Issue Unable to select DVR when selecting Video source device in Video Object control in a Pinpoint Graphic. Environment Continuum Cyberstation Pinpoint Graphics Endura DVR Cause The Video Object control in Pinpoint is not able to have an external DVR as the source. It is only able to show images from internal cameras connected to the Workstation such as by USB or the older Integral Flashbus card.   Resolution The Video Object control only supports cameras connected to the Cyberstation through the means of USB or an Integral Flashbus card. Alternatively, there are two options available to show video from an external DVR/camera in a Pinpoint Graphic. Configure a VideoLayout or Video Monitor object and link this to the DVR and camera you wish to view. Create a button on the graphic to launch the required camera. If the camera is an IP camera and supports streaming, use the embedded Webpage control on the Pinpoint graphic to link to the webpage streaming the camera image. Note: This is a resource heavy way of displaying video in Cyberstation and isn't recommended. The integration that is offered to Endura or Digital Sentry are the best solutions for displaying video in Cyberstation.

Issue How do integrate an Xenta 913 in Vista? Do I need to give an IP address as well as a Neuron ID to integrate an Xenta 913 in Vista? Environment Vista 5.1.X Xenta Server 913 (applies to other models) Cause There may be some confusion as to whether an Xenta 913 is considered a LON device or IP gateway in Vista. Resolution If the device is being used as a Modbus\M-bus\C-bus\BACnet client only the IP address is required. In Vista workstation, right-click on the Server object and select New\Device\Xenta Server 913. Give the device a suitable name. Right-click on the device and select Properties. Set the IP address for the device. Right-click on the device and select edit. Configure the device in TAC XBuilder.

Issue Replacement of the 7801 TAP. Product Line TAC INET Environment I/NET site with TAP configuration Cause Desire to upgrade or replace the old TAP configuration Resolution First of all, perform a good backup of the existing site. 7770, 7771, 7797, 7801 TAP replacement hardware explains the replacement of several TAP hardware devices. If the site has a 7801 TAP, the Xenta 527 would be a replacement choice. In I/O server instead of Link Type being Direct, it should be None. Then Enable the TCP/IP and put in the credentials for the Xenta 527. In Network Config, save Xenta 527 link Penetrate and save all below the Xenta 527 to DB Configure Host Mask for Host computer, as well as Xenta 527 The site technicians will need to follow the TCONs and manuals for the Xenta to Host pc, including the wiring and Host Computer configuration, and network connection. This is clearly explained. Also, for the sub controllers, Connect to the controller one at a time Select Edit, Controller, Configuration In the Distribution Parameters section, change the selection from Reliable Tap to None. Reset that controller by cycling power or pressing RED reset button Check the transactions window of AMT to ensure events coming in The site engineers/technicians will need to take time and looking through the material and changing out the TAP with a Xenta requires time and concentration so that it is a smooth transition. 

Issue When upgrading Vista Workstation to version 5.1.6, each Xenta Servers' properties should be set to XBuilder version 5.1.6. Then by right-clicking and selecting "Edit," that project will be opened and upgraded. However, if another projects network has been browsed in, it will ask you to please upgrade that project before continuing. If two Xenta Servers are each browsed into each other's networks, then it will not allow you to upgrade either of them. In previous versions, this was allowed, but with changes to 5.1.6 it is not possible to bypass this warning. Environment Vista Workstation 5.1.6 and above Xenta Server Xenta 511, 527, 701, 711, 721, 731, 913 Cause All Xenta Servers passing data between each other should be the same version. In the past, this fact was made optional, but with the release of 5.1.6 a check on the source file requires that they match. Resolution This requirement is only true of true Xenta Servers in a Vista system. Stand-alone XBuilder projects do not have this same check. To bypass the warning: Go to Start > Programs > Schneider Electric > TAC Tools 5.1.6 > XBuilder This will open XBuilder 5.1.6 in a stand alone mode (not from Vista Workstation) Go to File > Open Project and browse to the first Xenta Server's XBuilder project file folder and double click the .xbp515 project file The XBuilder project will be upgraded to 5.1.6. The other project's network will still be 5.1.5, but this is allowed in the stand alone mode. File > Save will save the .xbp516 file to the hard drive. Go back to Vista Workstation, right click and edit the second Xenta Server's XBuilder project and it will not upgrade and can be saved to the Vista database and to the hard drive. The first Xenta Server can now also be upgraded.

Issue Changing the LON device's subnet and node address. Environment I/A Series G3 LonWorks Integration Cause When a LON device is added to the station database, its subnet and node addresses are automatically assigned. For the correct communication to be established there may be a need to change the subnet / node address of the LON device. Resolution To change the device subnet / node address: Right click on the LonNetwork and go to the Lon Device Manager. Select the LON device for which subnet / node address needs to be changed Edit the device by double clicking on the LON device or using the 'Edit' button at the bottom of the Lon Device Manager view. Enter the correct subnet address and a unique node address for the device. Commission the LON device regardless of whether it has been commissioned before.

Issue  To convert a 0 - 20 mA signal into an acceptable form to be used into a variety of controller types. Environment Sigma BAS Micronet X96 controllers X32 controllers IAC controllers Micronet controllers Cause Some controllers will not accept a 0 - 20 mA signals and therefore the signal must be converted. Resolution To achieve this conversion, please follow the instructions below. Install a 500 ohm 0.1% resistor in series with the 0 - 20mA signal. From across the resistor, take the signal to the controller . The Universal Input or Analogue Input should be set as a standard voltage input.

Issue How to calculate the pressure drop across a fully open valve Environment Valves Cause End user wants to calculate the pressure drop across a  valve for a given flow rate. Resolution 1. Select a valve to suit the application and note its Kvs. note if the figure is Cvs then Cvs * 1.03 = Kvs 2. Flow rate is required. P (bar) = (m3/hr / Kvs) squared. or P (bar) = ( (l/s * 3600 /1000) / Kvs) squared. To convert to Bar to Kpa:  1 Bar = 100 Kpa

Issue "Field Unit Not Configured" error during download Environment Vista System Plug-In Xenta programmable controllers  Xenta 280, 281, 282, 283, 300, 301, 302, 401, 401:B Cause If trying to download the application and parameters in a Xenta controller and the error "Field Unit Not Configured" is received, one cause that has been found is when an Xenta base unit is placed in a LonWorks group (even if it appears to be a part of a Xenta group). Resolution The group in question should be deleted from the Vista database pane in the Vista System Plug-In. Update the Vista database and the controllers imported into the Vista Database should be created in proper groups. Verify that the group is tagged correctly and then update the Vista database once more. Verify for the final time in Vista Workstation that the group is a Xenta group before downloading to the controller in the Vista System Plug-In. You may also drag that Xenta unit into an existing Xenta group after it has been re-imported.

Issue For doors with long wire run to the controller it is very important to follow the recommendations as far as resistor tolerance and wiring distance and gauge is concerned.  If a door still exhibits door switch trouble issues due to length etc. one possible solution is to use a resistance decade box to determine what value resistance should be used instead of the standard 10K ohms Environment AC1 AC1Plus CX9702 ACX5740 ACX5720 ACX701 ACX781 Cause Doors with extra long run to the IOU module / controller may produce trouble condition on the supervised inputs due to wiring issue; in some cases it may be necessary to replace the 10K ohms resistor with a different value to compensate for wiring. Please follow the procedure outline below to determine the correct resistor value to use. Resolution If a door exhibit supervised input trouble issues due to wire length etc. one possible solution is to use a resistance decade box to determine what value resistance should be used instead of the standard 10K ohms, when doing this it is important the find the resistance value in the middle of the range, this will avoid random trouble due to temperature variations etc if the value happens to be right at the edge of the range. To find the correct value use the following procedure: With the door closed start with the resistance decade box at 10K ohms. While monitoring the value of the input modify the resistance (either up or down) until the input reads CLOSED. Write down this resistance value. (VAL1) Continue to modify the resistance in the same direction until the input reads trouble again, write down this value. (VAL2) Pick a resistor value that is in the middle between VAL1 and VAL2 and use this value at the door instead of the standard 10K Ohms NOTE: for series/parallel resistor type it may be necessary to use two decade boxes to find the correct resistance value.

Issue When using SQL 2008 or SQL 2008 R2, I/NET will crash randomly. Referring to the system Event Log, you can see a SQL error happened just before I/NET crashed, called "There is insufficient system memory in resource pool 'internal' to run this query." Product Line EcoStruxure Building Operation,TAC INET Environment I/NET SmartStruxure Cause According to Microsoft Knowledge Base, this problem occurs for all the following reasons: There is a bug in the code that is used to evaluate how many rowsets are required to perform a sorting operation. Therefore, the code greatly overestimates the numbers of rowsets. The required grant estimate in full-text is 64 pages for each rowset that is required to sort. There is a large request that blocks the system from using the memory that is reserved for the full-text query. Resolution Install the newest SP to the SQL 2008 or SQL 2008 R2 being used. Download Microsoft SQL Server 2008 SP3 Express Edition or Microsoft SQL Server 2008 R2 SP2  Express Edition from the Microsoft website. If this doesn't help, please follow Create Error Log for I/NET to turn on the error log for I/NET and then send the log in to your local country product support group for further troubleshooting.

Issue Space temperature sensor calibration using the Xenta 102-AX plug-in Environment Xenta 102-AX Plug-In Cause The space temperature of a 102-AX can be calibrated in three locations:   M/STAT, service menu OP > CSS, resolution 0.1° Vista Workstation, VAV_Controller.UCPTvavSelection.CSS, resolution as entered Xenta 102-AX Plug-in, Browser tab > UCPTvavSelection, resolution 1° The first two allow resolution at least as fine as 0.1° step sizes on the offset.  The LNS plug-in, however, by default only allows whole integer 1° step sizes. Resolution Read to the end before you try this.  NOTE:  It is recommended to make this fix prior to opening the plug-in on a VAV box that has already had the space temperature calibrated via the M/STAT.  Failure to do so may result in the desired calibration being rounded to the nearest whole degree. From the Xenta 102-AX plug-in, select the browser tab (or open the LonMaker browser if you wish). Navigate to and expand the VAV controller object and select "UCPTvavSelection.CSS". Past all of the "CALIBR_NOT_ACTIVE" statements, you'll find a couple of numbers - the second one being 32. Raising or lowering this value will raise or lower the space temp by the same amount. But, until now, if you try to enter 33 or 31 you'll find that only even numbered integers are accepted. What to do? Open c:\Lonworks\types\user\TAC\Xenta100.fmt in notepad. Locate line 172 which should appear as UCPTvavSelection#US: text("%m,%m,%m,%d,%d,%d,%m,%m,%m,%m,%m", Change the second "%d" to "%f" and save the file and restart the Xenta 102-AX plug-in. Now you can change that value in finer increments than is necessary.
