Issue Do not get any values in webstation Bindings in TGML do not work Environment Vista Cyrillic Cause If bindings in TGML contain Cyrillic characters and the operating system installed is set to a language that can not handle Cyrillic (i.e English), the bindings will not show their values. Resolution Set the region and language settings all to the desired language, i.e Russian or Polish. Be sure Webstation is set to handle the language by installing the correct language pack. Edit the TGML and make a small change so you can save again, this time the Cyrillic letters will be understood by Tacos.

Issue The SNVT bindings break after replacing a VT6700 Viconic thermostat with a VT7600r, VR76_PIR, SE7600, etc. Environment LonMaker NL220 Schneider Electric SE76XX stats Cause The older VT7600 Viconic thermostat includes the nvoOAT SNVT. On the newer models of the Viconic stats the nvoOAT variable is no longer available. The removal of the nvoOAT variable causes the SNVT table to become unaligned and breaks the existing bindings that had been created. Resolution When replacing a VT7600 thermostat with any new Viconics model the existing SNVT bindings will be broken. It is important to make note of all bindings made to the stat before performing a replace with a newer stat.

Issue What type of sensor element is used in the STR300? Environment STR300 Cause The HVAC European+Sensors+Catalogue.pdf on the Extranet, as well as the datasheet for the STR300 Series says that the sensor element is PT100 Class B. Resolution The actual sensor element for the STR300 that are made today is NTC Thermistor 10 kOhm. The output from the STR300 is 4-20 mA.   The documentation will be updated shortly.

Issue Could the L-VIS screen be manage even if the operator is using latex gloves? Environment Loytec L-VIS Cause The screen used on Loytec L-VIS is resistive, and due to that can be managed with latex gloves. Resolution The screen used on Loytec L-VIS is of resistive type, and due to that can be managed with latex gloves.

Issue Trend log values from two or more M-bus meters under a Xenta Server are intermittently mixed up, also when viewing a trend log page in the Xenta Server's web interface. Values from meter 1 are (sometimes) logged in meter 2's trend log and/or vice versa. Environment Xenta 913 Xenta 701 Xenta 711 Xenta 721 Xenta 731 M-bus meter Cause When secondary addressing is used for the meters, there is an extra telegram sent from the Xenta Server before asking for the actual values/data. The M-bus meters then replies to this telegram so that the Xenta Server knows which secondary address belongs to which meter. In some cases (only seen with a few meters) these addresses seems to be intermittently mixed up and this will cause the issue described above.  Resolution Use primary addressing for the M-bus meters.

Issue Manually add individual components to a Component Library Environment TGML Graphics Editor Cause Components are sometimes stored as a file type TGMLCOMPONENT File with the extension .tgmlcomponent file. Resolution Open the Graphics Editor and Select a Component Category you wish to add components to Open Windows Explorer and browse to the .tgmlcomponent files. Drag the file(s) from Windows Explorer to the the TGML Graphics Editor Component Category window. Click OK or press enter to acknowledge each file as it is added.

Issue When using the SmartStruxure Interface, is it necessary to configure any DCOM or firewall settings to run TAC Vista and SmartStruxure on different computers? What protocol is used for communication between the SmartStruxure interface for TAC Vista and the ES? Product Line EcoStruxure Building Operation, TAC Vista Environment TAC Vista server TAC Vista SmartStruxure Interface SmartStruxure Enterprise Server (ES) Cause Communication issues between interface and SBO Resolution Only HTTP/HTTPS are used. You can configure the interface to use only one of the protocols. You can also configure what ports to use.

Issue Is it possible to use the TAC Xenta 110-D device with room unit STR150? Environment STR150 TAC Xenta 110-D Cause It is not possible to use STR150 together with the TAC Xenta 110-D device. Resolution TAC Xenta 110-D does not support STR150.

Issue Values in graphics from Xenta and Lon devices under a Xenta 911 network are not updated. Some values show database values and some values are showed with red crosses. When clicking on the value in the graphic the value is shown correct.  Environment TAC Vista 5.9 with a Xenta 911 as Lon network interface. Cause This could happen if many Lon and Xenta devices under the Xenta 911 is offline. When Vista do a online poll for a Xenta or Lon device and don't get a reply the communication will be halted for 3 seconds because of retransmission and time outs. This would not be a problem if a Loytec interface was used as it can handle more then one communication thread at the time but the Xenta 911 only use one communication thread. In this case it is possible to see the correct value when clicking on it in the graphic as that is a user command with much higher priority than updating values in a graphic have. Resolution Try to minimize the number of offline devices which reside under a Xenta 911 network in the Vista database as these devices will slow down the communication on the Lon network.  

Issue TAC Menta could give mainloop overrun then having an application with many Alarm blocks and more than one ERR block. Environment TAC Xenta 280/300/401 TAC Menta Cause When the ERR block is executed, it goes through all Alarm blocks to check status, having more than one ERR block makes this loop to be run more than once. Resolution There sould be a maximum of one ERR block per application.

Issue The customer wants to have a binding and transfer a value, but also wants to have backup set on the receiving variable in the TAC Xenta device. Environment TAC Vista TAC Xenta 280/300/401 Cause Setting the Backup flag will make the variable be written into the flash memory every time the value is written. Doing this on a value that is regularly transferred will damage the flash memory, as it has to write all the time. Resolution The Backup flag should not be set on variables that are written to on a regular basis.

Issue On a Windows 2003 Server or Windows XP, TAC Vista is not able to locate the license server, even though everything seems to be set up correctly. You get the message "-15, 10 System Error: 10061 Winsock Connection Refused" when you try to open any TAC Vista software. Environment TAC Vista Flexnet license Windows 2003 Windows XP Cause The TAC Vista software is looking for the license server on the PC defined, but the license server is running using the TCP/IP v6 address and the software doesn't support that on this operating system. Resolution Uninstall TCP/IP version 6 and reboot the PC.

Issue Selection and installation of a pulsed output module. Product Line Andover Continuum, EcoStruxure Building Operation, Field Devices, Satchwell Sigma, TAC Vista Environment Heat Meter Multical 602 Pulsed output module No pulses Cause Installed card does not give output pulses. Resolution Selection of the output card. The Schneider Electric part number is MAPULSETOPC and this is the equivalent to Kamstrup part number 602-0C This card will provide 2 pulse outputs for energy and volume, CE and CV respectively. Normally, energy (CE) is connected to 16-17 and volume (CV) to 18-19, but other combinations can be selected via the PC program METERTOOL, also used to select pulse duration 32 or 100 ms. The MAPULSETOPC is actually a top module, which means that it is fitted into the top piece of the MC602 calculator, basically the inside LCD cover. This is released by pressing downwards in the middle of the plastic piece on the left, and at the same time pushing the top module towards the left.

Issue In the TAC Xenta 151-D, the nvoAlarmStatus handles the test of the dampers, but the translation of the status is not documented Environment TAC Xenta 151-D Cause nvoAlarmStatusis used to report the actual status of the fire damper tests. Resolution nvoAlarmStatus is a SNVT_state with the use of the following bits: nvoAlarmStatus.bit0 = 1   OBJECT1_CLOSE_TIME_TOO_LONG    nvoAlarmStatus.bit1 = 1   OBJECT1_CLOSE_TIME_TOO_SHORT   nvoAlarmStatus.bit2 = 1   OBJECT1_OPEN_TIME_TOO_LONG     nvoAlarmStatus.bit3 = 1   OBJECT1_OPEN_TIME_TOO_SHORT    nvoAlarmStatus.bit4 = 1   OBJECT2_CLOSE_TIME_TOO_LONG    nvoAlarmStatus.bit5 = 1   OBJECT2_CLOSE_TIME_TOO_SHORT   nvoAlarmStatus.bit6 = 1   OBJECT2_OPEN_TIME_TOO_LONG     nvoAlarmStatus.bit7 = 1   OBJECT2_OPEN_TIME_TOO_SHORT    nvoAlarmStatus.bit8 = 1   OBJECT1_SET_CLOSE_TIME_FAILED nvoAlarmStatus.bit9 = 1   OBJECT1_SET_SELFTEST_OK        nvoAlarmStatus.bit10 = 1  OBJECT1_SET_SELFTEST_FAILED    nvoAlarmStatus.bit11 = 1  OBJECT2_SET_CLOSE_TIME_FAILED nvoAlarmStatus.bit12 = 1  OBJECT2_SET_SELFTEST_OK        nvoAlarmStatus.bit13 = 1  OBJECT2_SET_SELFTEST_FAILED     

Issue It is desired to configure a minimum off time, so when the compressor stops in e.g. heating mode, it will not start again before a minimum time has elapsed in the same mode. This setting is not available in the device. Environment TAC Xenta 121-HP Cause There is no setting for minimum stop time when in the same mode, there is only a minimum stop time between modes. Resolution As a workaround, set the "Activate at" value to something other than zero (say 10%), so that you can use the "Hysteresis" at 10%, and this way get a delay. This way you will get a delay in the most cases, a little time before the controller reacts.

Issue Why isn't the OpenLNS a full, un-limited license? Environment OpenLNS OpenLNS CT Cause Renewing OpenLNS CT Annual Maintenance You can renew your annual maintenance for OpenLNS Server and OpenLNS CT before they expire. Renewing your OpenLNS and OpenLNS CT annual maintenance enables you to continue installing software updates and upgrades. If you do not renew the products’ maintenance, you can still use the products; however, you will not be able to upgrade it with updates or upgrades released after your annual maintenance expired. You cannot renew your annual maintenance after it has expired. Once it has expired, you must purchase a new activation key to be able to install any updates or upgrades released after your maintenance expired. To renew your annual maintenance, purchase an OpenLNS Commissioning Tool Professional One-Year Maintenance Renewal (Echelon model number 93800) or an OpenLNS Commissioning Tool Standard One-Year Maintenance Renewal (Echelon model number 93810). Echelon will process your order, and your maintenance coverage will be extended so that you can continue updating and upgrading OpenLNS and OpenLNS CT for an additional year. Resolution If paying the annual maintenance fee, you have access to updates and upgrades. Not paying still means that the program could be used, however it could not be updated with the latest patches.

Issue TAC Xenta I/O modules that are added as LonWorks units in TAC Vista, are converted to Xenta I/O modules belonging to a Xenta Base unit (SlaveSpeak devices) in EcoStruxure Building Operation, after conversion using TAC Vista Conversion Tool. Product Line EcoStruxure Building Operation, TAC Vista Environment Vista Server TAC Vista Conversion tool Xenta Xenta I/O-modules Cause In TAC Vista, the Xenta I/O modules are normally located on the same subnet as the Xenta Base unit, and belong to the Xenta Base unit, communicating as SlaveSpeak devices. If a Xenta I/O module is located on another subnet than the Xenta base unit, it could instead be added as a LonWorks Unit in Vista, and therefore communicating via LonWorks bindings to the Xenta base unit using SNVTs. Vista Conversion Tool does not handle this configuration. In the conversion tool, all Xenta I/O modules are expected to be connected directly to a Xenta base unit, located on the same Subnet, and are therefore always treated as SlaveSpeak devices. Resolution After running the Vista Conversion tool, you have to re-build the LonWorks Bindings between the Xenta I/O module and the Xenta Base unit manually in EBO, as the Conversion Tool does not handle the actual configuration setup.
