Figure 1-1 Interface modules for the FC 56
The configurations with the different interface modules are shown in appendix A.
The FC 56 can be used to all configurations.
S The interface module is operated directly on a SIMATIC S7-300.
S The interface module is located in the rack of an ET 200M or ET 200X. The
ET 200M/ET 200X is used on an S7-300 or S7-400.
S Since the interface module is a self-contained PROFIBUS slave, it is linked with
the integrated PROFIBUS connection to a SIMATIC S7-300 or S7-400.
These configurations can be mixed. Different interface modules can also be
connected.
Filehandler
The FC 56 uses the filehandler in ASM/SLG. This offers you the advantages listed
below.
S The user addresses his data by logical name (file name) consisting of
8 alphanumeric characters. The absolute address of the data is no longer
needed.
S Consecutive data are called files.
S The filehandler automatically manages the different file lengths.
S Files can be assigned access rights.
