Resolution Re-install Niagara and verify the path for installation is correct.  If this does not correct the issue, manually copy all files from the I/A Series G3 installation CD module folder into the appropriate modules folder on the target computer.

Issue Wants to run old UNC-600 station as an enterprise server but the license does not include LON.  How do you order it? Environment I/A Series R2 Enterprise Server I/A Series SoftJace Cause Customer wants to migrate a UNC-600 station to an enterprise server.  The UNC-600 was already providing the needed database services so the station cannot be directly moved to a UNC.  Even without the database service, the station may be too large for one UNC-520. Resolution Tridium does not make the LonWorks license available for the Enterprise Server or for the SoftJace.

Issue I/A Series G3 Enterprise Network Server (ENS) learned proxy point does not properly inherit the maximum override duration facet setting configured point or points at the ENC.  Environment I/A Series G3 versions 3.5.xx and earlier Cause The mechanism within the core G3 software that controls the inheritance of the maxOverrideDuration facet for a learned proxy point was not added until 3.6.31. Resolution Upgrade the I/A Series G3 Enterprise Network Server (ENS) and ENC to version 3.6.31 or higher.

Issue What hardware platform can be used to replace the I/A Series R2 UNC-600 or UNC-610? Product Line TAC IA Series Environment I/A Series R2 UNC-600 UNC-610 Cause The I/A Series R2 UNC-600 and UNC-610 are obsolete and can no longer be repaired. Resolution The JACE-NXT (TRD-NXT-R2) can be considered the replacement for a UNC-6xx. The JACE-NXT includes (2) 10/100 Mb Ethernet ports and (1) RS-232 port, one isolated RS-485 port, one FTT-10A LonWorks interface, four USB ports, a 250 GB hard drive and includes a Windows XP Embedded operating system. Similar to the UNC-610 the JACE-NXT supports LonWorks and BACnet Ethernet / BACnet IP. Legacy driver support includes GCM, ASD, and DMS. Note: The JACE-NXT will not directly support BACnet MSTP or MicroSmart devices. The JACE-NXT requires installation of R2 Release 2.301.532 or higher. TRD-NXT-UI (Web Browser Support) TRD-NXT-UPS (Optional UPS - includes UPS unit and battery)

Issue TreeTech 3.1 is installed on a Windows 7-32 bit computer.  After receiving the unlock code and entering it, a pop-up error window appears stating "Cannot Access Registry". Environment TreeTech 3.1 Windows 7-32 bit Cause The Windows user account was not configured for a password. Resolution Modify the Windows user account to ensure it has administrative rights and that it has a non-blank password.

Issue Installing an updated I/A Series G3 license does not enable options updated in the new license. Environment I/A Series G3 Workbench or G3 Enterprise Network Server (all versions) Cause When installing a new I/A Series G3 license, it may be necessary to restart the NiagaraD service before the updates contained in the license take effect.  This issue is most often noticed when a demo license update is installed after the previous demo license has expired. Resolution After installing an upgraded license, regardless of whether the license was installed automatically from the license server or manually, stop and restart the NiagaraD service.  The NiagaraD service can be restarted either from the Windows Services control panel applet or by using the Install Niagara Platform Daemon.

Issue I/A Series R2 Soft JACE - Unable to select and define as a Soft JACE during the installation process on a Windows 7 32-bit operating system. Environment I/A Series R2 Soft JACE (build 529 or higher) Cause The I/A Series R2 installation utility does not recognize the Windows 7 operating system as a platform for the Soft JACE and bypasses the associated Soft JACE selection screen. The software is properly installed, however the licensing mechanism is unable to use the R2 Soft JACE dongle. Resolution Continue the installation of the I/A Series R2 software (as would be similar to installing the R2 Enterprise Server). Upon start, the software will generate a standard host ID (xxxx-xxxx).  Note: The I/A Series R2 Soft JACE license dongle will not be used. Fill out the associated I/A Series R2 Soft JACE license form with the new host ID and jobsite information. Forms can be found on both the iPortal and The Exchange Download Center websites. iPortal https://iportal2.schneider-electric.com  - Login and navigate to Tools & Support > Tools and select Manage Forms.

Refer to PA-00458 I/A Series R2 Licensing. 

Issue Needs to add two MNB-300 controllers under an ENC-410.  How do I order the license? Environment ENC-410 Cause Needs to add some MNB-300 controllers under an existing ENC-410. Resolution According to our published literature, the ENC-410 does not support BACnet MS/TP because the RS-485 port is not isolated. If it becomes absolutely necessary to license an ENC-410 for BACnet MS/TP, you must submit a written or emailed request to the I/A Series G3 product marketing manager.  The product marketing manager may approve or deny the request based on the information contained in your request.  If approved, he will provide ordering and pricing information.

Issue Getting the error “Class not found exception: com.microsoft.sqlserver:jdbt.sqlserverdriver” when attempting the convert a Cloudscape database to SQL 2005 in the Niagara R2 console window. Environment Niagara R2, WorkPlace Pro version 529 and higher, Windows SQL 2005 Cause The wrong command was entered in the Niagara Command Line window (the console). The following was entered at the prompt: “dbadmin station_name m cs ms host_IP:TCP_port username password”. The “ms” portion of the command is used with SQL versions prior to SQL 2005. The “ms” portion of the command line should read “msj”, which SQL 2005 requires. Resolution Open the console and re-enter the correct migration command. 1. Open the console window 2. Type the following in the Command Line: dbadmin "station_name" m cs msj host_IP:TCP_port# username password 3. Enter The database migration should be displayed in the console window.

The Enterprise Server and SQL 2005 database names have to be the same when migrating the Cloudscape database to a SQL 2005 database. Resolution Rename either the Enterprise Server station or SQL Server database so that the names are the same. Once the names are the same, the migration should go without issues.

Issue Does TreeTech version 3.1 & 3.2 support all block types in all types of GCMs and LCMs? Product Line TAC IA Series Environment TreeTech version 3.1 or 3.2 GCM-84xxx GCM-86xxx SIM-xxxxx LNC GIM-2100 LCM-8xxxx Cause Block types supported are not listed in the Tree-Tech Engineering Guide document, F-26640 Resolution The following table lists the sub-devices supported by TreeTech 3.1 or 3.2 for each Network 8000 device type.

Issue Is there a way to output the average of logged values contained within the I/A Series G3 history records? Environment I/A Series G3 Cause I/A Series G3 history tables contain records of values logged by the associated trend objects.  A BQL query must be used to read records from the table and perform a calculation to average the values. Resolution A program object that contains a BQL query can be used to read the records from a history table and calculate minimum, maximum, average, etc. The AX community module contains a BQL object (Trend Dynamic Analyzer) that can be assigned to a history ord and configured to a particular timeframe. A new trend with a specific number of records (rolling) can be queried by this object which in turn calculates the Count, Min, Max, Average, and Sum. The axCommunity module contains a library of useful objects for the Tridium Niagara AX platform created by AX programmers.  Download the axCommunity module from the following website - http://sourceforge.net/projects/niagaraaxcommun/. Note: Schneider Electric does not maintain and is not responsible for the content within the axCommunity module. The user should test and utilize at their discretion and risk. Copy the axCommunity.jar file into the Workbench platform (modules folder).  Install into the target platform as needed. Open the axCommunity palette and add a TrendDynamicAnalyzer object into the station. View the TrendDynamicAnalyzer property sheet and then assign the History using the History Ord Chooser. Connect an Interval Trigger if a time based refresh of the values is required. You may want to limit the values at the output if the values trended by the history can get out of range (e.g. initialization, etc.).

Issue The web service within the ENC-520 indicates a status fault - Unlicensed:javax.baja.license.FeatureNotLicensedException. Environment I/A Series G3, ENC-410, ENC-520 Cause The web service has been added to the station however the ENC-520 is not licensed to support the web services.  The web services status will indicate the fault condition and the ENC will not serve up graphics. Resolution Requires purchase of the web services option for the appropriate platform. ENC-410-1 >> purchase ENC-410-WEB ENC-520-2 >> purchase ENC-510-WEB

Issue In Chapter 5 of the Niagara R2 Modbus integration manual, the following note describes the JDE "View Cache": ... After viewing linked Gx objects in JDE, polling will continue for the associated shadow objects in PollOnDemand containers until that view is removed from the view cache. Typically, this means 4 view changes before polling stops... In an effort to reduce the number of shadow objects being polled (on a large job), can the 4 view changes, that are cached, be reduced to zero? Product Line TAC IA Series Environment Niagara R2 Modbus Cause The 4 view changes are by design. Resolution There is no way to configure the number of view changes or manually clear the cache.  Closing the JDE and re-opening it is the only way to stop the values from updating.

Issue A job site has a Lutron lighting system called the GRAFIK Eye QS.  It comes with a network interface with model number QSE-CI-NWK-E.  Will this allow the system to integrate to Niagara G3? Environment Niagara G3 Cause Lighting system installed on a jobsite and end customer would like to integrate to the building automation system (Niagara G3). Resolution The Lutron network interface QSE-CI-NWK-E provides an interface to a Windows-based platform via a RS-232 or TCP/IP connection.  It is a "text-based" interface meaning commands are sent via a terminal program like HyperTerminal. In order to interface the GRAFIK Eye QS to Niagara, the FlexSerial Driver can be used.  This driver can be configured to communicate to a wide range of "simple" serial communicating devices.  It allows the user to model the native device messages like framing details and payload content. The part number for the FlexSerial drive is ENC-DRV-FLEX.  It is an option for the ENC-520, Jace-6, Jace-7, and Jace-Nxt.

Issue Attempting to send email with I/A Series G3 and the SMTP server responds with an error "Must issue a STARTTLS command first." Environment I/A Series G3 Cause The targeted SMTP server requires an SSL / TLS encrypted connection.  SSL (Secure Sockets Layer) allows for the encryption of HTTP traffic between an ENC/ENS and a remote client. Encryption of the Fox and Platform protocol is not supported.  This implementation is supported with G3 versions 3.3 and above.  SSL can also be used to connect to a SSL enabled SMTP mail server to protect email credentials and the email message being transmitted.  Using SSL with SMTP is supported on version 3.4.55, 3.5.5, 3.6.31 or later.  As always it is recommended to use the latest maintenance build for each version of Niagara G3. Resolution The I/A Series G3 platform currently supports SSL encryption only.  Requires purchase of the crypto feature IA-SSL that adds the following line to the base license. Contact Customer Care at 888-444-1311 to order (Part Number IA-SSL).  The Host ID for the ENC/ENS must be provided on the associated license form with the order.  The following feature will be added to the license. crypto ssl="true", parts="IA-SSL" Install Updated License - Once the updated license is received, install the license into the ENC / ENS using Workbench.  Do not reboot when asked, you will reboot after updating the Crypto module. Install Crypto module - Use the Software Manager in the Platform to install the crypto module.  Allow the ENC to reboot. Install Crypto Service - Add Crypto Service to Services folder. Configure Web Service (Only do this if you plan on using SSL with the Web Server).  Enable the Https Enabled property.  Change the Http Port to an unpublished port, such as 31876. This is required to prevent users from using HTTP logon.  Do not enable HTTPS Only.   This will cause the Fox Protocol not to function. Configure Outgoing Mail Server (Only if SSL is required for email).  Configure as normal, except use SSL port for the port number and enable the Use Ssl property.  Contact your email provider for proper hostname and port number for SSL.

Issue Adding an I/A Series R2 BACnet Binary Output object for a Functional Devices RIBTW2401B-BC RIB relay module causes the device to drop offline (down status).  The output window displays the following error. ERROR: Unable to convert class tridium.foundation.dataspecies.DsEnum from ASN type 9 tridiumx.bacnet.asn.ASNException E_BACNET_ASN_INVALID_TAG {tagNumber 9 current tag 0} BACnetDevice: RIB01 is now down Environment I/A Series R2, BACnet, Functional Devices RIBTW2401B-BC Cause The Functional Devices RIBTW2401B-BC RIB relay module appears to have an issue in processing the device status while polling priorityArray points.  The device responds incorrectly to the UNC's status message request. The problem is related to the BACnet stack of the device.  Resolution The only workaround is to disable the device ping mechanism in the I/A Series R2 UNC's BACnet service (Device Status tab) and reboot the UNC. Make sure to backup when requested to save the changes.

Issue Have used tuning parameters that have worked good other places but at this site the loop output hunts continuously.  How do I properly tune this PI loop? Environment MNL-V2 or other temperature controller Proportional hot water valve for the reheat control. Cause  Loop was tuned too tight causing continuous hunting that resulted in premature failure of the actuator. Resolution The following information is paraphrased from a number of previously published HVAC controls documents. Using only proportional control, adjust the Throttling range (TR) until the loop control is stable with no oscillation. The desired control range x 2.5 is a good TR to start with.  When the loop is still oscillating, note the period of oscillation (in minutes). You may need to increase the TR to 25 or more to achieve stability in the loop output.  You must achieve stable control before continuing.  If proportional control cannot stabilize the loop, adding integral and/or derivative will cause further instability. Make a step change (5 to 10%) in the setpoint.  If the system does not stabilize after a few minutes, repeat step 1. Increase the TR by an additional 5% to 30%. Use the following formula to calculate the initial value to be used for the integral value:       i = 1 / [ ( Loop period in Minutes ) x 2 ] Monitor loop to evaluate response,  If the response is slow with integral action, increase the "i" value slightly.  It may be necessary to upset the loop, by changing the setpoint, to get a good test of the loop response.  The final integral value is typically in the range of 0.05 to 0.5. In most cases HVAC control loops do not require derivative action.  Improperly tuning the derivative action can result in poorer control than without any derivative action.  The following formula can be used to determine a starting value for the derivative value:      d = (Loop period in Minutes) / 8 This value may need adjustment to optimize the control.

Issue I/A Series G3 schedule times can only be adjusted in half hour increments? Environment I/A Series G3 versions 3.3.22, 3.4.51, and 3.5.25 Cause Schedule module and associated user interface is not correctly processing the time setting causing the time to round to the nearest half hour increment. Resolution Note: It is recommended to upgrade to the latest maintenance build for the I/A Series G3 version being used. If this is not possible, updated schedule modules are available for download from https://ecobuilding.schneider-electric.com website.
