The DC block is for motor control. Select Modules in the Object Type field. Select MTR and click Open. The MTR module is displayed in the Diagram view.
Enlarge the Control Studio application window to its full size by clicking the Maximize button in the upper right corner. Change the palette to Logical so you can easily access the descriptions for the individual blocks. You can remove the excess condition blocks and their connecting lines by selecting one or more than one and pressing the Delete key. To select more than one, click them while holding the Shift key, or drag a selection box around the whole group.
Place the mouse pointer outside the upper left corner of CND4. Click and hold the mouse button, then drag to include the lower right corner of the CND8 box. If not, click a blank spot and try again. Press the Delete key to delete the selected items. Or click the right mouse button and select Delete from the context menu. Click Yes when asked to confirm the deletion. The blocks and connection lines are deleted.
Now we need a way to specify these requirements. The condition blocks serve this purpose. Each condition will have associated with it an expression that identifies the condition precisely in mathematical or logical terms. Expressions are made up of operands, operators, functions, constants, and keywords.
After you have entered an expression, the Expression Editor checks the syntax, indicates problems, and identifies any unresolved parameters.
The dialog box for the Expression Editor looks like this: The Expression Editor inserts the characters shown in the following table when constructing expressions. If you type the expressions without using the Expression Editor, you need to use these characters in the same way.
Use the Insert Internal Parameter button to browse for these parameters. CV' parameter one within another module. Use the Insert External Parameter button to browse for these parameters.
In Batch processing, used to enclose an alias. The value of the right operand is assigned to the left operand. Transitions use these operators. Click the Arrange Windows button on the toolbar or select Window Arrange Windows so that you can see all the views again. Select the block named CND1. Click the right mouse button and select Expression from the menu to open the Expression Editor.
Click the Insert External Parameter button. This button browses for parameters that are external to the current parameter. Double-click TANK The Expression Editor assembles the tagname and puts it in the Expression box. Type a semicolon at the end of the expression. The expression indicates that an interlock should occur the motor should shut off if the block valve is closed.
A named set is simply a way to define names and equate them to integer values. Click Parse. The Expression Editor checks the syntax. If there are any errors, correct them. AI1 is the analog input function block. CV is the parameter for the analog input current value. The expression indicates that an interlock should occur the motor should shut off if the tank level goes below gallons.
Click Parse, correct if necessary, and click OK. PID1 is the loop function block, and PV. CV is the parameter indicating the current state of the valve percent open. The expression indicates that an interlock should occur if the valve is less than 5 percent open. Parse the expression and click OK. This is the parameter for the run status signal.
This is the output signal from the Discrete Loop block to the field device. Save the control module by clicking the Save button. The module has already been named. Minimize Control Studio by clicking the Minimize button in the upper right corner.
Exercise 8: Creating a Sequential Function Chart Sequential Function Charts SFCs are types of module algorithms that are useful for controlling time-event sequences, such as startup or shutdown of a process. SFCs are made up of steps and transitions. Steps contain a set of actions. A transition allows a sequence to proceed from one step to the next when the transition condition is true.
Each time the SFC scans, the system evaluates the active steps and transitions. When a transition evaluates as True, the step prior to the transition is made inactive and the step following the transition becomes active. There are no predefined module templates for SFCs since process sequences are highly individual. In defining an SFC, you may find it helpful to first define the steps in the process, and then identify the conditions that must be met before proceeding from step to step.
A named set defines names and equates them to integer values. Following is a suggested sequence for the tank discharge application. Step 2: Put the flow loop in auto mode and set the setpoint to 50 gpm. Step 3: Open the block valve. Transition: Confirm that the block valve is open. Step 4: Start the pump. Transition: Confirm that the pump has started. Open or restore the DeltaV Explorer.
Point to Named Sets in the left pane, click the right mouse button and select New Named Set from the context menu. A new entry, NamedSetn where n is the next number available , is added to the end of the list of existing named sets. The entry is in an edit box, ready to be renamed. Type Sequence Control in the description box. Click Add. The State Properties dialog box appears. Note Named sets are case-sensitive. They may be defined using uppercase or lowercase characters, but all future references to the state must be as originally defined.
To add another state, click Add. Click OK to save the set and close the dialog box. Minimize the DeltaV Explorer. Restore Control Studio by clicking its button on the Windows task bar. Click File New. A new SFC diagram opens, with a single step, S1. Click in the Parameter View, click the right mouse button, and select Add from the menu.
Type SP as the Parameter Name. Select Named Set as the Parameter type. The parameter is added to the module. In the Diagram View, select the step box named S1. In the step Action View in the lower right corner , click the right mouse button and select Add. Enter the Step Description: Stop and Wait. For the Action type, select Assignment. This type assigns the result of an expression to a destination.
For the Action qualifier, select Pulse. Thus, the assignment statement is evaluated and the assignment made on the first scan through the step actions when the step goes active.
After the first scan, the assignment destination retains the assigned value; it is not rewritten for each scan. An alternative is to click the Expression Assistant button to open the Expression Editor to define the Action expression. The Expression Editor was used earlier to define the interlock conditions for the motor control module. Click OK on the Properties dialog box. If necessary, make any corrections, and click OK. Giving the step actions meaningful names instead of A1, A2, etc.
A plus sign named T1 appears. Click the right mouse button and select Properties or double-click the transition. Click Parse on the Expression Assistant. Correct, if necessary, and click OK on both dialogs. Repeat the procedures for adding steps and transitions using the information in Table , which follows. Drag-and-drop Step and Transition icons from the palette or use the Sequence item on the palette to automatically add multiple steps and transitions in one operation.
Use a Termination icon for the last transition. The reason is that if Action 2 Step 2 were Pulse, it might not get set because it waits until the actual mode is Auto. It would fail on the first try and never be set. Use the Connect Mode tool to connect the steps and transitions in order. Change the step and transition names by clicking the right mouse button, selecting Rename, and typing the Name listed in the table. Parameter values are enclosed in single quotes.
Close Control Studio by clicking the close button in the upper right corner. If you are working with a controller placeholder, you can assign the modules to the placeholder, but you cannot do a download. There are several different levels of downloads. Note You must load and assign the controller licenses before downloading the modules to the controller.
Loading and assigning licenses is described in Chapter 8. This shows you all the modules you have assigned to the controller. When asked, confirm that you want to proceed with the download. When asked, confirm that you want to check the configuration. A window opens to show you the progress of the download and to let you know when it is complete.
When the download is complete, click Close. You have created the four control modules needed for the tank application and the sequential function chart module for automating the process. In the next chapter you will learn about the DeltaV operating environment and how to create the operator pictures.
Before creating process graphics, you need to understand some things about the DeltaV Operate application—to learn the importance of designing for the operating environment. Important There are a few things you should know and a few rules that you must follow when designing operator pictures.
Pay particular attention to the paragraphs marked Important. If you will be using this application, you will want to become familiar with the full range of features it provides. This tutorial only touches the surface. One very helpful feature is the ability to toggle between the two DeltaV Operate modes: configure and run. While you are creating a picture in configure mode, you can preview the picture in run mode.
This lets you test the elements of the picture, such as links and push buttons, as you create them. The DeltaV Operating Environment It is important to understand the operating environment for a DeltaV process system before you start creating pictures to be used in that environment. Alarm Banner window This desktop was designed specifically for use with DeltaV process systems.
It is made up of three windows: the Toolbar window, the Main window, and the Alarm Banner window. The Toolbar buttons provide single-click access to important pictures, directories, and other applications. Important Although it is possible to add, modify, or delete buttons from the Toolbar and make other changes to the operator desktop, it is recommended that you do not do any customization until you are thoroughly familiar with the purpose and function of all its elements.
The Alarm Banner at the bottom of the desktop also has important predefined functions. The five big buttons are used to notify the operator of the five highest priority alarms that have been activated. When an alarm is tripped, the name of the associated control module such as XV is displayed on one of the alarm buttons. The Alarm Banner also includes a node monitor button to let you monitor the current status of your controllers and workstations.
For modules created from library templates, Faceplate pictures are predefined. A little later you will learn more about the Alarm Banner and how to acknowledge alarms. The Main window is where the operator views a main picture, which is typically a process graphic that provides a view of the process or equipment.
A main picture is any picture created using the Main template. The Main template has some predefined features, such as a small toolbar with five buttons in the upper left corner. The template also contains some picture commands that are required by the DeltaV environment. Even in relatively small process systems, there are likely to be a number of main pictures.
Each main picture is created and saved as a picture file with its own unique name. Important The most important thing to remember about main pictures is that they must start from the predefined template named Main. Only subordinate pictures, such as pop-up messages to operators, should be created without using the Main template.
If you create a new picture file from scratch or use a different template as a basis, much of the DeltaV Operate environment will not work. Developing a Picture Hierarchy A process application normally has a number of linked pictures, such as plant overview, process monitoring, system status, alarm summary, and trend pictures.
There may also be pop-up windows for things like operator messages and help. Therefore, in addition to creating individual pictures, you will need to develop a system for linking pictures so that operators can easily get to the one they need.
Generally, the Overview is used as the top level in the hierarchy. You can add pushbuttons to the Overview that let you link to other pictures. You can even use a photograph or drawing with hotspots rather than pushbuttons that link your Overview to other pictures.
The design of your Overview picture is limited only by your imagination. Here is an example: Important The Overview picture has its own button on the Toolbar, so no matter how deep an operator gets into the hierarchy of pictures, it is always easy to get back to the Overview. This is one reason why you should put some thought into your Overview picture and how to make it useful for navigating to other important pictures. It is beyond the scope of this introductory manual to go into this in detail.
To learn more about the UserSettings file and global variables, refer to Books Online. The operator should not have more than one main picture open at a time. Here are some of the ways operators can move from one picture to another. The operator can easily jump to those pictures using the forward and back arrows in the upper left corner of a picture created with the Main template.
The button next to the Main field opens a History List. Simply click a picture in the list to go to that picture. The appearance of the DeltaV Operate window in run mode is dependent upon settings that you make in configure mode. There are security settings that allow you to secure the run-time environment and choose the specific actions that you want to restrict. For example, you can restrict the operator from closing the current picture and switching to another application.
Select the Enable Environment Protection checkbox and then select the options that you want to enable. Click the DeltaV User Settings button on the toolbar to access these settings. Experiment with these settings and refer to the online help and to Books Online for more information.
So, for now, when you switch to run mode, do not be concerned if your pictures do not look exactly like the images in this chapter. To ensure security in your plant, it is very important that you carefully develop your security scheme before making changes to the start environment. Refer to the online help and Books Online for more information before making changes to the User Preferences dialog. DeltaV Operate in configure mode opens with a blank drawing.
In addition to the menu bar and toolbars, the window is made up of a system tree and the work area. System tree Work area The system tree shows a hierarchical view of the files on the local node and all objects associated with each file. The system tree can be resized, moved, or hidden. Open a folder and double-click on a file to open the file in the work area. Notice how that object is highlighted on the picture in the work area.
Select File Close to close the file or click the right-mouse button and select Close. Continue to explore the system tree, and when you ready, continue to the next section. In the system tree, click the plus signs next to the Pictures folder to expand its contents, and then click the plus sign next to the Templates folder to expands its contents.
Double-click the Main template picture. The Main template and the Toolbox open in the Work Area. Notice how a plus sign appears next to the Main picture. Click the plus signs to see the objects that make up the Main template. The Main template has instructional text, including a description of the five buttons in the upper left corner. In your system, the background color may be gray rather than white, as shown in this document.
Later, we will tell you how to change picture background color, as well as object colors. Read the information on this template. Then delete the text by clicking in the center of the page, clicking the right mouse button, and selecting Delete or pressing the Delete key. Select File Save As. The Save As dialog box appears. Click the Up One Level button to go to the Pic folder. Be sure the picture is saved in the Pic folder.
Toolbars and the Toolbox Toolbars contain buttons that provide shortcuts to menu commands. Buttons that perform similar functions are grouped into separate toolbars. For example, the standard toolbar usually contains the Open, Close, Save, and Print buttons. Toolbars are owned by the WorkSpace or by Picture. The toolbar's owner defines when the toolbar appears. For instance, WorkSpace toolbars appear when the WorkSpace runs, Picture toolbars appear only when one or more pictures are displayed.
Note Picture toolbars are assigned to all pictures. You cannot assign toolbars to specific pictures. Click Workspace Toolbars. The Toolbars dialog box appears. By default the Workspace toolbars are displayed. Make sure that Show Screen Tips on toolbars in the lower left corner is selected. With Screen Tips enabled, when you pause the pointer over a tool in the Toolbox, its name will pop up.
Uncheck and recheck the various toolbars to see the buttons that belong to each toolbar. Watch the toolbar across the top of the window and see which buttons disappear and then reappear. Click the Customize button and use the online help to familiarize yourself with the Customize Toolbars dialog. Click the Help button for overall help on the dialog.
For help on individual fields in the dialog, click , then click on the field for which you want help. Later, when you are more familiar with the tools, you can add and remove buttons and toolbars to suit your needs. Click Close on the Customize Toolbar dialog box. Click Workspace Toolbars to reopen the Toolbars dialog and select Picture in the owner field.
It saves space on your picture because you do not have to keep several toolbars open. Click Close on the Toolbars dialog box. You can hide the Toolbox by selecting its title bar, clicking the right mouse button, and selecting Hide. You can move and resize the Toolbox and enable docking. Click the Toolbox title bar, hold the mouse button down, drag to a new location, and release the mouse button. Point to any corner or side of the Toolbox. The pointer changes to a two-sided arrow. Hold the mouse button down and drag to reshape the box.
Release the mouse button when the Toolbox is in the desired shape. Repeat the moving and resizing steps as needed to suit your personal preferences.
Click Picture and click the Customize button. Select Enable docking for selected toolbar and click Close. Disable or enable docking to suit your personal preferences. Color You can use color in two ways: 1. Adding foreground, background, or edge color to a selected object. Adding color to more than one object.
To add color to a selected object, select the object, click the right mouse button, choose Color, and then select Foreground, Background, or Edge. Once you select a color, click OK, and close the dialog box. To add color to multiple objects, select the Color button on the Toolbox.
The Color dialog box stays on your screen as you select colors. For the exercises in this book, we will use the first method. You select a color by clicking the color in the palette or selecting a color from the list. Default colors appear in the Shape Preferences tab of the User Preferences dialog box. To change the default colors, click Workspace User Preferences Shape Preferences, and then click the color box that you want to change Foreground, Background, or Edge and select the new default color from the palette.
Note Changes to the default colors do not change the colors of objects that are already in the picture. Tip To change the background color of the entire picture, click Edit Picture, click in the Background Color box, and a color palette appears from which you can select a background color.
Click OK to return to the picture and display the new background color. Line Styles and Fill Styles You can also change the default line styles, widths, and fill styles using a procedure similar to that for changing color defaults.
To change the default edge styles, width, and fill, click Workspace User Preferences Shape Preferences, and then edit the default item that you want to change. You may want to take a few minutes to experiment with drawing basic shapes and changing the foreground, background, and edge colors.
To get started, use the following procedure. Click the rectangle button on the Toolbox. Hold down the mouse button, drag the pointer to set the desired size, and release the mouse button to place a rectangle on the picture.
Select the rectangle, click the right mouse button and select Fill Style Cross Hatch. For the remaining steps, make sure the rectangle is selected.
Click the right mouse button, select Edge Style Dash Dot. Click the right mouse button, select Color Foreground and select yellow in the palette. Draw another rectangle. Note that none of the default colors, line style, or fill style have changed. Now you can add some basic shapes and text to your drawing using the rectangle, oval, line, polyline, polygon, and text tools.
Try coloring, moving, and resizing the objects. If you use the polyline or polygon tools, double-click to finish the object. When you have finished, click File Close and do not save the work you have done on the file. Links, Dynamic Properties, and Parameter References Links allow you to display real-time and system data in the DeltaV Operate application in run mode.
There are several different types of links. The links introduced in this tutorial are datalinks and trend links. In configure mode, properties are parameters of objects that you can alter using tools, menu commands, and dialog boxes. Dynamic properties are object parameters that change in DeltaV Operate run mode based primarily on changes in database values.
For example, a tank may change color as it fills, that is, as the current value of the level indicator changes. A parameter reference identifies the database field that supplies data to a link or dynamic property. The parameter reference syntax is node:tag. If the tag does not exist, you are asked if you want to use it anyway. To access the browser, click the ellipsis button next to the Source field to access the Browse dialog box. The first time the parameter browser is called, it may take a few seconds for the Browse dialog to appear.
Click the Datalink Stamper button in the Toolbox. The Datalink dialog box appears. To search for the parameter reference, click the ellipsis button. The Expression Builder dialog box appears. This may take a few seconds. The Up One Level button can be used to move up one level in the hierarchy. The contents of the selected level are displayed in the list box. A list of the modules assigned to the TANK area is displayed. Double-click the module name, LI A list of function blocks and module- level parameters is displayed.
Double-click the AI1 function block. A list of parameters is displayed for that function block. Double-click the PV parameter. A list of fields is displayed. Click the CV current value field, then click OK.
Or, simply double-click the CV field. DeltaV Operate assembles the node, tag, and field information and enters it into the Expression Builder dialog box. Click OK to return to the Datalink dialog box. Click OK in the Datalink dialog box. Note The DeltaV Operate application reads the datalink and automatically configures the settings in the Datalink dialog box based on the datalink. Click the mouse button in the upper left quadrant to place the datalink on the picture. The datalink appears on the picture as.
If you have not gone through the exercise of installing the module to a controller, you may get a message about the parameter reference not existing. After clicking the text tool the pointer remains in text mode. Click the mouse to change it back to an arrow pointer. Tip To move any object, you can select it and drag it to a new location. You can use the alignment tools to align objects horizontally and vertically. You can also use the arrow keys on the keyboard to make minor adjustments in the position of any selected object.
Click the Datalink Stamper button. This allows operators to change the value. Tip If you accidentally close the Datalink dialog box before completing your selections, double- click the link to reopen the dialog.
Place the datalink in the lower right quadrant of the screen. This datalink will be placed below the loop setpoint. Place the new datalink below the loop setpoint. This datalink will be placed below the loop process value. Select In-Place and click OK to let the application configure the fields in the dialog. Place the datalink below the loop process value. This datalink will be placed in the bottom left quadrant. If you browse for the parameter reference, the system will automatically supply.
Edit the parameter reference to have. In the Datalink dialog box, select None in the Type section and click OK to let the application configure the remaining fields in the dialog. Click the mouse to place the new datalink in the bottom left quadrant. Select the datalink and click the Data Entry Expert button on the Toolbox.
Click Pushbutton in the Entry Method section. By clicking on the datalink on the picture, the operator can start and stop the pump motor. Reposition the new datalink, if necessary, in the bottom left quadrant. Select File Close and save and close the picture. Note It is a good idea to save your picture file any time you do a significant amount of work on it. If you have a controller, the datalinks will show as numbers. If you have a placeholder for a controller, the numeric datalinks will show as question marks.
Return to configure mode by clicking the right mouse button and selecting Quick Edit. Either close the DeltaV Operate application by clicking the Close button in the upper right corner or continue with the next exercise. Dynamos As you develop a system of operator pictures, you may need to use an object such as a pipe, pump, or valve in more than one picture. You can save such custom built objects as reusable graphics called dynamos.
If you assign dynamic properties to an object, those properties are retained when you save it as a dynamo. In configure mode, DeltaV Operate provides prebuilt dynamo sets containing common process control objects, such as pumps, that you can paste into your pictures rather than drawing them yourself. You can modify an existing dynamo and save it in the original set or in a new set. You will likely want to save your most used dynamos in your own dynamo sets. To complete the Tank process picture, you will use several different dynamos and modify their dynamic properties.
Following is a brief summary of what you will do in the next few exercises. It will change from red to green to signal the pump going from off to on. The tank level will change to show the gradual discharge of its contents. The valves will change color to show their state closed or open. These could also be made to change color, but you will not assign dynamic properties in the example.
The picture will look something like the following figure. Use this as a guideline for placing objects on your picture. From the system tree in configure mode, expand the Dynamo Sets folder, and double click PumpsAnim.
The dynamo set opens at the bottom of your screen. Select PumpsAnimVertA1 and drag it onto the picture. Alternatively, you can drag the dynamo name from the system tree onto the picture.
Because this dynamo has animation properties, you are asked if you want to animate the pump color. We will animate the pump color so it changes from red to green when the pump goes from Stop to Start. Select the check box Animate Pump Color. The Color By dialog opens. Select Exact Match.
Click the Delete Row button and delete all but two rows. Set the value in the first row to 0. Set the value in the second row to 1. Click OK on both dialog boxes. The pump is placed on the picture. Creating a Tank Using a Dynamo Now you will add a tank that, in run mode, is supposed to show the level of the product in the tank by changing color. First, close the PumpsAnim dynamo set by selecting PumpsAnim in the system tree, clicking the right mouse button, and selecting Close.
Double-click the TanksAnim1 dynamo set in the system tree to open the dynamo set. Drag the tank labeled TankWDoorD1 to your picture, placing it a little above the motor, as in the figure shown earlier. On the Tank Dynamo dialog box, browse for the following tag for the tank level. Select Fetch Limits from Data Source. The tank is placed on the picture. Close the TanksAnim1 dynamo set. Finishing the Process Picture For other parts of the picture, use the dynamos in the following table and arrange them as shown in the earlier illustration of the process graphic.
Be sure to read the table footnotes for the block valve and regulatory valve. If you have forgotten how to animate the color for the regulatory valve, refer to the procedure for animating the pump on page Accept the defaults in the Valve Dynamo dialog box. Under the Color Threshold, select Range and set the colors as follows: is red; is green.
A pipe can be lengthened or widened by selecting the pipe, dragging one of its resizing handles, and releasing the mouse button. In fact, any of the graphic objects, including text, can be resized and reshaped by dragging the side or corner handles. The following procedure shows a suggested order for creating the objects. You can create them in any order you want. Add the vertical pipe to connect the tank and motor. Add an elbow pipe section to connect the motor to the horizontal pipe.
Move and resize objects as necessary. Add the block valve for XV according to the information in the table. Add a pipe to connect the pump and block valve. Add the regulatory valve for the control loop FIC Add two sections of pipe between the block valve and regulatory valve by copying and pasting or duplicating the existing section of horizontal pipe.
Click the right mouse button and use the context menu to select your editing choices. Using the Line tool, draw short vertical lines to indicate the orifice plate measuring the flow.
Rearrange your datalinks so that your picture now looks like the illustration shown earlier. Add text labels as shown. The links can use trend data from any floating point database field. You add charts by selecting the chart tool from the Toolbox. The chart tool gives you control over the layout, pen color definition, and so on. Click the Chart button on the Toolbox and move the cursor onto the picture.
The cursor turns into a cross-hair. Click the mouse and drag it to form a rectangle. Refer to the illustration of the process graphic to size the rectangle. Release the mouse button to place the chart on the picture. Select the chart and move it to the upper right corner of your working area. Select the chart, click the right mouse button, and select Chart Configuration.
Click the Chart tab, click in the Pen List area, and delete the sample pen displayed there. Click the Y-Axis tab and change the title to Flow. Enable the Apply to All Pens field. Click the X-Axis tab and change the title to Time. Take all other defaults or experiment with the settings and click OK. The chart is placed on the picture. Save the picture. You set the order by setting the Next and Previous Pictures in the Picture dialog box.
The operator can go forward and back through the defined sequence by clicking the arrow buttons that are standard in the Main template. The hierarchy for the tank process consists of a simple loop connecting the Overview and TANK pictures.
The pushbutton jump from the DeltaV opening picture to the Overview already exists. DeltaV Button Jump Next Next Overview Tank Previous In a more complex system, this horizontal loop might contain a series of tank pictures or perhaps a progression from a tank picture to a boiler picture to a reactor picture. You can have a number of these horizontal loops to define sequences of related pictures.
It is just a matter of determining the sequence you want and then setting the Next and Previous pictures. In addition, you can have jump-style links, such as pushbuttons, to replace the current picture with one that is not in the defined sequence.
Such links can be placed on your Overview picture or any other picture. Do not make any changes on this picture. Double-click the Next and Previous picture button. Open the TANK picture in configure mode if it is not already open. Double-click the Previous and Next Picture buttons in the top left corner of the Tank picture. For the Previous Picture, click the question mark button next to the Picture Name field. Save the picture by selecting File Save.
Creating a Pushbutton to Start the SFC After creating the control modules to monitor and control the equipment and flow loop, you created a Sequential Function Chart to automate the discharge process.
Now you need a way to enable the operator to start the SFC. There are a number of ways to do this. A simple method is to put a pushbutton on the TANK operator picture. On the Menu bar, click Insert Push Button. Click the Text tool on the Toolbox and type the text to appear on the button: Start Discharge. Resize the pushbutton to accommodate the text label. To do this, click the box and drag one of the handles.
Select the pushbutton and click the Task Wizard button on the Toolbar. The Task Wizard dialog box opens. Click the Perform Task button. The Write a Value Expert opens. Click Numeric and type 1 in the Value field. Click OK on the Task Wizard. Save TANK Close DeltaV Operate. Note Another way to assign the Start command to the pushbutton is to select the pushbutton, click the right mouse button, select Edit Script, and edit the Visual Basic script for the Pushbutton object.
A standard operator desktop and operating features make it easy to learn how to use this application. If you have installed the control modules to a controller, you will see numbers rather than question marks when you go to the TANK picture.
So, unfortunately, you will not be able to see the tank discharging its contents or get the full effect of working in an operator environment.
DeltaV Operate opens in run mode, displaying the DeltaV startup screen. Click Skip All to skip all remaining messages of this type. Click the small black question mark in the upper right corner. This displays a help system description of the buttons on the Toolbar.
Click the Close button in the upper right corner of the help window to close the help window. Click the small question mark in the lower right corner to see a description of the fields in the alarm banner at the bottom of the screen. Click the Close button in the upper right corner to close the help window. Click the DeltaV Utilities button on the Toolbar. Click the Books Online icon to open it. Click the Close button in the upper right corner of the Books Online to close that application.
Click the Overview button in the upper right corner to go to the Overview picture. Note If your links were not set up correctly, you can open the TANK picture by clicking on the Open button on the Toolbar and selecting that picture. Operators can go quickly to another picture by clicking on its name in the Main History list. Click the arrow next to the Main field.
This opens a list of the pictures recently visited. Click the pushpin button in the top left corner. Tip The pushpin button at the top of the Main History is a toggle switch for keeping the Main History open after a selection is made. The lock button locks the list, and the close button closes the Main History.
Click DeltaV. Click TANK to return to the process graphic. Lets the operator navigate from the current picture to the those defined as Previous and Next. Displays the Faceplate picture associated with the selected link. Displays the Detail picture associated with the selected link. Replaces the current main picture with the Primary Control picture for the selected link. Faceplate and Detail Pictures To open a Faceplate or Detail picture for a module using the standard button in the upper left corner of the Main window, the module must first be selected by clicking on one of its data links.
The Faceplate allows access to the most important operating parameters. The Detail picture provides access to almost all tuning parameters and diagnostic information. If the module does not have a selectable link, you can choose the module by clicking on the large Faceplate or Detail picture button in the main Toolbar. A dialog box opens in which you can enter the module name. The appropriate Faceplate or Detail picture pops up and the module name is added to the Module History list, which is similar to the Display History list.
This list lets you select, for any module listed, the Faceplate, Detail, or Primary Control picture. As with the Display History list, the Module History list can be pre-populated and locked using the UserSettings file.
Note that the data link in the upper right corner changes to display the currently selected link. Click the Faceplate button to call up the Faceplate for that module. At the bottom of the Faceplate, notice that the Detail picture button has a blinking line under it. Change the setpoint by moving the slider bar large white triangle to a new value. Tip The Trend button at the bottom of the Faceplate brings up the prebuilt module-specific trend picture for any module created from a DeltaV Library template.
Call up the Detail picture by clicking the Detail button on the Faceplate picture or the Main picture. Close the Detail picture. When you move your pointer over these fields, they are highlighted in a box.
To make a change, click in the field, type in a new value, and press Enter. Click the value for the data link for the loop setpoint. The value is highlighted.
Type a new value, such as 50, and press Return. Alarms have a descending priority of Critical, Warning, or Advisory and a status of acknowledged or unacknowledged. Unacknowledged alarms are more important than acknowledged alarms.
For alarms with equal priority and status, alarms with a more recent time stamp are more important than older alarms. If there are more than five alarms, the five most important alarms are displayed. Selecting the small button to the right of an alarm button displays additional information about the alarm in the line below the alarm buttons.
You can click an alarm button to go immediately to the screen identified as the Primary Control picture for that module. If there is an audible alarm, click the Silence Horn button to silence the alarm. This does not, however, acknowledge the alarm. In addition to the alarms displayed on the process graphics, a standard alarm list picture shows all active alarms and their priorities. Take a few minutes to get more acquainted with the application.
Change some data values, click buttons on the Faceplate pictures, call up the Help system and online books, and skim through the Books Online table of contents. When you are done, close DeltaV Operate. Continuous Process Data Collection The following subsections contain information on data collection in the DeltaV system. History Collection The history collection function defines the module or node parameters that are monitored and stored in the DeltaV Continuous Historian.
History collection is an integral part of a module. If you copy a module that has history collection, the new module includes the history collection.
This enables you to set up history collection for key parameters and copy the module for similar applications. You can add additional history collection to a library module. In Chapter 4, we set up history collection in Control Studio for the module that we created from scratch LI and acquired history collection for the other modules that we copied from the Library. The Continuous Historian subsystem monitors modules for history collection on an area basis and the Alarms and Events subsystem monitors for events and alarms on an area basis.
If you move a module from one area to another, history collection moves with the module. Explore Ebooks. Bestsellers Editors' Picks All Ebooks. Explore Audiobooks. Bestsellers Editors' Picks All audiobooks. Explore Magazines.
