# Configuring an SP profile

An SP The setpoint parameter of an analog point. The desired value of a process variable. Setpoint (SP) is an analog pointparameter, and the value is entered by the operator. The setpoint can be changed any number of times during a single process. The setpoint is represented in engineering units. See SP in the Control Builder Parameter Reference. See also: analog point, parameter, process variable. profile is a time-based program typically used as the set point Also known as SP. The desired value of a process variable. Setpoint (SP) is an analog point parameter, and the value is entered by the operator. The setpoint can be changed any number of times during a single process. The setpoint is represented in engineering units. See SP in the Control Builder Parameter Reference. See also: analog point, parameter, process variable. of a control loop. Each program may be from 2 to 50 segments in length, where each segment of the program may be a ramp or a soak, except the last segment, which must be a soak.

In addition to the main output value, a second analog value is available for each step of the program. This output is a fixed soak value, which may be used as an input to another function or to provide a set point for a secondary 1. A Regulatory Control block whose control input is pushed from another Regulatory Control block. See also: block. 2. The controller (or chassis) in a redundant configuration that would assume primary status and responsibility of the assigned functions if the previous primary controller failed. See also: assigned function, chassis, controller, primary. control loop in the process, such as pressure or % carbon.

A set point guarantee function is provided that holds the program if a process variable Normally abbreviated as PV. An actual value in a process. In the case of an analog point, for example, the PV represents values such as temperature, flow, and pressure. A PV may also be sourced from another parameter or be calculated from two or more measured or calculated variables using a point algorithm. See also: analog point, parameter, point algorithm, PV algorithm, PV clamp, PV period. exceeds a predefined deviation from the set point. The set point guarantee can be selected to be active for the entire program, for soaks only, or for user specified segments.

Up to 1,000 profiles can be created and maintained using the Station Experion's main operator interface. Station presents information using a series of displays. See also: display. HC900 Hybrid controller. and UMC800 Profile Configuration displays.

## To configure an SP profile

1. In Station select Configure>Applications>HC900/UMC800>Set Point Programs>Profile Setup.

   The Profile Selection display opens.

2. Select the profile that you want to configure or modify, or click a blank slot to create a new profile.

3. Click the profile name to load its configuration.

The Profile Configuration display allows all the details of an SP profile to be edited from a single display. Changes made to configuration are applied immediately to the stored profile, but do not have any effect on profiles that are currently loaded into HC900 and UMC800 controllers.

## Program control

Values such as Restart Rate and Loop Segment control the dynamic execution of a program. These values can be shown or hidden using the Show/Hide button.

## Clone a profile

Allows the user to copy all the details of another of the 1,000 stored profiles to the current profile slot. The Name field is not copied and made blank.

## Upload from controller

Allows the user to upload the profile currently loaded in an HC900 or UMC800 SP programmer into the profile slot currently being edited.

## Download to controller

Allows the user to download the current profile or changes to program segments to an HC900 SP programmer, provided the programmer is in the Ready or Hold mode. See the section 'Downloading an SP profile' for information on downloading a profile.
