freire Posts: 3 Rating: (0)	Hi All I have a CPU with 98% Load Memory Ram used and only 32% Load Memory Eprom, I have trouble loading FC changes. Is it possible to change a few blocks from RAM to EPROM? Thanks. Attachment ram-eprom.jpg (87 Downloads)

Because during download FC/FB/DBgoes to RAM - designed for modification/testing.Download user program to memory card will ensure everything is on the EEPROM. http://support.automation.siemens.com/WW/view/en/23670532

The options offered by the S7-400 are given in Entry ID23670531. Please consider the CPU must be in STOP.
