Issue Receive data from Trend log (Seven Trends) with incorrect base time hh:12 even though it is set to 00:00.   Environment I/NET Seven  Seven Trends Xenta Server 527 / 527-NPR / 731 Cause When using a Xenta Server as an I/NET NetPlus Router (NPR) and have configured a Trend (Seven Trends) with a sample count of 24 and sample interval of 60 minutes it appears that the time is incorrectly reported to the I/NET Host.  This issue will be rectified in a future release of the Xenta Server firmware.  Resolution As workaround to this issue, the Sample Count value below 24 should be used.   This is issue is not seen when using a Direct Connect configuration 

Issue Ordering a specific controller with the options required seems complicated. What do each of the options mean and how do I build the part number for the controller I want? Environment ACX57xx Netcontroller II Cause The parts list is huge and there does not seem to be detailed information on how to organize each character in the part number to get the controller with the options that you want. Resolution ACX Series Part Numbering Scheme ACX Series part numbering has been structured to make it easier to choose and find the right corresponding part number. All part numbers consist of 13 characters. Configurable options use unique letters so that features cannot be confused. A zero, specifically a "0", is used when a feature is not enabled in the desired configuration. To order an ACX Series controller, follow the scheme described in the PDF here to determine the appropriate part number. (Note: you MUST login to Buildings Download Center to view/download the document)   NetController II Part Numbering Scheme NetController II part numbering has been structured to make it easier to choose and find the right corresponding part number. All part numbers consist of 15 characters. Configurable options use unique letters so that features cannot be confused. A zero, specifically a "0", is used when a feature is not enabled in the desired configuration. All NetController II units are configured to support 32 IOU modules, and will come standard with Ethernet and full use of 128 MB of memory. There is no need to specify this in the part number. To order a NetController II, follow the scheme described in the PDF here to determine the appropriate part number. (Note: you MUST login to Buildings Download Center to view/download the document)

Issue Unable to use "Object" as a keyword in SmartStruxure Script program.  Environment SmartStruxure Script Object Keywords Cause The Object keyword is not supported in SmartStruxure script language because the binding structure cannot accommodate this function.

Issue Schneider Electric part number equivalent to Belimo NM24-US Environment Belimo NM24-US MD10B-24 part no 8751015000 Cause Cross reference for replacement of existing actuator. Resolution The Belimo NM24-US seems to be obsolete. The replacement today would be the MD10B-24, part no 8751015000.

Issue Using Vykon Alarm Services no sound is played on alarm popup, sound is enabled in both server and clients. Default sound is enabled and valid (operates in Windows when tested) and same for object level alarm sound. Have entered object level alarming parameters with pipe symbol, sc and tag in alarm text but even the default global sound doesn't work Environment Niagara R2 Vykon Alarm Client Cause The Vykon Alrm Client only supports wav files in standard PCM format, wav files that use compression codecs (e.g. mpeg3, etc.) do not work. Resolution Right click on the sound files and view the properties. The summary tab typically indicates the audio format. (for information on audio formats see http://en.wikipedia.org/wiki/Audio_file_format)  There are free utilities such as Moo0 Audio Converter that can be used to convert audio file formats

Issue Is there any way I can transfer a value between 2 LUA programs without using a BV or AV? Example: A Lua program (PG1) is created to turn on lighting, a variable called LightOn is created but other Lua programs PG2, PG3, PG4 cannot reference the "LightOn" variable. Is there any way a variable from one Lua program can be accessed from another Lua program? Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Lua programming Cause Each PG script has its own dedicated environment, which basically means variable names cannot be shared between scripts. The only things that can be referenced are actual objects (AV, BV, etc.) Resolution An AV or BV object will need to be created within the EcoStruxure Building Expert controller to store the value and make it available for other programs to read. For example a BV1 could be created and read from or written to by multiple Lua programs by referencing ME.BV1 For more information, please reference the EcoStruxure Building Expert Software - User Interface Guide document on the Exchange.

Issue How to measure absolute pressure in an air system? Environment SPD310, SPD360 Cause Only Differential air pressure sensors are listed in the catalogue. Resolution The SPD310 & SPD360 are the only Air Pressure transmitters we have in the Sensors Catalogue, however these should be suitable for measuring pressures most Air based systems. They can be used to measure the differential pressure across fans or dampers, but you can leave one side of the sensor open to the plant room atmospheric pressure and the other side connected in to the duct, that way it will measure the pressure in the duct relative to that days atmospheric pressure. This method will mean the air pressure coming out of the system relative to the room remains constant as atmospheric pressure changes. The SPD360 has the added local LCD display showing the differential pressure in Pascals. Note: There are air pressure switches and meters also available in the catalogue.  

Issue Badge printing was working, but when trying to print now the error is shown. The Windows user has full admin privileges Environment Continuum EpiBuilder Windows XP Windows 7 Windows Server 2003 Windows Server 2008 Cause Layouts are contained within files and the path can be specifically selected Resolution Ensure that the path to the layout is correct Ensure that the layout is the correct layout. Test with multiple layouts as it could be one particular layout that is corrupt.

Issue Explanation and detail required for Client Access License (CAL). Product Line Andover Continuum, EcoStruxure Building Operation, TAC INET Environment Windows  SQL Server Cause Information on Client Access License (CAL). Resolution Server licensing and Client Access Licenses (CALs) for the MS Server or MS SQL can become complex. It may be worthwhile to research further through Microsoft resources. SQL Server 2008 is available under three licensing models: Server plus device client access license (CAL). Requires a license for the computer running the Microsoft server product, as well as CALs for each client device. Server plus user client access license (CAL). Requires a license for the computer running the Microsoft server product, as well as CALs for each user. Processor license. Requires a single license for each CPU in the operating system environment running SQL Server. This license includes unlimited client device access. SQL Standard will normally come with 5 CALs. If more than 5 connections exist, then ore SQL CALs need to be purchased. See Microsoft Volume Licensing for more information. Note: MS Server CALs are separate and are also required. EcoStruxure Building Operation does not check CAL Client Access Licensing. EcoStruxure Building Operation Reports Server can be run using Microsoft SQL Express.
