(Refer topage 312.)S Window moving key can be used only on a local window. It does not function ifthe window screen is displayed as a global window.Window moving key has no special attributes.Moving a Window By the Operation of a Window Moving KeyTo move a window by the operation of a window moving key, follow the procedure below.1, 2, 3...1. Pre-register a window moving key on the window to be moved.2. Press the window moving key on a window to be moved while the PT is running.137SectionTouch Switches2-7The window is changed to the frame display only as follows, with themark at the center of it:Window moving keymove3.
Press the touch panel of the PT at the moving destination.Window is moved so that the center position of the window comes to thepressed position.This time, Display Position of the corresponding window area is changed.movePress the moving destinationWhen the window is in a moving status (whilemark is displayed at the centerof the window), the following points differ from the normal running status.• The elements that use the touch panel as an input do not function regardless of the screens (base/window) they are registered on. Only the specification of the window moving destination is possible.• Switching to the system menu is not possible.• Screen switching or window controlling due to the change in bit memorytable entry, PT status control area or window control area is not possible.• Screen saver function does not work.• There is no time-limit for a window moving status.
It will not return to thenormal running status until the moving destination is specified.Reference:S Window moves by a minimum touch switch size (20 20).S Be sure to complete all the window moving operation when in the window moving status, since its behavior differs from the one when in the normal runningstatus.Screen Print Key Function (NT31/NT31C and NT631/NT631C Only)This function allows starting and stopping of the printing of a hard copy of thecurrently displayed screen (screen image) at a printer connected to the PT.
(Thisfunction is not supported by the NT21.)Reference:S The PT continues operating during printing.S The printer type and printing method (color/monochrome (8 grayscale levels))is determined by memory switch setting at the PT.S A hard copy of the screen can also be printed by operation with the PT statuscontrol bits.
In this case also, printing can be stopped part way through bypressing a touch switch.138SectionTouch Switches2-7The attributes for screen printing are as follows:SettingsPrint ScreenPrinting ofDisplay ScreenSet whether the touch switch is to start printing or stopprinting.Start/AbortRelationship with Other Elements• By using input key – string and input key – control in combination with NumeralInput (page 192) and String Input (page 210), numeric values and characterstrings can be input.Registering these keys in windows makes it possible to switch among windows as required for versatile input.• Special touch switches with specific functions (input key – control) are automatically created for the following elements.Trend graphs (page 170), alarm list (page 182), alarm history (page 182),thumbwheel switches (page 200), recipes (page 216)• Touch switches overlap with other elements according to the order in which theelements were registered on the screen with the Support Tool.139SectionNumeral Display2-82-8Numeral DisplayFunction OutlineThe contents of numeral memory table entries are displayed as numeric values.The values can be displayed either in decimal or hexadecimal notation.There are two methods for referencing a numeral memory table entry whosecontents are to be displayed, as follows:• Direct reference (reference of the number of the relevant numeral memorytable entry)PTPCNumeral memorytable entry 1800620062Allocated word(numeral memory table entry 18)DM01000 0 6 2Directreference• Indirect reference (reference of the numeral memory table entry that stores thenumber of the relevant numeral memory table entry)PCPTNumeral memorytable entry 1877770062Indirectreference7777Numeral memorytable entry 62Allocated word(numeral memory table entry 18)DM01000 0 6 2DM02007 7 7 7Allocated word(numeral memory table entry 62)Restrictions• A maximum of 256 numeral displays can be registered for one screen.
(Samefor window screen.) For overlapping screens comprising 8 child screens, themaximum is 1,024.There is no restriction on the number of numeral displays that can be registered for one screen data file: any number can be registered as long as thedata file capacity is not exceeded. However, if a large number of elementsare registered, check that the restrictions on element display are compliedwith by referring to Display Restrictions (page 437).• The maximum number of numeral display that can be displayed using indirectreference is 100 per screen combined with the number of character string display that is displayed using indirect reference.
(Same restriction applies tooverlapping screens or when displaying window screens.)• The range of numeric values that can be displayed depends on the StorageType (BCD or Binary), Display Type (Decimal or Hexadecimal), and DisplaySign settings made for the numeral memory table entry. For details, refer to 2-3Numeral Memory Table (page 72).140SectionNumeral DisplayCommon Attributes2-8The relationship between the properties of a numeral display and the displayednumeric value is indicated below.PropertiesGeneralPositionCoordinates of the top left corner of the field in which the numericvalue is displayed.Font TypeFont for the charactersStandard/Half Height/Double WidthScaleScale at which the numeric value is displayed (Enlargeddisplay, page 142).1 1 (Equal), 1 2 (High), 2 1 (Wide), 2 2, 3 3, 4 4,8 8SmoothingWhether or not smoothing is used for numerals with a scale of2 2 or larger (Smoothing, page 143).Check mark (smoothing executed)/No check mark (smoothing not executed)AttributeDisplay mode for the numerals (Display attributes and drawingresult, page 142).Standard/Flash/Inverse FlashColorForegroundDisplay color of the numerals (Colors other than black and whiteare available with the NT31C and NT631C only.)Black/Blue/Red/Magenta/Green/Cyan/Yellow/WhiteBackground Background color of the numerals (Colors other than blackand white are available with the NT31C and NT631C only.)Black/Blue/Red/Magenta/Green/Cyan/Yellow/WhiteSettingsReferenceIndirectReferenceMethod for referencing the numeral memory table entry(Direct reference and indirect reference, page 143)Check mark (Indirect Reference)/No check mark (Direct Reference)Table EntryNumeral memory table entry number referenced for display(Direct reference and indirect reference, page 143)4-digit BCD value@ When Direct Reference is specified:Table entry number of the numeral memory table entry inwhich the numeric value to be displayed is stored@ When Indirect Reference is specified:Table entry number of the numeral memory table entry inwhich the number of the numeral memory table entry whosecontents are to be displayed is stored.Display TypeDisplay format for the numeric value (Stored data anddisplayed numeric value, page 144)Decimal/HexadecimalFormat (Number of digits displayed, page 143)IntegerNumber of digits in the integer part of the numeric valueDecimalNumber of digits in the decimal fraction of the numeric value141SectionNumeral Display2-8SettingsZeroSuppressionWhether or not zero suppression is used (Zero suppression,page 144)Check mark (zero suppression used)/No check mark (zero suppression not used)Display SignWhether or not negative numbers are indicated (settingineffective if Hexadecimal has been set for Display Format)Check mark (negative numbers indicated)/No check mark (negative numbers not indicated)PositionForeground color123456Background colorEnlarged DisplayNumeric values can be displayed at the following scales.1 1 (Equal)2 1 (Wide)4 41 2 (High)2 23 38 8With ISO 8859-1 font type, the numerals of 2 2 or larger scale are automaticallydisplayed in 32 dot high-definition font.Reference: The 32 dot high-definition font is not displayed for the following models (16 16dot font is used.)• NT31-ST121j-E• NT31C-ST141j-E• NT631-ST211j-E• NT631C-ST141j-E• NT631C-ST151j-ESmoothingCharacters enlarged to a scale of 2 2 or greater can be displayed with the outline automatically smoothed.
