Linear motion technology has traditionally occupied a defined market niche and often plays a supporting role to conventional fluid power systems. Continuous developments in technology are, however, blurring the lines between linear motion, pneumatics, and hydraulics. As a result, machine and plant designers, builders and operators now have a far wider range of options for moving and positioning parts, assemblies, and mechanisms. Fluid power has been used as a source of movement, positioning and control for many hundreds of years. However, the latest developments in electrically driven linear motion technology look set to offer a viable alternative to the use of hydraulic and pneumatic devices. - Author(s): T. Ciardiello

Most of these industrial uses of wireless solutions are involved with monitoring such as telemetry applications. This paper focuses on newer emerging technologies such as BlueTooth, ZigBee and wireless Ethernet. The main motivation for industrial end users is to improve their competitiveness. There is a need to improve process operations, product quality and productivity with an ever-decreasing workforce. Industry must look to new technologies to help meet these demands. They do not use them for the sake of the technology, but for the business benefit derived from using new technology. - Author(s): D. Egan

There has been increased interest in the ZigBee standard, in particular for building automation and industrial controls. The ZigBee Alliance has identified six application spaces for ZigBee: consumer electronics, PC and peripherals, residential/light commercial control, industrial control, building automation and personal healthcare. This article deals mainly with industrial control and building automation. Increasingly, companies developing monitoring and control applications in industrial and commercial building environments are looking to wireless technologies like ZigBee to save the cost of wiring and installation and also to allow more flexible deployment of systems. - Author(s): N.

Most industry analysts are forecasting explosive growth in the use of wireless data network technologies in industrial applications. For both ZigBee and Bluetooth separate alliances of companies worked to develop specifications covering the network/link, security and application profile layers so that the commercial potential of the standards could be realized. Real industrial wireless networks are inevitably be hybrids including ZigBee/802.15.4 and Bluetooth in complementary roles that suit the characteristics of each. The key to success is in deploying the right wireless technologies for the requirements of the application and avoiding the temptation of trying to make one technology meet all needs. - Author(s): J.

Wireless is now a pervasive aspect of everyday life; from the Bluetooth module in a mobile handset to broadband wireless networks covering scores of square kilometres. No longer is wireless networking an experimental technology, it has become ubiquitous, and wireless closed-loop control is now being seriously considered for industrial applications. Wireless networking enables the vision of a security enterprise - ease of expansion with minimal implementation and maintenance costs. The bottom line is that wireless networking is cheaper. Computer-based simulation can help develop a thorough understanding of wireless control systems; the network and control system can be configured quickly and the results from modifications to either the protocol or the control strategy can be implemented and tested scientifically, without time-consuming and difficult hardware implementation. - Author(s): A.J.

The potential for using public wireless networks technologies for remote control and monitoring within all sectors of the utility industry has been recognized for sometime, however there have always been a number of concerns, both technical and commercial, which have been significant enough to hinder the wide scale adoption of such technologies in this market. The use of telecontrol in the UK electricity industry can be split into two main categories - traditional hierarchical based telecontrol systems and secondary telecontrol and automation systems. It can be seen that, generally each category has different requirements for telecoms. Traditional networks need constant real time communication between RTU (remote terminal unit) master station while the RTUs on the secondary schemes have the possibility to communicate intermittently. - Author(s): A.J.

A UK electricity distribution network operator (DNO) brought together a team of external consultants, internal IT resource, equipment suppliers, and a mobile phone operator to deliver an operational GPRS (general packet radio services) based telecontrol infrastructure capable of supporting over a thousand remotely controlled switches in the DNO's 11 kv distribution network. - Source: Computing and Control Engineering, Volume 16, Issue 2, page: 47 –47
