C.T. Jones received his Bachelor of Science in Electrical Engineering from Howard University, and has made his career in the Industrial Automation Industry for over 25 years. During this time he has served both as an automation user, and in automation vendor roles that include product marketing, applications engineering, and technical instructor. It was in the role of Control Systems Engineer for Procter and Gamble that a fascination with PLCs and their endless possibilities in automation drew him into the field that he has passionately pursued ever since. Early on Mr. Jones became aware of the difficult position of end-users with the tough balancing-act of keeping the plant operational and staying abreast of automation technologies. To meet the need, he authored the very first book on PLC technology - Programmable Logic Controllers Concepts and Applications. This first book was soon followed by, Programmable Logic Controllers - The Complete Guide to the Technology, designed specifically to give students and practicing engineers a ready guide to sound principles and practices for implementing all aspects of PLC technology. While serving as Applications Engineer and Technical Instructor for Siemens Energy and Automation, Mr. Jones devoted much of his time to developing step-by-step application notes and other educational materials for Simatic users. This step-by-step approach is reflected in Mr. Jones' book STEP 7 in 7 Steps - A Practical Guide to Implementing S7-300 and S7-400 Programmable Logic Controllers.
