Issue The alarm handling between TAC Vista and Xenta 913, 5XX, 7XX acting as Xenta Servers stop after 50 days Vista will stop to receive events from Xenta 913, 5XX, 7XX acting as Xenta Servers after 50 days Environment TAC Vista Xenta 511 Xenta 527 Xenta 555 Xenta 913 Xenta 701 Xenta 711 Xenta 721 Xenta 731 Cause The reason for this issue is that TAC Vista sets a time reference to the computer’s internal tick count just before it’s about to rollover (which will happen every 49.7 days).   Resolution This issue has been fixed in TAC Vista 5.1.7 and a hotfix for TAC Vista 5.0.3 is also available upon request from Product Support Services.   Note: Restarting the Vista Server or the PC will also solve the problem, but only temporarily.

Issue The Vista installation procedure completes with errors.  Vista Server and Workstation may appear to be installed but SQL Server Express is not installed. Environment Vista 5.1.7 SQL Server 2008 R2 Express VMWare Player 3,4 Cause The default hard disk space allocated to a guest OS in VMWare Player is 8GB.  When installing Vista 5.1.7 on Windows XP or above this may not be enough space for Vista to install properly.  The OS requires 5-6GB and SQL Server 2008 R2 Express requires 2.2GB Resolution Increase the disk space allocated to the guest OS in VMware Player 1.  Ensure that the virtual machine state is 'Powered Off'.  To change the state, play the virtual machine. Then go to the VMware player 'Virtual Machine' menu and select Power - Power Off. 2.  Choose 'Virtual Machine Settings...' from the 'Virtual Machine' menu. 3.  On the Hardware tab select 'Hard Disk (IDE)' in the device column. 4.  From the Utilities drop-down list select 'Expand...'.  You can then increase the hard disk size in 1GB increments.  I would suggest 10GB as a minimum. 5.  Please note that the additional space is not immediately available to the guest OS.  To claim this space you must run a disk management tool within the guest OS to increase the size of the existing partition on the virtual hard disk to match the expanded size.  Windows Vista and Windows 7 have built-in disk management tools, but on XP you can run third party tools such as Symantec/Norton PartitionMagic, EASEUS Partition Master, Acronis Disk Director and the open-source tool GParted.

Issue When an alarm in Xenta Server or a Xenta device under a Xenta server that are configured to send alarms via mail,  the mail receivers will get  an extra mail when that alarm is acknowledged. Environment TAC Vista TAC Xenta Server Cause This behaviour is due to a bug in earlier versions of the Vista Server software Resolution There is no known workaround to this issue, but it is fixed from Vista v5.1.3 (and later versions),  i.e. an upgrade will solve it. 

Issue The temperature readings from the space temperature sensor on the TAC Xenta 120 device is not stable, is it possible to damp the readings? Environment TAC Xenta 121-FC TAC Xenta 121-HP Cause In some application, it is not possible to get a stable reading from the temperature sensor. Resolution It is possible to activate a filter for the space temperature readings. Set the nciNodeAppOp2.bit14 to 1, this could be done from TAC Vista or from LonMaker. please note that the first bit is bit zero. This will make the device to use 80% of the old value and 20% of the new reading.

Issue Vista IV Error message 'unable to initialize license' when trying to start workstation.

Issue An attempt was made to modify the protocol service type attribute, and that attribute was not specified as configurable. Environment Vista LonMaker SNVT binding types Cause For network variables, the service type can be specified in the connection information in the Neuron C variable declaration. The options are unackd, nackd_rpt and ackd. The keyword config is the default. This allows a network management tool to change the service specification at installation time. The keyword nonconfig indicates that the service type cannot be changed by a network management tool. Resolution Echelon requests to please refer to the Neuron C Reference Guide for more information. To see which binding type is necessary, open the .XIF in a text editor and look for the following definition: XIF Definition of Line 2, Field 5: Default service type to use for connections containing this variable. Set to 0 for acknowledged, 1 for repeated, or 2 for unacknowledged. Created bindings needs to match the type defined in the XIF file.  Right click on the SNVT and go to properties.  Go to binding type.  Ensure binding type is the same, i.e. you cannot bind a Repeated SNVT type to a point that was flagged for only Acknowledged bindings. 

Issue When logging onto Xenta Server's webpage (Xenta 701 and Xenta 721), "The Site Name" folder is missing. Xenta 701 and Xenta 721 cannot display a Value Page though the page has been created in the Xbuilder project. Environment Xenta 701, Xenta 721 XBuilder 5.1.X TAC Vista Workstation 5.1.X Cause Though Xbuilder allows the user to create a Value Page, it will not be displayed on the website. Xenta 701 and Xenta 721 only has "Service" level support of web services, therefore any web content ability is disabled. NOTE: Xenta 913 also only has "Service" level web services. However, Xenta 913 is a gateway; therefore, the Value Page feature is enabled in Xenta 913.  Resolution User can use other Xenta servers such as Xenta 731 or Xenta 913 to have Value Page feature. Or, viewing points values on TAC Vista Workstation.

Issue Vista Workstation displays a data point as a signed integer data type that reads from a modbus device, but the modbus point is defined as unsigned integer data type in Device Editor. When a modbus point's raw value is greater than 32768, Vista Workstation displays a negative value. Environment Xenta Servers Ver 5.1.4 or previous Xenta 511, 527, 555, 701, 711, 721, 731, 913 Device Editor Cause Xenta Servers will read Modbus data as 16-bit signed data, whether the modbus point is defined as 16bit SIGNED or 16bit UNSIGNED in the Device Template. Resolution Upgrade Xenta Servers firmware to 5.1.5 or above; Upgrade Vista software environment to 5.1.5 or above. include  Vista Server, Xbuilder, Device Template, Menta

Issue How do integrate an Xenta 913 in Vista? Do I need to give an IP address as well as a Neuron ID to integrate an Xenta 913 in Vista? Environment Vista 5.1.X Xenta Server 913 (applies to other models) Cause There may be some confusion as to whether an Xenta 913 is considered a LON device or IP gateway in Vista. Resolution If the device is being used as a Modbus\M-bus\C-bus\BACnet client only the IP address is required. In Vista workstation, right-click on the Server object and select New\Device\Xenta Server 913. Give the device a suitable name. Right-click on the device and select Properties. Set the IP address for the device. Right-click on the device and select edit. Configure the device in TAC XBuilder.

Issue Menta file Simulates (F12) and Generates OK and even downloads from Vista apparently OK, but monitored values shown the message 'Failed to read signal'. Connecting to the controller with the serial lead and entering online simulation mode gives a 'PARSER ERROR'. The Memory Usage stats show less free space than would be expected for a file of this complexity. Environment Vista Menta Xenta Cause The Menta file has some corruption that is not visible when viewing the Functional Block Diagram. Resolution Some files may be rescued by copying the FBD into a new empty Menta file: Create a new empty Menta file with the same Device and Program Specifications as the corrupted file. Open the corrupted file in a second instance of Menta. Drag a selection box around the entire visible FBD and enter Ctrl+C to copy. Switch to the new Menta file and enter Ctrl+V to paste the FBD. Please note that this procedure will copy references to named constants across to the new file, but it will not copy the constant definitions. Selecting F12 will highlight the function blocks containing the references to the missing constant definitions.  Edit the block and press 'OK'.  A dialog box will pop up for each constant where you can fill in the value, unit and public parameters.  Repeat this procedure by selecting F12 until Menta enters simulation mode without errors.  You will also need to create the OP tree and any trend logs from scratch. If you are lucky, the new file will download and run without errors.

Issue When running Vista in high security level Vista will add the NT group "Domain admin" as a user group in Vista at startup. Is it possible to avoid this?

This is not possible to prevent.  Resolution Either run Vista in low security level or take away the "Domain admin" group from the administrator group on the computer.

Issue Xenta Server firmware installation takes several minutes before it starts up When launching an installation of the Xenta Server system software it takes several minutes before it starts Environment Xenta 7XX Xenta 5XX Xenta 9XX Cause This rare issue has been seen on some PCs with a huge amount of files in the Windows/temp folder. It could be various other programs conflicting, in one case it has been the process setpoint.exe that was conflicting. Resolution Delete all files in the users temp folder. Here is a sample of the path: "C:\Documents and Settings\user_name\Local Settings\temp" or "C:\Users\user_name\AppData\Local\Temp". Easiest way to access the temp folder is by entering %temp% in the path in explorer. If  setpoint.exe (Logitech) or KiesAirMessage.exe (Samsung) is an active process in task manager, end the process. It has also been seen that the process net.exe is blocking the installer. If the above steps does not work, try stopping that process.

Issue Is it possible to get Host ID locked licenses for Vista IV? Environment TAC Vista IV (Versions 3.30 to 4.50, using the Privilege Licensing system) Cause Since virtualization and other non USB/LPT dongle friendly applications are getting more common, a Host ID locked version of Vista IV is requested.  Resolution Vista IV was withdrawn in the end of 2011. The support is very limited, and Host ID locked licenses are not available. Suggest upgrading site to Vista version 5 where host ID locked licenses are available. Note: Beginning 2012, PSS will no longer support the Privilege License System. The Tamfs26 Server will be retired along with TAC License Server software. It would be wise to inform the customer of this important information to plan for future upgrade in the event that their site license has issues.

Issue Is TAC Vista creating a new IP connection every time it communicates with a Xenta server?   Environment TAC Vista 5.1.7 and earlier versions Cause When TAC Vista communicates with a Xenta server https is always used and a new connection is used every time Vista likes to communicate with the Xenta server. When Vista is communicating with a Xenta 911 http is used and one connection which is connected as long as possible is used even if it is silence long period of times. Resolution When TAC Vista communicates with a Xenta server https is always used and a new connection is used every time Vista likes to communicate with the Xenta server.  

Issue Is LDAP (Lightweight Directory Access Protocol) supported in Vista? LDAP is an application protocol for accessing and maintaining distributed directory information services over an network. Environment TAC Vista 5.1.X Cause Customer has a requirement for distributed directory access on their network. Resolution LDAP is not currently supported in Vista.

Issue Xenta Server Error: Ethernet autonegotiation error (Error#: 59) Environment Xenta Server System Error log Xenta 527 Cause The Ethernet negotiation error comes from bad connection with the Ethernet switch. The negotiation is the low level negotiation between the PHY (physical layer) interface on the Xenta and the PHY on the switch. It negotiates speed (10/100 Mbps ) and duplex. This error can indicate a bad cable or other problems with the switch. Resolution Replace any patch cables Replace connectors on any suspected bad cables Use a different port on the ethernet switch. *Note that the Xenta Server Ethernet port is only capable of 10 Mbps. Speed negotiation is unnecessary if the port on the switch can be manually configured.
