Specialized system programs can be installed that allow theNT31/NT31C or NT631/NT631C to be controlled from other companies’ Sequencers. (The NT21 does not support PCs made by other companies.)Multiple WindowsUp to 3 windows can be displayed simultaneously in the normal display. A9-word window control area has been allocated in the host; the contents of these9 words can be changed from the Host to open, close, and move windows.5SectionFunctions of the NT21, NT31/NT31C and NT631/NT631C1-21-2-2 Comparison between NT21, NT31, NT31C, NT631, and NT631CNT21The NT21 models are shown in the following table.ItemNT31/NT31CModelsNT21-ST121-E (Beige)NT21-ST121B-E (Black)DisplaySTN monochrome LCD (with white backlight)Two models are available: the monochrome NT31 and the 8-color NT31C.

The PVs of severalwords can be listed with the device monitor.Interlock FunctionPT operations and inputs can be disabled from the PC if interlock bits have beenallocated in the PC for the corresponding PT touch switches, numeric inputs, orstring inputs.Improved Lamp/TouchSwitch Guide CharactersThe following displays can be performed with lamp or touch switch guide characters:• Display several lines of guide characters.• Switch the display between different guide characters when OFF and ON.• Display numeral memory table contents as guide characters.• Display string memory table contents as guide characters.NT30/NT30C, andNT620S/NT620C/NT625CCompatibleThe word configuration of the PT status control area and PT status notify areacan be set to emulate those of the NC20S, NT30/NT30C, or NT620S/NT620C/NT625C; this mode is called NT20S or NT30/620 compatible mode.When the PT is operating in a compatible mode, it will be equivalent to anNT20S, NT30/NT30C, or NT620S/NT620C/NT625C in the functions listed below.
The PT retains full V2 functionality in all functions other than the ones listedbelow. Refer to Appendix C NT20S and NT30/620 Compatible Modes for moredetails.• Word configuration and functions of the PT status control area and PT statusnotify area• Image/library codes• Insertion of image/library data into character stringsAdditional CS/CJ-seriesPC Data AreasAccessibleData areas in CS/CJ-series PCs that were previously inaccessible can be accessed. The data areas listed below can be accessed (read/written) through a1:N NT Link with the CS/CJ-series PC. (These areas cannot be accessedthrough a Host Link connection.)All banks in the EM Area, Timer Completion Flags (TU), Counter Completion Flags (CU), Work Area (WR), Task Flags (TK), and the HR Area.Recipe FunctionYou can set the data (numeric values) for multiple words in record units using thetabular elements on the PT screen, and write these settings in a single operationto words on the host (i.e., PC or PT memory) using a touch switch operation onthe PT Unit.
Also, multiple words of numeric data can be read from the host inone operation. In this way, groups of parameter settings can be edited at the PTUnit, and written to or read from the host.Adjusting Contrast andBrightness During PTOperationYou can display the brightness and contrast adjustment screen using either thetouch switch or commands from the host, even while the PT is in operation.7SectionFunctions of the NT21, NT31/NT31C and NT631/NT631C1-21-2-4 Comparisons with Earlier ModelsComparison between NT20S and NT21ItemNT20SNT21NT Support Tool usedNT-ZJCAT1-EV4 or NT-ZA3AT-EV2NT-ZJCAT1-EV4Effective display area112 x 56 mm (horizontal x vertical)117 x 63 mm (horizontal x vertical)Screen dots (resolution)256 x 128 dots (horizontal x vertical)260 x 140 dots (horizontal x vertical)Number of touch switches12 x 6 (horizontal x vertical)13 x 7 (horizontal x vertical)DIP switch settingsOn rear of UnitNone (software settings)Use of Memory UnitNot possiblePossible (transferring system programdata and screen data)RS-232C interfaceConnector (9-pin) also used as port forscreen data transfer.- Serial port A connector (also usedfor screen data transfer, 9-pin)- Serial port B connector (for hostcommunications only, 9-pin)Backlight life expectancy10,000 hours min.50,000 hours min.Replacement BacklightNT20S-CFL01Replacement not possibleBattery backupNonePossible*1 (numeral table, string table,history data, recipe data)System program dataInstalled in PT (not replaceable)The system installer and system program data are supplied with the NTSupport Tool.1:N NT LinksStandard onlyStandard or high-speedMemory LinkNotpossible*2Number of user-registered screensMaximum of 500Maximum of 3,99996 KB512 KBNumeral/character string tableMaximum of 128 entries eachMaximum of 2,000 entries eachBit memory tableNoneMaximum of 1,000 bitsMathematical tableNone256 entries max.Calculations can be executedautomatically in the PT.Image dataNoneMaximum of 4,095 (224 for compatibility with NT20S)Library dataNoneMaximum of 12,288 (896 for compatibility with NT20S)Graphic figures (rectangles, polygons, circles/ovals, sectors, filling)None65,535 total per screen, including otherfixed objectsImage library displaysNone256 per screen max.Analog metersNone50 per screen max.Trend graphsNone1 per screen max.Broken-line graphsNone1 per screen max.Alarm lists/historyNone4 per screen max.Recipe functionNone1 per screen max.WindowsNone3 per max.Method for storing numeric values(numeral memory data and PT Status Control Area)BCD (binary-coded decimal)BCD (binary-coded decimal) or binaryPT Status Control Area size4 words5 words (partial change of contents)(4 words for compatibility with NT20S)PT Status Notify Area size3 words2 words (partial change of contents)(3 words for compatibility with NT20S)Screen datacapacity*3Possible(User program memory)8SectionFunctions of the NT21, NT31/NT31C and NT631/NT631CItemNT20S1-2NT21Window Control Area sizeNone9 wordsClock Data Area sizeNone4 wordsRegistering continuous screensPossibleNot possible (Use screen switches asa substitute.)System tenkeyPossibleNot possible (Use normal tenkey as asubstitute.)Lamp/Touch switch labelsFixed display (1 line only)-Interlock functionNoneOperations can be disabled from thePC by allocating interlock bits to thecorresponding touch switch, numeralinput, character string input,thumbwheel switches, or recipeobjects.Programming Console functionNot possible.Possible.Bar code reader connectionNot possible.Possible.High-quality font displayNot possible.Possible.Character codesCP437 (DOS)CP437 (DOS) or ISO8859/1 (Windows)Accessible CS/CJ PC data Areas---The data areas listed below can beaccessed in addition to the data areasaccessible with the NT20S.*4- EM banks (EM_0 to EM_C)- Timer Completion Flags (TU)- Counter Completion Flags (CU)- Work Areas (WR)- Task Flags (TK)- HR Area (HR)*1:*2:*3:*4:Multiple lines can be displayedON/OFF switching is possibleNumeral display is possibleCharacter string display is possibleThe Battery is optional.The NT20S-ST128 supports RS-232C communications commands instead of memory links.This is the capacity of the flash memory that stores screen data.These data areas are accessible only when the PT is connected to the CS/CJ-series PC in a 1:N NT Link.
