The memory of a Siemens S7-1500 PLC is divided into different areas:
|
||
|
|
|
||
|
|
1. **Load Memory (LM)**: This is where the user program and the system data are stored permanently.
|
||
|
|
2. **Work Memory (WM)**: This is used for temporary data storage and is divided into:
|
||
|
|
- **Program Memory**: For storing the executable version of the user program.
|
||
|
|
- **System Memory**: For storing system data temporarily.
|
||
|
|
- **Data Memory**: For storing data blocks, data areas, and instance data.
|
||
|
|
3. **Retentive Memory**: This memory area retains its data even after a power failure, and is used for data that needs to be preserved.
