A5E00261402-01 From S5 to S7, Converter Manual A5E00261402 01 Preface Purpose of the Manual This manual supports you when converting S5 programs into S7. With the information in this manual you can do the following: • Convert existing S5 programs into S7 programs and subsequently edit them manually if necessary. • Incorporate pre-converted S7 functions (previous S5 standard function blocks) into your S7 programs. Audience This manual is intended for programmers who wish to use existing S5 programs in S7. Where is this Manual Valid? This manual is valid for release 4.0 of the STEP 7 programming software. From S5 to S7, Converter Manual A5E00261402-01 iii Preface Where Does this Manual Fit in with the Rest of the S7 Documentation? There is a wide range of user documentation available to support you in configuring and programming an S7 programmable controller which is intended to be used selectively. The following explanations should make it easier for you to use the user documentation. This symbol indicates the order in which you should read the manuals, particularly if you are a first-time user of S7. Meaning Symbol This documentation introduces the methodology. This is a reference manual on a specific topic. The documentation is supported by online help.

It is especially suited to first-time users of an S7 programmable control system. S7-300 and S7-400 Program Design Programming Manual The S7-300/S7-400 Program Design Programming Manual provides basic information on the structure of the operating system and of a user program of an S7 CPU. The first-time user of an S7-300 or S7-400 should use this manual to acquire an overview of the programming methodology and to use it to base their user program design on. S7-300 and S7-400 System and Standard Functions Reference Manual The S7 CPUs have integrated system functions and organization blocks included with their operating system, which you can use when programming. The manual provides you with an overview of the system functions, organization blocks, and loadable standard functions available in S7, and – in the form of reference information – detailed interface descriptions for their use in your user program. STEP 7 User Manual The STEP 7 User Manual explains the main usage and the functions of the STEP 7 automation software. As a first-time user of STEP 7 and as an experienced user of STEP 5, this manual will provide you with an overview of the procedures used to configure, program, and start up an S7-300/S7-400. While you are working with the software you can access a range of online help topics which offer detailed support on using the software. Converter Manual From S5 to S7 You will need the From S5 to S7 Converter Manual if you want to convert existing S5 programs to run them on S7 CPUs. The manual provides an overview of the procedures and usage of the Converter; you can find a detailed description of the converter functions in the online help. You will also find the interface descriptions for the converted S7 functions available in the online help. Practical information is also provided on SIMATIC S7 hardware and software. Statement List, Ladder Logic, Function Block Diagram, SCL1 Manuals The manuals for the programming language packages Statement List, Ladder Logic, Function Block Diagram, and SCL (Sequential Control Language) contain both the user’s guide and the reference description of the programming language or representation type. You only require one language type for programming an S7-300/S7-400, but you can mix the languages within a project, if required. If you are using a language for the first time, it is recommended that you use the manual to learn about the methodology of creating a program in the chosen language first. While you are working with the software you can access a range of online help topics which offer detailed support on using the respective editors/compilers. GRAPH1 , HiGraph1, CFC1 Manuals The languages GRAPH, HiGraph, and CFC (Continuous Function Chart) offer additional methods of programming blocks in the form of sequential controls, state graphs, or charts. The manuals contain both the user’s guide and the reference description of the programming language. If you are using a language for the first time, it is recommended that you use the manual to learn about the methodology of creating a program in the chosen language first. While you are working with the software you can access a range of online help topics which offer detailed support on using the respective editors/compilers (with the exception of HiGraph). 1 Optional package for system software for S7-300/S7-400 From S5 to S7, Converter Manual A5E00261402-01 v Preface Structure of the Manual This manual assumes you have knowledge of S7 programs which you can read about in the Programming Manual /234/. You should also be familiar with using the Standard software, as described in the User Manual /231/.
