SingleData

The SingleData display type is one of the most basic yet critical indicator types used in SCADA and operational dashboards for presenting a single (scalar) value in the simplest and clearest possible way. The purpose is not to draw a chart, but to answer the question “What is the current value?” with the shortest possible perception time.

Basic Display Logic

142 MW

A single numerical value is displayed in a large font, with clean typography and, when required, together with its unit. There is no chart, trend, or complex visual layer; the focus is on the principle of pure information + fast perception.

CURRENT GENERATION 142 MW Single value • Unit • Fast operator perception

What Types of Data Is It Used For?

SingleData is particularly suitable for instantaneous measurements, meter readings, and calculated KPIs. When the value itself is sufficient for decision-making, presenting it directly without unnecessary graphical layers helps keep the operator screen simple.

  • Instantaneous generation power: 142 MW
  • Daily total generation: 3.48 GWh
  • Active alarm count: 27
  • Plant availability: 96.2%

Basic Components

  • Main Value (Value): Displayed in a large and prominent format; it can be presented together with the unit or separately.
  • Unit (Unit): Defines the physical or operational unit such as MW, %, bar, °C, or MWh.
  • Title (Title): Explains what the value represents, such as “Current Generation” or “Active Alarms.”

Use in SCADA and Energy Systems

Application Area Example SingleData Values
Power Generation Facilities Net generation (MW), plant load ratio (%), daily / monthly energy (MWh)
Switchyards & Distribution Energized line count, busbar voltage, number of breakers open / closed
Thermal & Gas Power Plants Boiler pressure, fuel consumption rate, NOx and CO emission values

7SegmentDisplay

7SegmentDisplay is a display type in which numerical values are presented using the classic digital counter and panel aesthetic. It is particularly useful in SCADA and industrial monitoring screens where instantaneous measurements and meter readings need to be perceived in a sharp, fast, and direct manner.

Digital Counter Approach

000123.45

7SegmentDisplay simulates the principle of forming digits using 7 individual LED segments. Rather than creating an analog-gauge impression, its primary objective is direct numerical reading.

What Types of Data Is It Suitable For?

  • Meter readings
  • Accumulated values
  • Instantaneous measurements requiring precise reading

Examples

  • Total energy: 000123.45 MWh
  • Instantaneous active power: 148.7 MW
  • Operating time: 12 345 h
  • Production count: 000789

Use in SCADA and Energy Systems

  • Power Generation Facilities: Daily / monthly energy generation, total operating hours, net meter readings
  • Switchyards & Distribution: Energy import / export meters, breaker operation counts
  • Thermal & Gas Power Plants: Fuel consumption meters, total steam flow, emission measurement meters

14SegmentDisplay

14SegmentDisplay is an enhanced approach to the 7-segment display. In addition to numerical values, it allows digits 0–9, letters A–Z, and a limited set of symbols to be displayed more clearly. This makes it possible to present a short status or label within the same digital visual language when required.

Value + Text + Status

UNIT-A 148.7

The main advantage of the 14-segment approach is that, compared with a 7-segment numerical display, it provides better rendering of letters and short text.

What Types of Data Is It Suitable For?

  • Meter readings
  • Accumulated values
  • Instantaneous and precise measurements
  • Values that need to be displayed together with short status labels

Use in SCADA and Energy Systems

  • Power Generation Facilities: Energy generation, operating time, and net meter values
  • Switchyards & Distribution: Import / export meters and breaker operation counts
  • Thermal & Gas Power Plants: Fuel consumption, steam flow, and emission meters

16SegmentDisplay

16SegmentDisplay is a more advanced version of the classic digital-panel approach represented by 7- and 14-segment displays. Because it can display letters, numbers, and symbols more flexibly, it is better suited to presenting status + message + value information within the same visual language in SCADA and industrial dashboards.

More Flexible Digital Panel Display

READY 148.7 MW

The 16-segment approach can be designed to display not only numerical values, but also short status messages and symbols in a more readable form.


What Types of Data Is It Suitable For?

  • Meter readings and accumulated values
  • Instantaneous and precise measurements
  • Short status messages
  • Operational screens where status + value information must be presented together

Use in SCADA and Energy Systems

  • Power Generation Facilities: Daily / monthly energy, operating time, net meter readings
  • Switchyards & Distribution: Energy import / export meters, breaker operation counts
  • Thermal & Gas Power Plants: Fuel consumption, total steam flow, emission meters

Combined Evaluation of Display Types

The common purpose of these four display types is to allow the operator to read a value quickly. The difference lies in whether the information is presented as only a numerical value, using a classic digital segment aesthetic, or in a form that also includes short text and status information.

Display Primary Purpose Best Use Key Feature
SingleData Display a single value in the simplest possible form Instantaneous measurement, KPI, alarm count Minimal and fast perception
7SegmentDisplay Present a numerical value in the form of a classic digital counter Meter and precise numerical readings Sharp 7-segment aesthetic
14SegmentDisplay Display letters and short text in addition to numbers Value + short label / status Improved character rendering
16SegmentDisplay Present value + status + message information more flexibly Operational digital panel Most flexible classic segment approach

Basic selection principle for operator screens: SingleData can be considered when the value itself is sufficient; 7SegmentDisplay for numerical measurements where a digital-counter appearance is preferred; 14SegmentDisplay where short text or status information is required; and 16SegmentDisplay where a more flexible status + message + value presentation is needed.

Real-Time Updating with Live Data

The actual value displayed by these indicators on a SCADA screen comes not only from visual design, but from transferring up-to-date process information to the display through Live Data. When the value changes, automatically reflecting the new value on the screen allows the operator to monitor the current process condition without manually refreshing the page.

  • Automatic updating: The display value can be updated as the data changes.
  • No manual refresh required: The operator does not need to reload the screen.
  • Real-time operational monitoring: Generation, meter, alarm, and equipment values remain current.
  • Decision support: Operator evaluation can be based on current process data.

Example: If instantaneous generation power is displayed as 142 MW on SingleData and the current value increases to 148 MW, the display can automatically reflect the new value. This keeps the focus on the current operating value without creating a chart.

Usage Approach in SCADA Screens

SingleData and segment-based displays can be considered not so much alternatives to large charts as fast information layers that complement them. Especially on main operator screens, displaying a few critical values in a large and clear format makes it easier to understand the current process condition before moving to detailed trend or analysis screens.

  • Generation and consumption values
  • Plant load and availability ratios
  • Active alarm / event counts
  • Energy and fuel meters
  • Operating times and operation counters
  • Busbar voltage, pressure, temperature, and similar instantaneous measurements

Note: The display examples presented here are intended to explain the usage logic of the indicator types. Whether a particular display type is actually available in the relevant EOS LIVE DASH version depends on the supported features, data binding, and visualization capabilities of that version. If a display approach is not currently supported, it may be developed in the future.
