Chapter 2. Industrial Network Communications
In this chapter, we will discuss the various communication technologies available for the Logix platform. The focus of this book is the current state of Rockwell Automation's ControlLogix and CompactLogix controllers; however, we will touch on some legacy communication protocols, which you may still find running in the field today. Communications allows us to interface with controllers, racks, and devices on our network. Establishing communications is an important step that enables us to connect with a device and transfer configuration changes and programs. After completing this chapter, you will be familiar with all the Rockwell Automation communication technologies that are actively used in the field today. This chapter will cover the following key areas of industrial network communications in the Logix platform:
Key terms in industrial communications
Primary network technologies used today
Legacy network technologies you may encounter in the field...
