Hello kachkachuri; Thank you for the information on ypur system. In order to share the same terms in our explanation, you should start by reading this article, describing the S7-300 CPU memory concept: https://support.industry.siemens.com/cs/us/en/view/7302326 Your CPU corresponds to case #4 in the document, SIMATIC S7-300 CPUs and C7 Devices With MMC Bay. In your case the 24 kB referred to in your CPU description corresponds to Work Memory. But you have no Load memory, which is on the MMC that you need to insert in the memory card slot on the CPU. So you cannot dowload any block to your CPU until an MMC is provided and inserted in the PLC. The smallest size of Simatic MMC you can purchase is 64 kB,
The different MMC for your CPU are shown in this FAQ: https://support.industry.siemens.com/cs/us/en/view/9274152 The 64 kB MMC is quite sufficient for the needs of your CPU. Please do not use a MMC from a non-Siemens provider, and never try to format a Simatic MMC using your Windows OS, you would make it unreadable from a Siemens CPU. Hope this helps, Daniel Chartier
