Detailed Description#

This is the Qt OPC UA representation for the OPC UA AxisInformation type defined in OPC UA 1.05 part 8, 5.6.6. It contains information about an axis which can be used for multiple purposes. A common use case could involve the plotting of display data. The engineering units and the title are used for the text on the plot, range, axisScaleType and axisSteps provide the scaling and the axis ranges of the plot.

__init__()#

Default constructs an axis information with no parameters set.

__init__(arg__1)

Parameters:: arg__1 – QOpcUaAxisInformation

Constructs axis information from rhs.

__init__(engineeringUnits, eURange, title, axisScaleType, axisSteps)

Parameters:

engineeringUnits – QOpcUaEUInformation
eURange – QOpcUaRange
title – QOpcUaLocalizedText
axisScaleType – AxisScale
axisSteps – .list of double

Constructs axis information with engineering units engineeringUnits, range eURange, title title, scaling axisScaleType and axis steps axisSteps.

axisScaleType()#

Return type:: AxisScale

Returns the scaling of this axis, defined by AxisScale .

setAxisScaleType()

axisSteps()#

Return type:: .list of double

Returns specific values for each axis step.

This value is empty if the points are equally distributed and the step size can be calculated from the number of steps and the range. If the steps are different for each point but constant over a longer time, there is an entry for each data point.

setAxisSteps()

axisStepsRef()#

Return type:: .list of double

Returns a reference to the axis steps.

eURange()#

Return type:: QOpcUaRange

Returns the lower and upper values of this axis.

setEURange()

engineeringUnits()#

Return type:: QOpcUaEUInformation

Returns the engineering units of this axis.

setEngineeringUnits()

__eq__(rhs)#

Parameters:: rhs – QOpcUaAxisInformation
Return type:: bool

Returns true if this axis information has the same value as rhs.

setAxisScaleType(axisScaleType)#

Parameters:: axisScaleType – AxisScale

Sets the axis scale type to axisScaleType.

setAxisSteps(axisSteps)#

Parameters:: axisSteps – .list of double

Sets the axis steps to axisSteps.

setEURange(eURange)#

Parameters:: eURange – QOpcUaRange

Sets the lower and upper values of this axis to eURange.
