Future Engineers Benefit from ISA Student Sections

In a prior blog post, I talked about how ISA student sections present opportunities for members to shape future generations of automation professionals. This article focuses on the benefits students receive from active participation in section activities. Given the difference in levels of education, one might conclude that the student sections at Francis Tuttle Technology […]

How to Use 4G LTE Wireless Technology to Secure Industrial Automation and Control Systems

Supporting business needs by improving defense-in-depth cybersecurity for industrial automation and control systems (IACSs) is a key challenge today. For example, oil, gas, and water plants need to access scattered and remote areas and wells, but cybersecurity can be a major challenge, which may require physical security and cybersecurity protections and controls. Therefore, wireless technology, […]

Flowmeter Primer: Two-Wire Coriolis and Electromagnetic Transmitters

Two-wire transmitter technology came about from an agreement among various instrument suppliers in the 1950s to standardize on 4–20 mA current loops as a means of sending a flow, temperature, pressure, or similar process signal back to control and monitoring systems. In the 1980s, HART was added to the 4–20 mA signal, providing additional calibration […]

How to Link HAZOP and LOPA to Calculate a Safety Instrumented System

Although a hazard and operability (HAZOP) analysis identifies failure events or upsets and the severity of the outcomes by engaging knowledgeable plant personnel, the process typically provides only qualitative information about event frequency and mitigated frequencies. This helps plants make decisions for safety improvement, but does not provide the detailed information necessary for a safety […]

How to Use Life-Cycle Dynamic Simulation to Optimize Process Plant Operations

The oil and gas production explosion is driving the renaissance of the chemical and process industries. With low-cost natural gas comes low-cost feedstock for many chemical compounds, in the form of ethane, propane, and butane, economically boosting the chemical industry. The American Chemistry Council released a report predicting capital investment of $72 billion in more […]

How to Use the Cloud to Store and Distribute Manufacturing Data

Cloud-based human-machine interface (HMI) software, databases, and historians are ideal gateways to deliver practical and actionable machine, manufacturing, and plant information to those who need it. Harnessing cloud capabilities to harvest data from plant floor automation systems and then distributing this data to users is a powerful combination that can save money, speed implementation, enhance […]
