The standard point states are:
Whenever an alarm that was generated by Point Management is acknowledged by any source, the Alarm Manager sends notification of that fact to the Point Manager. This information is passed by Point Manager to all PTMAP clients in the PTM_RSP structure.
The additional point states that reflect point acknowledgment are:
This subroutine lets you fold the NOACK state of a point into the standard point state, and create the additional point states. These additional point states are recognized by the expression processor that is used for derived points and for graphic object annunciation.
