Hi all, I'm getting closer to the commissioning day and I have an additional doubt. Let's say I remove the original MMC and install the new one for my tests (with different I/O settings etc). Once i put back the old MMC should I find the DB retained values (i.e. like when I switch off and on a plc after a power cut) or will I find the DB start values? I'm expecting the retained values, since everything should be saved at the MMC, but I'm just searching for an expert confirmation or a link where I can get these things well explained. Thank you! ------------------------------------------------------------------------------------------ |

Hello wally; There are ways to ensure that your DB actual values are saved as initial values, so when you open the DB in runtìme the old actual values will be available as initial values . But this operation must be done manually. See the links in this Step 7 (v5.5) FAQ: https://support.industry.siemens.com/cs/us/en/view/109478260 Hope this helps, |
