"Automating with S7...STL/SCL" is a reference book for any EXPERT programmer using Siemens S7 PLCs. Hans Berger, the author, is the "father" of S7 PLC family (in a technical way). If you want to reach the EXPERT level, YOU MUST HAVE THIS BOOK!!!...." (ValRo, USA; Amazon, 06/2008) "This book cover the most important tools, that Simatic Manager offers. The autor first starts with the basic concepts about the programmable controller like the process image, for update the inputs and outputs, and automation networks. The book covers the most important information about Stament List languaje that is more efficient that the ladder lenguaje and it can be very important for systems that have critical time tasks. The autor explains how the interruptions are configured and how each function is called inside the organization blocks. For people that work with PC of SIEMENS is the book that they need for consult some fundations, Actually i am developing a Tesis about Monitoring and Diagnosis Automation Systems with the Simatic Controllers at this book is my reference about the controllers (the autor explain the service of communication, one concept that many engineers dont know that exist). I am waiting the next book of the S7-1200 of Hans but in english please, i dont know german."(Amazon, Mai 2010)
