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.


Data Flow Tutorial With Mage.ai | Part 2: Initializing the Software

Data Flow Tutorial With Mage.ai | Part 2: Initializing the Software

Data pipelines are software services that progress the data from source to storage, hopefully without too much programming complexity. In this article, we begin by initializing the mage.ai 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.

Create Your Own IIoT Tech Stack Project | Part 8: Final - Data Dashboard

In this final installment of the IIoT tech stack project, learn how to design the customer-facing dashboard or observability platform using the data acquired from the MQTT client device.


There’s This Thing Called ‘Skin Effect’ in Wires: What Does it Mean to You?

There’s This Thing Called ‘Skin Effect’ in Wires: What Does it Mean to You?

Current flow in wires is often modeled with a perfectly circular cross-section, with the size of the wire being responsible for the maximum current. This is true, but there’s more to the story.


Understanding Delta-Wound Three-Phase Motors for Industrial Applications

Understanding Delta-Wound Three-Phase Motors for Industrial Applications

There are two types of winding designs inside three-phase industrial motors: Wye and Delta. Although the motors and connections look similar on the outside, this article discusses the internal construction for Delta wound motors.


Using Loop Powered Isolators to Solve Ground Loop Problems

Using Loop Powered Isolators to Solve Ground Loop Problems

Many signal sources and process transmitters do not include isolation, which can cause problems when the instruments are at different locations. A loop powered isolator is often the solution.
