You can use the HDA Items category to view the status of the traces on Historic Trends. This is useful if your Historic Trends are showing different data than expected, as you can use the status information to determine whether the Historic Trend has the correct configuration.
If the trace that you expect to be shown on the Historic Trend does not have an entry on the HDA Items category, the Historic Trend does not recognize the trace. This is an indication that the trace cannot be displayed possibly due to the Historic Trend having incorrect configuration.
If the trace that you expect to be shown on the Historic Trend has an entry in the HDA Items category, the Historic Trend recognizes the trace but is not displaying it, so there may be a software fault. Please contact Schneider Electric for assistance.
