Issue Project specifications call for there to be no default administrator password in the BMS.  Can the ACC user in Andover Continuum be deleted? Product Line Andover Continuum Environment Administrator password Continuum CyberStation Permissions Cause By default Andover Continuum always creates the ACC administrative user on all system but this is deemed unacceptable by some project specifications. Resolution The Andover Continuum default ACC admin user cannot be deleted, however it can be renamed and its permissions can be removed/amended.  

Issue Removing software from a PC may leave behind unused / old registry entries and folders from the removed software, this in some cases may prevent software re-installation Product Line Andover Continuum,EcoStruxure Building Operation,Satchwell BAS & Sigma,Satchwell MicroNet,TAC INET,TAC Vista Environment All supported Operating Systems Cause This is due to the windows uninstall program not fully removing all elements for the software. Some of this is due to windows thinking the the software may have been removed unintentionally and therefor all the previous settings will still be saved in case of  re-installation. For example, when SQL is uninstalled the program folders that contain the database will remain intact. This may be an issue if, for example, the software is removed due to a problem with the original installation. This is when a complete removal off all components and registry entries may be needed. Resolution The best solution for removing all the unused registry entries is to use a program designed to remove obsolete registry entries and temporary files. Some examples of these are: CCleaner, which will allow you to clean up your PC by removing past installation components. Revo Uninstaller  which is useful for removing redundant folders / files / Registry entries.   It may be useful to use both of these programs to ensure a complete cleanup. Revo Uninstaller can be used to remove unused software and then CCleaner to get rid of all the Temp files etc.  Finally remove the relevant folders from within the windows explorer, Example: C:\Program Files (x86)\Continuum Once done you should then be able to install a fresh clean copy of the application software. This solution is current in all versions of Windows including windows 10  

Issue Need information on programming holidays and special dates Product Line EcoStruxure Access Expert Environment Access Expert Hosted software V3 Resolution Programming Holidays and Special Dates   Overview   Holidays are exceptions to a normally scheduled interval. Feenics has made several fundamental changes to the holidays within the Keep by Feenics System. This article will walk through how the new holiday sets work and how to implement them. The holidays apply globally to all schedules.   Updating    The launch of the new holiday system requires a system upgrade within your instance. This upgrade only needs to occur once and is irreversible. To upgrade, click the "Update Holidays" button.   Note: Before you begin converting holidays, there can be no more than 8 holiday sets in the older system for the update to work.   Once that button is clicked, a warning will pop up letting you know that the process is irreversible. Click OK and your instance will be updated.     ***Note: Customers within an Enterprise instance will need to apply this update to ALL shared instances and the Enterprise instance separately.   Adding Holidays   Holidays are added to the system through the "Add Holiday Duration" button. This will add a holiday interval to the system. Holiday Durations   Holiday Durations are days in the system on which, the schedules should not activate. To add a Holiday, click "Add Holiday Duration", then name the day. This day will prevent all schedules from activating unless added to the "Always Active On" column in a schedule. Holiday durations are limited to 255 per instance.  Display Name: The name of the holiday interval, i.e. Valentine's Day, Halloween, Veterans Day. Start Date: The date the holiday interval begins on. End Date: The date the holiday interval ends on. (If the start and end date match, the holiday will be for that day only). Special Date: This flag inverts the behaviour. If this holiday interval is assigned to a schedule interval (via Holiday Groups), the schedule interval will activate for that day. Holiday Group: This selection allows the user to group holiday intervals into sets.  Tags: As in the rest of keep, tags allow for organization and permissions to be set by these groupings.   Holiday Groups   Holidays can be grouped together by using holiday groups. These groups are edited by selecting the "Edit Holiday Groups" button and modifying the Group Name. Holiday intervals are then added to the group by assigning them in the Holiday Group column of the holiday interval. ***Note: The shared holidays between groups should be in their own group. This will allow the non-shared holidays to be applied to schedules correctly.   Applying Holidays   Holidays apply globally to all schedules. A holiday Group can be added to a schedule interval to tell that interval to ignore that holiday.   ***Note: If a holiday exception is added to a schedule interval, the schedule will activate on the day of the holiday, regardless of the day selection on the schedule interval. Special Dates   Special Dates can be used to activate a schedule interval for a day or group of days regardless of the other intervals within the schedule. To add a special date, open the Holidays page and add the day(s) as a holiday interval, then check the "Special Date" box. Add the special date(s) to a group on its own.

Issue Details on Access Expert Keep Alert Feature Message usage Product Line EcoStruxure Access Expert Environment Access Expert Hosted software V3 Cause Details on Access Expert Keep Alert Feature Message usage Resolution The Keep Alert feature in Access Expert comes with a default 500 SMS messages a month. This can be used to send a broadcast to the users on the system. For example, if the administrator wants to send a text out to 50 people based on an event, then that would leave a total of 450 remaining.   Another use case would be if there was an active shooter at a school campus where there are 500 students, then this would be done one time and the max texts would be sent.   Additional amounts can be purchased in 500 amounts based on what the need is for the customer. so that their monthly usage stays within the amount purchased.

Issue WebClient login screen has the webClient background, but no login fields   Product Line Andover Continuum Environment webClient Cause This typically happens when webclient has been installed prior to IIS, so .Net framework does not get registered with IIS. Resolution The resolution is to run the regiis.exe command as follows: From a DOS Command Prompt (as an admin) For Windows 2000 Professional it is: "c:\WinNT\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i" "c:\WinNT\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i" For Windows XP Professional, Windows Server 2003 it is: "c:\windows\Microsoft.NET\Framework\v1.1.4322\aspnet_regiis.exe -i" "c:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i"   For Webclient 1.94 and above, .Net Framework 4 is used "c:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i" Once this command is run the normal login prompt will be presented.

Issue Can a listview showing access events be filtered to only show access events for a specific door? Product Line Andover Continuum Environment Cyberstation WebClient Cause Need to monitor access events for one specific door using a listview. Resolution Create an Access Event Listview (1), add filter if required (2) and set path (3)  Add columns and include a column for DoorId Note the full path that shows up for the door under DoorId after running the listview Edit the listview and add a filter The syntax of the filter string should be:                          (DoorId is like DoorId Path String id)   Note: The filter string will not work unless  "id" is placed at the end of the qualifier.  Also the DoorId Path string must be exactly as it appears under the DoorId column for a door event of an unfiltered event listview.

Issue Troubleshooting I/NET installations and upgrades on multiple client workstations. Product Line TAC I/NET Environment I/NET Seven Multi-workstation Site Cause Options to investigate when unable to install I/NET Software on some PCs Resolution Difficulty loading I/NET Software onto a PC where the site has several PCs, and the software will load on one and not the other hardware. The steps below are intended to be used as a checklist and Compare the differences between working and non-working PCs: Is the memory the same? Is the OS the same or different? Is the OS Configured the same? Does it meet the minimum requirement for I/Net and its applications? TCON298 What are the permissions for the Logged in User? Does the user have full Admin-Rights to perform the applicable installation? Is I/Net being installed for the first time, or is it an upgrade? At what point during the installation does it fail on one versus the other? Are any error logs being generated during the process? Can any other software be installed? Are there any previously loaded applications using a SQL/MSDE DataBase? Has the IP/network/domain status changed? Going through the above steps will help rule out some possibilities.

Issue Xenta 527 Appears offline: Troubleshooting steps. Product Line TAC INET Environment I/NET Xenta 527 Xenta 527-NPR Cause Possible Causes: Ethernet Communication is down Ethernet Port is closed Device is configured incorrectly Device failure Resolution Ethernet Communication is down Using the command prompt, ping the device's IP and trace its route. "ping (Insert IP Address)" and "tracert (Inset IP Address)" Watch to see if the Domain server prints out the correct Hostname.  If the device is shown as offline, there may be an error with Firewall settings or Ethernet communication at the Host Workstation. Connect to the router via Internet Explorer If neither of these is possible, Communication is definitely down on the Workstation side. Next, check the Xenta Server side. Disconnect the Ethernet cable from the Device and plug it into a laptop. See if you are on the network.  Ethernet Port Is closed. If the above process shows that Ethernet communication between the Workstation and Router is valid, you may have the port closed. Use a crossover cable to connect a laptop to the device and see if you can connect to a controller ON THAT LINK in I/NET. Look for live values in Controller Summary.  If you can do this, and you can show that Ethernet communication between the two devices is working, then you most likely have a firewall on port 50069 Contact the building IT department Device is configured incorrectly If, in the above process, you cannot connect to I/NET while directly connected to the Router via an Ethernet crossover cable, the device may be configured incorrectly. Open the active I/NET configuration Profile. Ensure that TCP/IP is enabled Add the Router’s IP address to the Reference Host Table Restart the I/O server Check communication Connect to the 527 via HyperTerminal type setip and verify you have been using the correct IP address and hostname type inethost and add the Workstation’s IP address to the Reference host table. restart the 527 Communication should be restored. Device failure Observe the "Run" light on the device.  It should be solid green. Observe the TCP/IP port LED. If you are actively communicating, this should be blinking. If you are unable to connect to the device via a HyperTerminal Direct Connection or Internet explorer while directly connected, you may have a device failure Cycle Power on the device Connect via HyperTerminal (if you cannot do this, try using the failsafe mode. If that fails, replace the device) Type the command “format” to format the device type “setip” and enter the IP information Download and install the latest system file for the 527 you are using. Remember that the 527 and the 527-NPR use different install files. Configure the I/NET communication in HyperTerminal Other Troubleshooting Steps See if the communication error shows up on multiple computers and, if possible multiple locations. There may be an error with Firewall settings or Ethernet communication that only affects part of a large system Host Workstation. Use a different Ethernet port to connect the 527 or workstation to Direct connect to a controller on the controller LAN via TAP and see if any stations are offline.  It is theoretically possible that some form of electrical failure on the controller LAN has caused the 527 to appear offline.  If you cannot see the entire controller LAN from anyone on one device, you should troubleshoot Controller LAN communication. If this is a recurring issue for the site, please download and use the attached 527 offline response document for information gathering and troubleshooting.

Issue Error in Xenta 527 HyperTerminal     This error happens over and over (with different file sizes each time), and the controller essentially locks up and requires a restart to recover. Product Line TAC Vista, TAC INET Environment TAC Vista  below version 5.15 Xenta 527 using Controller LAN (RS-485) I/NET Cause Vista will poll I/NET for the past 1000 entries. Normal internal events consist of much less data than the I/NET events; 1000 I/NET events in one message make the message too large. The VSD Response too large error indicates Xentas max message size has been reached. TAC Vista ignores the error and repeatedly tries, leaving the Xenta 527 stuck in a loop. Resolution Polling I/NET for fewer events fixes this problem. The max number of events in one message has been adjusted down to 400. This change is included in TAC Vista revisions 5.1.5 HotFix 16 and later.

Issue Continuum Reports Suite installation issues. Example error message could be: "Unrecoverable Error!" "Alias 'CURRENT3' is not found" "Method: ALARMEVENTS.RUN_REPORT_BTN.CLICK" Product Line Andover Continuum Environment Continuum Reports Suite Cause Problems with installing and running the Report Suite Resolution When editing the "Continuum_Reports.dmp" file using Notepad.exe, WordWrap must be unchecked!  Unfortunately, opening "Continuum_Reports.dmp" and unchecking WordWrap is not enough!  When WordWrap is checked, you must uncheck and Exit Notepad.  Then Open "Continuum_Reports.dmp", edit and SAVE AS.  When WordWrap is enabled and changes are made, after you Save and reopen the file, you will notice that is corrupt and all the PE Codes is scrunched into one enormous line, instead of 550+ lines. Alternatively use a different editor, eg. Metapad or Notepad++ If after editing and importing "Continuum_Reports.dmp", you discover there is no Plain English code or the Programs run, but are stuck on "Init", or other PE import / run issues, this is the result of incorrectly performing the Replacement of the workstation Folder Name.  When the Workstation Folder name and Workstation Name is correctly replaced, the PE programs will import and run properly. After installing Continuum Reports, you should confirm that the installation directory, "C:\Program Files\Continuum_Reports" has Modify privilege enabled for all "Workstation Users". After a Continuum Reports run-time error, run the Windows Task Manager and confirm that the "Reports.exe" Process does not exist.  If it exists, End the Process. If Continuum Reports does not exit normally, temp files will be orphaned in the C:\Program Files\Continuum_Reports\Data directory.  Although orphaned Temp Files do not affect Continuum Reports operation, they occupy disk space.  Temp files have an underscore ("_") as the first character.  To remove orphaned temp files, make sure Reports.exe is not running and CAREFULLY delete those files that have an underscore ("_") as the first character. Continuum Reports needs to be installed using the Setup Application. The Setup Application needs to be run on every workstation and configuration administered locally. Before you install Continuum Reports, the current version must be uninstalled.  Typically, uninstalling and reinstalling doesn't solve any problems.  But when this is done, make sure to delete the directory C:\Program Files\Continuum_Reports\DATA before reinstalling Continuum Reports. Continuum Reports remembers the Continuum Database access parameters, including Server Name, SQL Username and Password.  After installing Continuum Reports, you will need to run "Reset_Password.bat" if the Continuum Database name is not "ContinuumDB", or if appears that Continuum Reports is not accessing the correct database. If the Multi-Facility Report Data Partitioning has been used (17.2e onwards) the Revision Level in the upper right hand corner of the window is Red.  This indicates that Restrictions were enabled.  Therefore the whole database may not be queried.
