Issue Xenta 913 is locked up randomly, and it needs reboot to make it return to work. When referring to the error log on the web page, the following errors show up: event power PowerFail 1 System is safely shutdown (Error#:49154) event power InitSYS 1 System start - power on (WARMSTART) (Error#:49156) Environment Xenta 913 BACnet Cause Possible cause is the baud rate for BACnet communication is too high that Xenta 913 can't deal with it properly. Resolution It is recommended to decrease baud rate for BACnet communication to 9600 or 19200 bps, and then Xenta 913 should work fine now.

Issue When the AS is communicating with another AS and passing values, is this done via subnet broadcast or unicast? Environment SmartStruxure AS Cause Unicast transmission is the sending of messages to a single network destination identified by a unique address. Resolution When AS to AS communication happens it will use Unicast.

Issue Configured a digital input on SXW-UI16, with nothing connected to the input used a volts meter to measure the voltage between RET and the input, the volts meter reads 20.3. Why? Environment SXW-UI16 Other modules Cause This is normal, what is being measured is the voltage across the pull up resistor on the input circuitry. Resolution Any sensor attached to the input must be able to handle the voltage.

Issue Which format will emails be transmitted in? Environment SmartStruxure Cause IT departments may need to know the format of system generated emails, especially if they use an internal mail server. Resolution The email is sent with text/plain;charset=utf-8 encoding with Transfer-Encoding: quoted-printable.

Issue When installing SQL server 2008 or SQL 2008 R2 to manually an instance for I/NET, Vista or Continuum, sometimes an error "Invoke or BeginInvoke cannot be called on a control until the window handle has been created" will show up. Environment SQL 2008 / SQL 2008 R2 Vista I/NET Continuum SmartStruxure Cause This issue is happening because of a behavior change in .NET that is exposing an issue with SQL Setup User Interface (UI). Resolution Generally, if you just rerun the installer, it won't hit the issue again. If this can't help, just manually create a C:\temp folder and it will work fine.

Issue When importing a file from TAC Menta into StruxureWare Building Operation Functional Block Editor, the import of the application file fails. Environment TAC Vista TAC Xenta StruxureWare Building Operation Cause The following characters are not allowed in object names in StruxureWare Building Operation. • / • " • ? • * • ~ • White space is not allowed in the beginning or the end of an objects name. • . (period) is not allowed in the beginning of an objects name. Colon (:) is not allowed either, but will automatically be replace by an underscore (_) when importing   In TAC Vista, signal names could contain the character "/". In SmartStruxure, this character is not allowed. Resolution Remove illegal characters from object names in the Function Block program.

Issue We want to be able to control the outputs on an I/O even if the I/O module is broken. Environment StruxureWare Building Operation I/O Modules   Cause The switches for manual override on the I/O modules needs power to be able to operate. Resolution The switches on the I/O modules that are used for manual override internally controls relays, that need to be powered to be able to operate.

Resolution Once the User Accounts were deleted and recreated with exactly the same configuration the graphics began displaying the values. 

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 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.
