The Automation Tank is a tile for a tank, or for a battery, that shows how full it is. It is found in the Automation - OpenBridge section of the Perspective Component Palette as Automation Tank (Beta).

Note: This component is in beta: its properties may change in a later version.

1. Tag — the name of the tank. See Tag.
2. Badges — small icons in the top right corner. See Badges.
3. Percent and trend — how full the tank is, with a symbol for whether the level is rising or falling. See Level and Trend.
4. Value and capacity — the content and the capacity, with a unit.
5. Chart — a bar, or a graph of the level over time. See Chart.

The tank shows the values it is given; it does not read tags or alarms itself, and clicking it does nothing unless you configure an event.

An Automation Tank dropped from the palette with default properties:

Level

Bind value to the content of the tank and set max to its capacity, in the same unit. The tank shows both numbers, the percentage value is of max, and a bar filled to that percentage. A value above max is shown as 100 %.

The unit is m³. For another unit, set hasCustomUnit to true and write the unit in unitText.

value = 640, max = 1000	unitText = L

Decimals

The numbers are shown without decimals. valueFractionDigits and maxFractionDigits set the number of decimals of the content and the capacity, and percentFractionDigits that of the percentage.

valueFractionDigits = 1, maxFractionDigits = 1	percentFractionDigits = 1

value and max can also be texts. A text is shown exactly as it is written, which lets you format the number yourself, for example with a decimal comma. The bar and the percentage are then calculated from the number the text starts with: 640,3 counts as 640, and 1 000 counts as 1. Use a text only when the number in it is written without spaces.

Properties

Name	Description	Property Type
value	Content of the tank: a number, or a text that is shown as written. Default 0.	value
max	Capacity of the tank: a number, or a text that is shown as written. Default 100.	value
valueFractionDigits	Number of decimals of the content. Applies when value is a number. Default 0.	value
maxFractionDigits	Number of decimals of the capacity. Applies when max is a number. Default 0.	value
percentFractionDigits	Number of decimals of the percentage. Not used by the compact layout. Default 0.	value
hasCustomUnit	Use unitText as the unit instead of m³. Default false.	value
unitText	The unit. Default m³. Only shown when hasCustomUnit is true.	value

---

Trend

trend selects the symbol in front of the percentage. The tank does not work out the trend itself: bind trend to an expression that compares the level with an earlier one. Set showTrendSymbol to false to hide the symbol.

trend
fast-rising
rising
stable (default)
falling
fast-falling
closed

Properties

Name	Description	Property Type
trend	fast-rising, rising, stable, falling, fast-falling or closed. Default stable.	value
showTrendSymbol	Show the trend symbol. Default true.	value

---

Tag

tag is the name of the tank, shown in the top left corner. It is empty by default, as in the image of the default properties above.

Properties

Name	Description	Property Type
tag	Name of the tank, for example FW Tank 1. Empty by default.	value

---

Type

type selects the outline of the tile, which tells what kind of tank it is. Set hasGraphIcon to true to also draw an icon on the chart: a battery for the battery type, a tank for the others.

type	hasGraphIcon = false	hasGraphIcon = true
generic (default)
atmospheric
pressurized
battery

Properties

Name	Description	Property Type
type	generic, atmospheric, pressurized or battery. Default generic.	value
hasGraphIcon	Draw a tank or battery icon on the chart. Default false.	value
medium	normal, empty, water or air. Default water. Has no visible effect.	value

---

Layout

orientation places the chart below the numbers (vertical) or beside them (horizontal):

vertical (default)	horizontal

Set compact to true for a small tile with only the chart, the percentage and the tag. The content, the capacity and the detail rows are not shown.

Compact	Compact, horizontal

Set static to true for a tank whose level is not known: the tile is grey and shows only the capacity and the tag. static takes precedence over compact.

Static	Static, horizontal

Properties

Name	Description	Property Type
orientation	vertical or horizontal. Default vertical.	value
compact	Small tile with chart, percentage and tag only. Default false.	value
static	Grey tile that shows only the capacity and the tag. Default false.	value

---

Positioning

positioning decides how the tank is placed in the component’s box. The blue frame in the images is the component’s box, as the Designer shows it when the component is selected:

positioning
button (default)
point

• button — the tank fills the box. Resize the component to resize the tank. The text keeps its size, so a small box leaves little room for the chart; a new component is 168 × 173.
• point — the tank has a fixed size and ignores the size of the box: 256 × 376 (170 × 282 when compact or static, 420 × 256 when horizontal, 244 × 208 when both). The middle of its top edge is placed on the top left corner of the box, 20 px above it in the layouts that are not compact. Use it when the tank must hang from a fixed point in a diagram.

Note: point works differently here than on the automation buttons, where the point is the top centre of the box.

Properties

Name	Description	Property Type
positioning	button fills the component’s box; point hangs a tank of fixed size from the top left corner of the box. Default button.	value

---

Chart

chartMode selects what the chart shows:

• bar (default) — a bar filled to the level.
• graph — a graph of the level over time, from chartData.
• graph-and-bar — the graph, with a narrow bar for the current level at its right edge.

chartMode	vertical	horizontal
bar
graph
graph-and-bar

chartData holds the points of the graph, on the same scale as value and max. It can be:

• a dataset, for example from a tag history binding. The first date column (or else the first column) is the time, and the first other column that is not a date is the level;
• an object with two lists of equal length, xValues and yValues;
• a list of objects with a value each.

priority selects the colour of the bar and the graph. Use enhanced for the tank the operator is working with:

regular (default)	enhanced	enhanced, graph-and-bar

Advice

Advice zones mark ranges of the level on the chart, for example the range the tank should be kept in, or a range to stay out of. Set hasAdvice to true and add one item to advice for each zone, with its limits on the same scale as value. The limits are drawn as dashed lines across the bar, and the zone as a mark on its right edge.

advice and caution zones	The same zones, hinted	With graph-and-bar

Properties

Name	Description	Property Type
chartMode	bar, graph or graph-and-bar. Default bar.	value
chartData	The points of the graph: a dataset, an object with xValues and yValues, or a list. Empty by default.	object
priority	Colour of the bar and the graph: regular or enhanced. Default regular.	value
hasAdvice	Show the advice zones. Default false.	value
advice	The advice zones. Empty by default.	array
advice[].min	Lower limit of the zone. Default 0.	value
advice[].max	Upper limit of the zone. Default 10.	value
advice[].type	advice or caution. Default advice.	value
advice[].hinted	Draw the zone mark as an outline instead of filled. Default false.	value

---

Detail Rows

readout is a list of extra measurements of the tank, such as temperature and pressure. Each item gives one row between the numbers and the chart, with a label, a value and a unit. The rows are shown in the regular layout only, not when the tank is compact or static, and they need a taller box: the image is 168 × 230.

numberFormat of a row is a Java DecimalFormat pattern. Only the digits after the decimal point are used; they set the number of decimals: 0.0 shows 21.5, 0.00 shows 1.20, and both #,##0.## and 0.00 show 1234.567 as 1234.57. No thousands separator is added.

Properties

Name	Description	Property Type
readout	The detail rows. Empty by default.	array
readout[].label	Text in front of the value. Default Label.	value
readout[].value	The number. Default 0.	value
readout[].unit	Text after the number. Empty by default.	value
readout[].hasDegree	Show a degree sign between the number and the unit. Default false.	value
readout[].numberFormat	DecimalFormat pattern that sets the number of decimals. Default #,##0.	value

Clickable and Activated

With clickable set to true, the tank is a button: it is highlighted while the pointer is over it, and it can be reached with the keyboard. Set it to false for a tank that only shows data. Nothing happens on a click in either case until you configure an onClick event.

Set activated to true to show a highlighted background behind the tank. Use it to mark the tank as selected, for example while its faceplate is open. It works only while clickable is true.

Properties

Name	Description	Property Type
clickable	Draw the tank as a button, with a hover state. Default true.	value
activated	Show the activated (selected) background. Needs clickable. Default false.	value

---

Badges

The tank has the same four badges as the automation buttons, with the same properties and values: badgeControl, badgeAlert, badgeInterlock and badgeCommandLocked. They are described in Badges. On the tank they are drawn in a row in the top right corner, in that order:

---

Alert Frame

Set alert to true to draw an alert frame around the tank. The properties are those of the automation buttons, described in Alert Frame, with these differences:

• There is no alertFrameMode: the frame is always steady and does not flash.
• showAlertIcon has no effect, as the tank has no property for an icon of your own.
• The properties are shown in the property editor also while alert is false.

alertFrameType
regular
small-side-flip (default)
large-side-flip
bottom-flip
top-flip

alertFrameStatus
level-critical
level-high
level-medium
level-low
level-diagnostic
alarm (default)
warning
caution

Properties

Name	Description	Property Type
alert	Show the alert frame. Default false.	value
alertFrameType	Shape of the frame: regular, small-side-flip, large-side-flip, bottom-flip or top-flip. Default small-side-flip.	value
alertFrameStatus	Colour and icon: a level-* value, alarm, warning or caution. Default alarm.	value
alertFrameThickness	small or large. Default small.	value
showAlertCategoryIcon	Show the icon of the alert status in the flap. Default true.	value
showAlertIcon	No effect. Default false.	value

Properties

Name	Description	Property Type
style	Standard Perspective style object.	object

The colours follow the OpenBridge palette of the session:

Component Events

The Automation Tank has no component events of its own. The standard Perspective events, such as onClick, are available in the component’s event configuration.

Examples

Example 1 — Fresh Water Tank with Trend

1. Drop an Automation Tank into the view.

2. Set tag to FW Tank 1 and max to the capacity of the tank, for example 1000.

3. Bind value to the content of the tank, for example [default]Tanks/FW1/Volume.

4. Bind trend to an expression on the rate of change of the level, for example:

   if({[default]Tanks/FW1/Rate} > 0.5, 'rising', if({[default]Tanks/FW1/Rate} < -0.5, 'falling', 'stable'))

Example 2 — Level History as a Graph

1. Set chartMode to graph-and-bar.
2. Add a Tag History binding to chartData for the tag of the content, for example [default]Tanks/FW1/Volume, with the time range you want to show and the return format Dataset.

Example 3 — Battery

1. Set type to battery and hasGraphIcon to true.
2. Set hasCustomUnit to true and unitText to kWh.
3. Set max to the capacity of the battery and bind value to its charge, both in kWh.
