The Network Computer is being touted as the alternative/replacement/successor
to the PC. Claimed advantages are lower cost and reduced maintenance effort.
Technical innovations are a network transferable interpretive programming
language (Java), network loadable objects and a simpler stylized user interface.
Some of these have been seen before in the "home-built" control
systems of the 1970s. This paper describes the advantages of our current
PC control systems, traces their development from the 1970s home-built
control systems, and speculates on the possible role of the Network Computer
in Accelerator Control Systems.

The control of many crucial subsystems in accelerators at DESY in general
and the HERA accelerator in particular are dominated by PCs at both the
front end and the console. As the PCs use various operating systems, must
intercommunicate with non-PC elements (workstations, mainframes, VME CPUs),
and are integrated into no fewer than two different control system architectures,
the HERA control system is not at all homogeneous and has its own unique
problems and solutions. In this paper we shall describe the control of
the PC-based subsystems in HERA and their integration to other subsystems,
detailing the merging of two distinct architectures. We shall also discuss
the PETRA control system, which is indeed a homogeneous control system
based entirely on PCs and provides a model for one of the architectures
used in HERA control.

Initially the Isolde Control System consisted only of PCs, running Windows
as Console Computers and DOS as Equipment Computers. Because of the success
of the powerful development tools on the Windows platform (Visual Basic,
Excel...), the Isolde desktop infrastructure has been extended to the UNIX
based PS accelerator control system. The Console - Equipment computer communication
protocol has been reviewed with the introduction of Windows 95 & NT,
and this new connectivity requirement to UNIX platforms and industrial
systems. This presentation will cover these techniques in the context of
the actual and future implementations of using PCs as Console computers.

TACO is (yet another) modern control system based on distributed objects.
Developed at the European Synchrotron Radiation Facility it has been successfully
applied to control the ESRF accelerators, beamlines and a radio telescope.
In TACO control elements are seen as objects in a distributed environment.
Actions are implemented in object classes. Classes can be written in C
(using Objects in C) or in C++. Recently TACO has been ported to PCs running
Linux, Windows/NT, OS-9000 and LynxOS. This paper will briefly describe
TACO and how it can be used on PCs to implement front-ends, back-ends,
servers and consoles.

An object-oriented package for on-line modeling and control has been
developed at the SIBERIA synchrotron radiation source complex (2.5 GeV).
The paper presents examples of implementation this C++ library for most
frequently used procedures at the accelerator ring complex. The standard
list includes the beamthreading through transport lines, injection, and
procedures for ring concerning to change and control lattice parameters.
The original library does not compete with the standard MAD or TANSPORT
codes, but allows to insert simulation in control applications. Problems
and experience to portation the C++ library, adaptation to hardware and
to high-level graphical interfaces are discussed.

The existing computer hardware at ASTRID and CRYRING is obsolete and can
not be expected to run for years to come. Therefore a new control system
had to be designed. The new system is based on Windows NT running on PC’s.
It follows the standard model: There will be one Windows NT server for
domain control, file storage, SQL database etc. Front-end computers responsible
for connection to the different devices and Console PC's, that is computers
with user/operator software, will be running on Windows NT workstations.
The primary development tool is Microsoft Visual C++. Other languages such
as LabVIEW, Pascal, Visual Basic etc. are supported through an API interface.
A highly modular and object oriented approach ensures flexibility and stability.
As far as feasible the system operates on abstract data types. Data objects
are transported between clients and servers independent of their contents.
Hardware specific interfaces are loaded dynamically having predefined abstract
interfaces. With this approach a high degree of code reuse can be obtained.

We report on the realization of a data acquisition system for a small laboratory
based on a 120 MHz Pentium PC working under the Linux operating system
and using a standard CAMAC interface. The system proved to be cost effective
with respect to other solutions as both the computer and the interface
used standard low cost technologies, while both the operating system and
the software tools (CERN standard libraries, Tcl/Tk, Gnu C compiler) were
freely available on the public domain. The performance of the system allowed
a maximum data acquisition rate higher than the CAMAC standard specifications.
Also, the multitasking capabilities of the chosen operating system helped
in running separately the data acquisition and the monitoring tasks, thus
reducing the overall dead time. Remote control of the system and data storage
was performed via a TCP/IP based network connection to a cluster of HP
workstations. (1) Universita' degli Studi di Roma "La Sapienza"

DOOCS is a distributed control system that was developed for HERA and TTF
applications. It is an object oriented system design from the device server
level up to the operator console. Class libraries were developed as building
blocks for device server, communication objects and display components.
The whole system is written in the programming language C++ and runs mainly
on Solaris, SunOS and PC's with the LINUX operating system. In the mixed
environment of PC (x86) and Sun workstation (SPARC) hardware the communication
is realized by Remote Procedure Calls (RPC) which handle the conversion
of data structures between the client and server processes. For the three
different PC and workstation operating systems the programs are compiled
from a single source. Other platforms may easily be added.

Using commercially available software tools, we have developed a portable
data acquisition and control system used for measuring various beam and
machine parameters on the Low Energy Antiproton Ring at CERN. Applications
of the system range from simple data logging to the quasi online measurement
of the cooling times of Pb54+ ions. In this paper we will describe the
software solutions that were implemented and give an example of how an
application program is generated.

Based on my personal operational experience with the PC-control system
of HERA, machine physicists and developers requirements for a control system
are discussed. Many control surfaces and procedures are derived from their
experience they made during machine studies and their participation in
routine runs. Based From their point of view the design of a control system
has to fulfill two general requirements: Firstly to enable the automation
of delicate procedures in a way that they can be executed routinely by
any operator. Secondly physicists and developers must be able to create
their own tools for diagnostics which later can be easily interpreted by
other operators. How those requirements are fulfilled in the case of the
HERA control system is demonstrated by two examples of Visual Basic applications
involving a large number of active accelerator components.

For ten years PCs have been used for various magnetic field measurement
purposes. During the production of superconducting magnets for HERA a PC-based
measurement system has been developed using a GPIB bus for the connection
of various hardware components. The software was based on DOS and FORTRAN.
Now Windows-NT is used as the operating system and this allows us to setup
a server-based platform. Programs are developed graphically using HP-VEE
for which many GPIB drivers exist. Recently a PC based magnet interlock
system has been developed for DORIS at DESY. The temperature sensors of
the magnets, the cooling water pressure sensors and other sensors are connected
to a Siemens PLC. The PLC is linked to a PC via Ethernet (Siemens H1 protocol).
The control and visualization system has been written using Visual Basic.

The cryogenic system for the HERA accelerator is operated like an industrial
plant. The liquid helium has to be produced without any interruption all
day through and up to 300 days a year. The requirements for the process
hardware are extremly high. Many components are redundant, like: compressors,
filters and even complete cold boxes. Any interruption f the cryogenic
process will cause a downtime for the HERA accelerator of at least half
a day. As a consequence the controls for the cryogenic plants also have
to meet the required reliability. As a second generation of control hardware
VME crates with 68040 processors are controlling the cryogenic installations
in the HERA tunnel. These systems are running under the realtime operating
system VxWorks. The implemented application is the widely used EPICS package.
This system, based on rugged industrial hardware and reliable realtime
software meets the upper requirements for process control. Up to now these
requirements could not be met by systems based on PC's. The implementation
of PC controls by default was connected to software from Mircosoft which
is designed for office automation but not for controls. The upper requirements
for permanent uninterrupted operations could not be met. A new development
by the company Wind-River for their realtime operating system VxWorks is
now opening the PC (hardware) market for realtime controls. The possibility
to use PC's as a basis for developing software and to use PC hardware as
a target system for controls will now enable us to use this hardware with
an excellent price/perfomance ratio in our environment. This paper will
describe the recent results to use this platform and to port the EPICS
software and the custom drivers to it. In addition the experience running
the development (under Win'95) and the target software (under VxWorks)
on the same hardware in parallel will be mentioned.

The present paper covers only one partial aspect of the real-time: ability
of the multitasking software to process external events, asyncronous relative
to computer, and to take them into account for task switching and scheduling.
The problem is particularly important for the CPU-based real-time data
acquisition or control (especially with PCs) and not so critical for, say,
DSP-based solutions. The concept of the Object-Oriented Multitasking Technology
(OOMT) has been first proposed by author and presented as a demonstration
software package (TASKS, diploma of the Borland-Contest93). The key idea
was to implement all the models of multi-tasking and multi-threading (cooperative,
preemptive and real-time) and different task scheduling strategies on the
base of the same object-oriented code with use of late binding. Some of
the OOMT approaches have been implemented for working stand-along real-time
PC programs (Lebedev Institute of Physics, Moscow), or measurement applications
for Windows (INR); some investigations for UNIX (Linux) are presently in
progress. Several trends of the contemporary development of programming
technologies have been anticipated by the OOMT. We hope some concepts to
be of interest for future development of the system-level software.

simple RS- 232 interface to slow target subsystems and including Internal
DMA with parallel electronic or Fiber- optical lines for high-speed target
Subsystems. Up to 6-8 analog input channels with sigma-delta ADC can be
organized with codec ( for example, with AD1847 ) for monitoring and control
subsystems up to 48 Kgz sample rates. The target Subsystem Development
is supported by basic Family Software Development kit on PC. More power
next generation System Architecture can be based on floating-point DSP
as master (for example SHARK), linked with target subsystems by serial
lines.

Our laboratory is faced with a problem to combine two accelerator together
in order to maintain a new machine with high power continuous electron
beam. The first accelerator is the main part of racetrack microtron injector
started up in our Institute in 1989. The second accelerator is the two
sections linac recently designed for industrial applications. The task
of new control system for new machine could be divided in two following
subtasks - upgrading by optimal and cost effective way old control system
of injector based now on CAMAC and LSI-11 minicomputers and unification
of two control systems together. We are using the same methods based on
modern hardware, software and architectural solutions: DSP technology,
shared memory approach and originally designed „family of smart devices"
for both problems. High level is developed on the base of PC compatible
computers. Standard fieldbuses and real time OSs could be used. MIL-STD-
1553B fieldbus is used now but Profibus is under consideration as additional
and basic in future fieldbus. LINUX OS is investigating as basic OS for
high level support including man-machine interface and data base. We expect
this way to allow us to replace step by step old control system by the
new one without long timeout in the accelerator operation.

Initially „family of smart devices" have been designed to implement
in control applications DSP technology and shared memory approach. DSP
technology is used as main method for control and data acquisition tasks
solving. Although the applications based on DSP technology increase initial
designing expenses and complicate equipment, it is possible to reduce the
number of analogue devices and time of designing, to raise releability,
to implement complex control algorithms and to reduce overall control system
price. Shared memory approach in control applications is used for initial
object-oriented description of the control object together with control
system. Control system architecture and style of application software development
are defined by this approach also. Due to shared memory approach the time
of application software development decreases and so reliability increases
whereas overall software price decreases. But service software for shared
memory support together with initial control object description should
be done very carefully. These principles could be implemented uder standard
Oss (including real time OSs) with using of standard fieldbuses for interconnection
between the members of „family of smart devices".

The LEAR machine is expected to be used to accumulate Pb ions for CERN's
next machine, the LHC. In order to test this scheme a number of machine
development sessions were devoted to measuring the properties of Pb ions
subject to electron cooling in a ultra-high vacuum environment. To perform
these measurements, including lifetime, cooling time and vacuum measurements,
we opted for a PC system that would enable us to develop custom programs
that can easily be modified to suit the type of measurement being made.
We will present some examples and results obtained with this system without
which many of the observations made would not have been possible.

Design and technological maintenance of "Angara-5" installation
determine the structure and composition of its control and data acquisition
systems. Specific of installation operation includes the following features:
- low frequency of working cycles (1-4 per day); - short time duration
of process under investigation (<= 10^-7 sec); - high value of electromagnetic
power ((2-8)x10^+12 Wt) and hence high level of electromagnetic noises.
Each of control system is been governed by means of its own PC-type computer.
All systems are connected by means of Ethernet lines to supervisor computer.
This one performs experimental information storage, preliminary data treatment
and presentation of the results. Software complex allows to tune the composition
and working parameters of each system according to experimental goals.
At "Angara-5" PC computers are widely used as control elements
in several diagnostics devices. As an examples, two applications of ones
are presented: - film registered oscilloscopic plots processing and film
registered images processing; - automatic X-ray spectrograph. Spectrograph
is been used to register X-ray emission of high temperature plasma during
thermonuclear investigations. Detector of the device is CCD linear matrix.
CCD data after ADC are input into PC. Software complex contains set of
codes to determine plasma electron temperature and density immediately
after experiment, that allows to estimate installation working cycle quality.

As graphical languages have grown in popularity over the past decade, they
have spread to many industries and applications. This is particularly true
for scientists working in research and development. LabVIEW is such a graphical
programming environment used in a wide variety of applications, such as
automated testing, industrial automation, laboratory automation, automotive
engineering, personal instrumentation, and more. First introduced in 1986,
LabVIEW supports a large variety of platforms including, Windows 3.1x/95/NT,
Macintosh and Power Macintosh; Sun SPARCstations; and HP workstations.
To address the needs of users working with time-critical applications and
to enhance the over-all execution speed, LabVIEW features an optimized
graphical compiler for the described platforms. In this paper we introduce
LabVIEW as a defacto industry-standard graphical programming environment
that scientists and engineers can laverage rapidly changing personal computing
market. In particular, it is demonstrated how users can combine GPIB instruments,
VXI devices, plug-in data acquisition (DAQ) boards, serial instruments,
and programmable logic controllers (PLCs) within a single application.
For large-scale applications various communication technologies can be
used: TCP/IP and UDP for networking; Dynamic Data Exchange (DDE), Object
Linking and Embedding (OLE) Automation, and Apple Events for interapplication
communication; Structured Query Language (SQL) for database connectivity;
Dynamic Link Libraries (DLLs) and shared libraries to connect with other
applications and to incorporate code written in other languages.

stands for "Multitasking Object-Oriented Network".) Present paper
covers several novelties of programming technologies, introduced by MOON
Lab. We argue in favour of MOON Lab object-oriented and event-oriented
approach to measurements and control problems. We believe that this approach
is more adequate to real world, than concept of data flows or virtual instruments.
Our experience in solving problems for beam diagnostics and numerical simulation
problems using MOON Lab enables to analyse its advantages and drawbacks.
Component-based graphical programming is also discussed from the point
of view of reusability. Components-based approach generally provides design-time
reusability and greatest flexibility and scalability. MOON Lab approach
gives less flexibility but is also provides high degree of run-time reusability.
It is a better choice for solving of several relatively small independent
problems and linking them together via a network. -- (R) LabVIEW is a registered

The paper describes some proposals and solutions to implement PC-VME connections
at the SIBERIA synchrotron radiation source complex (2.5 GeV). The control
system high level software runs on PC under Windows 95 or Windows NT operation
system and includes applications based on commercially available instrumentation
systems (LabVIEW,etc.) and applications written by control staff. The low
level software runs under OS-9 operation system on MC680x0 and includes
real-time applications. The connections between computers based on Ethernet
network. Intertask communications for real-time applications used OS-9/Internet
Library and OS-9/Internet Socket Library. Intertask communications for
high level applications used Socket library and Socket classes from MFC
4.0. For network communications the special library was developed. The
main functions of the library: -- asynchronies intertask connections; --
asynchronies data exchange; -- intertask synchronization; -- installation
the call-back functions for events; -- TCP/IP and UDP implementation.

The extracted beam channels diagnostics systems situated in 2 control rooms
were previously based on the intelligent crate controllers AKK-83 (INTEL-8080)
and the host computers SM-4 (similar to PDP11/40). This systems upgrade
was made using IBM PC/AT's linked to the IHEP's ETHERNET, and intelligent
controllers AKK-19 (INTEL- 8080). The developed software is described.
The updated beam diagnostics systems provide the significant improvement
of the control reliability and of the "operator-system" interface.

An interface between the IBM PC/AT compatible computer and the CAMAC branch
is developed. The interface meets most of the requirements of EUR-4600
standard for the multi crate CAMAC system with A-type crate controller.
The interface maps 16-bit CAMAC registers onto the PC address space and
occupies 8 Kilobytes. The CAMAC operations look like computer memory read/write
commands, hence no software driver is necessary. The CAMAC functions are
determined by state of the interface internal register. With fixed CAMAC
functions the interface allows full throughput of the CAMAC system (up
to 2 Mbytes/sec). Time parameters of CAMAC exchange supporting software
(written in C and Modula-2) are discussed.

Hardware and software system for real time processing of film information
is described. The system is based on upgraded flying spot digitizer PSP-2
on-line to E-60 computer which controls the hardware and stories the measured
coordinates in its memory. E-60 is memory mapped into the memory of PC
AT-286 which filters, checks, compresses and writes done the information.
The PC finds fiducial marks, sparks, dashed indicators etc. Used algorithms
and real implementations is discussed. Special attention have been paid
to opted friendly interface.The high level automatization have been reached,
the intervention of operator was really needed only for initialization
or to change films. The system was designed for measurement of films from
3-meter spectrometer with optical spark chambers which is used for experiments
in intermediate energy physics on ITEP 10 GeV synchrotron. The measurement
started in may 1993. 800000 events measured to the summer of the year.

Since 1994 we are developping a measure system for kicker and septa. The
system measures the current pulses of the PETRA ejection and HERA injection
devices for protons and electrons/positrons. The current pulses are transmitted
via lightwavecable to the electronic room near the control room. To measure
up to 12 signals we use 2 digital 4 channel HP oscillocopes to measure
the fast kicker pulses (the shortest has a pulse length of 1 us) and 1
PC with an National Instruments DAQ card AT-MIO 16 E1 to measure 4 pulses
with 250 kHz for each channel. To switch the signals we use 1 HP Multiplexer.
We use 1 PC to read the 2 oscillocopes and to control the multiplexer with
the GPIB bus. The data is stored on a Novell Server. The software on the
2 PCs an the controlroom software is made with LabView, a graphical programming
language. For the controlroom we have made a program that shows the pulses
from the last ejection and you can load all the pulses, that are stored
on our Novell Server. This program uses a Novell connection to our Novell
Server and is running on Windows 3.1. For the future we want to read out
all the values of the HERA/PETRA control system for our devices and store
it with our data for each shot. We are developping a client/server solution
running on Windows NT using TCP/IP for the control room program.

The HERA Proton ring consists of 137 BPM monitors and associated timing
and alarm modules, as well as over 260 BLM monitors, all of which exist
intermingled on four SEDAC field bus lines. The front end CPU attached
to these SEDAC lines must control and monitor all modules simultaneously.
The front end is in fact a 486/DX2 PC containing 4 SEDAC ATI Cards and
running MS-DOS. Besides continuously monitoring the current state of all
monitors, the front end must react promptly to events such as injection
triggers and sudden beam loss. The Console interface to this front end
consists of a variety of programs written in Visual Basic running on WINDOWS
(WIN16 or WIN32) and communicating via the PKTR protocol. In this paper,
we present some of the details behind managing such a large number of monitors
with a single MS-DOS PC.

The 16 HERA Proton collimators are controlled via one front end PC running
MS- DOS and issuing telegrams over the SEDAC field bus. The front end,
programmed in C++, is continuously monitoring collimator positions and
loss rates and can respond to commands which initiate local processes which
drive the collimators in very controlled ways, either individually or collectively,
and simultaneously if need be. The Console program interface, written in
Visual Basic, runs on WINDOWS (WIN16 or WIN32) and uses the PKTR data communications
protocol. It is allowed to run with full access in the control room and
with limited access on stations outside the control room. In this paper
we describe some of the details behind the actual collimator control from
a PC, including foisting a cooperative multi-tasking environment onto MS-DOS.

At the front end, the HERA Quench Protection System (QPS) consists of multiple
(3 per HERA Quadrant) VME CPUs running VxWorks and interfacing to intricate
electronic subsystems via the CAN Bus. The Console interface to these distributed
front ends is a PC running MS WINDOWS (WIN16 or WIN32). Specifically, the
Console program is written in Visual Basic and uses the PKTR data communications
protocol. As the control system is open, the Console program can run on
any workstation PC at DESY, as well as any of the control room Consoles.
A middle layer QPS Proxy server dedicated to archiving and configuration
tasks resides on a PC running MS DOS. In this paper we present some details
behind providing an intuitive and homogeneous interface to the operators
in the Control Room from a system of distributed front end computers, as
well as interconnecting no fewer than three operating systems to form the
composite interface.
