The ManualNumericHistoryExt component provides an action named "Manual Collect" which causes the parent control point's out value to be written to a record in the configured history. The interval value should be configured to match the frequency of the external logic. Note that when executing a "Manual Collect" that at least 1/2 of the configured interval time must have elapsed since the last record was written to the history. This limitation is enforced by the BHistoryExt superclass.
The ManualNumericHistoryExt component is located in the vykonPro palette under the history sub folder.
