Note
Updating existing blocks
If an older version of the blocks of the PCS 7 SIRIUS motor starter library was previously
used in the project, this can then be updated. When the motor starter blocks are inserted, a
dialog is displayed for updating the blocks. It must be confirmed with "Yes".
When the SIRIUS MS PCS7 Block Library is installed, a prompt appears for deleting the
previous version.
Following the update of the CFC generation and the download, the CPU must be restarted.
