Issue When many trend logs are linked to the same time object for emailing via a Receiver Group, some of the trend logs may not be sent. Environment Xenta Server Xenta 511, 527, 555, 701, 711, 721, 731, 913 Cause The Xenta Server cannot send more than approx. 50-60 simultaneous emails before some are lost.  The limit appears to be dependent on the size of attached trend logs and the number of addresses in the Receiver Group list. Resolution For a single email address, split the trend logs into groups of no more than 40.  Link the logs in each group to a different time object and stagger the times at which they are sent.  If the Receiver Group definition contains multiple email addresses, reduce the number of trend logs in each group accordingly.

Issue Prior to XBuilder 5.1.1, it was not possible to change the type of an Xenta Server in an XBuilder project once it had been created.  Sometimes there is a need to move the project to a different type of Xenta Server without losing all the links and bindings within the project. Environment Xenta Server XBuilder 5.1.0 or earlier Xenta 511, 527, 555, 701, 711, 721, 731, 913 Cause In XBuilder 5.1.0 or earlier, it is not possible to edit the Xenta Server type in the network pane of the XBuilder project Resolution Upgrading to Vista/XBuilder 5.1.1 or later will allow you to easily change the device type directly from XBuilder.  Note that this must be done from an XBuilder project that is saved to the computer. If the project is in a Vista database start by opening the XBuilder project, clicking on File > Save as and then save it to the computer. Then, close XBuilder, reopen XBuilder and open up the saved copy of the XBuilder project from the PC. In the XBuilder Project menu select 'Change Target type...'.  Choose your preferred target device from the drop-down list.   If it is not possible to upgrade, the following instructions allow an XBuilder project to be transferred to a different type of Xenta Server without losing graphic bindings or bindings between objects on the System pane and the Network pane.  The one proviso is that the target Xenta Server's hardware must be able to support any network defined in the source project and have the same or better Menta and User graphic capabilities.   There are many different combinations of Server types and BMS platforms that these instructions could apply to in general.   The example given here transfers an Xenta 555 project to an Xenta 731.  The Xenta 555 has a Lonworks network and a Modbus network and is part of a Vista database.   Creating the Xenta 731 in the Vista database: Open the Vista database containing the Xenta 555 project. Right-click on the 555 and select Edit from the dropdown menu. The XBuilder project opens.  Keep this open for the following steps. In the Vista database create a new Xenta 731.  The name is not important but it should be similar but not identical to the 555 it will replace. Transferring the Lonworks network to the Xenta 731: In Vista, drag and drop the LON network from the 555 to the 731. Right-click on the 731 and select Edit from the dropdown menu. The 731 project opens in a new instance of XBuilder.  Rename the default folder in the system pane to the same name as the top level folder in the 555 project. In the 731 project right-click on the LON object in the Network pane.  Select 'Refresh network from TAC Vista'. Transferring the Modbus network to the Xenta 731: In the 555 project, right-click a Modbus device and select 'Edit Device template' When the device editor opens, select File | Save as.. Save the file in the default location with the default name. Repeat steps 2 to 3 for all Modbus devices in the network. In the 731 project recreate the Modbus network using the templates just saved.     Transferring the System objects to the Xenta 731: In the 555 project, right-click an object below the top level folder and select 'Copy'. Move focus to the 731 project, right-click on the top level folder and select 'Paste'. Repeat steps 1 and 2 for each object and folder below the top level in the 555 project.  Selecting a folder also selects all the objects and folders beneath it.  Although it is possible to copy the top level folder in the 555 project, it is not possible to paste it into the 731 project. Graphics bindings are retained and the reference paths are automatically updated with the new network tree i.e. 'TAC_Xenta_555' is replaced with 'TAC_Xenta_731'. Some object bindings will be broken e.g. Time objects.  These must be rebound manually. When all objects have been copied across and rebound if necessary, close the 555 project. Deleting the Xenta 555 and downloading the project to the Xenta 731: In the Vista database, delete the Xenta 555. Generate the 731 project.  There will be a warning message offering to copy the original TGML files to the new default location.  Select 'Yes'. The 731 project should now generate without errors. Download the project to the Xenta 731.   If the 555 only contains a Modbus network, a similar methodology will also work with standalone 555 and 731 projects.

Issue How to estimate the thermal load (BTU/hr) that your controllers and equipment will produce. Environment All electrical equipment. Cause Need to know what the thermal load of our equipment will be for calculating air conditioning capacity. Not all of our equipment has this information provided in data sheets. Resolution It is possible to calculate the thermal load based on the power consumption of each device. See here for an online calculator. You can calculate the BTU/hr using the following formula. BTU/hr = Power (W) * 3.1412141633 As an example, looking at the Continuum AC-1 I/O module's datasheet, we see that it consumes 2.6W without the attached reader (you would need to add the power from the reader as well if it is being powered by the AC-1). Which gives us; AC-1 = 2.6W * 3.412141633 = 8.87 BTU/hr Use this same calculation for any other devices that you require the thermal load for.

Issue The SMS Nokia mobile phone simulator does not function in RAM 2.0 and Win7 Environment Windows 7 RAM Sigma Vista Micronet Cause When using the Windows 7 and in RAM 2.0, SMS alarm messages can be tested by using the SMS test interface. The Nokia dummy phone does not appear on the Windows desktop when a message is sent. Resolution Interactive Services Detection needs to be enabled: Goto Windows Start menu, type services.msc. In the Services window, scroll down to Interactive Services Detection and set to either "Auto" or "Manual" and start the service. In RAM allow a message to be sent to the dummy SMS phone. An icon will appear in the task bar, click on "View the message", the dummy SMS phone is now seen with the message sent to it.

Issue User has a backup of my files that they have restored onto a new workstation PC but now they are unable to edit the files.  For example: A Continuum graphic needs to be edited and cannot save changes but can save as a new graphic. Environment Window OS Windows XP Windows 7 8 8.1 10 Windows Vista Cause This is caused by Microsoft Windows OS. Windows will automatically make a file "Read only" if it has been moved from another PC  Resolution The solution is to change the files back to read / write. Example: Open Windows Explorer and find the folder you want to change, for this example it is "Continuum graphics." Right click on the folder and select properties, which shows a tab that will be ticked next to "read only" deselect this tab and then select apply. Once windows has finished changing the folder and its contents to read/write the user will be able to go into continuum and edit graphics.

Issue Not all features are seen when a BMS platform is viewed using remote control software e.g. RealVNC Environment Remote Control Software. Cause Not all features are seen when a BMS platform is viewed using remote control software. One example is: When the SmartStruxure License Software application is used, the drop down menu for adding the license detail is not available when viewed remotely using RealVNC. Resolution When the SmartStruxure License Software application is used, the drop down menu for adding the license detail is not available when viewed remotely using RealVNC. The above example is one scenario. There are a number of other remote control software applications where similar instances may occur. If such an issue occurs, check that the BMS software is functioning correctly by both being viewed and ran in the same environment. Because of the number of different remote control software options that are available, anomalies will prevail.
