Hello, no you don´t need more (ok, you need wiring cables, but that is obvious). The CPU is connected via backplane to the DI/DO, and the connector for this is sent with CPU and DI/DO. Maybe this manual is also helpful for you SIMATIC S7-300 CPU 31xC and CPU 31x: Installation Best regards Bilao |

I think you also need a suitable 24 VDC power supply; Siemens has nice trusted power supplies which can be fitted at the same rail beside the CPU. |
