Issue Can I/A Series R2 WorkPlace Pro Alarm Console and G3 Alarm Portal operate simultaneously on the same computer? Product Line TAC IA Series Environment I/A Series R2 Alarm Console I/A Series G3 Alarm Portal Cause The computer should not be running a Niagara station for either R2 or G3. WorkPlace Pro and Workbench (acting as alarm console and alarm portal) do not require the Niagara service to function. Resolution Ensure the computer is not running a station for either R2 or G3. Stop all Niagara services (daemons) and prevent them from auto-starting on reboot. Verify that the following ports are available for the applications: Port 80 for R2 WorkPlace Pro Alarm Console Port 1911 for G3 Alarm Portal Confirm that these ports are open and not blocked by firewall or other services.

Issue In an I/A Series R2 (Niagara) UNC station, attempting to link to the output of a SIM block results in the error: java.lang.NullPointerException . Product Line TAC IA Series Environment I/A Series R2 UNC with the GCM driver Network 8000 SIM-CCN, containing SIM blocks with TYPE = 44 Cause SIM-CCN blocks with TYPE = 44 can be highly customized. Their inputs and outputs may use “data species” that the GCM driver in the UNC does not recognize. The GCM driver has not been tested with any SIM variants (SIM-CCN, SIM-MTECH, SIM-TRANE, SIM-YORK, LNC-100). Resolution Use appropriate Shadow Objects such as: GcmAvParam GcmDateParam GcmDvParam GcmEnumParam GcmIntParam GcmStringParam GcmTimeParam Add APT or DPT blocks to the SIM-CCN database to correctly interpret SIM block outputs for the GCM driver in the UNC.

Issue Need to change the value of the same property across multiple VAV controllers without manually editing each device individually. Product Line TAC IA Series Environment I/A series (Niagara) R2 Cause The site or database contains recurring controllers that require identical property changes. Performing these updates manually for each device is time-consuming and inefficient. Resolution Use the AdminTool servlet located in the Tridium core runtime JAR within the apps folder. This tool enables an online global search and replace of property values. Steps: Locate the AdminTool object in the Tridium core runtime JAR. Refer to the Niagara Standard Programming Reference (starting on page 6-18) for detailed instructions. Configure the search and replace parameters carefully (e.g., names, filters). Best Practice: Set up a test station and validate the search and replace statement before applying changes to the live station database.

Issue The I/A Series R2 Enterprise Server station fails to start and displays the error: fatal boot - file is used by another process station VM Product Line TAC IA Series Environment I/A Series R2 Enterprise Server Cause Multiple stations may be running on the server simultaneously (e.g., autostart enabled). The station may be open offline while attempting to start. Write protection settings on the PC prevent the Enterprise Server from creating or writing necessary files (e.g., config.db.lock , properties files). Resolution Verify Station Instances Ensure only one station is running on the server. Disable autostart for other stations if necessary. Close Offline Station Confirm the station is not open offline when attempting to start. Check File Permissions Navigate to the Niagara directory and verify that all files and subdirectories are not set to read-only or blocked for writing. Remove write protection and ensure the Enterprise Server software has full access.

Issue The Mail Service in a Niagara R2 UNC station is configured correctly, but MailRecipients do not receive emails. The following error appears in the Standard Output Window: javax.mail.SendFailedException: Sending failed; nested exception is: javax.mail.SendFailedException: Invalid Addresses; nested exception is: javax.mail.SendFailedException: 550 5.7.1 Unable to relay Debug logs show: DEBUG SMTP RCVD: 550 5.7.1 Unable to relay DEBUG SMTPTransport: Sending failed because of invalid destination addresses Product Line TAC IA Series Environment Niagara R2 Cause The SMTP server is not configured to relay emails to external addresses. If the recipient email account does not exist on the SMTP server, the message cannot be forwarded. Additionally, if multiple addresses are configured and any one address fails, none of the emails will be sent. Resolution Verify the SMTP server settings: Ensure it is configured to relay emails outside its own domain. Contact the site’s IT department to enable SMTP relay for external addresses. Validate recipient addresses: Remove invalid or non-relayable addresses from the MailRecipient configuration. Test sending an email to a valid account on the SMTP server to confirm connectivity.

Issue When attempting to back up an I/A Series R2 UNC (Niagara) station, the process fails and displays the following error: *** BACKING UP: Station Name [192.168.x.x] *** FAILED: Station Name [192.168.x.x]: java.lang.NullPointerException Product Line TAC IA Series Environment I/A Series R2 UNC (Niagara) station Cause The error occurs because all available system threads are in use, preventing the backup operation from completing successfully. Resolution To resolve the issue: Increase Thread Count Open Admin Tool → Host → Edit File → System Properties. Increase the thread count from 15 to 30. Reboot the UNC After updating the thread count, restart the UNC to apply changes.

Issue When running the I/A Series R2 Niagara App Tunneling control panel applet on a Windows 7 computer, all display fields on the LON or Serial tunnel screen appear blank. If data is entered and the form is redisplayed, it comes up blank. Product Line TAC IA Series Environment Microsoft Windows 7 Professional operating system. I/A Series R2 Niagara Application Tunneling (serial and/or LON) Cause Insufficient Windows permissions prevent the tunneling configuration from being displayed or saved. Resolution There is no direct fix in the current version of the Niagara Application Tunneling client, but the following workaround resolves the issue: Open Windows Explorer and locate the file: C:\Windows\System32\natconfig.cpl Right-click the file and select Copy. Right-click on the desktop and select Paste Shortcut. Rename the shortcut to Niagara R2 Tunneling. Open Control Panel: If set to View by Category, change to Large Icons. Navigate to User Accounts → Change User Account Control settings. If the slider is at Always Notify or Default (second position), move it to the third position. Click OK to save. (Optional) Restore Control Panel view to Category. To run the applet: Right-click the shortcut and select Run as Administrator. The tunneling settings will now display correctly, and changes will be saved.

Issue In Niagara R2, IP communication to the UNC intermittently drops out without showing errors in the standard output window. Product Line TAC IA Series Environment Niagara R2 (all versions) UNC models: UNC-410, UNC-510, UNC-520 Cause Two or more UNC controllers are configured with the same IP address, creating a duplicate IP address conflict on the network. Resolution Verify the IP address configuration of all UNCs on the network. Assign a unique IP address to each UNC to eliminate duplication. Ensure no other devices on the network share the same IP address. After correcting the IP conflict, confirm stable communication with the UNC.

Issue When using BACnet Change of Value (COV) notifications in I/A Series R2, device objects learned as lite objects do not allow viewing or modifying the covIncrement property at the UNC. Product Line TAC IA Series Environment I/A Series R2 (Niagara) Cause BACnet lite objects are designed without the covIncrement property. If COV notifications are configured and adjustments to covIncrement are needed, changes must be made directly in the controller using WorkPlace Tech, followed by recompiling and downloading the application. Resolution To ensure the covIncrement property is accessible and editable from the UNC: In BACnet Service → BACnet Utilities, open the LearnDevice window. Uncheck the option Use lite objects before learning the device. This will create full BACnet objects, allowing the covIncrement property to be viewed and modified directly from the UNC.

Issue When attempting to open I/A Series R2 Workplace Pro or the Admin Tool, the program briefly displays its splash screen and then closes without any error message. Product Line TAC IA Series Environment I/A Series R2 WorkPlace Pro I/A Series R2 Admin tool Cause Insufficient computer memory prevents the standard 1024 MB Java heap from being reserved. Resolution Adjust the Java heap settings in the nre.properties file: Backup the file before making changes. Navigate to: \niagara\nre\lib Open nre.properties using a text editor (e.g., Notepad). Modify the line: java.options=-Xmx1024MB to: java.options=-Xmx768MB Leave all other parameters unchanged. Save the file and restart the software.

Issue Need to import data from a facility management system’s SQL database into an I/A Series R2 station. Product Line TAC IA Series Environment I/A Series R2 system External SQL database Cause The system requires integration of external SQL data for reporting or operational purposes. Resolution Use the sqlUtility module, which includes an object called SqlData to perform SQL queries on any SQL database. Important: The sqlUtility can only be used in an Enterprise Server, not in a UNC. Steps: Create a SQL query that returns a single column from the target data table. Example query: SELECT EnergyIntensity FROM EnergyTable ORDER BY O_Id DESC This query retrieves the EnergyIntensity column from the EnergyTable, sorted by record number (O_Id) in descending order. The returned value will be the first element in the first column of the query results, ensuring the newest value is obtained.

Issue Various errors appear in the Standard Output Window when attempting to edit a UNC station database using WorkPlace Pro (WPP). Errors include missing modules and out-of-date modules. Product Line TAC IA Series Environment I/A Series R2 WPP and UNC. Cause The engineer’s WPP installation does not match the UNC station configuration. Some modules in WPP are missing or at different revision levels. The NiagaraD service version on the engineer’s computer does not match the version installed on the UNC. Resolution Verify that all modules used in the UNC are present and match the versions in the nre\modules folder of the WPP system. Ensure the NiagaraD service running on the computer matches the software version installed on the UNC. If discrepancies exist, update WPP and modules to align with the UNC station configuration.

Issue When attempting to start a new I/A Series R2 Enterprise Server, the following error occurs: Cannot find distribution platform Product Line TAC IA Series Environment I/A Series R2 Enterprise Server WorkPlace Pro Cause The Enterprise Server software was installed without selecting the Program Files checkbox in the Select Modules dialog during installation.
