SHUTDOWN

When Shutdown is activated by a discrete
input or by the operator menu, the profiler
jumps from the batch phase to the shutdown
phase of a multiphase profile. The shutdown
phase begins at the segment defined by the
parameter BATCH LAST SEGMENT+1.
Shutdown is useful when you need to shut
down your process without waiting for the
profiler to finish a batch.

Example

BATCH FIRST SEGMENT, which specifies the
start of the batch phase of the profile, is set at
Segment 3. The last segment of the batch
phase, BATCH LAST SEGMENT, is set at
Segment 7. The last segment of the profile is
Segment 9. When SHUTDOWN changes
from OFF to ON, the profiler will jump to
Segment 8, the first segment of the shutdown
phase of the profile.
