Sometimes an alarm must not be considered as an alarm. To close the alarm forcibly, click the  button (Close error forcibly). A list of the errors closed in this way can be seen by clicking the  button (Show closed errors). An additional table is shown on the right.

Left-clicking an entry in the alarm situation display area twice opens a dialog box, which explains the errors in the period of time described by the cell.

Left-clicking an entry in the reference information area twice opens a dialog box, which contains a full description of object properties.
