This practical book gives a comprehensive introduction to the concepts and languages of the new standard IEC 61131 used to program industrial control systems. A summary of the special requirements in programming industrial automation systems and the corresponding features in the IEC 61131-3 standard makes it suitable for students as well as PLC experts. The material is presented in an easy-to-understand form using numerous examples, illustrations and summary tables. There is also a purchaser's guide and a CD-ROM containing two reduced but functional versions of programming systems. These increase the value of the book for PLC programmers and for those.
