Which of these methods is used is determined by the setting made for communication port A with the memory switches of the SystemMenu (Set Bar-Code Reader, then set automatic confirmation or manual confirmation for Comm. Setting.)Outline of OperationThe basic operation of a character string input field is shown below.1, 2, 3...1. Input a character string into a character string input field using touchswitches or a bar code reader.
The input text is inserted at the position of theinput cursor.PTCharacter string input fieldDisplayNT21InputNT21NT31NT6312. Confirm the input character string with the ENT key or touch switch: it willbe written to a character string memory table entry (when the input modefrom a bar code reader is set as automatic confirmation, the character stringis automatically confirmed on input).At this time, the occurrence of a change in the contents of the characterstring memory table entry is notified to the host via the PT status notify area.The writing of character string data to a character string memory table entry,and notification to the host, are not automatically executed merely by displaying a character string in a character string input field.
Writing and notification are executed when the ENT key or key touch switch is pressed.PTData writingNT21NT21Restrictions210NT31NT631NotificationNT21Character stringmemory tableentryHost• A maximum combined total of 256 of the following elements can be registeredfor one screen. (Same for window screen) Even in the case of an overlappingscreen with eight child screens, it is only possible to register character stringinput fields on one of the child screens.Section 2-13Inputting Character StringsCharacter string input fieldThere is no restriction on the number of input fields that can be registered for onescreen data file: any number can be registered as long as the data file capacity isnot exceeded. However, if a large number of elements are registered, check thatthe restrictions on element display are complied with by referring to Display Restrictions (page 437).• It is not possible to set character string input from more than one characterstring input field on the same screen to one character string memory tableentry.• The following numbers of characters can be displayed in one character stringinput field, depending on the scale.NT21NT31/NT31CNT631/NT631C1 1 (Equal)MagnificationUp to 32 charactersUp to 40 charactersUp to 40 characters1 2 (High)Up to 32 charactersUp to 40 charactersUp to 40 characters2 1 (Wide)Up to 16 charactersUp to 20 charactersUp to 40 characters2 2Up to 16 charactersUp to 20 charactersUp to 40 characters3 3Up to 10 charactersUp to 13 charactersUp to 26 characters4 4Up to 8 charactersUp to 10 charactersUp to 20 characters8 8Up to 4 charactersUp to 5 charactersUp to 10 characters• The characters that can be displayed are alphanumerics, symbols and Marks.Marks are displayed at the standard height even if Half Height is set as the FontType.
Therefore, if normal alphanumerics and symbols are displayed after displaying a mark, part of the mark will remain displayed, as shown in the figurebelow.• If Half Height is set for Font Type, and a character string is written after displaying Marks, a part of the Marks will remain displayed, as shown below.Aa bBc Cd eDf gEh i jIn this case, create blank characters as marks, write these marks, and thenwrite the alphanumeric and symbol character string over them.• It is not possible to register multiple input fields that refer to the same stringtable entry on the same screen.Reference: When the PT is in NT20S or NT30/620 compatible mode, marks, image codes,and library codes can also be input.
Refer to Appendix C for details on the NT20Sand NT30/620 compatible modes.211Section 2-13Inputting Character StringsCommon AttributesThe relationship between the properties of a character string input field and theinput and displayed character string is indicated below.PropertiesGeneralPositionCoordinates of the top left corner of the character stringinput fieldFont TypeFont for the charactersStandard/Half HeightScaleScale at which the character string is displayed (Enlargeddisplay, page 151)1 1 (Equal), 1 2 (High), 2 1 (Wide), 2 2, 3 3,4 4, 8 8SmoothingWhether or not smoothing is used for characters with ascale of 2 2 or larger (Smoothing, page 151)Check mark (smoothing executed)/No check mark (smoothing not executed)AttributeDisplay mode for the text (Display attributes and drawingresult, page 214)Standard/Flash/Inverse FlashColorForegroundDisplay color of the text (Colors other than black andwhite are available with the NT31C and NT631C only.)BackgroundBackground color of the text (Colors other than black andwhite are available with the NT31C and NT631C only.)Black/Blue/Red/Magenta/Green/Cyan/Yellow/WhiteBlack/Blue/Red/Magenta/Green/Cyan/Yellow/WhiteSettingsTable EntryNumber of the character string memory table entry towhich the input character string is to be writtenRange: 0 to 1999LengthMaximum number of characters in the input characterstring1 to 32NT21:NT31/NT31C:1 to 40NT631/NT631C: 1 to 40Focus FramePresence/absence of a frame indicating that the characterstring input field has become ready to accept inputCheck mark (frame present)/No check mark (frame not present)Focus AttributeDisplay status before the input character string isconfirmed (Display attributes and drawing result, page214)Standard/Inverse/Flash/Inverse FlashInterlock FunctionInterlockPresence/absence of interlock control of character stringinputCheck mark (interlock)/No check mark (don’t interlock)PC address settings212PC bit addressAllocated interlock bit used to enable/disable operation ofthe character string input (See Interlock Bit Allocation onpage 213.)I/O commentsComment that explains the allocated bit.Up to 16 characters.Section 2-13Inputting Character StringsPositionForeground colorABCDEBackground colorIf the number of characters actually input is greater than the number of inputcharacters set for the character string input field, the excess characters are ignored.If the number of characters actually input is less than the number of input characters set for the character string input field, the character string is input at the cursor position, and the characters that were to the right of the cursor position areshifted to the right.
Therefore, when a character string with fewer than the setnumber of characters is input, characters that were displayed previously will bedisplayed following this character string. To make these characters blanks, either fill the surplus part with blanks, or use touch switches with the control codeinput function (BS, DEL, etc.) to delete the surplus characters before confirmation.Interlock FunctionA character string input can be controlled (enabled/disabled) from the PC by setting the interlock function for the character string input and allocating an interlockbit in a PC data area. The status of the allocated interlock bit is read and its statusdetermines whether the input is enabled or disabled.The following table shows how the PT operates when the interlock function isused or not used.InterlockfunctionUsedOperationCharacter strings can be input only while the interlock bit is ON.If you attempt to input a character string while the interlock bit is OFF,the buzzer will sound and the input field will not change.When an input is made from a temporary input field to an interlockedcharacter string input while the interlock bit is OFF, the buzzer willsound when the character string in the temporary input field isconfirmed and the destination character string input field will notchange.When an input is made from a bar code reader to an interlockedcharacter string input while the interlock bit is OFF, the characterstring that was read will not appear in the input field and the buzzerwill sound whether manual confirmation or automatic confirmation isbeing used.
The destination character string input field will not change.Not usedCharacter strings can be input and confirmed at any time.The PT continuously reads the status of the corresponding interlock bit while acharacter string input field that uses the interlock function is being displayed onthe screen. if the interlock bit’s status changes, the character string input field isdisabled or enabled according to the interlock bit’s status.Reference: If the touch switch input sound has been turned OFF with the PT’s memoryswitch setting, the buzzer won’t sound when you attempt to input a characterstring in an interlocked input field.Interlock Bit AllocationInterlock bits can be allocated in the following host (PC) areas.SymbolC-series PCsAllocationCV-series PCsAllocationCS/CJ-series PCsAllocationNoneIR AreaOKCIO AreaOKCIO AreaOKHHR AreaOK------HR AreaNot withHost Link213Section 2-13Inputting Character StringsSymbolC-series PCsAllocationCV-series PCsAllocationCS/CJ-series PCsAllocationAAR AreaOKAuxiliary AreaNoAR AreaLLR AreaOK------LR Area*1Not withHost LinkTTC Area,Timer PVsNoTimer Area,Timer PVsNoTC Area,Timer PVsNoTU------------TC Area,Timer Completion FlagsCTC Area,Counter PVsNoCounter Area,Counter PVsNoTC Area,Counter PVsCU------------TC Area,Counter Completion FlagsNot withHost LinkW------------WR AreaNot withHost LinkTK------------Task FlagsNot withHost LinkDDM AreaOKDM AreaOKDM AreaEEM Area *2,current bankOKEM Area,current bankE0_ toEC_---------Not withHost Link---OKNot withHost LinkNoOKEM Area,current bankNot withHost LinkEM Area,EM banks 0 to CNot withHost Link*1: LR 00000 to LR 00199 are converted to CIO 01000 to CIO 01199.*2: The EM Area is supported only by the C200HX/HG/HE(-Z)E PCs.Since the Auxiliary Area of the CVM1/CV-series PCs is allocated to system functions, and it cannot be used for purposes other than system use.The range of each memory area differs according to the PC.
Refer to Appendix DPC Memory Maps on page 441.When a DM Area or EM Area address is specified, add a bit number (00 to 15) tothe end of the word address.Display Attributes and Drawing ResultAttributeStandardDrawing ResultThe character string input field is displayed with thespecified foreground color and background color.ABCDEFGFlashRepeated alternation of the standard display and nodisplay.ABCDEFG ⇔Inverse FlashRepeated exchange of the foreground color andbackground color.ABCDEFG ⇔ ABCDEFGDisplay FunctionsCharacter strings are displayed in the character string input field in accordancewith the General settings.For details on the method of display according to the General settings, refer toCommon Attributes (page 212).214Section 2-13Inputting Character StringsInput FunctionsCharacter strings are input into the character string input field by using the inputkey – string and input key – control touch switches or a bar code reader.For details on the connection and settings of the bar code reader, refer to section3 of the Setup Manual.When a character string input field using the interlock function is being displayedon the screen, the PT continuously reads the status of the corresponding interlock bit allocated in the PC.Output FunctionsCharacter string input fields only write input character strings to character stringmemory table entries; they have no function for directly outputting data to external destinations (if a character string is written to the character string memorytable entry for which words have been allocated in the host, the data can be output to the host indirectly).However, the input of a character string is notified to the host via the PT statusnotify area.Processing FunctionsCharacter string input fields have no processing function.Relationship with Other Elements• Character string displays (page 148) use the same display method as character string input fields.• For details on how character strings are stored in character string memorytable entries, refer to 2-3-2 Character String Memory Table (page 79).• In order to use a character string input field, input and confirmation touchswitches are required, unless a bar code reader is used with the automaticconfirmation setting.
In cases where there is more than one input field,switches for selecting and moving input fields are also required (page 343).• Character string input fields overlap with other elements in accordance withthe order in which they were registered for the screen with the Support Tool.However, the way in which they overlap can be changed with the Support Tool.215Section 2-14Recipes2-14 Recipes2-14-1 Function OutlineYou can write data in table format to the host (PC memory or PT memory), andread data in table format from the host. Use this function to write multiple settingsfrom the PT to the host in a single operation, and to read multiple settings fromthe host in a single operation.• The data in table format (“recipe data”) consists of names and parameters (initial values). You can create multiple recipe data for a single application, andcan use it as a recipe table after storing it in a PT.• Recipe elements consist of the specified data in table format (see above), anddedicated recipe touch switches (Read and Write touch switches, and thescroll touch switches).
