---

### **Cons of buying a 6ES5465-7LA11**

1. **Limited I/O Capacity**

- The **CPU 315-2DP** has only **2 digital inputs and 2 digital outputs**, requiring additional expansion modules for larger applications.

- Analog inputs are limited to **2 channels**, which may be insufficient for complex process control requiring more sensors.

2. **Outdated Technology Compared to Modern PLCs**

- **No built-in Ethernet port** (requires an optional **CP342-1** or **CP343-1** communication processor for Ethernet/IP).

- **Slower processing speed** compared to newer **S7-1200/1500** or **S7-1500T** controllers, which offer faster scan times and more advanced features.

- **Lacks integrated safety functions** (e.g., STO, SBC) found in modern safety-rated PLCs.

3. **Programming Complexity**

- **Ladder Logic (LAD) and Function Block Diagram (FBD)** are the primary programming languages, which may be less intuitive than **Structured Text (ST)** or **Graphical Programming** in newer controllers.

- **TIA Portal** is more feature-rich than older **STEP 7** versions, requiring some learning curve for users transitioning from legacy software.
