1. Which IEC 61131-3 programming language is best? Part 1

With so many programmable logic controller (PLC) programming languages and standards from which to choose, what is the right choice for automation and controls applications? Part 1 provides an overview and focuses on Ladder Diagram (LD) and Sequential Function Chart (SFC).

2. Top 5 VFD parameter changes explained

Programming variable frequency drives (VFDs) to fit most industrial applications require only the most basic settings to operate the motor. Understand these 5 VFD parameter changes to optimize VFD programming to fit most motor-drive applications.

3. Replacing seven SCADA systems with one

Toronto Pearson International Airport starts fast on major baggage program with new, streamlined SCADA system that serves as the heart of the ambitious project.

4. Using diamond as a metallic conductor

Normally an insulator, diamond becomes a metallic conductor when subjected to large strain in a theoretical model, which could improve solar cells, quantum sensors, optical devices and more.

5. Which IEC 61131-3 Programming Language is best? Part 2

With many programmable logic controller (PLC) programming languages and standards from which to choose, select the best language for specific automation and controls applications. Part 2 focuses on function block diagram (FBD), continuous function chart (CFC) and structured text (ST).
