Issue Can a digital clock be used to replace an analog clock on a SVT4201? Environment SVT SVT4201 SVT4251 Cause Can a digital clock be used to replace an analog clock on a SVT4201? Resolution A digital clock cannot replace an analog clock in a SVT4201, because the SVT4201 and SVT4251 have a slight difference in components used.

Issue In LonMaker drawing, the TAC device stencils have disappeared. Environment LonMaker Visio Cause Either the TAC ToolPack was not installed, or the stencil view has been closed. Resolution To open the TAC stencils, click on File menu, go to Shapes and select desired stencil group. If the stencil is not available from this menu, then the TAC ToolPack was not successfully installed.

Issue It may be desirable to the building management to remove web users and operators' privileges to change their own password. Environment Xenta Server Cause By default all users are able to change their own passwords. Resolution While the privilege that each user has to be able to change their password cannot be removed through standard configuration methods, it can, nevertheless, be removed through the FTP server of the Xenta controller. However, these changes will apply to all web users or to all operators rather than just specific users. Connect to the FTP of the Xenta 5/7/9xx controller by typing FTP://x.x.x.x (where x.x.x.x is the IP address of the controller) in the Windows Explorer address bar. Login with the root username and root password. Browse to the ftp://x.x.x.x/www/config/ folder and copy the either the file named operatormenu.xml or webusermenu.xml (depending on which type of user needs to be edited) and copy it to the desktop of the local machine. Open the ftp.cfg file with notepad on the local machine. If you are editing the web user file then delete the following lines: <MENU name="User Administration" value="/wm/useradmin" type="CFGDIR"> <MENU name="Change Password" value="/wm/useradmin/change_password" type="CFGPAGE"/> </MENU> If you are editing the operator file then only delete the following lines: <MENU name="Change Password" value="/wm/useradmin/change_password" type="CFGPAGE"/> </MENU> Save the file to the desktop without changing the name. In the FTP rename the original file by adding a "1" to the end of the name. For example webusermenu.xml would now be named webusermenu1.xml. This way you can keep the original file in the FTP if you ever need to revert back to it. Copy the newly edited file from the desktop to the FTP folder. If you are already logged into the Xenta server then log out and log back in. The menu should no longer be available. Important Note: If the system program is reloaded in the Xenta Server, these changes will be over-written and will need to be re-done.

Issue While opening a TGML graphic in webstation a security warning dialog box appears: 'Java has discovered application itemsthat could indicate a security concern'. Environment Webstation 5.1.X Java 6 update 19 and newer Cause Signed Java Web Start applications and applets that contain signed and unsigned items could potentially be unsafe unless the mixed code was intended by the application vendor. As of the Java SE 6 Update 19 release, when a program contains both signed and unsigned items, a warning dialog is raised. Resolution Mixed Code Protection Options for Users: User can manage how mixed code programs are handled through the Java Control Panel. To access the Java Control Panel goto, Start menu > Control Panel > Java Control Panel > Advanced > Security. The following screen shot shows the four levels of control available. See the Mixed code heading towards the bottom of the Java Control Panel. Below are the details of the available options. Enable - show warning if needed.This is the default setting. When a potential security risk is encountered, a warning dialog is raised. Clicking Yes blocks potentially unsafe items from running and may terminate the program. When the user clicks No, the application or applet continues execution with protections (packages or resources that are later encountered with the same names but have different trust levels, i.e., signed vs unsigned, will not be loaded). Enable - hide warning and run with protections.This option suppresses the warning dialog. The code executes as if the user had clicked No from the warning dialog. Enable - hide warning and don't run untrusted code.This option suppresses the warning dialog and behaves as if the user had clicked Yes from the warning dialog. Disable verification.This option is not recommended. This option completely disables the software from checking for mixing trusted and untrusted code, leaving the user to run potentially unsafe code without protections.

Issue MR-VAV-AX output 3 set to an AO instead of a DO Environment MR-VAV-AX Cause This is correct. The output will always be labeled as an AO even thought the function of the output will be a DO Resolution If a DO is required for additional programming needs, create an internal DO point and use either a calculation or event sequence to control the new internal point.

Issue How can a TreeTech database be moved from one computer to another? Environment TreeTech - all versions Cause New pc purchase Resolution The project backups are stored in a "Jobs" folder.  The folder location in Windows 7 is:  C:\ProgramData\Schneider Electric\TreeTech\JOBS The folder location in Windows XP is:  C:\Documents and Settings\All Users\Schneider Electric\Jobs Use any compression utility to create a .zip or .rar of this folder.  Unzip the file in the destination computer in the same folder path.

Issue We want to be able to control the outputs on an I/O even if the I/O module is broken. Environment StruxureWare Building Operation I/O Modules   Cause The switches for manual override on the I/O modules needs power to be able to operate. Resolution The switches on the I/O modules that are used for manual override internally controls relays, that need to be powered to be able to operate.

Issue Unable to communicate to a PIM Environment Continuum version 1.9X and above. Cause Wrong PIM Type Resolution For a Schlage integration, the PIM required is the RSI version, not the VBB version, which is used for a Vanderbuild System.

Issue My NPR is flashing the LEDs from left to right, and I cannot get into the configuration editor. Environment NPR Cause It means the NPR is ready for a software restore. Resolution Once you load a bin file, you will be able to configure it.

Issue The TenantIndividual Report only returns the Hexadecimal format card number. Environment SevenReports Cause I/NET does not store the Decimal format of a Card number, on the Hexadecimal format. To view this information you will need to create a custom Report Field. Resolution In the SevenReports Design View, Right click on "SQL Expression Fields" and select "new" Name the Field Enter the following text: CONVERT(INT,CARDNUMBER) Save and Close Expand "SQL Expression Fields" Add the newly created Expression Field to your report Resize the Field to allow all of the data to be displayed Right Click on the Field select Format Field In the Number Tab Select "-1123" Click Ok Preview your report

Issue An  active video event will appear on the top of Video Monitor interface when there is an alarm triggered the video. But all the video events will  be gone when close the Video Monitor and you can't find any of the video events forever. Where does the video event list save? How can I find it to search and replay. Environment Continuum 1.91 above Cause It is a design Resolution For the video event list,  we never save it anywhere in the system, you can do search and replay with the active events only, not history events. there maybe some improvement about this  in the future version. By now, you can use an add-on application software, Continuum Video Inquiry to search the recorded videos according to the alarm event etc.

Issue Typically the master controller is at the end of the bus, but is it possible to place it in the middle? Environment AS b3 Cause Depending on the buildings wiring there could be a need to place the AS in the middle of the bus. Resolution The AS can be placed in the middle of the bus, but the terminating resistors must then be placed at both ends of the bus. This method wasn't officially tested in this manner by SQA, but it works similar to how a BCX 4040 does which can be placed in the middle of the bus in this fashion.

Issue What is the maximum number of lighting circuit relays that can be used on a 7780 controller? Environment 7780 Cause Configuration question Resolution 64 relays.

Issue After running a listview of Personnel records and sorting it by card number, the sort is incorrect. What is the proper procedure to sort Personnel records by Card number?

Create a workstation program named "Test1": (Example) Line Here1 Print "Hello There" Print PowerUpTime Stop Open the configuration and make it a fall thru program IMPORTANT check the "Run on any workstation box" The Run on any workstation required is what was changed from prior versions 2.Create another workstation program (Sample Program) Line There2 Run test1 to "c:\TestPEOut.txt" Goto There3 Line There3 If TS > 9 then Goto There2 Line E Stop

Issue Sigma - Delayed alarms. Environment Alarms Delayed alarms Cause When Sigma alarms are manually tested, they are displayed at the Sigma server normally. Sometimes, when an alarm occurs normally, this alarm is not displayed until other activities are carry out. Resolution This issue is caused by the Windows firewall. If the Sigma server is being used to communicate with the Sigma controllers, then the Firewall will be open, and any alarm messages from the Sigma controllers will pass through it and be displayed as normal. When the Sigma server is not being used, the Firewall will close, and no alarm messages will be allowed through. There are two options available; If the Sigma server is not connected to the Internet, then disable the Windows Firewall. Depending on the computer operating system the ways to achieve this will vary, but the help option will assist you in this process. The screen shot below shows an example on Windows XP.   The second option is to make an exception to the Firewall rules. This is achieved by opening the Windows Firewall, selecting "Exceptions", and choosing to "Add Port", the screen shot below demonstrates this. Please note that Sigma port 49152 is a UDP port number. The screen shot below shows this exception having been added.

Issue It appears the Dynamic DEMUX object in R2 - LonWorks jar - Conversions folder is not setting the output bits incorrectly for some SNVT_State values? Environment R2, all versions Cause Third party definition of the SNVT_State bits. Resolution The dynamicDEMUX object takes a "SNVT_State" value in and breaks it into representative output bits 0 to 15.  This object assigns the bits from bit0 to bit15 with bit0 on the left and counting left to right.  For example a SNVT_State value of 1000 hex is 1000000000000000 in binary, therefore the DEMUX object would show bit0 on.  Some third party manufacturers define their SNVT_State bits starting with bit15 on the left and counting down left to right ,so in this example their documentation would indicate bit15 should be on .  Once this is understood the DEMUX output bits can be interpreted correctly.

Issue Is it possible to include the Comments field from Extended Logs into Report Server Reports? Product Line EcoStruxure Building Operation Environment Building Operation Reports Server Cause Regardless of the new Reporting Features in EcoStruxure Building operation (EBO) 3.2, users of existing systems up to and including EBO 3.1 are asking if it is possible to include the Comments field in Extended Logs within the Enterprise Sever to enhance the data in RS Reports? Resolution Extended Log Comments within the ES are not available to Report Server reports today and given the move to new Reporting Features now available in EBO 3.2 it is unlikely that an Enhancement Request for such a feature would be implemented quickly. Therefore, the suggestion here would be to migrate the Extended Logs to External Storage via TimeScaleDB where all the Extended Log data (including the comments) can be freely manipulated by 3rd party Reporting Products.

Issue When the AS is connected to the ES we never have problems to login but sometimes when the AS have been disconnected from the ES it is not possible to login to the AS. 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 What is the easiest way to tell if a point is being exported due to alarm attachments or programs? Environment Listview Cause Run a quick report on which points are exporting data outside of the system. Resolution The easiest method to determine what points are exported is to run a listview of points and have the column "Export" in the listview. Every point that is being exported will have a "True" in the export column.
