3.CREATING THE HARDWARE CONFIGURATION FOR THE CPU 314C-2DP
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.
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).
CPU:
Here, the S7 program and the networked connection partners (Connections/CO*1) are entered.
SIMATIC 300 stations: Here, the corresponding hardware configuration data (Hardware/SC*1) and CPU data are stored.
Sources/SO*1:
Here, sources (e.g. SCL sources) are stored which can be changed into executable programs through conversion.
Blocks/APoff*1:
Here, the program blocks ( OB, FB, FC, SFB, SFC, DB etc. ) are stored.
Symbols/SY*1:
Here, the symbol lists for symbolic addressing are stored.
S7 Program:
Here, the user programs (Blocks/AP off*1), symbol tables (Symbols/SY*1) and sources (Sources/SO*1) are managed.
