Could anyone confirm that the 317-2 DP use MMC as retentive memory for DB?

Hello Corben;
If the data is retained in the MMC (newer S7-300 CPUs) there is no limit to the time of retention. .......
Hope this helps,

HiChartier,

Do you mean the retentivity of S7-300 CPUs with version start from V2.0 is realize by the MMC? DB, Timer, Counter are concerned?
