QNX 4.25 Evaluation Executive Summary
During the summer of 1998, Real-Time Consult officially
started an RTOS evaluation program. First, Windows NT and the real-time
extensions to Windows NT were studied. The evaluation report on QNX 4.25
from QNX Software Systems Ltd. was part of this evaluation program.
These evaluation reports, as well as comparison reports
highlighting decision-critical information, are available on our Web site
at http://shop.realinter.net/rtshop/.

Nucleus OSEK: Real-time kernel for the automotive
industry based on Nucleus PLUS
Nucleus OSEK is Accelerated Technology's full-featured
implementation of the OSEK/VDX Operating System. (The Communication and
Network Management modules are additional products available to support
Nucleus OSEK.) Nucleus OSEK was developed specifically for embedded applications
in the automotive industry. Care has been taken to produce a product that
is fully compliant with the OSEK specification version 2.0. Because of
Accelerated Technology's existing source code, no royalty business model,
and the way current Nucleus products are developed, it made sense to become
an early participant in OSEK technology.

Running Linux Applications in an Embedded, Real-Time Environment
Following its success in the server market, Linux is
generating a lot of interest as the new OS of choice in embedded and real-time
devices. However, because the Linux kernel was not originally designed
for these types of applications, it faces a number of interesting technical
challenges that must be overcome if it is to gain widespread acceptance
in this market. This paper starts with a discussion of the architectural
features of the Linux kernel, with particular emphasis on showing where
there is a good match with the requirements of the embedded market and
where problems exist. The paper then goes on the present a comparison of
the different approaches that have been used to adapt Linux for real-time
and embedded systems.

High-Availability Communications Requires Embedded
Hardware and Software
As the telecomm market wrestles
with the convergence of voice, data and video onto a single, reasonably
priced line, the need for high availability cannot be overlooked - as Fred
Rehhausser, Lori S. Grob, and Thomas Cheng of Sun Microsystems explain.

OPEN AUTOMATION PLATFORM
The wish for open and yet integrated systems in the field
of automation arises more and more, as these systems make it possible to
combine the components of different manufacturers, to have a wide range
of products to select from, which then (optimally integrated) represent
a suitable, individual automation solution. With MULTIPROG® wt KW Software
has developed a platform to integrate different tools for programming,
visualization and bus connection purposes.

DeviceNet simplifies warehouse design
A DeviceNet I/O controller is being used to upgrade a
PLC-based mobile pallet racking system. Custom designed for low temperature
requirements, the board implements a slave DeviceNet function, combined
with two types of I/O: solid-state relay outputs to switch the contactors
for the motors that move the racks, and opto-isolated digital inputs for
manual command devices and the sensors on the racks which provide position
information. This article reviews the application, the solution provided,
and introduces the DeviceNet specification.

AS-Interface Slaves for frequency inverters
Intelligent slaves to connect frequency inverters to
the Bussystem which networks binary sensors and actuators.
The AS-Interface has become the standard bussystem to
network binary sensors and actuators at the lowest field level. In industrial
plants the problems of electrical drive technology have been solved conventionally.
The following article is about how to combine frequency inverters and the
AS-Interface in an effective way and what advantages the user gets using
this combination.

Data Acquisition and Control in a User-Mode Real-Time System for
Electrochemical Equipment Automation
The paper considers the characteristics of the user mode
real-time system that was implemented in a series of programs for electrochemical
equipment automation. This simple real-time system uses efficiently the
potential of ISA-bus data acquisition and control boards and conciliates
the requirements of time-critical and slow stages in time resources in
the computerized electrochemical experiment.

An automatic maintenance system for nuclear power plants instrumentation
Maintenance and testing of reactor protection systems
is an important cause of unplanned reactor trips due to be commonly carried
out in manual mode. The execution of surveillance procedures in this mode
entails a great number of manual operations. Automated testing is the answer
because it minimises test times and reduces the risk of human errors. GAMA-I
is an automatic system for testing the reactor protection instrumentation
which is based on VXI instrumentation cards.
This system has important advantages over previous ones
in terms of easiness to carry out software modifications related to configuration
changes in the protection system. The system uses visual programming and
the modifications can be implemented by ordinary instrumentation specialists
without programming experience.

Iborra, Cartagena University, and Carlos Fernández, Madrid University.

Real-time Control on Ethernet
This article first gives you an introduction about the
use of Ethernet networks in general. And it discusses the problems of Ethernet
usage in real-time applications. To solve these poblems, different protocols
have been developed. ControlNet’s Control and Information Protocol (CIP)
is one of these protocols and this is what the rest of this article tells
you more about.

i++;
As timing is very variable on different types of modern
CPU’s, is becomes very difficult for real-time Java programmers to determine
how many cycles a given piece of compiled Java consumes. Therefore we take
a closer look at the tools that can help you solve this problem.
