The middle layer, or API layer of a custom-built HMI project involves a server that can submit or receive data to and from a device, either to provide the user interface or interact with the machine.


What Does ‘Explosion Proof’ Mean, and Who Should Care?

What Does ‘Explosion Proof’ Mean, and Who Should Care?

Some workplaces are more dangerous than others, not because of the practices, but rather the products. Where do explosions occur, and what practices exist to reduce such risk for equipment and workforce?


What You Need to Know: Soft Starters for Industrial Motors

What You Need to Know: Soft Starters for Industrial Motors

Driving motors is one of the most fundamental automation tasks, but understanding and selecting the proper motor soft starter for your application may require more investigation than you thought.


Examples of Analog Signals in Control Systems

Examples of Analog Signals in Control Systems

Many articles address the wiring and implementation of analog control signals, but where are they used, and what might make them a better (or perhaps worse) decision than digital input/output devices?


Potential Problems Arising from Misuse of Motor Phase Wiring

Potential Problems Arising from Misuse of Motor Phase Wiring

Using the right motor for the right task is critical - but what happens if the motor is connected to the wrong supply? It is never recommended, but important to quickly understand symptoms of incorrect wiring.
