Also, be sureto write the library code number in hexadecimal.)Position (top left corner of library data)Size (Y direction)Size (X direction)When an Unregistered Code Is SpecifiedWhen a code for which no library data is registered is specified, the symbol indi) is displayed on the Support Tool, but on thecating an unregistered code (PT nothing is displayed.Input FunctionsLibrary data have no input function.Output FunctionsLibrary data have no output function.Processing FunctionsLibrary data have no data processing function.Relationship with Other Elements• Difference between image data and library dataImage data can take any form for it is composed of dots, but library data canonly be created by assembling fixed display text and graphics.Since only drawing information for characters and graphics is registered forlibrary data, library data requires little memory area in comparison withimage data, which requires all the dots to be displayed on the screen to beregistered as data.Another difference is that flash and inverse display are not possible forimage data, but library data can be displayed in these modes in accordancewith the display attributes of the registered elements.
The timing of the flashing is the same for all elements.• It is possible to specify different image/library data for the graphic displayedwhen a lamp (image/library lamp) is ON and OFF (page 112).• It is possible to specify different image/library data for each message displayedfor the alarm list/alarm history function (page 182).• Library data elements overlap with other fixed display elements in accordancewith the order in which they were displayed. However, the way in which theyoverlap can be changed with the Support Tool.111SectionLamps2-62-6LampsFunction OutlineLamps are graphics that change in accordance with the status of a set bit.
Lampsare classified into the two major categories indicated below.Normal (Standard) LampsNormal (standard) lamps change the display status (OFF/ON/flashing) of fixeddisplay graphics.ONONHostOFF statusON statusImage/Library LampsImage/library lamps display different graphics (image/library data) in the ON andOFF statuses.ONOFF statusHostON statusLamps are arranged and set on the screen when creating screen data with theSupport Tool.RestrictionsCommon Attributes112• A maximum of 256 lamps can be registered for one screen.
For overlappingscreens comprising 8 child screens, the maximum is 1,024.There is no restriction on the number of lamps that can be registered for onescreen data file: any number can be registered as long as the data file capacity is not exceeded. However, if a large number of elements are registered, check that the restrictions on element display are complied with byreferring to Display Restrictions (page 437).• When polygons are used as the display graphics for normal (standard) lamps,one polygon can be given up to 255 vertices.• Image/library lamps are subject to the maximum simultaneous display restriction imposed on image and library data. This means that a maximum total of256 image/library lamps and image and library data can be displayed on onescreen. For overlapping screens comprising 8 child screens, the maximum is1,024.• When library data is displayed with an image/library lamp, if the library dataprojects outside the screen area, nothing is displayed.
Usually, the SupportTool ensures that the data does not project out of the screen area.• If no data is registered for the specified image/library lamp code, nothing will bedisplayed.• Among lamps, the display order is determined by the order in which the lampswere created. However, this order among lamps can be changed with the Support Tool.The common attributes vary widely according to the type of lamp, therefore theyare described separately for each case.SectionLamps2-6Display FunctionsNormal (Standard) LampsThe relationship between the properties of a normal (standard) lamp and the displayed graphic are indicated below.PropertiesGeneralPositionCoordinates of the top left corner of the lamp display areaSizeWidth and height of the lamp display area (in dot units)FramePresence/absence of a frame for the lamp display graphicCheck mark (frame used)/No check mark (no frame)ShapeShape of the lamp (display graphic)Rectangle, Polygon, Circle, SectorColorFrameColor of the frame (valid only when a check mark is set forFrame above).
