Issue Most recent access events do not appear in door's events tab. Environment CyberStation CX9680 ACX5740/20 CX9702 CX9900 ACX7xx Cause Events recorded with invalid time stamp in the future (i.e year 2089). At some point and for unknown reasons the controller was using a time stamp with the year set to 2089, these events show up first in the door events tab and fill it up. Resolution From a list view of access events delete all events that have a time stamp in the future.

Issue The LoopSingle block in LON and BACnet controllers contains an input called OutputReference.  Is this input intended to be used only if Integral (iGain) is not used or can they be used simultaneously? Environment MNL LON Controllers MNB BACnet controllers Application programming created using any controller compatible version of the WorkPlace Tech Tool software. Cause In the Loop Single block, is the Output Reference only used if the Integral is not used or could/should they be used simultaneously?   Resolution The "Output Reference" sets the balance point for the loop, i.e., the loop output when the input matches the setpoint. The Output Reference function operates with or without integral. If Integral is being used, its calculation can and will shift the output in the same manner as if the Output Reference were specified to be zero. The Output Reference is usually set to an initial value that is expected to cause the loop to balance, for example, 50%. The loop is then tuned by widening the TR and using Integral and if needed Derivative. Once stability is achieved, the Output Reference is adjusted to match the output of the loop.  

Issue Notification Class 150 (or any Notification Class) alarms cannot be found in EVENT.EVENTHISTORY Environment I/A Series R2 Cause Notification Class 150 was not added to the Enterprise Server station and UNC station's NotificationService containers. As such, objects configured for alarming at notification class 150 will not have its alarms archived to Enterprise Server. Resolution Add a new Notification Class to the UNC station's NotificationService container. In the Notification Class properties, go to the Config tab and set the notificationClass to 150*. Copy this Notification Class and paste it into the Enterprise Server station's NotificationService container. Configure the notificationClass to 150* (the notificationClass setting does not remain when you copy and paste the Notification Class object). * This resolution does not apply just to Notification Class number 150. It applies to any Notification Class with a similar problem.

Exit Continuum Run Continuum analyzer report Start Continuum, you will find "BACnet  Devices" folder comes in again Right click Root and select " Find New BACnet Device" When you see BCX1 comes in again, select it and do "send to database" Open BCX1 from the BACnet side and no error prompted.

Issue Editing objects on a remote Sigma client takes about 10 seconds to open editing window. Environment Sigma Editing Object Edit Remote client Cause PC / Laptop specification was not to the recommended minimum. Resolution The reported issue was that when an object was edited, the editing windows could take at leased 10 seconds to open. The minimum specification is as follows; As previous recommendations, the highest PC specification should always be sought. However, the minimum system requirements for a Sigma Server or Sigma Standard Client are: PC with 2.0GHz processor (minimum). Mouse and keyboard. CD-ROM drive (CD-Writer recommended). 2GB of RAM. Hard disk with a minimum of 16GB of free space. 128MB SVGA graphics card. Monitor - 1024x768 17". Ethernet Network interface card with 100base T connector (RJ45). (100Mbits/s) Parallel Printer Port (Centronics) or USB port for Printer whichever is appropriate 1 spare USB port for Dongle (Server only). Operating System – please see below  Note: This is the minimum specification for a typical Sigma server of 10 controllers or fewer. As the number of controllers/objects increases, so should the PC specification. A large system should typically have a Pentium3.2GHz quad core processor, 3 to 4GB of RAM and a high speed HDD (SATA II, 7200 rpm + min 16MB cache).  Note: As Sigma operates on a 32-bit operating system no benefit will be gained by having a PC with more than 4GB memory.  Where a lower specification PC is currently being used, this release of software can be run. However, the performance would not be that of the recommended PC specification.

Issue Continuum LAN controller going offline and logging error 0x00006c0f and 0x00006c10. Environment CX9900 CX9640 CX9702 CX9680 ACX5720 ACX5740 Cause The errors 0x00006c0f and 0x00006c10 are typically logged as a pair and indicate the controller has detected an issue with the physical layer of the network. The errors come from the PHY chip in the controller's network interface adapter. The Controller Error Log Tool gives the following text for the error codes: 34 W 12/12/2011 08:57:47.00  0x00006c0f 0x00002600 0x01901848 0x0000c540 0x00000000                                         buffer passed in was too small (LAN_ERR_BUFFER_TOO_SMALL_ERROR) 35 W 12/12/2011 08:57:47.00  0x00006c10 0x00002600 0x019018b0 0x0000c500 0x00000000                                         buffer passed in was invalid for free (LAN_ERR_ALLOCATION_ERROR) Resolution Make sure the ethernet cable is properly inserted at both ends, the ethernet cable may have to be replaced. Determine whether the problem is in the switch/router, move the controller to a different port on the switch/router. Switches/ports have many different ways to be configured and can affect the controllers connection status. If move to a different switch or hub corrects the issue, analyze the configuration of the ports. Although not a common failure, the issue could be in the controller's hardware, the controller may need to be replaced.

(HTTP port=80) [/WoodMode Environment Niagara R2, WorkPlace Pro Version 514 Cause The Echelon USB Lon adaptor was first supported in Niagara R2 build 522. Resolution Niagara version 514 does not support a Lon USB adapter. If possible, upgrade to Niagara version 522 or later. In cases where upgrading is not an option and an USB adapter must be used, then the following should be applied. Stop the Enterprise Server station. Open Windows Explorer and browse to niagara.r2.301.514/nre/bin folder. Find the lon.dll file and rename it lon.dll.old. Copy the lon.dll from a later Niagara Build, i.e. 522 or later. Paste copied lon.dll to Niagara.r2.301.514/nre/bin folder. Restart the station. The Lon Service should now start and Lon communication should be established.

Issue Unable to open I/A Series R2 Workplace Pro or the R2 Admin Tool on a specific computer.  No error window popups are seen.  When you attempt to open the program, it flashes its opening screen briefly then dies. Environment I/A Series R2 WorkPlace Pro I/A Series R2 Admin tool Cause Insufficient computer memory to allow standard 1024mb to be reserved for the Java heap. Resolution To resolve this issue, you can adjust the Java heap settings in the nre.properties file. It is important that you only make the changes as detailed below. Make a backup copy of this file before proceeding. Locate the file nre.properties in \niagara\ \nre\lib Open the nre.properties file using a text editor program (Notepad).

Issue I need an object in the UNC that works like the Select object in WorkPlace Tech. Environment I/A Series R2 (Niagara) UNC Cause Specified logic requirements for the UNC station require it. Resolution Inside the TridiumX container - programlib jar - hvac container there is an object called AiMapping that will perform a select function similar to that of the object provided with WorkPlace Tech.

Issue One of the critical properties of an object using COV notification is the covIncrement value.  If the device objects are learned as "lite" objects the covIncrement property cannot be viewed or changed at the UNC. Environment I/A Series R2 (Niagara)  Cause BACnet "lite" objects by design do not have the covIncrement property.  If COV notification is used with lite objects and it becomes necessary to increase the covIncrement property for an object you would have to go to the controller with WorkPlace Tech change the covIncrement of the point, compile and download the application and then test to see if the new covIncrement was sufficient. Resolution When learning objects in the BACnet service - BACnet Utilities on the "LearnDevice" window uncheck the box next to "Use lite objects". With full BACnet objects the  covIncrement property can be viewed and changed from the UNC.
