The Beginner’s Guide to Automation: Making Sense of Prox Sensors

The Beginner’s Guide to Automation: Making Sense of Prox Sensors

Detecting objects is the first field-level task that must be considered before any feedback-based control can happen. Choosing from among the nearly unlimited proximity sensors can be challenging!


How-to: Programming Discrete I/O With a Koyo DirectLOGIC PLC

How-to: Programming Discrete I/O With a Koyo DirectLOGIC PLC

Learn how to use DirectSOFT6 to program discrete I/O functions in a Koyo DirectLOGIC PLC. Although these PLCs are older, they are found in many existing automation installations.


Setting IP Address and Networking Parameters on a PowerFlex VFD

Setting IP Address and Networking Parameters on a PowerFlex VFD

Parameters control the operation and command sources for VFDs. The PowerFlex series from Rockwell Automation is no exception. Learn how to adjust the parameters for networking and IP configuration.


What Is a ‘Valve Spool’ and How Do Spool Valves Work?

What Is a ‘Valve Spool’ and How Do Spool Valves Work?

Fluid control valves rely on the opening and closing of internal passageways to direct the flow of power. But what do they look like inside, and how do these ‘valve spools’ actually work?


Techniques for I/O Mapping in PLC Programs

Techniques for I/O Mapping in PLC Programs

I/O mapping is the process of converting raw input and output data into specific tags, but how can we find a method for mapping I/O that is both efficient and scalable?


Understanding Industrial Ethernet Connections: RJ45, Fiber, M12, and SFP

Understanding Industrial Ethernet Connections: RJ45, Fiber, M12, and SFP

Ethernet switches can use four different types of connections: RJ45, fiber, M12, and SFP. Understanding the difference can help with network troubleshooting, design, or alteration.


Designing a Custom Machine Alarm System: From PLC to HMI

Designing a Custom Machine Alarm System: From PLC to HMI

Creating custom alarm systems can be complicated and overwhelming, but they can also be very beneficial for equipment builders and integrators. Follow along as we build a custom alarm handling system.


Too Much Current! Breaker Curves and Overload Trip Classes

Too Much Current! Breaker Curves and Overload Trip Classes

We know what a circuit breaker is meant to do: stop the flow of electricity in case of a fault or failure. But just like fuses, breakers and overloads respond differently depending on the load.


What is a Servo, and How do Servo Motors Work?

What is a Servo, and How do Servo Motors Work?

Servo motors are common in all kinds of motion control applications for various industries, but what are these devices, and what makes them different from standard AC or DC motors?
