ControlLogix consists of a common control engine with a common development environment and tight integration between the programming software, controller, and I/O modules. This close integration greatly reduces the automation engineering development time and cost.
Even though the ControlLogix platform is over 20 years old, it is still in the early stages of its product life cycle. For example, Allen-Bradley's 1747 series SLC-500 family, which was introduced in 1989, is still under support today. Although it is no longer actively developed, the SLC-500 represents a product life in excess of 25 years.
The following is a diagram that details the look of a typical ControlLogix L5 processor card:
We will next discuss the following ControlLogix controllers in the upcoming subtopics:
- ControlLogix Series 6 controllers (L6)
- ControlLogix Series 7 controllers (L7) ...
