Product Description

CODESYS and IEC 61131-3 are leading the charge towards platform independence in the automation industry (similar to the same advance in the PC and Smartphone industries of the 1980s and 2000s). The Book of CODESYS is a key resource to gain an early lead in this market shift.

The Book of CODESYS makes extensive use of detailed graphics to help new users transition to CODESYS while also providing substantial detail, tips, and best practices for experienced users wishing to take their expertise to the next level. It includes numerous structured and unstructured hands-on labs to solidify the knowledge gained in each chapter. The Book of CODESY points out the best aspects of each IEC 61131-3 language and where each is best applied, covers traditional PLC programming as well as next generational techniques, and is applicable to all automation industry segments (including Factory, Mobile, Energy, Embedded, Process, and Building).

With over 7000 hours in the making, The Book of CODESYS is the most comprehensive CODESYS and IEC 61131-3 training and reference resource available. In book form, it is much easier to skip over areas already mastered, reread areas for better understanding, and skim for specific pieces of information. The Book of CODESYS is ready to help you in every stage of your mission to master CODESYS and IEC 61131-3.

About the Author

Gary Pratt is a licensed Professional Engineer and president of ControlSphere Engineering. He began his career in 1982 designing instrumentation and control systems for Chevron Corporate Engineering in San Francisco. Gary ventured into PCB/FPGA design for medical imaging systems and marketing for integrated circuit design tools before returning to his roots in instrumentation and controls on the first PLC system to control a GE gas turbine engine.

From there Gary discovered CODESYS and its significant superiority over other development systems and became an instant evangelist – first for an innovative manufacturer of an extreme cyber secure CODESYS-based PLC, and eventually serving as founding president for CODESYS North America. These days Gary dedicates his time to passing his knowledge on to the next generation and helping CODESYS users get started in the right direction. The monumental effort in the publication of this book is a major milestone in this mission.
