The ValueIterator object is used to retrieve historical values for a point in a VHS service. Iteration can move forward or backward through the list depending on how the object was initialized. The order of the values is the order of their timestamps. This order can be viewed in the VHS pane of CygNet Explorer by right-clicking a point and choosing View Values.
Declare the object using the following code:
|
CreateObject("CxVhsLib.ValueIterator") |
