Understanding CompactLogix

In this chapter, we will introduce the CompactLogix platform by exploring its genesis and evolution since its initial launch in 2001. We will explore the myriad different versions and form factors that are available within the CompactLogix product line and their typical use cases. The CompactLogix product line is by far the most confusing of the Rockwell Automation family due to the wide range of low-cost products and confusing naming conventions. I will attempt to unravel this product line throughout this chapter.

This chapter will cover the following topics:

• Introducing CompactLogix controllers
• Navigating the CompactLogix controller family
• CompactLogix deprecated controllers
• CompactLogix 5370 controllers
• CompactLogix 5380 controllers
• CompactLogix 5480 controllers
• Identifying compatible products

In the first section of this chapter, we will introduce the CompactLogix family of controllers and provide an overview of its history.
