OPC UA Arrays
OPC UA Arrays
In OPC UA node variable or method argument values can be simple scalars, but they can also be complex, up to three-dimensional values.
One-Dimensional Array
The one-dimensional array node consists of unlimited number values (ie. CDP channels) of similar data type.
Two-Dimensional Array
The two-dimensional array node consists of unlimited number of vectors, that each consists of unlimited number of values (ie. CDP channels).
Note: Note that all vectors should contain the same number of values. CDP calculates OPC UA array size based on the largest vector size. If some vector has fewer values than the largest vector then missing values will be zeros when sending or receiving data.
Three-Dimensional Array
The three-dimensional array node consists of unlimited number of matrices, that each consists of unlimited number of vectors, that consists of unlimited number of values (ie. CDP channels).
Note: Note that all matrices should contain the same number of vectors of similar size. CDP calculates OPC UA array size based on the largest matrix size. If some matrix has fewer vectors than the largest matrix then missing vector values will be zeros when sending or receiving data.
