Issue BACnet binary value objects will pulse an Infinity output when they are used to set its value instead of turning it on. Environment BACnet binary value object Infinity output Cause People who are unfamiliar with programming for BACnet controllers may find it difficult to code their programs based on BACnet point values. Resolution When coding for Andover BACnet controllers, it is important to consider the differences between BACnet and Infinet point types. If you create a Numeric (configured as a binaryvalue) in a b3, b4 or BCX BACnet controller and you import that value into another controller for use in controlling an Infinity output, the output will pulse once on change of state (equivalent to output=1)and then shut off. Also, when changing the binaryvalue from inactive to active will cause the output to pulse as well. When an Infinity output is set to Digital The default display format is $###. When the display format has been set to $### , values greater than zero will be displayed as ON, zero value will display as OFF and values less than zero will display as -ON if it is a tristate output. Changing this display format to ###.## will show the exact value of the output. On/Off or the analog value sent to it. Use the blue BACnet folder and check that the source point is defined as a Binary Value and the Output is a Binary Output. If an Infinity Numeric was originally created as the default Analog Value and sent to database in the BACnet folders, it will have to be deleted and re-sent to database to get it into the correct Binary Value folder. Example 1: The program below in the importing controller is a one-line looping program as follows: output1= B4/B3/BinaryValue A possible use for this would be a global occupancy point being used to turn the lights on. Example 2: Write a PE program to copy a binaryvalue (BV) to a binaryoutput (BO). Set the BV to Inactive. Observe that the BO is Inactive. Set the BV to Active. Observe that the BO pulses for one second. In order to import BACnet Binary values into another controller and use these points to drive an output on that controller you must use the BACnet point objects in your Plain English program as per below: "Full BACnet Path" Binary Output Name = "Full BACnet Path" Binary Value Name This will ensure that when the binary value is true, or "1", that the Binary output will go to "ON" and not pulse for 1 second.

Issue What are the data sharing differences between the Wireless Infinet and the Hard Wired Infinet? Environment Wireless Infinet Hard Wired Infinet Cause Information on what is like to implement a wireless Infinet bus verse wired Infinet bus. Resolution Import/Export differences between a Wireless Infinet bus and a Wired Infinet Bus Below outlines what the differences are between a Wireless Infinet bus and a Wired Infinet bus when it comes to imported and exported values. Note: A point that is flagged as Exported will send it’s value out on any bus, wired or wireless, only when the point value changes. If the point value keeps changing rapidly, then every time the value changes it will be sent out on the bus. If the point value only changes rarely it still follows the same rule. It will only send the it’s value out on the bus when it changes no matter how often a program calls for the value. Programs that create an Import/Export relationship with the format PointA=ControllerB\PointA. Wired Infinet In a wired infinet bus when a point that is flagged to be exported changes it’s value it’s value will be broadcast as a single message on the Infinet bus. Any controller that hears that broadcast and has an Import/Export entry for that point will grab the value off the wire and update it’s Import/Export table. If a controller that needs that value does not get it due to Infinet bus problems then that controller will not update it’s Import/Export table and will miss the point value update. Again the above scenario is for a hard wired Infinet bus. Wireless Infinet In a wireless infinet bus when a point that is flagged to be exported changes it’s value it’s value will be sent as separate messages to each controller that has in Import/Export entry for that point. For example if a point is used on 10 different controllers and the point is flagged for export and also the point value changes then ten separate messages will be sent out, one to each controller. The for each one of those 10 messages the originating controller is expecting an acknowledgement back from the destination controller. If the sending controller does not get the “ACK” message it will retry sending the message again every 3 minutes until it does receive and “ACK”.   Programs that cause a re-transmission of a point that is flagged as exported with the format Set PointA Refresh=True. Wired Infinet In a wired infinet bus when a program sets the refresh attribute of a point equal to true then it will send out a single broadcast message on the Infinet bus. Any controller that requires that point’s value will grab the message off the bus and update it’s import/export table. This will send the value of the point out onto the bus regardless or whether the point value changes or not. Wireless Infinet In a wireless infinet bus when a program sets the refresh attribute of a point equal to true it will send individual messages to each controller that has an Import/Export entry for that point. For example if a point is used on 10 different controllers and the point is flagged for export then 10 separate messages will be sent out on the bus to each of the controllers that require that point value. For each of those 10 messages the originating controller is expecting an acknowledgment back from each of the destination controllers. If the sending controller does not get the “ACK” message it will retry sending the message. NOTE: In item 2 you need to be very careful if you are using a refresh program. When using refresh programs you do NOT want to make them looping. You especially do not want to make them loop through setting the refresh to true. A simple fall through program that is triggered off the Minute system variable should be fine. Also remember that a refresh program is a workaround for an underlying bus problem. This holds true whether it is a wireless bus or a wired bus. Since Wireless Infinet I/E is a guaranteed delivery, DO NOT use refresh programs in Wireless Infinet. The additional network traffic can choke the network and it is totally unnecessary. It is also important to put thresholds on exported points to avoid overloading the wireless network. If a wireless point is exported to many other devices, especially on another network whether wired or wireless, you should mirror that point in the BCX and let the BCX distribute it to the other network, by having the other devices reference the mirrored point.   Alarms being sent to the front end. Wired Infinet In a wired infinet bus when a point goes into alarm the alarm message will be broadcast as a single message to the BCX. If there is a problem with the bus, ie substandard installation, grounding problems, etc… , then there is a possibility that the alarm message does not make it to the BCX controller. Wireless Infinet In a wireless infinet bus when a point goes into alarm the alarm message will be sent as a point to point message to the BCX. If the sending controller does not get an “ACK” message from the BCX then the controller will retry sending the message again every 3 minutes until it does receive an “ACK” message from the BCX. Important note: Any point that has an alarm attached is tagged for export. This means that every change of the point's value will cause an export, even if the point is not in alarm. If you have points that change their value often you need to put a threshold on these points even if they only have an alarm attached on a wireless Infinet to avoid excessive traffic.

Issue Extreme care must be used when using PE programs to perform an automatic flash backup on a controller Product Line Andover Continuum Environment Infinet Controller BACnet Controller Cause An incorrect code in the program can cause issue to the controller and require a full reload. Resolution BEWARE of PE programs that set the flag to flash a controller Infinet and BACnet controllers that have the ability to have their objects backed up to flash and running a program to reflash them when the application data changes should be used with extreme caution. If you accidently created a program that looped and continuously wrote Accstatusbackup = accbackupnow and tried to change the application data such as creating a point or editing a program you will receive an error stating "OMS database not currently available (Backing Up)" This type of program is very bad, and can reset the controller requiring a full reload. This is not to say that such programs shouldn’t be created to reflash a controller when needed, just create them as a fall thru or stop the program at the end of execution and have them triggered ie... a certain time of the day and test to see if there needs to be a reflash ie... If accstatusbackup = accbackupneeded then Accstatusbackup = accbackupnow Endif Also keep in mind that flash memory circuits are rated for a maximum of 100,000 write operations and there is an automatic software based circuit breaker that will set the accstatusbackup to accbackupdisabled when 10,000 writes occur. This should be considered a safety net that the controller has been flashed 10,000 times, that would be a good point to ask "WHY". You can reset this by setting the accstatusbackup = accbackupenable and you’ll be able to continue to write to the flash. It would be a good practice to have a numeric that is alarmed to notify in the event of the controller excessively writing the flash. This number could be whatever you think your threshold for writes should be ie.. if you wanted to know when the controller has been flashed > 20 you would know that something is probably happening and maybe you should address it.

Issue A PCI I/O board added to allow a parallel port for a security key is not recognized by the key. Environment Continuum Windows XP Windows Vista Windows Server 2003 Windows Server 2008 Cause The default setup for the Sentinel driver does not configure the PCI port Resolution After adding a PCI I/O board to allow a parallel key, the security key is not recognized. Even if a printer works on this parallel port and another machine reads the key perfectly, the security key does not work. Uninstalling and reinstalling the Sentinel driver does not make a difference. The Sentinel driver needs to be configured to allow the parallel port to be accessed via the PCI bus. By default, only the ISA and USB port types are shown. Follow these steps to add the port for the installed PCI board: From the Control Panel, double-click the System icon to open the System Properties page. Click the Hardware tab and then the Device Manager Button to open the Device Manager. Click the + sign next to Ports (COM & LPT) to expand the tree. Double-click on PCI Card (LPT1) to open the property sheet for the PCI adapter. Click on the Resources tab to see the resources used by the adapter. Under Resource Settings, make note of the first number in the range of the first line. Ex. I/O Range 0378-0374 (the number to make note of is 0378) Next, Start the driver configuration utility, SetupSysDriver.exe. It is usually located at C:\Program Files\Rainbow Technologies\Sentinel System Driver Click the "Configure Driver" button, then click the "Add" button. Enter the I/O address of the PCI parallel port adapter into the "Bus Address" field. Ex. 0378. For Port type select PCIbus and Click on OK It will show that a User Created port has been added at address 0378. The Sentinel System Driver should now be configured to use the Parallel PCI adapter.

Issue Are B-link or Infilink repeaters required every 32 nodes on an RS-485 bus when using i2 or b3 controllers? Infinet 1 controller had this requirement Environment Continuum Cause Infinity version 1 controllers required a repeater every 32 nodes. i2/b3 controllers do not have this same node count requirement. Resolution If you are going to be using i2/b3s with no 3rd party bacnet controllers on the segment, it’s less than 4000ft with approved cable, the runs are totally daisy chained without any "Y's" or "T's" in the network runs, then no Infilink/B-link repeaters are needed. The reason for this is that Continuum uses 1/10th load transceivers allowing the full 127 nodes to be used. If you are mixing b3s with 3rd party non-Andover controllers or mixing infinity version 1 infinet controllers with i2s, then you will need a repeater every 32 nodes and every 4000ft. If the distance exceeds 4000 ft, you will need a repeater.

Issue Description of LED patterns on access readers, and how to change them Product Line Andover Continuum Environment Continuum site Cause Description of LED patterns on access readers, and how to change them Resolution How to control LED patterns on access readers ****For all Continuum controllers that support access control and modules except AC1 and AC-1A**** NOTE: AC1 and AC1A only support the Alternate LED pattern. Card Reader LED Patterns The LED pattern of the card reader is determined by the creation of an InfinityNumeric called AccessLEDPattern. TAC LED Pattern (AccessLEDPattern=0) This pattern is transaction based, meaning the reader LED indicates the state of the access transaction. Solid Red No door configured for this reader channel. The system will not process any transaction coming from this reader. Solid Green Door configured on this reader channel. System is ready to process an access transaction. Solid Red for 3 seconds following an access transaction Invalid attempt. Rapid flashing following an access transaction Valid access Slow flashing following an access transaction System is waiting for information needed to process the transaction. For example, transaction is being processed (remote validation) or the system is waiting for user entry. (PIN needed after card swipe.)   Alternate LED (Default) Pattern (AccessLEDPattern=1) This pattern follows the state of the door lock itself. This is the default LED pattern.  Solid Red Door is locked Solid Green Door is unlocked Rapid flashing following an access transaction Invalid attempt Slow flashing following an access transaction System is waiting for information needed to process the transaction. For example, transaction is being processed (remote validation) or the system is waiting for user entry. (PIN needed after card swipe.)   The above LED patterns are the most commonly used.

Issue SNMP Flashing options for Netcontrollers and BCXs Product Line Andover Continuum Environment All Continuum master controllers Cause Documentation Resolution BCXs & Netcontrollers can be in 3 states: SNMP Standard is how all controllers are shipped by default. This means that the controller model and some other object info can be obtained via SNMP. SNMP Alarming Enabled means Standard SNMP as well as SNMP Alarming is enabled in order to send alarms to a network management system. This is a paid for option either initially when the controller is ordered or by contacting repair. To enable this option in the field, repair sends a file and instructions after payment. SNMP Disabled means that no SNMP information will come from the controller. Upgrading controllers with future firmware versions Depending on which SNMP option state the controller is in will determine the application flash that should be used going forward. Selecting the incorrect file can disable or re-enable SNMP options. Netcontroller v1.5300x SNMP Not Set means no SNMP options will be changed when upgrading firmware v1.5300x Standard SNMP means use with Standard SNMP (default) v1.5300x SNMP Alarming Enabled means use when SNMP Alarming is enabled (Not Set could be used also since it will not change the enabled option) v1.53 SNMP Disable means this will disable All SNMP traffic, Standard and Alarming BCX Use the default firmware upgrade after SNMP is enabled. If you use the BCX SNMP Disable flash files and then upgrade to a newer version of firmware, you will have to run the disable flash file again to disable SNMP. NOTE: The flash files used to disable SNMP are posted on The Exchange. Note2: If the flash file doesn't enable the options because it was sitting at resetting controller,  Reload the controller which will force a reset and then try the flash file again.

Issue Webpages were able to be viewed from controllers in the past but no longer work. The controller can be pinged which indicates that it is online. Product Line Andover Continuum Environment B4920 BCX 99xx Windows OS Cause If running the latest versions of Microsoft Office, there are a lot of extensions installed in the registry under accepted documents which create a very long string for a HTTP request. Resolution In a test environment, Microsoft Office suite 2007 was installed for testing. Webpages could be opened from the bcx and 9702 controllers but not from the b4920 or webpages on a 9900. The latest Microsoft Office packages added a few accepted document extensions that allow things like word docs and spreadsheets to be opened in Internet Explorer. If the extensions are removed, the docs and xls files can still be downloaded and can be opened locally instead of through the browser. The TCP streams below show the different http request. Request with latest extensions: GET / HTTP/1.1 Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, application/xaml+xml, application/vnd.ms-xpsdocument, application/x-ms-xbap, application/x-ms-application, */* Request with default extension: GET / HTTP/1.1 Accept: */* If running the latest versions of Microsoft Office, there are a lot of extensions installed in the registry under accepted documents which creates a very long string for a HTTP request. In order to work around this, you can edit the registry. Editing of the registry should be done with extreme caution. Be sure to export a copy of your registry. Look under the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Accepted Documents Then you can export all of the keys under the above location and delete all but the default key. Once this has been done, restart your browser and you should be able to open your controller's webpages.

Issue Video Server and Video Layout not displaying in the Continuum Explorer Tree View Environment Continuum System Cause The issue is that the security key is not enabled for video. Resolution There have been a few reports of later versions of Continuum that will not display the video server or video layout class folders in the continuum explorer. If you have keys that were ordered after Continuum 1.7 the option should be enabled. For keys that have been upgraded through the Continuum versions prior to 1.7 the option may not be turned on. If the option is not selected in the key, the video class folders will not display. Some sites do not use video or are hvac sites only and have no need for this feature. The option being turned off has no effect on Continuum's performance and does not causes any issues. If you are in need of using the video server and video layout classes in versions greater than 1.7 and they are not displayed in the Continuum Explorer tree view, contact Product support for a file to enable the option.

Issue Alarms are being logged but are not being delivered to all Cyberstations Environment CyberStation, MSMQ Cause MSMQ issues Resolution When enhanced alarm delivery is selected and Cyberstations are taken offline, they will not receive alarms until Cyberstation is restarted. Occasionally you can get into a state where even though Cyberstation has been restarted you no longer receive alarms and there are a lot of messages building up in the MSMQ queues. Event Notifications Eliminate Cyberstations that no longer exist or are often offline and are setup as recipients on event notifications. These Cyberstations should be removed as recipients to avoid alarm messages from building up in the MSMQ queues. Three Reasons MSMQ does not deliver messages and some analysis tools According to MS there are several reasons why MSMQ messages do not get sent/received and in order of precedence are Connectivity, Security and Resource depletion Connectivity In Control Panel>Administrative Tools>Computer Management>Services & Applications>Message Queuing>Private Messaging>accalarmchannel, columns can be added to the queue messages line by right clicking, select View, add/remove columns Add Recipient queue and Response queue This gives you visibility into what workstations are receiving messages Ping - The amount of time that a ping test takes to respond can indicate a problem, as can the fact that such a test succeeds only intermittently. (The latter would indicate such issues as name resolution failing and the computer falling back to doing broadcasts for name resolution or network saturation). ping machinename -t this will run until stopped by pressing Ctrl-C, some baselines on each of the machines to the other machines would be good. Once a machine starts building up messages in queues, perform this ping command again to see if there's a difference. Ethereal (now Wireshark) Use Ethereal on one of the machines that is building up messages in a queue, it would be helpful to get an ethereal capture to look at the MSMQ traffic. Security A Firewall can affect MSMQ delivery. Some firewalls allow configuration down to which specific machines are allowed for the MSMQ service. Here's a Microsoft link to what ports need to be opened for MSMQ in addition to what we require for Continuum. http://support.microsoft.com/kb/183293 Resources MSMQ has a size limitation for the total amount of space used by queuing messages. If this total size has reached 1.4 Gig then more than likely the storage capacity of MSMQ has been exceeded and the MSMQ service may not start and therefore not deliver messages. Determine if the MSMQ capacity has been exceeded On each of the WS that should receive messages, go to My Computer c:\windows or c:\WINNT\system32\msmq\storage, right click on the storage folder and go to properties, note the Size. Perfmon- is a utility that can be run to take a look at resources on a machine and the MSMQ Service attribute Total Message can be added. Go to Start> Settings> Administrative Tools> Double click on Performance Keep the defaults that are listed, there should be 3 items listed for memory, Physical Disk and Processor Click on the "+" button to add a counter In the performance object drop down, select MSMQ service and under Select counters, select "Total messages in all queues" Click Add, then Click Close Right click on Total Messaging and select properties, select a color and width that will stand out, click Ok Keep an eye on the resources that are being used and adjust the machine or add resources accordingly. Logging - if it is determined that you need to log some of this info, there are some additional instructions from Microsoft on doing that at http://support.microsoft.com/kb/150934

Issue After an install of webclient 1.80/1.81 on Windows Server 2003 you receive the following error opening webpinpoint graphics: Could not find pin file at specified URL. Please contact your system administrator. Environment webpinpoint 1.80/1.81 Cause .PIN and .EMF file extensions have not been registered in the IIS MIME Types (for webClient Pinpoint graphics). Also, an IP conflict with another PC can cause this.   Resolution Webpinpoint is installed properly when first opening a graphic, you can browse to the NewGraphicsFiles folder through Internet Explorer and the web folder tab in Cyberstation pinpoint options resolves properly without Red Xs. To fix this, follow the instructions on Pg 32 in the Webclient 1.80/1.81 Installation Guide as follows Registering File Extensions for Server 2003 after IIS Installation: If you have a Windows Server 2003 system, you must also register the .PIN and .EMF file extensions in the IIS MIME Types (for webClient Pinpoint graphics).

Issue Alarm Forward and Log settings with enhanced alarm logging causes unnecessary network traffic Product Line Andover Continuum Environment Continuum Workstation Cause There has been some confusion about whether to select forwarding and logging on the recipient editor located within the eventnotification editor. Resolution In 1.5 and later versions of Continuum, a new alarm engine was introduced. To use the new alarming engine, select the enhanced alarming check box located in the database initialization editor. The enhanced alarming feature will perform both the forwarding and logging of an alarm. If the enhanced alarming feature IS SELECTED, then the forwarding and logging of a specific PC will not need to be checked ***. If enhanced alarming IS NOT SELECTED, then you will need to specify a forwarding and logging workstation. **IMPORTANT: Intrinsic alarms of type Controller Status, Fault Status and Logon Status still need their corresponding Event Enrollment object configured for logging and/or forwarding as before. If enhanced alarming, forwarding and logging are selected, there will be no duplication of alarms, but will cause unnecessary traffic on the network. If all three are selected and are on a very busy network, you may experience workstations appearing as offline. This can be intermittent depending on the amount of network traffic generated on your site. To check the settings of your enhanced alarming features, open up the database initialization editor and select either the server or stand alone button to view your settings. If your setting is not selected and you want to use the new alarming engine then select the feature. Make sure you restart ALL workstations when you change this feature. In 1.7 and later versions of continuum there is also an enhanced alarm delivery selection. This selection uses Microsoft's Messaging Queuing Service to deliver alarms. This feature allows multiple workstations to share the load of delivery of alarms to the recipients of an eventnotification. Thus reducing the work load of just one workstation to handle the delivery. The enhanced alarm delivery feature, will be best utilized when working with multiple workstations.

A cumulative hotfix is available from Microsoft that will address this issue. It can be found at https://support.microsoft.com

Issue What are the effects of points that are flagged for export on a wireless bus. Environment Continuum wireless solution Cause Information on points export over wireless bus. Resolution If there are many points configured on a wireless bus that are having their values exported it could have an adverse effect on the bus stability. The reason for this is because if a point is exported every time the value of that point changes even if it is only set for export due to an alarm it can overwhelm the wireless network. Wireless network exports are not broadcast messages like Wired Infinet, they are point to point communications similar to Bacnet exports. The way to limit this amount of traffic is to put thresholds on the points that are exported. When adding a threshold the point's value will only be sent out on the bus when the value change exceeds the threshold value. It is important to add this threshold to alarmed points if they are analog type points, because the exports will happen every value change, not just when the alarm goes active.

Issue What is the easiest way to tell if a point is being exported due to alarm attachments or programs? Environment Listview Cause Run a quick report on which points are exporting data outside of the system. Resolution The easiest method to determine what points are exported is to run a listview of points and have the column "Export" in the listview. Every point that is being exported will have a "True" in the export column.
