Property Value

The default value of this property is -1.

The value rank indicates whether the variable is a scalar, an array, or a matrix. This property converts the count of array dimensions to an OPC UA value rank.

CAUTION: The notion of value rank in OPC UA, and its numeric values, differ somewhat from the traditional understanding of an array rank. For more information, see OpcLabs.EasyOpc.UA.UAValueRanks.

Only the definite value ranks are supported by this property. Indefinite value ranks, i.e. OpcLabs.EasyOpc.UA.UAValueRanks.Any, OpcLabs.EasyOpc.UA.UAValueRanks.ScalarOrOneDimension, or OpcLabs.EasyOpc.UA.UAValueRanks.OneOrMoreDimensions are not supported.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.
