8.2 Commissioning procedure
S7-300, CPU 31xC and CPU 31x: Installation
8-2 Operating Instructions, Edition 08/2004, A5E00105492-05
Recommended procedure: Hardware
With its modular structure and many different expansion options, the S7-300 can be very
large and extremely complex. It is therefore inappropriate to initially start up an S7-300 with
multiple racks and all inserted (installed) modules. Rather, we recommend a step-by-step
commissioning procedure.
We recommend the following initial commissioning procedure for an S7-300:
