With LOGO! a wide range of control tasks can be implemented easily and flexibly - from applications in building and installation technology to tasks in control cabinet construction and in mechanical and instrument engineering. Distributed local control of machines and processes is possible by connecting up a communication module such as AS-Interface. Many switching devices can be replaced with the eight basic and 28 special functions in the logic module for Micro Automation. This practical book describes in a lively manner how programs are developed and hardware is chosen. It explains the standard situations of control technology on the basis of a guide, but also with many practical project tasks. From the quick start to program simulations, the reader is given comprehensive training on the different basic variants and expansion modules, allowing very flexible and precise adjustment to special tasks. The book includes a CD containing a demo version of LOGO!Soft Comfort, the examples described in the book, and the LOGO! manual in different languages.
