A Better Fit: Comparing Electrical Systems vs. Pneumatic Systems

A Better Fit: Comparing Electrical Systems vs. Pneumatic Systems

Knowing what kind of control system to use: that’s a question that must be answered before setting up the factory floor. Why would someone choose pneumatic over electrical controls?


Data Model and Functionality of Utility Data Warehouse | UDW Part 1

Data Model and Functionality of Utility Data Warehouse | UDW Part 1

Storing data long-term for recording and reporting purposes is the job of the utility data warehouse, quite different from data-collection processes that optimize systems and predict failures.


How Do You ‘Megger’ a Motor? Understanding Motor Insulation Resistance

How Do You ‘Megger’ a Motor? Understanding Motor Insulation Resistance

Within motors, two very different types of resistance are evident. The resistance of the windings is measured with a normal multimeter. But what is insulation resistance, and how is it measured?


Electrical Drawings, Schematics, and Wiring Diagrams: How to Read Them

Electrical Drawings, Schematics, and Wiring Diagrams: How to Read Them

In order to trace control system problems to the core, the ability to read and interpret various resources, from facility-level diagrams to machine-level wiring layouts, is critical.


How to Convert Numbers: Binary, Decimal, and Hex Systems

How to Convert Numbers: Binary, Decimal, and Hex Systems

Converting different numbering systems is quite common in PLCs and structured text codes. Why? Because people read decimals. Computers read binary. Processors read sets of bits. Not so simple.


What is a Soft Start? Reducing Start-up Load on Motor Circuits

What is a Soft Start? Reducing Start-up Load on Motor Circuits

Controlling the startup of a motor not only reduces the wear on the motor, but eases the burden on the electrical supply, reducing infrastructure demands and the running cost of industrial loads.


What is a Fuse? The Skinny On Overcurrent Protection

What is a Fuse? The Skinny On Overcurrent Protection

Protecting equipment and personnel from overcurrent dangers, like sparks and fires, is the primary job of the humble fuse, one of the most basic, yet critical of all safety devices.


Star-Delta Wiring for Reduced Voltage Starting of 3-Phase Motors

Star-Delta Wiring for Reduced Voltage Starting of 3-Phase Motors

Digital controls like VFDs and soft starts have advantages by elongating start time, but simple strategies for starting motors with a reduced current draw, like star-delta (or wye-delta) are common.


PLC Naming Conventions: How Should I Write My Tag Labels?

PLC Naming Conventions: How Should I Write My Tag Labels?

It’s important to consider your PLC tag naming convention when using different styles. Learn when and why you might even use more than one, depending on the circumstances and scope of your project.


What is a Circuit Breaker?

What is a Circuit Breaker?

We depend on circuit breakers all the time, even when you have a day off or work from home. These overcurrent protection devices keep machines running safely, reducing the risk of fires and arcing.


Handling of Power System Data | Indications, Counters, and Data Flags

Handling of Power System Data | Indications, Counters, and Data Flags

For large process systems, learn how the location of data indication and flag processing can increase or decrease the burden on computers at the device, RTU, or main computer level.


Understanding the 17xx | Your Rockwell/Allen-Bradley Hardware Encyclopedia

Understanding the 17xx | Your Rockwell/Allen-Bradley Hardware Encyclopedia

Rockwell Automation’s Allen-Bradley control hardware catalog has long included many series that start with 17xx, but what are these lineups, and what function do they serve?


What is a Variable Frequency Drive (VFD)?

What is a Variable Frequency Drive (VFD)?

When we need to change the speed of an industrial motor, whether to control a process or save energy costs, we turn to the variable frequency drive, better known simply as a VFD.


Strain Gauges: Real-World Considerations and Typical Applications

Strain Gauges: Real-World Considerations and Typical Applications

In this article, we will explore real-world considerations for strain gauge performance and typical applications. We’ll be talking about foil and wire strain gauges, but ignoring semiconductors.


Info Byte: What Do NC and NO Mean?

Info Byte: What Do NC and NO Mean?

Some terminology, like 'normally open' and 'normally closed' switch contacts, is common throughout industry but can still be confusing, misleading, or even hazardous if not properly understood.


Data Flow Tutorial With Mage.ai | Part 3: Connecting to Google Sheets

Data Flow Tutorial With Mage.ai | Part 3: Connecting to Google Sheets

In this article, we will explore the inbound integration to the mage.ai pipeline, connecting to the spreadsheet data source using the Google Sheets API through a JSON credentials file.


PLC Input and Output Module Troubleshooting Techniques

PLC Input and Output Module Troubleshooting Techniques

When inputs or outputs stop working, the equipment fails to respond and money starts slipping away. Dive into the concept of troubleshooting I/O without ever opening the PLC software.


Identifying and Troubleshooting Pressure Changes in Fluid Systems

Identifying and Troubleshooting Pressure Changes in Fluid Systems

Pressures are always rising and falling in fluid systems. Sometimes the changes are extreme and lead to damage. What causes problematic pressure changes, and how can you trace them to their source?


Handling of Power System Data: Engineering Limits and Data Currency

Handling of Power System Data: Engineering Limits and Data Currency

Power systems rely on meaningful data, as do most other processes. Within SCADA environments, individual data points are tracked, compared to limits, and evaluated to obtain current readings.
