An OPC Block Element allows reading or writing one of the Elements of an OPC Block where it is inserted.
An OPC Block reads a data table, and this object is always linked to a position defined by its Index property. For example, an OPC Block Element with an Index equal to five and inserted into an OPC Block with a size of 10, whose data is read as on the following table would have its Value property equal to three.
