6.6.3 Configuration
Introduction
You configure the integrated I/O of CPU 31xC with STEP 7. Always make these settings
when the CPU is in STOP. The generated parameters are downloaded from the PG to the
S7-300 and written to CPU memory .
You can also choose to change the parameters at SFC 55 in the user program (see the
Reference Manual
System and Standard Functions ). Refer to the structure of record 1 for
the respective parameters.
