Evolving response beats mutating cyber threats

Dynamic cooperative response by suppliers and users can mitigate cyber threats and attacks

Jim Montague, executive editor, Control
HUG day3 Cyber

Cybersecurity threats and attacks are always mutating, so protective measures must be equally vigilant and adaptive. Luckily, process manufacturers and other industrial organizations have many partners, such as Honeywell Process Solutions (HPS) and Intel, who can help them coordinate protection of their systems. A living example of this cooperation on cybersecurity was delivered today by Raj Samani, CTO for Intel Security's Europe, Middle East and Africa division, and Eric Knapp, director of cybersecurity solutions and technology for HPS, at the 2015 Honeywell User Group Americas conference in San Antonio, Texas. They presented "Botnets and Zombies—Managing Risk in a…

Beginner's guide to differential pressure level transmitters

By David W. Spitzer

The importance of level measurement cannot be overstated. Incorrect or inappropriate measurements can cause  levels in vessels to be excessively higher or lower than their measured values. Low levels can cause pumping problems and damage the pump, while high levels can cause vessels to overflow and potentially create safety and environmental problems. Vessels operating at incorrect intermediate levels can result in poor operating conditions and affect the accounting of material. Learn more.

Controllers: Direct vs. reverse-acting control

By Bela Liptak

Valve failure position is determined by safety considerations. If, in case of failure, you want your column to go on full reflux, your selection where the reflux control valve is fail-open, and net overhead control valve is fail-close, is right. Assuming that the valve actuators are spring-operated pneumatic ones, and assuming that you define "failure" as the loss of air supply, the spring will act to open a fail-open (FO) valve and to close a fail-closed (FC) valve, regardless what the controller actions are.

Robot pilots? Improving level detection reliability

Flying with a robot at the controls could be a tough sell; How many level gauges do you need for an accurate measurement?

By Bela Liptak

Q: Pilots or robots in the cockpit? You have written many times about the potentials of automation in improving air transportation safety and efficiency. Besides writing your columns, have you done anything about that? Is ISA, NASA or anybody else taking advantage of our automation and control…

Essential Feedforward Control and Operator Interface Tips

All feedforward control systems can be reduced to a common form that enables a better understanding and recognition that leads to the best performance and the best interface for the operator. For “smart controls” to be fully appreciated and utilized, the operator needs to know what is going on and how to participate. Here we show how to make the advantages of feedforward control more achievable and recognizable.
