摘要: A method (500) includes obtaining (501) history trend data of a process variable. The also determining (503) one or more change points (204) in mean value (202, 206, 208) the variable for predetermined time interval using point analysis. further detecting (505) significant that occur during interval. In addition, includes, each detected point, providing (509) notification to user receiving (511) information from about cause and generating (513) an event log (120). is based on received point.
