Query: Total waste of time and money

Info: I read the 3rd edition what was published in 2004.General: The book is easy to read and does not keep repeating itself. The chapters are ordered in a way that seems logical.Bookcontent:70% of the book has nothing to do with SCADA but is informing you on ways of communicating, which can be used for SCADA. This part was written in a time that a 1200 baud modem was state of the art equipment AND THAT WAS NOT 2004! The rest of the book gives you a global idea what the difference is between RTU's and MTU's and what they can do. Based on the fact that the communication part is completely outdated this will be as well. It did not give me any additional information on what I already new.
