Issue Chinese characters in TGML graphic become odd characters in WebStation, but display fine in WorkStation Product Line EcoStruxure Building Operation, TAC Vista Environment TAC Vista Webstation EcoStruxure Building Operation WebStation Chinese OS Cause The encoding method of WebStation is different from the one used in WorkStation. So the font of the Chinese characters should be changed. Resolution Change the Chinese character to Chinese font, like YouYuan or SimHei, etc, then it will work fine.

Issue Firewall issues when trying to reach out to the activation server for a license Product Line EcoStruxure Building Operation, Satchwell Sigma, TAC Vista Environment Building Operation Licensing Firewall Cause If the corporate network has a very restricted firewall policy or rules, the port needed to reach and activate a license may be blocked. Note: The same license server is used for EcoStruxure Building Operation, Satchwell Sigma and TAC Vista software licenses. Resolution Open Port 443 (HTTPS) for the server hosting the license server, and ensure that the routing paths to the Flexnet Licensing server URL's are all fully open. The Licensing Server URL should be opened from the site, and it is: https://schneider-electric.flexnetoperations.com If the site of the old server has issues with the non secure communications or the communications forwarding between the previous and the new server, there is a tool available to configure EBO to only use the new server. See the Exchange Community article for the download: SBO License Setup Note: From EBO V2.0 only the new license server is used, port 80 is no longer required and HTTP is redirected to HTTPS.

Issue How much ethernet bandwidth do lonworks systems consume using Loytec L-IPs, iLons, etc.? Environment TCP/IP ethernet network LNS System Cause IT professionals will sometimes hesitate to allow the control system to use the same TCP/IP network as the internet, phones, etc. They may ask what the expected bandwidth usage will be before granting access. Resolution It is impossible to explicitly state how much bandwidth a LonWorks system will consume on the ethernet. It depends heavily on the amount of LON traffic being sent by the controllers. The routers themselves do not produce traffic, they only pass the traffic onto and off of the ethernet. The traffic is created by the LON devices, Xenta controllers, Vista and LonMaker or other HMIs. Vista can create a maximum of 15 LON telegrams/second. This is very little traffic with respect to IP bandwidth. Unless you have made bindings into the LNS NI (which we never do in a Vista-scenario, since Vista cannot read these) there is basically nothing at all going out from LonMaker/LNS unless you are commissioning devices. Starting the LonMaker Browser also generates traffic. But this is also normally just in the design phase of the network, not in "operating mode". SNVT bindings or TAC network variables from one LON network to another over the IP channel also generate traffic. A typical Xenta can produce 2 SNVTs propagation/second and/or maybe 10 TACNV. This is not much (as IP-traffic), but if there are hundreds of nodes communicating simultaneously all passing through L-IP gateways, the amount of IP traffic will grow. If you are using a Loytec L-IP, it uses a protocol feature called "packet bunching". Before it sends out a packet on the IP side, it waits for an adjustable time (Aggregation Time, default = 16ms) if some packets are following, which have to be sent to the same IP addresses. If some packets are following, it puts the packets in the same IP frame and sends it all together in a single IP packet. The receiving node unpacks it and makes multiple EIA-709 (Lonworks) packets again.

Issue Missing Admin user password for the Loytec L-Gate Universal Gateway or LIP router. Product Line TAC Vista Environment L-Gate Universal Gateway LIP Cause Forgot the default admin password. Resolution The default login for L-Gate and the NEW style LIP (blue-grey in color) is: Username: admin Password: loytec4u The default login for OLD style LIP (off-white in color) is: Username: admin Password: admin

Issue Time schedules are not switching off according to the workstation time. Time schedules are delayed. Product Line TAC Vista Environment TAC Vista, Xenta Servers and Controllers (280/300/400) Cause The Time in the TAC Xenta 911 and TAC Xenta controller is not the same as in TAC Vista Server. Resolution To check the time in the TAC Xenta controller follow these steps : Browse to the TAC Xenta controller Right Click on the controller and select Properties Select the Information Tab. This will display the time in the TAC Xenta controller To check the time zone of the TAC Xenta controller select the time settings Tab. Once the TAC Xenta controllers have been set in the right time zone TAC Vista server will sync them to the correct time. By default this occurs every 10 minutes The final step is to ensure the time and time zone of TAC Vista server is correct. To do that locate your TAC Vista Server object and right click then select properties. Select the Information Tab to show the server time. This time is governed by the PC time so to adjust the PC time through Windows.

Issue Controller and graphic names in Vista Workstation are red, italicized. Product Line TAC Vista Environment Vista Workstation Cause A red, italicized controller or graphic name indicates that this Vista object has been "checked out." During a partial Vista database export, there is an option for whether or not to indicate the item has been checked out. This can be used if multiple people are working on a single server from several engineering locations to prevent overlap. Resolution To restore the database: Import the original export .zip file. If you do not have this file, you can also right click on what you want to return to normal and select "Undo Check Out."

Issue Error: "Could not load file or assembly 'vjslib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified." when starting TGML editor Can not start TGML editor. Product Line TAC Vista Environment TAC Graphics TGML editor Cause TGML editor needs Microsoft Visual J#® 2.0 Redistributable Package to be installed on the machine for the TGML editor to run. If this for some reason is missing it needs to be installed. Resolution Go to the following link http://www.microsoft.com/downloads/en/confirmation.aspx?FamilyID=e9d87f37-2adc-4c32-95b3-b5e3a21bab2c Download and install the program

Issue A floating-point value is displayed incorrectly in a TGML graphic. The presentation field appears to show random numbers. The example shows how the value 11.60 is represented in a TGML graphic. 11.60 is actually stored as 11.600000381469727. In format presentation mode: In none presentation mode: The last 6 digits of the stored floating-point value are seen! Product Line TAC Vista Environment TAC Vista 5.1.X TGML editor 5.1.X A presentation text bound to a floating-point value. Cause Vista uses the PC's default settings for number of decimals, when presenting values in TGML graphics. Resolution To resolve the issue, either set the format property to "Presentation" for the binding object or change the PC's settings to view fewer decimal places eg. 2.

Issue When TAC Vista is setup as an OPC Server, Can you access the Historical Data (HDA) from TAC Vista SQL DB Product Line TAC Vista Environment TAC Vista OPC Server OPC Client Cause When TAC Vista is acting as an OPC Server and providing integration with a third party software / device, online and alarm values are all that is supported. Historical data is not supported via the OPC interface. Resolution It is not possible to access the historical data from the Vista SQL database, when using Vista's OPC Server . It may be possible to get historical data with the help of some third party OPC-HDA-Server for SQL software. This option has not been tested, and issues related to this interface are also not supported. Click on below link to see an example of OPC-HDA Server for SQL. http://www.opcti.com/OPC-HDA-Server-for-SQL.aspx

Issue TAC Vista appears to keep trying to retrieve logs from controllers despite them being offline. This causes a lot of event messages to be created and fills up the log database quicker. Product Line TAC Vista Environment TAC Vista 5.X Older RPU (remote processing unit) under a PLB ( 5751), containing logs to be retrieved by Vista. Cause TAC Vista appears to keep trying to retrieve logs from controllers despite them being offline. This causes a lot of event messages to be created and fills up the log database quicker. Resolution Vista continues cyclically trying to retrieve the log/s even when the RPU under the PLB is offline.

Issue How to back up a full version of SQL (not express)? Product Line TAC Vista Environment SQL 2005, 2008 full versions, i.e. Enterprise, Standard etc. TAC Vista 5.1.X Cause A customer may wish to backup the TAC Vista log database to prevent data loss if the SQL server crashes. Resolution There are 2 options available, depending on the TAC Vista SQL configuration the customer has configured. If the customer has selected "Typical" on the TAC Vista Server setup "SQL" tab, you can configure this through Vista workstation. Right-click on the Server object in Workstation and select "Properties". Select the "Log Backup" tab and configure the backup schedule there. If the customer has selected "Custom" on the TAC Vista Server Setup "SQL" tab, this can be configured through SQL Management Studio (which is free to download from Microsoft, if the customer doesn't already have it). Start SQL Management Studio and connect to the SQL server instance that is being used for TAC Vista. Expand the SQL server in the tree (in SQL Management Studio) and locate the "Management" folder. Expand that folder and locate the "Maintenance Plans" folder. Right-click on the folder and either select "Maintenance Plan Wizard" or "New Maintenance Plan". Configure as required.

Issue By default, you are not allowed to shut down/restart the TACLIC/TAC License server when logging in to the Flexnet license admin web application from another PC than local. Product Line TAC Vista Environment TAC Vista versions 5.1.8 and higher, using the web-based TACLIC tool. Cause A remote shutdown/restart is required when adding/removing/editing license files in the License Files folder. Resolution The following steps should be done on the PC where the license server is located: In the "server.xml" file located in the "conf" catalogue (...\License Server\conf), edit the following string from " stopServerRemoteAllowed="false" " to " stopServerRemoteAllowed="true" " Then save the file and restart the license server. The setting can also easily be changed using the tool called "TACLicenseServer Settings."

Issue Is it possible to save a copy of a TGML graphic in a standard format such as jpeg, bmp etc? Product Line TAC Vista Environment TGML graphics editor 5.1.X Cause For documentation purposes a customer may wish to have an image of a TGML graphic, perhaps in a system reference guide, with explanatory text. Resolution Open the graphic in TGML graphic editor. Select "Export..." from the file menu and then select the file format in the dialogue that appears.

Issue Specific Trend log stops working in TAC Xenta Get estimated values in some trend logs; others are working Trend log is not retrieved from TAC Xenta Product Line TAC Vista Environment TAC Xenta 301 TAC Xenta 302 TAC Xenta 401 TAC Xenta 282 TAC Xenta 283 TAC Vista Cause The issue can be that there is a "Non value" in the log. For example, if you are logging an expression block with division in it and there is a division by 0. This seems to lock the trend in TAC Vista, and no other values can be collected. Resolution In the properties for the log, click on erase log. This will delete all values in the device. Open your menta and make sure that there is no possibility of division by 0.

Issue Checking if a port is open Product Line Andover Continuum, EcoStruxure Building Expert, EcoStruxure Building Operation, Field Devices, Pelco, Satchwell MicroNet, Satchwell Sigma, TAC IA Series, TAC INET, TAC Vista Environment TCP/IP Communication Command Prompt Telnet Command Cause Suspect certain network ports are blocked and need to verify Resolution It is possible to check if a port is open in a network by issuing the Telnet command. Note:- Telnet operates using the TCP protocol. UDP connectivity cannot be tested using Telnet. If a port is open, a blank screen will be seen after issuing the command: telnet [domainname or ip] [port] where [domainname or ip] is the domain name or IP address of the server being checked [port] is the port number the server application is listening on For example: telnet 192.168.0.20 9001 (to a closed port would display a connect failed message) telnet 192.168.0.20 9003 (to an open port would display a blank screen) To exit the Telnet session, type Ctrl + ] and then type "quit". For how to enable Telnet in Windows 7 please see Enable Telnet Client on a Windows 7 PC

Issue How to use the Telnet command to troubleshoot network connectivity and check for blocked network ports. Product Line TAC INET, TAC Vista, Andover Continuum, Satchwell MicroNet, Satchwell Sigma, TAC IA Series, Field Devices, EcoStruxure Building Operation, Other, Pelco, EcoStruxure Building Expert, Access Expert, Security Expert Environment TCP/IP Communication Command Prompt Telnet Command Cause Suspect certain network ports are blocked and need to verify Resolution Note:- Telnet operates using the TCP protocol. UDP connectivity cannot be tested using Telnet.

Issue TAC Vista reports an error in the Alarm view that no more threads can be created and remote workstations cannot connect to the Vista server. Product Line TAC Vista Environment TAC Vista Workstation Cause This issue occurs when the TAC Vista remote computer that connects to the TAC Vista Server computer is left logged in and the Remote computer goes into hibernation. This causes the TCP/IP Thread between the TAC Vista remote computer and the TAC Vista server PC's to remain in use. Then once the TAC Vista remote computer is taken out of hibernation another TCP/IP Thread is created. Eventually this will use up the allocated thread count and generate an error. Resolution Restarting the TAC Vista Server PC will fix the issue until the TCP/IP Thread count increase to the limit again. The TAC Vista Remote Workstation computer can be setup so it doesn't go into hibernation and remains on, then the TAC Vista log off function works correctly and closes down the TCP/IP Thread. Alternatively change the TAC Vista Remote Workstations to TAC Vista Servers and configure them to look at the mastern TAC Vista server. This configuration uses a different communication setup for Server to Server communications. See the Creating TAC Vista multi-server network Knowledge Base article for further information on this configuration

Issue Not possible to get a Xenta Server / 911 online in TAC Vista. It is possible to ping it and connect to it via a Web browser using ports 443, 80, and Port 1068 is open, but it is not possible to get online in Vista. Product Line TAC Vista Server Environment TAC Vista TAC Xenta 911 TAC Xenta Server Cause The problem, in this case, was that another Vista server was connected to the Xenta Server / 911. This could have been from a technician or the customer who started Vista with this database loaded and had the device online in their Database. The Xenta Server / 911 will only communicate with one Vista Server at a time and will close the connection if another Vista tries to communicate with it. Using Wireshark it is possible to monitor this scenario as shown below: Packet number 57439: Vista is trying to establish communication with the Xenta Server or 911( sending an SYN). Packet number 57440: The Xenta sends an acknowledgment on the SYN from Vista, but with the window size set to zero, this is because the Xenta can't buffer information as a computer does. Packet number 57441: Vista sends an acknowledgment on the message from the Xenta Packet number 57448: The Xenta sets the correct window size. Packet number 57449: Vista starts to communicate Packet number 57452: The Xenta closes the communication to the Vista server Resolution Ensure only one Vista server is started when the Xenta server / 911 is included in the database.

Issue TAC Vista database export/import. Description texts are missing when the .zip file is imported. Product Line TAC Vista Environment TAC Vista Server TAC Vista Workstation Export/Import Cause Changes to the object description text fields made in TAC Vista Workstation are not automatically saved in the .mta file. Resolution To make sure that the description texts will be included in a database export (physical structure only): Edit the Xenta application with text description fields added or modified through Workstation. Save the Xenta application to the database. If you do this, the description text will be written in the .mta file and will be included in a database export.
