5.2.1.7 DataServerDelete
You can use the DataServerDelete function to remove a data point from the Data Server.
Each NVL data point to be deleted must be identified by an element within the
parameter, and each NVC data point must be identified by an element. You
must reference the specific data point to be deleted by its index number (UCPTindex) or its
name (UCPTname) in each of these elements, as shown below.
The deletion of NVL data points requires two steps. NVL data points must be deleted from
L
ON
M
AKER
before they are deleted with this function. When you delete a local NV using
L ON M AKER , the status of the associated NVL data point in the Data Server will be set to
AL_CONSTANT. In version 1.0 of the SOAP/XML interface, the index number of the
associated NVL data point was also increased by 5000 to prevent errors from occurring when
other applications attempt to reference the deleted data point before it is removed from the
Data Server. In version 1.1, the incrementation of the index is no longer necessary.
NOTE: You should not attempt to delete more than 100 data points with a single call to this
function.
