Not only bar graphs but also broken line graphs, trend graphs, and analogue meter graphs can be displayed using numeral memory table entries. Lamp display Lamps can be turned on and flashed under the control of the host. It is also possible to display different graphics in the ON and OFF states. Alarm list/history display Warning messages are automatically displayed in a list in response to the state of a host bit.
Page 31 Device Monitor function (NT31/NT31C and NT631/NT631C) When the PT is connected to a PC in a 1:1 NT Link or 1:N NT Link, the PT can be used for operations such as changing the PC’s operating mode, displaying or changing the PVs of words, or reading the error log.
Page 32: Displays
They can be used as custom characters within character strings. Image data contain graphics comprising any required area of dots. They are reg- istered in advance and as many as required can be displayed at any position on the screen.
Page 33 These are graphics whose display status changes in accordance with the states of bits at the host. Squares, circles, sectors and polygons can be used for lamps (normal (standard) lamps). In accordance with the status of the host bit, they can be lit (displayed in reverse video) or flashed (repeated alternation between nor- mal and reverse video display states).
Page 34 Functions of the NT21, NT31/NT31C and NT631/NT631C Section Touch switches can be made to light or flash in accordance with the status of a host bit in the same way as lamps. The following 8 types of display graphic can be used for touch switches: Stan-...
Page 35 Section String Inputs Character strings can be input at the PT by using touch switches, bar code read- ers, etc. The input character strings can also be stored in a character string memory table entry and notified to the host.

NT30C, NT31, NT31C, NT600S, NT620S, NT620C, NT625C, NT631, NT631C) up to 8 PTs can be connected to one port of the PC and used at the same time. Up to 8 PTs (NT21, NT31, NT31C, NT631, and NT631C) can also be connected simultaneously when the high-speed 1:N NT Link is being used.
Page 45 PT status Notification from the PT Data in the PT is sent to a PC when, for example, a touch switch is pressed. The to the PC following 5 types of data are sent to a PC.
Page 46 Allocate any desired words in the PC for numeral memory table entries. If the contents of the allocated words are changed while the numeral memory table data is being displayed on the screen as numeric values or lamps, the display on the screen will also change automatically. This function allows the contents of allocated words to be monitored easily.
Page 47 Allocate any desired words in the PC to character string table entries. When text is input with a character string input, the new character string will be written to the character string memory table entry and the contents of the words allocated in the PC will be changed automatically.
Page 48 This record data can be displayed as the alarm history. PT Status Control Area The PT status control area is used to control the PT status. When data is written to this area in the PC, the PT reads the contents and operates according to the contents.
Page 49 Each area (PC to and from PT) stores the screen number, and the X and Y coordinates of the lower left corner of the window that is being displayed. When data is written to this area in the PC, the PT reads the contents and executes tasks such as switching the windows to be displayed or moving the position of the windows according to the contents (page 241).
Page 50: Clock Data Area (Pc To Pt) (Nt21 Only)
1-4-5 Clock Data Area (PC to PT) (NT21 Only) The NT21 does not have a built-in clock and instead uses the clock data from the PC. The seconds, minutes, hour, day, month, year, and day of week data is read from the PC into a Clock Data Area.
Page 51: Communication By Using Memory Links
In memory link, there is an area called the PT Memory, as shown below, inside the PT, and this area is treated as a virtual area on the PC. This allows PT memory and the display elements of the PT to make a quasi-direct connection.
Page 52: Memory Link Online Transfer Function
When memory link communications are being used, the PT can be switched to Transmit mode from the host and screen data can be written even if the PT is operating. (The PT can be returned to RUN mode after the screen data is writ- ten.)
Page 53: Before Operating
This operation is not normally necessary. When using other PC models (sequencers), however, it is necessary to install specific system programs. *2: Display of the system menu, and all change operations, can be disabled to prevent the accidental deletion or alteration of screens and settings.

Page 57: Pt Screens
2-1-2 Screen Numbers The screens of the PT are classified and managed by screen numbers. Screen numbers are used to designate the first screen displayed when the PT is started up, and to designate the objective screen when switching the screen dis- play, etc.
Page 58 Both parent screens and child screens can be registered under any screen num- bers in the range 1 to 3999. Note that a new screen must be designated as a parent screen. Parent screen Child screen Screen No.
Page 59 PT also allows screens to be displayed in one part of the screen area only. This partial screen is called a window. and a screen on which a window is displayed is called a window screen.
Page 60 0 can be changed. Screen Name Function No-display screen If screen number 0 is designated as the display screen, the screen of the PT is made blank. 9000 System initializing This screen is displayed during the initial processing when the PT starts operation.
Page 61: Screen Attributes
The backlight is lit. (Default) Flash The backlight is flashed. Reference: The PT’s backlight can also be lit or made to flash using the PT status control bit (page 293). Buzzer The buzzer attribute allows the buzzer to sound when a screen is displayed.
Page 62 (Default) Reference: The display history can be checked in the Maintenance mode of the PT, and can also be read during operation by displaying screen number 9001 (occurrence or- der) or screen number 9002 (frequency order). It is also possible to transmit the display history record data to the personal computer by operation at the Support Tool.
Page 63: Display Colors
(page 157). Reference: XOR is the abbreviation of eXclusive OR. Color combinations that are opposites in terms of the three primary colors — red, green, and blue — are said to be in an XOR relationship. Example: Blue (red 0, blue 1, green 0)
Page 64 Black White (EL lit color) White Reference: When screen data is created for an NT21 or NT31, black and white are displayed as white and black respectively at the Support Tool. Transparent Display When elements are displayed on top of others, normally the background color of the element on top conceals the element below so that it cannot be seen.
Page 65: Display Elements
(Background) Line color Reference: When a lamp, a touch switch, and a graphic are displayed in color, part of the frames of the display elements may be invisible because of the combination of the background, outline, and tiling colors. This is a phenomenon peculiar to a col- or LCD, not a failure of the system.
Page 66 These are graphics that light (flash) and go off depending on the sta- Page 112 lamps tus of a bit at the host. The following shapes can be selected for nor- mal (standard) lamps: rectangles, polygons, circles, fans.

Page 68: Areas For Control/Notification
This area is used to notify the memory table entry number to the host when there is a change in the data contents of a memory table entry in the PT, and to notify information such as changes in the PT status.
Page 69: Pt Status Control Area
In this case, the screen switch setting notification from the PT occurs in the first word (word m) of the PT status notify area. Refer to Appendix C for details on the NT20S and NT30/620 compatible modes.

Page 77: Pt Status Notify Area (Pt To Host)
Alarm History Initialization (Bit 1) This bit is used to initialize the alarm history recorded in the PT. When it is switched from 0 (OFF) to 1 (ON), the alarm history in the PT is initial- ized. After initialization, return its status to 0.
Page 78 PC Memory Maps on page 435. Functions of the PT Status Notify Area Reference: When the PT is set to NT20S or NT30/620 compatible mode, there are 3 words in the PC status notify area instead of 2 words. The added first word indicates which screen is currently being displayed at the PT and the original two words are shifted down.
Page 79 PT Operation Status (Bit 15) When the PT is in RUN mode, this bit is set to 1. In other modes, and when the System Menu screen is displayed, it is set to 0 (OFF). When this bit is set to 0 (OFF), the allocated bits and words are neither read or written.
Page 80 Areas for Control/Notification Section read it 30 seconds later. If the setting for the bit is 1 (ON), the PT is judged to be running, and if it is 0 (OFF), the PT is judged to be stopped. Note To ensure system safety, be sure to periodically read the PT operating status bit from the host in order to ensure that the PT is always operating normally.
Page 81: Window Control Area
Global Window Open Status (Bit 5), Local Window1 Open Status (Bit 4), Local Window2 Open Status (Bit 3) This bit is set to 1 (ON) when a corresponding window is open. It is returned to 0 (OFF) when a corresponding window is closed. (It remains 1 (ON) even if the window screen number is switched in the middle of operation.)
Page 82 The Auxiliary Area of the CVM1 and CV-series PCs is allocated to system func- tions, 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 D PC Memory Maps on page 435.

Page 164: Character String Display
An image or li- brary display might extend beyond the edge of the PT’s screen when it is dis- played by changing the contents of a character string memory table entry within a character string display.
Page 165 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 Font Type. Therefore, if normal alphanumerics and symbols are displayed after dis- playing a mark, part of the mark will remain displayed, as shown in the figure below.

Page 192 With the pen recorder type, the latest drawing position is always displayed at the edge of the graph area. As time passes, the part of the graph that is already dis- played moves in the direction specified by Direction (as if paper were moving underneath a pen).
Page 193 With the PT, the data logging function can be used for the data of up to 8 lines. The maximum data quantity that can be recorded for each is 1440 points, and when this limit is exceeded the data is deleted from the oldest points.
Page 194 The PT will start drawing the trend graph again when it is switched to a screen containing the trend graph from another screen, so use a touch switch that controls the trend graph if you want to display the previous data.
Page 195 The relevant functions are performed once only when the touch switches are pressed. These functions cannot be controlled from the host. The positions of these touch switches can be set freely on the screen. However, the display colors, sizes and the marks cannot be changed.
Page 196 With a standard type trend graph, if this touch switch is pressed during dis- play of the latest data to backtrack to past data, and then the next page (for- ward) touch switch is pressed to return to display of the latest data, the latest data is plotted following the past data.
Page 197 With the pen recorder type, the latest drawing position is always displayed at the edge of the graph area. Therefore, depending on the number of data in the latest page, old data may be displayed discontinuously as shown below (Internally, the data is recorded continuously.)

Page 330: Changing Numeral And Character String Display
Changing the Contents of the Allocated Word of a Numeral Memory Table By allocating a word for a numeral table entry in the host, it is easy to reflect chan- ges made at the word in the host to the numeral memory table.
Page 331: Changing Numeral And Character String Display
Note that the contents of a numeral memory table entry allocated word can only be read out when the memory table entry is being used for an element that is currently displayed by the PT (if the background function is set for a trend graph, the contents of the corresponding word are always read out).
Page 332 Section Program Operation 1, 2, 3... 1. The value 1 is added to the contents of D0000 every second. At the PT, the displayed value of the numeral memory table entry 1 increases by 1 every second. 2. Each time carry over occurs during processing at (1) above, the contents of D0001 are incremented by 1.
Page 333 51 must not be outside the range of 0100 to 0101. By using the lamp bit of the touch switch, it is possible to identify which of the numeral memory table entries is used for display. For details, refer to 2-7 Touch Switches (page 119).
Page 334 Be sure to check the size of the image or library display so that it doesn’t extend past the edges of the screen when it is displayed. (Refer to page 451.) S When the PT reads out the words in a character string memory table entry, it reads the number of words specified in the Words setting.
Page 335 Section Indirect Specification The following shows an example of changing the displayed numeric value by adding a value to the contents of a numeral memory table allocated word that is referenced in indirect specification. Setting at the Support Tool Set as indicated below using the Support Tool.
Page 336 PT Status Control Area If this method is used, contents can be copied between any required memory table entries at any time in response to a command from the host. Note that this method is possible only for the following combinations.
Page 337 Numeral memory table entry: 1 (ON) 3. Set 1 (ON) for bit 3 of the 4th word (word n + 3) from the beginning of the PT status control area. Data copy is executed between the specified type and specified numbers of memory table entries.
Page 338 Changing Numeral and Character String Display Section 4. After the execution of memory table copying, return the setting for bit 3 of the 4th word (word n + 3) from the beginning of the PT status control area to 0 (OFF). Example of Use Setting at the Support Tool Set the word and the contents with the Support Tool as indicated below.

Page 340 This method allows an operator to change the contents of a memory table entry simply by operation at the PT. It is also possible to copy data to a numeral setting/ character string input field by using this method. With the Copy Setting function, data can only be copied in accordance with the predetermined method.
Page 341: Display Of Graphs
When creating the screen using the Support Tool, register a trend graph for the screen and set a check mark for the data logging function, with the setting for displaying special touch switches. The special touch switches will then be auto- matically attached to the screen.
Page 342: Input Of Numeric Values And Character Strings
It is also possible to place the control key used to specify the input field in a win- dow or keyboard screen. Various inputs can be handled by registering control keys in windows according to their type and switching to the desired window when necessary.
Page 343 7 8 9 4 5 6 1 2 3 Input Reference: It is possible to copy a constant or contents in a numeral memory table entry to a numeral setting input field using the touch switch Copy Setting function (page 325). Setting When creating a screen using the Support Tool, set the elements indicated be- low on the screen.
Page 344 Cursor Frame If a Cursor frame is set for the numeral setting input field, the frame that encloses the input field is displayed while the field is accepting input.
Page 345 Initial Operation of Input Keys How the sign () key, the decimal point (.) key, and alphabetic letter (A to F) keys operate in the initial input (the first input after the screen is displayed or after the confirmation of the previous input) is described below.
Page 346 The following describes the procedure for inputting a numeric value at a screen that has multiple numeric key type numeral setting fields. The explanation is giv- en for the operation that uses the input key – control keys to specify the input field instead of the touch switch cursor moving keys.
Page 347 Pressing the HOME key selects the field at the upper left of the screen as the objective input field. If several input fields are arranged at the same distance from the upper left corner of the screen, the one at the left most position is se- lected as the objective input field.
Page 348 Tool, a cursor moving key touch switch can be created overlapping the input field. This enables the input field to be selected to accept input just by pressing it. Here, the basic method for inputting numeric values is not explained: the ex- planation concentrates on how the multiple numeral setting input fields should be handled.

Page 384 SECTION 4 Using Memory Link This section gives an overview of memory link operations and contains explanations centered on communications between the PT and host when using memory link. Operation of the Memory Link ..........
Page 385: Operation Of The Memory Link
With memory link, allocation of element bit or word is performed for PT memory. The PT memory is a virtual PC area within the PT. The PT read/write to the inter- nal PT memory and a host controls/monitors the PT by reading/writing PT memory.
Page 386 Bit memory table clear command Page 388 Notify Commands These commands serve to notify the host of the results of operation at the PT. Only these commands are issued by the PT and, therefore, there is no response for them.
Page 387: Outline Of Communications
The flow of communications between the host and the PT follows one of the three patterns indicated below, depending on the types of command and the set- tings made for response with the memory switches. Refer to section 6 of the Set- up Manual for details.
Page 388: Outline Of Communications
The points that should be observed when using commands are given below. Method for Specifying Commands When a personal computer or similar device is used as the host and a high-level language such as BASIC or C is used for program writing, commands are speci- fied as ASCII character strings.
Page 389 The checksum of the command response is the 2 digits ASCII code that is indi- cated using lower one-byte of the total sum (in unit of bytes) of the following, from the [ESC] code at the beginning to the character immediately before the check- sum value.
Page 390: Commands/Responses
Checksum (2 hexadecimal digits) This is always added. Function Reads the contents of the specified number of words from the specified word of the PT memory. Used to read the statuses of the PT notify area, window control area, lamps, touch switches and bit memory table entries allocated PT memory, and the contents of numeral and character string memory table entries.
Page 391: Numeral Memory Table Read Command (Sent From Host To Pt)
In the response, maximum of 50 words can be returned at one time. If reading of more than 50 words is specified, the response is split into two parts. In this case the first part always contains 50 words of data. Note also that the first word address read in the second part of the responses will be the word address of the first word in the response data.
Page 392: Character String Memory Table Read Command (Sent From Host To Pt)
A maximum of 100 table entries can be read at one time. In the response, the data of maximum of 20 table entries can be returned at one time. If reading of more than 20 table entries is specified, multiple re- sponses are made, each comprising the data of 20 table entries.
Page 393: Bit Memory Table Read Command (Sent From Host To Pt)
A maximum of 20 table entries can be read at the same time. In the response, data is returned in units of one table entry at a time. If reading of multiple table entries is specified, a number of responses equal to the speci- fied number of table entries is made.
Page 394 A maximum of 100 table entries can be read at one time. If a number of table entries that is not a multiple of 16 is specified, 0 is inserted in remaining bits (leftmost bits).
Page 395: Screen Data Comment Read Command (Sent From Host To Pt)
The responses above will be returned when PT is in RUN mode. With the modes other than RUN mode (when RUN indicator is not lit in green), no re- sponses will be returned even if this command is sent. Sending this command enables to know whether or not PT is running by checking the presence/ab- sence of responses.
Page 396: Pt Memory Write Command (Sent From Host To Pt)
PT memory. The result after executing the specified operation (write attribute) on the pres- ent contents of the PT memory and the written data is written is as follows: A maximum of 50 words can be written at one time.
Page 397: Numeral Memory Table Write Command (Sent From Host To Pt)
Contents of the written numeral memory table entries (1 to 8 hexadecimal digits) 0 to FFFFFFFF It is possible to omit initial zeroes so that there are less than 8 digits. Checksum (2 hexadecimal digits) When m is 0 or 8, omit this setting.

Reference: the numeral storage type of the numeral. Numeral storage type can be set at the Support Tool. (It is possible to set it by a system memory at a PT collective- ly.) e.g.) Writing 1234 to the numeral memory table entry 0 (allocated word: 1)
Page 399: Bit Memory Table Write Command (Sent From Host To Pt)
Reference: The maximum number that can be specified for character string memory table entries depends on the setting for numbers of character string table entries (256/1000/2000) made at the Support Tool. However, it is not possible to write to character string memory table entries of numbers higher than No.500 since they are used only as a reading area.
Page 400 A maximum of 100 table entries can be written at one time. If a number of table entries that is not a multiple of 16 is specified, 0 is inserted in remaining bits (leftmost bits).
