Hello eu1958; And welcome to the Siemens A&D forum. For starters, note thatmost manuals and FAQs from Siemens can be downloaded in various languages, including Spanish, if this can help. Just follow the links and locate the language you need in the top or the bottom of the destination webpage. Now for your question: the MMC that you insert in a S7 Compact CPU is used as Load Memory for that CPU; as such you must have one inserted in the CPU for it to recieve the program blocks that it will run in Work Memory.To understand better the memory concet of these CPUs, have a look at the following documents and the attached screencapture from the techniocal specifications manual: How can you obtain an overview of the memory concept of SIMATIC S7-300 CPUs and C7 devices? SIMATIC S7-300 CPU 31xC and CPU 31x: Technical specifications Now, if you have a large enough MMC you can also add external files on it, such as projects, drawings... How can you also store other files that belong to the project or plant on the MC/MMC? Is the memory card you insert in your S7-313C a new card, or is it from an older project/CPU? If that is the case you must reset it before using it again. How do you reset a SIMATIC S7-300 CPU and MMC (default reset or overall reset)? How do you delete the data on an MMC (micro memory card)?
