Issue Creating many TGML graphics that use the same or similar links and bindings can be difficult and time consuming. Environment TGML Vista Workstation Cause The copy and paste feature does not work on more than one link at a time. Resolution Whenever a Vista database export is performed on a group of TGML graphics, a .zip file is created that contains a source TGML file for each selected graphic, and one XML file describing all of the links and bindings contained in the database for those graphics. By editing this XML document and leveraging find/replace capabilities of text editors, the process of manually populating links and bindings can be sped up substantially. Warning: Always back up your database before performing any manipulation of XML files. There is a potential for your graphics to be ruined if a mistake is made, so be sure a current backup is available in this event. This is an advanced operation and should only be attempted by individuals with an understanding of Vista TGML graphics. This example shows how to populate the links on a standard menu that appears on every TGML graphic in a database. For simplicity, the database has three graphics: AHU1, AHU2, and AHU3. But the steps can be applied to hundreds of graphics just the same. A menu is created in TGML with a link to each graphic. The links are named AHU1, AHU2, and AHU3. These will correspond with the TGML objects in Vista that are also named AHU1, AHU2, and AHU3. The names do not have to match, but it is a good design standard to follow whenever possible. Right-click on the first graphic and choose Open Links Window. The first graphic should be populated manually to give a template for the rest. Populate each link using the traditional drag-and-drop. Verify the links are populated correctly. Go to File > Database > Export.... Select "Get a customized copy of the database.  This is the only option that needs to be selected. Highlight all of the graphics and drag them into the Export window. Click the green arrow in the upper-lefthand corner of the Export window and give the .zip file a name. Click Save. A message will appear stating "Vista Database Export completed" Find the resulting .zip file in the location specified in Step 4. Right-click and extract all files. Depending on the operating system and software, this step may vary. Unzip the specified file. In the resulting folder, find VistaDbImportExport.xml. Right click and open with Notepad or other text editor. Find Objects of type "TGML_LINK." If the RELREFID is populated, then this link has a destination. If it says RELREFID="" then this link is not yet populated. Time for some strategic find/replace. In this example, AHU1 has all of the links populated. But AHU2 does not. There are three links on each page that all share the same destination. Find the populated entry for AHU1 links: Object TYPE="TGML_LINK" NAME="AHU1.AHU1" DESCR="" SHCP="" SHCR="" IOLABEL="" RA="" WA="" KEYLABEL="" RELREFID="Graphics-AHU1" _PROTECTED="0" Find the non-populated entry for AHU1 links: Object TYPE="TGML_LINK" NAME="AHU2.AHU1" DESCR="" SHCP="" SHCR="" IOLABEL="" RA="" WA="" KEYLABEL="" RELREFID="" _PROTECTED="0"   Select everything after the graphic name that is not unique and perform a find replace: Find: AHU1" DESCR="" SHCP="" SHCR="" IOLABEL="" RA="" WA="" KEYLABEL="" RELREFID="" Replace: AHU1" DESCR="" SHCP="" SHCR="" IOLABEL="" RA="" WA="" KEYLABEL="" RELREFID="Graphics-AHU1"   Repeat this action for AHU2 and AHU3. When all of the edits have been made to the XML document, save and close it. Highlight the XML document as well as all of the TGML files in the unzipped folder. Right click and select Send to > Compressed (zipped) folder. This will create a modified database export file. In Workstation, go to File > Database > Import. Browse to the .zip file created in Step 12. De-select Perform alarm refresh and hit OK. A message will be displayed that says "Vista Database Import completed. All of the links on every page are now populated.

Issue How does the dynamic updates property work in TGML? Product Line TAC Vista Environment TAC Vista 5.1.7 TGML graphics. Cause A graphic can contain numerous bindings to values that you want to be able to display in the graphic. When there are numerous bindings, reading the values can be time-consuming and can slow down the performance of the graphic. By setting the DynamicUpdates attributes in the Bind elements of the graphic to either disabled or enabled, you can control which values are updated (which values the graphic subscribes to) when the graphic is opened. Resolution Created a Bind object in the TGML Graphic Editor Look at the Properties for the object. Under Behavior, the property DynamicUpdates is set to Enable by default. This can be set to Disabled and a Script can be added in an appropriate object which follows the following format: Example - activate a binding by clicking on a button function Click(evt){ button = evt.getTarget(); //Identify the target that has been clicked. parent = button.getParentNode(); //Find the parent node. binding = parent.getChildRecursive(""); //Identify the binding to be activated. binding.setAttribute("DynamicUpdates","Enable"); //Activate the DynamicUpdate property. } A simple example is attached. Click to download DynamicUpdate.zip.

Issue Where can additional information on the SPW100 series differential pressure switches be found. Environment SPW100, SPW102, SPW104,SPW106, SPW108, SPW110, SPW114 Cause Only the Schneider Electric datasheet and CE declaration are posted on the Extranet, no installation documents are available. Resolution Attached are the OEM suppliers datasheet and installation guide along with the Schneider Electric documents. Download here.

Issue When proportional 0-10Vdc type valve actuators are used with a SE8000 room controller, the actuators behavior is inconsistent. Environment SE8300 SE8350 SE8600 SE8600 Cause Some valve actuators e.g. wax filled (thermic type) have a high input impedance e.g. 100 Kohms. When connected to a SE8000 room controller, the actuators operation may be sluggish or may never operate. The SE8000 has a maximum output of 5mA when set to proportional control, using actuators with high impedance, the SE8000 room controller fails to recognise there is an actuator and does not drive it. Resolution A burden resistor can be fitted to draw some current from the SE8000 room controller because the actuator's impedance is too large. The burden resistor needs to be large enough not to affect normal use, but small enough to draw a current from the SE8000 room controller. Using ohms law: Valve actuator @ 100 Kohm SE8000 UO output is 5 mA, maximum Vdc output is 10 Vdc. Minimum size of burden resistor: 10 Vdc/5 mA = 2 Kohm. It may be necessary to increase the size of the burden resistor e.g. 10Kohm. The burden resistor is then installed between the signal ground and the signal, either at the controller or the actuator end. Test the actuators for correct operation.

Warning Potential for Data Loss: The steps detailed in the resolution of this article may result in a loss of critical data if not performed properly. Before beginning these steps, make sure all important data is backed up in the event of data loss. If you are unsure or unfamiliar with any complex steps detailed in this article, please contact Product Support Services for assistance. Issue Downloading new NXE or APB files using NL220 Product Line TAC Vista Environment NL220 Cause Downloading new or old firmware versions into application specific controllers. Resolution Before performing this update, make a backup of the NL220 project. In case something happens and the configuration parameters are lost, there will be something to reference. Go to extranet and download the latest NXE and APB files. In NL220, right click on the controller to be upgraded and go to Network > Upload configurations. This will update the database with the current configuration in the controller.   Next, right click on the controller again and go to Network > Replace. A box will open that is titled Commissioning a node. The option "Upload configuration from old node if present" should be checked. This will insure that the values in database are current with the controller. Under Configuration download, "Download all known database values" needs to be selected. This will download the configuration parameters back into the controller once the update is complete. Finally under Template, "Download a program to the node" should be checked. The file that was downloaded off of extranet earlier can now be browsed in. Note: The option ‘Keep current configuration on node’ is misleading. By selecting this option it will not download parameters to the node. So when you download the new APB file, the controller will retain the configuration parameters found in the APB file not what was originally on the node.   Click Continue

Issue How to set up a controller for Elevator Controls. Product Line EcoStruxure Access Expert Environment Win Server 2012 and above Cause Steps to configure Elevator Controls from the beginning. Resolution To achieve this the following steps need to be followed: Open Access Expert Click on the main controller (SSC) Add interface - MR16 Out Set the address of the interface (dip-switches 1-5 on the panel) Add Reader interface and name accordingly (Elv Flr 1) for example Select the Elevator Tab and make the appropriate selections Go to the Elevator Tab Associate the MR16 Out (Floor Relays) Set Floor Relays (1 through 16) Create an Elevator Access Level - this would be used for floors that have access to this level An Elevator Override Access Level can be created as well if an Unlock Schedule is required Create the Door Group and assign the necessary  reader or readers Go to General Configuration and select the System Settings Select the Hardware Tab On the Elevator settings, change the Elevator Relay  Time and Elevator Push Button times from 1 to 5 seconds Once configured, select the elevator reader, right click and choose the Pulse option to test the relays If correct, the assigned readers will Pulse Assign users to the Elevator individually or through the User List.   Note: Please keep in mind that if there are multiple readers for multiple floors, it is best that a reader be associated with its own MR16 Out, it is best practice as the relays cannot be shared between the readers. Meaning that if Reader 1 uses relays 1-8 the second reader would not be able to use 9-16 on that same MR 16 Out. It would need its own MR16 out for those floors. Note 2: When creating Elevators in Access Expert, the outputs used on the MR16Out should not be added as an Output once defined in the Reader. These are automatically assigned, if they are added then the Floor selections will not function properly. 

Issue How to set up a MicroNet Mi for use on a Xenta 555 Product Line Satchwell MicroNet Environment MicroNet Mi Xenta 555 Cause Installation instruction for setting up MicroNet Mi with Xenta 555. Resolution Updated June 2019 The MicroNet 50 series range MN350, 450, 550, 650 LCD and Touchscreen have been withdrawn from sale. The IAC 420, 600 and Touchscreen have now also been withdrawn from sale. No direct replacement is offered. Further information on these changes can be found in PA-00495 - Notice of Withdrawal - Satchwell Sigma and PA-00528 - End of Commercialization - Satchwell Sigma. ---------------------------------------------------------------------------------------------------------------------------------------------------------- Cold start the MN50-Mi-ARC or MN-MI-100 with ARCnet card (MN-Mi). Unplug any RS 232 cables that are connected to PL3 or PL4. Energise the MN-MI and verify that the RUN LED flashes at about once per second. Set all bit switches to off. Place bit switch 8 to the on position and then return to OFF position. Place bit switch 1 to the ON position. Place bit switch 8 in ON position and then return to OFF position. The RUN, WINK and MODEM LEDs remain lit for about 1.5 seconds, and then the RUN LED should flash at about once per second. Note: This is different from the cold-start procedure for a controller, which requires you simply to toggle switch 8. Plug the RS 232 cables to PL3 or PL4. Connect the Xenta 555.

Issue When attempting to add an Automation Server to an Enterprise Server, an error message "Log on temporarily disabled' is displayed. The operation fails and the Automation Server is not added to the ES. Error message displayed on version 1.8 Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Server Building Operation Workstation Building Operation Automation Server (AS, AS-P or AS-B) All of the above version 1.9 or earlier Cause This only occurs after an initial failed attempt to add a server to the Enterprise Server. On each subsequent attempt to add the server, it always tries to authorize to the server with the admin account's default credentials, which in most cases are no longer valid. This locks the admin account. So when the admin account has been locked initially, it will not be unlocked, as every time an attempt is made to add the server, the default admin credentials are being used, and therefore it fails. Normally a locked account is a temporary condition, but in this case it is never recovered. This problem occurs on version 1.9 or earlier. It was fixed in version 2.0. Resolution The current workaround to allow the SmartStruxure Server Device to be added to the Enterprise Server is to perform a Warm Start or by cycling the power on the device. Upgrade to version 2.0 or later to resolve the issue permanently.

Issue Background image is cut off when viewing TGML graphic Fit the image to the background, but it does not stretch to fit when viewing the graphic White bars on the side or top of live graphic Environment TGML Cause The TGML root object has a few attributes that default to: Background = #FFFFFF (white) Stretch = None Height = 600.0 Width = 800.0 These may not be appropriate for the graphic being created. Resolution In the TGML editor, navigate to the Objects pane. If the Object pane is not visible, go to View > Objects and make sure that is checked. Click on the root Tgml object.    Available properties are shown in the Properties pane below. If the Properties pane is not visible, go to View > Properties and make sure that is checked.   In a pure TGML graphic, the Background color will represent the color behind all of the components. If a large background jpg or bmp image is used, the Background color will represent the color that will show up as bars on the top and right of the graphic when it is not sized perfectly to fit in the viewer's window (if Stretch is set to None). Stretch will have three different options (this is also a user defined option, this attribute merely sets the default presentation): None -- The size of the graphic in the TGML editor is preserved in the viewer's window. This may result in blocks of color on the top or right of the graphic. It may also result in sections of the graphic being cut off from the view requiring the user to scroll to view. Uniform -- The graphic is stretched to fit the larger of either the height or width of the viewer's window. The aspect ratio of the graphic is preserved. This may result in blocks of color on the top or right of the graphic. Fill -- The graphic is stretched in both the horizontal and vertical direction to fill the entire screen. This may result in a stretched or skewed presentation of the graphic. Height and Width will set the height and width of the graphic when Stretch is set to None. In a pure TGML graphic with all vectored components, the height and width are merely relative to the size of the components and aren't of great concern. However, when a background jpg or bmp image is used, the height and width should be set to match the dimensions of the background image.

Warning Potential for Data Loss: The steps detailed in the resolution of this article may result in a loss of critical data if not performed properly. Before beginning these steps, make sure all important data is backed up in the event of data loss. If you are unsure or unfamiliar with any complex steps detailed in this article, please contact Product Support Services for assistance. Issue The size of ContinuumDB has reached or is near the 2Gb limit imposed by MSDE. The size of ContinuumDB has reached or is near the 4Gb limit imposed by SQL Express. Environment MSDE SQL Express Continuum Stand Alone. Cause The database is well over the SQL size limit (2Gb for MSDE, 4Gb for SQL Express) Since the database size has already exceeded SQL's limitations it is not possible to use the deletion query statement to truncate the log tables.  This is because SQL will attempt to guard against data loss during the deletion process by making a copy of the tables contents before deletion occurs. Before a single row has been deleted from the table the size of the database will actually grow larger, exacerbating the problem. Resolution You must delete the contents of each log table entirely (Alarm, event, error, log) using the TRUNCATE statement. This will delete the contents of these tables entirely without first storing them the data. Please note, you must... Make arrangements with the customer so that they can archive any log and event data they wish to retain. Backup the database before using the TRUNCATE TABLE command. Here is the syntax for the TRUNCATE statements TRUNCATE TABLE ContinuumDB.dbo.AlarmEvent TRUNCATE TABLE ContinuumDB.dbo.AccessEvent TRUNCATE TABLE ContinuumDB.dbo.ActivityEvent TRUNCATE TABLE ContinuumDB.dbo.ErrorEvent TRUNCATE TABLE ContinuumDB.dbo.ExtendedLog Once the table have been truncated, Right click on ContinuumDB and select Shrink > Database. Once the database size has been reduced, check the size and retest. Please note that once the database size has exceeded SQL's limit it is likely that the database has been damaged.  This process may or may not correct damage that has occurred to the database.
