common Software (ACS) as a framework for software applications facilitating the readout and control of telescope subsystems like the drive system or the pointing camera; the communication with subsystems takes advantage of the OPC UA protocol. It is also discussed what technologies (e.g. data bases) are used for the acquisition and storage of telescope-specific monitoring data.
