Issue SNVT_str_asc (ASCII string) is being brought into/sent out of Menta. SNVT output for "location" required by job specs. What are the capabilities for handling ASCII strings in Menta? Environment Menta 5 SNVT_str_asc Cause Menta does not have a very robust ASCII string handling, but it can be done. Resolution Menta can use special modes on the PIDI block to encode/decode ASCII characters into decimal character values. Macro libraries exist to perform these actions: Right click in the white space in Menta and select "Load Macro..." Navigate to Macro Block Library > Miscellaneous > SNVT Load str_asc_OUT2.AUT for an example of outputting a SNVT_str_asc Load str_asc_IN343.AUT for an example of inputting a SNVT_str_asc Different string handling applications are available: Str_asc_IN3.AUT Str_asc_IN248.AUT Str_asc_INtext.AUT Str_asc_OUT2.AUT Str_asc_to_str_int.AUT Str_int_IN_OUT1.AUT Str_int_IN343.AUT Str_int_OUT2.AUT Str_int_to_str_asc.AUT

Issue An error pops up when editing a point in Video Administrator "The user currently logged on does not have edit rights for this object". Environment Continuum Video Administrator Windows XP Windows Vista Windows 7 Windows Server 2003 Windows Server 2008 Cause There is an issue in earlier versions of Continuum 1.90/191 when using Video administrator that if an object was deleted from the controller and video admin is left open, you will receive the error.  Resolution Upgrade to version 1.92 or greater which corrects this issue Create another point or delete the original and recreate it.

Issue Badge layout (.dgn file) is set for landscape orientation. Print preview looks good. Attempt to print  a badge on a MagiCard Rio 2E. Badge prints with portrait orientation. Environment CyberStation MagiCard Rio Cause Magicard Rio driver properties has a selection for "Application Determines Orientation". If this printer properties setting is selected and the printer properties orientation setting does not match the application orientation setting (Continuum Make/Edit Badge, i.e. EPIDesigner ), the printout may not be what is desired.  Resolution Check the Magicard Rio driver properties setting for "Application Determines Orientation". Make sure, if this printer properties setting is selected, that the printer properties orientation setting matches the application orientation setting in EPIDesigner. 

Issue Running I/O Server as a service and an error 1075: The dependency service does not exist or has been marked for deletion pops up. Environment Running I/Net as a Host Tool under TAC Vista and wanting to configure I/O Server to run as a service. Cause I/O Server requires that MSSQL be tied to the dependencies of the service and when it is not listed, it will generate that error. Resolution When this error comes up, there are several things that needs to be checked to verify that it is set and connecting to the correct database in I/NET: Right Click on My Computer and go to Manage. Select Services and Applications, expand that and select Services. Select I/O Server, Right Click and select Properties then click on Dependencies. MSSQL should be listed in there and more than likely it is not and has to be added. To add it, go to run and type regedit, go to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\INet7IoSrv] DependOnService – add the SQL instance (for example MSSQL$TACVISTA) and the TAC Vista Server (TACOS). This multi string value should list:RPCSS,TACOS, MSSQL$TACVISTA Restart the PC and it I/O Server should be running as a service now.

Issue Change the path of acctrace .csv file Environment Continuum Windows XP Windows Vista Windows 7 Windows Server 2003 Windows Server 2008 Cause There are permission restrictions to the Continuum folder or there is a need to change the path to the acctrace .csv output file. Resolution If permissions are restricted to Continuum, you can change the path to this file. A good troubleshooting step is to send the file to c:\temp When starting acctrace there is a field called "Filename for trace output:" To change the path for the .csv file add the path in the field called "Filename for trace output:" Ex. C:\Temp\ACCTrace_datetime.csv   (leave the actual datetime that the program creates and only add the path C:\Temp ahead of the filename) * On a Windows7 PC, the User Account Control changes the default path where files are created by ACCTrace. If Continuum is installed on the C drive, look in the following path for the trace file that is created: c:\users\username\appdata\local\virtualstore\program files\continuum

Issue In a Niagara G3 station, the BACnet Service indicates "routing enabled = false", even though it had been set = true. What caused the change? Environment Niagara G3 station in an ENC with BACnet / IP enabled Cause The ENC has detected a routing loop and automatically stops routing BACnet / IP messages, and sets the "Routing Enabled" flag = false. Resolution This can be caused by having two or more devices routing to the same network number.  Network numbers must be unique throughout the entire BACnet network.    Locate and remove the cause of the routing loop, which is more than one path to a BACnet device.   Procedure Details: Open platform director Watch output for network number error.   (e.g. Bacnet Network Misconfiguration detected(3): Network number update frequency indicates possible router loop on network 20!!!)  Check BACnet devices with Routing enable and make sure all networks have a unique network ID.

Only alarms that are currently in a Fault or a Offnormal state will be displayed in the Alarm Console window.

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 XBuilder allows for the target type to be changed via the Project menu > Change Target Type. This will change all references in the project if changing from a Xenta 527 to a Xenta 731, for example. Sometimes this menu item is not available and appears grayed out. Environment XBuilder Vista Classic Network Xenta Servers Xenta 511, 527, 701, 711, 721, 731, 913 Cause When a Xenta controller is used as a Xenta Server in a Vista classic network, there are references in XBuilder to the Vista database that will prevent the target type from being altered. Resolution Save a copy of the database XBuilder project to the hard drive.  File > Save As... Open XBuilder in a "stand alone mode" (Start > All Programs > Schneider Electric > TAC Tools 5.1.X > XBuilder) Open the project from the hard drive Select Project > Change Target Type. This option should now be available. Change target to the desired type and send to target. Note: The device in the Vista database has not been updated by this process. If the Xenta Server needs to change types, this must be done in Vista Workstation. Create a new Xenta Server and then use the XBuilder menu Vista Database > Save As... to reassociate the XBuilder project with the database object.

Issue Is part number 40-1758, end of line resistor, still available for purchase through Schneider Electric?   Environment Network 8000, IA Series BACnet Controller Cause Part is no longer available for purchase through Schneider Electric Resolution Part number (40-1758) specified for the 120 ohm EOL (end-of-line) termination resistor is no longer available for purchase through Schneider Electric.  The resistor is utilized for RS-485 communications trunks (e.g. Network 8000, BACnet, etc.).  This resistor is a common part and is readily available for purchase through electronic stores or catalogs.    The specification for the resistor is as follows: Nominal value: 120 ohm Tolerance: +/- 5% or better Power rating: 1/4watt metal film Temperature coefficient: +/- 200 PPM or better Maximum voltage: 250 volts

Issue Logging into Vista Workstation results in error: "Can not connect to TAC Vista Server, No such interface supported" Environment Vista Cause Some connection between the Vista Server and the LNS Server has been broken.

Resolution Uninstall TAC Vista, system plug-in etc. Delete any TAC Shared folder in the \\Program Files\Common Files catalog Reinstall Vista

Issue How many CALs should be purchased for a Continuum system? Environment CyberStation Cause Licensing requirement for MS server Resolution The number of Client Access Licenses (CAL) needed depends on how many CyberStations will be at the site. CALs needed are: 1 for Windows and 1 for SQL. CALS are typically purchased in quantities of five. So, 3 Continuum workstations would require the server to have 5 of each.

Issue Can not see bCX4040 in BACnet view following Find New BACnet Devices from the root. CyberStation and controller are located on the same subnet, no BBMD configuration is required. Environment CyberStation bCX4040 b4920 Cause Subnet mask mismatch between PC and bCX Subnet mask not property configured in controller or the PC Resolution Login to controller's configuration web page and set the subnet mask to the appropriate value for the network. Submit the changes and re-start the controller. If the mismatch is on the PC side, fix it in the network properties in windows control panel.

Issue Windows 7 Standalone v1.93. Logged into Windows as admin. Try to edit Continuum menu page to put in custom backgrounds and  new .mnu file. Get error when going to run mode: "Access to c:\program...\userprofile\continuum.mnu was denied". Environment CyberStation running on Windows 7 Cause Windows 7 has a security feature called User Account Control Settings that is designed to prevent potentially harmful programs from making changes to your computer. The default setting is Level 3 of 4. This setting may prevent the .MNU from updating.     Resolution Note: The windows logged on user must have administrator-level privileges to perform this change. Change the User Account Control Setting to Never Notify. Open Control Panel -> User Accounts. Click on Change User Account Control Settings.   Drag the control to the lowest setting (Never Notify) and save. Restart Windows.

Issue The shadow objects are showing orange "fault" but the values continue to update? Environment G3 (Niagara) ENC, R2 UNC Cause A shadow object will go into fault (orange) condition when the LonWorks service is reading a value that it cannot properly decode.  This "fault" condition is usually related to a SNVT enumeration that is receiving a value out of the standard SNVTs range.  This is typically seen with enumerated SNVT types (e.g. SNVT_occupancy, SNVT_lev_disc, etc.).  For example, an application in the controller is programmed to show occupancy as a value of 0 or 100. The user directly connects the object in the application to the nvoOccupancy tag.  Valid enumeration values for this SNVT are 0, 1, 2, 3, etc.. When the value of 100 is read the shadow object will go into fault (turn orange) because a value of 100 is out of the enumeration range the SNVT_occupancy understands.       Resolution Use WorkPlace Tech to evaluate the controller program and correct any object  to SNVT links that could receive a value outside of its acceptable values.
