1. 2016 Engineering Choice Awards’ Finalists 

The Control Engineering Engineers’ Choice Awards highlight some of the best new control, instrumentation and automation products as chosen by Control Engineering’s print and online subscribers. 

2. PLC vs. PAC vs. IPCs

Know the features, limits, and compatibilities to select the right controller: programmable logic controller (PLC), programmable automation controller (PAC), or industrial PC (IPC).

3. Six steps to choose between PLC and DCS for process industries

Learn how to choose between PLC and DCS. Though PLC and DCS technologies were invented to serve different industrial processes, the last 15 years have seen a massive merger of functionalities between both worlds.

4. Fixing PID, Part 3

PID: Proportional-integral-derivative controllers may be ubiquitous, but they’re not perfect. Consider how deadtime affects integral action.

5. Critical decisions for selecting pressure transmitters

There are many considerations when it comes to selecting a pressure transmitter, and few are examined in school. Here’s advice to avoid tough lessons as you learn on the job.

6. How to select a controller

Applications and controller options vary widely. Take care in selection, especially in the overlapping areas. Functionality matters more than a name. Do you need a programmable logic controller (PLC), programmable automation controller (PAC), industrial personal computer (IPC), or distributed control system (DCS)? 

7. How to rank controllers

With the growing number of controller choices available to automation engineers, separating the chaff to find the best device for a particular application can be difficult.

8. Simulation: A game-like approach to innovation

The low price of oil has caused hydrocarbon companies to look at innovative ways of reducing their costs. Simulation modeling has recently emerged as a way of minimizing operating overhead or removing unnecessary scope from capital projects.

9. Top seven arc flash safety measures

Seven ways to limit the exposure of workers to the risk of arc flash incidents.
