### **Cons of the Modicon AM-M907-122**
1. **Age of the Product Line**
The M900 series is not a brand-new product line; it has been around for over a decade. While this does not necessarily mean it is outdated, newer PLCs from Schneider Electric (e.g., the Modicon M580 or EcoStruxure Micro PLCs) may offer additional features like built-in HMI, more advanced communication options, or improved software tools. This could make the AM-M907-122 less future-proof in terms of software and hardware upgrades.
2. **Software Limitations**
The programming environment for the M900 series, EcoStruxure Machine Expert, is robust but may lack some of the advanced features found in newer Schneider Electric software platforms. For example, newer PLCs often include built-in support for IoT, machine learning, or more intuitive drag-and-drop programming interfaces.
3. **Cost of Replacement Parts**
While the PLC itself may be affordable, replacement I/O modules or other components could become costly over time, especially if they are no longer in active production. Users should ensure that critical modules are readily available or have backup inventory.
4. **Learning Curve for Newer Users**
The M900 series uses a more traditional PLC programming paradigm, which may require additional training for engineers or technicians unfamiliar with older PLC architectures. Newer PLCs often simplify programming with more user-friendly interfaces.
5. **Limited Built-in Safety Features**
Compared to newer Schneider Electric PLCs, the AM-M907-122 may lack integrated safety features like built-in safety relays or advanced safety protocols (e.g., T V-certified safety functions). Safety applications may require additional hardware or software modules, increasing complexity and cost.
