Page 25: Devices Only
L-VIS User Manual LOYTEC  HTTP: This method uses web services to communicate with the device over a single port (usually port 80). The device must be running firmware 4.6.0 or newer. Since the same port and protocol is also used by the Web-UI, no additional setup in the firewalls of PCs or routers is necessary.
Page 26 3.2.2.2 CEA-709 (FT-10 / CEA-852) Connections In this mode, the communication channel is CEA-709 via a LOYTEC NIC such as a NIC- USB, NIC-PCI or NIC-852. The device must first be commissioned (assigned a network address), either by using the same network management tool as used for the other nodes in the network or by entering a suitable unused address in the CEA-709 setup menu.
Page 27  Only network interface hardware from LOYTEC can be used for this type of connection. Any LOYTEC NIC may be used to run the configuration software, that is, the software is not registered to specific network interface hardware.

Page 65: Configuration Software
The following sections describe the object tree and the LCD preview in more detail. 8.2 Object Tree The object tree shows all objects which are part of the L-Vis project. The top level contains three nodes. A root menu, a folder for objects which are not visible and not related to any of the menu items or pages below the root menu, and a folder to organize template pages which are then instantiated on pages below the root menu.
Page 66: Lcd Preview
L-VIS User Manual LOYTEC  Left click an object: The object is selected. All previously selected objects are deselected. If the selected object is a child object of a control, the page on which the control is located will be shown and the control will be marked in the LCD preview.
Page 67: Object Selection
L-VIS User Manual LOYTEC In many cases, there will be a number of different selectable objects at the same position, so one of them has to be picked as the primary selection candidate. This is done by the following rules: ...
Page 68: Selection Indicator
L-VIS User Manual LOYTEC  Click and hold the mouse button a short distance away from the objects you want to select.

It is therefore suggested to first upgrade the configuration software and then upgrade the devices. The firmware of the L-VIS device can be upgraded as newer firmware versions become available. To find the current firmware version of your device, use the Device Info… menu item in the View menu, which will be enabled when the software is connected to a device or go to the About Page on your device.
Page 75: Context Menus
Context menus are an important part of the workflow, since most operations related to the objects of the L-VIS project are accessible from the context menu of the object in question. The context menu is usually opened using a right mouse button click on the desired object in the tree view, but for objects visible in the LCD preview, the same context menu may also be opened by a right mouse button click on the preview of the desired object.
Page 76: Xml Export / Import
L-VIS User Manual LOYTEC If the copy is pasted into a different project, the referenced data sources may not be available at all. In this case, the required data sources are automatically created in the destination project, so that the references may be resolved. For example, it is possible to copy a page which operates on register data only, into a completely different project and the page will function the same way it did in the original project.

All data sources which are mentioned in the selected entries will be considered for renaming. If a particular source is actually renamed depends on the given naming rules, as described in the previous section.
Page 79: Find Instances
L-VIS User Manual LOYTEC 8.5.5.7 Remove Data Point This operation removes the selected data point objects from the project. It is useful to remove a number of data point objects in one step, instead of going through the object tree in the tree view and removing each data point individually.
Page 80: Add Pages From Data Points
L-VIS User Manual LOYTEC 8.5.11 Add Pages from Data Points Similar to the above command, but available for menu items. In this mode, the selected data point folder will be scanned for data points and pages will be created to visualize them. If there are sub folders present, a new sub menu will be created to hold the menu items for the data point sub folders, similar to the operation above (add items from data points).
Page 81: Images
L-VIS User Manual LOYTEC NOTE: It is important which of the controls you select first. The control which was selected first will act as the reference for the layout functions, as explained below. Once the controls were selected, execute the desired layout functions by pressing the buttons in the tool bar or using the commands from the Layout menu of the main window.
Page 82: Embedded Sources
L-VIS User Manual LOYTEC Below the image tiles is a group of buttons to manipulate the selected images or load new images.

Unsupported files are hidden, for example Visio, Corel-Draw, or Auto-CAD proprietary vector drawing files, which cannot be imported directly. Use the programs export function to save the image in SVG or PNG format for use in the L-Vis project. 8.8 Fonts Every device has a set of three basic fonts which cover the ISO-8859-1 (Latin-1) code set in three different sizes.
Page 85 (only containing the characters currently in use). This is useful for the small L-Vis devices, which use prebuilt and optimized versions of the fonts. Large devices usually read the original font source file, so the reduced size has no meaning in this case.

Big5, IBM, or Microsoft code pages (for example MS-CP1250). If such a font is loaded, it is automatically recoded to UCS-2 before it is used, since the L-VIS device itself does not recognize encodings other than UCS-2. The font recoding is done using the coding tables found in the directory Encodings, located in the program directory.

L-VIS User Manual LOYTEC projects with recurring graphical elements, like room automation, the effort for creating the project is considerably reduced. References to data points used by the template can be variable, such that each instance can automatically work on a different set of data without any extra work to re-route the data point references manually.
Page 89: Improved Structure
L-VIS User Manual LOYTEC 8.10.5 Improved Structure As shown in the above section, the use of templates can greatly enhance the structure and therefore maintainability of a project. It guarantees that the project follows certain standards, no matter who is building the top level project based on the templates from a ready-made library.

L-VIS User Manual LOYTEC specified here, otherwise the user will see the control but will not be able to select it and input new data. Simple controls like text, numbers, bitmaps, and vector controls can also be rotated and flipped in X and Y direction using the options on this page. Note that this will affect the entire control.
Page 95 L-VIS User Manual LOYTEC NOTE: If the device firmware is older than 4.2.0, all color settings done on this page will be limited to the 256 color VGA palette, even for RGB capable devices. Starting with firmware 4.2.0 on RGB devices, colors can be selected from a new RGB color selection dialog which also includes an input field to set the transparency of the color.
Page 96: Object Description
9 Object Description 9.1 Introduction Every L-VIS project is built using a number of different objects. Each of the objects has a relatively simple function. To build a complex project, the simple objects are put together and organized in an object tree, which is shown in the tree view of the configuration software.
Page 97: Menu
L-VIS User Manual LOYTEC 9.2 Menu A menu object is used to manage a collection of menu item objects. On the device, a menu is a window which opens on the left side of the display and shows the items which are contained in the menu.
Page 98: Menu Item Properties
L-VIS User Manual LOYTEC Each item object can hold zero or more page objects and zero or one menu object, as shown in the object hierarchy diagram. It depends on the connected objects, what will happen when the user selects the menu item.
Page 99: Page Properties
L-VIS User Manual LOYTEC 9.4 Page Page objects are simple objects to organize the control elements which are visible on the device. When a page object is connected to a menu item and the item is selected from the menu, the page and all the controls on it will be shown on the display. Previously visible controls will be hidden, but will continue to exist on the device (so that a trend control may continue to record data, for example).
Page 100: Controls
L-VIS User Manual LOYTEC 9.5 Controls All objects which can be displayed on a page are called controls. This is because they are usually used to provide to user with an interface to control a data point value or trigger actions.
Page 101: Bitmap Control
L-VIS User Manual LOYTEC  URL: If the contents have the form of a URL, like http://www.host.com, the specified URL will be followed and displayed in a browser window of the size and position given by the text control. ...
Page 102: Numeric Control
L-VIS User Manual LOYTEC controls. Push button mode is activated on the Text / Bitmap / Drawing property page using the Enable Push Button Mode check box. Once enabled, the mode of operation is selected on the right via three radio buttons. The options are: ...
Page 103 L-VIS User Manual LOYTEC  Value Range: The values entered in these two fields (min –max) define the limits for input of new values. The user cannot input any value below min or above max. Values received from input data points are always displayed, even if they are outside the allowed input value range.
Page 104 L-VIS User Manual LOYTEC  Percent: The given value is interpreted as a factor and shown in percent. The value itself will normally be between 0 (0%) and 1 (100%), but other values are of course possible and displayed accordingly (1.5 = 150%, -0.3 = -30%).
Page 105 L-VIS User Manual LOYTEC  Specify significant digits: This option toggles between definition of integer and fractional digits, and definition of the range of significant digits. Defining a minimum number of desired integer digits and a fixed number of fractional digits leads to an output where the decimal point is always at the same location.
Page 106: Bar Control
L-VIS User Manual LOYTEC  Left Justified: This option causes padding characters to be inserted to the right of the converted number, so that the number appears left justified within the specified field width. The option has no effect if the field width is equal to or smaller than the space occupied by the converted value.
Page 107 L-VIS User Manual LOYTEC  Frame: The actual bar which displays the current value has a one pixel wide frame around it.  Bar: Inside the frame is the bar which actually shows the current value. With increasing values, the bar moves up or to the right.
Page 108 L-VIS User Manual LOYTEC NOTE: Set the desired value range, before you determine size and position of the bar, especially if tick marks and/or a scale will be drawn. This is important since the scale which best fits the current size will be determined and drawn as you resize the control. Depending on the value range, the space requirement of the scale and the optimum size of the bar will vary.
Page 109: Trend Control
L-VIS User Manual LOYTEC going up and down. If you switch color assignments, you can use the moving bar to selectively uncover parts of the background. Example 2: In front of the above window showing the moving sunblind, a completely transparent bar control may be placed (both bar color and container color are set to the transparent background and drawing of the bar can be disabled using the ‘Invisible Bar’...
Page 110 L-VIS User Manual LOYTEC 9.5.6.1 Internal Trends Whenever a normal data point is connected to the trend control, the control itself will record the data received from the data point and store it in the file system when the option Preserve Data is set.
Page 111 L-VIS User Manual LOYTEC Color Name Element to which the color applies Labels Numbers of the value scale and the time scale. Horizontal Grid Horizontal grid lines (if the grid is enabled). Vertical Grid Vertical primary grid lines (if the grid is enabled).
Page 112 L-VIS User Manual LOYTEC  Scale Labels: Enables drawing of scale labels. Note that scale labels should always be enabled for controls which have the Y-Scaling option set. On the right side, the Time Axis is configured. Note that some of these options only apply for data points trended locally by the control while other options apply also for display of external trend data.
Page 113 L-VIS User Manual LOYTEC At the bottom left of the property page, it is possible to set options regarding the individual data points connected to the control. Select the desired data point first to activate these options. For the Mode setting, the following options are possible: ...
Page 114 L-VIS User Manual LOYTEC the tick mark spacing is compatible to the spacing on the primary axis and matches the position of the horizontal grid lines. NOTE: Even if the preserve data flag is set, a trend control may still discard the stored data when it reboots.
Page 115 L-VIS User Manual LOYTEC NOTE: Assign good names to your trend control objects, to make it easy to identify the data files and relate them to the trends which are visible on the device. Consider to add the name of each trend to the page where the trend is shown, so that the user is able to clearly identify each control and its data file.
Page 116: Date Control
L-VIS User Manual LOYTEC NOTE: The values shown in the cursor box are always the most recent known values at the cursor position as recorded in the trend log. Changing the interpolation mode changes the way the trend curve is drawn, based on the available data records, but it does not change the values displayed in the cursor box.
Page 117 L-VIS User Manual LOYTEC A font for text mode can be selected on the Common Properties page. All other settings can be done on the Date/Time Control property page. The basic configuration is done in the Options section. The first option is a style selector, offering the following styles: ...
Page 118 L-VIS User Manual LOYTEC data point updates are only used to synchronize the time displayed on the control with the time received from the data point and do not have any direct influence on the controls update rate. The last option is actually related to the selected date pattern in a locale aware control and is discussed in the appropriate section below.
Page 119 L-VIS User Manual LOYTEC 9.5.7.2 Available Pattern Fields On the left side of the property page is the list of available date pattern fields to choose from. Since some of these fields are only available for the auto formatter and others only for raw date patterns, set the desired mode first before adding fields to the pattern.
Page 120 L-VIS User Manual LOYTEC  Day of Week in Month: Day of week in month (numeric), indicates the n occurrence of the current weekday in the current month, as in 2 Wednesday in July, or 3 Monday in December. Pattern symbol F.
Page 121 L-VIS User Manual LOYTEC When used in conjunction with a year number, make sure to use Year in “Week of Year” instead of the standard calendar year. Pattern symbol w.  Cyclic Year Name: Calendars such as the Chinese lunar calendar (and related calendars) and the Hindu calendars use 60-year cycles of year names.
Page 122: Data Log Control
L-VIS User Manual LOYTEC Use the buttons next to the field with selector to add and remove fields and move the selected field to a different position in the list. Note that the field position is not relevant when the auto-formatter is used, as the list only specifies which date components the formatted output should contain.
Page 123: Schedule Control
Please see section 7.2.1 for details about operating a schedule control in standard mode on the running L-VIS device. 9.5.9.2 Extended Mode In extended mode, the control provides a calendar and event based view of the schedule data.
Page 124 In this mode, it is therefore possible to use the smallest built-in font to save space on the screen and enable the user to see as much information as possible, especially on the smaller L-Vis devices. 9.5.9.4 Schedule Control Properties The properties to set on the Schedule Control property page define the basic appearance of the control and control access to various operations which modify configuration data.
Page 125 L-VIS User Manual LOYTEC be enough space and the effective period must either be disabled or shown on a separate line.  Enable extended user interface: This option is available if the device firmware is 4.2.0 or newer and there is only one data point connected to the control.
Page 126 L-VIS User Manual LOYTEC from (weekly/low/normal/high). The mapping is optimized to work together with schedules generated by LWEB-900, which also uses distinct priority levels for the entered events. Even in a standalone system, it may make sense to use this option to make the UI easier to read for users which are not familiar with the numerical priority scheme of the underlying network technology.
Page 127 L-VIS User Manual LOYTEC When the option ‘Use event colors for value’ is enabled, the three available event colors are assigned to the available value presets in a round robin fashion. The first value will use event color 1, the second value will use event color 2, and the third value is drawn in event color 3.
Page 128: Alarm-List Control
L-VIS User Manual LOYTEC  Change effective period: This operation allows the user to change the effective period of the schedule, thereby enabling and disabling not only single days but the entire scheduler unit.  Edit day patterns of exception days: This operation allows write access to the contents of the calendar which is connected to the scheduler unit.
Page 129 L-VIS User Manual LOYTEC  US date format: This option selects the US date format, which uses the order month, day, and year, separated by slashes (MM/DD/YYYY).  Read only (no ACK buttons): This option, when checked, instructs the control never to show ACK buttons.
Page 130: Vector Drawing Control
L-VIS User Manual LOYTEC NOTE: If an action object is connected to the alarm list control and the action trigger is set to ‘value update’, the action will be executed whenever a new entry is added to the alarm list.
Page 131 L-VIS User Manual LOYTEC  Filled: Available for rectangles, circles, and polygon drawings, defines that the object should be filled with the color specified as the container color, rather than the background color. To draw a frame only, leave this option unchecked and make sure the transparent background option on the Color property page is checked.
Page 132: Analog Meter
L-VIS User Manual LOYTEC While in drawing mode, the control occupies the entire screen. New lines or points may therefore be drawn anywhere on the page. Start and end points of lines or line segments are indicated by small squares, to make it easier to find and operate on these control points.
Page 133 L-VIS User Manual LOYTEC On the Common Properties page, a font may be selected to be used for the scale labels. Similar to other controls, color configuration is done on the Color property page. The following colors are supported by analog meter controls:...
Page 134: Knob Control
L-VIS User Manual LOYTEC  Needle Cover Size: Diameter of the small round cap covering the needle base. Can be set to 0 to disable the needle cover.  Tick Length: Length of the tick marks in pixel. Can be set to 0 to disable tick marks (same as disabling the tick mark option in the basic setup).
Page 135: Basic Configuration
L-VIS User Manual LOYTEC and labels is transparent. This way, the backlight can illuminate ticks, labels, as well as any other cut-outs.  Rotating Knob: On top of the faceplate, the rotating knob is drawn. There are various ways to draw the knob, ranging from none at all (already part of the faceplate image), a knob image, or a predefined knob available in different styles like brushed metal or a plastic-like knob with selectable color.
Page 136 L-VIS User Manual LOYTEC  A control with a fully opaque knob, with no LED cut-outs inside the knob may have the knob background color unset, as it will never be visible.  In conjunction with the indented style, choosing a half transparent mid-grey as the indicator fill color creates an overlay effect, where the software drawn indicator blends nicely with the underlying knob image.
Page 137 L-VIS User Manual LOYTEC  Show Labels: Draw labels onto the faceplate. Turn off when using a faceplate image which already contains labels or when no labels are desired. Note that if the label area of a faceplate image should be usable for input, a font of similar size than the one used on the faceplate image must be selected, such that the control can determine the outer boundary of the labels on the faceplate image.
Page 138 L-VIS User Manual LOYTEC  Static: A fixed band ranging from range start to range end.  Band Left: Backlight from range start, up to the current knob position.  Band Middle: Backlight from Midpoint to the current knob position.
Page 139 L-VIS User Manual LOYTEC 9.5.13.6 LEDs This line defines cut-outs for the backlight which can be added to the faceplate, such that the backlight can shine through them. This option can be used with the software drawn faceplate as well as image faceplates, in case they do not provide the necessary cut-outs.
Page 140: Webcam Control
L-VIS User Manual LOYTEC 9.5.13.8 Input There is currently one option affecting the way the knob behaves during data input:  Input by knob rotation only: This option prevents the knob from aligning its position with the touch point when input mode is entered (see also Section 7.2.1 about knob control data input).
Page 141 URL. Even though the LWEB client can usually detect the media type automatically, playback will start faster if the media type is already known. For L-Vis devices, this option has no effect. Media type is always detected automatically without any additional delay.
Page 142 L-VIS User Manual LOYTEC  [user:password] : Credentials used for authentication. If specified, a character separates the credentials from the camera address.  <address>: IP address or DNS name of the camera.  [/path] : Additional path component, used to specify the type of video stream to access.
Page 143: Data Point
L-VIS User Manual LOYTEC playback started, or the connection attempt resulted in an error which is shown in the control. This will ensure that the output data points will accurately reflect what the user currently sees on the display. NOTE: Using run time control is optional.
Page 144: Data Point Properties
It is important to understand this concept to understand what can be configured on the Data Point property page of L-Vis data point objects. The key is that there can and usually will be multiple data point objects in the L-Vis object tree, referencing the same data point in the data point configuration.
Page 145 L-VIS User Manual LOYTEC NOTE: The value translation of a data point can be very useful to modify a value on its way between a data processing object and a register or network value. Using this facility, simple data manipulation like the inversion of a state or the addition or subtraction of a fixed offset can be archived without using a separate math object.
Page 146 L-VIS User Manual LOYTEC  Reverse Direction: This option inverts the data direction of the data point object to be the opposite of the referenced data point, for example, the value of an output NV may be used as input for a math object or a trigger or may be trended by a trend log control.
Page 147: System Startup
L-VIS User Manual LOYTEC  MinSend: At least the specified amount of time has to pass between two successive update messages on the network. If the device delivers mode updates than this, intermediate values will not be sent out, until the minimum send time has passed, at which time the current (most recent) value is sent out.
Page 148: Data Point Icons
L-VIS User Manual LOYTEC NOTE: The system startup update flag can be controlled separately for input and output direction, but it cannot be enabled or disabled individually for each data point reference in the project. Also note that making a data point persistent may cause an initial value update with the stored value after system boot up, regardless of the system startup update flag.
Page 149: Mapping Table Properties
L-VIS User Manual LOYTEC A mapping table can include text, bitmaps and colors at the same time. If connected to a text control, the text part will be shown together with the color settings. When the same mapping object is connected to a bitmap control, the bitmap will be shown. Number and bar controls use the color setting only.
Page 150: Color Mapping
L-VIS User Manual LOYTEC Entry button to calculate a color gradient from the color of the first entry in the selected range up to the color of the last entry in the selected range. NOTE: The gradient function will operate on the alpha channel in the same way as for the normal color value, so that on devices which support ARGB color mode, this function can be used to generate gradients from opaque to transparent.
Page 151: Action Objects
L-VIS User Manual LOYTEC 9.9 Action Objects Action objects are used to execute various actions on special occasions. As such, they are often connected to controls, to trigger an action when the user touches, releases, or selects a control. In some cases, they are connected to data point connector objects, to watch incoming data point values and trigger an action when a certain value is received.
Page 152 L-VIS User Manual LOYTEC  Sound buzzer: Output a tone on the internal buzzer. The frequency and duration of the tone can be adjusted in the Options section. Useful to create audible alarms when a data point or register reaches a certain value.
Page 153 L-VIS User Manual LOYTEC NOTE: The action update data points can also be used to increment or decrement the value of a register or of a network output / feedback input pair, which is required to implement up/down buttons to dim light or modify a temperature set point. To do this, connect the register read point (or the network feedback point) as well as the register write point (or network output point) to the action.
Page 154 L-VIS User Manual LOYTEC NOTE: The trigger of touch and release actions while moving the touch position around between controls (without releasing the touch screen) is consistent with the display of the selection frame. Moving from one control to another without releasing the touch screen will cause the selection frame to follow the movement, always marking the control which is currently touched.
Page 155 L-VIS User Manual LOYTEC  While touched: The action is executed as long as the parent object is being touched. As above, observe that this condition must be satisfied at the time the action trigger fires, or the action will not be executed. In practice, this means that the condition ‘while touched’...
Page 156: Page Links
L-VIS User Manual LOYTEC Autoplace: The popup is placed near the button which triggered the action, but not overlapping the button if possible. Auto-Close: To use with any of the placement options, causes the popup to be closed automatically after the user did not touch the screen for the amount of time after which popups should be closed automatically (including popup menus).

Page 158: Collection Properties
L-VIS User Manual LOYTEC to function together on the same page. This way, the page continues to work when it is copied or moved to another project, because the required invisible objects are copied together with the page. The base collection outside of the main menu should only hold objects which are related to the device, rather than specific page functionality.
Page 159: Alarm Generators
Boolean value may be translated into any two values, one to signal ‘alarm clear’ and one for ‘alarm set’. This is most useful if the generated alarm is to be processed further or displayed on the L-VIS device, for example to trigger actions or display warning messages.
Page 160: Alarm Generator Properties
L-VIS User Manual LOYTEC 9.11.1 Alarm Generator Properties Once all inputs and the output are connected, the alarm generator may be configured on the Alarm Generator property page. For each of the connected inputs, an independent set of parameters is required. The available input points are listed in the top left area of the property page.
Page 161 L-VIS User Manual LOYTEC turn it back on until the device significantly cooled down, to avoid constant ON/OFF cycles. Such an application can be done by connecting the temperature data point two times. To distinguish between them, append SET to the name of the first data point and CLEAR to the name of the second data point (on the General property page).
Page 162: Data Point Connectors
L-VIS User Manual LOYTEC 0.5 would be a good value. For the Action, select Set on Alarm Enter and select the desired output value for a cleared alarm from the dropdown list named Value for Alarm Set Action. This is because we actually define an alarm condition when the button is pressed. As a result of this alarm condition, we then reset the ‘real’...
Page 163: Math Object Properties
L-VIS User Manual LOYTEC NOTE: Math objects are often used as standalone objects, reading from the connected inputs and writing the result back to a connected output. Such math objects are organized in folders, either below the global object folder or within a folder located on a page. However, math objects can also be used in place of input data points.

Depending on the Options on the right side, the control starts to blink at a slow or fast speed.
Page 168: Templates
L-VIS User Manual LOYTEC  Updates resulting in a condition CHANGE: This mode fires the trigger every time the result of the trigger condition changes, from TRUE to FALSE or vice versa. Subsequent updates which lead to the same result do not repeatedly fire the trigger, as opposed to the above modes.
Page 169: Instantiating A Template
L-VIS User Manual LOYTEC data points. The way to make this possible is to distinguish between fixed data points which will be the same for every instance of the template, and variable data points which will be replaced by different data points for every instance.
Page 170: Changes To Data Point Folders
L-VIS User Manual LOYTEC instance object. This can also be used to switch a template instance from one template to another.  To create instances of multiple templates in one step, place the related templates in a template folder, drag the entire folder, and drop it on the page where the instances should be created.
Page 171: Nested Templates
L-VIS User Manual LOYTEC Starting with version 6.1 of the configuration software, these situations are handled automatically to avoid broken templates and instances. Renaming a data point folder will automatically adjust all affected base paths to use the new name, such that the change has no negative effect on existing templates and instances.
Page 172: Nested Base Paths
L-VIS User Manual LOYTEC A $ sign, followed by the number of the base path of the parent template which was chosen as the basis for the relative path ($1 to $4), followed by the actual path (in parenthesis) which is currently set at this location. Since a template may have up to four different base paths, it is necessary to know to which one of them the sub template path is relative.
Page 173: Nested Changes
L-VIS User Manual LOYTEC there are a few other things which may need to be modified, for example colors or text for headlines. While many aspects of the instance will be controlled by the referenced data points and the actually used data points will vary from instance to instance, it is not always feasible to control everything just via data points.
Page 174: Base Path Placeholder Tags
L-VIS User Manual LOYTEC  Now the text color is changed to blue in the instance of A. This change is stored together with the instance of A, so the pen symbol now also appears on the tree icon of instance A.
Page 175 L-VIS User Manual LOYTEC tags are not supported in mapping table entries. The placeholder must appear directly in the text field of the text control.  Show Page Action: The show page action, when used with a relative path to the target page, accepts placeholder tags in the path string.
Page 176: Data Point Configuration
Working with data points is the same for the entire line of LOYTEC products. This chapter explains the use of the data point system on which L-Vis projects are built. 10.1 Data Points 10.1.1 Overview Data points are part of the fundamental device concept to model process data.
Page 177: Timing Parameters
L-VIS User Manual LOYTEC  Binary: A binary data point contains a Boolean value. Meta-data for binary data points includes human-readable labels for the Boolean states (i.e., active and inactive texts).  Multi-state: A multi-state data point represents a discrete set of states. The associated data type is a signed integer machine variable.
Page 178: Persistency
L-VIS User Manual LOYTEC 10.1.4 Persistency Data point values are by default not persistent. This means that their value is lost after a power-on reset. There exist different strategies for initializing data points with an appropriate value after the device has started.
Page 179: Custom Scaling
LOYTEC NOTE: A notification received by the L-Vis application from a data point may trigger execution of actions or commands like visibility or color changes, or it may result in a recalculation of a formula and cause a new notification about the changed result to be sent.
Page 180: Structures
L-VIS User Manual LOYTEC choose to generate one data point of direction value instead of two separate data points. This data point can be read and written, so the desired direction will have to be specified at each place the data point is used, whereas it is implicitly known with separate data points.
Page 181 L-VIS User Manual LOYTEC The following properties are available as property relations:  feedbackValue: This property relation is used for feedback alarm conditions. The data point value is compared against the feedback value. An alarm is generated, if these values differ (by a certain amount). It exists only, if an alarm condition has been created.
Page 182: Engineering Units
L-VIS User Manual LOYTEC 10.1.11 Engineering Units Analog data points have an engineering unit property that defines the physical unit of the underlying scalar value. The engineering unit is displayed to the user as a human-readable text which can be selected from a drop down list of available units. Once a valid engineering unit was selected, a green checkmark appears .
Page 183: Multi-Slot Connections
L-VIS User Manual LOYTEC  Binary/Multi-state to Analog: The Boolean or state value is directly converted to an analog value (e.g. state ID ‘4’ is written as ‘4.0’) as a default. The user should specify an adapter to map the Boolean or state value to designated analog values.
Page 184: Global Connections
L-VIS User Manual LOYTEC has a slot for each input and output, which can be connected to the respective data points as depicted in Figure 5 (b). For this multi-slot connection the math block adapter defines a fixed layout of the slots; no more slots can be added to this connection.
Page 185: Ast Features
L-VIS User Manual LOYTEC How a global connection is created and configured is described in Section 10.8.5. Note that the number of configurable global connections on a device is limited (see Section 15.10). 10.3 AST Features 10.3.1 Alarming The alarming architecture comprises a number of entities. Objects that monitor values of data points and generate alarms depending on an alarm condition are called alarm sources.
Page 186: Scheduling
L-VIS User Manual LOYTEC Alarmed data points also possess other property relations. The ‘enableAlarm’ property relation can be used to disable or enable alarm conditions when linked to a data point. The property relations ‘highLimit’, ‘lowLimit’, ‘deadband’ can be used to modify analog alarm conditions.
Page 187 L-VIS User Manual LOYTEC  Daily: This event occurs every day, starting at a given date and ending at a given date.  Weekly: This event occurs every week on the specified weekday.  Monthly: This event occurs every month following a date range or a defined rule (e.g.
Page 188: Trending
L-VIS User Manual LOYTEC  A date range: This defines a range. Starting with a start date and ending with the end date. No wildcards should be used.  A Week-and-Day definition: This defines dates based on a week, such as every 1st Friday in a month, every Monday, every last Wednesday of a month.
Page 189: E-Mail
L-VIS User Manual LOYTEC 10.3.4 E-mail The e-mail function can be combined with the other AST features. The format of an e-mail is defined through e-mail templates. An e-mail template defines the recipients, the e-mail text, value parameters inserted into the text and triggers, which invoke the transmission of an e-mail.

For calculating the difference between the current value and any historic value, the filter definition can be configured to delta mode. This is a shortcut to creating a math object processing the historic filter data point and the underlying data point.
Page 191: Schedulers
L-VIS User Manual LOYTEC Based on the NV the data point is derived from, the following kinds of data points are created:  Simple NVs that hold only one scalar value, e.g., SNVT_amp: Those kinds on NVs are represented as analog data points. The data points holds the current value, NV scaling factors are applied.
Page 192: Dynamic Polling In Cea-709
L-VIS User Manual LOYTEC 10.4.5 Dynamic Polling in CEA-709 External input NVs in CEA-709 rely on polling. Static polling can be configured by setting the poll cycle (see Section 10.1.2). In addition, this technology also supports dynamic polling. When dynamic polling is enabled, polling is only active for those NVs for which an external OPC client, the current page displayed on the LCD screen, or the current page displayed on the web interface requires a refresh.
Page 193: Bacnet Schedulers
L-VIS User Manual LOYTEC The direction of BACnet server objects deserves a closer look. The direction specified for data points in the configuration software always refers to the network view of the communication. The definition of input and output objects in BACnet, however, refers to the process view, which is opposite to the network.
Page 194: Bacnet Trend Logs
L-VIS User Manual LOYTEC underlying BACnet objects are enabled. Alarm conditions can be specified for analog input, output, value objects (AI, AO, AV), for binary input, value objects (BI, BV), and for multi- state input, value objects (MSI, MSV).
