Issue Pin configuration of the RJ10 for TAC Xenta OP Product Line TAC Vista Environment Xenta OP Cause The Xenta OP has two connection methods, the 4 pin terminal blocks and an RJ10 port. Some users may have the need for making custom RJ10 cables. Resolution The pin order for the RJ10 port is the exact same as the order on the terminal block right next to it. From right to left they are: C1 (comms 1) C2 (comms 2) G+ (24 VAC power) G0 (24 VAC ground)

Issue Is it possible to convert a Xenta 121-HP to a Xenta 121-FC? Product Line TAC Vista Environment Xenta 121 Cause The hardware controller was purchased as a heat pump or fan coil unit, and the opposite is needed for the software application. Resolution As of August 2011, it is possible. Download the NXE file and XIF file for the desired application Download the files to the Xenta 121 using Lonmaker or NL220 This will be blocked in the future.

Issue Show the actual value of the point being monitored in a Vista Alarm. Example: A temperature is monitored for a high temperature alarm In the Vista alarm properties, under the Alarm tab, is "Text for Tripped Alarm" and "Text for Reset Alarm" When the alarms trips, the Vista alarm queue should read "High Temperature of 77" Product Line TAC Vista Environment Vista Workstation Alarm queue Cause The fact that an alarm has occurred can be enhanced by displaying the value that caused the alarm to trigger. For example, the room temperature at the time of the high temperature alarm. These values will then be recorded in the event log as well. Resolution Enter the descriptive text into "Text for Tripped Alarm." In this example, "High Temperature of " Go to the Object tab in the Alarm Properties window and copy all of the text in the Object to monitor Go back to the Alarm tab in the Alarm Properties window and at the end of the descriptive text add an @ symbol and paste what you have copied from the Object to monitor. For example: High Temperature of @VISTASERVER-LTA-LNS-XG-AHU1-SUMMARY-R_T This will be displayed in the Vista alarm queue as: High Temperature of 77 If it reads ??### instead of the value, add ".PV" to the end of the absolute path High Temperature of @VISTASERVER-LTA-LNS-XG-AHU1-SUMMARY-R_T.PV NOTE: the actual value may not be displayed in the Event window before Vista 5.1.7 (Vista 5.1.7 is included).

Issue Trying to upgrade to Vista 5.1.2 but the following error is displayed and the application will not install: Unable to connect to SQL Server: (local)\TACVISTA ([0] Cannot generate SSPI context) Product Line TAC Vista Environment Vista 5.1.2 Server/Workstation Installation Cause When you first run the Vista 5.1.2 file it should uninstall previous versions of Vista, which it does but it does not uninstall the hot fixes. Resolution Uninstall the Vista hot fixes through the add/remove programs in the control panel Run the TACVistaServer512 file again.

Issue Xenta 121-FC fan runs in cool mode even though cool mode is not used. Product Line TAC Vista Environment ZBuilder Xenta 121 Cause Previous settings configure the cooling in such a way that the Xenta 121 runs cooling outside of cooling mode. Resolution In ZBuilder > Sequences > Fan, confirm that "Run in min speed if no cooling is configured" is unchecked In ZBuilder > Sequences > Cooling, set the Cooling from "Not used" to "On/off" Change the Activate at from 0% to 100% TL Go back and set the Cooling to "Not used" Apply/Save changes and the fan should not cycle on in cool mode

Issue Negative values are displaying *** asterisk instead of the value. Product Line TAC Vista Environment XBuilder 1.6 Vista 4 OGC Graphics Cause To display negative values in XBuilder, add a placeholder for the negative value. Resolution In the example of terminal load, the lowest expected negative value is -100. This will require an integer value of 4 in the graphics editor in order to display -100. If you the integer value is set to 3 and the value goes to -100, the display will show *** . This indicates the value is out of range according to the parameters set.

Issue 102-AX plug-in will not calibrate airflow, but on the Status page the airflow setpoint changes, but the damper position doesn't. Product Line TAC Vista Environment Xenta 102-AX firmware versions prior to 2.1.6 Cause Firmware versions prior to 2.1.6 had a bug in the airflow calibration functionality. The damper will not modulate to maintain the desired flow (low/high) thus preventing calibration. Resolution If your 102-AX is at a firmware version below 2.16: When you start calibration through the plug-in the airflow setpoint will go to minimum flow; however, the damper position will not change once you start calibration (Note: It used to work in earlier versions). Leave the unit in calibration, go back to the Status tab and override the damper. Adjust it until you reach the cooling low flow setpoint, then take the airflow reading and enter your low airflow reading. Now modify the damper position to maintain airflow near the high airflow setpoint, take the airflow reading and enter in your high airflow reading. The box should now be calibrated, remember to take the damper position out of override so the damper can modulate as needed. This issue has been corrected in 102-AX firm version 2.16. You can also upgrade the firmware and the calibration through the plug-in will work as expected.

Issue A Xenta 5/7/9xx used as a LON node is not showing data from Xenta programmable controllers, but the values are working in Vista and LonMaker. SNVTs from ASCs are showing up correctly in the Xenta 5/7/9xx. Product Line TAC Vista Environment LonMaker 3.1 XBuilder 1.6 Xenta Server Xenta 511, 527, 701, 711, 721, 731, 913 Xenta programmable controllers Xenta 280, 281, 282, 283, 300, 301, 302, 401, 401:B Cause If the LNS database that is browsed into the XBuilder project has programmable controllers with spaces in the names, they will not show data properly. Resolution Go back into LonMaker and rename all programmable controllers that have a space in the name. Example: Use an underscore in place of every space. Update the Vista database Reimport the LNS database into XBuilder Download the Xenta 5/7/9xx

Issue XBuilder and Port Forwarding Product Line TAC INET, TAC Vista Environment I/NET or Vista site Cause Desire to know XBuilder and Port Forwarding Resolution A Xenta 511/527 can be downloaded: On the intranet using the actual 511/527 web address Remotely using the public IP address Using port forwarding by typing in the :9080 (or whatever ports are assigned) after the web address in the XBuilder project. You will have to change the http and https ports in the XBuilder project to the remote ports.

Issue Xenta 511/527 with Port Forwarding - Login allowed but after login page times out and page cannot be displayed. Product Line TAC Vista Environment Xenta 511 Xenta 527 Cause Firewall/router settings must be adjusted by the site administrator to accommodate the redirect. Resolution Tell the router/firewall administrator that the 511/527 redirects ports from https to http so you will need the firewall/router setup to accommodate this. If there is a delay in getting this done, the work-around is to type in the missing redirect address. For example your ports are https - :9443 and http - :9080. Login to the 511/527 https://xxx.xxx.xxx.xxx:9443/www/index/Slogin.html the 511/527 redirects you from https to http and it will not get the redirect with the "Button" and you will get http://xxx.xxx.xxx.xxx:9080/www/index/index.html After the last "/index" type in "Button" so the link looks like below http://xxx.xxx.xxx.xxx:9080/www/index/indexButton.html and type enter. You'll now be able to navigate as usual in the 511/527.

Issue If there is no saved copy of an XBuilder project and the backup was not sent to target it may still be possible to recover some of the data to be able to reconstruct the project Product Line TAC INET, TAC Vista Environment Xenta 5xx / 7xx / 9xx Cause Lost XBuilder project and backup was not sent to target Resolution With XBuilder 1.5.0 or later connect to the Xenta controller through the web interface and use the Utilities > Project Tree to view the project information. Use this information as a blueprint to rebuild the XBuilder project. If an older version of XBuilder was used then can connect to the Xenta Server with FTP. The OGC graphic files as well as the CFG files which configure the linking of points and signals can be obtained through the FTP. These files can then be imported into a new XBuilder project which can be sent to the Xenta Server.

Issue TAC Xenta 511/527 Help cannot be opened. Product Line Satchwell MicroNet, TAC INET, TAC Vista Environment I/NET or Vista site Cause TAC Xenta 511/527 and the Help information will not open Resolution With the new product versions of the 511/527 the help file is now downloaded to the computer rather then viewable online. If you receive an "Action canceled" error when you try to open the help file right click on the file (Help511-527.chm) and choose "Properties". Then under the General tab at the bottom of the window you will see "Security: This file came from another computer and might be blocked to help protect this computer." Click "Unblock" and then open the file and you should be able to view the help section. This error message appears to only occur when downloading the help file with Internet Explorer.

Issue Xenta 511/527 - values/trend logs have exponential numbers, menu tree is black blocks and other problems Product Line TAC INET, TAC Vista Environment I/NET Site Cause More than likely Java has been updated without the end user realizing it. Uninstall Java and then reinstall from the link provided in the 511/527 menu tree. Resolution Click on Help. If a pop-up blocker is installed, hold down the Ctrl key while clicking. Click "Day to Day Operations", "Java Plug-in", and finally "Download Java Plug-in". This will give you a list of java downloads to select from depending on which TAC product you are trying to use. Disable automatic updates in Java so this does not continue to happen. Right click on the Java icon in the lower right hand side of the screen Left click on Open Control Panel Right click on the Update tab Uncheck the box next to Check for Updates Automatically Click Apply and close out of Java.

Issue 101-VF/24 (Fan coil controller) allowing positive terminal load with cool air supply and one valve for heat. Product Line TAC Vista Environment 101-VF/24 101-2VF 101-2VFC Cause If you have a single valve application such as radiant heat control, but you have a central system that brings in fresh/cooled air to the same space, you may want to use the terminal load in the central system to indicate a call for cooling. Resolution If you only configure the controller for one valve and set the water temperature and water temperature setpoint to only allow heating operation, then the terminal load will only be calculated from 0 to -100% (heating only). Nvo_unitStatus will stay in heat mode as well even if the room gets too hot. If you configure it up for two valves then your terminal load will be calculated from 100 to -100%, indicating both heating and cooling load.

Issue Using "Add All" can save time when making bindings in LonMaker. Product Line TAC Vista Environment LonMaker SNVT Bindings Cause Multiple SNVT bindings in LonMaker can be time consuming to create but you can speed up the process significantly on some of your one-to-many bindings. Resolution For example say you have one Occupancy signal to pass to all or most of your controllers. After selecting your hub connection (the nvo_occupancy) in the Network Variable Connection dialog, and clicking "Add FB/SN's..." you'll see your subsystems. Select a subsystem that you know you want the SNVT to be passed to, right click on that subsystem and select "select all." Once you have added the functional blocks to the Target window and clicked on one of the target inputs, you can select the "Add All" option to select every network variable that matches the currently selected target in all of the other functional blocks. This process will verify that the variables are the correct variable type and direction. Now that you have a one-to-many binding you need to determine which of them need to be removed, e.g. the nviOccupancy on the controller whose nvo was the hub. After a final pass through you can select the "OK" button to complete the binding process.

Issue How many stages of heating can be used with a Xenta 102-AX? Product Line TAC Vista Environment Xenta 102-AX Cause A Xenta 102-AX can be configured in the plug-in for up to three stages of heat, but there are only two heating outputs. Resolution The 102-AX can be used with up to 3 stages of heat. First stage is one strip Second stage turns off the first strip and energizes the second strip Third stage turns on both strips. This can be utilized very nicely for boxes where, for example, the first stage is 3kW and the second is 6kW. The third stage would provide 9kW. Refer to the 102-AX Software and Hardware Reference Guide Chapter 2 page 21.

Issue A Vista alarm set up to display a value (such as the temperature being monitored to trigger the alarm) is coming through with question marks where the value should be. Product Line TAC Vista Environment Vista Workstation Alarm queue Cause By default Vista should read the .PV when no other attribute is defined, but sometimes it does not. Resolution Add ".PV" to the end of the text string to display the value.

Issue Download a phone number to a TAC Xenta 901/401/30x using TAC Vista 2000 Environment TAC Vista 2000 TAC Xenta 901, 401, 301, 302 Cause Download a new phone number to the controller to enable communication via the modem COM port. Resolution Open the Status dialogue Right click on the network object Choose download parameters only. This will download the phone number you have defined in your modem COM port.

Issue Routers / i.Lons configured as repeaters pass everything and consume bandwidth causing throughput / slowness issues in your system. Environment LON physical layer L-IP routers Cause The cause of throughput/slowness issues in a network might be that it is bogged down with needless communication. Resolution Configure router ports as "Repeater" to avoid channel conflicts during the construction phase of a project. After all of the nodes are commissioned, configure all routers as configured routers so that they only pass what is necessary upstream. This is especially important if using i.Lon 1000s, 600s, or Loytec L-IP routers as they will pass that unneeded data onto the ethernet.
