Cloud Computing and the Industrial Internet of Things

Over the last decade, cloud service providers have improved technology, particularly data security and integrity. These remain the top concern of many manufacturing businesses, but as improvements are rolled out, more and more companies are adopting cloud solutions. 


Automation Issues and Energy Usage in Environmental Extremes

Automation Issues and Energy Usage in Environmental Extremes

As summer heat continues to scorch the northern hemisphere, manufacturers face potential equipment damage and downtime. Learn about the ways extreme heat can damage automated equipment and systems. 


Understanding Differences Between Power and Ground Side Switching

Understanding Differences Between Power and Ground Side Switching

Learn about power side and ground side switching and how designing these circuits to have predictable failures from the beginning helps in system maintenance and troubleshooting.


What is Firmware, and Why is PLC Firmware Important?

What is Firmware, and Why is PLC Firmware Important?

Inside a controller, code is interpreted into the binary signals that influence input and output signals, flags and registers, and even the communication of network signals. This is the job of firmware.


Interrupting Dangerous Current Flow: Fuses vs. Circuit Breakers

Interrupting Dangerous Current Flow: Fuses vs. Circuit Breakers

Fuses and breakers are some of the most common safeguards to prevent electrical shock and fires. Learn about these two pieces of industrial equipment and the difference between slow blow and quick blow responses.


How to Program a Robot: Industrial Robotic Arm Coding Basics

How to Program a Robot: Industrial Robotic Arm Coding Basics

The world of manufacturing is filled with robots, but beginners are still always faced with key questions, starting with perhaps the most basic: how do you program industrial robots?


Understanding Centralization vs Decentralization of PLCs

Understanding Centralization vs Decentralization of PLCs

Centralized control systems are often seen as outdated compared to decentralized systems; however, both have their advantages and disadvantages when it comes to choosing which one to use in manufacturing. 


CTRL F3: Factory Explosion Field Study

CTRL F3: Factory Explosion Field Study

The CTRL F3 series reviews field studies and failures in the field focused on control fails, fixes, and facts. This article covers an explosion at an industrial sawmill.


Negative Effects of Grounding (Earthing) a DC Power Supply

Negative Effects of Grounding (Earthing) a DC Power Supply

DC voltage systems exist to provide controllers and field devices with stable power, but it is not always clear when these systems should be bonded with the earth ground of the AC line voltage supply.


Understanding PLC Program Commands: Math Instructions

Understanding PLC Program Commands: Math Instructions

We will show you how to use common math functions from two popular PLC programs—Rockwell Automation's Studio 5000 and Automation Direct Productivity Suite. 


Advanced Scaling Techniques for PLC Analog Quantities

Advanced Scaling Techniques for PLC Analog Quantities

Configuring analog signals into usable digital quantities is accomplished by scaling function inside the PLC, which, along with analog signal wiring, is important to understand.


Understanding PLC Program Commands: Up and Down Counters

Understanding PLC Program Commands: Up and Down Counters

Counting up and down are commonly required functions in PLC lagger logic programs for tracking inventories, placement patterns, and gaining informational insights about machine performance statistics.

Designing an obsolescence mitigation plan to detect and solve mitigation risks before they occur is key to avoiding costly downtime and a potential catastrophe in control environments. 


Understanding PLC Program Commands: One-Shots

Understanding PLC Program Commands: One-Shots

Many PLC commands are well-known to programmers, including contacts, coils, timers, and counters. But a less-common instruction is the one-shot, capable of harnessing the incredible processing speeds in a CPU.


Clarifying Misconceptions About Theoretical vs Physical Circuits

Clarifying Misconceptions About Theoretical vs Physical Circuits

Control engineering is integrally woven together with electricity and electrical circuits. Even so, sometimes the most basic scenarios become misunderstood through lack of training or experience.


Obsolescence in Control Systems - Disaster or Opportunity?

Obsolescence in Control Systems - Disaster or Opportunity?

One of the most considerable risks in aging control environments is that eventually, spare parts become obsolete and unavailable, and the lack of an upgrade plan can turn a simple failure into a catastrophe.
