Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.1 Getting Started Read This Attention Information in this section is a primer to information presented later in this book, and is fundamental to the Profit® Optimizer displays. Read this section carefully. If you are unfamiliar with control basics, such as controllers, process models, and loops, read Section 1 before trying to digest the information in this section.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.2 Control Concepts You Need to Understand 1.2 Control Concepts You Need to Understand Know the Name to Own the Concept The Profit Optimizer displays use control terms that might be new to you. If you are unfamiliar with these terms and the concepts they represent, how Profit Optimizer goes about its control tasks might remain unnecessarily obscure to you.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.2 Control Concepts You Need to Understand CV, MV, and DV BVD, CC Statuses The status of a variable indicates its operating state or condition, what the controller is doing with it. The status is a window into the controller to see how the controller is using the variable, or what confidence the controller has in the variable as a control value.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.2 Control Concepts You Need to Understand MV Modes There are two modes you can set to tell a controller how to use the output of an MV: RMPC, OPR. Table 1-3 explains how the controller uses the output of an MV for these modes. Table 1-3 MV Modes Mode RMPC The variable is available for Profit Optimizer control. OPR MV adopts the configured status: FFWD or SERV.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.2 Control Concepts You Need to Understand How Profit Optimizer Computes Control Moves These are the calculations Profit Optimizer uses to formulate its output: • Prediction Calculations These calculations track the disturbance variables in the process as well as the results of previous control moves to predict where the process is going.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.2 Control Concepts You Need to Understand Parameters The Profit Optimizer uses parameters in its calculations that define optimization objectives and refine optimization decisions. Most parameters are entered through the Profit Optimizer displays (some are entered through the off-line build). For our purposes, there are three kinds of parameters: configuration parameters, tuning parameters, and optimization parameters.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.3 How to Read the Profit Optimizer Displays 1.3 How to Read the Profit Optimizer Displays Fields and Targets Fields and targets are reserved areas on a display, dedicated to a particular purpose or kind of information. In this respect fields and targets are much the same.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.3 How to Read the Profit Optimizer Displays Example Display Figure 1-1 shows fields and targets on a typical Operator display. Discussion following the sample display tells you how to use the screen to display specific information about a Profit Controller.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.3 How to Read the Profit Optimizer Displays Key Access Level The standard Profit Optimizer package applies one of two access levels to targets on Profit Optimizer displays: OPERator or ENGineer. By default, the SUPVR (Supervisor) access is the same as Operator. Responsibility that typically falls to Control Engineers (tuning, for example) is given ENG access.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.4 The Optimizer Bar 1.4 The Optimizer Bar Defined The Optimizer Bar displays near the top of the screen and shows the name of the current (selected) optimizer, the optimizer mode, and the optimizer state. Current Optimizer Current Optimizer Mode Current Optimizer State The Optimizer Bar displays on every Profit Optimizer screen except on the main menu.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.4 The Optimizer Bar Optimizer Modes The optimizer mode establishes the personality of the optimizer. Modes are set through touch-screen targets. Table 1-7 explains the three optimizer modes. Table 1-7 Optimizer Modes Mode Description The normal operating state. In this state, Profit Optimizer optimizes the process. 1/00 • Pressing OFF takes Profit Optimizer off-line from the process.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.4 The Optimizer Bar Optimizer Status The optimizer status indicates internal conditions about the optimizer. There are 12 controller statuses that display as a read-only field as part of the Optimizer Bar. Table 1-8 describes what information the status tells you about the optimizer. Table 1-8 Optimizer Statuses Description Status CONTOL ABORT, SEE MSGS Optimization error encountered.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.5 The Menu Bar 1.5 The Menu Bar Defined The Menu Bar is a row of 10 named buttons for calling Profit Optimizer screens. The Menu Bar displays at the bottom of every screen. Selecting a button calls the named display. Displaying Profit Optimizer Screens Some displays do not have a button on the Menu Bar and must be called by selecting targets on other, higher level displays.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.6 Profit Optimizer Display Structure 1.6 Profit Optimizer Display Structure Number and Purpose of the Profit Optimizer Displays The Profit Optimizer interface comprises 18 displays.

These messages indicate conditions about Profit Optimizer software and optimizer. Error messages remain on the messages display as long as the error is in effect.
Section 1 — An Operator’s Quick Tour of Profit Optimizer Displays 1.8 How to Inactivate the Optimizer Point 1.8 How to Inactivate the Optimizer Point Important! Engineers Read This! Shut the Optimizer Off First Use the Optimizer Bar – Select OFF [ENTER] Always shut Profit Optimizer OFF from the Optimizer Bar before setting the point INACTIVE. Not doing so has consequences for the current Profit Optimizer, and can have consequences for other Profit Optimizers on the LCN.
