FAQ: SIMATIC S7-1500 CPUs and modules
Quick answers to help engineering, procurement, and maintenance teams align on the correct SKU set.
Select the CPU by required performance, interfaces, and your project’s platform standard. Once the CPU is fixed, size your DI/DO/AI/AO modules to the point count and add CM modules for any required communications.
DI/DO handle discrete on/off signals (e.g., sensors, relays). AI/AO handle continuous analog values (e.g., 4–20 mA, 0–10 V, temperature—module dependent).
Use a CM module when your application requires additional or specific communication capability beyond the CPU’s built-in interfaces—based on your network standard, protocol requirements, and system architecture.
