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.
