Perform a station save and attempt to upload the controller again. Repeat this process if necessary.

Issue Various problems with converted TGML graphics Bindings of the I/NET objects within Building Operations have wrong and / or illegal point address. Environment I/NET integration with SmartStruxure Cause Improper preparation before converting graphics may cause nuisance issues. Resolution Ensure the following is done when converting a sites I/NET graphics to TGML Before converting the graphics to TGML Ensure all save files are current Ensure the I/NET network configuration is current Before importing the graphics to StruxureWare Ensure that all affected controllers are imported.  Do not change any names or descriptions before importing graphics Upload any controller which indicates it is required. This will ensure that point names for graphic bindings are correct. In the INET Interface path box, enter the path to where the INET interface is located in WorkStation. This setting affects the bindings that get defined for objects in the resulting TGML file(s). If you accepted the default name when you created the I/NET interface in WorkStation, this path is typically /Server 1/INET Interface/.  Make sure this matches the installed system details.   Click Here to get more detail from the Online Web Help.

Now add the automation server underneath the enterprise server.

Issue Host conflict window always pops up, and cleaning routing table doesn't help. Product Line EcoStruxure Building Operation, TAC INET Environment I/NET Cause Host conflict is a normal issue happening in I/NET. It is usually caused by the duplicated host ID setting on different servers, or an engineer laptop is inserted into the network with the same host ID setting with some server. And the routing table will be messed up since all the IP related information will be recorded in the routing table and it will be distributed to all the network devices, including all the servers and NPRs. The usual solution is to clear all the routing tables on all the network devices, . Refer to How to Remove the Routing Tables in a Device or PC about how to clear the routing tables. But if the routing table is cross referred, like Server 1 adding NPR 1 and NPR 2 as reference hosts, while NPR1 adding Server 1 and NPR 2 as reference host, the routing table will never be cleaned out since when you clean the routing table for Server 1, NPR1 and NPR 2 will still try to send their wrong routing table to Server 1. Unless all the network devices are disconnected and the routing tables are cleaned one by one, or disable the 50069 port for the whole network, which is used by the communication between network devices, there is no other way to clean them out. And these two method are not applicable sometimes. Resolution If the routing table can be managed well, such kind of issue will never happen. The best practice on adding reference host and creating routing table is: On the servers: Choose one server as the master reference host. All the other servers add this server as reference host. Don't add NPR as reference host. All the NPRs can be added into the master server by clicking on the NPR button in I/NET configuration and added one by one manually. By this way, the master server can build its own routing table without impacted by other devices. And this one is the only routing table in the whole network. On NPRs. If NPR doesn't need to talk to other NPRs, like transferring indirect points, there is no need to add reference host for NPR. If indirect points are needed, just add the master server as the reference host. Then this NPR will be able to see all the other NPRs based on the routing table on the master server. If the master server is not equipped with UPS, or not always promises to be online, another master NPR can be chosen as a secondary reference host. Add this NPR as a reference host to all the servers and other NPRs. Under this scenario. if the routing table needs to be cleaned, only the master server and the secondary reference host need to be cleaned. It will be more easier to clean all the routing table and get rid of the host conflict error.

Issue When I/NET is running under Windows 7, there will be a display issue about alignment. The font size has been changed to smaller - 100%, but still no use.  Product Line EcoStruxure Building Operation, TAC INET Environment Windows 7 Cause Be sure to try I/NET Seven Windows fields not aligning correctly on workstation's display to change the font size first to see whether it can help. If not, continue to the next information. I/NET used the default MS Sans Serif font to display everything. But something has changed in Windows 7 about the font display.  Research showed that many users with high resolution monitors (particularly LCD flat screens) were running the monitors at lower resolutions than the native resolution of the screen. This was usually because at the native resolution, the fonts were becoming too small to read, so the users would decrease the resolution. Windows includes a facility to increase font and window sizes while keeping the screen at the native resolution.  This is a much better method of increasing the font size as it can produce much smoother images by using many more, smaller pixels. The really significant issue is, unlike CRT monitors, flat-panel LCD monitors have a fixed pixel size, or "resolution", and that when users change to a lower resolution (in order to increase text size) the system has to re-sample the lower-resolution display image into its fixed resolution causing a significant degradation in display quality: not just text looks worse, everything looks worse. A change was made for Windows 7, to set the screen resolution to the monitor's native resolution and if the screen is over a certain resolution to default the font size 120 DPI (dots per inch). This is approximately 125% of normal 96 DPI (100%). When the system defaults to 125% DPI it also adjusts the MS Sans Serif font to be bigger.  If the user then decides to set the DPI back to 100%, then TrueType fonts, which are scalable, adjust as expected. But the bitmap MS Sans Serif font does not: it remains at the larger size, hence this issue. This problem does not occur if Windows 7 keeps DPI at 100% when it is first installed. So anyway, when the default font size is Medium - 125% instead of smaller - 100%, probably the solution below is needed to solve it. Resolution Go to the Registry Editor, and find HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts. Find the entry MS Sans Serif 8,10,12,14,18,24. The original value is set to SSERIFF.FON on a system which started at 125% DPI. Set to SSERIFE.FON on a system which started at 100% DPI.  Notice that one character of the file name changes from F to E. Restart the computer, and make sure the font size is set to smaller - 100%. Refer to I/NET Seven Windows fields not aligning correctly on workstation's display about how to set font size. Then it should go back to work.

Issue Alarms being generated in I/Net are not showing up on the Enterprise Server. Product Line EcoStruxure Building Operation, TAC INET Environment SmartStruxure Integration with I/Net Alarms Cause Alarms generated in I/Net are not populating on the Alarms Window on the ES, all masking are set on both the AMT Configuration and Host Masks. When the point goes into Alarm, it populates the Alarm Window type, whether it is Priority or Critical with said point address. However, it does not show up on the Alarms page because the bin files on the controller needs to be updated to the latest version of software and all points need to be saved prior to integrating with SmartStruxure. Resolution When integrating with SmartStruxure, all controllers are supposed to be updated with the latest version of software as well as sav files, per Resetting a 7793 Controller and PCU (Applies to 7793, 7716, 7728, 7756). Once completed, recheck the points by putting them in Test mode so that they can generate the Alarm condition and it should show up in the ES Alarm now.

Issue The TGML page is dynamic but looks static. Product Line EcoStruxure Building Operation, TAC Vista Environment Vista StruxureWare Interface Cause In the Release Note, page 30 says: It is possible to navigate to a TAC Vista Webstation TGML Graphic through a link in a SmartStruxure TGML Graphic. To achieve this connection a link object is created in the SmartStruxure TGML Graphic which is linked to a SmartStruxure hyperlink object that holds the TAC Vista Webstation TGML Graphic page address. Example of a hyperlink objects address in SmartStruxure that is linked to a TGML Graphic in TAC Vista: HTTP://ip_address/webstation/LoginPage.aspx?page=TgmlGraphicsPage.aspx?objectId=3074949137 Note: This will always require a login by a valid TAC Vista user, even if the TAC Vista Webstation auto login feature has been activated. Resolution The example link above is referring to a static page. For example, if the TGML page is dynamic, you will see the following in the copied link (see bold). HTTP://ip_address/webstation/LoginPage.aspx?page=TgmldynamicGraphicsPage.aspx?objectId=3074949137 You can also read the following in the release note: In order to determine the TAC Vista Webstation URL for a TAC Vista Webstation TGML Graphic the following TAC Vista Web Setting configuration must be in place: Optimized TGML Loading is deactivated Folders pane is set to Standard HTML With these settings it is possible to right-click a TGML object in the folders pane and select "Copy Shortcut." This will copy the TAC Vista Webstation URL to the clipboard and it can then be pasted into a SmartStruxure hyperlink object address field. After the shortcut has been pasted, it will have to be modified in order for the TAC Vista TGML Graphic to be displayed properly in SmartStruxure. The modification is marked with bold in the example below: Copied: HTTP://ip_address/webstation/TgmlGraphicsPage.aspx?objectId=3074949137 Modified: HTTP://ip_address/webstation/TgmlGraphicsPage.aspx?objectId=3074949137 If the link you copied was a dynamic TGML the link will look like: HTTP://ip_address/webstation/TgmldynamicGraphicsPage.aspx?objectId=3074949137 and should be modified as this HTTP://ip_address/webstation/LoginPage.aspx?page=TgmldynamicGraphicsPage.aspx?objectId=3074949137 Also reference the TAC Vista Webstation Graphics Links and SmartStruxure Integration tool on the Community.

Issue How to check the amount of used memory in a TAC Menta/TAC Xenta application. Product Line TAC Vista Environment TAC Menta Xenta 281 Xenta 301 Xenta 401 Cause When programming applications for TAC Xenta, you may want to be able to check the size of your application, to verify that it can be downloaded to the device. Resolution To be able to check how much memory an application is using, the application needs to generated. In TAC Menta, edit mode: Select Option, Simulate to enter Simulate mode. In Simulate Mode, select Commands, Generate, to generate the application. To be able to check the Memory usage, you have to return to Edit mode, Select Options, Edit. Now you can check the Memory usage by selecting Options, Memory Usage...

Issue In order to make page links between different I/NET graphic folders work fine, the same folder structure needs to be created manually in EcoStruxure / SmartStruxure. Refer to Converting I/NET graphics to TGML using the "Create Source Tree" option to realize this. Product Line EcoStruxure Building Operation, TAC INET Environment EcoStruxure / SmartStruxure 1.4 or higher I/NET Cause The I/NET graphic folder structure will not be created automatically before SmartStruxure 1.4.0. Resolution Starting in version 1.4.0, there was a new feature called Data import for I/NET graphic. Using this feature, all the converted I/NET graphic folders structure can be imported at one time without any need for manual work. Here are the steps to make it work: Convert the I/NET graphics according to Converting I/NET graphics to TGML using the "Create Source Tree" option, but do not create the folder structure manually in EcoStruxure / SmartStruxure. Create the default Inet Graphics folder by right clicking on I/NET Interface-->New. Right click on Data Import and choose the root folder of all of the I/NET graphics. Click OK. Data importer will check all the file names and bindings. If any error happens, check and fix it before importing again. (Currently apostrophe is not supported in SmartStruxure. Change the name and relative link and do it again. It may be fixed in later version) Check whether all the bindings and links work fine. Important: Currently this feature doesn't support export/import in SmartStruxure. It will fail to import if any sub folders are contained under INET interface. This may be fixed in later version. The workaround is to still create the whole structure according to Converting I/NET graphics to TGML using the "Create Source Tree" option.
