ASTRI SST-2M Title . OPC-UA is an industry standard interface
platform independent. It was adopted in the project as an interface
between the ACS environment and the ASTRI hardware layer. In
particular, in Catania we are dealing with the development of the
OPC-UA servers for interfacing with the following ASTRI subsystems:
auxiliary for environmental monitoring: Weather Station, Sky
Quality Meter, Pludix, All Sky Monitor, Electric Field Meter, Rain
Sensor; auxiliary for calibration: UVScope, UVSiPM; control and
monitoring of infrastructure (ICT: Information and Communication
Technology); interface with PMC (Pointing Model Camera); camera and
its ancillary: Lid, Fiber Optic Calibration, Thermal Control, GPS,
CCD Alignment Cameras. The software is developed by means of Prosys
Java SDK. 1 www.brera.inaf.it/astri 2 www.cta-observatory.org

ASTRI SST-2M ASTRI Camera OPC-UA Control Software For testing
purposes, an OPC-UA client from UA-Expert was used. In the next
step an engineering GUI will be integrated to the OPC-UA Java
client from Prosys. OPC-UA Server for Test & Simulation The
ASTRI_TEST_Server, for each data-type used in ASTRI, provides an
OPC-UA variable-node. The server accepts as line argument the name
of an ASCII "ServerTable file, created from the Excel spreadsheet
by a python macro, and generates a new device in the OPC-UA
interface. In this way, you may obtain an OPC-UA server in order to
test and simulate each ASTRI device. Excel Table ServerTable Python

auxiliary instruments In accord with the ASTRI standard, for each
instrument, a SW interface between low level systems and ACS, based
on OPC-UA technology has been realized. For each auxiliary device,
as well as for any other ASTRI subsystem, an Interface Control
Document (ICD) was product. ASTRI Auxiliary OPC-UA Control Software
From each ICD an Excel spreadsheet that summarizes all commands and
configuration of the server OPC-UA has been extracted. OPC-UA
Server for ICT control and monitoring This is the OPC-UA server
used to interface the ASTRI infrastructure with the ACS world. At
the moment only four equipment of the ASTRI network have been
configured.
