The memory usage function is used to view :

• The physical distribution of the controller memory (see EcoStruxure™ Control
  Expert, Program Languages and Structure, Reference Manual) (internal memory and
  memory card)
• The space consumed in the memory by a project (data, program, configuration,
  system
• It can also be used to reorganize the memory where possible

Note : The memory usage screen is not available in simulation mode. This screen is only available in standard mode for a built application.
The screen is accessible if the application is built and is in the NOT BUILT state due to a program modification, but it corresponds to the previously built application. Modifications are taken into account at the next build

To access the memory usage details of the controller :

1. Activate the PLC > Memory Consumption... command to display the corresponding screen. The
   memory usage statistics of a project can only be accessed if you have generated its executable in
   advance
2. If you want to reorganize the memory to optimize it, activate the Pack command

Description of the parameters :

Memory re-organization :

Memory re-organization is activated using the Pack command. Memory re-organization can be performed in online or offline mode (even if the controller is in Run or in Stop).

Note : Certain blocks cannot be moved in online mode. You can attain a lower level of fragmentation by re-organizing the memory in offline mode
