A total of 2048 bytes of data can be retentive in S7-1200 CPU. Not more than that |

Hello bathio, What does your application demands? How many bytes you need to retain? Check this if it helps you. In STEP 7 V11 how do you configure data blocks with the "Only store in load memory" attribute for the S7-1200? |

You need to archive data and view it later for some analysis, is it your exact requirement? |
