The standard point states are:
PTM_NORMAL
PTM_ALARM_HIGH
PTM_ALARM_LOW
PTM_WARNING_HIGH
PTM_WARNING_LOW
PTM_ALARM
PTM_WARNING
PTM_AVAILABLE
PTM_OUT_OF_RANGE
PTM_UNAVAILABLE
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:
PTM_NORMAL_NOACK
PTM_ALARM_HIGH_NOACK
PTM_ALARM_LOW_NOACK
PTM_WARNING_HIGH_NOACK
PTM_WARNING_LOW_NOACK
PTM_ALARM_NOACK
PTM_WARNING_NOACK
PTM_AVAILABLE_NOACK
PTM_OUT_OF_RANGE_NOACK
PTM_UNAVAILABLE_NOACK
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.
Syntax
int PTMAP_fold_ack_state (state, ack_occurred)
PTM_POINT_STATE state;
int ack_occurred;
Input Arguments
