In many cases, meter trend data is already recorded in the trend repository of the building automation system. However, it is less common to record other equipment's trend data in the trend repository, so the user has to configure this manually. You must store equipment trend data in the ADX server of the building automation system in order for the data collector to gain access to the data. OBEM can access data points whose trend repository is enabled and whose data is stored in the ADX server.
