Descripción
WEAVE is a wide-field spectroscopy facility for WHT which includes a
multi-object dual-beam spectrograph which will operate in the visible
wavelength range. The blue beam will cover the range 360-600 nm and the
red arm will cover the 580-960 nm range. In these ranges the
spectrograph will offer a mid-resolution ( 5000), while in three
narrower wavelength intervals, two for the blue arm and one for the red
one, the instrument will provide a high ( 20000) spectrograph
resolution. The spectrograph is currently entering the assembly and
integration phase and the first light is foreseen in 2019. The entire
WEAVE project is managed by an international consortium led by the
University of Oxford. The spectrograph is controlled by a coordination
process, the so called High-Level Server, which is part of the
Observatory Control System (OCS) software suite, and is the single point
of access to the embedded control system, the so called Low-Level
Control Software, which is based on PAC technology. This paper describes
the design of the embedded software for the control of the spectrograph
mechanisms. We first describe the interface between high and low level
software, then we present the PAC architecture and discuss the low-level
state machine. Finally, we provide details on the principal program
routines and describe the engineering interface.
