Advanced Regulatory Control Perspective Tips

Advanced regulatory control seeks to incorporate knowledge of process dynamics, disturbances, constraints, and objectives to increase process efficiency and capacity. The PID power and flexibility enables an incredible spectrum of creative opportunities to achieve these goals.

A wake-up call to ignoring cyber threats – PG&E indicted on criminal charges

April 1st, a federal grand jury indicted PG&E on 12 counts of knowingly and willfully violating the federal Pipeline Safety Act leading to the San Bruno pipeline rupture. As San Bruno was a control system cyber incident, the cyber security implications include the following.

IEC Safety Standards (IEC 61508) Help

Functional Safety standards continue to generate significant interest and in many cases questions in the automation industry. The Functional Safety standards are more commonly known as IEC 61508, IEC 61511, and ISA-84. The IEC has a web site to support questions on these documents.

What Happens When You Fail to Calibrate Your Flowmeters?

A flowmeter that is not measuring properly can cause many problems. In a custody-transfer application involving rude oil or natural gas, even the smallest error can cost a customer millions of dollars a year.

Speaking at Palo Alto Networks Ignite Conference

I will be speaking April 1st at the Palo Alto Networks Ignite Conference on “Addressing the Most Pervasive Challenges in ICS Cyber Security”.

ICS Cyber Security – where is the American Society of Mechanical Engineers (ASME)

The March 2014 issue of ASME’s Mechanical Engineering magazine had an article entitled "The Internet of Very Big Things". The article focused on the productivity and safety benefits of connectivity, including to the Internet. The discussion on security was either not correct or misleading.  This is not the first time...

Who Is to Blame for Our Control Systems' Vulnerability?

Do we really need to have open systems and risk the cybersecurity of our control systems and plants, or can we do something to ensure the safety of our industrial networks?

Deferral of ICS Cyber Security Conference (Weisscon)

Joe Weiss believes there is a significant need for a cybersecurity conference from the perspective of the control systems engineer that focuses on the impacts of electronic communications on system performance, reliability and safety.

Cascade Control Recommendation Tips

Given that cascade control loops are everywhere without much consideration as to dynamic requirements, what can we do to make the implementation effective? Here are some specifics by the way of detailed recommendations on the sequence, speed, and setup for tuning PID and digital valve controllers.

ICS Cyber Security Lecture at Naval Postgraduate School

I have been invited to give a lecture on ICS Cyber Security at the Naval Post Graduate School April 3rd in Monterey on control system cyber security. The presentation will be similar to my presentation at West Point.
