{% endcolumn %} {% column width="8.333333333333343%" %} {% endcolumn %} {% endcolumns %} *** ### Description With this library you can read, filter and use alarms from the CODESYS AlarmManager via IEC code for further functions – e.g. for e-mail notifications, custom logic or visualizations. The library provides an alarm buffer, traversal mechanisms and a flexible rule set. Based on alarm classes, alarm groups and other criteria, policies and groups can be defined that determine when and how alarm messages are processed or sent. The main components are: * Access to all alarms of the AlarmManager via IEC code * Buffering of alarms in a high-performance alarm buffer * Filtering of alarms by type (e.g. alarm class, alarm group) and text * Management of policies (rules) and groups to define alarm behavior * E-mail notification for relevant alarm conditions * Status and diagnostic information for e-mail delivery * Utility blocks such as timers and FIFO buffer *** ### Details *** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
