5.1 Overview of the Setpoint Profiler
Definitions
A
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.
A
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.
A
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.
