Hello Tozzi; Your CPU has work memory (in RAM) where your program will be executed, system memory where the processor data and parameters are held, and load memory, on your MMC., where your programming PC transfers the user program. If you have no MMC then you are missing a very important part of hhe processor's memory areas and you will have a major fault that can cause the CPU to go to Stop. See the screenshot below and the following link, describing the memory structure of your PLC (especially section 4 of the attached documentation): https://support.industry.siemens.com/cs/ww/en/view/7302326 Hope this helps, |
