HaiMarcjan, 1. if am having RAM card (s7 400), while downloading it will go to cpu internal memory.once it become full, program will get download in to RAM card. CORRECT ?? 2. if am having flash card , while downloading it will go to cpu internal memory only. To transfer in to FLASH card,save to memory card should use. so my doubt is, a. am having 400 system with flash card b. am trying to download with out inserting FLASH card, then i will get errror that no enough memory. all blocks will not get downloaded. c. am trying the same ( normal download, notsave to memory card) after inserting FLASH card, then its getting downloaded properly . then what does it mean ? why its happening like this ??\ any comment will be very helpful. i couldnt solve my doubt with MEMORY CONCEPT FAQ. regards vipz |

Hi justino, The function copy RAM to ROM is not supported in S7-400. read at the bottom: What is the effect of the STEP 7 function "Copy RAM to ROM"? |
