Automating with STEP7 in LAD and FDB: SIMATIC S7-300/400 Programmable Controllers (With Diskette)

SIMATIC S7 programmable controllers are used to implement control systems for machines, manufacturing plants and indsutrial processes. The relevant open-loop and closed-loop control tasks can be solved using the STEP 7 programming software, which has been developed on the basis of STEP 5, with its various programming languages. This book describes elements and applications of the graphic-oriented programming languages LAD (ladder diagram) and FBD (function block diagram) for use with both SIMATIC S7-300 and SIMATIC S7-400. It is aimed at all users of SIMATIC S7 prgrammable controllers. First-time users will be introduced to the field of programmable logic control whereas advanced users will learn about specific applications of SIMATIC S7 programmable controllers. The enclosed diskette contains many programming examples written in LAD and FBD and archived within block libraries. The examples can be viewed, modified and tested using STEP 7.
