Hello, Perhaps the following FAQS might help: 1-How can I get an overview of the S7-400 memory concept? The load memory can be divided into the external and the internal load memories. The internal load memory is a RAM memory which is integrated into the CPU. Blocks can be transferred from the programming device (PG) to the load memory in the CPU with "PLC/Load". The main memory is updated here at the same time, whereby the runtime-relevant code and data blocks are transferred to the main memory. 2-How can you write the program to the FLASH Memory Card when using a SIMATIC S7-400 CPU? 3-How can you load projects to a memory card and back again to a PG/PC? "Download User Program to Memory Card" function downloads a user program to the memory card of a CPU. "PLC > Save to Memory Card..." or "PLC > Retrieve from Memory Card...". Now the complete project data is written to the memory card or retrieved from it. |
