Managing Infrequent Operational Procedures Is Critical to Safe Process Manufacturing

For all the sophisticated automation in process manufacturing environments, there is one area where operators still take manual control in many facilities: procedures for infrequent operations. When it is time to start up a unit, make a grade change, adjust to a new feedstock, or make any number of specific adjustments to the process—operators often […]

How to Achieve Optimal Web Tension Control

Tension controls are crucially important, both for the runnability of the machine and for the overall quality of the product. However, this control is quite often executed imperfectly or even incorrectly because of poor design or engineering. Many times the selected components themselves are good, but they are still incorrect for the specific application, or […]

Why Do Most Vessel Control Loops Need the Reset Time Increased by Two or More Orders of Magnitude?

The proportional, integral, derivative (PID) controller is the common key component of all control loops. Basic control systems depend upon the PID to translate the measurement signals into set points of secondary loop controllers, digital valve controllers, and speed controllers for variable frequency drives. The success of advanced control, such as model predictive control, depends […]

Where Do Humans Fit in the Factory of the Future?

Much has been written and forecasted about the various impacts of technologies on humans: work, pleasure, productivity, and behaviors. The exponential growth of technical tools and their explosive applications to our lives have been nothing short of astounding. These have created an equally dramatic increase in new jobs with required skills. Organizations seek to fill […]

How to Integrate Industrial and Information Networks

The benefits of converging industrial and information networks with a validated secure architecture based on standard Internet Protocol (IP) technologies are well established. The benefits include greater connectivity and integration across plants, easier data sharing across the enterprise, and better visibility into real-time operations. Bringing together information technology (IT) and operations technology (OT) networks is […]
