Issue Unable to connect to a G3 ENC or JACE after attempting to downgrade or install a station. One of several different errors may be displayed in the serial shell console output.  The following are examples: Could not find library libcpp.so.3 Could not find library libcpp.so.4 Error occurred during initialization of VM - Java/Lang/ No Class Def found error: Java/Lang/object Product Line TAC I/A Series Environment I/A Series G3 ENC and JACE (all revisions), ENC-410, ENC-520, TRD-T-645, TRD-T-603, TRD-RB-645, TRD-RB-603, TRD-J-600E, TRD-T-700 Cause The issue is caused by downgrading the ENC / JACE without following the procedure to first install the clean distribution file. In addition, the ENC/JACE will fail if a station is copied into the ENC/JACE without first installing the OS and NRE software using the Workbench Commissioning Wizard. Note: With G3 release 3.3 and newer, the procedure for downgrading an ENC/JACE is included in the Niagara AX Platform Guide - Downgrading a JACE (Clean Dist). Resolution Tools needed: Null Modem Cable Serial Terminal (e.g. HyperTerminal or TeraTerm) Jumper Obtaining the files required to recover the ENC NOTE: If recovery of a Jace-700 is required, please contact Product Support for the recovery file. Download the appropriate OS image and gz file zip file for the ENC/JACE from the Exchange website - https://ecobuilding.schneider-electric.com ENC-410.zip ENC-410-1 standard memory - etfs512 ENC-410-EM.zip ENC-410-1 extended memory - etfs2048 ENC-520.zip ENC-520-2 standard memory - etfs512 ENC-520-EM.zip ENC-520-2 extended memory - etfs2048 NPM6E.zip JACE603/645, TRD-RB-603/645, JACE600E Note: The files used in the following procedure MUST correctly match the ENC/JACE hardware platform, otherwise permanent damage to the unit may occur. The serial shell can be used to determine the file system requirements (standard or extended memory). To find the exact image needed for an ENC (JACE 2/4/5) execute the following while connected to the unit with serial shell: Log into the unit's menu system using the platform username and password. Type sh to exit the menu system and enter the shell mode. At the # prompt, (type: cat sys/info/fs) and enter This will return the file system type of etfs512 or etfs2048. Extract the OS image and gz files from the downloaded zip to a suitable directory on the local computer (e.g. local hard drive such as: c:\temp). Enable ftp: By default, the ftp port is disabled on every ENC/JACE as shipped from the factory.  Enable the ftp as follows. Set the jumper on the ENC to serial shell mode and connect the null modem cable between the PC and the ENC/JACE. Connect to the ENC using the Serial Terminal program and the following port settings: Baud rate 57600 bps (Note: JACE-603/645 baud rate is 115200) 8 data bits, 1 stop bit, no parity After logging in to the menu system from the serial shell, do the following to enable ftp: Select option 4 from the menu Enter the port number (Normally 21). (type: 21) Press the Enter key to confirm the change Note: Leave the serial shell connection open while performing the next steps. FTP the OS image and gz files On the local system, open a command prompt window and change the directory to the location where the OS image and gz files were extracted (c:\temp). Connect to the ENC via ftp and put the OS image in the /tmp directory entering the following from the command line: Create a ftp connection to the ENC by typing: ftp and enter Type the username and password for the platform when prompted Change directory to /tmp (type: cd tmp) and enter Change to binary mode (type: bin) and enter Download the image to the ENC by using the put command. The image name must exactly match the image extracted from the downloaded zip file. ENC-410-1 standard memory (type: put york-etfs512.image) and enter ENC-410-1 extended memory (type: put york-etfs2048.image) and enter ENC-520-1 standard memory (type: put james-etfs512.image) and enter ENC-520-1 extended memory (type: put james-etfs2048.image) and enter JACE-600E, 603, 645 extended memory (type: put npm6xx-etfs2048.image) and enter Download the gz file to the ENC by using the put command. The name must exactly match the image extracted from the downloaded zip file. Change directory to the root (type: cd ../..) and enter Change directory to /ffs0/zip (type: cd ffs0/zip) and enter Download the gz file (type: put clean.tar.gz) and enter Exit ftp (type: quit) and enter Execute OS image update Return to the serial shell connection Type sh to exit the menu system and enter the shell mode At the # prompt, type: osupdate and enter After a short delay the # prompt will return. Shutdown to reboot the ENC (type: shutdown) and press enter. The ENC/JACE will reboot, install the clean distribution image and perform one additional reboot automatically. The ENC/JACE should now be recovered and allow connection to the platform. Connect and use the Workbench Commissioning Wizard to install the version of G3 required.

Resolution There are two methods. Using Workplace Pro, Open a station (Note:  the station must be running)  Highlight the station name Select Search > Resource Count in the drop-down menu bar (alt-R shortcut) Using a web browser, In the address bar, type http://[stationHost]/prism/resources. Sign into the station using an Admin user account. This will display a summary at any level of the database. For each level there is a "Total objects" listing at the top of the page. This is where the resource count is displayed for that level.

Issue "Access Denied" errors are reported during the re-installation of the Niagara R2 software. Environment Niagara R2 software Cause The files installed in the nre\modules folder are write protected. Resolution If an attempt is made to reinstall Niagara R2 software on a computer, an installation error frequently occurs. The Niagara installer (second installation program) progresses one tick on the progress bar then displays a "Module Install Error" window containing the message "Access is Denied". Clicking the OK button to acknowledge the error results in the message window reappearing multiple times. This occurs because the files installed in the nre\modules folder are write protected when installed. To prevent this problem before attempting to reinstall any release of the Niagara R2 software, Open Windows Explorer ("My Computer") Select all files in the niagara\nre\modules folder Right-click on the selected files Select "properties" from the displayed menu. The Properties window appears.  Clear the mark in the "Read-only" box Click the OK button.

Issue Is there a way to backup a Niagara R2 UNC or Enterprise Server station from a web browser? Environment Niagara R2 UNC Enterprise Server XML-capable browser (IE 4.x or higher) Cause Need to save the station's database on the PC for possible restoration. Resolution Yes but note that this method will only backup the station database.  It will open the entire station database in XML format on the webpage.  Depending on the size of the station it may take a long time.  It is best to use this method if Workplace Pro is not available. Follow the steps below to create a station backup of a UNC or Enterprise Server via a web browser: Log into the station via a web browser Navigate to the following URL:  http://[ip-address]/prism/backup. Watch the lower left hand corner of the web browser.  The web pager loader indicator must finish. Once the web page indicates that it is done, save the page as a XML file to your PC.  Use the “Save As” choice to do this step. For more information review Appendix B of the Niagara Browser Access Guide.

Issue Settings for the USRobotics 5686 series for use with a DMS panel. Environment USRobotics 5686 series DMS panel Cause For the modems to communicate, V.92 protocol needs to be disabled. Resolution The V.92 protocol must be disabled when using these modems with older modems. To disable the V.92 protocol on a USRobotics 5686 series modems, enter the following setup string (without the quotation marks), in addition to any string specified in the referenced bulletin, before saving the settings: " AT +PIG=1 +PMH=1 +PQC=3 ".

Issue Can the existing communication wiring from a NETWORK 8000 (ASD) or DMS (Microsmart) project be re-used for a BACnet MS/TP trunk? Environment NETWORK 8000 (ASD) cable DMS (MicroSmart) cable BACnet MS/TP Cause Using ASD cable become an issue as baud rates increases pass the range of 9600 or 19.2 k. Resolution Testing has shown that existing communication wiring of a NETWORK 8000 (ASD)or DMS (MicroSmart) system is compatible at a speed setting of 9600 baud.  It is unlikely that this wire will work at higher baud rates or at extended distances.  Communications will be limited to the slower baud rates (9600 or 19200 baud) on these systems.

Issue Can third party BACnet/MSTP devices be placed on the same MSTP bus with MNB controllers? Environment MNB controllers MSTP communication bus Third-party BACnet/MSTP devices Cause Have not test MNB controllers and third-party BACnet/MSTP devices on the same BACnet MSTP communication Bus. Resolution There has not been thorough evaluation to know if third party devices can co-exist with MNB controllers. It is not currently recommended by the factory. The best solution is to create a separate BACnet network under a UNC/ENC to support the third party devices.

Issue A LON SNVT on a shadow object in a Niagara R2 UNC station takes 2-3 minutes to update after an override command is issued from a graphic. Environment Niagara R2 UNC LON SNVT on a shadow object Cause Minimum and maximum send times are not set correctly. Resolution Verify the maxSendtime and minSendtime parameters in the Local Lon Device > Config tab have the appropriate values (default values are 100 and 5 seconds respectively).   The minSendtime parameter specifies the minimum amount of time that the controller will wait before updating values. Re-upload the affected LON object from the LON controller. Re-bind the Lon object in the Lon Link Manager.

Issue The Mail Service in a Niagara R2 UNC station is configured correctly.  However, e-mails do not get sent to the SMTP server. Product Line TAC IA Series Environment Niagara R2 UNC station Cause The Niagara station needs to enable mail.smtp.auth in system.properties. Resolution In the station, the following lines need to be added to the system.properties file if authentication is required: mail.smtp.auth=true mail.useUTF=false Once these lines are added and the UNC is re-booted, the UNC will successfully send emails to the SMTP server.

Issue A Binary Output object has just been created in a Niagara R2 UNC station.  The Prioritized Output of the object defaults to a state of "Active" at a priority 10. Environment Niagara R2 UNC Cause It can be a corruption issue with the station database. Resolution Re-load the UNC station database from Workplace Pro (convert the .db file to .sns in the Admin Tool) to resolve the issue.

Resolution In Workplace Pro, Right-click the Database Service in the station, click Go then Properties In the General > Status tab, the databaseProductVersion field will have the Cloudscape version.

Issue Why is the BACnet/MSTP controller MAC address displaying an incorrect value in Workplace Pro? Environment BACnet/MSTP Controller Workplace Pro Cause MAC address on MSTP used number from 1 to 253 Resolution In the Niagara BACnet Integration guide (page 3-8), the MSTP MAC address is expressed as a number from 1-253. Upon entering a number larger than 99, this field will cut off the hundreds digit and keep the remaining two digits. The remaining value will also be expressed in hexadecimal. A decimal 253 would display as hexadecimal 53. To correctly populate this field enter the MSTP MAC address in hexadecimal.

Issue Is there a limit to the number of BACnet objects programmed into a MNB controller? Environment MNB Cause There are two limits to keep in mind.   Resolution The first limit is the memory range of the controller.  Each object type has a specific memory size that it consumes when it is loaded in a controller. The WorkPlace Tech Tool 5.x Engineering Guide Supplement provides memory ranges for each BACnet object. The second thing to consider is the BACnet Instance Number ranges available to each type of object. MNB controllers have a fixed number of available Instance Numbers for each object type.   Refer to the Workplace Tech Tool 5.x Engineering Guide Supplement for each of these ranges.
