The near-infrared interferometric imaging camera for the Large Binocular Telescope, LINC-NIRVANA, is equipped
with dedicated multi-conjugated adaptive optics systems and will provide an unprecedented combination of angular
resolution, sensitivity, and field of view.
Tight requirements resulting from long exposure interferometric imaging over a large field of view need to
be fulfilled. Both incoming beams have to coincide in the focal plane of the science detector. Their pointing
origins, offsets, orientations, and plate scales have to match each other and must not change during observations.
Therefore, active beam control beyond fringe tracking and adaptive optics is essential. The beams need to be
controlled along the complete optical path down to the combined focal plane.
This paper describes the beam control aspects from a software-centric point of view. We give an outline on
the overall distributed control software architecture of LINC-NIRVANA. Furthermore, we center on the beam
control specific features and related functionality as foreseen and implemented in the LINC-NIRVANA software
