The percentage value is always displayed as5-digit value: the sign character, 3-digit numerical value, and % character. (Thesign character is a blank space for positive values.)162Section 2-10GraphsDisplay SignCircleWhen Display Sign is ON, center position of the meter (It depends on DisplaySign) will be 0%, and the each end side corresponds to 100% and –100%.• When the value is more than 100%, it will be displayed same as 100%.• When the value is less than –100%, it will be displayed same as –100%.When Display Sign is OFF, 0% position and 100% position will be the same.• When the value is less than 0%, it will be displayed same as 0%.• When the value is more than 100%, it will be displayed same as 100%.Overflow display is not performed for both cases.Semi-Circle, QuarterWhen Display Sign is ON, center position of the meter will be 0% and the eachend side corresponds to 100% and –100%.When Display Sign is OFF, from end to end of the meter correspond to 0% to100%.For both cases, Needle or Fill is displayed outside of the meter to indicate thatthe value is outside the range (overflow display) when the value is more than100% or less than –100%.
In this case, frame position will not be tiled with Filltype. Therefore, when Frame is OFF, there will be a 1 dot interval when showingthe overflow display.centerneedle5_Display Method of the Area Between the Present Value and the 0% ValuePresent value of an analog meter is displayed using needle or fill as a displaytype. If you specify needle, the present value is showed as a needle, if you specify fill, the area between 0% and the present value will be tiled in selected foreground color.<Fill><Needle>Meter display colorMeter display color0%0%Clock wiseClock wise–Area display color+Area displaycolor–100% 100%–Area display color+Area displaycolor–100% 100%Donut-shaped Analog Meter (Width Rate)Specify the meter width of an analog meter in % format (0% to 100%) regardingthe radius as 100%.
If you specify a value that is less than 100%, a donut-shaped163Section 2-10Graphsanalog meter will be drawn.Default value for width rate is set to 100%. With default status, therefore, donutshaped analog meter will not be drawn since there will be no inner circle.Scale Distance and Scale LengthSpecify the scale position and scale length in % format regarding the radius as100%.Scale distance (0% to 150%):Specify the distance from the center of an analog meter in % format regarding the radius as 100%.0%None (Scale appears from center point of an analog meter)50%Scale appears inside the analog meter.100% Scale appears on circumference of an analog meter.110% Scale appears 10% outside the circumference of an analog meter.Scale length (10 to 110%):Specify the length from the scale position in % format regarding the radiusas 100%.No.
of Divisions: Specify the number of divisions in which the scale shouldbe divided for the range from 0 to 100%.Since it specifies the number of divisions in which the scale should be divided, No. of Division +1 scale lines are drawn.Also, when Display Sign is ON, the same number of scale lines are drawnboth for –100% to 0% and 0% to 100% range. Therefore, for –100% to 100%range, designated No. of division x2 is applied.Example) No. of Division =Display Sign is OFFCenterWidth rateRadiusDisplay Sign is ONScale lengthCenterWidth rateScale lengthRadiusScale distanceScale distanceDisplay FunctionsAnalog meters indicate numeric values in accordance with the General settings.For details on the method of display depending on the General settings, refer toCommon Attributes (page 159).Input FunctionsAnalog meters have no input functions.Output FunctionsAnalog meters have no output functions.2-10-3 Broken Line GraphsFunction OutlineBroken line graphs represent the contents of multiple consecutive numeralmemory table entries as one broken line.
They enable the values of consecutivenumeral memory table entries to be taken in at a glance.It is possible to display more than one broken line graph in the same frame sothat they can be compared.100%0%–100%164In this example, the values in 11 numeral memorytable entries are displayed with the sign indicated.Section 2-10GraphsWith broken line graphs, a 100% value, 0% value and –100% value can be setfor each broken line in order to calculate and display the numeral memory tablevalues in percentage terms. However, there are no percentage displays for individual numeral memory table entries.Restrictions• One broken line graph frame can be registered for one screen.
(Same for window screen.) For an overlapping screen comprising 8 child screens, up to 8broken line graph frames can be displayed on one screen. Total maximum of256 broken lines can be registered for one screen regardless of the number offrames. (Same for window screen.)There is no restriction on the number of broken line graph frames that can beregistered for one screen data file: any number can be registered as long asthe data file capacity is not exceeded. However, if a large number of elements are registered, check that the restrictions on element display arecomplied with by referring to Display Restrictions (page 437).• The contents of up to 320 consecutive numeral memory table entries (up to260 for the NT21) can be displayed in one broken line.Common AttributesThe relationship between the properties of a broken line graph and the displayresults is indicated below.PropertiesGeneral (properties of the frame)PositionCoordinates of the top left corner of the graph area.SizeWidth and height of the area in which the broken line graph isdisplayed (dot units)NT21:Width 2 to 260; Height 2 to 140NT31/NT31C:Width 2 to 320; Height 2 to 240NT631/NT631C: Width 2 to 640; Height 2 to 480FrameWhether or not a frame is displayed for the graph areaCheck mark (frame displayed)/No check mark (frame not displayed)Display SignWhether or not a negative area is displayed.Check mark (displayed)/No check mark (not displayed)DirectionDirection in which numeral memory table contents aredisplayed in the broken line graph (smaller number → largernumbers) (Direction of broken line graphs, page 167)Up/Down/Left/RightColorFrameDisplay color of the frame (Colors other than black and white areavailable with the NT31C and NT631C only.)Black/Blue/Red/Magenta/Green/Cyan/Yellow/White+ RangeDisplay color of the positive range (Colors other than black andwhite are available with the NT31C and NT631C only.)Black/Blue/Red/Magenta/Green/Cyan/Yellow/White– RangeDisplay color of the negative range (Colors other than blackand white are available with the NT31C and NT631C only.)(effective only when a check mark is set for Display Sign)Black/Blue/Red/Magenta/Green/Cyan/Yellow/White165Section 2-10GraphsSettings (properties of each broken line)Start TableEntry*1First numeral memory table entry number of the numeralmemory table entries used to display the broken line.Range: 0 to 1998No.
