Applied Automation I present a clear and concrete of the basic concepts of automation based on PLCs, addressing only sequential applications. We wanted to do it in the most complete - or less superficial - possible. We try to take care leave, whenever possible, the starting point in each issue presented, without the need for pre-requisites for your understanding; and consequent implementation.

We devote the first chapter to the description of automated systems through standard IEC 60848, presenting the SFC (Sequential Function Chart - Functional Diagram Sequential), which is a powerful tool of communication among the various areas that are usually involved in the development and use of automated systems (Control, Electrical, Electronic, Hydraulic, Computer, Mechanical, Pneumatic, etc). Moreover, it is an indispensable resource for consistent implementation of solutions.
In the second chapter we made a brief introduction to the PLC (Programmable Logic Controller - Programmable Logic Controller). The subjects of this chapter have been treated in detail in the following chapters, presenting gradually the hardware of the PLC. In Chapter three presents the basic architecture of the PLC, describing each block with its characteristics and functions performed, and the fourth chapter presents some care to be taken during setup / specification of a PLC. We in general, in chapter 5, the programming languages and tools for PLCs. And in chapter six the present system of operation of a PLC, highlighting the particular form as the CPU handles and manages the information.
In chapter seven started the presentation of the programming of PLCs through the fundamentals of programming, which highlighted the basics needed for implementation of programmes implementing consistent. In the following chapters demonstrate, it also gradually and with examples of application, the basic instructions of Language Ladder: Boolean instructions of entry, exit and immediate (chapter eight), Boolean instructions for comparison (chapter nine), timers (Chapter ten), accountants (Chapter eleven) and Recorder displacement (Chapter twelve). Finalizamos this part two methods with advanced programming language in Ladder: program by stages (Chapter thirteen) and seqüenciadores (Chapter fourteen).
The last chapter dedicated to software programming DirectSOFT, which is a programming tool in the Windows environment for PLCs Automationdirect.com (used as a reference in other chapters) with valuable resources, publishing, documentation, monitoring and debugging.
We hope with this work Tuesday provided a contribution to training and technological upgrade of students and professionals Brazilians.
