Issue The following error message is displayed in the UNC-s Standard Output Window when attempting to install a station: FATAL: Cannot boot station from sns java.lang.ClassNotFoundException: tridium.services.DatabaseService   Environment Niagara R2, UNC-520, UNC-410 Cause A UNC can not be licensed for DatabaseService. Resolution Open the station offline and remove the DatabaseService.

Issue Cannot find the documentation on how to configure and use the Lon over IP interface in a ENC-520 Environment ENC-520 licensed for ENC-DRV-ILON These devices also support the ENC-DRV-ILON license: JACE-6, JACE-7 and JACE-NXT Cause Cannot find required information. Resolution Refer to the section "Components in LonIP Module" in the Lon Components Guides chapter of the NiagaraAX -3x Lonworks Guide. This document is distributed with the I/A Series G3 software (doc folder).

Issue The system is set up to create an alarm file when certain alarms is trigged but no file is created. Environment TAC Vista 5.1.7 Cause For a alarm file to be created when an alarm is set a object called "Alarm Receiver - File" must be created that object must be connected to a "Alarm Control" object, then the alarm which should trigger the file must be connected to that  "Alarm Control" object. The alarm was connected to the wrong "Alarm Control" object.   Resolution Make sure the alarm is connected to the correct "Alarm Control" object.

Issue When previously offline BACnet devices go back online, will the Xenta 913 try to poll them again? How does Xenta 913 poll BACnet devices that have been offline? The Xenta 913 doesn't poll all the BACnet objects when previously offline BACnet devices go back online Environment Xenta 913 BACnet Cause All objects the BACnet objects that can't be polled (are offline) during a poll are moved to a "failed queue". " Every 30 seconds a task moves one input and one output object from the "failed queue" to a different queue so that they will be retried next poll. This is all hardcoded and the 30 seconds timer cannot be changed.   Resolution If you wait long enough, all of the BACnet objects will be polled again. If many devices have been offline, this will take a while though.

Issue Are examples available to show how to write Plain English programs and create points for a Modbus RTU X Driver linked to Schneider Electric Power meters? Environment Modbus RTU X Driver Schneider Electric PM800 Power meters. Cause How can Modbus RTU X-Driver programs be written to poll for the data in a 3rd party Modbus device? Resolution The attached example show how to use the modbus RTU x-driver to read 4 16 bit data values from the PM800 meter, then using plain english to get the values to output to a single infinity numeric the total Power reading in kWH/mWH/gWH depending on the scaling factor of the meter. Create 4 Numerics reading the four registers that are used to store the data. Registers, 1716, 1717, 1718, 1719 are used in the PM800 Then create another numeric and via PE do the following calculation Energy Calc = (Register 4 x 1000000000000) + (Register 3 x 100000000) + (Register 2 x 10000) + Register 1. This will give you the value in wH. Then use a multiplier to give you the final reading in kWH etc.

Issue "Not set" shown in the name column after upgrading to database layout version 2. Environment TAC Vista 5.1.7 or newer SQL taclogdata database layout version 2.0 Cause The "Name" column is a new column introduced in Vista 5.1.7 with the new database layout, so when a database is upgraded no name is added as there is no contact with Vista. Once Vista is running and a value is logged to the trendlog the name will be updated in the "Name" column to the same name as shown in Vista. Resolution No resolution required as the name will be updated once a log value is logged to the log database.

Issue The EmailRecipient is not receiving alarm emails sent by a Niagara G3 station. Environment Niagara G3, ENS, ENC-520, ENC-520 Cause If spam filter is enabled, the SMTP server will not route email as long as the Reply to parameter of the OutgoingAccount is empty.  It will treat the message as spam. Resolution The OutgoingAccount’s “Reply To” field must contain an email address. - Open the station in the tree - Navigate to Config > Services > EmailServices > OutgoingAccount - Fill in a reply to email address in the “Reply to” field.       Note:  In some cases a factious email address of the format xxxx@xxx.comcan be entered.  However, depending on the SMTP server, the "Reply to: field must contain a valid email address on the local SMTP server.

Issue DCX250 goes blank appears to stop operating. Environment Infinity DCX250 Plain English Programs Cause The DCX250 uses Point to Point communications (not Import/ Export) for all of its communications, this relies on the other controllers being online and communicating at that time. Resolution The DCX250 uses point to point comms (not import / export) for all communications with other controllers, this should be done in a single import/ export mapping program to local numerics that is protected by an E: line or a First Aid program. The display programs should then use these local numerics for the screens, this ensures the user interface programs will still operate correctly in the event of a network problem. Also check the Infinet for Reconfigs to ensure network is operating correctly, verify correct cabling and grounding of equipment

Issue What operation modes should be used in zone control then the area is not being used? Environment Xenta 121 FC Xenta 121 HP Cause The TAC Xenta 120 device does not have any internal clock. The actual operation modes has to be sent from another device such as a Xenta 401. The following values could be sent to the nviManOccCmd SNVT: 0=OC_OCCUPIED 1=OC_UNOCCUPIED 2=OC_BYPASS 3=OC_STANDBY other values=OC_NUL 255=OC_NUL Resolution Normally, OCCUPIED mode is used when there are people in the zone. During night time, or short periods without people in the zone STANDBY may be used. If someone enters the area and triggers a motion detector or presses the Bypass button, the mode changes to BYPASS. UNOCCUPIED mode is most appropriate if the area is no longer rented or during some other long period without anyone in the area.

Issue Does TAC Vista Support for trending based on the COV (Change of Value)? Environment TAC Vista Cause Other BMS systems support COV for trending. Does TAC Vista support the same? Resolution No, TAC Vista do not have any provision to trend based on COV. It is only possible based on time interval.

Issue How are the licencing requirements for SQL Server 2008 determined when being used on a Continuum LAN installation with multiple workstations.  Environment SQL Server Continuum Licensing. Cause Determining the licensing requirements for SQL Server can be a very complex undertaking, and not something that we can help you with at Product Support. This is because there are a number of variables that must be factored in to the final determination.  Web servers and Marathon virtual servers add their layer of complexity. Even determining the requirements for a simple multi user LAN system with one database server and ten workstations can be tricky since one has to factor things such as how many processors each machine is running as well as how many machines will be connected to the database.   Resolution The following guide is a starting point. To bid a job however, I would recommend working with Microsoft to determine the requirements. SQL Server 2008 Licensing Guide.pdf

Issue A change is made to a public signal in TAC Vista Workstation, which was created in a Xenta Server XBuilder project, changed back to the initial value after performing a download to this Xenta Server. Environment Xenta Servers (Xenta 511, Xenta 515, Xenta 555, Xenta 527, Xenta 701, Xenta 711, Xenta 721, Xenta 731, Xenta 913) XBuilder Tested with Windows Server 2003, Window XP SP3 Cause If a path name is changed of a signal, for example, change the "the site name" folder name to another name, Vista consider this change as a major change, and Workstation will not be able to find the new path of the signal. Therefore, the signal will return to the initial value which is initialized in the Menta object. Resolution Suggestion is making all the infrastructure change at the beginning if you can. If there is a need to change the path, make sure all the initial values are reflect to the current values in Workstation. Then, make the download to the Xenta Server.

Issue When was the GCS bus controller discontinued? Environment Network 8000 Cause Field request Resolution The GCS controller was discontinued in 2001.

Resolution   Do a full uninstall of Continuum using the following procedure. Uninstall Continuum from Control Panel. Delete  ProgramFiles\Continuum with all files and folders. Delete Andover Controls Folders from the computer registry.  Note: A backup should be made of the registry before making any changes to the registry. Reboot the computer. Logon using a Local Administrator user. From Disable the following services... Virus Protection, Anti-Spyware, FireWall software, Windows Defender, Windows Software Protection Services From User Account Control Settings and set the protection level to Never Notify. Install Continuum.

Issue Some users are unable to see I/NET values on a graphics page displayed in a 527 Environment Xenta 527 TGML Cause User permissions on the 527 must allow the user to access the I/NET links that are being displayed Resolution Log out of the 527 Log in as the root user In the Configuration folder, select User administration Modify the user that was having issues. Click on the ".." link at the top of the folder list till you are in the root folder Click on the "inet" link to modify permissions of the I/NET folder Give the user read and read/write access Save changes

Issue The transmit and receive lights on BCX comm 2 stay lit continuously minutes or hours after the Infinet bus is connected. Environment BCX9640 i2920 Infinet Cause Electrical interference or noise being introduced into the Infinet bus. Resolution Removed the to i2920 controllers from the infinet.  Since these were the only controllers powered by 120 volts it seemed likely that they were a potential source of interference from the power wiring to the Infinet cable. 

Issue How do TAC Vista server trend logs affect the performance of the server and LON network? Environment TAC Vista server LON Network Cause The bandwidth of the LON network is for all communication on the LON wires to share. This includes all graphics, object transfers, etc. Resolution The bottleneck is the communication to the lon network. Depending on what interface (LTA) you are using Vista can handle about 15-40 read/writes per second. Many Vista Server trend logs would increase the amount of information being sent out on the wire and if there is a sufficient number of them, you may see some delays on other forms off communication: i.e., graphics, object transfers, etc.

Issue How many characters can a comment field in TAC Menta have? Environment TAC  Menta Cause How many characters can a comment field in TAC Menta have? If you exceed this length, the application may not work as expected. Resolution There can be 30,000 characters.
