Issue Xenta server stand alone and Vista at the same time. No alarms showing in TAC Vista when Xenta Server is connected. Environment TAC Vista TAC Xenta Server Cause If you add a stand alone Xenta Server on a Lon network it will send out heartbeats just like TAC Vista does. So the affect will be the same as having 2 TAC Vista servers on the same network.  But there is a way to turn this off. In Xbuilder you can turn this off by setting "Alarm Server" to disabled Resolution In Xbuilder click on the LON object Under General properties change "Alarm Server" to disabled. Download the project.

Issue How can a sound or light be triggered when an alarm or alarm type is active. Environment Vista 5.x.x. Cause Vista Server uses two sum alarm objects that control a database points for each alarm priority when they meet the criteria of the sum alarm type. $Acoustic Any alarm in that priority that requires an acknowledgement. If acknowledgement reset is enabled then an alarm will trigger the Acoustic Sum Alarm a second time when it has returned to normal and requires a second acknowledgement. $Optic Active when any alarm in that priority is active or awaiting acknowledgement from a return to normal condition. Acknowledging the alarm does not stop the Optic Sum Alarm. Resolution To configure a sum alarm for control of physical objects such as a buzzer or light first setup the alarms to use a specific alarm priority. Select either the $Acoustic or $Optic sum alarm in the TAC Vista folder or the Vista Server object and select the properties of the sum alarm object. Select the browse button next to the priority of the alarms that match your criteria and browse to the database point that will trigger control logic or a physical output that results in an audible buzzer or a visible light. To send a value to multiple controllers use an internal database point then use Object Transfer to send it to multiple controllers for control of physical equipment.

Issue The ScreenMateCache.dat file is not created on a Windows 2008 server.  Environment Windows 2008 server Vista 5.1.6 Cause In a 2008 server the ScreenMateCache.dat file is created in C:\windows\temp, to get it working the user "Network service" and "Local system" needed full access to this folder.

Issue Are there any specific setting to be enabled in order for restricting the access to TAC Vista database folders? Currently all windows users can copy the TAC Vista database folders.   Environment Vista 5.1.6 Cause The only way to restrict the access to Vista database folders is to create a special Windows user which have full access to the folders and then the Vista server must run as a service logged on with this Windows user. Resolution Create a special Windows user which is administrator on the PC, run the service Tacos with this user. Restrict the access to the database folders for all other Windows users.

Issue What is the purpose of Acknowledge Reset and how can be it be configured in Vista? Environment Vista 4.x.x/5.xx Cause Acknowledge Reset is a feature that requires an alarm to be acknowledged after it has returned to normal. Purpose This feature is used to help match an end user operating procedure that requires time stamped and user id recording of when an alarm is acknowledged and when the problem condition is corrected. In combination with the Acknowledge Response feature the Vista event log can be used as a maintenance log of the system. Behavior There are two sequences that activation of the Acknowledge Reset will cause and the default colors assigned to each state. Single Acknowledgement Alarm goes into the alarm condition, but it is not acknowledged. - Alarm displayed in red with alarm string Condition returns to normal - Alarm displayed in red with reset string User acknowledges the alarm and it is removed from the alarm pane. Double Acknowledgement Alarm goes into the alarm, condition. - Alarm is displayed in red with alarm string. Alarm is acknowledged - Alarm is displayed in green with alarm string. Condition returns to normal - Alarm displayed in yellow with reset string. User acknowledges the alarm as second time and it is removed from the alarm pane. Each alarm priority can be individually enabled or disabled with the Acknowledge Reset functionality. Resolution To enable Acknowledge Reset: Select "TAC Vista" in the Vista Workstation tree structure. Right click on the $System object and select properties. Select the Priority tab. Check the box next to each alarm priority Acknowledge Reset should be enabled for.

Issue DDC Lines show only inconsistently when viewed through a Xenta 527 Web Server Graphic Environment I/NET Xenta 527 5.1.3 and below Cause Issue corrected in 5.1.4 release Resolution Upgrade the Xenta 527 to the latest revision of I/NET or at least 5.1.4 Upgrade Xbuilder to the exact same revision Send the upgraded project files to the upgraded controller.

Issue Dynamic values Change of state alarm with dynamic values alarm text Environment Vista Cause Want a state of change alarm text to show a dynamic value Resolution To present additional information on an alarm when it appears in the alarms list, such as a temperature reading for a high temperature alarm, dynamic values can be included in the alarm text. The character @ followed by the identity of an object can be used in alarm texts to present the value of the object (the standard property), according to the syntax “Alarm text @object-ID “. You may also single out a specific object property by adding a dot and the name of the property, according to the syntax Alarm text@object-ID.mnemonic1 This function is very useful if you want to present additional text with, for example, the description or a measurement unit of an object in the alarm text. Note: Priority "Info" will not work since this is a message priority and not a alarm priority

Issue When a Vista Master Slave network is setup the Slaves folder list appears but no objects in the folders. Environment Windows 7 32 bit Vista 5.1.X Cause Sometime the synchronies process does not fully complete between the Master and Slave servers. Resolution A restart of the Sever and Slave helps this process to complete. Shut both computers down and then start the master computer and Vista server. Once the master server has been started and checked for correct local communication start the slave computer and Vista server. Wait for the master to pickup the slave and recheck that the objects are being displayed. Also check that the Vista server name matches the computer name as this can cause similar problems.

Issue If having a Vista network and a OPC server installed on one Vista server can a OPC client connecting to the OPC server read values from another Vista server in the network?  Environment Vista 5.1.6 OPC server 1.6.2 Cause No it is only possible for the OPC client to read values on the Vista server where the Vista OPC server is installed. This is to avoid a lot of communication between the Vista server nodes which is pretty slow. Resolution Install a OPC server on every Vista server.

Environment XBuilder 5.x.x Xenta 511, 527, 701, 711, 721, 731, 913 Cause An enumeration must be configured in Xbuilder that defines the text that will be shown with each value. Resolution In Xbuilder create a new Enumeration Under the Tools drop down select Enumerations. Click the new button in the Enumerations section and provide a description for the enumeration Highlight the enumeration created and click the new button in the Definitions section. Type the text string used for each value. Click Ok. Set the point to use the enumeration. Highlight the point that you want to use this enumeration.

Issue Xenta 104-A will control heating outputs but not cooling outputs. Environment Xenta 104-A Cause U1 is setup as a discharge temperature sensor if the outside air is bound into the controller. Resolution If the outside air is bound in as a SNVT connection and Bit 4 on nciAppOptions is set to on. When this occurs, U1 terminal 7 and 8 on the 104 become a Supply temperature sensor. If no 1.8k resistor is installed across these terminal the Supply temperature will read less than 0 causing the controller to think no cooling is needed as the supply temperature is so low. Install a 1.8k temperature across terminal 7 and 8 and this will allow normal control of the Xenta 104-A controller.
