Issue Station down station up alarms are constantly generated even though the Enterprise Server and UNCs are not actually down. A station up alarm for the same station was generated within a short period of time (seconds).  Environment I/A Series R2 Enterprise Server and Universal Network Controllers Cause A station down alarm will be generated if the station does not respond within the timeout configured for the station.  Resolution In a station's AddressBook, the entry for a station has a 'Monitor' checkbox. A station down alarm is generated if the station does not respond within the timeout configured for the station in the AddressBook entry. The timeout by default is 1 minute. This can be increased if false station down alarms are being generated. You can also disable the station monitor if required. 

Issue The telemetry input can be used to control the lamp and dim function from an external source. Environment WLEDL-150 Cause Remote Operation. Resolution By default, the telemetry inputs are wired together (CLOSED) for standard photocell controlled on/off operation. If required to be activated by an external source, connect as an appropriate volt-free or TTL input source using a dry contact. Volt free input/dry contact: TTL input Non polarity sensitive: Orange = TTL +, Purple = TTL (GND) 0V = Light on, 3V = Light off Short circuit = light on

Issue Unable to save a Function Block or Menta program that contains a module named "IO" in StruxureWare Building Operation 1.4.1 Environment Function Block program Menta program SmartStruxure 1.4.1 Cause A bug prevents using "IO" as a module name in Building Operation 1.4.1 Resolution Changing the module name will allow you to save.

Issue After installing the Niagara AX Lon Tunnel Client, the service fails to start and Windows displays the following error: Could not start the NiagaraAX Serial Tunnel service on Local Computer. Error 1068: The dependency service or group failed to start. Environment I/A Series AX Lon Tunnel Client Cause There are two possible causes of this issue. The LON port specified is already in use and assigned to a physical LON adapter.  The LON adapter assigned to this port may not necessarily be currently installed into the computer. One of the underlying Windows functions or services required by the AX Lon Tunnel is not installed or is corrupted. Resolution To verify that the LON port you have selected is not already installed in the computer, perform the following steps: Open the "LonWorks Interfaces" applet from the Windows Control Panel (Procedure describes operation with OpenLDV 4.00 installed.  The procedure for OpenLDV 3.20 or OpenLDV 3.40 is similar to what is shown in the following steps. Under the "View" menu, insure that "Show detached interfaces" is checked. Select a LON port that is not already shown in the list and enter it in the "Lon Port" field of the "Niagara AX Lon Tunneling" Windows control panel applet. If the LON port name is valid and the NiagaraAX Lon Tunnel service still displays the 1068 error message, an issue could be occurring with another Windows service or DLL file.  Microsoft provides a method of diagnosing and possibly correcting this type of issue. Open the Windows Start Menu and in the "Search Programs and files" box enter the command:       cmd In the Command Prompt window, type in the following command:       sfc /SCANNOW This command "scans integrity of all protected system files and repairs files with problems when possible". In the event that this process finds an uncorrectable issue, the program will stop, displaying an appropriate diagnostic message.

Issue All the alarms from an OPC Alarm & Events (AE) server are coming in as priority 5. Is it possible to change this? Product Line TAC Vista Environment Vista OPC Alarm Events (AE) client 3rd Party OPC AE server Cause The alarm categories/priorities for alarms that come from an OPC AE server are set on the OPC server. Some OPC AE server offer limited configuration possibilities and it may be desirable to change the category/priority in Vista. Resolution The priority can be changed by: Select the OPC AE server object in TAC Vista Workstation Open the Properties dialogue Locate the alarm settings section and the alarm category mapping will be displayed. By default "Use alarm priority map" is selected. In the example below, all the alarms from the OPC AE server with a category of between 500 and 599 will be mapped to category 5 in Vista. This mapping can be changed as desired.

Issue After a power cycle the Xenta Server need to be re commissioned to get it SNVTs functioning and the controller back online in NL220 or LonMaker Environment Lonmaker, NL220 Xbuilder 5.1.6. Cause As the Xenta Server is used in LonMaker and Vista the subnet is set in the Xenta project. When you then commission in NL220 or LonMaker the address is then set to the LonMaker or NL220 database specification. On a power failure the Xenta server reverts to its Xbuilders Subnet node address and goes offline in LonMaker or NL220 Resolution Save the X-Builder project out of the Vista database. this will allow the Subnet node to be set under the LON heading in the X-Builder project. Match the subnet and node address to the LonMaker or NL220 database subnet and node address of the Xenta Server. Save the X-Builder project back into Vista and then download to the Xenta Server. Now on a power cycle the subnet and node will Match the LonMaker or NL220 database and remain online.
