Issue The ACX57xx controller datasheet does not specify the AC power voltage range/ tolerance. Environment ACX ACX5740 ACX5720 Cause The DC power input specifies the voltage range on the datasheet. No documents specify the AC voltage range. Resolution You can power the ACX57xx controllers from either AC or DC power. The DC range is 12VDC - 28VDC. Max' power consumption = 50W. The AC voltage is 24VAC +10% -15% 50/60Hz. Max' power consumption = 90VA Giving an AC voltage range of  20.4VAC - 26.4VAC.

Issue Graphic pipes are missing from Px pages when viewed via a Web Browser, however pipes are displayed when viewed via WorkBench. Environment Niagara G3, ENC-520 Cause The needed kitPxHvac module was missing from the ENC-520. It seems the kitPxHvac module was not installed to the ENC. Usually all required modules are automatically installed to the ENC at the time of a station install, but for some reason the kitPxHvac module was not installed. Resolution Manually install the kitPxHvac module to the ENC - Open the Application Director window for the ENC hosting the graphics - Double-click on Software Manager - Select the kitPxHvac module from list and click the “Install” button at the bottom of the screen. - Click the “Commit” button to install the kitPxHvac module to the ENC A reboot of the ENC should not be required. Open a new Windows Browser and browse to the ENC. The pipes should now display correctly in the graphics.

Issue Automation Server stuck in Reboot Cycle Environment Automation Server Cause This experience is not typical so below is a list of solutions that have worked in the past. Resolution ES - AS Communication Issue - This fix works when the boot cycle only occurs while the ES is online. You can prove this is the case by stopping the Enterprise Server through software administrator, then attempting to log into the AS Log into the Enterprise Server Click on the Root Server Object in the System Tree Pane Click on the Communications tab Verify that the listed IP address for the Enterprise Server matches the IP address of the machine In the System Tree Pane, expand the Servers folder Delete the Affected Automation Server. NOTE: This will break all binds to/from this server. Log out of the Enterprise Server and Log into the Automation Server to verify that it is stable. Log out of the Automation Server and back into the Enterprise Server Re-add the Automation Server to the Enterprise Server

Issue Schneider Electric MTN881001 or the SVEA LON I/O Module DR-N 3DIM 1-10V. Changing the SNVT nviLALampValue_? does not give the expected output. Environment MTN881001 SVEA 36237-552 Cause Changing the SNVT nviLALampValue[i] to the following values, shows the following VDC volt on the analog output: nviLALampValue Analog output 100.0 1 -  9,94 VDC 80.0 1 -  7.65 VDC 60.0 1 -  6,75 VDC 50.0 1 -  6.25 VDC 20.0 1 -  4.86 VDC 1.0 1 -  3.97 VDC When nviLALampValue is 50.0 1, the analog output is 6.25 VDC (not proportional) and the minimum analog output value is 3.97 VDC, which does not make sense.   Resolution The module is using a logarithmic behaviour for the 1-10V output as default. This is because the device is mostly used for fluorescent lamps. You can change the behaviour by using the UCPTadaptationTable in the lamp Actuator object. UCPTadaptationTable consists of 21 values representing the digits (from 0 to 255) for the output value in steps of 5%. This means:   first value: 0% second value: 5% third value: 10% ... 21st value: 100% To get a linear behaviour you should set as follows: first value: 0 second value: 13 third value: 26 ... 21st value: 255

Issue After upgrading a TAC Vista system on a site with high IT security you can end up with a wrong schema version in the SQL database causing issues such as failure to insert trend log data. Environment TAC Vista SQL Cause In some versions of TAC Vista, the SQL database upgrade carried out during the installation of TAC Vista doesn't upgrade the SQL database to the newest version. The first time you start TAC Vista Server, the server (TACOS) carries out the remaining upgrade steps. On a site with very high security standards, TAC Vista Server is however not able to apply the last SQL database upgrade scripts as those can only be carried out by the IT department directly on the SQL server, and as a result the SQL database is not fully upgraded. Resolution   1.      Note exactly what schema version the SQL database currently has This can be checked through SQL management studio with this query USE taclogdata; SELECT dbo.DSS_SchemaVersion() AS Db_SchemaVersion 2.      Note exactly what version of TAC Vista you have upgraded to 3.      Contact PSS to get a SQL upgrade script specific for the site and run that on the SQL database

Issue How to change the Standby image on a SE8000 controller to something other than standard factory image Product Line EcoStruxure Building Expert, Field Devices Environment SE8xxx range Cause The standard standby image for the SE8300 does not meet the customer requirements Resolution See the link below to the Exchange for the software and instructions on how to perform this process. Reference page 4 of the Uploader Tool - SE8000 Series Room Controllers.

Issue Reportserver does not delete the trend data when an extended trendlog is deleted in StruxureWare Building Operation. Environment StruxureWare Building Operation Webreport SQL Cause When an extended trendlog is deleted in StruxureWare Building Operation, its corresponding data in webreport server are not deleted. This means that when you want to look at a trend in the reportserver you will still see the deleted trendlog. No new data are collected but the previously collected data will be there. Resolution This is by design. The historical data are not deleted from SQL; however,  a side effect of this is that the webreport interface will still show the extended trendlog after it has been deleted in Workstation.

Issue Does the LCM driver support tunneling? Product Line TAC IA Series Environment R2 UNC with LCM driver Cause Tunneling is needed to make programming changes to the LCM's. Resolution It is possible to tunnel through the UNC to the LCM's, but it requires an RS-232 connection from the UNC to one of the LCM's.  See the LCM Integration Guide F-27422-2 for details.

Issue Need to use a controller that has no BACnet functionality due to network security limitations on site. Environment Continuum bCX1-CR-INF (bCX9640) Cause A customer has a site with restrictive network security requirements and BACnet devices (or any other open protocol) are not allowed. Resolution The bCX9640 is an Infinet protocol controller only. This version of the bCX firmware does not have the BACnet stack installed, and there are no BACnet points able to be created in this controller. You will be fine to use this controller where BACnet support is not required or allowed.

Issue One of the following errors is thrown by the Hasp Key Utility when attempting to update the Continuum License key using the V2C file received from Schneider Electric. Invalid Parameter Update failed: KeyIdNotFound Product Line Andover Continuum Environment Continuum 2.0 Hasp Key Utility License Cause The V2C file that was emailed to the customer is corrupted. When Web based email is used to receive the v2c file from Schneider there have been cases where the file is not received in its original form.  When this happens the file size of the attachment appears to be correct.  When the c2v file is save to a folder on the workstation PC however, the file size reported is 0kb.  Resolution The solution to this is to use a non-web-based email application like Outlook or Outlook Express. 

Issue Troubleshooting 4417 DEVICE_ERR_NOADDR_I2C errors seen in Controller's Error Log.

Issue Do not get any values in webstation Bindings in TGML do not work Environment Vista Cyrillic Cause If bindings in TGML contain Cyrillic characters and the operating system installed is set to a language that can not handle Cyrillic (i.e English), the bindings will not show their values. Resolution Set the region and language settings all to the desired language, i.e Russian or Polish. Be sure Webstation is set to handle the language by installing the correct language pack. Edit the TGML and make a small change so you can save again, this time the Cyrillic letters will be understood by Tacos.

Issue Unable to Import/Export objects from/to a Multi Purpose Manager (MPM) Environment SmartStruxure Lite Multi-Purpose Manager Cause The “save to file” button cannot be activated after clicking on “prepare data”.     Resolution The browser being used needs to have Adobe Flash Player plug-in installed. Check if flash player is installed on your computer using the link below. The latest version of Flash Player can also be downloaded from the same page. http://helpx.adobe.com/flash-player.html

Issue How can the size of a program (Lua Script) be seen? Product Line EcoStruxure Building Expert Environment Site with MPM Cause What size is the program? Resolution The size of the script is the size of the exported as a txt file. For a graphical script, convert the graphical script to text format (ignore warning but do not save script otherwise you will lose the ability to edit your graphical script) then save it as txt file. Lua Program Information The CFG1 object of any given Manager can provide detailed information on the average execution time of all the Lua processes in the system (in milliseconds), along with their memory usage and available memory (in bytes). The "Max Size" will never change, since 16MB are always reserved for the Lua tasks. But the "Size Used" is a good indicator of how much memory is currently being used by the Lua tasks. Note that approximately 8MB are used by default. So anything above 8MB will represent the custom Lua programs current memory usage. The "Avg. Execution Time" is the most interesting value. It represents how many milliseconds it took for all Lua programs to complete. When the system is empty (no scripts, no trend logs, nothing) the value should be below 100ms. An average load would be around 500ms and an overloaded system will take above a second (1000ms) to complete all of its tasks.
