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.
