Once assigned right click on the controller select MNL and select Download application.

Issue Site has no server, just a single stand-alone jace.  It has histories.  How can the data be exported? Environment Niagara G3 / AX any jace model running version 3.x Cause Viewing historical data without the benefits of an Enterprise Server Resolution Do a manual export from the 'History Table' view: Expand the history space in the tree. Select the history to export. Right click and select View-> 'History Table'. Look over on the upper right corner of the history table. There is the tiny icon that looks kind of like a table with a little upside down triangle. Click that. Select Export. Then select the exporter in the drop down -  HistoryTable to CSV. Select 'Save to File' and then browse to a folder and enter a desired file name. Press OK.

Issue Customer site is currently installed with Niagara R2.  A defective UNC has been replaced with the hybrid jace (-603 or -645) and is running the Niagara R2 station from the UNC. In the future, if the customer converts the building to Niagara G3 / AX, what has to be done to the jace to convert it from R2 to G3? Environment Niagara R2 Niagara G3 / AX jace-603 jace-645 Cause Future considerations Resolution If the site upgrades to Niagara G3 / AX, the customer orders part # TRD-G3-6XX for the hybrid jace. This will transfer the R2 license to the G3 environment. It will include any optional drivers (like Modbus) as well as Schneider-Electric proprietary drivers (like ibsASD).  Physically, the board remains as is.

Issue WorkPlace Commissioning Tool configured for BACnet IP is unable to discover MNB MS/TP devices connected to an ENC Environment I/A Series G3 Enterprise Network Controller BACnet Integration Cause The ENC station's BACnet routing is not enabled.

Issue One folder, on a jobsite computer, contains all the DMS backups done over the past several years.  Since each backup contains multiple files, how can the files be identified and then grouped together for easy retrieval in the future? Environment DMS35, DMS350A, and DMS3500 (revisions 9, 10, and 11) Cause Multiple DMS backups were performed from the same jobsite computer. They were not grouped by name or date. All the backup files exist in one folder in a disorganized state. Resolution The files created from a database 'save' for a DMS35 or DMS3500 are: filename.IOC (stores DMS point IDs, records, alarm parameters) filename.UC (stores DMS point configuration elements) filename.PG (stores DMS tables and schedules) filename.UDP (stores UDPs in the DMS panel) The files created from a database 'save' for a DMS350A include the four listed above as well as: filename.Dxx (stores DCM tables, schedules, and other elements) filename.Uxx (stores DCM UDPs) where xx = DCM address 01-32

Issue The hostId for a computer running I/A Series G3 version 3.8u1 (or earlier) and N4 versions 4.2 (or earlier) may be changed from the result of a Windows update. Product Line TAC IA Series Environment I/A Series G3  I/A Series N4  Cause The hostId is automatically generated upon first install of the software and stored within the registry.  The location of the G3 versions 3.8u1 or (earlier) and N4 versions 4.2 or (earlier) registry keys can be affected by a Windows update. the G3 versions 3.8u1 or (earlier) and N4 versions 4.2 or (earlier) registry keys can be affected by a Windows update.The hostId is automatically generated upon first install of the software and stored within the registry.  The location of    the G3 versions 3.8u1 or (earlier) and N4 versions 4.2 or (earlier) registry keys can be affected by a Windows update. Resolution I/A Series G3 version 3.8.213 (or higher) and I/A Series N4 version 4.3.58.18 (or higher) have been modified to guard against Windows updates to prevent hostId changes.  Installations of N4 4.3 and/or G3 3.8u2 will continue to operate normally and will not assume a new hostid after a Windows update.  All previous versions of Niagara could generate a new hostid after a Windows update, requiring a license replacement.   Schneider Electric recommends updating I/A Series G3 and N4 installations to the latest released software in order to maintain the latest security protection and to gain benefit from the latest features.  These builds are:   I/A Series 3.8 Update 2 (3.8.213 and later) I/A Series 4.4 (and later)   Patch to address multiple Host IDs on a single Microsoft Windows© platform   A set of patch files have been created to stabilize the Host ID for cases where customers have not upgraded to the latest version of Niagara (see installation instructions below). Once these patches are applied to the older versions of Workbench the Host ID is stabilized and should not change if Windows updates are installed.   Note: This is a reminder that a 32-bit install will always generate a different host-id than a 64-bit install.   IMPORTANT NOTES REGARDING THE PATCHES   Patches are only supported for the latest update (maintenance) version for the relevant release. Patches are not available for I/A Series G3 release 3.5 and earlier, or I/A Series N4 release 4.0 or 4.1. Builds prior to G3 3.8.213 are considered unsupported. Customers applying these patches do so at their own risk. Newer versions of Niagara (3.8U2 and 4.3) have introduced a stabilized method of managing the Host ID and do not require any patch. The patches do not eliminate the issue of different Host IDs generated when installing 32-bit and 64-bit Niagara. Installation Instructions   The Host ID patch file is available for download on the EcoBuilding Exchange Download website.  Login to the Schneider Electric EcoBuilding Exchange Download Center and enter G3 and N4 Host ID Patches in the search area or the filename of the zip shown below.    Download the G3_N4_HOSTID_PATCHES.zip and unzip into a temporary folder. The archive contains 'nre.dll' for various versions of I/A Series G3 and Series 4.2 in a directory structure identifying them first by version and sub-directory identifying 64-bit or 32-bit Windows. The 4.2 folder also contains 'njre.dll' which will need to be copied only for 4.2 installations.  Follow these instructions:   Verify the installed java version to be either 64-bit or 32-bit. Start a Niagara Command Line (Home>/bin/console.exe) from the desktop of the platform to be patched. From the Niagara Command Line execute the command: nre -version One of the listed items will be java.vm.name. If the text contains “64-Bit” then the installation is 64-bit otherwise the installation is 32-bit. Stop any running station using Workbench's Platform Application Director on the platform to be patched. Exit Workbench if running on the platform to be patched. From the Niagara Command Line ... /bin/console.exe execute the command: plat uninstalldaemon  Prior to replacement, save a copy of the existing nre.dll located in /bin folder. If Niagara 4.2 is being updated also save a copy of the existing njre.dll located in /bin folder. Copy the version appropriate and OS appropriate (64-bit or 32-bit) downloaded version of nre.dll file to the Home>/bin folder. If Niagara 4.2 also copy njre.dll to /bin folder. Overwrite the existing file(s). From the Niagara Command Line (/bin/console.exe) execute: plat installdaemon Start Workbench.  Open a platform connection to the patched platform. Using the Application Director, start the station.

Issue Using the TAC I/A BACnet WorkPlace Balance Tool to balance a VAV, when requesting the box drive to Maximum flow, get error "Controller was temporarily busy. Please restart this balancing step” message. What does this mean and how to solve it? Environment BACnet  WorkPlace Flow Balance Tool MNB-V1 MNB-V2 Cause Multiple tools connected to the same VAV controller.  Resolution "Controller was temporarily busy. Please restart this balancing step” message means one of two things – One tool has control of the VAV while another is attempting to connect or the VAV is in the process of completing a balancing step while another balancing function is attempted. Flow balancing should be  accomplished with a single tool connected to a VAV controller.  

Issue Can an existing UNC-600 serve graphics for a new UNC-520, without adding an Enterprise Server? Environment I/A Series (Niagara) UNC-600 I/A Series (Niagara) UNC-520 Cause Application for serving graphics without adding Enterprise Server. Resolution Yes you can without adding a Enterprise Server. It is recommended that native Niagara objects in the UNC-600 be liked to data points in the UNC-520. This will optimize communication speed and database modifications if need. Remember to set-up the address book and select PEER to PEER. And to watch the resource count of the UNC-600

Issue How to identify the DMS (MicroSmart) MSC-P1502 Enhanced from the non- Enhanced version. Environment DMS MicroSmart MSC-P1500 series Cause Controller version identification Resolution The MSC-P1502 controller came in two versions, non-Enhanced and Enhanced. The Enhanced version had the feature for AI 5 & 6 to be configured (jumpers J1 & J2) for a Voltage/mA input or resistance input.  Non-Enhanced version: Using OPRIF to communicate to the controller, the controller greeting screen would display PCB as the Controller Type. Visual identification would be that the circuit board has a label with the p/n MSCA-6160.  Enhanced version: : Using OPRIF to communicate to the controller, the controller greeting screen would display PCB as the Controller Type.  Visual identification would be that the circuit board has a label with the p/n MSCA-6161.  If there is no p/n label on the board, another way to identify an enhanced version is by looking at the circuit board. Above the inputs AI5 & AI6 there would be a white box with the wording ENHANCED AI.
