Hello automation_1; A rule of thumb that is always practical: load memory should be 1.5 times (approximately) the size of work momory for a S7-300. Larger if you want to hold a big program or you want to insert external files (such as the archived program for later retrieval, for example. Your work memory is 96 kb; the 1.5 rule would require a 144 kB MMC, which does not exist. So either you choose a 128 kB MMC and take your chances, or you go to the nearest larger model, at 512 kB.
