This figure calls out the areas on the MPC SimulatePro interface.
Mode Simulation
Use this area to change the MPCPro block mode (mode is displayed Target/Actual).
Controls
Use the slider to set the execution multiplier which scrolls the time scale continuously, and set the number of steps by which the time scale scrolls in step mode. The process is speeded up by the multiplier. (For example, a multiplier of 10 speeds up the process by a factor of 10.) Use the Pause button to examine the trends when the time scale is scrolling in continuous mode and the Continuous Mode (Run) button to continue scrolling.
Double-click the number of steps field to set the number of block executions for step mode. (The default number of steps is the time span for the future area.) Use the Step Mode button to advance the time scale based on the number of steps. For example, if the number of steps is 2, the block executes twice and the time scale advances 2 seconds.
Click the Status button to open the MPC Diagnostics program. Use this application to examine simulated diagnostic parameters.
In the Optimizer field, click the down arrow and select an Optimization Objective.
Trend Tab
Trend Tabs provide access to up to eight trend windows that plot the function block input and output parameters. Up to six inputs and outputs can be trended at one time on a trend window. Click to configure the trends on each tab.
Trend Graph
The trend graph plots the real-time and historical process data collected on a parameter reference. Up to six inputs and outputs can be trended at one time. To add or delete a parameter from the graph, check or clear the check box on the parameter's small faceplate. You can scroll the graph time scale forward and back in time, increase and decrease the time span, and expand and compress the amplitude of a trend line.
Future Trends
The yellow area on the graph displays future (projected) trends for Controlled and Constraint variables.
Legend
The Legend provides information about the parameter references and helps you to read the graph. Right-click a parameter in the Legend to modify the Y axis and scale, change the trend color and plot method, and scroll the trend forward and backward in time.
Large Faceplate
Use the large faceplate view to make changes in operating targets of Controlled or Manipulated parameters, to open a Detail picture to change limit and tuning parameters for each MPCPro parameter, and to add noise and other unmeasured load disturbances and test their affect on the process.
Small Faceplates
Up to 40 small faceplates (20 inputs and 20 outputs) can display in the small faceplate area. The small faceplates can be made larger or smaller allowing the operator to view more faceplates at once. Select the command to make the faceplates the smallest size and deselect the command to make the faceplates the larger size. Click a small faceplate to view the for that parameter reference.
Disturbances
Use this area to add noise and other unmeasured load disturbances to test their affect on the process.
