Allen-Bradley PLCs all feature modular construction and many options for customizing the hardware to my needs. Integral communication protocol options include a DFI Serial interface and Ethernet/IP. These protocols are used to communicate to other PLC processors, remote I/O racks, and networked devices, such as Drives and Motion Controllers.
All Logix family controllers use a common instruction set, which makes it easy to learn to program on one controller and extend that knowledge to other controllers.
There are three main families of Allen-Bradley PLCs:
MicroLogix, CompactLogix, and ControlLogix.
In this course, we will use a MicroLogix 1100 processor, which is a great PLC model to learn basic ladder programming for Allen-Bradley PLC’s.
