Eventually portal removes it from the plc, but oddly, it can continue running even when it is not in your project. Just pay attention and choose the proper option. |

Not possible for 1500 PLC. You have to delete the offline block first to be able to delete the online block. |

2022 S7-1515 and TIA V15.1 = I´m trying to do this. I select the "Delete" command and does not open any dialog, just the offline disappear and online remains grayed even doing this in online state and the status of PLC is not green anymore showing a warning about online-offline difference. The grayed block does not have delete option. How can I desapear definitively a DB block that is not necesary any more? |

When you delete a DB, then you need to download the software, to get the deleted DB off from the PLC. But when it's about DB's, TIA will ask for DB initializations of DB's when you do that, and if you proceed, all DB's will be set to start values. |
