Issue How is Enthalpy calculated in Sigma? Environment Programmable Object Prog Point Enthalpy Cause Customers request for this information. Resolution A Programmable Object calculates Enthalpy using the following formula. I = 1.006 * t + x * (2501 + 1.8 * t) where t is the temperature and   x = 0.62198 * (í * pdm / (p - í * pdm)) and at p = 101.325 kPa => x = 0.62198 * (í * pdm / (101.325 - í * pdm))     where   í is relative humidity and     pdm = p` = 101325 * 10A   where   A = A0 - A1/T - A2*logT - A3*10(-T/A4) + A5*10(A6/T)   where A0 = 20.82648355   A1 = 2948.997118   A2 = 5.02808   A3 = 29811.33781   A4 = 32.923061   A5 = 25.21934913   A6 = 1302.8503   T = absolute temperature = 273.15 + t  

Issue How are the licencing requirements for SQL Server 2008 determined when being used on a Continuum LAN installation with multiple workstations.  Environment SQL Server Continuum Licensing. Cause Determining the licensing requirements for SQL Server can be a very complex undertaking, and not something that we can help you with at Product Support. This is because there are a number of variables that must be factored in to the final determination.  Web servers and Marathon virtual servers add their layer of complexity. Even determining the requirements for a simple multi user LAN system with one database server and ten workstations can be tricky since one has to factor things such as how many processors each machine is running as well as how many machines will be connected to the database.   Resolution The following guide is a starting point. To bid a job however, I would recommend working with Microsoft to determine the requirements. SQL Server 2008 Licensing Guide.pdf

Issue A change is made to a public signal in TAC Vista Workstation, which was created in a Xenta Server XBuilder project, changed back to the initial value after performing a download to this Xenta Server. Environment Xenta Servers (Xenta 511, Xenta 515, Xenta 555, Xenta 527, Xenta 701, Xenta 711, Xenta 721, Xenta 731, Xenta 913) XBuilder Tested with Windows Server 2003, Window XP SP3 Cause If a path name is changed of a signal, for example, change the "the site name" folder name to another name, Vista consider this change as a major change, and Workstation will not be able to find the new path of the signal. Therefore, the signal will return to the initial value which is initialized in the Menta object. Resolution Suggestion is making all the infrastructure change at the beginning if you can. If there is a need to change the path, make sure all the initial values are reflect to the current values in Workstation. Then, make the download to the Xenta Server.

Issue When was the GCS bus controller discontinued? Environment Network 8000 Cause Field request Resolution The GCS controller was discontinued in 2001.

Resolution   Do a full uninstall of Continuum using the following procedure. Uninstall Continuum from Control Panel. Delete  ProgramFiles\Continuum with all files and folders. Delete Andover Controls Folders from the computer registry.  Note: A backup should be made of the registry before making any changes to the registry. Reboot the computer. Logon using a Local Administrator user. From Disable the following services... Virus Protection, Anti-Spyware, FireWall software, Windows Defender, Windows Software Protection Services From User Account Control Settings and set the protection level to Never Notify. Install Continuum.

Issue Some users are unable to see I/NET values on a graphics page displayed in a 527 Environment Xenta 527 TGML Cause User permissions on the 527 must allow the user to access the I/NET links that are being displayed Resolution Log out of the 527 Log in as the root user In the Configuration folder, select User administration Modify the user that was having issues. Click on the ".." link at the top of the folder list till you are in the root folder Click on the "inet" link to modify permissions of the I/NET folder Give the user read and read/write access Save changes

Issue The transmit and receive lights on BCX comm 2 stay lit continuously minutes or hours after the Infinet bus is connected. Environment BCX9640 i2920 Infinet Cause Electrical interference or noise being introduced into the Infinet bus. Resolution Removed the to i2920 controllers from the infinet.  Since these were the only controllers powered by 120 volts it seemed likely that they were a potential source of interference from the power wiring to the Infinet cable. 

Issue How do TAC Vista server trend logs affect the performance of the server and LON network? Environment TAC Vista server LON Network Cause The bandwidth of the LON network is for all communication on the LON wires to share. This includes all graphics, object transfers, etc. Resolution The bottleneck is the communication to the lon network. Depending on what interface (LTA) you are using Vista can handle about 15-40 read/writes per second. Many Vista Server trend logs would increase the amount of information being sent out on the wire and if there is a sufficient number of them, you may see some delays on other forms off communication: i.e., graphics, object transfers, etc.

Issue How many characters can a comment field in TAC Menta have? Environment TAC  Menta Cause How many characters can a comment field in TAC Menta have? If you exceed this length, the application may not work as expected. Resolution There can be 30,000 characters.

Issue Downloading to an SCU and a DPU 7920 Mipped board goes to 33K-38K and then fails. Environment All versions of I/Net software. Cause Possible bad memory location on the controller and or device that does not allow the device to be downloaded all the way. Resolution Change the address of the sublan device Download the bin file and database to it Go to Network Configuration and verify that the doors show up and can be saved Verify that the device functions normally again.

Issue A digital command (by schedule or by manual override) must be linked to a supply fan wired to a Microzone II controller.  How does it get programmed? Environment Niagara R2 ASD driver Microzone II Cause Minimal experience with the Network 8000 product line Resolution Link the output of the native Niagara object to one of the digital inputs of the MZ2EmsDi object. Ensure that the Microzone's "emsControlDefault" is set for "On".  This can be checked on the Properties > Config tab for the Microzone's Shadow object. Using serial tunneling with PSI, ensure the same Microzone's EMS block's output attribute "EMS" indicates "ON".  This means the Microzone is under control from the UNC.  If it is OFF, then the Microzone is in a stand-alone mode of operation. The digital command from the UNC station is now available at the corresponding DV output of the EMS block in the Microzone.  It can then be linked to another block involved with fan control.

Issue Can a DMS-350A controller replace a DMS-35 controller? Environment DMS Cause DMS-35 has failed and customer has a spare DMS-350A from a previous retrofit. Resolution Yes, it is possible. To replace a DMS-35 with a DMS-350A, ensure that at least one DCM is included (the MicroSmart controllers connect to the DCM and the DCM connects to the DMS-350A). Ensure the firmware level in the DMS-350A & DCM is the same (or higher) than the MicroSmart controllers.  For example, if the MicroSmart controllers are revision 10.x, then the DMS-350A & DCM must be revision 10.x or 11.x. The DMS-35 database will not install directly into a DMS-350A because of the DCM.  The points in the MicroSmart controllers will have to be re-linked thereby creating a new database.

Issue Operation of the "Speed Clock" facility. Environment Drayton DC1100 DC1400 DC1100/1400 Speed Clock Cause Information on the enabling/disabling of the "Speed Clock" function. Resolution The "Speed Clock"  function on the DC1100/1400 controller allows the user to test the controllers timed functions in a short period of time. It is enabled / disabled as follows; Rotate the controller rotary switch to "SET". Navigate through the menu structure to "System Menus / Alter Settings / Enter Password, and enter a password of 0402. Choose either to "Enable" or "Disable". Return the rotary switch to "Auto" to run the test.
