5.2.1.6 DataServerResetPriority
You can use the DataServerResetPriority function to reset the priority of a data point to 255,
the lowest priority.
Each NVL data point to be reset must be identified by an <NVL> element within the <Data>
parameter, and each NVC data point must be identified by an <NVC> element. You must
reference the specific data point to be reset by its index number (UCPTindex) or its name
(UCPTpointName) in each of these elements, as shown below.
The new priority level for each data point is established by the value of the <UCPTpriority>
property. Priority levels can be numbered from 0 to 255, with 0 representing the highest
priority and 255 representing the lowest priority. Once the priority level assigned to a data
point has been reset to 255, all applications will be able to write to the value of that data
point.
The priority level specified in the <Data> parameter must be a higher priority than the
current priority assigned to the data point for it to be reset. For more information on priority
levels, see Data Point Values and Priority Levels on page 3-5.
NOTE: You should not attempt to reset more than 100 data points with a single call to this
function.
