Issue What is the preferred method of finding the MAC address of a Niagara R2 UNC? Environment Niagara R2 UNC Cause Determine the MAC address to set up the reserved IP address. Resolution The quickest and easiest method of finding the MAC address of a UNC is by way of the following: From a command window, ping the UNC using the following command: ping IP , where IP Address is the Internet Protocol Address of the known UNC.  After receiving the Ping Statistics, type the following command: arp -a The physical address will then be shown. *NOTE: All UNCs will have the following generic first four octets: 00-20-96-05. The last two octets will be specific to the Serial Number of the UNC.

Issue In Niagara G3, is there a way to access the Alarm Portal through a web browser? Environment Niagara G3 Alarm Portal Cause Through the web, only the alarm console associated with the connected station can be viewed, and only one station at a time. Resolution The Alarm Portal is a program that runs off the Workbench framework, but can also be purchased as a stand alone product (i.e. no need to purchase Workbench and Alarm Portal, just purchase the portal). With the Alarm Portal software, connecting to multiple consoles at once is possible (similar to using Tools > Alarm Portal within Workbench). The other option is to create a Station Recipient for the desired alarm class in the ENC station's Alarm Service that points to the Enterprise Network Server, and use the server's Alarm Console. As long as the user has permissions to access the alarm console in the server, then the user can navigate to it in the nav tree.  It can also be added as a node in the .nav file for easy access to the location.  The user would still need the appropriate permissions to access the console.

Issue Which antivirus software is compatible with Niagara R2 and G3? Environment Niagara R2 Workplace Pro (all versions), Niagara G3 Workbench (all versions) Cause Antivirus software can block ports and services used by Niagara R2 and G3 Resolution By default, Niagara R2 software needs the following ports/services/applications "open", or unblocked: Port 80 (station communications & Web access) Port 3011 (Admin Tool) Niagara Service (Control Panel > Administrative Tools > Services) Files in the C:\ < niagara r2 release number > \nre\bin directory By default, Niagara G3 software needs the following ports/services/applications "open", or unblocked: Port 80 (Web access) Port 1911 (station communications) Port 3011 (Platform access) Niagara Service (Control Panel > Administrative Tools > Services) Files in the C:\ < niagara g3 release number > \bin directory Various antivirus software products by default will block one or more of the above, and need to be configured to allow or "unblock" them.  Niagara R2 and G3 software will work with any antivirus program that allows unblocked communication to the above ports, services, and files.   NOTE: The specified ethernet ports must be open bidirectionally for both TCP and UDP traffic.

Issue In a Niagara R2 UNC-600 (or UNC-610), when using the Installation Wizard to review installed jar files, this error appears: "Cannot find distribution set platform matching the target installation platform (NT)" Environment Niagara R2 UNC-600 (or UNC-610) Installation Wizard Cause The UNC-600 and UNC-610 use jar files stored in the "nt" directory. This error appears if the "emb" directory is selected instead. Resolution The "emb" directory is used for embedded UNCs like the UNC-410 and UNC-5x0. Selecting the "nt" directory will prevent the error from appearing and allow continuation to the jar file summary review window.

Issue How can it be determined if a new Niagara G3 ENC or new Niagara R2 UNC has the new boot flash? Environment Niagara G3 ENC Niagara R2 UNC Cause Determine boot flash version. Resolution The best way to determine if the controller has the new or old boot flash is to compare the serial number on the printed circuit board with the numbers listed below: UNC New Boot Flash (requires 529) UNC-410:Serial number 36218 or greater, shipped 6/16/10 UNC-520:Serial number 36184 or greater, shipped 6/16/10 ENC New Boot Flash ENC-410:Serial number 263187 or greater, shipped 5/18/10 ENC-520:Serial number 263122 or greater, shipped 5/13/10 If the serial number was removed or is not legible, contact Product Support Services for assistance. There is additional information available that will assist in determining the new and old boot flash.

Issue In Niagara G3, how can an objects value be displayed in a graphic and not its status? Environment Niagara G3 Cause Default BoundLabel properties of the object are set to display the value and status. It must be adjusted to display only the value. Resolution In the BoundLabel properties of the object, the default text format is %.% This displays the value and the status of the object. To display just the object's value, edit the format to %out.value% The object will then display only the present value in the graphic.

Issue In Niagara G3, how can a Boolean object's "False" condition be made to disappear? Environment Niagara G3 Boolean Object Cause BoundLabel properties must be adjusted for the desired operation. Resolution In the BoundLabel properties of the object, right-click on the "visible" field, and choose "Animate" In the Animate window, click on the drop-down for the "Converter Type", and choose "I Boolean to Simple" Click the drop-down for the "False Value", and select "false" Click OK to close the Animate window Click OK to close the BoundLabel properties window Save the graphic Now, when the object has a value of "false," it will not be visible in the graphic.

Issue How many histories can be created in a station and how many records are allowed per history? Environment I/A Series G3 ENC, ENS or SoftJace CComTrolCCWEBor CES Cause Technical product information update. Resolution Regardless of platform type, histories are stored under the station's file system (file:^history/). Stations running on a PC-based system (Enterprise Server or SoftJACE) store the histories in subdirectories using segmented files; this provides improved search capabilities over a flat file system. Stations running on a QNX-based system (ENC) store all of the stations histories in a single compressed file (history.zip). A running station opens the history.zip file in the ENC's ram disk space, the histories are compressed and saved to flash whenever the station is saved. Opening the history.zip file to the ram disk eliminates the need to write to the flash drive each time a record is added to the history file.   When the station needs to write a record to a history, it opens the specific history into the running station (either from the file system if PC-based, or from the ram disk if QNX-based). The open history does contribute to the heap.used of the station. The history service has one property 'max open time' (default 5 minutes) which causes the station to close the history from the running station heap if no records have been written to the history for a time period exceeding the 'max open time'.   Each history extension which is added to the station does add slightly to the station resources because the extension is represented in the bog file. When the history is first enabled, the station creates the history file. The initial file includes a 1600 byte header (defines the configuration parameters) and a single page file of 4096 byte size. When triggered by either the collection interval or COV/COS, a record is added to the page file. When the page file becomes full, additional page files are created based on the capacity configuration of the history. History Record Size by Point Type Point Type bytes/record boolean 13 enum 16 single precision numeric 16 double precision numeric 20 string variable length * *NOTE: A single 'string' record cannot exceed one page (4096 bytes)   Since histories count as file descriptors, there is a physical limitation on the number of histories allowed in a QNX-based ENC station. It is recommended not to exceed 800 histories, given the file descriptor limit of 1000. Note: The platform services view of the QNX-based JACE station includes a property to modify the size of the ram disk within defined limitations. Note that the alarm database is also maintained in the same ram disk space. Exercise caution when modifying the default ram disk size; note that allocating additional memory to the ram disk will limit the memory available for other functions by the QNX OS. Reducing the ram disk size too much could result in history or alarm records not being stored properly and erratic station behavior.

Issue When attempting to run the WorkPlace Tech Tool, Application Menu missing or grayed out. All WorkPlace Tech Tool related entries in the Tools menu are grayed out or missing.   Project Toolbars are not displayed. "Unknown error occurred in an add-on to WorkPlace Tech" Environment WorkPlace Tech Tool 5.7.4 and later versions Microsoft  Visio 2003 or Visio 2007 Microsoft Windows XPsp2, XPsp3,  Vista or Windows 7 Cause Various causes beyond the scope of this article. Resolution There are several different reasons why these entries are grayed out or missing and therefore not selectable. The exact procedure for correcting the problem depends on the version of Visio and the version of Windows being used.

Issue WorkPlace Tech Tool 5.7.4 causes Visio to crash when attempting to open some MNL-800 applications.   The problem occurs with MNL-800 applications that were created with WorkPlace Tech version 4.x where the application does not use the hardware schedule function.  Environment WorkPlace Tech Tool version 5.7.4 MNL-800 application file created with WorkPlace Tech Tool version 4.x Hardware schedule has never been enabled using an earlier version of WorkPlace Tech Tool version 5.x Cause Required hardware tag "DayOfWk" missing (normally shown on left tag rail, if unused in the application). Resolution This problem is automatically repaired in WPT version 5.7.5 or newer. While we recommend upgrading WPT to 5.7.5 or newer, you can continue to run WPT 5.7.4 and  correct the problem by taking the file to a computer running WorkPlace Tech version 5.7.3 and following this procedure: Open the existing file in the existing project (or in a new project). Run the Hardware Wizard and click [Next] twice to display the Time & Schedule page. Check the box  "Enable the built-in schedule" then click [Finish] to update the application file with the schedule reference tags. Run the Hardware Wizard a second time and click [Next] twice to display the Time & Schedule page. Un-check the box "Enable the built-in schedule" then click [Finish] to update the application file removing the unused schedule reference tags. Close the application.  This will save the changes to the application file.  If prompted to convert the drawing, do not convert it. The saved application file will be usable in WorkPlace Tech Tool version 5.7.4

Issue The short cut created during the installation of DMS OPRIF 11.6 for DCT will not function. Environment DMS OPRIF 11.6 running in a Windows OS. Cause Unknown. Resolution To work around this issue, run the DCT.BAT located in the DCT folder.  The installed desktop short-cut should be modified by editing the installed short cut line “call c350dct” to “call dct.bat”. To improve system performance when running DCT modify the DCT.BAT file in the DCT folder from “dctgl.exe %1 %2” to “start /low dctgl.exe %1 %2”.

Issue DMS OPRIF 11.6 locks up when attempting to tunnel with Niagara R2 or Niagara G3. Environment OPRIF 11.6 with a Windows OS. Cause The file path becomes too long for the Windows OS. Resolution OPRIF 11.6 by default will install in to the following default directory (x = drive letter): x:\Documents and Settings\username\Local Settings\Temp.  To resolve the excessive path length, install OPRIF into the root folder (i.e. x:\  where "x" is the desired drive) on the computer. The path can be specified in the extraction screen provided during installation.

Issue An Internet Explorer ActiveX function involving the running of Java applets used to display the I/A Series R2 graphics prevents the Java applet from executing properly. Environment I/A Series R2 software release 522.v2, 529 or 532 Cause Microsoft changed the procedure by which Internet Explorer handles third party ActiveX applets, including the Java applets used in the I/A Series R2 system.  This change was applied as an update to all older versions of Internet Explorer and is included in Internet Explorer 8. Resolution There was a workaround provided with the R2 522.v2 release that can be used to prevent this Java applet activation issue from happening. The update consists of adding or modifying some of the information in the station.properties files and applies to both ES based stations and UNC based stations. 1. To update the Enterprise Server / WorkPlace Pro, save and backup the station database accordingly. While in the admin tool, open the station.properties file.  Select menu item Admin Tool -> Host -> Edit File -> System Properties.  Edit the file by adding the following text to the end of the file.   Make sure not to delete the # character as this specifies a comment line.  Save and close the system.properties file (File ->Save). # This is used to disable the IE ActiveX activation fix. If set to # to false, then the user will be required to click on the applet # before he is able to interact with it (only effects IE users). ie.activex.activation=false 2. To update the UNCs, log into the UNC using the Admin Tool and open the station.properties file.  Select menu item Admin Tool -> Host -> Edit File -> System Properties.  Edit the file by adding the following text to the end of the file. Make sure not to delete the # character as this specifies a comment line.  Save and close the system.properties file (File -> Save). # This is used to disable the IE ActiveX activation fix. If set to # to false, then the user will be required to click on the applet # before he is able to interact with it (only effects IE users). ie.activex.activation=false

Issue Changing the nci_PowerUpDly value in the MNL-800 has no effect.  With the nci_PowerUpDly set to 120 seconds in the MNL-800, the outputs turned on after 10 seconds, the default setting. Environment WorkPlace Tech, all versions. MNL-800 Cause The nciPowerUpDly provided in the MNL-800 does not function correctly. The design intent of the nci was to determine the time, in seconds, that must expire following a controller reset before the MN 800 hardware outputs (Digital Outputs and Analog Outputs) are activated. Resolution Be aware that the nciPowerUpDly in the MNL-800 does not work properly, and that the outputs are delayed approximately 10 seconds, regardless of the value entered for nciPowerUpDly.

Issue When attempting to open an I/A Series R2 graphics page, the desired page is not displayed.  A blank gray or white page or page with graphic size gray box may be displayed. Environment Niagara R2 software version 522v2, 529 or 532 installed on station being accessed. Microsoft Internet Explorer being used to access the web based graphic page. Cause A Microsoft Internet Explorer security update causes some Niagara R2 ActiveX objects to be improperly handled and therefore not displayed.  This same Internet Explorer security update is included in all newer versions (7  & 😎 of the Microsoft Internet Explorer browser. Resolution Open the I/A Series R2 station using the R2 Admin Tool. Open the "station.properties" file by selecting "Admin Tool" from the menu then selecting "Host" then "Edit File" then "System.Properties". Add the following four lines to the end of the file (do not delete the # symbol from the beginning of the lines): # This is used to disable the IE ActiveX activation fix. If set to # to false, then the user will be required to click on the applet # before he is able to interact with it (only effects IE users). ie.activex.activation=false   After adding the lines, select "Save" from the "File" menu to save the changes. Reboot or restart the station to allow the change to take effect.  

Issue The license form does not show support for the IA-DRV-MOD (Modbus) driver on a UNC-410. Environment I/A Series R2 UNC-410 Cause License request form for I/A series UNC-410 does not list IA-DRV-MOD as an available option The UNC-410 does not support any serial driver such as Modbus or ASD since it's serial ports are not electrically isolated. A UNC-410 will only allow integration to LON and/or BACnet IP or BACnet Ethernet. Resolution If integration to Modbus is required a UNC-520 should be selected rather than a UNC-410.

Issue I cannot find any published instructions giving the procedure to install an updated version of one of the JAR files on my I/A Series (Niagara) system. Product Line TAC IA Series Environment I/A Series (Niagara) R2 software (any version) installed on a Windows computer Cause An updated version of one of the JAR files installed in an I/A Series (Niagara) R2 system has been published.  The updated file has been downloaded to my computer but there are no instructions on how to install it. Resolution For the purpose of this explanation of the procedure, the following steps reference an update to the "programlib" jar file for release 2.301.522.   Substitute the name of the jar file being updated and release number in the following steps. * NOTE: Before attempting to update a jar file, verify that Windows Explorer is configured to display file type extensions. (See * below for more information). The JAR file update is published, currently on the  as a .zip file containing two files.  Copy the file programLib-2.301.522c.v1.jar.emb to the \niagara\r2.301.522\emb folder. Rename the existing file  from programLib-2.301.522.v1.jar to programLib-2.301.522.v1.jar.old. Rename new file from programLib-2.301.522c.v1.jar.emb to programLib-2.301.522c.v1.jar (removing the .emb extension). Copy the file programLib-2.301.522.v1.jar.nt to the \niagara\r2.301.522\nt folder. Rename the existing file  from programLib-2.301.522.v1.jar to programLib-2.301.522.v1.jar.old. Rename new file from programLib-2.301.522c.v1.jar.nt to programLib-2.301.522c.v1.jar (removing the .nt extension). Copy the file programLib-2.301.522.v1.jar.nt  to the \niagara\r2.301.522\nre\modules folder Rename the existing file  from programLib-2.301.522.v1.jar to programLib-2.301.522.v1.jar.old. Rename new file from programLib-2.301.522c.v1.jar.emb to programLib-2.301.522c.v1.jar (removing the .nt extension). To install the new jar file into a UNC, perform the following procedure after completing steps 1 through 9, above. Start the Niagara 522 version of the Admin Tool. Open a connection to the UNC Select the "Installation" tab then click the [Installation Wizard] button. Select the "emb" folder in the "Select Distribution Directory" window then click [Install] In the "Niagara Remote Installation" window, select the "Configure Modules Only" radio button then click the [Next >] button. Verify that there is a checkmark in the "Upgrade/Add" column for the updated jar file. Click the [Next >] button to continue. Make sure that on the "Database Backup" screen that you do backup the existing database. Continue through the remaining steps and allow the upgrade to install and the station to restart.   * To properly rename the files as described in this procedure, Windows Explorer must be configured to show file type extensions.  To configure this setting or verify it, proceed as follows: Open Windows Explorer by clicking on the My Computer (or Computer) icon on the computer's desktop or by making the selection from the Windows start menu. From the Windows Explorer "Tools" menu, select "Folder Options" Select the "View" tab. Scroll down through the "Advanced Settings" list to locate the entry "Hide extensions for know file types".  Verify that this entry is unchecked. Click the [OK] button to save the change, if any, and exit the Folder Options screen.

Issue When polling BACnet points with an I/A Series R2 (Niagara) UNC, a warning frequently appears in the Standard Output Window that reads "Warning: BACnet Read Property Multiple Error" followed by a property name and device or object name. Environment I/A Series R2 (Niagara) UNC or BACnet Server Cause The warning is reported when a UNC or BACnet Server station polls a BACnet device, and that BACnet device does not support the Read Property Multiple" function.  All data will be retrieved because the station will detect the warning and will poll each requested property, one property at a time. Resolution This is not an issue, just normal operation.  The startup warning messages could be suppressed by setting the device's Read Property Multiple property to false.  However, disabling read property multiple will slow the polling of this device. 

Issue Changing between view and edit modes using Workbench after adding a PxInclude object to a parent px file with a schedule causes Workbench to lockup and fail. A restart of the Workbench application is required. Environment TAC I/A Series G3 ENC-410, ENC-520, and Enterprise Network Server Cause Workbench failed to process the scheduler within the PxInclude. Resolution The issue has been resolved in bajaUi module versions 3.3.34.2, 3.4.64.1, 3.5.34.1 and higher.  The files, bajaui 3.3.34.2 is available for download from The Exchange Download Center.  Download the bajaUi version zip file for the required G3 build. Caution: Always backup the station database before performing any upgrade.   If Enterprise Network Server, stop running station and close the Workbench application.  Extract the file and replace the existing bajaUi jar file in the appropriate modules directory of G3. Start Workbench and start station if Enterprise Network Server. Use the Workbench Platform Software Manager to the upgrade the bajaUi module in ENCs as required.
