Table 5-2   Parameters That Control Profiler Execution (continued) 

HOLD 

Holds a profiler at its current position.  
Profiler’s Elapsed Time continues but 
Segment Time stops until Profiler is started 
again. 

Hold is activated by online operator menu or 
by a discrete input. May be connected to F2 
key (SY1F2). 

Level ON 

Profiler is in 
Run or Hold 

Profiler is 
put in Hold 

ADVANCE 

Advances a profiler on Hold to the starting 
value of the next segment.  If the profile is on 
the last segment, it advances to the ending 
value of the last segment.  If the profile is on 
the ending value of the last segment of the 
batch, then it advances around to the starting 
value of segment 1, or to the first segment of 
the batch phase as defined by BATCH 
SEGMENT FIRST.  If within a loop, advances 
to next segment in the loop. 

Advance is activated by online operator menu 
or by a discrete input. 

Rising 
edge 

Profiler is in 
Hold 

Profiler 
advances 

HOT START 

When HOT START is ON and the profiler is 
started, the profiler begins to run at the point 
in the profile where the current value of PV #1 
first occurs.  Hot Start makes the profiler skip 
over unneeded segments. 

Hot Start is activated by a discrete input. 

Example 

If PV #1 is 100 and the profile contains the 
value 100 in Segment 4 and Segment 6, HOT 
START forces the profiler to start running at 
Segment 4 at 100, not at Segment 1 or 
Segment 6. 

Level ON 

Profiler is in 
Ready 

When 
profiler 
changes 
from Ready 
to Run, 
profiler 
jumps to 
the same 
value as 
PV #1 

PV#1

Profile starts here

If Hot Start = ON, Profile starts at first intersecting point between profile and PV #1.
