5.1.6.3 Range value

Ranges of values are represented by Range DataType defined in OPC 10000-8. If the Range is an array, then ValueRank, ArrayDimensions, and MaxArrayLength attributes are utilized to indicate an array.

1. A simple range of values

2. EBNF: {0..100}

3. OPC UA : DataType=Range, ValueRank= Scalar (−1)

4. A non-continuous range of values

5. EBNF: {0 .. 100 , 200 .. 300 , 500 , 600 .. 650}

6. OPC UA : DataType=Range, ValueRank= OneDimension (1), ArrayDimensions=4
