Alarm texts must be configured in the operator interface.
Note
If an alarm is to be output in the language active at the user interface, then the user requires
information about the language that is currently set at the HMI. This information can be
interrogated in the part program and in the synchronized actions using system variable
$AN_LANGUAGE_ON_HMI (see "Currently set language in the HMI [Page 899]").
