Abstract

HARMONI is the first light visible and near-IR integral field spectrograph for the ELT. It covers a large spectral range from 470nm to 2450nm with resolving powers from 3300 to 18000 and spatial sampling from 60 mas to 4 mas. It can operate in two Adaptive Optics modes - SCAO (including a High Contrast capability) and LTAO - or with NOAO. The project is preparing for Final Design Reviews. The IAC, as an institution participating in the consortium responsible for the design and manufacturing of HARMONI, is in charge of the pre-optics system. This large-scale subsystem requires a cryogenic test bench capable of accommodating it. At this point, the HIPOTEC cryostat comes into play. A Beckhoff PLC automates this large-scale cryostat. A Touchscreen panel or web browser carried out the operation, allowing for remote control. This system utilizes the TwinCAT PLC HMI Web Server. This PLC automates all the control processes of the cryostat, allowing the cryogenic cycle to perform automatically with just one click. It carries out this entire process safely using a state machine capable of bringing the system into operation.
