Links to each article below.

1. Tips on sensor selection

Many different sensors are available to manufacturers and knowledge about the application type and basic operation conditioning requirements can create a more informed and accurate choice.

2. Five reasons to use modular design enclosures

Modular design enclosures provide more flexibility and a reduced footprint for users versus unibody enclosures, and their design and construction provide additional advantages for users. 

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. 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. 

5. Comparing conventional and sustainable safety instrumented systems

A sustainable safety instrumented system (SIS) is more open than a conventional SIS and are more accessible to process plant personnel while providing opportunities for continuous feedback and improvement. 

The list was developed using CFE Media’s web analytics for stories viewed on controleng.com, Jul. 9-15, for articles published within the last two months.
