Programmable logic controllers (PLCs) hardware advances have kept PLCs a strong choice for many automation applications, including machine control, motion control, even certain process control applications. Where are PLCs still a good controller choice and why? How have PLC designs changed to meet automation and control challenges? What criteria should be used for PLC selection.

Learning objectives
-Understand where (types of applications) PLCs can be effective.
-Review PLC features and learn best practices related to PLC hardware selection.
-See examples of how PLC hardware upgrades and selection helped applications and why.
