Updated to reflect recent industry developments, this edition features practical information on Rockwell Automations SLC 500 family of PLCs and includes a no-nonsense introduction to RSLogix software and the new ControlLogix PLC. To assist readers in understanding key concepts, the art program has been modernized to include improved illustrations, current manufacturer-specific photos, and actual RSLogix software screens to visibly illustrate essential principles of PLC operation. New material has been added on ControlNet and DeviceNet, and a new chapter on program flow instructions includes updated references to the SLC 500, MicroLogix, and the PLC 5. Salient Features Coverage examines how Rockwell Automations SLC 500 and MicroLogix PLCs work and program, leading to a better understanding of fundamental processes A clear-cut orientation to general principles underlying all PLC operations enhances readers ability to assimilate more advanced concepts and instruction sets in later chapters New exercises in the Lab Manual complement the new program flow instructions and take readers through jump to subroutine, jump to label, MCR, and the immediate input instruction Table of Contents 1.
