Updated to reflect recent industry developments, this edition features practical information on Rockwell Automation's 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.

Benefits:

• Coverage examines how Rockwell Automation's 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.
• The hands-on Lab Manual, now subtitled "Programming the SLC 500 PLC using RSLogix 500 Software," has been updated to include more information on RSLinx drivers for the MicroLogix as well as a new Ethernet driver configuration lab for the SLC modular processor, the 5/05.
• 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.
