The PI-ML manual logger is a Windows-based client application that allows users to enter data manually into the PI real-time and historical plant information system. The PI-ML logs data that cannot be collected automatically from instrumentation and control systems. Users have three data-collecting options: They can use a hand-held terminal to record data in the plant, use a barcode reader to scan tag identifiers for data values or enter data directly into the data entry screen on a PC.
