 In this book, I aim to explain the basics of automation with Simatic as if I were speaking to a friend or acquaintance. I use straightforward language to describe or paraphrase complex topics, like the REAL type, when needed. Automation can be pretty complicated, but I will try to help the reader navigate the many technical details with a simple, practical approach. In this book, I aim to explain the basics of automation with Simatic as if I were speaking to a friend or acquaintance.

 +**SIMATIC** is a series of programmable logic controllers and automation systems created by Siemens. First launched in 1958, the series has evolved through four major generations, with the most recent being the SIMATIC S7 series. It is designed for industrial automation and manufacturing processes.
  
 +The name SIMATIC is a registered trademark of Siemens. It combines the words //"Siemens"// and //"Automatic."//
 +
 +In 1959, the Simatic G was introduced, a system designed to replace relay logic with a hard-wired programmable logic controller that used Germanium transistors. It was marketed as the //"Building-Block System for Solid-State Controls."// 
 +
 +In 1964, the Simatic N was launched, featuring a hard-wired programmable logic controller based on Silicon transistors. 1973 saw the release of the Simatic S3, the first system with a microprocessor that enabled programmable logic. 
 +
 +In 1979, the Simatic S5 series was introduced and remained in use until 2000, with systems still operational worldwide. Programming was done using STEP 5 software. The S5 U (universal) controllers were introduced in 1984. 
 +
 +In 1994, the Simatic S7 series was launched, mainly consisting of the S7-200 for simple automation, S7-300 for general use, and S7-400 for large-scale projects, all supporting networking via Profibus or Industrial Ethernet.
