Screen number 9020 isnotified to the host.This makes it possible to use the Programming Console function even inthe RUN mode.(However, the Programming Console function can be used only when thePT is connected to a PC that can use the Programming Console function.)The RUN mode is cancelled while the programming function is beingused.
Also, monitoring of PT control area, data logging function for trendgraphs, alarm history monitoring, and mathematical functions are not131SectionTouch Switches2-7executed. To return from the Programming Console function, exit thisfunction, by PT operation. (It is not possible to exit this function from thehost.)• Screen No. 9021, 9022, or 9023The Device Monitor function’s screens are displayed. The displayedscreen’s screen number (9021 to 9023) is notified to the host. (Thesescreen numbers are not supported by the NT21.)The Device Monitor function can be used even in RUN mode, although thisis the case only when the PT is connected to a PC that can use the DeviceMonitor function.The PT can continue operating even when executing the Device Monitorfunction. The PT continues monitoring the status of the PT status controlarea, logging trend graph data, and monitoring the status of the alarm history.When resetting from the Device Monitor function, either terminate the Device Monitor function with operations at the PT or switch to another screenby executing a PT status control area operation from the host.• Screen No.

The OFF characterstring will be copied if the ON/OFF switching type is specified.
Also, only the firstline will be copied if there are multiple lines of guide characters. If the length ofthe source string exceeds 40 characters, only the first 40 characters will be copied.Reference:S Input into character string input fields is also possible using the control keytouch switches (0 to 9, A to F), and from a bar code reader connected to the PT.S A control key touch switch (ENT or) is also necessary to confirm input character strings when character string setting is used.Control Code Input FunctionControl keys are used as numeric keys (0 to 9, A to F) for the numeral input function, and as special keys with fixed functions. By assigning an control key to atouch switch, it can be used to execute a specific function.The attributes for control keys are as follows:SettingsControl keySet control keyThe following functions can be set for touch switch control keys.KeyFunction0 to 9, A to FUsed to input numerals (1 digit)CLRClears numeric values and character strings in input fields"Assigns the opposite sign to input numeric values.Used to input a decimal pointHOMEUsed to move to the input field at the top left of the screen↑, ↓, ←, →Used to move to the required input fieldConfirms input without shifting to another input fieldStops the buzzer,Shift between input fieldsMENUUsed to display the System MenuCACancels text inputBSDeletes the numeral or character immediately preceding theinput cursorDELDeletes the numeral or character at the input cursor locationA, "Used to shift the input cursorENTConfirms input (after confirmation, the cursor shifts to the nextinput field)Pop-up Window/Keyboard FunctionThis function is used to control the opening and closing of windows when usingthe window function (2-15 Window Function, page 237).133SectionTouch SwitchesReference:2-7S When the window opening bit of the PT status control area is set to 1 (disabled), it is not possible to open windows by operations at the PT such astouch switch operations.S By associating windows with the cursor moving key touch switches with theSupport Tool, windows can be opened by pressing the cursor moving keys.S It is not possible to control a global window by touch switch operation.The attributes for the window key are as follows:SettingsScreen No.Local 1(Keyboard)Local 2Window PositionXYAction TypeReplace LocalWindowCheck this attribute when the local window 1 is to becontrolled.S Specify the screen number of the window to becontrolled.1 to 3999Check this attribute when the local window 2 is to becontrolled.S Specify the screen number of the window to becontrolled.1 to 3999X coordinate of bottom-left corner (multiple of 20)0 to 240NT21:NT31/NT31C:0 to 300NT631/NT631C: 0 to 620Y coordinate of bottom-left corner (multiple of 20 - 1)19 to 139NT21:NT31/NT31C:19 to 239NT631/NT631C: 19 to 479Controlling method of the windowOpen/Close/ToggleSpecify the behavior of the window when the otherwindow of the same type (Local 1/Local 2) is alreadyopened.Check mark (replace)/No check mark (no replace)The window behaves as follows according to the settings for Action Type andReplace Local Windows:Behavior According to the Action TypeOpen: Opens the specified window by the specified type (local 1 or local 2).Whether or not the window is actually opened depends on the displaystatus and the setting for Replace Local Window.The window is displayed at the position that is specified with the WindowPosition setting.If the other window of the same type is already opened, the behavior isdetermined according to the setting for Replace Local Window.If the specified window does not exist, no operation is performed.Close: Closes the specified window of the specified type (local 1 or local 2).When the close window key is pressed, the specified window that ispresently displayed by the specified type is closed.If the specified window is not displayed by the specified type, no operation is executed.Toggle: Opens or closes the specified window of the specified type (local 1 orlocal 2).If the specified window is not displayed by the specified type, the specified window is opened in the same way as the Open window key.Whether or not the window is actually opened depends on the displaystatus and the setting for Replace Local Window.The window is displayed at the position that is specified with the WindowPosition setting.134SectionTouch Switches2-7If the other window of the same type is already opened, the behavior isdetermined according to the setting for Replace Local Window.If the specified window does not exist, no operation is performed.If the specified window is already displayed by the specified type, thewindow is closed in the same way as Close window key.Behavior According to the Replace Local WindowCheck mark:If the other window of the same type is already displayed, thedisplayed window is closed first, and then the specified windowis opened.No check mark: If the other window of the same type is already displayed, nooperation is performed.Copy Key FunctionThis function is used to copy the data or constants in a memory table entry toanother memory table entry or an input field.
It is useful for setting numeral/character string displays to their initial state, and for inputting the same contents (e.g.initial values) into multiple numeral/character string setting input fields.Copying is possible between the following combinations.Copy SourceCopy DestinationNumeral memory table entryNumeral memory table entryNumeral setting input fieldCharacter string memory table entryConstantReference:Character string memory table entryCharacter string input fieldNumeral memory table entryNumeral setting input fieldS It is also possible to copy between memory table entries by operation with thePT status control area.S If the contents of a numeral/character string memory table entry have beenchanged by operation at the PT such as use of the copy key the change is notified to the PT status notify area at the host.135SectionTouch Switches2-7The attributes for the copy key are as follows:SettingsCopy FromTypeType of copy sourceNumeral table entryString table entryCodeMemory TableEntryNumber/FixedValueCopy source memory table entry number, or value if aconstant@ For a numeral/character string memory table entry0 to 1999@ For a constant–2147483648 to 2147483647Copy ToTypeType of copy destinationNumeral table entryString table entryCursor Position (numeral/character string input field)Memory TableEntry NumberMemory table entry number of the copy destination(setting ineffective if Cursor Position is set for Copy To)0 to 1999Cursor Moving Key FunctionThis function moves the cursor to a pre-designated numeral/character string input field in preparation for input.It is also possible to open a designated window simultaneously with the cursormotion, and to automatically display a window in accordance with the input field.Reference:S Cursor moving keys can also be created automatically when a numeral/character string input field is registered on a screen.S Input fields can also be designated using the input key – control.136SectionTouch Switches2-7The attributes for the cursor moving keys are as follows:SettingsUse Window/Keyboard ScreenOpen window/keyboard?Check mark (open)/No check mark (do not open)Screen No.Local 1(Keyboard)Screen number of the window/keyboard to be opened(setting effective only if a check mark is set for Local 1(Keyboard) of Use Window/Keyboard Screen)1 to 3999Local 2Screen number of the window to be opened (settingeffective only if a check mark is set for Local 2 of UseWindow/Keyboard Screen)1 to 3999Window PositionXX coordinate of bottom-left corner (multiple of 20)0 to 240NT21:NT31/NT31C:0 to 300NT631/NT631C: 0 to 620YY coordinate of bottom-left corner (multiple of 20 - 1)19 to 139NT21:NT31/NT31C:19 to 239NT631/NT631C: 19 to 479Replace LocalWindowDesignate the behavior when other window of thespecified type (local window 1/local window 2) is alreadyopenedCheck mark (replace)/No check mark (do not replace)Auto ArrangeMove together with the input field associated in editing atthe Support Tool?Check mark (yes)/No check mark (no)• Settings and action type of window to be used when using Use Window/Keyboard Screen is same as the input key-window/keyboard function that hasOpen action type.Refer to Window Key Function (page 133).Window Moving Key FunctionThis function moves a window by pressing a window moving key, which is preregistered on a window, while the PT is running.Window moving key can be registered on a window screen.Reference:S Window can be moved also by the operation of window control area.
