Hello srjth09; Please explain a little more carefully what you would like to do. On your CPU, all data from the programming PC is loaded into the MMC, which is a Flash memory card. This acts as a retentive Load Memory, which holds all your system and program blocks without battery support. When you launch or start the CPU, the necessary blocks are automatically transferred to the CPU's RAM memory (known as the Work memory), and additional blocks are added or removed from RAM as required by the operation cycle of your program. Please look at the following FAQ: How can you obtain an overview of the memory concept of SIMATIC S7-300 CPUs and C7 devices? https://support.industry.siemens.com/cs/ww/en/view/7302326 The case of your particular CPU is examined in Point 4 of the document: CPUs with MMC bay. Hope this helps, Daniel Chartier |
