B&R Industrial Automation Hardware and Software

B&R Industrial Automation Hardware and Software

B&R is a control system manufacturer less heard of than some of its bigger competitors, Rockwell and Siemens, however their PLCs, lineup of motors, and product offerings with Automation Studio make B&R a leader in industrial innovation.


Preventing Failures in High-Temperature Manufacturing Processes

Preventing Failures in High-Temperature Manufacturing Processes

Any machine can become a source of elevated temperature, even under regular operation. We cannot assume that temperature problems occur only based on climate conditions, and mitigation steps must be employed.


Active Power, Reactive Power, Apparent Power, and the Role of Power Factor

Active Power, Reactive Power, Apparent Power, and the Role of Power Factor

The diverse power terms in electrical generation systems include active, reactive, and apparent power, all of which lead to the introduction of ‘power factor’ effectiveness in an AC circuit.


Recreating PLC Ladder Logic in an Arduino C/C++ IDE

Recreating PLC Ladder Logic in an Arduino C/C++ IDE

​​​​​​​Arduinos have been a staple in the community of makers, students, and project innovators for many years. For many using Arduino’s IDE, there can be difficulties in translating between PLC ladder rungs and text programming.


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.


Predictive Maintenance: Defect Analysis Using Electrical Current

Predictive Maintenance: Defect Analysis Using Electrical Current

Electrical signal analysis has come to the forefront of predictive maintenance, helping to reduce downtime in industrial manufacturing by remotely identifying problems with electric motors and generators.


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.


Variable Frequency Drives: Managing Network Outage Responses

Variable Frequency Drives: Managing Network Outage Responses

Even with the most reliable networks, network outages are inevitable for a host of reasons, and managing these outages in VFD systems becomes critically important.


Contactors versus Relays - Differences and Applications

Contactors versus Relays - Differences and Applications

Although the are similarities in operating theory, relays and contactors are used in industrial circuits for different specific applications, and should not be used interchangeably.


Hysteresis - Error and Compensation in Control Systems

Hysteresis - Error and Compensation in Control Systems

Hysteresis is a term introduced in basic control system courses and listed on sensor datasheets, but the terms is not often understood, with error deriving from both the system itself as well as the sensor.


Comparing Mechanical vs Hydraulic Forces

Comparing Mechanical vs Hydraulic Forces

In honor of May the 4th, Star Wars Day, we compare the sources and applications of the two most common force-delivery systems - mechanical and hydraulic.


Up Close and Personal With Automated Ag Equipment

Up Close and Personal With Automated Ag Equipment

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.


Epson Robot Programming Example

Epson Robot Programming Example

Epson robot programming bears similarities to other industry-standard brands, but contains many unique features, including the ability to run background programs alongside the main function.


Defining Scalar and Vector Control in VFD Outputs

Defining Scalar and Vector Control in VFD Outputs

Two common methods exist for driving induction motors with VFDs - linear scalar control, which is often labeled as V/f, and vector, or field-oriented control, which can be a bit more complex to understand.


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?


Mechanisms of Linear Sensing and Linear Encoding

Mechanisms of Linear Sensing and Linear Encoding

Linear sensors use electrical means to determine their position. Common linear position sensors are resistive, inductive, capacitive, and many rely on a property called magnetostriction.


Linear Position Sensors - Control is Only as Precise as the Feedback

Linear Position Sensors - Control is Only as Precise as the Feedback

Linear position sensors are used in electrical and fluid-actuated motion devices. They allow extremely precise position, velocity, and acceleration control, and provide feedback to ensure product quality and tolerance compliance.


DC Motors - Why Are We Still Using Them?

DC Motors - Why Are We Still Using Them?

AC motors are common throughout industry - easily controlled by VFDs and without the maintenance that comes with DC brushes. So then, why are DC motors still used in certain applications?


Info Byte: What’s the Deal With Debouncing Switches?

Info Byte: What’s the Deal With Debouncing Switches?

Before digital control systems, responses were fairly slow. Push a button, and a motor contactor engaged. These days, the speed of computers introduces some new challenges but brings solutions as well.
