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.


Working With Legacy Systems—Why Use Serial to Ethernet Converters?

Working With Legacy Systems—Why Use Serial to Ethernet Converters?

One common challenge when working with legacy control systems is establishing communication with old devices that use old protocols like RS232 and RS485. Learn about the importance of converting from serial to Ethernet.


Configuring a Network With Pneumatic Valve Manifolds

Configuring a Network With Pneumatic Valve Manifolds

There are many distributed fieldbus capabilities for valve manifolds that can save on network overhead and wiring. In this article, we will look at PLC programming of fieldbus manifolds highlighting Festo's CPX layout.


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.


Controlling Hydraulic Devices with Open and Closed Loop Systems

Controlling Hydraulic Devices with Open and Closed Loop Systems

What if you could control the end position and the speed of a hydraulic actuator accurately with just a simple signal? Some systems use simple open/close valves, but others require far more precision.


The Cat’s Out of the Bag - Demystifying Network Cables

The Cat’s Out of the Bag - Demystifying Network Cables

What’s the difference between a Cat 6 and a Cat 6a cable, anyhow? Ethernet cables must meet certain performance standards, and these standards can be quite confusing at first glance.

Our Control Automation engineering staff got the chance to visit a commercial farm in North Dakota and learn the hardware and software making these huge automated tractors ready for high-tech ‘field’ work.


Dynamic Braking Resistors for Motor Control Applications

Dynamic Braking Resistors for Motor Control Applications

Large DC and AC motor drives often provide terminals for installing a braking resistor. What are these resistors, and how do they slow down a machine? What hazards and cautions must be considered?


Introduction to Safety Relays

Introduction to Safety Relays

Redundancy and safety are often seen together in industrial safety systems. Safety relays monitor emergency devices to switch contacts based on status - but what makes them different from normal relays?


Info Byte: Preventing Relay Burnout with Flyback Diodes

Info Byte: Preventing Relay Burnout with Flyback Diodes

Inductive loads, such as solenoids and contactors, can cause arcs and failures back into electromechanical switching devices, causing costly downtime. The solution is cheaper than you think.
