Issue It is not clear which part of the license system handles the end-user license and which part handles the demo license. Having both TAC Vista and EcoStruxure Building Operation(EBO) installed on the same PC can cause conflicts in the license system. Product Line EcoStruxure Building Operation   Environment Building Operation Enterprise Server   Cause If an EcoStruxure installation is only used for engineering and therefore will only have demo licenses activated, you don't need to install the license server. The service "FLEXnet Licensing Service" is installed by any EcoStruxure software package, and that is the service that will handle the activation of demo licenses. Resolution If you will only use demo licenses on a PC and/or also have TAC Vista installed on the same PC, only install the license administrator and not the license server.   It is also possible to run TAC Vista and EBO using the same License server, please see Lesson Learned SmartStruxure license and TAC Vista license on the same PC

Issue Multical 602 - No pulse output detected for cooling energy from top module 602-0C Environment Kamstrup Multical 602 heating/cooling meter with 602-0C top module (part number MAPULSETOP-C) Cause The 602-0C top module was purchased separately from the Multical 602 meter. The 602-0C top module is factory configured for a heat meter. Output C (terminals 16 and 17) is associated with heat energy CE+ which is stored in the calculator at register E1. The cooling energy CE- is stored in a separate memory location of the calculator at register E3.  Resolution Configure output C to cooling energy E3 using the METERTOOL HCW software and USB optical eye tool. Contact Product Support for the METERTOOL HCW software and the USB drivers for the USB optical eye tool The USB optical eye part number is MAOPTICUSB Procedure to configure output C to cooling energy: 1. Run the METERTOOL HCW software  2. Place the optical eye over the small window on the front of the calculator 3. Make sure that the optical tool is held in place magnetically and is resting on the lower pins 4. Press the connect button in METERTOOL HCW 5. Select Modules from the menu on the left-hand side 6. Select Configure Top Module from the next screen 7. The configure button will be inactive and in order to make any changes, you must read current configuration. Press the Read button 8. Output C is set to CE+ and that Output D is set to CV+ and the Configure button is now active 9.

Issue Error Message pop up reading: Station Conflict - [Link: 95] Station 00 at site 61 - Xenta527 conflicts with site 63 - xenta737-97. Station Conflict - [Link: 1000] Station 00 at site 03 - Host 3 conflicts with site 90 - Host 9. Product Line TAC INET Environment I/NET Cause Station conflicts occur when multiple devices share the same address. This is always the cause, but Identifying the possible addresses can be confusing. Host Address - The I/NET Configuration unique identifier for each host workstation.  1-250 Link address - The system segment in question. Contains multiple Stations and in DLA multiple sites. 0-99 It is generally advised that you do not use Link 0. The Link will typically define an NPR or Xenta 527. Such as the Link 4 Xenta 527 functions as the bridge between TCP/IP and the Link 4 Controller LAN segment. Site Address - Only used in DLA architecture.(1-63) 0 is only used in non-DLA NPR devices. The site allows for multiple Controller LAN segments to use the same Link address. This changes the description of a Xenta 527-NPR from Link 6, to Link 6 Site 1 and allows Link 6 Site 2, Site 3 and so on. In DLA architecture, the NPR devices will typically all use the same Station Address.  If link 6 Site 1 uses Station 0, Link 6 Site 2 may also use Station 0. Station Address - This is the unique identifier for addresses on a physical controller LAN wire.  You may use 0-63, but one must be reserved for the NPR device. Station level controllers are typically referred to in messaging by a 4 digit address.  Link 4 station 12 may be shorted to 0412.  All controllers in an I/NET system must have a unique for digit label of LLSS. The only exception to this is the NPR device as it function as a gateway and can have a site address to make it unique.  Controller LAN level controller do not show a site label. Resolution Change the address on one of the offending controllers In DLA situations, you can only duplicate the Station address used by the Xenta 527 If a 913 is used on the Controller LAN, it must also have a unique station ID Ensure all Host workstations have unique host ID's Ensure all devices in a DLA architecture have unique Link/Station combinations.  There cannot be 2 Link 4 Station 3s, even if they both have a unique site number.

Issue DC1100/1400, how does the "Set Back" operation work? Environment DC1100 DC1400 Drayton Set Back Cause The Set Back operation has been enabled, but does not appear to work. Resolution There are two modes of operation when using the Set Back function. 1 - Set Back Enabled - Space Night Setpoint - Disabled. - Do not use this option. Expected result At the end of occupancy, the plant will continue to operate, and the compensated setpoint temperature will reduce by the "Flow Night Setpoint" value. The display will show "Set Back". Actual result Controller switches off and displays "Outside Occupation". 2 - Set Back Enabled - Space Night Setpoint - Enabled. Space temperature above "Space Night Setpoint" setting. Controller acts as expected, it switches off and displays "Outside Occupation". Space temperature below "Space Night Setpoint" setting. The plant will switch on, and the compensated setpoint temperature will reduce by the "Flow Night Setpoint" value. The display shows "Set Back". The image below shows the appropriate section of the programming menu structure.

Issue What does the "| n" mean when viewing the properties of an OPC variable in Vista workstation? Problems have been encountered with OPC variables Error messages such as "The object is no longer available in the servers address space", Also, canonical data type or OPC data types. Environment Vista 5.1.X TAC Vista OPC client Cause The "|n" is a reference to the data type or canonical data type as it's called in the OPC standard. In the world of OPC, the client application can be created in on one of many diverse programming languages. To resolve potential issues all OPC data types are assigned a specific Canonical Data Type. When a client application adds an OPC Item to an OPC Group it can use the default data type for the item or it can request the item with a specific canonical data type. If the OPC tool is used then the canonical is added automatically by checking with the server. It's only if variables are added manually that this information is required. Resolution The method used for addressing OPC variables is Folder.Variable_Name|Data_Type  The table below details the data types:  Data Type Canonical Type Size Data Range Boolean 11 1 Bit True or False Byte 17 1 Byte 0-255 Byte Array∗ 8209 1 Byte times Array Size 0-255 Short 2 2 bytes -32768 – 32767 Short Array∗ 8194 2 bytes times Array Size -32768 – 32767 BCD 18+ 2 bytes 0 - 9999 BCD Array∗ 8210 2 bytes times Array Size 0 - 9999 Word 18 2 bytes 0 – 65535 Word Array∗ 8210 2 bytes times Array Size 0 – 65535 Long 3 4 bytes -2,147,483,648 to 2,147,483,647 Long Array∗ 8195 4 bytes times Array Size -2,147,483,648 to 2,147,483,647 LBCD 19+ 4 bytes 0 - 99999999 LBCD Array∗ 8211 4 bytes times Array Size 0 - 99999999 Dword 19 4 bytes 0 – 4,294,967,295 Dword Array∗ 8211 4 bytes times Array Size 0 – 4,294,967,295 Float 4 4 bytes -(3.40 E38 – 1.40 E-45) to (1.40 E-45 – 3.40 E38) Float Array∗ 8196 4 bytes times Array Size -(3.40 E38 – 1.40 E-45) to (1.40 E-45 – 3.40 E38) Double 5 8 bytes -(1.798 E308 – 4.941 E-324) to 4.941 E-324 – 1.798 E308) Double Array∗ 8197 8 bytes times Array Size -(1.798 E308 – 4.941 E-324) to 4.941 E-324 – 1.798 E308) Char 16 1 Byte All Characters supported in the standard ASCII table String 8 1 – n Bytes All Characters supported in the standard ASCII table

Issue Is it possible when starting Internet Explorer: To log on automatically. To start in Full Screen mode. To show a TGML graphic (without system tree) and without entering a user name and password by a shortcut. Is it possible to hide the 2 toolbars as described below? Product Line EcoStruxure Building Operation Environment Building Operation WebStation Kiosk Mode Cause For some applications such as Kiosk screens, these features are needed Resolution Automatic logon This can be accomplished either by using the "Remember me" checkbox on the logon screen, or by using the guest logon feature. To make WebStation bypass the logon screen, create a user with a username of GUEST and a password of GUEST, give this user limited permissions. For 1.7 and later, the password for the GUEST account when used for WebStation automatic logon, is not compatible with the default password policies. Automatic logon will only happen if the GUEST account password is exactly "GUEST". If policies are not changed the automatic logon will stop working after 90 days. Full Screen mode To make Internet Explorer go directly to full screen mode, you can use the "kiosk mode" switch. Create a shortcut with the command  iexplore.exe -k [insert your URL here] Display TGML Graphic without toolbars Open the graphic you require, using the "Open in a new window" right-click command. Copy the URL and create a shortcut with it. When you open this URL the user is taken directly to the graphic, without toolbars or menus.

Issue Visio 2010 crashes whether or not LonMaker is running and both LonMaker and Visio 2010 crash together often when LonMaker is running. Echelon LonMaker An unexpected error occurred. Please save your drawing and exit Visio/LonMaker. Environment LonMaker Turbo Edition Visio 2010, possibly Visio 2007 Cause The "Send to Bluetooth" Add-In in Visio 2010 has been known to cause Visio to crash thus bringing LonMaker down with it. This often occurs when Bluetooth is disabled on the computer. When Visio is not able to access the bluetooth, the program crashes. Another possible cause is that the Add-In is not compatible with DEP. Resolution Steps to remove the Bluetooth add-in The simplest resolution to this problem is to disable the Send to Bluetooth add-in in Visio by following these steps: In Visio 2010 click File and select Options near the bottom of the left-hand pane. Select Add-Ins from left-hand pane then find and highlight the Send to Bluetooth add-in. In the Manage drop down box select COM Add-ins and click Go. Uncheck Send to Bluetooth and click OK. Shut down Visio and start LonMaker.     Steps to disable DEP in Visio In Visio 2010 click File and select Options near the bottom of the left-hand pane. Select "Trust Center" and click "Trust Center Settings" Click "DEP Settings" and remove the tick mark in "Enable Data Execution Prevention Mode" Shut down Visio and start LonMaker.

Issue It may be desirable to the building management to remove web users and operators' privileges to change their own password. Environment Xenta Server Cause By default all users are able to change their own passwords. Resolution While the privilege that each user has to be able to change their password cannot be removed through standard configuration methods, it can, nevertheless, be removed through the FTP server of the Xenta controller. However, these changes will apply to all web users or to all operators rather than just specific users. Connect to the FTP of the Xenta 5/7/9xx controller by typing FTP://x.x.x.x (where x.x.x.x is the IP address of the controller) in the Windows Explorer address bar. Login with the root username and root password. Browse to the ftp://x.x.x.x/www/config/ folder and copy the either the file named operatormenu.xml or webusermenu.xml (depending on which type of user needs to be edited) and copy it to the desktop of the local machine. Open the ftp.cfg file with notepad on the local machine. If you are editing the web user file then delete the following lines: <MENU name="User Administration" value="/wm/useradmin" type="CFGDIR"> <MENU name="Change Password" value="/wm/useradmin/change_password" type="CFGPAGE"/> </MENU> If you are editing the operator file then only delete the following lines: <MENU name="Change Password" value="/wm/useradmin/change_password" type="CFGPAGE"/> </MENU> Save the file to the desktop without changing the name. In the FTP rename the original file by adding a "1" to the end of the name. For example webusermenu.xml would now be named webusermenu1.xml. This way you can keep the original file in the FTP if you ever need to revert back to it. Copy the newly edited file from the desktop to the FTP folder. If you are already logged into the Xenta server then log out and log back in. The menu should no longer be available. Important Note: If the system program is reloaded in the Xenta Server, these changes will be over-written and will need to be re-done.

Issue The Remote Alarm Manager sends a message to the recipient indicating that an alarm has been inactivated. The screen shot below shows how a typical message will appear on the receiving mobile phone. Product Line Other, Satchwell MicroNet, Satchwell Sigma, TAC Vista Environment Remote Alarm Manager version 1.2 Cause An alarm message is generated, and the Remote Alarm Manager processes it in the normal way. After three days and at midnight, the Remote Alarm Manager will send a inactivation message to the on-call recipient, indicating that this alarm has been inactivated. Resolution This is not a fault with the system, it is operating as designed. When a new alarm is received by the Remote Alarm Manager, it is acted on in the way the configuration dictates. If the alarm remains on the system, without being retransmitted, then after three days the inactivation takes place. The 3 days is the default setting and can be changed if required.

Issue Confusion over behavior of the Xenta 121 when using a occupancy sensor. Environment Xenta 121-FC Xenta 121-HP Cause When an occupancy sensor is not defined in the configuration of a Xenta 121 controller the effective occupancy will follow the command given by nviOccManCmd. However, when an occupancy sensor is defined, either as a network bound point or a hardwired sensor, the effective occupancy of a Xenta 121 will behave differently. Resolution The Xenta 121 operates as follows when using an occupancy sensor: The most notable difference in how the Xenta operates are: When nviOccManCmd is in either the OC_UNOCCUPIED or the OC_STANDBY modes then the Xenta 121 will ignore the state of the occupancy sensor. When nviOccManCmd is in the OC_OCCUPIED mode the Xenta 121 will follow the state of the occupancy sensor. Note that this means that the controller could actually enter the unoccupied mode even though nviOccManCmd is set to be occupied. When nviOccManCmd is in the Oc_Nul mode the effective occupancy of the Xenta 121 will Oc_Standby until a signal is received from the occupancy sensor at which time it will change to be Oc_Occupied. This behavior should be taken into consideration when deciding on how to implement an occupancy sensor. It may be desirable to set the nviOccManCmd to Oc_Nul whenever the occupancy sensor should be considered and to set it to Oc_Unoccupied when the occupancy sensor should be ignored. This effectively utilizes the occupied, unoccupied and standby modes as three distinct modes of operation to maximize comfort and efficiency.
