In the initial display, characters that overflow thetemporary input field are disregarded.• Even if the number of digits of a temporary input field is larger than the numberof digits of the objective input field on the base screen, the temporary input fieldcan be used to input a character string. In this case, however the input character string will overflow the character string input field on the base screen andthe overflowing characters are ignored.• A temporary input field is not displayed if an input field does not exist on thebase screen.343SectionInput of Numeric Values and Character Strings3-7Inputting a Character String Using Input Key – String on the Same ScreenThe following describes the basic character string input procedure — inputting acharacter string to a character string input field using the input key – string andinput key – control provided on the same screen when the screen has only onecharacter string input field.Character string input fieldDisplayNT21InputNT21NT31NT631Reference: It is possible to copy the contents in the character string memory table entry to thecharacter string input field using the touch switch Copy Setting function (page326).When creating a screen using the Support Tool, register the following elementsfor the screen.Setting• Character string input field• Input key – string for touch switchesCharacters registered for labels are used for inputting a character string.Marks can be input by specifying FF20 to FFFFH.• Touch switch input key – control• ENT or(necessary for confirming the input)The following keys can be registered if necessary.• CLR(for clearing the character string being input)• CA(for canceling the input)• BS(for deleting a character located immediately before the input cursor)• DEL(for deleting a character located immediately after the input cursor)• A, "(for moving the input cursor)Reference: The input key – control of 0 to 9 and A to F can be used to input a character string.Operation1, 2, 3...1.
Display a screen that has a character string input field.2. Input a character string using the input key – string.Reference: When the screen has only one character string input field, that input field is specified automatically. It is not necessary to specify it as the active input field.3. Press the ENT key or thekey to confirm the input.When the input is confirmed, the input character string is stored to a character string memory table entry.
Then, the occurrence of a change in the contents of the character string memory table entry is notified to the host via thePT status notify area (page NO TAG).344SectionInput of Numeric Values and Character StringsReference:3-7S If the number of characters of the input character string is smaller than thenumber of characters of the character string memory table entry size, the digits left blank are filled with spaces.S When NT20S or NT30/620 compatible mode is being used, the current screennumber occupies the first word of the PT status notify area and the words containing the updated memory table entry number and PT status notify bits areshifted down one word (page NO TAG).Inputting a Character String Using a Bar Code ReaderThe following describes the procedure for inputting a character string into acharacter string input field using a bar code reader when the screen has only onecharacter string input field.Character string input fieldNT31CDisplayInputBar code readerWhen a bar code reader is used, either of the following methods can be selectedfor confirming the input.• Manual confirmation:Use the ENT key or the key to confirm the input character string.• Automatic confirmation:The input character string is automatically confirmed at the same time the barcode reader reads out the bar code data (character string).Reference:S When Manual is selected for inputting a character string using a bar codereader, the input key – string and input key – control touch switches can beused to correct the bar code data (character string) or add any required character.S Selection of Auto/Manual is made in the settings for the communication conditions of a bar code reader at the System Menu of the PT.S It is possible to copy the contents in a character string memory table entry to acharacter string input field using the touch switch Copy Setting function (page326).SettingWhen creating a screen using the Support Tool, register the following elementsfor the screen.• Character string input fieldIf a bar code reader is used in Manual, the following touch switch input key –string and input key – control may be set if necessary.• Touch switch input key – stringCharacters registered for labels are used for inputting a character string.Marks can be input by specifying FF20H to FFFFH.• Touch switch input key – control• ENT or(necessary for confirming the input)345Input of Numeric Values and Character Strings• CLR• CA• BS• DEL• A, "Section3-7(for clearing the character string being input)(for canceling the input)(for deleting a character located immediately before the input cursor)(for deleting a character located immediately after the input cursor)(for moving the input cursor)Reference: The input key – control of 0 to 9 and A to F can be used to input a character string.Operation1, 2, 3...Reference:1.
Display a screen that has a character string input field.2. Read out the bar code data using a bar code reader and input the read outdata as a character string.S When the bar code reader is used with Auto, the input character string is confirmed at the same time the bar code data is read out. If the screen has otherinput fields (numeral or character string), the active input field shifts to the nextinput field automatically.S If the screen has only one input field and that input field is a character stringinput, input of a character string automatically starts when a data is readthrough a bar code reader. (Specification of an objective input field is not necessary.)3. When the bar code reader is used with Manual, press the ENT key or thekey to confirm the input.When the input is confirmed, the input character string is stored to a characterstring memory table entry.
Then, the occurrence of a change in the contents ofthe character string memory table entry is notified to the host via the PT statusnotify area (page NO TAG).Reference:S If the input character string is smaller than the number of characters of thecharacter string memory table entry, the surplus part is filled with spaces.S When NT20S or NT30/620 compatible mode is being used, the current screennumber occupies the first word of the PT status notify area and the words containing the updated memory table entry number and PT status notify bits areshifted down one word (page NO TAG).346SectionUsing the Alarm List/History Function3-83-8Using the Alarm List/History FunctionThis section describes how to use the alarm list and the alarm history, whichmonitor the status of bits in the host and, if a bit status changes to 1 (ON), displaythe corresponding message and the image/library data.The alarm list/history can be checked using the System Menu of the PT.
It is alsopossible to check them during operation by registering them to the screen as anelement (alarm list can only be used as an element.).The Support Tool can read out the alarm history record data stored to the PT tothe host as a text file. For the procedure for reading the alarm history record data,refer to the NT-series Support Tool Version 4.6 for Windows Operation Manual(V061-E1-j).3-8-1 How to Use the Alarm List/HistoryAn alarm list can only be displayed as an element while an alarm history can bedisplayed on a confirmation screen that is called from the System Menu as wellas displayed as an element.Confirming during Operation as an ElementThe status of the bit to be monitored (alarm list) and the record of bit status transition (alarm history) can be confirmed while the PT is operating.Alarm ListMessage (character string table entry 32)set for bit memory table entry 14Character string table entry 32Image/librarydata 113CNo.13BitCharacter string table entry 32Image/library data 113CNo.14Character string table entry 54Image/library data 1125No.15010Character string table entry 50Image/library data 1002HOSTA000000L001003D010015←1(ON)When the message displayed is pressed, the image/librarydata (113C) set for bit memory table entry 14 is displayed.Alarm HistoryMessage (character string table entry13) set for bit memory table entry 24Recorded dataCharacter string table entry 13Character string table entry 12Image/librarydata 102BCharacter string table entry 11 No.
