The override switch is a trigger to provide cooling to the area served. Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Cause Provide end user a simple way to get comfort cooling Resolution Interface the override switch to DI 01 on the SE7600H5045B. It will then be accessible via BACnet to trigger comfort cooling.

Issue When trying to discover via BACnet they broadcast the same instance ID. Need Dent Viewpoint software and RS485 converter to change the Instance ID prior to doing Find New BACnet Devices. Environment BACnet MSTP Cause Documentation Resolution Use Dent Viewpoint software and RS485 converter to change the Instance ID prior to doing Find New BACnet Devices.

Issue No connection to Lon controllers from VisiSat Environment VisiSat Windows 7 Cause The Echelon Lon driver implementation in VisiSat does not support Windows 7. That means that if VisiSat is installed on Windows 7 (possible from version 2.1.185) it is not possible to use the Lon connection from VisiSat Resolution Install VisiSat on Windows XP to use the Lon connection

Issue  64-061-31 is no longer available and needs to be replaced Environment 64-061-31  TAC valve TAC DWV - PN 6 DN 32  Cause valve no longer available Resolution This old TAC Valve is no longer in production, Schneider Electric do not have any PN6 valves. It's mainly Germany/Austria that uses PN6 valves. Dimensionally they are the same as PN16 valves, the main difference is the wall thickness but in all practical terms it costs more to have two separate tools for each valve PN hence why Schneider and 90% of other suppliers just have PN16 even though they may only ever be used under 6 bar static pressure. As a replacement flanged valve, DN32, the V211 valve is suggested

Issue When trying to update the OS of a BCX9640 to a BCX4040, the update process seems to succeed but the controller remains unchanged after the update process completes. Continuum indicates no errors during the update process. Environment Convert BCX BCX9640 BCX4040 Update OS Firmware Cause Incompatible bootloader. Resolution Update the controller to the most current version of OS for the same controller model before updating the OS with the new model firmware.

Issue A BVSPP point of a MNB controller cannot be changed from G3. MNB controller is at firmware version 1.43. An “ASN error:” is displayed for value in the BACnet Discovery window when discovered in G3. Environment G3, WorkPlace Tech, All MNB controllers Cause The MNB application’s BVSPP object was initialized with “NA” in WorkPlace Tech.  The BVSPP object should only be initialized with “On” or “Off”.  The ability to initialize an object with “NA” will be removed in a future version of WorkPlace Tech. Resolution Use WorkPlace Tech to change BVSPP initialized with “NA” to either “On” or “Off” and download application to controller. If the point still cannot be change from Workbench, then delete the point in the ENC/ENS database, rediscover it and add it back to the G3 database.  The BVSPP point can now be changed from G3.  

Issue When updating to SmartStruxure 1.5 BACnet IP devices go offline from either ES or AS Environment SmartStruxure Automation Server SmartStruxure Enterprise Server Cause The upgrade to SBO 1.5 can sometimes cause the BACnet IP network interface to lose the IP broadcast address. Resolution Verify the BACnet IP Network interface configuration to see if anything has been lost. Re-enter settings for IP broadcast address to establish connection with BACnet devices again.

Issue For unknown reason, BCX4040 goes offline with solid CPU light, and failed to ping, Webpage can't be accessed, Environment BCX4040 Cyberstation 1.80 and above Cause Not clear what cause this issue, Not all the BCX4040 with solid CPU light can be recovered. Resolution Press "reset" button on PCB board for a long time, at least over 10 seconds, if the CPU light goes off, it is possible to recover the BCX4040 Press "IP Reset" on PCB board for over 60 seconds, Maybe not bring the controller into factory default setting Ping the BCX4040, if success, go to the next steps Start Continuum, and bring BCX4040 online, then downlaod, According to the steps above, I have recovered at least 4 BCX4040 and AX5720/5740.

Issue Getting a “500: Internal Server Error” when clicking on hyperlink in G3 station. The following error is also displayed in the Application Director window: javax.baja.naming.SyntaxException: Illegal char '?' in body: /ord?file:^gfx_Lib/www/nav.htm javax.baja.naming.SyntaxException: Illegal char '?' in body: /ord?file:^gfx_Lib/www/Top.htm Note:  The last part of the file path after "file:" will be different based on your station's file structure.   Environment Niagara G3, version 3.8.37 Cause A second “/” mark was being added to the hyperlinks’ paths in the htm file.  In this case, hyperlinks in the Top.htm file are the culprit. The Hyperlinks read: To date, Tridium has not determined how the second slash gets added.   Resolution The solution is to find out which htm file contains the error and correct it. Use WorkBench’s Text File Editor to examine the htm file to find the error.  - Open the station’s Files folder  - Right-click on the htm file and select “Text File Editor” - Once the htm file is found that contain the error, remove all second slashes.      Change <a href="/ord/?...     To          <a href="/ord?... (removed the second “/”) - Save changes and reopen page in new browser Note: There may be a need to clear all caches.   

Issue If the conversion line on an input is more complex than a single line of script, can a function be used? Environment BACnet b3 Controller Analog input conversions / scaling. Script programming, functions Cause The code required to scale an input is more complex than a single line of code. Resolution It is not possible to use a Script Function in the conversion line of an input point, however quite complex formulas can still be entered that scale the ElecValue when the point is evaluated. The format of an input point conversion line is still:     ElecValue / 1000   The automatic scaling table is also available in the b3 inputs for linear conversions

Issue After restoring a backup set to an AS, MSTP communication is lost and no BACnet folder appears under the System Hardware folder. Environment AS System Time Backup Restore Cause System time was not set in the AS prior to restoring the backup. Resolution Set system time prior to restoring the backup. The BACnet folder may be restored if the AS system time is set subsequent to restoring the backup and the AS is warmstarted.

Issue At times it is necessary to monitor an external variable to trigger action in SmartStuxure Lite Environment Smart Struxure Lite Smart Struxure Continuum AS MPM Windows 7 Windows Server 2008 Cause Need the ability to trigger actions from an external variable to run a lua script Resolution Use a lua script in your MPM that copies the value of ME.PG#_ENABLE.value to an Analog/binary value. This value can then be seen from the AS or BCX through bacnet and you can have the AS or BCX do different functions depending on that value

Issue Is R2 or G3 compatible with JAVA 8? Product Line TAC IA Series Environment R2 G3 Cause Oracle released Java 8 Resolution At the time of the creation of this article (February 17, 2015) no versions of R2  have been tested with Java 8 and therefore Java 8 is not supported until further notice.  As of March 15, 2015, Tridium has now tested the latest maintenance builds of G3 releases 3.6, 3.7 and 3.8 and found that they appear to work properly with Java 8 update 31.

Issue @TriggeredTimeStamp does not always report the last time an object transitioned to an off-normal state. Environment Alarms Substitution Codes Event Notifications. Cause Both the Normal and the Reset alarm states represent conditions where the alarmed object has assumed an acceptable value and is not in alarm Reset = The object has returned to a normal state but the return to normal notification has not been acknowledged. Normal = The object has returned to a normal state and the return to normal notification has been acknowledged. The TriggeredTimeStamp value is updated only when the object transitions from a Reset Alarm State to an Alarm Alarm state. The TriggeredTimeStamp value is not updated when the object transitions from an Alarm Alarm State to a Reset Alarm state. If an object goes into alarm and that alarm event is never again acknowleged, the Triggered Time Stamp will continue to reflect that initial alarm transition time regardless of how many times the object goes into and out of an alarm state. Resolution In order to get the Triggered Time Stamp to update, the notification must be acknowleged so that the alarm can return to a Normal state (rather than Alarm State = Reset) before it transitions to Alarm. 

Issue An offline edit in PCS deploys successfully. When viewed in Workstation, the Automation Server is online, but all b3s are offline. Product Line EcoStruxure Building Operation Environment SmartStruxure 1.50 PCS AS 1.5 BACnet interface Cause The b3s have a BACnet Device ID which is different from that assigned to b3s in PCS. The BACnet device ID can not be modified in PCS after it has been assigned. Resolution It is best to modify the BACnet Device ID in Continuum: Use a BCX4040. Connect with b3 devices one by one or together Bring b3s online in Continuum Workstation Modify the BACnet Device ID for each b3 to the BACnet Device ID assigned in PCS Go back to SBO Workstation. b3s should be online.

Issue Trend log values from two or more M-bus meters under a Xenta Server are intermittently mixed up, also when viewing a trend log page in the Xenta Server's web interface. Values from meter 1 are (sometimes) logged in meter 2's trend log and/or vice versa. Environment Xenta 913 Xenta 701 Xenta 711 Xenta 721 Xenta 731 M-bus meter Cause When secondary addressing is used for the meters, there is an extra telegram sent from the Xenta Server before asking for the actual values/data. The M-bus meters then replies to this telegram so that the Xenta Server knows which secondary address belongs to which meter. In some cases (only seen with a few meters) these addresses seems to be intermittently mixed up and this will cause the issue described above.  Resolution Use primary addressing for the M-bus meters.

Issue Replaced a Niagara R2 UNC with a Jace-645 embedded with R2.  LON communications was stable at first but now it is intermittent.  Environment Niagara G3 - AX version 3.6.47 or higher Niagara R2 version 535 Cause The intermittent LON communications issue was identified and a supporting jar file in R2-535 needs to be upgraded. Resolution Replace the lonworks jar file with this updated version:   lonworks-2.301.535c

Issue After about 30 minutes of communicating fine they will go off line in the AS. Environment BACnet, AS v1.41 Cause Time sync service running on the Lynxspring JACEs Resolution Restarting the Lynxspring controllers temporarily resolves the offline problem. Turning OFF the time sync service running on the Lynxspring JACEs permanently resolved the offline problem. 

Issue BACnet points are not updating in the UNC after the replacement of a BACnet device. Environment Niagara R2, UNC 520 Cause Tech replaced a drive from one manufacturer with a drive from a different manufacturer. The BACnet device object in the UNC was reused. Since the replacement drive was not the same model or manufacturer as the one being replaced, the BACnet points between the two devices are different. The points in the replacement device do not match the points in the reused BACnet device object in the UNC. Resolution The solution would be to delete the BACnet device object in the UNC, discover the replacement device and learn it into the UNC.

Issue Issues with port 80 after  WebReport installed on same machine as ES Environment ES WebReport Cause Port 80 conflict Resolution If you installed everything on the same machine and you didn't change the port on the ES you need to make some changes to avoid port 80 contention First change the ES port from 80 to something else like 8080    Open StruxureWare Building Operation Software Administrator    Change the default port from 80 to 8080    Stop and Restart the Service    Open StruxureWare Building Operation Workstation    Be sure to log in using @localhost:8080 instead of @localhost:80 Then you need to reconfigure WebReport to let I know the ES is using port 8080, this is normally specified during installation, there is an utility that lets you change it very easily which can be downloaded from the community.
