When the ControlLogix controller was launched in 1997, it represented a significant technological step forward for industrial control systems. The ControlLogix platform is built on the ControlBus backplane, which performs like a mini-network and allows devices to be Removed or Inserted Under Power (RIUP). The L5 has since been discontinued (as has the L6) from the lineup, so we will focus on the newer L7 and L8 controllers in this book. Throughout this book, we will refer to the ControlLogix controllers as PACs, which is the modern-day equivalent of PLCs.
This chapter will cover the following topics:
- Introducing ControlLogix controllers
- Selecting a ControlLogix controller
- Introducing GuardLogix safety controllers ...
