When a memory card with user program is slotted into a CPU, the CPU copies the runtime-relevant program sections into the main memory.
- Slot the memory card.
- Do an overall reset.
- CPU copies the runtime-relevant sections of the program from the load memory into the main memory. In particular this initializes the data blocks in the main memory (their initial values are reset).
A PG is not required for this procedure. This applies, for example, also when different user programs are stored on different memory cards and are to run at different times in the same CPU.
- The memory card must remain slotted for as long as the CPU is in operation, especially in RUN.
- The CPU transfers the program from the load memory into the main memory even after "Power off" without buffering (also even if the battery has undervoltage during "Power off").
