In the new era of information technology developed, professional person has entered the industrial era of lifelong learning, and knowledge is accumulated, genius is hard work! In order that we can better learn industrial products, daily PLC training center in Suzhou (www.ttplc.cn) will soon launch Internet free and open courses, mainly for our students to provide a new way to learn, study and work for everyone encountered during PLC provide technical services on various issues. Applies to all learn to use various brands of PLC electrical control personnel, especially the old and new trainees PLC training every day!
