A clear and realistic set of objectives goes a long way in driving continuous improvements in electrical safety. Resources can be allocated and priorities can be defined once objectives are set. The risk control hierarchy (RCH) in the ANSI-Z10 standard provides electrical safety professionals with an excellent roadmap for setting the right safety objectives that result in the reduction of electrical risks. RCH helps improve a plant electrical safety program and inspires manufactures to improve their electrical equipment designs. RCH provides a mean to measure the effectiveness of an electrical safety initiative much the same way a project management uses financial measurements to evaluate a project.

With the economy slowing down on a global basis, managers are reluctant to spend money or move forward on prior plans. Indeed, many companies are postponing or cancelling projects and many have begun cost cutting measures that almost always mean job eliminations.Reducing costs is a responsible management action; the goal is to protect the return on the investors equity. Video can provide a solution to many of the issues that remain, even when people are laid off or factories are closed.
KPIs are an excellent performance measurement tool that businesses in many different sectors employ to improve performance. The key to KPIs is finding a way to quickly gather and simply distribute the key business information without becoming beholden to large, complex databases and applications. The problem is that somewhere along the line the burden imparted by gathering and compiling month-end KPIs has become greater than the value these sometimes outdated numbers represent. How much effort, custom coding, and cost must go into compiling and communicating these measures?
Portal technology is invigorating todays corporate environments. The business world began to take portal technology seriously when the price to acquire start-up portal sites, such as My Space and Flickr, exceeded all anticipated market values. Today, portals are big business. Corporations ranging from SAP to Microsoft are investing millions of dollars in portal technology. New technology frameworks and architecture have changed the direction of portal solutions from recreational portals to the enterprise. Networking technology enables users to access portal-based web sites from anywhere and through any device that can connect to the internet. The purpose of this paper is to help you determine how your company can benefit from a portal environment, and from the OSIsoft suite of visualization components. For the first time, you can combine data stored in PI with enterprise systems and other data sources into easily accessible information, visible to individuals, teams, sites, and the enterprise.
Industrial enterprises must squeeze the most out of their assets in today's challenging business environment. The price of entry into many markets is operational efficiency plus effective, real-time reaction to changes in internal or external market conditions. Read this white paper to learn how you can boost your company's ROA by maximizing your asset performance strategy.
Manufacturers are under extreme pressure to increase operational efficiency as a means to increase reliability and maintain margins. Six Sigma is providing a powerful means for companies to improve performance. The use of this methodical, statistics-based approach is increasing across a range of industries. Those in the process industries are discovering the PI System can provide critical support to Six Sigma teams at every step of their effort. This paper discusses how to the PI System can support a Six Sigma initiative. QNI, an Australian minerals resource company, serves as an example.
Energy and information are a significant and growing fraction of manufacturing costs and require lifecycle cost management. New facilities will have to be built and operated in order to conserve resources, and existing facilities will have to be upgraded cost effectively. This is not new economics, regulation, and innovation drive business economics but today the external environment is even more dynamic and requires an appropriate response.
There is little a user can do about regulation, epoch technology breakthroughs, or market changes except monitor their effect and be prepared to change their business strategy; improved management of energy and information, however is under their control.
This white paper provides a description of the utility market, the changes that we can expect, and the reasons behind these changes. It also describes guidelines for the industrial user to develop a dynamic energy response.

Manufacturing companies have invested large amounts of money in industrial automation infrastructures, but many have yet to realize the full value from their investment as many of these infrastructures remain islands of automation; information silos disconnected from other systems, including business systems. This paper discusses some of the options available for integrating automation islands and for distributing information at any level in the organization. Real world examples will be presented to show benefits provided by open architectures.
Fieldlevel wiring used to be very simple. A sensor was either powered or passive. But when networking PLCs and PACs into the control system network became both practical and popular, engineers started thinking about how to provide power over the same set of wires as the network connection. This white paper discusses how Power over the Ethernet is fast becoming the standard.
The use of Ceraphire pressure sensors may help plant operations and maintenance personnel realize optimum process performance and stability in process applications by identifying advantages that come with selecting ceramic pressure measuring cells.

It also brings awareness of enhanced performance and stability in pressure measurement to plant maintenance, quality assurance and operations personnel in order to improve their operations and the bottom line.
Proportional integral derivative (PID) control is the most commonly used control algorithm in the industry today. PID controller popularity can be attributed to the controllers effectiveness in a wide range of operating conditions, its functional simplicity and the ease with which engineers can implement it using current computer technology. This paper covers some of the PID drawbacks and how to resolve them while improving performance in current implementations through changes in the algorithm.
On September 11, 2001, America was attacked by terrorists and the United States quickly acknowledged
vulnerabilities at our airports, borders, food supply and water supply systems. Soon after, the government
required vulnerability assessments (VAs) for all municipalities with large cities required to go first. In 2002,
Madison Water Utility (MWU) in Madison, Wisconsin, underwent its VA and saw a need for video cameras at
many locations, including 32 remote sites.
Two obstacles stood in the way of Madison meeting this need:
- Technology--whose cameras, network and communication system? How can video work with our SCADA system?
- Money-- who will pay to protect Madisons water supply?

Ethernet is penetrating ever deeper into distributed control systems to provide real-time control with direct connectivity to a wider range of devices while the insatiable demand for speed (e.g. 10/40/100G) from commercial applications are driving continual advancements in Ethernet technologies.
This expanded deployment of Ethernet in manufacturing has triggered convergence of disparate network technologies over a single Ethernet-based infrastructure, and this trend has left the controls engineer with new and more choices regarding how to specify and install the necessary network physical infrastructure. It becomes clear that network convergence continues unabated, thereby generating new and expanded network physical infrastructure options.
With the rising cost of energy, the use of variable frequency drives (VFDs) is growing at an increasing rate. By optimizing the frequency of a three-phase alternating-current (AC) induction motors voltage supply, a VFD controls the motors speed and torque while providing energy savings. And, these energy savings can be quite substantial 20% or more making VFDs a green solution as well as a wise money-saving investment.
However, in order to be truly green, a technology must be sustainable as well as energy efficient. Yet the currents induced on motor shafts by VFDs can wreak havoc with motor bearings, dramatically shortening motor life and severely diminishing the reliability of systems. To mitigate these currents and realize the full potential of VFDs, a cost-effective method of shaft grounding is essential.
