Alarm Expression is used for states that are not reported through the process object alarms. It is a useful tool to get information in an Alarm and Event list based on property values. You can define an expression related to a property value, which gives you a redefined message line in the list.
How to understand alarm expression and how to configure alarm expression, please refer manual System 800xA 5.1 Configuration page 138 to page 150. there are some examples for your reference.
