S7-300 Programmable
Controller
Quick Start
Primer
The Primer offers a basic introduction to the methodology of the structure and
programming of an S7-300/S7-400. 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.

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.

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).
