Messages in the Event Historian display can further be filtered by Message Class and Message Type. The
main display area of the Event Historian Filter window is divided into two portions; the left side is labelled
Message Class, and contains buttons which display the available Message Class names. The right side of
the main display area contains a list box, which in turn contains a scrollable list of all the Message Types
available for the selected Message Class.
When a new Message Class is selected, the list of Message Types in the list box changes to display the
types available for that Message Class. Each Message Type has a pushbutton associated with it; click this
pushbutton to select or deselect the Message Type. If a Message Type is selected, the messages of that
type will be filtered out, and will not be displayed.
