Issue Several Xenta 102-AX controllers need to have the CO 2 sensor shared among them in a LNS environment. Product Line TAC Vista Environment CO 2 (Carbon Dioxide) Xenta 102-AX nviCO2 nvoCO2sensor Cause Properly binding a CO 2 sensor output to multiple Xenta 102-AX VAVs. Resolution From the Xenta 102-AX VAV that is connected to the CO 2 sensor, create a binding from the UnivIn3Sense function block/nvoCO2sensor, to VAV_Controller function block/nviCO2 in the receiving Xenta 102-AX VAVs. It will also be necessary to set the send heart beats by following Values sent from a 102-AX via SNVT bindings are not making it to the receiving controller.

Issue Can not connect a SCU controller directly to a Xenta Product Line TAC INET Environment I/NET controllers Xenta controllers Cause No Communication between a Xenta and a SCU controller. A SCU controller can not communicate directly to a Xenta because they speak different protocols. Resolution There must be an interface between an SCU and a Xenta controller, like a 7798C controller for example. The 7798C translates communications from a Sublan to a CLan. It also has a database that keeps track of rules set up by the admin. For a deeper understanding please review Explain and define I/NET Ethernet, C-LAN, and Sub-LAN communication.

Issue Continuum worked fine and after a reboot of the workstation, now not receiving alarms and/or controller online/offlines. Product Line Andover Continuum Environment Continuum Cyberstation CX controllers Continuum alarms Cause Communications issues between cyberstation and controllers. Resolution Continuum supports only one network card (NIC) in a Cyberstation. Dual NIC configuration not supported. Note: The issue with dual NIC is that when  PC is rebooted there is no guarantee which NIC will become #1 or #2. Please see Cyberstation Access Event Views do not show live events but work on other Cyberstations as well.

Issue When integrating a Integral DVR system Vista crashes Video does not work in Vista CCTV video loss in Vista Product Line Pelco, TAC Vista Environment Vista 5.1.3 Vista Integral DVR SDK v6.6.1.57 Integral DVR SDK v7.0.8 Cause Vista uses the same SDK as Controlpoint uses for an Integral DVR system, this mainly means that Vista SDK needs to be at the same versions as Controlpoint's SDK. A good example of this would be that Vista 5.1.3 use SDK v6.6.1.57 and Integral Digital sentry 7 use a newer version of SDK that is not compatible with SDK v6.6.1.57, a integration of this system then causes Vista to crash. An integration with Vista 5.1.3 would need Integral Digital Sentry 4.1/4.2. Please reference Vista Video Compatibility for more information. Vista 5.1.5 has SDK 7.0.8.0 and it appears that HD support was not included prior to SDK7.0.24.0 Resolution Make sure you have the correct version of Integral Digital version versus Vista version.     5.1.5 5.1.4 5.1.3 5.1.2 5.1.1 5.1.0 5.0.3 5.0.2 5.0.1 5.0.0   Integral Digital Sentry 4.1/4.2 X X X X X X           Integral Digital Sentry 7 X X    

Issue At the end of an alarm delay if the point is still in alarm, Continuum will generate the alarm notification regardless of how many times the point has "return to normal" (RTN) during the delay period. If the point goes in to alarm again, Continuum will generate the alarm soon. There is a perception that the alarm delay calculagraph should be cleared when the point has RTN. Product Line Andover Continuum Environment Cyberstation IP level controller Field Controller Cause The behavior of the alarm delay calculagraph in some situations is not what would be expected. Resolution Create an infinityNumeric  point to trigger the alarm Create an program to set the alarm point to on/off For Example: The original alarm point is Fanfault, and delay time setting in the AlarmEnrollment is 60 seconds. Create an infinitynumeric named "Fan_alarm" and attach an AlarmEnrollment with a delay. Create the program below:  Line detecting: Fan_alarm=off if Fanfault is on then go to setting Line setting if Ts>=60 then Fan_alarm=on if Fanfault is off then goto detecting Line E state=enabled if ts>1 then go to detecting For more detail about AlarmDelay Operation, see AlarmDelay operation.

Issue The Area schedule assignments from "Loose" Areas (ones that are individually attached to the Personnel object) can interfere with those assigned through a Template. Product Line Andover Continuum Environment Continuum Access Control Cyberstation Cause Wish to remove the "loose" Areas so that those assigned by the Template take over. Resolution Here are two methods to do this that will resolve this issue. For large numbers of affected Personnel, use the Personnel Import Utility for this by removing the areas you do not want from the import file. You may need to re-apply the template you want after this as well. See How to conditionally assign areas to personnel objects using the Personnel Input Utility XSLT transformation file that describes this method.  For smaller numbers of Personnel the manual method may be better. For each Personnel object. Clear out template assignment. Save the object. Remove all Areas left assigned. Save the object. Re-assign the previous template. Save the object.

Issue Unable to view a report in webstation. When trying to open the report object in webstation the message "This report is dynamic and cannot be opened from webstation". Environment TAC Vista 5.1.X TAC Vista Webstation 5.1.X Cause As the message implies, reports are dynamic objects that cannot be viewed in webstation. Workstation is considered an engineering environment where objects are created and manipulated, whereas Webstation is primarily a viewing interface. Resolution For an alternative way of viewing the reports after carrying out the steps below, refer to this document on the Community: DOC-7604 Follow the steps below to be able to view a report in webstation: 1. Create a report - in this example named  "Report1". 2. Create a time Event object and set the appropriate interval eg. daily, weekly, monthly etc. 3. Create a Report Periodical in Vista. Link to your "Report1". 4. Link the Report periodical to your time event object (created in step 2). 5. Lastly, create a hyperlink to the location where you have saved the copy of the report.  

Issue When importing an old database into a new version of Vista, right click on a Xenta Server and select "Edit" to open the Xbuilder project. (Change the version information in the property of Xenta Server. Refer to "Edit" is not available in the right-click menu for a Xenta Server in Vista Workstation.) The old XBuilder project will automatically be upgraded to match the new version of XBuilder. However, the content of the project sometimes will be incorrect after this conversion. Product Line TAC Vista Environment Vista Workstation XBuilder Cause The XBuilder version of old the database does not match the one of the new database. Resolution Install the old version of XBuilder.  One PC can install several different versions of XBuilder. The standalone XBuilder installation file can be found on the Schneider Electric Exchange Extranet under "Engineering Tools"  Keep the Vista Server and Workstation etc. at the newer version.

Issue When you select the option to view the properties of a Object nothing appears. Environment Vista 5.1.7 Cause A Remote Desktop session is connected at the same time as a local user.  Resolution To allow the properties option to be displayed, log the Remote Desktop user off. The preferred option is to set the Remote desktop session to a single user session. Remote Desktop Protocol (RDP) / Remote Desktop Connection (RDC) and I/NET has more information on how to configure a single user setup.

Issue Enable or disable I/A Series R2 alarms via a graphic page Product Line TAC IA Series Environment I/A Series R2 Cause Alarming for an I/A Series R2 alarmable object can be disabled or enabled by accessing the object's properties, 'Alarm Setup' tab using WorkPlace Pro. In most cases, the end user is not going to use WorkPlace Pro to access the system. They will normally access the system via the graphic pages in a web browser. Resolution Create program logic in WorkPlace Pro and use Binary Output objects to link to the alarmable objects via 'Flex' objects. The BO objects can be linked to a GxPage. Below are 2 examples with an Analogue Input object and a Binary Input object. Enable / disable alarm for an AI object The FlexLimitEnableBits object can be found in tridiumx > programlib > control. Link the AI 'limitEnable' to the FlexLimitEnableBits 'link'. The BO to enable / disable the high limit alarm is to be linked to the FlexLimitEnableBits 'highLimitEnable'. The BO to enable / disable the low limit alarm is to be linked to the FlexLimitEnableBits 'lowLimitEnable'. Create suitable command texts for the BO objects.   Enable / disable alarm for a BI object The FlexBoolean object can be found in tridiumx > programlib > control. Link the BI 'alarmValueEnabled' to the FlexBoolean 'link'. The BO to enable / disable to alarm to be linked to the FlexBoolean 'propertyInput'. Create suitable command texts for the BO object. Note: The FlexLimitEnableBits object can only be found in programlib module version 2.301.532d.v1. Install this to the Enterprise Server or UNC to use it. Refer to How to install an I/A Series R2 JAR File for an example of the procedure to install an I/A Series R2 JAR file.

Issue I/A Series Software Compatibility with the Windows 7 Professional Operating System Product Line TAC IA Series Environment Microsoft Windows 7 Professional operating system (32-bit, 32-bit XP Mode, 64-bit XP Mode) WorkPlace Tech Tool (WPT) 5.7 and later PSI / XPSI  4.1 MNCI 4.0 MICROFLO Balance 4.0 PSOPRIF 11.6 Tree Tech 3.1 LON Flow Balance 3.0  Cause I/A Series software should only be run on tested and compatible equipment to avoid problems with software or hardware.

Issue AMT messages: Ind. D/L failed & DCU Queue ovflw Product Line TAC INET Environment I/NET Site Download failed Queue Overflow Cause Failure to communicate in C-LAN and SubLan Resolution For the Ind. D/L failed message in AMT, as well as SCU Lost, is from the Host Workstation. It is telling us that there was an error in downloading individual's information to the SCU. Explain and define I/NET Ethernet, C-LAN, and Sub-LAN communication has a drawing of a simple INET network, and how it is connected with labels for the names to help with understanding and terminology. Please note the resistors mentioned and make sure your site has these. Firmware: Check to make sure the same Firmware revision for the INET version you are running is in all the controllers. The DCU7798C is experiencing communication failure. Take a moment to check this as well as from 7798C to the SCU, check the resistors which are shown in the drawing, check the wiring, firmware, etc. That will resolve this failure. If you look closely at the screen shot, it even shows this is a door controller with exceptionally poor communication to the 7798C. It shows the door points. This shows you where to start with the troubleshooting. Distance: What is the distance between the controllers? I recommend the resistors on long runs or if you have a lot of controllers. If you have more than these two or they are a long way apart, then resistors, yes. If they are 2 meters from each other and it is just these two, then not that critical. The issue appears to be with the CLAN. The pulling down the communication is producing these errors. Check to make sure the wires are protected in conduits and not running along side power or Power-Over-Ethernet, or ballasts. These items can cause interference, which can cause this failure. Earth Ground: Is the issue on one or between two 7798Cs that are wired the same way? The second 7798C is probably giving the problems. The issue is no earth ground wire on the three terminal power plug. This is the ground that is used on the CLAN comm circuit. There will be LAN Reconfiguration from ALM, the second 7798C is failing on the CLAN communications.

Issue The space temperature (nvoSpaceTemp) is displaying an invalid or default value (either 621.81 degrees Fahrenheit or 327.67 degrees Celsius). In newer versions of Vista the value will display "Invalid Value". Product Line TAC Vista Environment Vista Workstation Xenta 104-A STR-150 LonMaker NL220 Cause The option to use the STR-150 wall module with display has not been selected. Resolution If using a Xenta controller with software older than version 1.2 see STR-150 Not Compatible With Software Version 1.1 Xenta 100 Series Controllers. Otherwise, there are two ways to correct the problem: Using the Xenta 104-A Plug-In Open the 104-A plug-in. Select the General tab. Verify that the "Enable wall module with display" box has been checked. Click Apply or OK. Using Vista Workstation In the tree menu find and open the Xenta 104-A. Open the "8030" object. Locate and double-click nciAppOptions. Verify that Bit 14 has been checked and click OK.

Issue Under multiple PC environments, the time of a DCU changes automatically for a specific period. The time of the Server/Filemaster is correct. Product Line TAC INET Environment I/NET Multiple PCs environment Cause For multiple PC environments, the time setting of each PC does not synchronize. The time of Server/Filemaster is correct, but the time of Remote Client/Equalized Client may be not correct. If there is a DCU Synchronization function set on the Remote Client/Equalized Client, the wrong time will synchronize to the DCU for specific period set in the function of DCU Synchronization. Resolution Synchronize the time on Remote Client/Equalized Client with Server/Filemaster through NTP or manually. The other way is only to set DCU Synchronization function on Server/Filemaster, not on Remote Client/Equalized Client. The NTP as of March 1, 2013 no longer works. See Time sync is no longer working for suggestions

Issue Attempts to download images or object files to UNC532 controllers only partially download then fail. This is often seen in the Sigma debug window. Product Line Satchwell Sigma Environment Sigma Ethernet ARCnet UNC532 Cause Large quantities of Sigma global data can adversely affect the ability of the slower processing controllers such as the UNC532 from accepting large files due to communication timeouts.   From experience this affect has been with global levels of 600 broadcasts per minute. Resolution If there are problems on site with downloading files then checking the global broadcast rates can be achieved by; Using Wireshark to trace the Ethernet Backbone communications  (See Using WireShark to analyse communications on an Ethernet network) Email the trace to Product Support and request a global data analysis.

Issue Can not connect to a Remote RAS Controller Product Line Andover Continuum Environment RAS Connections to: CX9900, CX9940, CMX9924, CX9400, CX9200 Controllers with HyperTerminal support Modem connections, Dial Up Cause Can not dial up remote site over RAS connection What settings need to be checked? Resolution For assistance with troubleshooting RAS connections download the v1.9 Continuum Remote Communication Configuration Guide For older versions of Cyberstation also check out the RAS guide installed on the Cyberstation along with the Continuum software. The following settings/ configuration should be checked to help isolate the issue where a site can not be connected: Verify phone line is giving correct cadence ring tone that can be detected by the modem, some internal phone/ exchange lines give non standard tones and may not be answered by the modem . Using another External phone line verify can log on to the controller with hyperterminal using the Baud rate chosen at front end (usually 19200). See the link below for details on using the Command Terminal interface.  If Modems do not answer - Check the correct AT commands have been sent to the modem at the selected baud rate, also verify the cable is 9 cores and a DCE - DTE (Straight through cable). Ensure AT settings have been saved in the modems non-volatile memory. Verify all commport setting match the front end database settings and match any other working sites. Typically 19200 baud, 8 data bits No parity 1 stop bit. Ensure this matches the front end settings when checked using command line as on older versions of Cyberstation the comm ports screen does not always show the correct values. Verify "Track CXD" is selected and "Direct Connect" is not. Verify the Comm port "DefaultBaud"  attribute is set to the same value as the Baud rate used, so that the connection can be made following a power fail. Verify comm port flow control matches the front end, typically hardware & software XonXoffCtsRts Once successfully connected with Hyperterminal and all settings match front end ensure the port is logged off before trying to connect from the Cyberstation. If Cyberstation can not connect to any remote site, first connect a Laptop running Hyperterminal to the front end modem and dial it up from another line to verify the modem & cable are operating correctly. Then go through the software and remote site configuration as detailed in the RAS Guide. Verify Cyberstation is running on XP or Win2000 operating systems as appropriate from Compatibility matrix - See RAS is not supported in Microsoft Vista and Windows 7 for use with Continuum. Also see Continuum controllers and Remote Access Communication for information on controllers that support RAS as an Access point.  For testing with Hyperterminal, download the Command Terminal Configuration Guide

Issue Is there an updated list of all tested devices using the M-bus Xdriver? Environment Xdriver Cause Would like to know what devices have been successfully tested with the M-bus Xdriver. Resolution The current M-bus Xdriver Manual lists several devices that have been tested. The question of what devices have been tested with various Xdrivers comes up now and then. The group that develops Xdrivers is not chartered to continuously test new devices with the drivers and does not maintain a list of devices that others claim to have successfully implemented. There are likely dozens of other M Bus devices our branches/partners have used successfully but we do not capture/verify this info.   There two best options for attempting to get this information are: 1. Ask on the Continuum Community Forum (https://community.se.com/community/bms/continuum) or 2. Obtain the product and bench test it.
