Issue How can the information displayed in an alarm-generated email message be controlled in Niagara R2? Product Line TAC IA Series Environment Niagara R2 Cause The content of alarm-generated email messages is determined by the AlarmFields property in the MailRecipient object configuration. Resolution To customize the information displayed in alarm email messages: In WorkPlace Pro, locate the MailRecipient object. Right-click the object and select Properties. Go to the Config tab. Under AlarmFields, select the text fields you want included in the email body. Click Apply to save changes. The email will now contain only the selected fields.

Issue Temperature values from an I/A Series Micronet LON controller appear in Fahrenheit within an I/A Series R2 UNC station, even though the default unit of measure is set to Metric in WorkPlace Tech. Product Line TAC IA Series Environment I/A Series R2 Micronet LON Controllers (MNL) Cause The LonWorksService in the UNC station converts SNVTs defined as temperature to Fahrenheit when the temperatureUnits property is set to Fahrenheit. This occurs regardless of the Metric setting in WorkPlace Tech. Resolution Update the temperatureUnits property in the LonWorksService to Celsius: In the UNC station, right-click LonWorksService and select Properties. Navigate to General > Config tab. Change temperatureUnits to celsius. Click Apply. Note: When set to Celsius, no conversion is performed; values are assumed to be in degrees Celsius as per LonTalk protocol. If set to Fahrenheit, SNVTs defined as temperature are converted accordingly.

Issue When integrating a ProView display into a Niagara R2 UNC for the first time, which Lon JAR files are required? Product Line TAC IA Series Environment Niagara R2 ProView display Cause The integration requires specific Lon JAR files and wizards to enable communication and configuration between the ProView display and the Niagara R2 UNC. Resolution Ensure the following JAR files are installed in the UNC: lonDistech-2.307.529.v1.jar lonDistechWizards-2.306.515.v111.jar wizard-2.301.529.v1.jar lonworks-2.301.529.v1.jar Additional Notes: These files must match the Niagara R2 version for compatibility. Refer to the Niagara R2 documentation for steps to install JAR files in the UNC.

Issue Is there a way to keep resending alarm notifications in Niagara R2 until the alarm is acknowledged? Product Line TAC IA Series Environment R2 WorkPlace Pro (all versions) Cause The system does not include a built-in mechanism to automatically resend alarm notifications for alarms that remain active and unacknowledged. Resolution Niagara R2 does not provide a way to resend an alarm that is already in an alarm state until it gets acknowledged. Once an alarm is generated and the notification is sent, it will not automatically resend unless the alarm transitions back to normal and then returns to alarm state. For repeated notifications, consider implementing external logic or using Niagara G3 (which supports this feature).

Issue A Cisco Mediator BACnet/IP controller connected to a Niagara R2 UNC can read exposed BACnet objects but cannot overwrite setpoints or issue commands. Product Line TAC IA Series Environment Niagara R2 all versions Cause The Niagara R2 station requires a specific BACnet user configuration to allow external BACnet devices to write values or send commands. Without this user, write requests are rejected. Resolution Create a special BACnet user in the Niagara R2 station: Open the Niagara R2 station configuration. Navigate to Security → Users. Add a new user with the following properties: User Type: BACnet Assign appropriate permissions for writing to exposed objects. Save and restart the station if required. Refer to Tridium BACnet Integration Guide, pages 4-6 and 4-7, for detailed steps.

Issue Can the Niagara R2 MailService (SMTP) port number be changed to something other than its default port 25? Product Line TAC IA Series Environment Niagara R2 CoreRuntime 2.301.429.v1 and later Cause Local IT policies may require SMTP messages to be sent on a port other than the standard port 25. Resolution Starting with CoreRuntime 2.301.429.v1, MailService supports custom SMTP ports. To configure: Navigate to Service container → MailService Properties → Config tab. In the smtpHost property, enter the SMTP server address in the following format: hostname:port Examples: ourMailSrv:40 10.10.9.4:40 Restart the station after making changes. If the port number is omitted, MailService defaults to port 25.

Issue When tunneling through a UNC (Niagara R2) or ENC (Niagara G3) to an ASD bus using XPSI, communication timeout errors occur. Product Line TAC IA Series Environment PSI/XPSI software (any version) UNC (R2) or ENC (G3) with ASD bus connected Serial tunnel client (R2 or G3) Cause Delays introduced by the Internet between the PSI/XPSI computer and the remote tunnel client can result in communication timeout errors. These delays affect the ASD bus communication speed. Resolution Set the baud rate of PSI/XPSI to 1200 to minimize or eliminate timeout errors: Open PSI/XPSI software. Navigate to Site Setup Configuration. Set Baud Rate = 1200 as recommended in the TAC I/A Series Enhanced ASD Driver Engineering Guide (F-27429, Chapter 5, Table 5.1). Reference: TAC I/A Series Enhanced ASD Driver Engineering Guide, F-27429.

Issue Need to visually indicate when a linked object is in an override condition by changing the color of a GxText object in Niagara R2 graphics. Product Line TAC IA Series Environment Niagara R2 WorkPlace Pro graphics using GxText objects Cause Operators require a clear visual cue on graphics when an object is overridden. By default, GxText does not automatically change color based on override status. Resolution Niagara R2 provides objects in the programLib JAR that can detect override conditions and trigger color changes: Detect Override Condition Use objects from programLib/hvac folder: AoCheckForOverride BoCheckForOverride These objects output a Boolean flag when an override exists. Change Color on Override Use objects from programLib/util folder: ColorOvBinary ColorOvFloat Connect the priority input of these objects to the overridden object. When an override occurs, the linked object changes color (e.g., magenta). Update GxText Modify the Active Text as needed. Connect the color-changing object to the GxText on the graphic. The GxText will now change color when the override condition exists.

Issue Need to change the booleanKey property value from “overridden” to “value” for hundreds of GxBoolean objects. Is there a way to update multiple objects simultaneously without editing each one individually? Product Line TAC IA Series Environment Niagara R2 (all versions) Cause Manually updating each object’s property is time-consuming. Niagara R2 includes an AdminTool utility that provides an admin-level command to Search and Replace property values across multiple objects in the station database. Resolution Locate AdminTool Found in the Local Library: tridium/apps/AdminTool (JAR file). Add AdminTool to Station Copy the AdminTool app into the station. Configure AdminTool Open AdminTool and go to the Config tab. Set parameters as follows: rootNode: /db/ propertyName: booleanKey elementName: (leave blank) newValue: Value recurseChildren: true Explanation: When set to true , the tool will traverse all child nodes under the specified rootNode and apply changes to matching properties. If set to false , only the root node is modified. objectTypeFilter: (optional) nodeNameFilter: (optional) propertyValueFilter: (optional) Execute Search and Replace Right-click AdminTool and select searchAndReplace. All GxBoolean objects’ booleanKey will now be set to “value”. Additional Info: Refer to WorkPlace Pro Help: Help > Index > General Index > AdminTool for more details.

Issue Niagara R2 is installed on a computer, but the HostId is unknown. The user needs an alternative method to find the HostId without accessing the license.properties file. Product Line TAC IA Series Environment Niagara R2 Cause The HostId is required for licensing or troubleshooting, but the usual method (checking license.properties ) is unavailable. Resolution Open the Niagara Console (found in the Niagara R2 Program Group). Type the following command: nre -hostid Press Enter. The HostId will be displayed on the screen. Additional Info: The nre command can also display other system details. Use nre -help to view available options.

Issue The following issues have been seen when attempting to add and generate SSL Certificates via Device Administrator. Servers appeared as "unknown” in the Device Administrator server list, even though the certificate state is shown as "OK”. (green tick) The Server Certificates option is greyed out. Selecting Server Certificates in Device Administrator (when available) displays an error: Unable to get certificates from the device. Reason: Failed to read property ~/System/Security Manager/Certificates/ActiveCertificate. AttributeError: 'ConnectionRefusedError' object has no attribute 'library.' Product Line EcoStruxure Building Operation. Environment EcoStruxure Building Operation server Building Operation Device Administrator Certificates enabled; HTTPS required end-to-end Cause The issue occurs due to an HTTPS port mismatch: Servers were added in Device Administrator using port 443, but were actually communicating on a different HTTPS port (e.g., 445). This port change is typically made via the Communications tab in WorkStation and does not automatically update in Device Administrator. Device Administrator does not validate the HTTPS port during server addition because it uses SSH and admin credentials for initial connection. However, certain features (such as certificate management) require the correct HTTPS port to be configured. Resolution From WorkStation check the Communication tab for all servers: Ensure HTTPS is enabled between all EBO servers when using certificates. Confirm the active HTTPS communications port configured on each server (e.g., 445) In Device Administrator On affected servers, remove and re-add them in Device Administrator using the correct HTTPS port. After re-adding, manage Server Certificates in Device Administrator as usual. See: Certificates Managed using Device Administrator Certificates Managed Using WorkStation Additional Note: Changing communication ports impacts connectivity and certificate bindings. Before modifying ports, confirm firewall rules, service bindings, and any reverse proxies. Always perform changes during a maintenance window and ensure full backups are available.

Issue BACnet controller objects that have not been overridden appear in purple on I/A Series R2 graphic screens, indicating an override condition incorrectly. Product Line TAC IA Series Environment I/A Series R2 graphic screens BACnet controller inputs displayed on Niagara graphics MNB controller firmware version 1.2 or higher Cause Purple color indicates the BACnet OVERRIDDEN flag is set to TRUE. This behavior is normal and results from compliance with BACnet Specification 135-2004 for BTL certification. Read-only BACnet objects (e.g., Analog Value, Binary Value) must indicate an override condition because their Present Value cannot be changed via BACnet services. Niagara interprets this as overridden, even though it is simply read-only. Resolution Two approaches to prevent purple override indication: Buffer the Value Using Native Niagara Objects Use a Niagara AI object to display the value without transferring the override condition. If BACnet points are in a poll-on-demand container, add a gx type object linked to the BACnet point (invisible) to initiate polling. Display the value using another gx object linked to the AI object. Disable Status Color on GxText Objects Configure the statusColorEnabled property of the GxText object to false. This prevents the purple background from appearing.

Issue Enterprise Server displays repeated warning messages: Lost Sync with system clock - resetting control engine Product Line TAC IA Series Environment Niagara R2 Enterprise Server UNC-520, UNC-410 controllers Cause The warning occurs due to incorrect or inconsistent time synchronization settings between the Enterprise Server and UNCs. This can result from: Improper serverEnabled or clientEnabled configuration Missing or incomplete time protocol server entries Tight clientResetTolerance values Resolution Verify and adjust the following settings: Enterprise Server (ES): serverEnabled = true if syncing with UNC clientEnabled = true if ES gets time from an internet or site server; otherwise set to false clientResetTolerance : Default is 30 sec (too tight). Set to 60 sec or more (enter value in seconds) timeProtocolServer* : If clientEnabled = true , all three slots must contain a time server address. If only one server is used, repeat the same address in all slots. No blank slots allowed UNCs (TimeSyncService): serverEnabled = false clientEnabled = true clientResetTolerance : Same as ES (≥60 sec) timeProtocolServer* : Same rule as ES Reboot the UNC after making changes

Issue The I/A Series R2 (Niagara) Enterprise Server displays the error: ERROR: Cannot subscribe: Invalid node: (specifies node) Product Line TAC IA Series Environment I/A Series R2 Enterprise Server Cause This error occurs due to invalid subscriptions (swids). It typically happens when the parent container or object name on the UNC is changed without deleting and recreating the associated external link. The swid name changes, but the external link still references the old, invalid swid. Resolution Review the links specified in the error message. Identify any external links referencing outdated swids. Delete and recreate these links to ensure they point to the correct node.

Issue How can the entire I/A Series R2 Error Log, Audit Log, or any other system log be saved to a text file for easier review? Product Line TAC IA Series Environment I/A Series R2 Niagara (2.15 or later) Cause Log data often spans multiple screens, making troubleshooting cumbersome. A text file format allows easier searching, filtering, and sharing of log information. Resolution Access the UNC or Enterprise Server via a web browser using: http://<ipaddress>/log/index Replace <ipaddress> with the device’s IP address. Log in using the station username and password. The Log Index page will display available logs (e.g., ErrorLogService , AuditLogService ). For the desired log, select a display format such as: text/plain text/comma-separated-values text/tab-separated-values The log contents will appear in the browser. Use File > Save As to save the output as a text file. Example: Selecting text/plain for ErrorLogService generates a file with entries like: 2011-04-15T09:22:19.59-5,MESSAGE,/LON_BACnet_522services/ErrorLogService,ErrorLogService installed 2011-04-15T09:22:38.89-5,MESSAGE,/LON_BACnet_522,Station started successfully. (HTTP port=80)

Issue When attempting a device browse in Workplace Tech 5.10.1, an error pop up, "CoCreateInstance(CLSID_RTApplication) failed" is invoked A critical error with Rtmonitor.exe when running Workplace Commissioning Tool Product Line TAC IA Series Environment Workplace Tech => 5.10.1 Workplace Commissioning Tool => 5.10.1 Windows OS 32 bit Cause Environment Variables /variable/path includes the incorrect path to the LonWorks\bin. This doesn't allow the rtmonitor.exe to be executed. Resolution When the Workplace Tech 5.10.1 bundle of applications are installed, the Environment Variables is modified to include, %ProgramFiles(x86)%\LonWorks\bin In a 32 bit OS, this ProgramFiles(x86) folder does not exist. This path has to be modified so the assets can be found. Remove the "(x86)" so the path appears as below. Note: This is only applicable for 32 bit operating systems.

Issue When saving station information in the Niagara Application Tunneling dialog window, the following error occurs: “Windows Shell Common DLL has stopped working.” This prevents proper configuration of the tunnel client. Product Line TAC IA Series Environment I/A Series R2 LON Tunnel Client I/A Series R2 Serial Tunnel Client Cause The issue is due to compatibility between the I/A Series R2 Tunnel Client DLL files and Windows 7 operating systems. Resolution Configure the Niagara Application Tunneling dialog box with the required station information: For Serial Tunnel: Select a valid COM port and enter host address, username, and password. For LON Tunnel: Select a valid LON port and enter host address, username, and password. Ensure the tunnel client is set to Silent Mode. Click OK to save the data. When the dialog box appears indicating Windows is checking for a solution, select Cancel before the timeout that prompts to “Close Program.” This action saves the station information successfully. Note: This is a workaround for Windows 7 compatibility issues.

Issue The BACnet Ethernet driver on an I/A Series R2 Enterprise Server cannot open the Ethernet device, preventing BACnet over Ethernet communication. The following error appears in the station's Standard Output: ERROR: Cannot start Ethernet Packet Driver tridium.nre.DriverException: Cannot open \\Device\\E100B1 [ethernet] Product Line TAC IA Series Environment I/A Series R2 Enterprise Server BACnet Ethernet communications Cause BACnet over Ethernet requires a special low-level network access driver. If this driver is not installed or configured correctly, the Enterprise Server cannot establish BACnet Ethernet communication. Resolution Verify that BACnet Ethernet communication is required for your application. Install and configure the host link-layer support driver as described in the BACnet Supervisor Reference: Refer to pages 1-20 to 1-24 in the BACnet Supervisor Reference. The document is located in: \\niagara\\docs\\BACnet Restart the Enterprise Server after configuration changes. Confirm that the Ethernet device is accessible and properly bound to the BACnet Ethernet driver. Note: This step is only necessary when using BACnet over Ethernet. For BACnet/IP, this configuration is not required.

Issue The R2 ASD (IbsASD) driver may fail to communicate correctly with ASD devices if not configured properly. Product Line TAC IA Series Environment R2 ASD (IbsASD) driver (all revisions) Cause Incorrect driver configuration settings can lead to intermittent or failed communication with ASD devices. Resolution Configure the driver using the following recommended settings: General / Engineering retryCount = 3 responseTimeout = 2 sec Poll / Config cycleTime = 333 ms × number of devices on the ASD bus (Approx. 3 devices per second) Comm / Config commPort = COM4, COM5, COM6, or COM7 (depending on port used) maxBaudRate = 19200 (Use 9600 if PEM1 controllers exist on the ASD bus) DeviceStatus / Config deviceStatusPingDelay = 60000 ms Tip: Always verify baud rate compatibility with connected devices and ensure proper port selection for stable communication.

Issue How can a Niagara R2 UNC be configured to monitor the DI1 and DI2 contact status of a Viconics VT7600 Series Lon thermostat? Product Line TAC IA Series Environment Niagara R2 UNC Viconics VT7600 Series Lon Thermostat Cause The VT7600 thermostat reports its digital input (DI) statuses within a single SNVT (nvoSccStatus). These bits are not directly exposed in the UNC without additional configuration. Resolution Ensure the VT7600 shadow object is commissioned in the UNC. Open the Workspace Editor and navigate to the page containing the VT7600 shadow object. Go to /tridiumx/lonworks/conversion and copy the DynamicDemux object into the Workspace. Link the VT7600 shadow object to the DynamicDemux object: Under VT7600 column, select nvoSccStatus. Under DynamicDemux column, select link and click OK. The DI statuses are mapped as: DI1 → bit18 of nvoSccStatus DI2 → bit17 of nvoSccStatus Link these bits to the desired monitoring objects in the UNC. Tip: The DynamicDemux object allows individual bits from SNVTs to be exposed for monitoring, making it ideal for handling composite status points.
