Each trend will be specified with certain line in monochrome printers (for example  dot, line, straight etc) and with different color in color printers. Each operator or person who log in will be able to access fully customized trend pages. These pages  should be able to be customized by each user online by using drag and leave method or by using  standard configuration methods. All configurations which are present in certain configuration medium  will be able to be used by user for changing trend graphs while system is running. These will include  minimum pen color, pen scaling, grid, and trend tag assignments for each trend page. Historical Analysis  8.19.10 Historical Trend Data Analysis View  8.19.11 Reports 8_Vol3_d4.3_Section 8 electrical works_en_GIR.rev8.doc  Software will be able to display all reports with text types and colors which can be identified by user. Software will support printing operations in specified reporting printer. Also Software will be able to  record all reports in disk file or database (SQL, ODBC, DBF) or internet server, HTML and similar  rich text format.

No long  period data or collector will be required for sending data to operator interface for reporting except for  high speed collectors. It will not be necessary to make programming in controller subsystems.  Operator interface will have functions to be used for these purposes and triggering will not be required  for triggering. It will be possible to display real time graphs for several tag and alarm tag information. It will be  possible to view Temporary graphs for real time tag data(instant trend) without requiring to set  historical data which were retrieved before. It will be possible to set/configure trend graphs in graphical display interface and to save this  configuration into a file for loading again. Graphical interface will be able to transfer trend data to .csv  file. Alarm pens will display historical status in line with trend pen history in historical data screen  while access is maintained for historical data. Operator will make single request for certain  date and time for historical data view and all pens including alarm and trend pens will be  configured for getting mentioned time interval. Alarm pens will be able to be shifted in addition to trend pens and alarm status will be able to be  displayed real time.
