public bool HasError { get; }

Property Value

bool

IsSteady

Gets a value indicating whether the value is steady.

public bool IsSteady { get; }

Property Value

bool

Remarks

Configure the filter (CoE object 8000:11), steady state window (CoE object 8000:29) and the steady state tolerance (CoE object 8000:2A) for an optimal result.
