The Characteristics of PID controllers
This tutorial presented by the University of Michigan's School of Engineering will show you the characteristics of proportional (P), integral (I), and derivative (D) controls, and how to use them to obtain a desired response.

On-line alarm auditing: A tool for greater efficiency
It seems like everyone is talking about alarm system rationalization or re-engineering projects these days. But sometimes these rationalization projects have trouble getting off the ground. This White Paper describes a way to justify the alarm rationalization project by installing an on-line alarm auditing tool.
Dual-homing: Bringing redundancy to the edge of the network
In the past, the choices for redundancy for edge-of-the-network devices were too limited, too expensive, or too complicated to be considered in most industrial systems. This White Paper, however, contends that today's dual-homing technology can changes all that. Read how.
Economic justification for alarm system reengineering
Restoring your alarm system to a useful state can eliminate duplicate and nuisance alarms, and ensure that the necessary alarms are properly prioritized and documented. This White Paper presents a model for justifying an alarm system reengineering project, and provides two case studies showing the application of the model.

Process control, production control and alarm management
When you lift your hand to catch a ball it is very unlikely that your brain actually formulates or solves the equations of motion in working out when and where to place your hand to catch the ball. Its much more likely that you use, unconsciously, something thats much more akin to the geometrical methods underlying the all-new Geometric Process Control Technology described in this article.
System protection profile for industrial control systems
The first draft of the System Protection Profile for Industrial Control Systems, designed to present a cohesive, cross-industry, baseline set of security requirements for new industrial control systems, is available for download and review.
Patch management for control systems
This guideline provides suggestions for an effective cyber security patch management strategy for control systems, addresses potential risks that can apply to some electricity sector organizations, and provides practices that can help mitigate the risks.
Alarm reduction using Exaplog: A case study
By reducing the number of alarms and enabling the audible alarming function of its control system, GFS Computing was able to restore audible alarming on half of its operator consoles, leading to tangible, measurable improvements in productivity, safety, and cost-reduction.
The link between automation KPIs and enterprise KPIs
This White Paper presents case studies that demonstrate how improved control system KPIs directly drive improved corporate KPIs, and how managing these factors can ensure better performance of the long-term measures.
Specifying industrial fieldbus networks for automation
Automation designers face many challenges and tradeoffs in the development of a successful network solution. This White Paper discusses the necessary choices in selecting a network technology appropriate for various specific applications.
Shift your focus from analysis to optimization with AMCT
This White Paper shows how the application of Active Model Capture Technology (AMCT) by a manufacturing plants problem-solving personnel reduces time wasted, and helps to focus the effort of these problem-solvers who must keep the process running at its best.
Security for critical infrastructure SCADA systems
This "special to the web" White Paper provides a non-technical overview of critical infrastructure SCADA security and gives a background on SCADA systems and the history of critical infrastructure concern.
Securing known SCADA vulverabilities
This special to the web briefing report from the Office of the Inspector General evaluates the impediments and barriers that prevent water systems and other Power-Gen plants from securing known SCADA vulnerabilities.
Initiatives in strategic alarm management
The inability to effectively manage control system alarms has been a long tolerated issue in the continuous process industry. This White Paper provides detail behind a solution to the total alarm management problem that takes into account the key elements and directly targets the real issues.

Process, instrument and plant engineers are challenged continuously by productivity and plant operating efficiency objectives as well as ensuring plant compliance with an ever expanding list of regulations.
Purge and pressurization is an alternative hazardous location protection concept that allows lesser rated equipment to be used in hazardous areas by segregating the equipment from the hazardous material.
Today's utilities operate in highly productive business environments that are very competitive. As such, they need to comply with stringent regulatory requirements to prevent downtime that may negatively impact customers. A slight failure of equipment can translate to immediate consequences from both a financial and safety perspective.
This next in Control's Essentials series, "Essentials of the Connected Enterprise" provides industrial automation professionals with up-to-date information on the advances in communications and computing technology.
Find out how a full featured embedded HMI for machines can improve operational agility and increase manufacturing performance with less effort. Machines delivered without a full featured HMI can cause operational issues such as lower operational agility, inability to continuously improve, decreased predictability, higher risk and increased total cost of ownership. A full featured embedded HMI can alleviate these issues by providing better information on the plant floor, along with greater connectivity and fast integration into your production system. Download the white paper to get more details on the new Wonderware solution to these problems.
