Links to each article below.

1. Ladder logic’s future role in automation

Nine considerations when selecting a programming language. Ladder logic is favored by manufacturers in discrete industries, but as technology and automation evolve, its usefulness compared to other IEC 61131-3 programming languages and PC programming depends on application complexity and other factors. 

2. How to manage IoT implementations

Evaluating the current state of the organization is key to understanding where and how to start implementing an Internet of Things (IoT) solution.

3. Case study: IIoT effectiveness on the plant floor

Create and collect machine and sensor data to augment overall equipment effectiveness (OEE) and determine machine efficiency.

4. Fog computing standard established

The OpenFog Consortium’s OpenFog Reference Architecture for fog computing has been adopted as an official standard by the IEEE Standards Association (IEEE-SA) as a universal technical framework that enables the data-intensive requirements of the Internet of Things (IoT), 5G, and AI applications.

5. Comparing ladder logic and object-oriented programming

Cover story: Many young automation professionals are comfortable with object-oriented programming (OOP), but ladder logic remains the standard for industrial automation applications. See advantages and disadvantages of OOP and ladder logic.
