Issue Open a graphics, all the objects' value display normally, when there is a  power cycle on the controller which the objects resided., the graphics will  not poll the objects' value, unless reopen the graphics or move to design mode then go back to run mode. Environment BCX1 b3s Cyberstation 1.94 SQL express 2005 + Windows 7 SQL server 2008 R2 +Windows server 2008 SP2 Cause Controller is in a heavily workload condition, the scan value reaches to high value Write value to the point under another controller but the controller is offline or there is some communication failure, although the scan is low but the program not work Resolution Delete or disable the program Modify the program to make sure the scan value is not greater than 1

Issue On a DMS jobsite, Operator Interface (OPRIF) does not display the MicroSmart controllers on the screen.  There are a dozen controllers and they are confirmed as communicating to the DMS but they do not appear in the controller list in OPRIF. Environment OPRIF DMS MicroSmart Cause In OPRIF, the MicroSmart controller list displays 32 controllers per screen and it reserves spaces even if that controller address does not exist on the jobsite. If the controller addresses begin with number 33, then the first screen will appear as blank.  However, the second screen will list controllers 33 to 65. Resolution Use the Page Down and Page Up buttons to move back and forth between controller lists 1-32 and 33-65.

Issue After configuring an XDriver point, clicking the refresh button on the editor results in an error "Invalid system enumeration" and no value response from the Slave device. Environment BCX1 Cyberstation 1.9X Modbus RTU Cause There is a register number shift (+1 or -1) some equipment uses. The registers listed in the manual do not actually exist. Resolution Add a register number shift (+1 or -1) to the register number listed in the manual.

Issue An "Invalid Pointer" error message is displayed when attempting to open an existing project in the WorkPlace Tech Tool software. Environment WorkPlace Tech Tool release 5.x.x Cause The WorkPlace Tech Tool project database file (project-name.wtp) is missing or is corrupted. Resolution Use the WorkPlace Tech Tool software to recreate the project and reassociate the applications with the project. Navigate to the project folder using Windows Explorer. If the a .wtp project database file is present, rename the file, by adding .save to the end of the existing .wtp file name, for example, rename My_Project.wtp to My_Project.wtp.save Close Windows Explorer. Open WorkPlace Tech but do not open the project. Under the WPT Project Menu, select New Specify the name of the project. Use the same name as the existing project folder. Using my example from step 2, you would create the project named My_Project In the displayed "Add Application to Project From..." window, select the "Unassigned File" tab. All existing applications for that project will appear in the list. Select them all by holding down the [Ctrl] key on your keyboard and clicking on each file shown in the list. Click the [OK] button at the bottom of the window to add all the selected applications to the newly created project. Exit from the Workplace Tech Tool software. When you reopen this project, all applications should be shown and any of them should open properly.

Issue How many SQL client licenses to run SQL if SQL 2008 is used to run Report Server? When Report Server is installed, is there a connection between SQL and the Enterprise Server. Environment Report Server Licensing Cause Licenses must be purchased for supporting software (OS, SQL, etc). Resolution Because SQL and Report Server have to be running on the same machine, there is only one sequel user that requires licensing.  There is no connection between the Enterprise Server and SQL when Report Server is installed.

Issue Unable to log into Reports Server after upgrade Environment Reports Server Cause The Enterprise Server Address must be correctly entered in the required fields during the upgrade.

Issue What is the difference between Crompton and Modbus? Environment IC3-Modbus IC-Modbus Cause Adding Modbus slave devices to a network that have Crompton devices and the IC Modbus is set to Crompton. Resolution The IC Modbus when set to MODbus reads 16bit registers separately. It can add 2 consecutive 16 bit registers together to make a 32 bit word. The IC Modbus when set to Crompton reads a single 32 bit register. Crompton uses 32 bit registers. Therefore Modbus and Crompton slave devices cannot be mixed on the same IC Modbus network.

Issue The thermostat appears to be in OFF mode and can't be cycled through the modes as indicated by the manufacturer's directions.   Environment Venstar T2700, VST2700 thermostats for red-wire control connected physically to a controller Cause It seems that the polarity of the dry contact was set to the default Normally Open (NO) state. Using the Venstar EZ-Programmer to apply the correct settings for use with an occupancy point did not overwrite the polarity of the Venstar's dry contact, but did overwrite the Dry Contact Operation. Also, by wiring everything up first, we did not power up the thermostat to change the mode before it got the closed dry contact command from the BAS. So when we did power everything up, the dry contact was closed, but the thermostat understood that this was an "unoccupied" command since it was still set to NO. Even though the security settings allowed the mode to be changed, when Dry Contact Operation is enabled, the mode can only be changed in occupied mode. When the thermostat goes unoccupied, it stays in whatever mode it was in previously, and controls to the unoccupied setpoints. By not realizing that the EZ Programmer didn't overwrite the polarity, we assumed the dry contact operation and polarity were correct and a closed dry contact would enable the occupied mode.   Resolution This issue can be resolved by powering up the thermostat before connecting the dry contact relay and changing the mode to "auto". If already wired, make sure the dry contact polarity is set to Normally Closed (NC) and Dry Contact Operation is "Yes". Then the modes can be cycled while occupied. < acc0432manualrev1.pdf="" manuals="" support="" www.venstar.com="">

Issue What is the procedure for using a BCX9640 to replace a CX controller. Environment BCX9640 Comm Port Cause Need to change the Infinet Controller type. Resolution A BCX9640 is not the preferred replacement for a NetController for several reasons, among which are the following..  Can only support one Infinet port (Comm 2). Does not support L-Bus Does not support IO Module control. The process for replacing a NetController with a BCX9640 is as follows. Print a list view off all Infinet Controllers under the NetController.  This list must include the following columns... SerialNum CntrlType InfinetID Create a new BCX9640 with a new ACCID and bring it online. Switch Cyberstation to offline editing mode. Change the serial numbers of all Infinet Controllers under the NetController false serial number (so that the serial number for each Infinet Controller will be available for each new Infinet Controllers created under the BCX9640). With the workstation in Offline mode, manually create all the Infinet Controller object that existed under Comm 2 of the BCX9640.  Use the following information, The same controller model that the Infinet Controller had under the NetController. The same Infinet ID that the Infinet Controller had under the NetController. Drag and drop copy all the points and programs from the original controller to the new controller. Verify that all the points and programs were correctly copied and are intact. Go into the new Infinet Controllers and change their serial numbers to the serial number it had under the NetController. Next go back to online editing. At this point you should see all your infinet controllers come back on line. Finally reload the complete site. It is important to note that any controllers that are referencing points in the relocated controllers will have to have these object references verified and repaired in cases where the references have been lost.

Issue Uninstalling KB2858725 removed MS Dot Net 4.0 from the system and Web Client no longer accepts connections. Product Line Andover Continuum Environment Continuum 1.9x Windows 7 Windows 2008 Server Windows 2008R2 Server Cause Removal of KB2858725 not only removes the update it also removes Microsoft Dot Net 4, Dot Net 4.0 Client and Dot Net 4.5 extended. Resolution   Microsoft Dot Net 4.0 Extended. http://microsoft-framework-4-extended.en.lo4d.com/ Reinstall Microsoft Dot Net 4.0 Client profile. http://www.microsoft.com/en-us/download/details.aspx?id=24872 Note: Link to TPA-CONT-13-0005.00 for .Net Control errors with schedules once update for 4.5.1 is installed.

Issue A floating control reheat valve is wired to the digital triac outputs of a MicroSmart controller.  After a few hours of operation, the valve position does not match with the expected position as provided by the real-time display.  Is there a way to synchronize the actual position with the real-time display without power-cycling the controller? Environment DMS MicroSmart (any with triac outputs) Cause Intrinsic design issue with floating actuators with built-in feedback. Resolution One option is to write a UDP that toggles valve control using a STOP command and then an AUTO command on the analog output point. Ensure the STOP command action is RANLO (range low) which will swing the actuator to its fully open or fully closed position.  The AUTO command will restore dynamic control via its control loop. In between the STOP and AUTO commands, insert a delay of 120 seconds to give the actuator time to get to its fully open or fully closed position.  If the actuator needs more or less than 120 seconds, modify it accordingly. Run the UDP on a timer of every 4 hours.

Issue For Modbus RTU Xdriver, if poll too much points or polling is too fast with one xdriver will cause reading 0 issue. Environment Continuum 1.9X BCX1-CR, Modbus RTU xdriver Cause Poll too much points with one xdriver or polling is too fast ,more than 2 polls per second More than one programs polling at the same time Resolution  Make sure there is only 1 PE program running to Poll the xdriver points Slow down the polls rate ,make sure it is under 2 polls per second,  If the issue still exist, please do the following steps Create a mirror point for each xdriver point,and fill the mirror point in AnnexPoint of Xdriver Point configuration tag Create an infinityfunction called PollFunction( as a example) in the BCX1 as below:           Arg 1 XdriverPoint Numeric count ,i,temp For count=1 to i Next count temp=xdriverPoint Return(temp)      4. Creat the poll program in BCX1 like below Numeric count,i,temp, Caller Line initial if caller is 0 then goto 1 line 1 i=200 temp=PollFunction(XdriverPoint1) DisplayPoint1=AnnexPoint1/rate1 goto 2 line 2 temp=PollFunction(XdriverPoint2) DisplayPoint2=AnnexPoint2/rate2 ... goto waitting line waitting Caller=1 goto Initial 5, Follow step4 , create another poll program to poll more xdriver points, change the sytax to caller=1,2....n in the Initial line, and change the sytax to caller=2,3,.....0 in the waitting line to assure there is only one program does poll xdriver point at the same time. After configure annexpoint, annexpoint will keep the good value and ingore the bad value.

Environment StruxureWare Building operations 1.4 Cause If a user do one invalid logon attempt this account will be locked until the AS is connected to the ES again. Resolution If the AS is not connected to the ES don't do invalid logon attempts. Make sure to type in the correct password. 

Issue Do we have any official statements if Windows updates should be installed on computers running a Vista server?  Environment TAC Vista Cause As TAC Vista is using Windows components there is always a very small risk that TAC Vista could run in to trouble when installing a Windows update. But on the other hand if not installing Window updates the computer could run in to trouble and then Vista will crash too. Resolution There is no official statement saying if Windows updates should be installed on a TAC Vista site, it is up to the engineers on site to take that decision.
