Issue Changed MNL controller application engineering units to Metric (Celsius temperature) using the hardware wizard. After downloading the modified application, the setpoints and setpoint range on the MN-Sx sensor are still reading in degrees Fahrenheit. Product Line TAC IA Series Environment I/A Series WorkPlace Tech Tool software. I/A Series MNL I/A Series MNB Cause Changing the engineering units from English to Metric using the Hardware Wizard does not alter the values already configured for the setpoints or setpoint ranges in the MN-Sx sensor. The standard applications have predefined setpoint values and setpoint ranges based on the application type and MN-Sx type. These setpoints and setpoint ranges are configured with values appropriate for the operation of the controller using English engineering units (Fahrenheit temperatures). When the controller's engineering units have been changed to Metric, the appropriate temperature setpoint values and temperature setpoint ranges must be entered via the appropriate screen of the Resolution After using the WorkPlace Tech Tool Application Wizard to change the controller's application engineering units, the entered values for any setpoints and setpoint ranges must be reentered as numbers appropriate for the new engineering units. The application template files are configured for English (standard) engineering units with temperatures in Degrees Fahrenheit. For example, the default space temperature setpoint is 70 degrees. By default, the controller is configured for English engineering units, resulting in the space temperature setpoint is 70 degrees Fahrenheit. Changing the controller engineering units to Metric will result in the default space temperature setpoint being 70 degrees Celsius unless the setpoint and setpoint range is redefined using the Hardware Wizard.

Issue There are a number of reasons that RPC error occur on Cyberstation and troubleshooting steps are needed Product Line Andover Continuum Environment Continuum Webclient Windows XP Window Vista Windows 7 Windows Server 2003 Windows Server 2008 Cause RPC (Remote Procedure Call) errors happen on Cyberstation when the connection to the SQL database is not available Resolution There are many reasons that RPC errors can occur. A Google search of RPC errors will indicate that many applications have similar issues with these errors. An RPC error on a Cyberstation means that it has lost connection to the database for some reason and you will need to restart Cyberstation in order to recover. Below is a list of things to check when dealing with RPC errors on CyberStation.   Multiple Cybers Does the issue occur on multiple Cyberstations? Database Does the issue follow the database? i.e. load the database onto a test server or try a test blank database. Were some new objects recently added to the database when this started happening? Does reverting to a backup stop the errors? Increase Virtual Memory Right Click on My Computer> Properties> Advanced System Settings> Under Performance select the Settings button> Advanced tab> Under Virtual Memory click the Change button Recommended is 4096 Network disruption or slowness Networking  -  Verify all aspects of your networked environment.  This includes, but not limited to, slow networks, possible problems with your network interface card (NIC), cabling issues, switch/router issues, busy networks.  As you can see from the above definition of what RPC is it can be heavily reliant on the stability of the network and all it’s interfaces. Continuum does not support DHCP Multiple NIC cards – ensure there is only 1 NIC card enabled. No all NIC cards are created equal. Connections issue can be caused by an integrated NIC card of low quality. There can be settings within the NIC card itself that could affect consistent communication. Check the manufacturers website for details. Verify that there is no duplication of IP addresses on the network. Pull a cable and ping the address, if you still get a response there are 2 devices with the same IP address. WINS -  Verify your WINS settings and make sure there are no issues with the WINS Server.  This is known by Microsoft to cause RPC errors. DNS - Verify your DNS settings and make surer there are no issues with the DNS server.  This also is known by Microsoft to cause RPC errors. Verify that  the "TCP/IP NetBIOS Helper" service is running. Check and see if “File and Print Sharing” is enabled.  There are references in a lot of online articles, on RPC, problems that turning on “File and Print sharing” resolves RPC errors. Ping and SQL Is the SQL database still available to Cyberstation? From a DOS prompt> Ping IP (SQL Server) –t (continuous) Ex. c:\> ping 192.168.1.5 –t Note the number of responses as well as the time in milliseconds to respond. A local SQL server would usually be under 100ms. Check resources on the SQL Server (CPU, I/O Read/Write, memory usage, etc.) Windows Server 2003 Network card setting (This setting isn’t available in Windows Server 2008) Shut Continuum down on the machine having the problem. Start>Settings>Network Connections>Local Area Connections>Right Click and select Properties> Click on File and Printer Sharing for Microsoft Networks>Click Properties button> Select 'Maximize data throughput for network applications'. (Default is Maximize data throughput for File Sharing) Ok through all the screens and start Continuum and see if this makes a difference. XP/Vista/Windows 7 Start> Settings> Network Connections> Local Area Connection> Properties> Advanced tab> Windows Firewall - Click the Setting button> Click the exceptions tab Verify that File and Print Sharing is selected. File and printer sharing are disabled by default with XP SP2. There is no network throughput option in XP, Vista or Windows 7 like there is on Windows Server 2003. Windows Event Viewer Take a look at the Windows Event Viewer Application Log (Start> Run type ‘eventvwr’ or Launch Windows Control Panel> Administrative Tools> Event Viewer Examine the events and look for RPC error indications in the details. There may be a pattern of which executable is causing the errors. You may also see informational events that indicated momentary disconnects. A large number of these can indicate an issue with the Cyberstation being able to connect to the database consistently in a timely manner. Monitoring tools Run an acctrace.exe (C:\Program Files\Continuum) and a wireshark capture at the time of the RPC error to see the Continuum and network processing going on at the Cyberstation. Windows Process Monitor may also be helpful in seeing which process is having trouble. http://technet.microsoft.com/en-us/sysinternals/bb896645 Check the system for SpyWare and/or Viruses. Workgroup versus Domain connection An excerpt from the Continuum System Admin manual In a LAN Configuration, the Continuum CyberStation must be in a “Microsoft Domain “ type installation. This is because the Continuum CyberStation will use Named Pipes Interprocess Communication System (IPC). This is accomplished with Windows remote procedure call (RPC). In a Microsoft Domain model installation, once the session is established between the Continuum Cyberstations Client(s) and the SQL server it is a persistent connection once authentication is established.   In a Workgroup installation, the database connectivity session is re-authenticated and re-established for each database transaction. This results in much slower performance and an inconsistent connection. If you are running a LAN system using Windows 2003 server SP2/R2 and SQL 2005 try disabling the TCP Chimney Offload feature by following the below. Disable the TCPchimney setting on the SQL server and application server Windows 2003 SP2 comes inbuilt with a new network scalability pack which is supposed to accelerate the Windows networking stack. But this setting may not be compatible with all the network cards and it could pose connectivity issues as well. For more information you can refer to http://support.microsoft.com/kb/912222 http://support.microsoft.com/kb/942861   To disable this feature please take the following steps on both the SQL Server and application server.   Open up a command prompt on the machine. Run the following command: "Netsh int ip set chimney DISABLED" Change the values of the following registry keys to 0 a. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ EnableRSS   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\ EnableTCPA Reboot the machine after the above changes. ==========================================================   Disable SynAttackProtect on SQL server: Windows 2003 Sp1 and Sp2 introduces this new feature which monitors processes getting high number of connections and if it detects that too many connections are being made, the connections will be rejected. Click Start, click Run, type regedit , and then click OK. Locate and then click the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters On the Edit menu, point to New, and then click DWORD Value. Type SynAttackProtect , and then press ENTER. On the Edit menu, click Modify. In the Value data box, type 00000000 . Click OK. Quit Registry Editor. Sound Card In some cases it was found that the built in sound card is causing the problem. If your not using WAV files for alarms then try disabling the integrated sound card in the BIOS.  If WAV files are being played then try disabling the integrated sound card and put in a PCI sound card. There have also been problems with OEM versions of the Operating system of the client machines.  A lot of vendors, like Dell, add additional applications to the systems they ship to assist them if they need to remote into the computer for troubleshooting purposes.  It is strongly recommended that these OEM versions of the Operating System is removed and install the system from a genuine Microsoft installation CD. Go to Control Panel-> Administrative Tools -> services, click with right mouse button Remote Procedure Call -> click properties. remote procedure call properties window is now open, go to recovery and you´ll see: First failure, second failure, subsequent failures -> choose : restart the service. In this setup the system will automaticaly restart RPC when something shuts it down. Check all your Firewall settings.  If possible turn off the firewall for testing and see if the problem goes away. Check to make sure there are no ports being blocked that the RPC Server uses.  See KB 908472 (http://support.microsoft.com/kb/908472) details the steps for specifying the RPC port range.  Also, be aware of the consequences of reserving the RPC ports. This has the potential to break other applications that assign ports in this range. KB 812873 discusses this, too. http://support.microsoft.com/kb/812873 Make sure all Peripheral devices like Network cards, Video cards, Sound Cards, etc. have the latest drivers for them installed. http://support.microsoft.com/kb/913384 Control Panel > AdminTools >Services and selected the Properties for Remote Procedure Call (RPC)  In the Log On tab, they changed the Log on as: to the Local System Account.

Issue Solid red light Blinking red light Blinking green light Product Line TAC Vista Environment Xenta Programmable Controllers Xenta 280, 281, 282, 283, 300, 301, 302, 401, 401:B Cause The indicator lights on the face of the Xenta controllers can help explain the state of the controller with different actions.  Resolution There are two LED indicators – one red and one green on the Xenta programmable controllers.   The red service diode is primarily an error indication. It also lights up if the Service pin is activated. A solid red light usually indicates that the hardware has failed.  Please see a few simple steps to deactivate the solid red light below. Use a reset dongle to wipe the controller then reinstall the firmware and menta program. If the controller is the group master you might try to assign a different controller to group master.  This method has not been proven but has worked before during internal testing. NOTE: The hardware may need to be replaced if the solid red light continues after these steps. If the red indicator light is blinking once per second this will indicate a non-configured node. If the controller has been commissioned you might try to decommission the controller and try again. If the red indicator light is off this would indicate that it has been commissioned and added properly to the network.  You should not see the red indicator light if the controller is working properly. The green status diode blinks once per second to indicate that the program is running properly.

Issue Fluctuating temperature readings where they jump up to +327 randomly. Product Line Andover Continuum Environment Continuum controllers i2866-V Cause Readings like that are usually caused by wiring or power issues. There was also a Firmware fault that caused this in an old version of the i2866-V Firmware. Resolution Confirm the following wiring considerations:   That your input and output cables shield is wired to Earth ground at one end of the run only (preferably the controller chassis). That your controllers power supply is earthed on the secondary side of the 24vac transformer to ensure a proper controller ground to Earth. Confirm that the power supply is not being shared with any field devices, especially field devices feeding inputs back into the controller. One way to troubleshoot if it is a cabling or controller problem is to replace the sensor cable with a 10K ohm resistor. See Temperature inputs not reading the correct value for details. Also, in i2866-V controllers with firmware versions less than v3.501049, temperature inputs could randomly go to +327 when Analog Outputs were changing value frequently. Uprev your controller. See TPA-BOST-09-0007.00 for details.

Issue Procedure for installing PCC-10 or PCLTA20/21 network cards on a Windows 7 PC Product Line TAC Vista Environment Vista Menta LonMaker Windows 7 Cause Installation procedure differs from earlier versions of driver software. Resolution The PCC-10 and PCLTA-20/21 network cards work on Windows 7 (32 bit) PCs when the OpenLDV 4.0 driver is installed. This driver is installed automatically when Lonmaker Turbo SR4 is installed, but if this version of Lonmaker is not present the driver must be installed manually.  The latest drivers can be obtained from the Echelon download site: http://www.echelon.com/support/downloads Note: The PCLTA-20/21 card is only supported on 32bit windows operating systems. For 64bit systems use a NIC-USB as mentioned in this article: Computer will not recognize NIC709-USB. Install the drivers before fitting the card in the PC. Please note that OpenLDV4.0 requires .NET Framework 3.5 SP1.  This is not included as a subset of .NET Framework 4 or later, so must be installed separately.  You can have multiple versions of .NET framework installed on the same PC. The following description is for the PCLTA-21 but the PCC-10 is similar. To change the system image or perform diagnostics, you must go to Control Panel and open the Lonworks Interfaces application: Click Start on the taskbar, point to Settings, click Control Panel, and then open the LONWORKS Interfaces application. Click the PCLTA-21 interface in the list view on the left side of the user interface to display the interface's properties in the details pane in the right side. The details pane lists the PCLTA-21 card's system image and transceiver properties. To change the system image used by the PCLTA-21 card, click anywhere in the NI Application property, click the box to the right, and then browse to and select the desired system image from the LonWorks\Images\PCLTA21 folder. Note: For more information on configuring, testing, and diagnosing the PCLTA-21 network interface, see the LonWorks Interfaces online help.

Issue How long can the power to AS be interrupted Product Line EcoStruxure Building Operation Environment PS Power Supply Automation Server Cause Question regarding the AS and the power supply module. If the power is interrupted from the 24VAC power supply for say, 100 milliseconds, will the power to the AS be interrupted? There is a cold cap in the PS, and how long does it maintain power supplied to the AS? What about the RTC?   Resolution The power to the AS will be interrupted if there is a 100mS main power fail. The AS will then save the server cache. When the power returns the AS will make a restart that will take approx. 2 minutes. The AS Power supply fully complies with the IEC 61000-4-11 standard and can withstand voltage dips, with a 20mS dip and a 0% residual voltage.  The Power-fail process: When the AS loses power the super-cap keeps the AS alive for 15 seconds. 10 seconds of it dedicated to power-fail process to flush all the data that that are currently in the RAM to the SD card(That data can be anything with any value they have before power-fail). When power comes back that data is retained and are stored in appropriate place on the SD card. Real-Time-Clock(RTC) is maintained when the AS loses power by a dedicated capacitor which backs up the RTC chip for a minimum of 30 days in the absence of power since there is no battery in the AS.

Product Line EcoStruxure Building Operation Environment Project Configuration Tool, PCT Cause Any change made in PCT increases the size of PCT project folder. This is by design and it is a normal behavior of PCT. The reason for this is that a project is a virtual machine using a dynamically allocated image that grows when memory is needed, but the image will not shrink when something is deleted.  Resolution The only way to reduce the folder size of a project is to backup all servers in the project, create a new project, restore the server backups to the new project and then delete the old project.

Resolution FTT-10 LON network wiring must be installed using Echelon-approved wire.  The most common type of wire used is described as Category 4  cable.  This wire is normally unshielded stranded twisted-pair 22AWG (0.65mm).  An example of this wire is the W221P or W222P series cable from Connect-Air International (http://www.connect-air.com).  This type of cable is normally available both in plenum rated and non-plenum rated types.  Consult the job specifications to determine if plenum-rated or shielded cable is required. The LON network can be wired using "Free Topology" or "Bus Topology" wiring segments.   1.  BUS Topology Guidelines BUS Topology LonWorks wiring extends from device to device (daisy chain format) with no branches or stubs. A LON-TERM-2 terminator must be installed at each end of the LON bus. When using standard Category 4 LON cable with the recommended terminators, the bus may be up to 4593 feet (1400 meters) in length. When extending LON wire to the MN-Sx sensor base in a bus topology network, the sensor base must be wired as part of the daisy chain and not as a stub connection. 2. FREE Topology Guidelines Free Topology imposes essentially no restrictions on the layout of the network -- some controllers may be wired point to point and others branching from a common point.  The free-topology LON network must be terminated at one point with a LON-TERM-1 terminator. When using standard Category 4 LON cable, the total wire length in a free topology LON network may not exceed 1641 feet (500 meters).  In addition, the longest wire path between any two controllers on a free topology LON network may not exceed 1312 feet (400 meters). 3. Common LON Network Wiring Guidelines LON wiring can not be part of an active bundled telephone trunk even if the telephone trunk is wired with Category 4 wire. Shielded Category 4 wire may be used in high EMI/RFI environments.  The shield must be wired continuously and grounded through a 470 Kohm resistor at one end. LON wiring must not be bundled with or housed in the same conduit as controller I/O and power wiring.  4. LonWorks Network Wiring and Addressing Guidelines When the number of controllers on a LonWorks network exceeds 60, the network must be split into segments with not more than 64 controllers or devices per segment using LonWorks Repeaters or Routers.  When counting the controllers and devices on a LonWorks network segment, a LonWorks Network Interface Device and the repeater itself must be included in the device count in each segment. In a LonWorks network containing repeaters or routers, each LonWorks network segment must be properly terminated, as described above. Domain / Subnet / Node addressing is used when configuring the LON controllers. A LonWorks Subnet consists of a series of LonWorks controllers all configured within the same LON Subnet number. A single LonWorks Subnet can have a maximum of 127 device and controller Node addresses.  This Node address count includes the LonWorks Network Interface, all controllers on the subnet, and repeater and/or router node addresses.  An allowance is typically made for additional addresses to be used by LonWorks tools connected to the Subnet.

Issue Is it possible to rebuild a  Continuum Database from the BACnet controllers in the field? Environment Continuum BACnet Cause The SQL server has failed and there are no acceptable backups of the ContinuumDB to restore once the server has been repaired. The controllers in the field are still functioning and have valid application programming. Resolution Although it is possible to recover the database from the field controllers, the best method of recovery is to have a recent backup of the ContinuumDB and to restore this once the Server gets fixed up. You can load the data from your field controllers into a new Database. Note that all objects will have their name now set the same as the alias, as this is what is stored in the controller. To load the bCX and attached b3's, do the following with a blank database. 1. Create and configure a network folder. 2. Create and configure you bCX1 device object to bring it online in the Infinet view. 3. Right-click on the bCX1 object in the Infinet view and select "Send to -> Database". 4. This will save the controllers database to a temporary dump file on the Workstation then load from this dump file, creating the objects and populating the database. 5. When done, this should have also found all b3's that were defined in the bCX1 and loaded their contents as well. 6. This will load the BACnet objects as well as the Infinet objects. Note: Recreating the Network from the field does not recreate any objects that were stored in Workstations or in folders off the root. These objects; such as listviews, programs, reports, etc...; are not stored in the controllers and will need to be recreated. 

Issue Steps to backup within StruxureWare/EcoStruxure Building Operation Product Line EcoStruxure Building Operation Environment StruxureWare/EcoStruxure Building Operation site with AS and/or ES Backup, Automation Server, Enterprise Server, Workstation, .xbk, xbk, backup set, db backup, db_backup Cause Must an AS or ES be stopped in order to do a full backup? Is a raw copy of the database folder from within Windows Explorer sufficient for backing up an ES?  For instructions on how to restore a backup in StruxureWare/EcoStruxure Building Operation, see How to restore a StruxureWare Building Operation server backup set. Resolution Concerning the backup and comparing SQL to the proprietary database that StruxureWare/EcoStruxure creates begs the question, are these backup complete? StruxureWare freezes the database while a backup is in progress in different ways. For configuration changes, StruxureWare Building Operation queues up the changes until the backup completes. For historical data, StruxureWare Building Operation buffers the data based on the limits of the buffer size. A stop of the ES is not necessary, nor is a stop of an AS. Because of this freeze and buffering, the data is put into that backup folder referenced in the pdf you sent. Three rules to remember: Restores of backups must be same software revision Do not rename the backup set A StruxureWare/EcoStruxure Building Operation backup should not be renamed after it has been created. When creating a backup, give the appropriate prefix to the standard name format.     The backup file will be shown as below. Should the backup name need to changed, then either create a new backup, or, zip up the backup using the new name.   Backups default to every Sunday morning 1:00am Here is the procedure for backing up an AS or ES: In Workstation, in the System Tree pane, select an Automation Server (AS) or Enterprise Server (ES) On the Actions menu, click Backup. This opens the Backup Options window In the Include column, select the servers that you want to include in the backup In the Backup content column, select the type of data you want to backup for each server: Select All Data to back up both the historical and configuration databases. This combined option protects the configuration, historical data, and custom object type data for a specified date and time Select Configuration only to back up the configuration database and custom object type data. This data option protects the configuration data for a specified date and time In the Backup set description column, type a brief description up to 255 characters to help identify the content of the backup Click Backup Verify that each backup succeeded and click Close Backup Files of ES: The backup data files are stored in the C:\ProgramData\Schneider Electric StruxureWare\Building Operation 1.X\Enterprise Server\db_backup\LocalBackup or  C:\ProgramData\Schneider Electric EcoStruxure\Building Operation 2.X\Enterprise Server\db_backup\LocalBackup   Backup Files of AS: Login to AS from WorkStation and navigate to System > Backup and Restore > Backup sets> Local. Then Right-click on the backup file and Save To... (then select a folder on your HDD) Note: Let this not be confused with the 'Starting a Project Tutorial [101248].pdf' in section 5.1 page 44, where it describes the user simply doing a raw copy of the database folder from within Windows Explorer. This can be mistaken with the orderly backup that uses the inbuilt StruxureWare backup facility. This copy procedure described has no chance to freeze the database. The user can just do it at any random time and StruxureWare has no idea that the copy has been made. A sample database should be created using the Backup/Restore functions of the system, not by just doing a raw folder copy as the server may be in the middle of transactions to various files in that folder. A copy of this folder could be used, but only while the SE.EnterpriseServer.exe process has been stopped. However, it is recommend using the system’s backup facility to accomplish this (Not all items are backed up such as Alarm data. The Backup/Restore help section of StruxureWare Building Operation Guide discusses what is and isn’t backed up).
