Software complex Sonix (SOftware for Neutron Instruments on X11 base) was initially developed for the Neutron Spectrometer with High Resolution(for VME-computer in the OS-9environment) at the IBR-2 reactor. Since that it was significantly improved and installed at the most IBR-2 instruments. FLNP.
Sonix milestones
1995. The first control system based on the modular VME-computer with operational system OS-9 has been created at the NSHR diffractometer at the IBR-2 reactor. The NSHR complex is organized as a community of X-clients implemented on the base of X11/OS-9 package. Simple script interpreter was included.
1997-1998. Complex is installed at SKAT, NERA-PR and Epsilon instruments.
1999-2002. Complex was modified greatly and installed at YuMO, DN-2, SPN, DN-12, FSD and HRFD instruments.
Main improvements are:
- former X-clients were separated into «resident» and «interface» parts;
- use of a real time database (Varman from IRI TU Delft) for module communication;
- script language enhancements.
A script file is provided. Script interpreter is Modules have two modes: ‘manual’ and ‘auto’ for script control A local version is the same as distributed Clients are configured by a common configuration file.
Basic Sonix features
- The VME computer is used for the whole job
- The complex has modular structure. Each module completely controls a single spectrometer unit (goniometer etc.)
- GUI modules (interfaces) were separated
- The inter-client communication is implemented with Varman real time database(Varman)
- Clients are configured by a common configuration file.
- Modules have two modes: ‘manual’ and ‘auto’ for script control
- A local version is the same as distributed
- In case of fatal error system automatically restarted to continue mesurement
- Private script generators and tuning programs are present
From Sonix to Sonix+
PC(Windows) vs. VME(OS-9)
- Using PC with Windows for instrument control reduces the overall costs of the system
- Users are more experienced with the Windows environment
- Many useful software products are available
Sonix disadvantages
- GUI - many windows to control complicated systems
- No common protocol for module communication
- The script language is rather poor
- The configuration file is too complicated to edit manually
In 2003 – Sonix+ was initiated In 2004 – It was installed at NERA-PR and REMUR instruments (IBR-2) In 2005 – Versions for YuMO (IBR-2) and DSD (Yekaterinburg) instruments are ready to use In 2007 - the complex was installed at the GEK3 и GEK5 instriuments(Obninsk) and MOND instrument (Moscow, Kurchatov institute)
Причины перехода на платформу Windows (PC)
- дороговизна модификации аппаратуры VME систем и средств разработки для OS-9
- затруднения с организацией on-line визуализации, особенно для многомерных спектров
Отличия Sonix+ от Sonix
- Межмодульное взаимодействие полностью стандартизировано (унифицированы протокол и интерфейс)
- Возможно объединение устройств с получением нового качества
- Пользователь взаимодействует с устройствами, а не модулями
- В качестве скрипт языка системы используется Python
- Ведется единый протокольный файл
- Организовано автоматическое сохранение измеренных данных, а также преобразование в формат пользователя с принятой схемой именования
- GUI организован универсально и более удобно
- Реализация в среде Windows
