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.

Parameters of standard DI

The table below gives you an overview of the parameters for standard digital inputs.
