With the advancement of computer and data transmission technologies, systems formerly reserved for the office environment are now critical components of the manufacturing floor. The demands of factory automation, in addition to computer hardware and software, have brought the wire and cable networking products that interconnect these technologies into the industrial setting as well.
With the vast differences between an office and an industrial environment, networking cables such as gigabit Ethernet have had to adapt to these harsh new surroundings, not only from a physical perspective but from a performance perspective as well, in order to function reliably.
This white paper discusses the constructional differences between standard Gigabit Ethernet and the specifications required for similar cables utilized in an industrial manufacturing environment. Additionally applications for these ruggedized designs are also reviewed.09/26/2012
This paper describes the application of an advanced model predictive adaptive controller to the problem of batch reactor temperature control. Although a great deal of work has been done to improve reactor throughput using batch sequence control, the control of the actual reactor temperature remains a difficult problem for many operators of these processes. Temperature control on these systems is difficult for conventional Proportional-Integral-Derivative (PID) controllers because the response is characterized bynan open loop integrator with long delay and time constant. Temperature control is important as many chemical reactions are sensitive to temperature for formation of desired products and reaction rates can be highly temperature dependent. The applications discussed in this paper include a PVC reactor and an Ethoxylated fatty acid reactor. In each case, the variability of the reactor temperature was reduced by 60% or more. Improved temperature control permitted operation at higher reaction temperatures with higher sustained feed rates of reactants and catalysts while remaining within product temperature limits. Batch cycle times were reduced by as much as 35% due to the higher sustained reaction rates. The applications demonstrate the attractive economics for optimization of batch reactors with model predictive controls and highlight the opportunity for tremendous improvements in batch consistency, reduced batch cycle times, and improved productivity.08/25/2008

In today's manufacturing environment, there is an urgency to increase operating efficiencies, and to do it quickly. One area of improvement that can produce immediate results is reducing energy consumption. It's good for the environment and it's good for the bottom line. "Energy management," therefore, has become a common best practice, but there is more there than meets the eye. Typically it implies rigorously modeling all or a major portion of the plant, coupled with the use of real-time optimization technology. While this approach has been used successfully, there are other simpler, faster options for reducing energy consumption in a manufacturing plant. Learn what these options are.03/25/2010
Advances in Low Voltage Motor Control Center (MCC) Technology Help Reduce Arc-Flash Hazards and Minimize Risks
Selecting the right MCC equipment leads to improved plant safety, helping protect people and capital investments.
Measures to increase equipment and personnel safety in manufacturing are reflected in new approaches and technologies designed to help minimize the risk of workplace dangers. One rapidly growing area of focus is reducing the potentially serious hazards associated with arc-flash events. This white paper examines the causes of arc flash, discusses the standards guiding arc-flash safety and details the role arc-resistant motor control centers (MCCs) play in helping contain arc energy. It also highlights the key features of an effective arc-resistant MCC design.
Managing safety hazards and reducing risks are top priorities for manufacturers across all sectors of industry. With a multitude of potential dangers and new ones continuously emerging, companies must be diligent in their ongoing efforts while considering new approaches and technologies to improve plant safety. One rapidly growing area of focus is implementing techniques and practices designed to reduce hazards and minimize risk for workers who must enter an area with an electrical arc-flash potential.04/07/2010

It's now time to upgrade to a new HART Communicator. Your old hand held HART Communicator is obsolete and receives limited support. You shop around and find that it costs between $3000 and $7000 for a new hand held HART Communicator. A Google search reveals a PC based alternative. Will the PC alternative perform as required? What should you look for?
The PC based HART Communicator has been around for many years, but until recently it has not been able to replace the hand held HART communicator. The main reason is that it could not communicate at the DD level with all the devices in the DD library. Recent developments have eliminated that problem and now is a good time to review the capabilities of a PC based HART Communicator.12/01/2009
Alarm and event analysis has long been used for improving process operation. However since alarms are usually generated and displayed based on physical equipment, alarm analysis has been difficult to perform on a batch basis. In this paper, we focus on the interrelation of alarm/message notification and operator reaction in a batch process and analyze them systematically according to S88.01 Models and Terminology. Balance patterns of alarm/message notification and operator reactions are visually analyzed. Batch based analysis is done by grouping and filtering alarm and event data by master recipe, procedural hierarchy, and batch unit. This makes it easy to find and improve spurious alarms and inefficient operator habits. In a brief experience in a pharmaceutical plant, spurious alarms have been reduced by approximately 30% and smoother operation procedures have been implemented.08/28/2008

AMS2750D Temperature Uniformity Surveys using TEMPpoint.
Industrial process furnaces and ovens require uniform temperature and heating; This is critical to repeatable product performance from batch to batch. These furnaces require periodic inspection for temperature uniformity.
Electronic and Mechanical Calibration Services, Millbury Massachusetts characterizes temperature uniformity in industrial furnaces and ovens for their customers. This is accomplished by measuring temperature in several locations throughout the furnace and monitoring temperature with thermocouples over time according to AMS2750D specifications.
The customer previously used chart recorders which require constant monitoring while the survey is running. Surveys can run anywhere from 35 minutes to several hours long depending on the industry specified requirements. With the TEMPpoint solution the operator can set it up and let it run unattended, freeing them up to multitask their time and work more efficiently. The shipping TEMPpoint application required very little modification using Measure Foundry and now fulfills customer's requirements.01/06/2010
