Resolution of  each graph will be within 0,1% of full scale when more than tag is graphed, graph regarding with each  tag and relevant information will be displayed with different color. Trend view will support both analog and digital pen in same graph. Trend pen assignment will be able  to be defined for easily creating and managing frequently used trend groups and will be accessible  while software is running. 32 pens which can be adjusted as samples with 1 second period and which can make report upto  10.000 points with time intervals which can be defined by users by software will be viewed in each  trend graph. Graph will be able to view all trend history for certain pen group in single screen. More than one pen belonging to same pen or drawing trend should be able to be created over several  temporal periods. Separate intervals and engineering units will be displayed in each pen. Each pen will be independent  from other pens to be viewed in page and will be able to be scaled for viewing. Progress can be made backward or forward in certain time interval by using software and exact value  of tag will be able to be read by selecting a point over table. System will monitor historical data by  moving backward with desired time period and it will be viewed in average 1 second together with all  necessary information. There will be sliding bar which will be moved over page in trend screen for  viewing trend date, time and trend tag value when it is intersected with trend tags. Trend screen will be dynamic, will be able to be shifted in time it will have the property to be  displayed again and historical data will be able to be shifted in addition to existing data. There will be  property to stop automatic shifting for detailed analysis of certain data in historical data. Pens which  are present in same windows will be able to be separated in time and interval axis. User can switch from local hour to UTC time in trend screen. When it is in local hour, switch from  summer hour application will clearly be expressed in trend screen. Software will have zoom and pan property for both trend tag interval and time axis interval. Zoom  allows compression and extending axis interval by operator and pan will allow operator to go origin of  axis. Software will allow user to determine a zoom area by dragging mouse within axis. Software will provide minimum, maximum and average summaries for all viewed analog pens. Trends which were retrieved and stored with respect to events instead of periodically will be able to be  viewed in both time axis and with respect to number of event. Software will be able to monitor 32 tags in single trend screen. Tags will be able to be distinguished by different colors. Raw data and time/date values will be able to  be taken from screen or one trend or trend group or detailed analysis. Software will be able to transfer trends, historical data to disk files or external databases. Part of trend  to be transferred will be able to be defined by clicking mouse or dragging cursor inside trend. Data  will be able to transferred to files in .csv, .dbf or .txt format. Any part of historical data will be able to  be sent over ODBC, DDE, dbf, CSV and TXT formats. Software will allow printing trends based on historical data in trend plotters. Software will have  feature to print out trends(not screenshot). Trend printing function will use objects instead of bitmaps  while printing. Trend printouts will include engineering units and intervals for each trend, trend grid  8_Vol3_d4.3_Section 8 electrical works_en_GIR.rev8.doc
