User-defined instructions (UDIs) let engineers write logic once and reuse it across many components, eliminating tedious copy-paste duplication. Any updates to a UDI definition automatically propagate ...

Programmable logic controllers (PLCs) and programmable automation controllers (PACs) are industrial computers constructed and adapted for manufacturing environments. These computers are the brains of ...

In the process of industrial automation, industrial robots are widely used in complex operations such as welding, assembly, and handling. The dynamic response performance under time-varying load ...

Ensures safe, stable, and optimized refinery operations through design, configuration, maintenance, and governance of control, safety, and automation systems.

The Practical Series Automation Library (PAL) is a library of software modules and templates that have been developed for the Siemens Simatic S7-1500 range of controllers (and to a lesser extent the ...

The 18 XPlanar movers on the assembly machine built by Automation NTH travel over 18 motor tiles to present the blood test kits to the various reagent filling ...

Imagine a 9-year-old lad making a crystal ra­dio set with his dad, an electrical engineer at Allen-Bradley for more than 30 years. Nearly half a century later, that lad is looking back on a successful ...

Abstract: We developed an UML-State-charts Object Oriented Design Pattern for PLCs IEC61131-3. This PLC UML-State-chart Design Pattern aims to explore the advantage of Object Oriented Programming by ...

A Programmable Logic Controller is “a small industrial computer originally designed to perform the logic functions executed by electrical hardware (relays, switches, and mechanical timer/counters),” ...

Threat groups who target operational technology (OT) networks have so far focused their efforts on defeating segmentation layers to reach field controllers such as programmable logic controllers (PLCs ...
