5.1  Overview of the Setpoint Profiler 
Definitions 
profiler is a Setpoint Profiler function block.  This function block is what you interact with when you 
program and run a profile.  The profiler is analogous to a compact disk player on a stereo, in that the 
profiler “plays” a profile.  Your instrument contains 1, 2, 3, or 4 profilers, depending on the option 
ordered. 
profile is a series of ramp and soak segments, along with any parameters associated with those 
segments, such as segment loops, events, and guaranteed soak enables.  The setpoint produced by 
the profile is used by a control loop’s Setpoint #2.  A profile is also known as a curve or recipe.  A profile 
is analogous to a compact disc, in that the profile is “played” by the profiler.  Your instrument contains 1, 
2, 3, or 4 profiles, depending on the option ordered. 
program is a set of one to four profiles, depending on the instrument.  Programs in a single profile 
instrument contain 1 profile, programs in a two-profile instrument contain 2 profiles, programs in a three-
profile instrument contain 3 profiles, and programs in a four-profile instrument contain 4 profiles. 
Guaranteed soak is a set of parameters that hold the profiler when the deviation between the generated 
setpoint and either PV is larger than a configured limit. 
Event outputs are discrete output parameters of the Setpoint Profiler function block.  They may be tied 
to other function blocks such as Discrete Outputs. 
Profile features 
Each profile has the following features: 
• 
A second PV is available.  Each PV is monitored for excessive deviation from the profile value, in 
which case the profiler can be automatically put on Hold. 
• 
Menu or discrete control of profile resetting, starting, holding, advancing, shutting down, or fast 
forwarding through the profile. 
• 
Discrete input for starting the profiler at the current value of the process variable.  Known as “hot 
start.” 
• 
Discrete input for enabling/disabling guaranteed soak over the entire profile.
