Buffering on an API Node

The tag attribute shutdown should be modified to be FALSE for remotely collected and buffered points and the default home node PI\dat\shutdown.dat file should use a tag attribute mask of shutdown,1 as shown here.

! shutdown.dat: Shutdown for server points.

! login info - no longer used - ignored.


! tag mask


! tag attribute selection (logical AND for all attrib)

! point attributes,value to select points receiving shutdown


This will ensure that the points collected by the remote API node will never have shutdown written by the PI Server. The program collecting the data is responsible for writing the status indicating that the API node was shut down, such as "Intf shut" or "I/O timeout".
