Using IIoT for a more energy-efficient pump environment
Learning Objectives IIoT project uses wireless communications and sensors to analyze pump energy use. Energy maintenance savings are among expected results. Process manufacturers with many pumps could benefit from pursuing a similar project. The economics of improving pump energy consumption are compelling, and a case study shows how significant savings can be achieved.
Method finds hidden warning signals in collected measurements Original
MIT researchers have developed a deep learning-based algorithm to detect anomalies in time series data. Courtesy: MIT News When you’re responsible for a multimillion-dollar satellite hurtling through space at thousands of miles per hour, you want to be sure it’s running smoothly. And time series can help. A time series is simply a record of a measurement taken repeatedly over time. It can keep track of a system’s long-term trends and short-term blips.
Top 5 Control Engineering Articles Dec. 14-20, 2020
The top 5 most read articles online, from Dec. 14-20 for Control Engineering covered migrating legacy PLC programs to modern PLC hardware, system integrators reducing maintenance costs, flowmeter testing and calibrating challenges, and more. Links to each article below. 1. Migrating legacy PLC programs to modern PLC hardware Zero downtime is a requirement for many water/wastewater processes, often necessitating upgrading legacy automation by migrating existing code 2.
Data flow, alarms, simulation, cybersecurity, robotics
By Mark T. Hoske December 20, 2020 Automation, controls, and instrumentations are critical, innovative, interesting and productive, and Control Engineering offers information on Boeing’s automation adjustments to its 737 Max and developments on data flow, alarm design, digital twins and simulation efficiency, cybersecurity and robotic programming, among others.
Benefits of an alarm management philosophy
Learning Objectives Alarm management is acknowledged as a need, but how it is managed is not often addressed. Too many alarms on the manufacturing floor can cause confusion for operators. The need for alarm management is tied into the level of automated and manual processes on the manufacturing floor. Alarm acknowledgement is a widely accepted industry practice, but the reason why we apply alarm acknowledgement is a question not often asked.
Replacing seven SCADA systems with one Original
When we’re travelling, we all want to move through airports as quickly as possible. We want that for our bags too. That’s why the Greater Toronto Airports Authority (GTAA) launched its ambitious, $1.5 billion Baggage 2025 program. GTAA operates Toronto Pearson International Airport, and it had a strong vision for improving Toronto Pearson’s baggage handling system.
How RFID improves machine performance, safety
Learning Objectives Review methods for controlling and monitoring how machines operate and who controls them. See how radio frequency identification (RFID) is a passive tag system, but it can be used in many industries and applications. Learn how many RFID scanners are designed to work in harsh environmental conditions. Automated equipment and machinery can incorporate many ways for users to monitor and control operation, such as with buttons, switches, and touchscreens.
Control system connectivity update
Digitalization requires communication hubs, a role well-suited to PLCs and HMIs. Many industrial plants and facilities are executing asset digitalization projects by incorporating Industrial Internet of Things (IIoT) elements and implementing other Industry 4.0 initiatives. A key enabler for these efforts is connectivity between field devices, such as sensors and instruments, and higher-level computing platforms. Connectivity usually is via company intranets and the Internet.

Finding HMI Performance for the Long Run
By Linda Htay, IDEC Corporation Equipment operators and maintenance personnel rely on robust control systems, and a key method for interacting with these systems is through human-machine interfaces (HMIs). Users must be able to visualize the available information, and issue selections and commands as required. Therefore, most HMIs have matured to provide a comprehensive suite of display and control objects that interface easily with underlying control platforms.
