random access memory

"Programs stored in RAM are lost when you reset the CPU memory (MRES) or if you remove the CPU or RAM memory card.

Programs saved on EPROM memory cards are not erased by a CPU memory reset and are retained even without battery backup (transport, backup copies)."

CPU Load Memory

The load memory is used to store the user program without the symbol table and the comments (these remain in the memory of the programming device).

Blocks that are not marked as required for startup will be stored only in the load memory.

The load memory can either be RAM, ROM, or EPROM memory, depending on the programmable controller.

The load memory can also have an integrated EEPROM part as well as an integrated RAM part (for example, CPU 312 IFM and CPU 314 IFM).

In S7-400, it is imperative that you use a memory card (RAM or EEPROM) to extend the load memory.

CPU Work Memory

The work memory (integrated RAM) is used to store the parts of the user program required for program processing.
