The blocks in your circuit program require a certain amount of memory space. The table shows you how much of the memory space each block occupies.
The "Rem" column (retentivity enabled) specifies the memory space required for data backup after power failure.

*: Depending on whether the function is configured with or without retentivity, it occupies the following memory space:
Retentivity off: The function occupies RAM space
Retentivity on: The function occupies REM space
Here you will find information on memory space provide by LOGO!.
