The memory usage function is used to view :
- The physical distribution of the controller memory (see EcoStruxureâ„¢ 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 :
- 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 - 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
