Alarm Expression
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 predefined message line in the list.
Figure 68. Config View for the Sequence Bar Aspect
When configuring a Sequence Bar aspect or an Alarm band aspect, the changes
will not be applied directly. The changes are applied after reloading the aspect or
restarting the workplace.
Before implementing alarm expressions, evaluate whether the OPC server in the
network has the performance to deliver data for the alarm requirements of the
system.
Update rate and data quality are the factors which affect Alarm Expressions.
