S13MMI01 | Workstations as Consoles for the CERN-PS Complex, Setting-Up the Environment | 446 |
|
||
Within the framework of the rejuvenation project of the CERN control systems, commercial workstations have to replace existing home-designed operator consoles. RISC-based workstations with UNIX®, X-window¿ and OSF/Motif¿ have been introduced for the control of the PS complex. The first versions of general functionalities like synoptic display, program selection and control panels have been implemented and the first large scale application has been realized. This paper describes the different components of the workstation environment for the implementation of the applications. The focus is on the set of tools which have been used, developed or integrated, and on how we plan to make them evolve. | ||

S13MMI02 | General Man-Machine Interface Used in Accelerators Controls: Some Applications in CERN-PS Control Systems Rejuvenation | 452 |
|
||
A large community is now using Workstations as Accelerators Computer Controls Interface, through the concepts of windows - menus - synoptics - icons. Some standards were established for the CERN-PS control systems rejuvenation. The Booster-to-PS transfer and injection process is now entirely operated with these tools. This application constitutes a global environment providing the users with the controls, analysis, visualization of a part of an accelerator. Individual commands, measurements, and specialized programs including complex treatments are available in a homogeneous frame. Some months of experience in current operation have shown that this model can be extended to the whole project. | ||

S13MMI03 | The Replacement of Touch-Terminal Consoles of the CERN Antiproton Accumulator Complex (AAC) by Office PCs As Well as X-Windows Based Workstations | 456 |
|
||
With aging hardware and expensive maintenance and replacement possibilities, it was decided to upgrade the CERN Antiproton Accumulator Complex (AAC) touch terminal consoles with modern hardware. With significant amount of operational application software developed with touch terminals over 10 years, the philosophy adopted was to attempt a total emulation of these console functions of touch actions, graphics display as well as simple keyboard terminal entry onto the front-end computer controlling the AAC. The PC based emulation by mouse and multiple windows under MS-DOS and later, under the Windows 3 environment was realized relatively quickly; the next stage was therefore to do the same on the Unix platform using software based on X-Windows. The communications channel was established using the TCP/IP socket library. This paper reviews this work up to the operational implementation for routine control room usage for both these solutions. | ||

S13MMI04 | The Elettra Man-Machine Interface | 460 |
|
||
ELETTRA is a third generation Synchrotron Light Source under construction in Trieste (Italy), with beam energies between 1.5 and 2 GeV. Two networks connect three layers of computers in a fully distributed architecture. An ergonomic and unified approach in the realization of the human interface for the ELETTRA storage ring has led to the adoption of artificial reality criteria for the definition of the system synoptic representation and user interaction. Users can navigate inside a graphic database of the whole system and interactively edit specific virtual control panels to operate on the controlled equipment. UNIX workstations with extended graphic capabilities as operator consoles are used in the implementation of the PSI (Programmable Synoptic Interface), that was developed on top of X11 and the Programmer’s Hierarchical Interactive Graphics System (PHIGS) standards. | ||

S13MMI05 | Exploiting the X-Window Environment to Expand the Number, Reach, and Usefulness of Fermilab Accelerator Control Consoles | 464 |
|
||
The Fermilab accelerator operator workstation of choice is now the Digital VAXstation running VMS and X-Window software. This new platform provides an easy to learn programming environment while support routines are expanding in number and power. The X-Window environment is exploited to provide remote consoles to users across long haul networks and to support multiple consoles on a single workstation. The integration of imaging systems, local datalogging, commercial and Physics community’s software, and development facilities on the operator workstation adds functionality to the system. The locally engineered knob/pointer/keyboard interface solves the multiple keyboard and mouse problems of a multi-screen console. This paper will address these issues of Fermilab’s accelerator operator workstations.

S13MMI06 | A Virtual Control Panel Configuration Tool for the X-Window System | 468 |
|
||
Funding: Work supported and funded under the Department of Defense, US Army Strategic Defense Command, under the auspices of the Department of Energy. Computer Graphics Workstations are becoming increasingly popular for use as virtual process control and read back panels. The workstation’s CRT, keyboard, and pointing device are used in concert to produce a display that is in essence a control panel, even if actual switches and gauges are not present. The code behind these displays is most often specific to one display and not reusable for any other display. Recently, programs have been written allowing many of these virtual control panel displays to be configured without writing additional code. This approach allows the initial programming effort to be reapplied to many different display instances with minimal effort. These programs often incorporate many of the features of a graphics editor, allowing a pictorial model of the process under control to be incorporated into the control panel. We have just finished writing a second generation software system of this type for use with the X-Window system and the Experimental Physics and Industrial Control System (EPICS). This paper describes the primary features of our software, the framework of our design, and our observations after initial installation. |

S13MMI07 | X-Window for Process Control in a Mixed Hardware Environment | 471 |
|
||
X-Window is a common standard for display purposes on the current workstations. The possibility to create more than one window on a single screen enables the operators to gain more information about the process. Multiple windows from different control systems using mixed hardware is one of the problems this paper will describe. The experience shows that X-Window is a standard per definition, but not in any case. But it is an excellent tool to separate data-acquisition and display from each other over long distances using different types of hardware and software for communications and display. Our experience with X-Window displays for the cryogenic control system and the vacuum control system at HERA on DEC and SUN hardware will be described. | ||

S13MMI09 | Porting Linac Applieation Programs to a Windowing Environment | 479 |
|
||
We report our experience in porting Linac application programs written for CAMAC controlled hardware consoles to an X·Windows/Motif based workstation environment. Application programs acquire their parameter values from a front end computer (FEC), controlling the acceleration process, via a local area network. The timing for data acquisition and control is determined by the particle source timing. Two server programs on the FEC for repetitive acquisition and command-response mode will be described. The application programs on the workstations access a common parameter access server who establishes the necessary connection to the parameters on the FEC. It displays the parameter’s current values and allows control through Motif interactive synoptics editor and its corresponding driver program allow easy generation of synoptics displays and interaction through command panels. | ||

S13MMI10 | A New Workstation Based Man/Machine Interface System for the JT-60 Upgrade | 483 |
|
||
Development of a new man/machine interface system was stimulated by the requirements of making the JT-60 operator interface more "friendly" on the basis of the past five-year operational experience. Eleven Sun/3 workstations and their supervisory mini-computer HIDIC V90/45 are connected through the standard network; Ethernet. The network is also connected to the existing "ZENKEI" mini-computer system through the shared memory on the HIDIC V90/45 minicomputer. Improved software, such as automatic setting of the discharge conditions, consistency check among the related parameters and easy operation for discharge result data display, offered the "user-friendly" environments. This new man/machine interface system leads to the efficient operation of the JT-60. | ||

S13MMI11 | A Flexible Graphic Display System for Accelerator Control | 487 |
|
||
A flexible graphic display system for controlling the KEK Photon Factory storage ring has been developed. A VME computer locally controls the graphic display system and communicates with the host control computer through a RS-232C link. Graphic pictures are prepared in the local system by an interactive operation using either a tablet or a keyboard. The host control computer is free from any load due to graphics processing. In an on-line operation, pictures are displayed and modified by simple command strings from the host computer. A "picture stack" method has been developed for this graphics system. The latest demanded picture always has top priority to be presented on each display monitor. Previous pictures are saved in a stack and can reappear when the current picture has been freed. | ||

S13MMI13 | Correlation Plot Facility in the SLC Control System | 493 |
|
||
Funding: Work supported by Department of Energy contract DE-AC03-76SF00515. The Correlation Plot facility is a powerful interactive tool for data acquisition and analysis throughout the SLC. This generalized interface allows the user to perform a range of operations or machine physics experiments without the need for any specialized analysis software. The user may step one or more independent parameters, such as magnet or feedback setpoints, while measuring or calculating up to 160 other parameters. Measured variables include all analog signals available to the control system, as well as calculated parameters such as beam size, luminosity, or emittance. Various fitting algorithms and display options are provided. A software-callable interface has been provided so that a host of applications can call this package for analysis and display. Such applications regularly phase klystrons, measure emittance and dispersion, minimize beam size, and maintain beam collisions at the interact ion point. |

S13MMI14 | Iconic Representation of Particle Beams Using Personal Computers | 496 |
|
||
The idea of representing the character of a charged particle beam by means of its emittance ellipses, is essentially a mathematical one. For quick understanding of the beam character in a more user-friendly way, unit beam cells with particles having a uniform nature, have been pictured by suitably shaped 3-D solids. The X and Y direction momenta at particular cell areas of the particle beam combine together to give a proportionate orientation to the solid in the pseudo 3-D world of the graphic screen, creating a physical picture of the particle beam. This is expected to facilitate the comprehension of total characteristics of a beam in cases of online control of transport lines and their designs, when interfaced with various ray-tracing programs. The implementation is done in an IBM-PC environment. | ||
