For the CPU 315-2:

The transfer of the blocks to the MMC, is that performed automatically when downloading blocks or not? That is the question.

My support colleagues advise me to to a full Download User Program to Memory Card. From what I read on the net i get the impression it is not necessary.

Thankful for input.

Hi,

it´s not necessary to download the programm to mmc. After downloading the programm in the cpu all data is saved on the MMC. But you can choose "copy ram to rom" so that current values in DB will be saved on MMC too.

When you have some older CPU´s without MMC you always should choose "copy ram to rom".
