The section of the configuration forms the main part of the configuration. Each "tab" has different functionality and shows a different aspect of the data. Tab 1 shows multiple hour threshold crossing aggregates (i.e. highest crossing over 4 hours). Tab 2 shows highest alarms on an hourly basis. Tab3 gives a text summary of alarms and the optional tab 4 can be used to show additonal site data.
