For courses in Programmable Logic Controllers where the Allen/Bradley programmable logic controller is the controller of choice. 

This text emphasizes the Allen Braldley SLC 500 PLC and covers all three Allen Bradley PLC's (PLC 5, SLC 500 and Control Logix). As a result, it is the most comprehensive PLC text available.  The primary focus of the text is "ladder logic programming", but chapters on switches, sensors, output actuators, process control, industrial networks and three other PLC languages (function block diagrams, structure text, and sequential function charts) are also included.
