Totally Integrated Automation is the concept by means of which SIMATIC controls machines, manufacturing systems and technical processes. Taking the example of the SIMATIC S7 programmable controller, this book provides a comprehensive introduction to the architecture and operation of a state-of-the-art automation system. It also gives an insight into configuration and parameter setting for the controller and the distributed I/O. Communication via network connections is explained, along with a description of the available scope for operator control and monitoring of a plant. The new engineering framework "TIA Portal" combines all the automation software tools in a single development environment. In the TIA Portal, SIMATIC STEP 7 Professional V11 is the comprehensive engineering package for SIMATIC controllers. As the central engineering tool, STEP 7 manages all the necessary tasks, supports programming in the IEC languages LAD, FBD, STL, S7-SCL and S7-GRAPH, and also contains S7-PLCSIM for offline tests. As well as updating the previously-depicted components, the fifth addition also presents new SIMATIC S7-1200 hardware components for Profibus and Profinet. In addition to the STEP 7 V5.5 engineering software, now STEP 7 Professional V11 is also described, complete with its applications inside TIA Portal. The book is ideally suited to all those, who, despite little previous knowledge, wish to familiarize themselves with the topic of programmable logic controllers.
