In Step 7, files are managed with the 'SIMATIC Manager'. Here, program blocks can be copied, for 
example, or called for further processing with other tools by clicking on them with the mouse. Use of 
the SIMATIC Manager is in line with the usual Windows standards (e.g. right-clicking on a 
component causes its selection menu to appear). 
 
In STEP 7, each project is created with a fixed specified structure. The programs are stored in the 
following directories: 
 
 
 
 
 
 
 
 
 
 
 

 

 
 
 
 
 
 
 

 

 

Project: 
This directory contains the 
hardware (e.g. SIMATIC 300 
stations) and the subnets 
(e.g. MPI and PROFIBUS). 

SIMATIC 300 stations: 
Here, the corresponding 
hardware configuration 
data (Hardware/SC*

) and 

CPU data are stored. 

Here, sources (e.g. SCL 
sources) are stored which 
can be changed into 
executable programs through 
conversion. 

Here, the program blocks 
( OB, FB, FC, SFB, SFC, 
DB etc. ) are stored. 

Here, the symbol lists for 
symbolic addressing are 
stored. 

CPU: 
Here, the S7 
program and the 
networked 
connection partners 
(Connections/CO*

) 

are entered. 

S7 Program: 
Here, the user programs 
(Blocks/AP off*

), symbol 

tables (Symbols/SY*

) and 

sources (Sources/SO*

) are 

managed.
