Issue When opening a BACnet AnalogInput  from (the Blue) BACnet device side, the value of the object displays as 3 decimal digits by default. The format can be changed in the format field as desired, however when clicking the "Apply" button, an error prompt box pops up with the message "An attempt has been made to write a property defined as inaccessible through the BACnet  protocol write services". if the "Apply" buttonis clicked again, the error disappears and the format is been changed successfully. Product Line Andover Continuum Environment Continuum BACnet BCX1 B3s Cyberstation V2.02 and earlier. Cause Format is not a standard BACnet property, it is a Continuum attribute and when the format is changed Cyberstation sends a command to change the "present value" of the point in the controller. The present value of AnalogInput cannot be written so the error occurs. When clicking "apply" or "OK" for the second time Cyberstation only writes the attribute of the point in the database rather than the controller. Therefore we can get a successful change of format for AnalogInput by clicking "Apply" twice. For AnalogValue, the "present value" of  AnalogValue can be written in BACnet, so there is no error when changing the format of an AnalogValue. Resolution Ignore the error when making the change, click the "Apply" button twice after updating the "Format". Or upgrade to V2.03 where this issue has been resolved.

Issue Are 64-bit operating systems supported on the Andover Continuum product line? Product Line Andover Continuum Environment CyberStation webClient Cause Compatibility requirements for Andover Continuum with 64-bit operating systems Resolution Release 1.93 and earlier: For all machines with CyberStation or webClient software installed, only operating systems running in 32-bit environments are supported. 64-bit environments are not supported.  However, for the Database Server on a LAN system where no Cyberstation or webClient software is installed, a 64-bit version of Windows Server 2008 (SP2) or Windows Server 2008 R2 may be used on systems running V1.92 and above. These will also require Microsoft SQL 2008 running in 64-bit mode. Release 1.94 and later: Release 1.94 supports 64-bit Operating Systems, however, Microsoft recommends the 32-bit version of Office 2010 because it prevents potential compatibility issues with other 32-bit applications, specifically third-party add-ins that are available only for 32-bit operating systems. Please refer to the release notes for compatibility notes in specific versions.

Issue How to determine if SU (single-user), LAN, or WEBC (WebClient) license keys are required for your project. Product Line Andover Continuum Environment Continuum Cyberstation Continuum WebClient Cause The Engineer is unsure as to which Continuum License Keys are required for a new site or if additional Cyberstations or WebClient users can be added to an existing site. Resolution Depending on how large your system is and how many Cyberstations are required, you will have one of the four system configurations described below: A stand-alone system, which is comprised of up to three (3) PCs; (PC 1) Requires a SU key allowing SQL Express + Continuum. (PC 2) Requires LAN key allowing Continuum. (PC 3) Requires LAN key allowing Continuum. Note1: When changing from a LAN configuration to a SU configuration, an existing LAN key can be used in place of having to purchase a new SU key.) A stand-alone system with WebClient, which is comprised of up to three (3) PCs; (PC 1) Requires a SU key with WC1 or WC2 option allowing SQL Express + Continuum + one or two WebClient browser users. (PC 2) Requires LAN key allowing Continuum or no key allowing WebClient browser user connection. (PC 3) Requires LAN key allowing Continuum or no key allowing WebClient browser user connection. Note2:  In a stand-alone system there can be a maximum of 3 client connections; 3 Cyberstations OR 2 Cyberstations and 1 WebClient OR 1 Cyberstation and 2 WebClients. Note3:  When using this option of having WebClient running on the same system as the Cyberstation and SQL Server, make sure that the system has enough resources to adequately support these resource-hungry processes. A LAN system, which can be comprised of many PC's; (PC 1) No key required. Allows SQL Server only. In a LAN environment the Continuum Cyberstation is not installed on the same PC where SQL Server is installed). (PC 2) Requires LAN key allowing Continuum (PC 3) Requires LAN key allowing Continuum (PC 4) Requires LAN key allowing Continuum (PC 5) Requires LAN key allowing Continuum etc... A LAN system with WebClient, which can be comprised of many PC's; (PC 1) No key required. Allows SQL Server only. In a LAN environment, the Continuum Cyberstation is not installed on the same PC where SQL Server is installed. (PC 2) Requires WEBC key allowing WebClient on dedicated IIS server (up to 1, 2, 5, 10, 15, 20, or 25 WebClient user(s) licenses available). (PC 3) Requires LAN key allowing Continuum (PC 4) Requires LAN key allowing Continuum (PC 5) Requires LAN key allowing Continuum etc... Note4:  An SU key cannot be used in a LAN system as it does not allow a remote SQL connection. To connect to a remote SQL Server a LAN key is required.)   For more information on Cyberstation License Key part numbers and the different options available for these keys, see "CyberStation & web.Client v2.0 PA-00353" or similar on ExchangeOnline.

Issue Poor communications, communications failure or packet being corrupted Product Line Andover Continuum,EcoStruxure Building Expert,EcoStruxure Building Operation,Satchwell MicroNet,Satchwell Sigma,TAC INET,TAC Vista Environment Communications networks, BACnet MSTP, LON FT10, Infinet, Modbus RTU, Ethernet EMC (Electromagnetic compatibility) VSD Variable Speed Drive, VFD Variable Frequency Drive, Inverter Drive Cause Electrical Interference from Inverter (variable speed drives or VSD) Radiated or Induced RFI (Radio Frequency Interference) Resolution A VSD has the potential to create a large amount of electrical noise, to avoid causing issues it is vital they are installed as the manufacturer's instructions.  (Other devices also have this potential) Our systems are often used to control VSDs on fan motors, so if poor communications is found during the commissioning process, then try stopping all the fans in the area then re-testing the communications. A recent example was seen where LON FT10 communication was working ok until some VSDs were started, at this point LON devices and Object went offline intermittently. When all the VSDs were stopped the communication become completely stable. It was then possible to find which VSD was causing the problem and correct the VSD installation. In this case a LON analyzer would also have helped diagnose the issue.

Issue How to calculate total memory required for controller to store logging information for the required duration. Product Line EcoStruxure Building Operation, Andover Continuum Environment NetController (CX9900, CX9940, CX9680, bCX9640) InfinetController (i2xxx) BACnet Controller (bCX4040, bCX9640, b3xxx) Cause Need to know how much memory is needed per point to determine the maximum number of entries and minimum interval time that the controller can use. Resolution The general equation of calculating memory use for controller logging is as below; * Memory usage per point = { 8bytes + (4bytes * NumberOfLog) } In addition to that, each controller requires minimum 1~2KB of freemem after the controller logging memory allocated.  Regarding the log interval, if the point is being logged for controller only, you can set the interval in seconds unit.   But if you configure the point for ExtendedLog as well, the logging interval should be in minute unit. Again, if there many objects with one minute interval for Extended Logging, it will affect the performance of the Cyberstation and also increases the size of ContinuumDB dramatically in short period of time. In this case, consider increasing the log interval to 5 ~ 15 minutes for Extended Logging.

Issue The user is unable to log in to a WebClient session from a web browser even though the number of client session currently established is less than what the license provides for./p> After applying the Continuum Virtual License for WebClient, the ACCWebServerProxy indicates a maximum client seat count that is less than what the license specified.  Product Line Andover Continuum Environment Continuum WebClient Server Continuum Virtual Software License Cause In some cases, it is possible to apply two licenses to the same WebClient host.  When this happens the client seat count is dictated by the first license that was installed even though subsequent licenses may have a larger number of seats. Resolution If the license Key Type is SL Admin Rehostable, one of the licenses can be moved to another host temporarily while the remaining license is tested. Contact Schneider Electric Buildings Product Support for assistance in determining which license should remain on the machine and which should be moved to another host machine. If the license is not hostable contact Buildings Product Support.

Issue Need to replace or add an xP expansion module. Product Line EcoStruxure Building Operation Andover Continuum Environment xP Expansion Module  Cause When replacing or adding an xP expansion module does the controller need to be powered off? Resolution When replacing or adding an xP expansion module the controller must be powered off, i.e., hot-swapping is not allowed. Adding an expansion module to a controller requires the controller to be cold-started. After the cold-start the CPU light on the first xP module should blink once at a rate of about once every 2 seconds. This is considerably slower than the controller CPU LED it is connected to. If a second xP module is connected, it also has about 2 seconds between flashes, but it will flash twice indicating it has detected the second module.

Issue Care must be taken about the precedence of operators in Plain English programming to achieve expected results. The following PE program was created with the intent of monitoring how long a point has been in alarm and unacknowledged The user intent was to have the program increment  ‘TimeInALM’ for every minute the point has been in alarm without an ACK WaitOneMin: IfTS > 59 then Goto CheckALM CheckALM:   TimeInALM = TimeInALM + PSS\ACX2.48\Num1 Alarm1 = On and PSS\ACX2.48\Num1 AckTransToOffNorm <> 255   IfTimeInALM > 4 thenGotoAlertGuard ElseGotoWaitOneMin AlertGuard:   TimeInALM = 0   GotoWaitOneMin Instead of incrementing as was the intent, ‘TimeInALM’ kept toggling between 0 and 1. Product Line Andover Continuum Environment Continuum Cyberstation Continuum (All CXs) Continuum Plain English Cause The rules of precedence dictate that the + is done first then the AND. So this is what happens: TimeInALM = TimeInALM + PSS\ACX2.48\Num1 Alarm1 = On and PSS\ACX2.48\Num1 AckTransToOffNorm <> 255 We start with TimeInALM = 0 PSS\ACX2.48\Num1 Alarm1 evaluates to 1 and so does PSS\ACX2.48\Num1 AckTransToOffNorm So we have 0+1 = 1 ANDed with 1 = 1 Now TimeInALM = 1, so second pass is 1+1=2 ANDed with 1 = 0 So TimeInALM is now zero and the cycle repeats Resolution Use parentheses to enforce the order of operations.  This resolves potential ambiguities. TimeInALM = TimeInALM + (PSS\ACX2.48\Num1 Alarm1 = On and PSS\ACX2.48\Num1 AckTransToOffNorm <> 255) Here is the complete PE Operator Order of Precedence for reference.

Issue How to run the Import/Export Fixup Utility Product Line Andover Continuum Environment CyberStation Import Export Fixup Utility, I/E Fixup, IEFixup, IE,ImpExpFixupUtil.exe CX Controller, i2 Controller, Infinet Controller Cause Points not updating or alarms not coming in have resulted in PSS asking for the import export fixup utility to be run. Resolution Note: Before performing the steps listed below, make sure a database backup has been performed. Navigate to the \Continuum directory. The Import Export Fixup Utility is located here The filename is ImpExpFixupUtil.exe. Double-click it. It runs in a DOS window and when complete, creates a file in the format IEFixuptimestamp.log. In some cases the log file will open; in others it will be saved to the \Continuum directory.

Issue Minimizing network traffic when sharing data between Continuum Infinity controllers Product Line Andover Continuum Environment CyberStation All CXs All i2s, Infinet Controllers Cause Accessing a remote point’s attribute other than value is a point to point operation that generates extra traffic. Resolution Continuum controllers implement an Import/Export strategy in order to minimize network traffic when accessing the value of a point in a remote controller; this is in some ways similar to BACnet COV. When the value of a remote point is referenced in a PE program the system takes care of making sure the owner of the point sends the value to the subscriber(s) via the Import/Export system ONLY when the value changes. Consider the following PE program line… MyNum1 = RemoteCX\Num1 If a looping PE program sits on the line above no extra traffic is generated as the PE program gets the value of RemoteCX\Num1 from its local Import/Export table, information only goes on the wire when RemoteCX\Num1 changes value. The only problem here is that the Import/Export system ONLY works for the VALUE attribute, any other attribute requested from a remote object results in a point to point message on the network to obtain the requested attribute value. Consider the following PE program line in a CX controller we will call LocalCX NyNum1 = RemoteCX\Num1 size If a looping PE program sits on the line above a number of point to point messages would go on the wire every time the line executes. If there are many requests for attributes on remote objects a degrading in communications could take place. One way to avoid degrading communications as explained above is expose the value of the attribute in question by placing it in the value of a numeric object. Example: In RemoteCX create a numeric point (Num1Size) to hold the size of Num1 and use a PE program to set Num1Size Then the program in LocalCX will look like this… NyNum1 = RemoteCX\Num1Size Since the program is now going after the value attribute of Num1Size the import/export system will be used instead of point to point.

Issue The re-install of the Continuum system and security key is not being recognized. Product Line  Andover Continuum  Environment Continuum Cyberstation Sentinel Security Key Cause Driver not loaded Resolution Make sure the antivirus is not running on installation. If so, disable and re-install Continuum, or try to reinstall the Sentinel Key driver. The Sentinel Key driver is located in "\Continuum\ISSetupPrerequisites\{1F0227D8-C348-45F0-9789-1DEE3E8C5889}" directory and is an executable that can be run to install the driver. Sentinel Key drivers can be located on their website: http://www.safenet-inc.com/support-downloads/sentinel-drivers/ At times, the removal and reinstall of the driver still don't recognize the key even when it can be seen in another PC. If that is the case then do the following: Go to http://www.safenet-inc.com/support-downloads/sentinel-drivers/ and download SSDCleanup and run it. This will do a clean removal of sentinel drivers on the PC. Reboot and then reinstall the Sentinel driver from \Continuum\Install\Sentinel directory (SSDv7_xx.exe) Test multiple Windows accounts. There can be restrictions placed even on local admin accounts that interfere with reading the key.

Issue Where is graphic information stored in Continuum? Is any graphic information stored in the controller. Product Line Andover Continuum Environment Continuum Cyberstation Continuum webClient Server Cause Need to know where Continuum Graphic information is stored. Resolution While during the Continuum installation process, pin files, image library files and background images are placed in the NewGraphicFiles folder on the workstation on which Cyberstation is installed, these files can alternately be stored on any network share.  Each workstation must have the location of these files defined in Pinpoint under View>Options.   The graphic information is stored in the dbo.Panel table in ContinuumDB.    The Graphics folder paths that are set from 'View\Options' are unique to each Cyberstation and are stored in the device table of the ContinuunmDB on the corresponding row of the appropriate Cyberstation in columns PPBackgroundsFolder, PPGraphicsFolder and  PPGraphicsLibraryFolder  No graphic information is stored in the controller
