Issue When the WorkPlace Commissioning Tool browses a network or internetwork, not all controllers on the network will be found. Environment WorkPlace Commissioning Tool Cause Increase the reply timeout value in WorkPlace Commissioning Tool Resolution If controllers are missing from the list, the recommendation is to Refresh the list after the first attempt  Increase the reply timeout value in the WorkPlace Commissioning Tool to 40,000 milliseconds or greater. With large quantities of controllers (for example 80 or more), wait for the entire reply timeout value to expire for the list to stabilize.

Issue When using Link Builder in the WorkPlace Commissioning Tool, a change to the COV Client Subscription Lifetime to large minute increments (i.e. 60 minutes), is rejected. Environment WorkPlace Commissioning Tool Cause Incrementing the current values in large minute is known to create an issue, implement the below work-around to increase the lifetime value. Resolution The work-around for this issue is to change the COV Client Subscription Lifetime from its current value to the next incremental value (up one minute) and then to the desired value (i.e. 60 minutes).

Issue Miscellaneous fixes in Workplace Tech 5.5 and 1.4 controller firmware. Environment Workplace Tech 5.5 1.4 controller firmware Cause Require detail on what miscellaneous fixes in Workplace Tech 5.5 and 1.4 controller firmware. Resolution Visio 2003 generates an error and crashes when attempting to save a Visio drawing outside of the WPT environment.  In WPT, the existing application tab in the add application to project dialog area is unable to open and add an existing application drawing. The MNB-1000 will reset in response to a read or write request for the profile_name property or background BACnet object. Cannot read/write background BACnet AO, Floating Actuator or PWM object in MNB-1000. AppLED stops updating in the MNB-1000. Sometimes an unsupported property response when reading BI object name in the MNB-1000. Power up delay object did not work correctly in the MNB-1000. Single and sequence loops incorrectly calculate output.  This issue was found when single and sequence loops were set up with large throttling ranges and had a small positive deviation from setpoint. During these conditions, the output of the loop would intermittently go to 100% output and then return to normal operation. This issue applied to MNB-1000, MNB-300 and MNB-Vx controllers. Interstage delay fails after power cycle causing outputs to come on after controller power cycle of MNB-1000.  Dual delay object may be in incorrect state after controller power cycle of MNB-1000.  There was an issue found where the Dual Delay had a 50/50 chance of coming up in the correct state after a power cycle.  Control object RAM not initialized correctly after a download of an application. Floating Actuator object may oscillate at 22.22 and 66.77% output. This issue was reported in MNB-1000, MNB-300 and MNB-Vx. BACnet flow balance values except BoxFlow can sometimes show error.  COV increment property of the VAV Actuator object does not take effect. Using the MN-Sx sensor to change temperature calibration does not work when temp calibration is set to NA from WPT or a BACnet tool and can lock up S-Link communications for MNB-300 and MNB-Vx controllers Overridden and Out_Of_Service flags for PWM and momentary SS objects not previously supported in MNB-300 and MNB-Vx controllers. COV increment property not previously supported for BI count output of MNB-300 and MNB-Vx controllers.

Issue How to get SQL Server 2005 to work with a Niagara G3 Enterprise Network Server. Environment Niagara G3 Enterprise Network Server SQL Server 2005 Cause The SQL Server need to enable TCP/IP and open TCP port number 1433. Resolution "...To get SQL Server 2005 Express (the free edition) configured properly simply follow these steps... Download SQL Server 2005 Express Edition here. Download the SQL Server Management Studio Express from the above URL (note: advanced services are not needed). This is optional but it does provide a useful interface for running SQL queries if desired. Before installing SQL Server 2005 Express Edition, ensure the user is logged on with administrative access to the PC and all older versions of SQL Server are uninstalled. When installing SQL Server 2005, ensure mixed mode is enabled and the give 'sa' user a strong password. Once installed, open the SQL Server Configuration Manager ('Start', 'Programs', 'Microsoft SQL Server 2005', 'Configuration Tools', 'SQL Server Configuration Manager'). Once the Configuration Manager has been opened, enable TCP/IP so G3 can connect to SQL Server (by default this is switched off). Using the tree, navigate to 'SQL Server 2005 Network Configuration' and then 'Protocols for SQLEXPRESS'. Right click TCP/IP and select 'Properties'. The TCP/IP Properties window should now appear. On the first tab labeled 'Protocol', ensure the 'Enabled' property is set to 'Yes'. Go to the second tab labeled 'IP Addresses'. In the section labeled 'IPAll' delete any entry in 'IP Dynamic Ports' and enter the value 1433 in 'TCP Port'. Once completed click ok.  Note that the default port is a 5-digit number that will NOT work.  It must be removed. Restart the SQL Server Express service. If it can't be located easily in Windows, then reboot the computer. Niagara G3 should now be able to connect to SQL Server 2005. Before attempting to connect, ensure all firewalls are properly configured so the connection can be made. If running the Enterprise Network Server on a different computer, then open up a Windows command prompt on the ENS computer and type 'telnet yourIPAddressGoesHere 1433'. If the command prompt window goes blank then connections can be made to this IP address and port number. Open Workbench and run up the desired station. Ensure the station is licensed to use the rdbSqlServer feature. Add the 'RdbmsNetwork' component to the server station. Add the 'SqlServerDatabase' component. Configure the properties for the 'SqlServerDatabase' component. Type in the IP address, port number (1433 in this example), user name and password for the connection. Ping the 'SqlServerDatabase' and ensure its status is 'ok'. Export historical data to the Sql Server database by adding a new 'SqlServerHistoryExport' component and setting up its 'History id' property to point to an existing history already in the station". Ensure Niagara G3 version 3.0.100 and above is used in order for the connection to work.

Issue When using XPSI and serial tunneling on Windows 2003 Server, this error occurs:  "NTVDM encountered a hard error" Environment XPSI Windows 2003 Server Cause Environment settings for TEMP and TMP is not 8.3 namespace compatible. Resolution "Most ntvdm errors can be fixed by modifying the TEMP and TMP environment settings to make them 8.3 namespace compatible. The default path for the TEMP directories is:  %USERPROFILE%\Local Settings\Temp This will (typically) expand to something like: C:\Documents and Settings\Administrator\Local Settings\Temp 16-bit applications cannot  manage the spaces or long file names, and will generate ntvdm errors, even if not explicitly referencing the TEMP directory. Either use a common temp location (i.e C:\Temp) or use the short version of the path.  For the Administrator ID, the short filename path is C:\DOCUME~1\ADMINI~1\LOCALS~1\TEMP Check these names by using ‘dir /x’ The variable settings can then be changed for each user by going into My Computer -> Properties -> Advanced -> Environment Variables -> Set TEMP and TMP to c:\temp or the short filename version Also, consider the PATH environment variable, and any INI files that may be used. The short filename for the "c:\Program Files" directory is "c:\progra~1" Here is how to disable 8.3 naming in the registry. Note - "Edit the registry by using Registry Editor (Regedit.exe or Regedt32.exe). If Registry Editor is used incorrectly, serious problems can occur requiring a reinstallation of the operating system. Use Registry Editor at your own risk." http://support.microsoft.com/kb/121007/en-us

Issue In the process of upgrading a Niagara G3 ENC from version 3.0  to version 3.1, the station fails to start due to an invalid license. Environment Niagara G3 ENC Cause In order to complete an upgrade to version 3.1, it is necessary to obtain a 3.1 license. Resolution Ensure that a new license is available to install in the ENC before upgrading. Once the ENC has been upgraded it cannot be downgraded back to 3.0 unless it is done by the factory.  If a new 3.1 license has not been installed, the ENC will be inoperable until it is installed.

Issue When using COV with BACnet and Niagara R2, what object types should be used with it? Environment BACnet Niagara R2 COV Cause To get the most benefit from implementing COV and make certain it performs well. Resolution Per the Niagara R2 BACnet Integration Manual follow these COV Strategies: Best Candidates for COV:  In general, the best usage of COV is for objects that have values that change infrequently - typically binary and multistate input objects or binary and multistate value objects. These are represented by BACnet shadow object types BI, BV, MSI, and MSV. You can also use COV for analog input and value objects (AI and AV). However, to reduce notifications you would have to increase each object’s covIncrement value, which would also reduce sensitivity to changes - consider that only changes larger than the covIncrement value will be reported. Poor Candidates for COV:  Starting in release r2.3.4, the priorityArray property of output-type objects (AO, BO, MSO) and value-priority objects (AVP, BVP, MSVP) is polled, in addition to presentValue and statusFlags properties. This is done as part of a “rewrite mechanism” (see “Rewrite Mechanism,” page 3-25). Although you can configure any of these BACnet objects to useCOV, the object remains in the poll queue to receive priorityArray - as this property cannot be received using SubscribeCOV logic. Therefore, configuring these objects to useCOV will not significantly reduce message traffic. The poll message for each will request only one value instead of three, but this typically makes little difference. Therefore, it is recommended that you do not configure any output-type and value-priority objects for COV usage, unless the device can support plenty of COV subscriptions, and you have already subscribed all of the input and “non-priority” value type objects.

Issue What parameters are used to regulate the speed of the LON trunk in a Niagara R2 integration? Environment Niagara R2 Cause Configuration of LON devices create unnecessary network traffic from changing values. Resolution There are two settings that can regulate LON traffic: 1. In the LocalLonDevice properties, the maxSendTime parameter specifies the maximum amount of time the local lon device (which is the UNC station) waits to send out a value that has not changed. 2. Also in the LocalLonDevice Properties, the minSendTime parameter specifies the minimum amount of time that must elapse between network variable updates for values that are changing rapidly. Consult the Niagara LonWorks Integration Guide for more information.

Issue While trying to connect to a BACnet/Ethernet network with Workplace Commissioning Tool, the following error appears:   "An error occurred while open communications. Please verify communications settings and try again." Environment Workplace Commissioning Tool BACnet/Ethernet network Cause Workplace Tech and WorkPlace Commissioning Tool use the NDIS BACnet Ethernet Packet driver to connect to BACnet/Ethernet networks. This driver's file name is KPF.sys and is known as a Kernel driver. If this file is not installed correctly or is halted by another program, BACnet/Ethernet will not function. Resolution To identify if Kernel driver is the issue, follow the steps below:   Open system information from Windows - Accessories - System Tools - System Information Navigate to Software Environment - System Driver Look for KPF in the name column. If it is not there, re-install WorkPlace Tech as an administrator.   Make sure there is no software running that might not allow this file to be loaded.  Some virus software may also block the installation. If this file is there, check the state column to verify that it says running. Note:  this driver will only say running if BACnet/Ethernet is being used. If the file is there but it is not running, ensure that the actual location of the file in Windows Explorer is the same as the file column location in System Info. If they are not, then copy the file to the location listed in System Info. To verify that this driver is working correctly, use the net start command at a command prompt (type "net start kpf"). If the driver is working, it will indicate that it is already running. As this is a Kernel level driver, if the above steps do not resolve the  issue, un-install WorkPlace Tech and re-install ensuring a local administrator account is used.

Issue The Niagara G3 platform daemon will not run using an administrator account in Windows. Product Line TAC IA Series Environment Niagara G3 Cause Possible causes: The niagara service is not started IIS is running on the computer Port 3011 is blocked Authentication Resolution There are a number of possible causes: The niagara service is not started. Run Platform Daemon (Start > Programs > Vykon AX Supervisor > Install Platform Daemon) IIS is running on the computer.  Disable IIS in Control Panel > Administrative Tools > Services Port 3011 is blocked. Ensure there are no firewall, antivirus, or remote access software blocking port 3011 There are two types of platform authentication: Basic platform authentication (the default for a Windows-based host) provides integration with existing Windows installations, and provides two levels of platform access, which are determined by a user’s group membership(s). The levels of platform access are: User - Platform access at this level allows full use of most Workbench platform views. This includes the ability to install or delete licenses and stations (including the one running), also to install, reinstall, or upgrade the platform dist file and/or modules, and to start, re-start, or stop a station. Admin - Full access. This includes all user-level platform operations, plus the ability to configure host TCP/IP settings and dial-up configuration, change platform authentication, change platform daemon HTTP port, change host date/time settings, use the File Transfer Client, and reboot the host. Digest platform authentication provides only full level platform login access, using a single platform user account. With Digest platform authentication, there is no linkage between Windows OS user accounts and the platform administrator. If Basic authentication does not work, then Digest authentication must be used. To enable digest authentication, do the following: Using Notepad or WordPad, open the daemon.properties file located in C:\niagara\[release]\daemon folder Add the following lines to the end of the file: installFlag=doc authtype=digest/file user=[username] (where you select the username) password=[password] (where you select the password) stationIsAdmin=true Save, then close the file Restart the platform daemon (Start > Programs > Vykon AX Supervisor > Install Platform Daemon) Launch Workbench AX, then open the platform using the username and password you provided in step 2. Consult the Niagara AX Platform Guide for more information.

Issue Why does the Niagara G3 platform running on a computer have no Station Copier or Distribution File Installer feature? Environment Niagara G3 Cause In release 3.0 and earlier of Niagara G3, various issues arose with these features. Resolution Beginning in release 3.1, the features have been excluded on the local host. However, these features ARE included in the platform on the ENC controllers.

Issue What properties are updated in a MNB Controller COV Client objects? Environment MNB Controller Cause Information about the properties sent to the COV client when a value of the point changes. Resolution COV Client objects can only update Present Value & Status properties.

Issue In Niagara R2 Workplace Pro, a Save Runtime DB command on a UNC does not work.  This error message appears: "DB ADMIN COMMAND ERROR EXCEPTION; CONNECTION REFUSED". Environment Niagara R2 Workplace Pro UNC Cause The UNC has its http port configured for a port number other than the default port of 80. A line must be added to the station.properties file to specify the new port number. Resolution Open the admin tool and log into the UNC (not the station database). Right-click on the station name that indicates "running" and select Edit > Properties. The station.properties window will open (typically indicates autoStart=true and autoRestart=true). Add a line to this file that specifies the new port number.  For example, if the station database was configured to use port 8080, the line would read:  httpPort=8080 Choose File - Close and Save when prompted. NOTE: To enable this change, the UNC must be rebooted.

Issue How to migrate a SIGNAL for Windows 95/98 (version 4.4.1 or earlier) database to a new SIGNAL for Windows XP (version 5.0) installation. Environment SIGNAL for Windows 95/98 version 4.4.1 or earlier SIGNAL for Windows XP version 5.0 Cause Data on the existing database is crucial and don't want to lose any data during the transfer process from SIGNAL for Windows 95/98 to SIGNAL Windows XP. Resolution Perform a backup of the SIGNAL for Windows 95/98 system. When prompted, select to backup only DATA and BITMAP files. DO NOT SELECT executable files. The executable files are specific to the SIGNAL version for Windows 95/98. If this backup is restored to a SIGNAL for Windows XP computer, the executable files will not work on that operating system. If the only backup available contains the executable files, then restore the backup to the SIGNAL for Windows XP computer. Now, perform a new backup containing only the data and bitmap files. Once completed, delete the SIGNAL folder and the signal.ini and bit.ini files from the x:\WINDOWS directory. Re-install SIGNAL for Windows XP from the installation diskettes. Then, restore the backup containing only DATA and BITMAP files.

Issue When starting SIGNAL for Windows XP, an error message appears stating "Can't run 16 bit Windows program, insufficient memory". This occurs when the SIGNAL program "Startup Type" is set for Automatic. Environment SIGNAL for Windows XP Cause Multiple versions of SIGNAL for Windows XP are trying to run simultaneously. The “active” user profile, as well as, the “All Users” profile are both trying to start SIGNAL. Resolution When it is required to have SIGNAL startup automatically for ALL users, either make the entry for each user profile or only make the entry in the “All Users” profile.

Issue SIGNAL (any version) is installed on new computer hardware that has higher video resolutions. Now, the Monitor program's graphics are not aligned. Environment SIGNAL (all version) PC with high resolution graphic card Cause The new PC screen resolution is not set at the recommended resolution. Resolution All versions of SIGNAL support two video resolutions: 640 x 480, and 800 x 600. Shutdown SIGNAL and use Windows to modify the computer's video resolution to one of these two settings.

Issue On a MNL-800 controller, are resistors required on the universal inputs when wired for pulse counting? Environment MNL-800 controller Cause Knowing the resistor requirement helps implementing pulse count using universal inputs. Resolution UI1 does not require an external resistor. If using UI2 through UI8 as a pulse input, an external 10K resistor to +5.1 V is required.

Issue Why does it take three minutes to create a link in Niagara R2 WorkPlace Pro from an Enterprise Server station to a UNC station? Environment Niagara R2 WorkPlace Pro Enterprise Server UNC station Cause Enterprise Server station attempts to connect to all devices in the address book. There will be latency if there are offline or no longer exist UNC devices in the address book. Resolution When engineering a job it is common practice to load the Enterprise Server station into an engineering laptop and create links to UNCs one at a time. This is not a problem as long as the address book entries are removed from the Enterprise Server station that are not online. Upon creating a link, the Enterprise Server station attempts to connect to all devices listed in its address book. This creates a large latency in completing a link if there are multiple devices in the address book that are not able to respond. To create links in this fashion remove all address book entries from the Enterprise server station's address book that are not online.

Issue When upgrading the MNB-1000 firmware from v1.32 to v1.4, the value of property APDU Retries changes to 0. This will cause problems with any MNB-1000 that make BACnet requests. Environment MNB-1000 v1.32 Cause Firmware v1.4 change APDU Retries to 0, which the value needs to be to 2 or 3. Resolution Set the value of APDU Retries to 2 or 3 using WorkPlace Commissioning Tool or any other tool capable of changing that property. To change the APDU retries follow these steps: Open WorkPlace Commissioning Tool Discover MNB-1000 and select its properties Select the Advance Tab Change the APDU retries to 3 Select OK then restart the MNB-1000 Note: If there problems with COV, make sure this property is set to a value of 2 or 3.

Issue How can an override of a nciMinFlow SNVT be done directly from a container in Niagara R2 WorkPlace Pro? Environment Niagara R2 WorkPlace Pro nciMinFlow SNVT Cause A direct override of a nci is not possible. Resolution However, a change to a nci can be done by doing the following in WorkPlace Pro: Copy and paste the DynamicCmd object from the Local Library\tridiumx\lonworks\conversion folder into the Workspace Link the nciMinFlow property on the VAV shadow object to the Link property on the DynamicCmd object In the Config tab of the DynamicCmd properties, configure the floatConversion properties as follows: 1st dropdown: Volumetric Flow, 2nd dropdown: liters_per_second, 3rd dropdown: cubic_feet_per_minute In the Visual tab, type "MinFlow" in the float box Apply the changes In Monitor mode, right-click on the DynamicCmd object, and select MinFlow Enter the desired value in CFM.  The nciMinFlow SNVT in the VAV controller will update the value
