The main topics covered in this chapter are: Introducing the setpoint program editor ( 1) Contents of this manual ( 2) 1 INTRODUCING THE SETPOINT PROGRAM EDITOR The setpoint program editor is a Windows 95/NT-based graphical programming tool that lets you create setpoint programs and recipes for the Eurotherm ICP (Industrial Control Package) setpoint programmer. It is part of the T550 LINtools suite of software for configuring LIN instruments. The editor also supports configuration of setpoint programs for the 2400 Series of controllers, communicating with these products via the Instrument Tools software. The editor outputs a complete setpoint program in compact binary format as a single.uys file, ready for direct downloading to the target ICP.

6 Chapter 3 THE SETPOINT FILE WINDOW Chapter 3 THE SETPOINT FILE WINDOW Chapters 1 and 2 introduced the setpoint program editor and told you how to install it in your PC. The present chapter aims to familiarise you with the editor's setpoint file window. This is where you create, configure, and view the setpoint files that will be downloaded to instruments for running as part of a control strategy. The creation and configuration of setpoint files is described in Chapter 4, Configuring a setpoint file, but you will need the information presented here to be able to benefit fully from that chapter. The main topics covered in this chapter are: Setpoint file window overview ( 1) The chart pane ( 2) The segment pane ( 3) The program pane ( 4) Highlighting objects in the setpoint file window ( 5) Operating on highlighted elements of the setpoint file ( 6) 1 SETPOINT FILE WINDOW OVERVIEW A setpoint file contains one or more programs that specify the values of a set of analogue and digital setpoints, over time. You create and edit setpoint files in the setpoint file window. An example window is shown in Figure 3-1. file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (1 of 16) [06/07/ :10:55]

7 Chapter 3 THE SETPOINT FILE WINDOW Figure 3-1 Main features of a setpoint file window (example) 1.1 The setpoint file window layout The window is normally divided into three resizeable panes --- the chart pane (see 2), the segment pane ( 3), and the program pane ( 4). Each pane presents an alternative view drawn from the same file data. You can alter the relative sizes of the panes ( 1.1.1), and highlight or emphasise various parts of the setpoint file in the different panes, to make the views clearer, or to edit the highlighted objects. Highlighting objects is described in 5, and editing setpoint files file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (2 of 16) [06/07/ :10:55]

8 Chapter 3 THE SETPOINT FILE WINDOW is described in Ch Changing pane sizes To change pane sizes within the file window, drag the pane borders as required. You can completely hide a pane in this way. To 'maximise' one of the three panes so that it occupies the whole setpoint file window, click the Program View, Chart View, or Segment View toolbar button as appropriate (see Figure 3-2). To restore the default 3-pane view, click the All Views button. Figure 3-2 'View' toolbar buttons 2 THE CHART PANE The chart pane displays a part of a setpoint program in graphical 'trend' format. In the example of Figure 3-1, two analogue setpoints ('Top Temp', 'Bottom Temp') and two digital setpoints ('Vent On', 'Blower On') are charted. Note that digital trends always appear at the bottom of the chart. The chart pane (and the segment pane) can be viewed in two ways --- segment based view and time based view. Figure 3-1 shows the segment based view. These views are explained in 3.4. NOTE. It is possible to prevent selected setpoint trends being displayed in the chart pane (Ch4 6.1 describes this). These 'hidden' trends, however, remain visible in the other panes. The numerical data in the chart pane can be exported as a text file in various formats (see 2.4). 2.1 Chart axes Value-axis Each Y-axis (value) gridline on the chart represents in this example 10 analogue setpoint units i.e. 100 units full scale. Individual analogue setpoints can be scaled differently on the same chart if required (see Ch4 6.1). To see a value scale for a particular trend, highlight the trend (as described in 5.1). For an analogue setpoint, a labelled scale appears at the right of the chart. For a digital setpoint, a labelled mark shows its position in the bottom portion of the chart. Figure 3-3 shows an example analogue setpoint scale. file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (3 of 16) [06/07/ :10:55]

9 Chapter 3 THE SETPOINT FILE WINDOW Figure 3-3 Chart pane scale (example) Time-axis The program on view in the chart (and segment) pane is subdivided along the X-axis (time) into individual segments, each running for its own specified duration and applying to all setpoints in the set. (You can see the segments more clearly in the segment pane below the chart --- see 3.) The time-axis can be displayed in two forms, to emphasise different aspects of the program. This is described in Line cursor & setpoint faceplates The vertical line cursor can be positioned by clicking the mouse cursor where required on the chart. Setpoint faceplates to the right of the chart display each setpoint value at the current line cursor position. In time based view (see 3.4.2), a time display shows the current cursor position along the time axis. For analogues, the setpoint faceplates show the configured display ranges as well (0-100 units by default). (Ch4 6.1 describes how to configure display ranges.) The line cursor is also repositioned when cells in other panes are clicked --- e.g. see 5.2. NOTE. Setpoint faceplates are not displayed for 'hidden' trends (see 2). 2.3 Time zoom control file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (4 of 16) [06/07/ :10:55]

10 Chapter 3 THE SETPOINT FILE WINDOW The time zoom control down the left of the chart lets you change the horizontal timescale of the charted trends, to see more or less of the viewed setpoint program in the chart area. Drag the control up or down to zoom the timescale in or out. Time zoom is mainly used in time based view. 2.4 Exporting chart pane data You can export the trend data visible in the chart pane in the form of tabular values in a text file. To do this: 1 Set up the chart pane to show the data to be exported. If you want only part of the chart exported, use the time zoom control ( 2.3) and the segment scroll buttons ( 3.1) to bring the required portion into view. Note that if you cannot fit exactly what you want in the chart, show more data than required, and edit the exported file afterwards. 2 Click anywhere in the chart pane to make it active. 3 Pull down the File menu and select Export to pop up the Export Table dialog (Figure 3-4). Figure 3-4 The Export Table dialog (example) 4 Configure the dialog fields according to how you want the exported text file to appear: Date/Time format. Select Text String to export dates in regular 'day/month/year', 'hours:minutes:seconds' format (e.g. 01/01/88 00:02:26 ). Select Spreadsheet Numeric Format to export dates in encoded spreadsheet format (e.g ). Separator. Select Tab or Comma as the separator to appear between columns in the exported text file. Sample interval. Select an interval from 1 second to 32 days. The interval determines the Number Of Samples exported, and their precise Time Range. Include Column Headers. Leave this box checked if you want the the column headings (i.e. Date/Time, and setpoint names) included in the exported file. 5 Finally, click the 'Copy To Clipboard' or 'Copy To File' button to export the file where required. file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (5 of 16) [06/07/ :10:55]

11 Chapter 3 THE SETPOINT FILE WINDOW Figure 3-5 shows part of an example exported file. Figure 3-5 Exported chart data (example) 3 THE SEGMENT PANE The segment pane displays an alternative view of the chart pane, in table format. Each table column represents a segment, and each table row represents a setpoint. There are in fact four possible segment types --- profile segments, call segments, end segments, and return segments --- which are described in detail in Ch Of these, only profile segments and call segments appear in the segment pane and the chart pane. The other segment types always have zero duration and appear only in the program pane. 3.1 Segment columns The columns representing the segments are headed by their segment names in the top row and their durations in the second row. Figure 3-6 shows four segments --- named 'Hold', 'Heat', 'Settle', and 'Call Prog 2 3 times'. Of these, the first three are profile segments and the last is a call segment. Segment columns line up exactly with the trends in the chart pane. If any segments are not visible in the chart and segment panes, clicking the segment scroll buttons scrolls these displays along by one segment in the selected direction. Figure 3-6 Segment pane (example) file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (6 of 16) [06/07/ :10:55]

12 Chapter 3 THE SETPOINT FILE WINDOW 3.2 Profile segments Each profile segment contains a set of profile commands, one for each setpoint being profiled. These commands determine how each individual setpoint value will change during that particular segment. The commands appear in the appropriate cells in the table. The rows in the table are colour-labelled with their setpoint names at the right of the segment pane (see Figure 3-6). Profile commands can cause a setpoint to adopt a particular value immediately, hold at its current value, or (for analogue setpoints) ramp linearly to a target value --- either at a specified rate or over the duration of the segment. Figure 3-6 shows examples of these commands, and Ch4 9 tells you how to configure them. 3.3 Call segments When a program is on display in the segment pane, a called program shows only as a single 'call' segment, even though the called program may in fact contain several segments. The name of the called program, number of iterations, and total duration (automatically calculated), are listed at the head of the call segment, but the remaining cells are blank. Figure 3-6 shows an example of this (in the fourth segment), headed 'Call Prog 2 3 times'. To view the missing details you must display the called program itself, by clicking any of its cells in the program pane ( 4.1), or via the Go To function ( 5.6). The selected program is displayed in the chart and segment panes, displacing the previous display. In the corresponding chart pane display, however, called program trends are displayed in full detail, 'seamlessly' integrated with the main (calling) program trends. In this way you can see the overall result of your setpoint program. 3.4 Segment based & time based views You can display the time axis in two formats to emphasise different aspects of the program --- segment based view, and time based view Segment based view Note that all segment columns are the same width in the segment based view shown in Figure 3-6, though their durations are unequal. In this view, the chart's time (X-axis) gridlines should be ignored Time based view Another way to display the time-axis is true-to-scale, with segment widths proportional to actual durations (Figure 3-7 shows an example). file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (7 of 16) [06/07/ :10:55]

13 Chapter 3 THE SETPOINT FILE WINDOW Figure 3-7 Example of time based view --- chart and segment panes This is the time based view, and the time gridlines adopt meaningful values based on the duration of the trends. The three time displays seen at the foot of the chart in time based view show the times (from program start) at the lefthand end of the chart, at the current line cursor position, and at the righthand end of the chart, respectively, in 'hh:mm:ss' format. You can select the most suitable view by clicking the appropriate toolbar button --- see Figure 3-8. Figure 3-8 Selecting segment based & time based views via the toolbar 4 THE PROGRAM PANE The program pane displays a tabular representation of the entire setpoint file, including all programs, and (for ICP file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (8 of 16) [06/07/ :10:55]

14 Chapter 3 THE SETPOINT FILE WINDOW targets) subprograms. It contains similar information to the segment pane, but lists the segments in rows instead of columns, and includes all program and subprogram names and associated 'call', 'end', 'return', and 'profile' segments. Figure 3-7 shows an example program pane containing these features. NOTE. All programs and subprograms in the program pane must operate on the same set of setpoints. Creating and configuring programs and subprograms is described in Ch4 3 and Ch Called programs A program can call (run) another program a specified number of times, provided the called program is listed below it in the program pane. So, a program cannot call itself, and in Figure 3-9, 'Prog 1' can call 'Prog 2', but not the other way round. Called programs can themselves call other programs subject to this rule. Figure 3-9 Program pane example 4.2 Customising the program pane As well as altering the size of the program pane --- by dragging its borders (see 1.1) --- you can also alter the width of each displayed column. To do this, click on the column border you want to move, and, holding the mouse button down, drag the border to the new position. You can also hide a column completely, if required, by reducing its width to zero. To restore a column width to its default value (24mm approx.), double-click on its righthand border. 5 HIGHLIGHTING OBJECTS IN THE SETPOINT FILE WINDOW Highlighting or selecting objects in the setpoint file window can simply make the views clearer, or can be a starting point for editing the selected objects --- e.g. using cut-&-paste ( 6). You can highlight a setpoint ( 5.1), a program file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (9 of 16) [06/07/ :10:55]

15 Chapter 3 THE SETPOINT FILE WINDOW segment ( 5.2), a profile command ( 5.3), or an entire program ( 5.4). You can also highlight selected groups of objects for multiple edits ( 5.5). In addition, the Go To function ( 5.6) lets you highlight any program, segment, or setpoint, selected from a menu of all available items in the file. You will see that the highlighting process, like other setpoint editor processes, works in an integrated way across all three panes in the window. NOTE. Highlighting usually involves clicking the mouse once on the selected object. Double -clicking most objects pops up a properties dialog, used to edit the object. Using a properties dialog is described in Ch Highlighting a setpoint trend When you highlight an individual setpoint trend in the chart pane, the colours of the other trends dim to focus your attention on the highlighted trend, and its scale and name appear along the righthand edge of the chart ( 2.1 describes the scale). There are several equivalent ways to highlight an individual setpoint trend, via the different editor panes: Chart pane. Click once on the trend's setpoint faceplate in the chart pane. Clicking a second time --- or selecting another trend --- de-highlights the trend. For clarity, the faceplates are colour co-ordinated with the corresponding trendlines (and with the setpoint labels in the segment pane). Note that the column representing the selected trend in the program pane also highlights (black), as does the corresponding row in the segment pane. The segment and program panes autoscroll if necessary to move the highlighted cells into view. Segment pane. Click on the trend's setpoint label in the segment pane. The whole setpoint row highlights, together with the corresponding program pane column. If you click on only one cell in the row, the corresponding trend still highlights but this time only the equivalent cells are highlighted in the segment and program panes. Program pane. Click on the column heading containing the required setpoint name, or on any cell in that column. The whole column or selected cell, respectively, highlights in the program and segment panes. 5.2 Highlighting a profile segment You can do this in several ways: Chart pane. Locate the line cursor in the required segment ( 2.2). The corresponding row and column of cells highlight in the program and segment panes, respectively. Figure 3-7 showed a highlighted segment. Note that if a setpoint is currently selected ( 5.1), the corresponding profile command highlights, rather than the whole segment. Segment pane. Click a segment name or duration cell to highlight the whole column. The line cursor moves to the start of the segment selected, and the corresponding row of cells highlights in the program pane. Program pane. Click a segment name or duration to highlight the whole row. The line cursor moves to the start of the segment selected, and the corresponding column of cells highlights in the segment pane. The chart shifts sideways if necessary to display the highlighted segment. file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (10 of 16) [06/07/ :10:55]

16 Chapter 3 THE SETPOINT FILE WINDOW 5.3 Highlighting a profile command To do this, click on the cell containing the profile command to highlight it. As usual, the corresponding cell in the other pane also highlights. In the chart pane, the setpoint trend containing the selected command also highlights, and the chart scrolls sideways if necessary to bring the selected command into view. The segment pane also scrolls sideways and vertically if necessary to screen the command. 5.4 Highlighting an entire program To do this, in the program pane, click on the cell containing the program name --- e.g. 'Prog 1' in Figure 3-9. All cells associated with the selected program highlight. The selected program is also displayed in the chart pane, and in the segment pane (with all its cells highlighted). 5.5 Highlighting selected groups of objects Highlighting groups of objects lets you carry out certain multiple edits on them (described in 6 and in Ch4). As well as highlighting the special blocks of cells already described above --- setpoints, segments, and programs --- you can also highlight any combination of these and other objects of your choice Highlighting adjacent cells To highlight a rectangular block of cells, click a cell at a corner of the rectangle, hold the mouse button down and drag the highlight to the opposite corner. Release the button. This works equally for a single vertical or horizontal line of cells. Figure 3-10 shows an example of a highlighted block of six cells, seen in both the program and segment panes. Figure 3-10 Block of adjacent cells highlighted Highlighting non-adjacent cells or blocks of cells To highlight isolated objects, highlight the first cell or cell block as described in 5.5.1, hold down the <Ctrl> key, then highlight the next cell or block. This adds to your selection. Continue in this way adding more objects to the file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (11 of 16) [06/07/ :10:55]

17 Chapter 3 THE SETPOINT FILE WINDOW selection as required. Finally, release the mouse button and <Ctrl> key. Figure 3-11 shows isolated objects highlighted. Figure 3-11 Isolated highlighted objects NOTE. You can switch mouse clicking between the program and segment panes during a multiple highlight operation. 5.6 Using 'Go To' to highlight an object The Go To function lets you highlight and display any of the available programs, segments, or setpoints in the current setpoint file, via a Go To dialog. To access the dialog, press the <Ctrl> + <G> keys, (or select Go To from the Edit dropdown menu). In the dialog (Figure 3-12), select the type of object required from the 'Go To What' list on the left, then select the particular item to go to from the resulting dropdown menu on the right. Finally, click the 'Go To' button or hit <Return> to highlight the selected item. Figure 3-12 Using the Go To dialog (example) NOTE. If a call segment is currently selected when you access the Go To dialog, the program called by the segment is automatically selected in the dialog menu. So in this case, just pressing <Ctrl> + <G> then <Return> highlights the called program immediately. file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (12 of 16) [06/07/ :10:56]

18 Chapter 3 THE SETPOINT FILE WINDOW 6 OPERATING ON HIGHLIGHTED ELEMENTS OF THE SETPOINT FILE You create and configure setpoint file data initially by entering values via properties dialogs. This is described in Ch4 4. But you can also manipulate the existing data in highlighted objects using the cut/copy/paste facilities ( 6.1) or 'drag & drop' ( 6.2). 6.1 Cut, copy, & paste Cut, copy, and paste are ways to rearrange existing setpoint file data without having to type or retype the data Cut The cut operation deletes the selected objects from the setpoint file, and copies them to the 'clipboard' (temporary PC memory area) for possible 'pasting' elsewhere (see 6.1.3). Any current clipboard contents is overwritten. You can cut single objects or mixed groups of objects multiple-selected from programs, setpoints, segments, and profile commands. NOTE. Exceptionally, cutting profile commands does not delete them but instead converts them to default settings. Defaulting profile commands is described in Ch To perform the cut operation, highlight the object(s) to be cut, then hit <Ctrl>+<X> --- or select Cut either in the Edit menu or in the context menu. (Highlighting objects is described in 5.) Copy The copy operation simply copies the selected objects to the clipboard, without deleting them from the setpoint file or altering it in any way. The selection of objects is the same as for cutting ( 6.1.1). To copy, highlight the object(s) and hit <Ctrl>+<C> --- or select Copy either in the Edit menu or in the context menu Paste The paste operation copies the clipboard contents to a specified position in the setpoint file window. The clipboard contents is left intact (and available for more pastes). For all pasted objects except profile commands, the paste operation adds to what is already present in the file, without overwriting any data. When you paste profile commands, however, you always overwrite existing commands. NOTE. If you try to paste objects into invalid or unsuitable positions, you are warned of this and the paste is either redirected (if possible) or completely aborted. Remember that you can undo a paste operation (and most other operations) with <Ctrl>+<Z>. file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (13 of 16) [06/07/ :10:56]

19 Chapter 3 THE SETPOINT FILE WINDOW How and where the pasted objects appear in the window depends on the types of object being pasted. Pasting programs. those already present. You can paste a single program or a group of programs into the program pane, to add to To do this, highlight any cell(s) in the program above which you want the pasted program(s) inserted, then hit <Ctrl>+<V> (or click Paste in the Edit menu or in the context menu). If you want the pasted program(s) to appear at the end of the list, then highlight a blank cell between programs before pasting. Pasting setpoints. present. You can paste single or groups of setpoints into the setpoint file, to add to those already To do this, highlight the setpoint before which you want the pasted setpoint(s) inserted, then hit <Ctrl>+<V>. If you want the pasted setpoint(s) to appear at the end of the list, deselect all setpoints before pasting. Pasting segments. You can paste single or groups of segments into the setpoint file, to add to those already present, in positions selected as for setpoints. Pasting profile commands. to overwrite existing commands. You can paste single or groups of profile commands stored in the clipboard, NOTE. When pasting a group of commands, it is advisable to limit your initial copy or cut selection to a rectangular or linear block of cells. Groups of non-adjacent cells paste down in a different shape from the original stored in the clipboard. (Selecting groups of objects is described in 5.5.) To paste a single profile command, simply highlight the cell you want to overwrite and hit <Ctrl>+<V>. NOTE. If you try to paste an analogue command over a digital command, the pasted data automatically converts to its digital equivalent if sensible. E.g. 'Set to ' pasted over a digital becomes 'ON'. Correspondingly, a digital 'ON' pasted over an analogue converts to 'Set to 1.000', and 'OFF' becomes 'Set to 0.000'. When a command cannot be validly converted (e.g. Ramp commands), the paste is aborted with a warning message. To paste a rectangular block of profile commands, you need only highlight the top-left cell in the target group of cells to be overwritten, before hitting <Ctrl>+<V>. If your specified (or implied) target area is not the same shape as the block being pasted, as many as possible of the cells in the clipboard are pasted into the available area, starting at the top-left cell, and any non-overlapping cells are ignored. (See also 6.2.1, step 3 NOTE.) 6.2 Drag & drop 'Drag & drop' operations are equivalent to cut/copy & paste operations ( 6.1), but are done entirely using the mouse and often far more easily. You can drag & drop all objects capable of being cut & pasted, with the same results and limitations Cutting & pasting objects using drag & drop file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (14 of 16) [06/07/ :10:56]

20 Chapter 3 THE SETPOINT FILE WINDOW To cut & paste single or groups of objects using the drag & drop method: 1 Highlight the required object(s). (Highlighting objects is described in 5.) 2 In the program or segment panes, locate the mouse cursor near any edge of the corresponding highlighted cell or block of cells. A small grey box appears on the cursor --- composite Figure 3-13 'A' shows this. Figure 3-13 'Drag & drop' operations --- moving a block of profile commands 3 Hold down the left mouse button and drag your selection to the target paste location. Release the button to effect the cut-&-paste in one operation. NOTE. Illegal locations cause a 'No entry' symbol --- see Figure 3-13 'B' --- to appear in place of the cursor. For profile commands, legal (but not necessarily valid) locations are flagged by a grey box framing the targetted cells, so you can see clearly where the overwriting will occur --- see Figure 3-13 'C'. Mismatches of shape between the dragged cell-group and the target area are shown up clearly by the shape adopted by the framing box. For other pasted objects --- programs, setpoints, and segments --- legal locations are flagged by a grey line showing where they will be inserted if 'dropped'. Figure 3-14 shows an example of this. file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (15 of 16) [06/07/ :10:56]

21 Chapter 3 THE SETPOINT FILE WINDOW Figure 3-14 'Drag & drop' operations --- copying a setpoint Copying & pasting objects using drag & drop To copy & paste objects, use the same procedure as for cut-&-paste ( 6.1.1) but hold down the <Ctrl> key before 'dropping' the selection into place. This causes a '+' sign to appear in the small cursor box, and your initial selection is not deleted. Figure 3-14 illustrates a copy-&-paste operation on a setpoint. Note the insert position indicated by the horizontal grey line between the 'Settle' and 'Stir' setpoints in 'Prog 2'. file:///g /ONLINEBK/DISK1/SPE/SPE_3/CH3.HTM (16 of 16) [06/07/ :10:56]

24 Chapter 4 CONFIGURING A SETPOINT FILE Chapter 4 CONFIGURING A SETPOINT FILE This chapter tells you how to access the setpoint program editor, create new setpoint files, and edit existing setpoint files. To get the most from this chapter you must be familiar with the features seen in a setpoint file window. This information is given in Chapter 3, The setpoint file window, which you should read first. The main topics covered in this chapter are: Accessing a setpoint file ( 1) Configuring a setpoint file ( 2) Adding programs & subprograms to the file ( 3) Configuring program & subprogram properties ( 4) Adding setpoints to the file ( 5) Configuring setpoint properties ( 6) Adding segments to a program ( 7) Configuring segment properties ( 8) Configuring profile command properties ( 9) 1 ACCESSING A SETPOINT FILE You create and configure setpoint files in a setpoint file window opened within the main setpoint program editor window. Setpoint files can be created or accessed directly from Windows Explorer ( 1.1), or from the setpoint program editor window ( 1.2). 1.1 Creating & accessing setpoint files from Windows Explorer You can create a new setpoint file ( 1.1.1) or access an existing one ( 1.1.2) Creating a new setpoint file from Windows Explorer To create a new setpoint file from Explorer (or on the desktop), first access the New menu --- by right-clicking or via the Explorer File dropdown menu. Then select Eurotherm Setpoint Program. A new program icon appears. Open up (double-click) the newly-created file. The editor window appears, containing a New SPE File dialog, shown in Figure 4-1. file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (1 of 24) [06/07/ :12:05]

25 Chapter 4 CONFIGURING A SETPOINT FILE Figure 4-1 Setpoint editor starting window --- 'New SPE File' dialog Use this dialog to select the required target type, and initial number of setpoints, programs, and segments. Your particular target selection determines what options and limits apply in the rest of the dialog. E.g. for a 2400 Series target, trying to specify more than 20 programs pops up a message telling you to 'Please enter an integer between 1 and 20'. Leave the target settings at their default values if you prefer to edit them later on. Click 'OK' to close the dialog and create the new file. Your specified setpoint file window opens in the main editor window, ready for configuring ( 2). Figure 4-2 shows the default ICP target file, which contains a single program called 'Prog 1 (New)' which in turn contains one segment, 'New Segment' and one analogue setpoint 'SP 1 (New)'. file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (2 of 24) [06/07/ :12:05]

26 Chapter 4 CONFIGURING A SETPOINT FILE Figure 4-2 New setpoint file window (ICP target default) Accessing an existing setpoint file from Windows Explorer To access an existing setpoint file from Explorer (or the desktop), simply double-click the file icon. The setpoint program editor launches, and the selected setpoint file opens up in the editor window, ready for editing as described in Creating & accessing setpoint files from the setpoint program editor You can create a new setpoint file ( 1.2.1) or access an existing one ( 1.2.2). file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (3 of 24) [06/07/ :12:05]

27 Chapter 4 CONFIGURING A SETPOINT FILE Creating a new setpoint file from the setpoint program editor First access the editor window from the Windows desktop by clicking 'Start', then 'Programs', then 'Eurotherm LINtools', and finally 'Setpoint Program Editor'. A blank editor window appears. To create a new setpoint file, click the New File button: A New SPE File dialog appears, shown in Figure 4-1, in which you select the target type, and initial number of setpoints, etc., as described in NOTE. If you locate the mouse cursor over a toolbar button, its function pops up as a brief 'tool tip', and a summary also shows in the status area at the foot of the window Accessing an existing setpoint file from the setpoint program editor window To work on an existing setpoint file, access the editor window as described in Then click the Open File button: and select a.uys file via the Open dialog. 2 CONFIGURING A SETPOINT FILE To configure your new setpoint file (or edit an existing one) you will need to know how to: add programs and subprograms to the file ( 3) configure program and subprogram properties ( 4) add setpoints to the file ( 5) configure setpoint properties ( 6) add segments to a program ( 7) configure segment properties ( 8) configure profile command properties ( 9) These configuration stages are described in the sections indicated. They can be done in any convenient order, and properties of objects can be changed at any time. file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (4 of 24) [06/07/ :12:05]

28 Chapter 4 CONFIGURING A SETPOINT FILE 3 ADDING PROGRAMS & SUBPROGRAMS TO THE FILE You can add more programs to a setpoint file, as required, subject to target and memory capacity. NOTE Series targets can support only 1, 4, or 20 programs according to how you have configured the No.of Programs field in the program properties dialog (see 4.4). In 2400 Series targets, all programs are of equivalent status, can be run independently, and finish with an 'End' segment (see 8.1). But note that 2400 Series programs can also be called by other 2400 Series programs, and so can act as subprograms In ICP targets, however, there is only one main program, which finishes with an 'End' segment. Every other program is a subprogram, callable from the main program and finishing with a 'Return' segment. (Configuring a program call is described in 7.4.) NOTE. Subprograms are not currently supported in ICP targets. You can add a new program (2400 Series targets) or a new subprogram (ICP targets) either at the end of the program pane list ( 3.1), or inserted where required ( 3.2). You can also delete existing programs ( 3.3). 3.1 Adding a program or subprogram to the end of the list To add a program or subprogram to the end of the current list of programs, highlight all current programs in the file (Ch3 5.5 describes highlighting all programs). Then click the Insert Program toolbar button at the top of the editor window: A new (highlighted) program appears at the end of the list, with a default name, e.g. 'Prog 12 (New)', ready to be configured ( 4). In ICP targets, the new program appears as a subprogram, finishing with a 'Return' segment. In 2400 Series targets the new program has a final 'End' segment, like all other programs in the list. 3.2 Inserting a program or subprogram into the list To do this, highlight the existing program above which the new program is to be inserted (Ch3 5.4 describes program highlighting). Then click the Insert Program button, as in Deleting programs and subprograms You can delete an existing program, or any group of programs, in a single operation. To do this, highlight the program(s) to be deleted, then press the PC's <Delete> key. Highlighting single and multiple objects is described in Ch3 5. You may also be able to delete an added program using the Edit /Undo command file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (5 of 24) [06/07/ :12:06]

29 Chapter 4 CONFIGURING A SETPOINT FILE (Ctrl+Z). NOTE. If you try to delete a called program when the segment calling it still exists (in a higher program), the editor warns you of this and the delete is denied. You must first delete the call segment (see 7.5). 4 CONFIGURING PROGRAM & SUBPROGRAM PROPERTIES The properties dialog. You configure many setpoint file properties --- including program properties --- via a properties dialog, which can be popped up by double-clicking the object to be configured. There are a number of different properties dialogs, each one specific to the object being configured. Figure 4-3 shows an example dialog for configuring programs. Figure 4-3 Program properties dialog --- Program page Properties dialog visibility. When a properties dialog has been accessed for a particular object, you can make it stay visible in the editor window, ready for future use with the same or other objects. Then, when you want to edit an object, clicking just once on the object converts the dialog into the appropriate one, saving access time. Click the 'Keep Visible' pushpin symbol at the top left of any properties dialog to toggle it between staying visible ('pinned' as in Figure 4-3) and closing after each use ('unpinned' as in Figure 4-4). Figure 4-4 'Keep Visible pushpin' --- 'unpinned' position shown To configure a program's properties, in the program pane, double-click the cell containing the name of the program or subprogram (or any cell in this row). For a program, this pops up the Program properties dialog, shown in Figure 4-3, for a 2400 Series target. For a subprogram, the Subprogram properties dialog appears instead (Figure 4-5). file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (6 of 24) [06/07/ :12:06]

30 Chapter 4 CONFIGURING A SETPOINT FILE Figure 4-5 Subprogram properties dialog --- Subprogram page The program properties dialog contains four or five pages, depending on target --- Program ( 4.1), Holdback ( 4.2), Default Units ( 4.3), File ( 4.4), and Command Types ( 4.5). The subprogram properties dialog contains three pages --- Subprogram ( 4.6), File, and Command Types. The File and Command Types pages are identical to those in the program dialog. You use these dialog pages to configure the required program or subprogram properties (or leave them at their default values). They are described in the sections indicated. 4.1 Program page The Program page (Figure 4-3) is seen only for programs, not subprograms. It contains five fields for configuring the program properties: Name. Type in a name for the program, overwriting the default one if required. Names can be up to 16 characters long (20 for full VGA variant targets). Use Dictionary. Check this box if you want users to be able to select the program name from a dictionary file, referenced by an index number (see next). (This field does not apply to 2400 Series instruments, and the box is 'greyed out'. ) Index. If the Use Dictionary box has been checked (see previous), entering a number in this field causes the Name field to be substituted at runtime by the entry in the dictionary file against this index number. In this way, the program name can be varied by changing either the dictionary file, or the index number, or both. (This field does not apply to 2400 Series instruments, and must be left at its default value. ) Cycles. This is the number (1-999) of times the program will run in 2400 Series instruments. Setting Cycles to '0' makes the program run continuously. (This field is ignored in ICP instruments, which run the program once.) 4.2 Holdback page file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (7 of 24) [06/07/ :12:06]

31 Chapter 4 CONFIGURING A SETPOINT FILE Figure 4-6 Program properties dialog --- Holdback page This page --- shown in Figure appears here only if you select the 2400 Series target type in the File page of the properties dialog (see 4.4). It contains a single field that lets you specify a holdback value applying to the whole program. (The action of Holdback is explained in 6.2. Please refer there for details.) NOTE. The holdback value specified here cannot be overridden elsewhere in the setpoint program file. For a 2400 Series target, you cannot specify a holdback mode that applies to the whole program, but you can specify individual holdback modes for each of its analogue profile commands. (This is described in 9.2.) ICP targets can also have holdback values specified, but these are configured for each setpoint ( 6.2), rather than for the whole program. 4.3 Default Units page Figure 4-7 Program properties dialog --- Default Units page for 2400 target The Default Units page (Figure 4-7) contains one or two fields, depending on target: Default Rate Time Units. Select a time unit from the dropdown menu, which will apply by default to all 'Ramp at Rate' profile commands in the program. file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (8 of 24) [06/07/ :12:06]

32 Chapter 4 CONFIGURING A SETPOINT FILE Default Storage Units. (Only for 2400 Series targets. Storage units are fixed at 'seconds' in ICP targets. ) Select the units for storing profile segment durations in the setpoint file. Note that if you subsequently specify a segment duration more precisely than the default storage units allow, the value may be truncated when the file is saved. E.g. with selected default storage units of minutes, a duration entered as '65 seconds' will be saved as '1 minute'. 4.4 File page Figure 4-8 Program properties dialog --- File page The File page (Figure 4-8) contains seven fields. Note that the selections available in some of these fields will be determined by what target you specify in the first field. Target Type. Select a target type from the dropdown menu. Note that if you select '2400', a fifth properties dialog page --- Holdback --- appears. Configuring holdback is described in 6.2. No.of Programs. (Only for 2400 Series targets.) Select a number from the dropdown menu (1, 4, or 20) to specify the maximum number of programs to be run. Startup Servo Mode. This field specifies whether the servo at startup sets to the value of the process variable PV, or to the setpoint value SP. Select an option from the dropdown menu. (Only for 2400 Series targets, where the selection applies to the single available setpoint. In ICP targets the selection can be made for individual setpoints --- see ) Power Fail Strategy. Select a strategy on power failure from the dropdown menu. Options available depend on the target instrument. (Only for 2400 Series targets. Refer to the target product literature for information on available power fail strategies. ) Event Outputs. Check the box if event outputs (i.e. digital setpoints) are to be enabled. (Only for 2400 Series instruments. The box is 'greyed out' for ICP targets, which do not need their digital outputs enabling.) file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (9 of 24) [06/07/ :12:06]

33 Chapter 4 CONFIGURING A SETPOINT FILE Synchronisation. Check the box to enable 'synchronisation' of the programs in several programmers. With this box checked, the eighth event output is used to effect this synchronisation. (Only for 2400 Series instruments. Refer to the target product literature for information on how synchronisation works. ) Authorised. (Only for ICP targets. ) Check the box if the setpoint program is authorised for use. Note that this box is simply an optional user-flag to indicate if the program is fully-configured and ready for use. 4.5 Command Types page Figure 4-9 Program properties dialog --- Command Types page The Command Types page (Figure 4-9) contains six profile command type fields plus checkboxes. Check those commands that you want enabled for use in the program segments --- by default all command types are enabled. Profile commands are explained in detail in Subprogram page The Subprogram page (Figure 4-5 in 4) contains three fields: Subprogram. Type in a name for the subprogram, overwriting the default one. The name must be unique within the setpoint file. Names can be up to 16 characters long (20 for full VGA variant targets). File. (See 4.4. ) Command Types. (See 4.5. ) 5 ADDING SETPOINTS TO THE FILE file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (10 of 24) [06/07/ :12:06]

34 Chapter 4 CONFIGURING A SETPOINT FILE By default a single analogue setpoint appears when you create a new file. You can add more setpoints, analogue and/or digital, to a file (target permitting), either at the end of the current list ( 5.1) or inserted where required ( 5.2). But note that analogue setpoints must always be in a group at the top of the list (in the segment pane), with digital setpoints grouped at the bottom of the list. The setpoint editor does not let you break this rule. You can also delete existing setpoints ( 5.3). NOTE. Every program and subprogram in a given setpoint file operates on the same set of setpoints. 5.1 Adding a setpoint to the end of the list To add a setpoint to the end of the current list of setpoints, first ensure that no setpoint is currently highlighted (Ch3 5.1 describes highlighting setpoints). Then click either the Insert Analogue Setpoint toolbar button at the top of the editor window: or the Insert Digital Setpoint button, as appropriate: A new (highlighted) setpoint appears at the end of the list, with a default name, e.g. 'SP 5 (New)', ready to be configured ( 6). NOTE. Another way to add a setpoint is to right-click the mouse anywhere on the editor window to pop up the editor's Context menu (shown in Figure 4-10). Point at the Insert item, and click Analogue Setpoint or Digital Setpoint in the popup. Alternatively, you can select Insert from the Edit dropdown menu at the top of the editor window. Figure 4-10 Adding a setpoint via the context menu If you try to insert an analogue setpoint into an existing group of digital setpoints, or add it at the end, you are file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (11 of 24) [06/07/ :12:06]

35 Chapter 4 CONFIGURING A SETPOINT FILE warned that the new analogue setpoint will be inserted before the first digital. You are also warned if the limit for the number of setpoints allowed in your target instrument has been reached. In this case the 'add setpoint' operation is aborted. NOTE Series targets can have only one analogue setpoint, and --- if Event Outputs have been enabled (see 4.4) digitals. ICP targets can have up to 16 analogues and 32 digitals. The Insert Analogue Setpoint and/or Insert Digital Setpoint toolbar buttons 'grey out' (de-activate) when a particular target can have no setpoint(s) added. 5.2 Inserting a setpoint into the list To do this, highlight the existing setpoint above which you want the new setpoint inserted. (Highlighting setpoints is described in Ch3 5.1). Click the Insert Analogue Setpoint or Insert Digital Setpoint button, as required, to insert the setpoint (as in 5.1). As before, if you try to insert a digital setpoint above an analogue setpoint, the editor warns you of this and diverts it to after the last analogue setpoint. Similarly, misdirected analogue setpoints are automatically diverted to before the first digital setpoint. 5.3 Deleting setpoints You can delete an existing setpoint, or any group of setpoints, in a single operation. To do this, highlight the setpoint(s) to be deleted, then press the PC's <Delete> key. Highlighting single and multiple objects is described in Ch3 5. You may also be able to delete an added setpoint using the Edit /Undo command (Ctrl+Z). 6 CONFIGURING SETPOINT PROPERTIES You configure a setpoint's properties using the Setpoint Properties dialog. To access this, double-click the setpoint faceplate in the chart pane, or the setpoint label in the segment pane, or the setpoint name (column heading) in the program pane. The dialog pops up as shown in Figure file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (12 of 24) [06/07/ :12:06]

36 Chapter 4 CONFIGURING A SETPOINT FILE Figure 4-11 Setpoint properties dialog --- Setpoint page This contains up to two pages --- Setpoint ( 6.1), and Holdback ( 6.2) --- depending on the target instrument configured for the file and the type of setpoint selected. Holdback does not apply to digital setpoints, and cannot be completely configured at setpoint level in 2400 Series instruments (see 4.2), so the second page is absent in these cases. 6.1 Setpoint page The Setpoint page (Figure 4-11) contains eight fields for configuring the selected setpoint's properties: Name. Type in a name for the setpoint, overwriting the default one if required. This is the name used to label the setpoint in the chart pane, and it also appears in the other editor panes. Names can be up to 16 characters long (20 for full VGA variant targets). Use Dictionary. Check this box if you want users to be able to select the setpoint name from a dictionary file, referenced by an index number (see next). (This field does not apply to 2400 Series instruments, and must be left at its default value. ) Index. If the Use Dictionary box has been checked (see previous), entering a number in this field causes the Name field to be substituted at runtime by the entry in the dictionary file against this index number. In this way, the setpoint name can be varied by changing either the dictionary file, or the index number, or both. (This field does not apply to 2400 Series instruments, and must be left at its default value. ) NOTE. Refer to Chapter 5 of the T2900 Multi-setpoint Programmer & Data Logger Customers' Manual, Part No. HA U005, for more information on using an index. file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (13 of 24) [06/07/ :12:06]

37 Chapter 4 CONFIGURING A SETPOINT FILE Hardware Reference. Type in the OPC address name for the corresponding process variable PV, without the device prefix. E.g. for an analogue setpoint, enter the tagname of the associated D25_RAMP function block. For a digital setpoint, enter the associated SPP_DIG function block bit --- e.g. SPP_DIG1.Out.Bit3. Display Range Low, Display Range High. Apply only to analogue setpoints. Enter the lowest and the highest values, respectively, that you want shown for this setpoint trend in the chart pane. These values also appear on the relevant setpoint faceplate. Colour. (The setpoint trace colour is allotted automatically and is not configurable.) Trended. Leave this box checked if you want to see the setpoint's trend in the chart pane. Unchecking the box removes the trend and its faceplate from the chart pane, but leaves it visible in the other editor panes. Note that this field has no effect on what is displayed in the target instrument when the file is downloaded. 6.2 Holdback page Figure 4-12 Setpoint properties dialog --- Holdback page This page (Figure 4-12) appears only for ICP targets, where holdback is configured for each setpoint. The values configured here apply to the setpoint in all segments. Holdback provides a way to extend the duration of a program segment to allow a measured process variable PV to 'catch up' with its setpoint SP, if it has deviated from it by more than a specified amount. Specifically, if at any time during the segment a PV differs from its SP by more than the specified Holdback Value, in a direction specified by Holdback Mode, then the program execution engine enters a hold state until the condition no longer applies. In this hold state, all SP ramps in the segment are 'frozen', so that they stay in step. The two fields in this page are: Holdback Value. Enter a value for the deviation threshold (delta value) beyond which holdback is triggered for this setpoint. file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (14 of 24) [06/07/ :12:06]

38 Chapter 4 CONFIGURING A SETPOINT FILE Holdback Mode. Select a mode from the dropdown menu: None disables the application of holdback in the program. Low triggers holdback when any PV is below its SP by more than the holdback value. High triggers holdback when any PV exceeds its SP by more than the holdback value. Band triggers holdback when any PV is in either the 'Low' or the 'High' condition. 7 ADDING SEGMENTS TO A PROGRAM This section describes the different types of segment seen in programs ( 7.1), how to add profile segments ( 7.2), insert profile segments ( 7.3), insert call segments ( 7.4), and delete segments ( 7.5). 7.1 Segment types There are four types of segment seen in the setpoint editor --- Profile segments ( 7.1.1), Call Program segments ( 7.1.2), End segments ( 7.1.3), and Return segments ( 7.1.4) --- which have different configuration fields that are target-dependent. (Figure 1-1 in Chapter 3 shows examples of these segments in the program pane of an ICP target configuration.) Profile segments These usually form the bulk of a setpoint program, and contain the profile commands that shape the setpoints. You can add profile segments as required to a program (see 7.2 & 7.3). They have six fields for configuration, which are the same for the ICP and 2400 Series targets. See 8.1 for more information Call Program segments You can insert call program segments as required into a program (see 7.4) in order to call (run) other programs in the file. Their durations are automatically calculated by the editor according to the duration of the called program and the number of iterations. They have two configurable fields that specify the called program name and number of iterations --- see End segments These segments have zero duration and are inserted automatically by the editor when you create a program. For an ICP target, the main (first) program listed in the program pane is terminated by an End segment, which has only one configurable field (end type) --- see 8.2. All subsequent subprograms are terminated by Return segments. For a 2400 Series target, every program is of equal status and so is terminated by an End segment, which has two configurable fields --- see 8.3. file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (15 of 24) [06/07/ :12:06]

39 Chapter 4 CONFIGURING A SETPOINT FILE Return segments These segments have zero duration and are inserted automatically by the editor at the end of any subprogram created in an ICP target (see 3.1). They are not configurable. Return segments do not occur in the 2400 Series target, which has no true subprograms. NOTE Series targets can have up to 17 segments, including the End segment. ICP targets can have up to 500 segments. 7.2 Adding a profile segment to the end of a program By default a single profile segment appears when you create a new program. You can add more segments to a program at any time (target permitting), either at the end of the current segments or inserted where required ( 7.3). To append a segment, highlight the program's 'End' segment in the program pane, or the whole program (by clicking its title cell). Then click the Insert Profile Segment toolbar button at the top of the editor window: The new segment appears at the end of the program, with a default name, e.g. 'Seg 12 (New)', duration, and profile command, ready to be configured ( 8). NOTE. Another way to add a segment is to right-click the 'End' segment (or program title cell) to access the context menu, then select Insert /Profile Segment. Alternatively, you can select Insert /Profile Segment from the Edit dropdown menu. 7.3 Inserting a profile segment into a program If you want to insert the segment at a particular place in the program, highlight the existing segment in front of which you want the new segment inserted. (Highlighting segments is described in Ch3 5.2). Then click the Insert Profile Segment toolbar button (or use the context or Edit menus as per the Note in 7.2). 7.4 Inserting a call segment into a program To insert a call segment at a particular place in the program, highlight the segment in front of which you want the call segment inserted. (Highlighting segments is described in Ch3 5.2). Then click the Insert Call Segment toolbar button (or use Insert /Call in the context or Edit menus as per the Note in 7.2). file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (16 of 24) [06/07/ :12:07]

40 Chapter 4 CONFIGURING A SETPOINT FILE NOTE. If you try to insert a call segment when there is no program available to be called (i.e. below the calling program in the program pane list), the editor warns you that 'The called program does not exist' and the insert is denied. You must first add a program below the calling program. 7.5 Deleting segments You can delete an existing segment, or any group of segments, in a single operation. To do this, highlight the segment(s) to be deleted, then press the PC's <Delete> key. Highlighting single and multiple objects is described in Ch3 5. You may also be able to delete an added segment using the Edit /Undo command (Ctrl+Z). 8 CONFIGURING SEGMENT PROPERTIES You configure segment properties via the segment properties dialog. If a properties dialog is currently visible (see NOTE in 6), simply click on the segment to be edited --- on a segment name/duration cell in the program or segment panes, or use the line cursor in the chart pane. Otherwise, access a new properties dialog by double-clicking on the segment. The configurable properties depend on the type of segment selected ( 7.1). The properties dialogs for these different segment types are described next, in separate sections. 8.1 Profile segment properties dialog The Profile segment properties dialog is shown in Figure file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (17 of 24) [06/07/ :12:07]

41 Chapter 4 CONFIGURING A SETPOINT FILE Figure 4-13 Its single Segment page contains six fields for configuration: Profile segment properties dialog Profile Name. Type in a name for the segment, which must be unique within the current program. Names can be up to 16 characters long (20 for full VGA variant targets). Use Dictionary. Check this box if you want users to be able to select the segment name from a dictionary file, referenced by an index number (see next). (Only for 2400 Series instruments. ) Index. If the Use Dictionary box has been checked (see previous), entering a number in this field causes the Profile Name field to be substituted at runtime by the entry in the dictionary file against this index number. In this way, the segment name can be varied by changing either the dictionary file, or the index number, or both. (Only for 2400 Series instruments. ) Duration (hh:mm:ss). Type in a duration for the segment, in the hh:mm:ss format. If the segment contains any Ramp at Rate profile commands, the field becomes read-only (greyed out) and automatically sets to the time required by the slowest Ramp at Rate profile command in the segment. NOTE. In 2400 Series targets, a segment containing a 'Set To' analogue command automatically adopts zero duration. Use Default. (Not used.) Storage Units. This read-only field shows the units used for storing profile segment durations in the setpoint file. (Selecting these units, and their possible truncation effect on segment duration values, is described in 4.3). 8.2 End segment properties dialog --- ICP target This dialog's single Segment page contains only one field for configuration: End Type. This lets you specify the state of the setpoints when the program finishes. Select Reset to reset all setpoints to their values prior to the start of program execution. Select Dwell to freeze the setpoints at their end-of-program values indefinitely. 8.3 End segment properties dialog Series target The End segment properties dialog for 2400 Series targets is shown in Figure file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (18 of 24) [06/07/ :12:07]

42 Chapter 4 CONFIGURING A SETPOINT FILE Figure 4-14 Its single Segment page contains two fields: End segment properties dialog Series target End Type. This lets you specify the state of the setpoints when the program finishes. Reset and Dwell work as for the ICP target, described in 8.2. Selecting Set Output causes the (single) analogue setpoint to adopt the output power level specified in the target instrument when program execution ends. (Refer to the relevant 2400 Series handbook for details of specifying this output power level.) Event Output Values. This 8-way field is enabled only if you have enabled Event Outputs for the program (see 4.4), and is disabled if 'End Type' is set to Reset. It lets you specify the states of each of the eight digital setpoints at the end of program execution. Click the 'On' or 'Off' radio buttons to select the required end states. 8.4 Call Program segment properties dialog This is shown in Figure Please refer to 3 for information on program calls and subprograms.

43 Chapter 4 CONFIGURING A SETPOINT FILE Its single Segment page contains two fields: Call Program. Use the dropdown list to select the name of the program to be called. Note that in 2400 Series targets this is the textual name, not the program number. Only those programs listed below the calling program in the program pane appear in this menu and are available for calling. Times. Enter the number of times the program is to be called (run). The limit is 999 iterations. 9 CONFIGURING PROFILE COMMAND PROPERTIES You configure profile command properties using the Profile Command Properties dialog. If a properties dialog is currently visible, simply click on the cell to be edited, in the program or segment panes. Otherwise, access a new properties dialog by double-clicking on the selected cell. The configurable properties depend on the type of the associated setpoint --- i.e. analogue or digital --- and also on the target. The command dialog contains up to four pages --- Command ( 9.1), Holdback ( 9.2), Segment and Setpoint ( 9.3). For digital setpoints, where holdback does not apply, the Holdback page is absent. NOTE. You can set profile commands to their default values, using the PC's <Delete> key. This is described in 9.4. You can also change selected commands to other command types using the Change to menu --- see Command page The fields in this page depend on the setpoint type --- analogue ( 9.1.1) or digital ( 9.1.2) Analogue setpoint commands Figure 4-16 Profile command properties dialog --- analogue setpoint Figure 4-16 shows the command page for analogue setpoints, which can contain up to three fields, depending file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (20 of 24) [06/07/ :12:07]

44 Chapter 4 CONFIGURING A SETPOINT FILE on the command type selected. All the fields are described. Select a command from the dropdown menu: Set To. Lets you specify a (new) value for the setpoint to adopt. This is a step-change in the setpoint. Enter the required value in the field, and press <Enter> to effect the change immediately. NOTE. In 2400 Series targets, a segment containing a 'Set To' analogue command automatically adopts zero duration. Dwell. Leaves the setpoint at its current value for the duration of the segment. Ramp To. Ramps the setpoint linearly from its current value to the specified target value, over the duration of the segment. The ramp rate sets automatically to achieve this change in the time available. Enter a target value in the field. Ramp at Rate. See Figure Ramps the setpoint linearly from its current value to the specified target value, at the specified rate. If the target is reached before the segment completes, the setpoint is 'dwelled' until the end of the segment. Enter the ramp rate in the per second field, and the target value in the to field. Figure 4-17 Profile command properties dialog --- Ramp at Rate fields NOTE 1. NOTE 2. A segment containing 'Ramp at rate' commands has its duration set automatically by the editor, and is read-only. The duration is calculated so as to let the 'slowest-to-target' setpoint just attain its target value. Any other setpoints in the segment already at target will 'dwell' while this happens. 'Ramp to' and 'Ramp at rate' commands cannot be mixed in the same segment. Servo To SP, Servo To PV. (ICP targets only. ) With ICP targets, in the first program segment only, it is possible to configure the servo to set to the setpoint value SP, or to the process variable value PV, at startup. This can be done individually for each setpoint. These two fields do not appear for other segments, or in other targets. (For 2400 Series targets this feature is configured globally --- see 4.4. ) Digital setpoint commands file:///g /ONLINEBK/DISK1/SPE/SPE_4/CH4.HTM (21 of 24) [06/07/ :12:07]

45 Chapter 4 CONFIGURING A SETPOINT FILE Figure 4-18 Profile command properties dialog --- digital setpoint Figure 4-18 shows the command page for digital setpoints, which can contain up to three fields, depending on the command type selected. Select a command from the dropdown menu: Set To. Lets you specify a (new) value for the setpoint to adopt. Click the On or Off radio button as required. Dwell. Leaves the setpoint at its current value for the duration of the segment. NOTE. In 2400 Series targets, 'Dwell' is not allowed for digital setpoints. Use 'Set To' instead. 9.2 Holdback page The action of Holdback is described in 6.2. Please refer there for details. Figure 4-19 shows the Holdback page, which is seen here only for analogue setpoints in 2400 Series targets. (ICP targets have their holdback configured at setpoint level --- see 6.2.)
