Issue When is the Default Output Value applied to an IO Output? Environment AS IO Modules Cause When the AS is disconnected it does not appear to go straight to the Default value. Resolution When an IO Module becomes disconnected from its AS or the AS is unplugged, after 255 Seconds (4.25 Minutes) the IO Outputs will change from the last controlled value to the Default Output Value. When the AS is reconnected (and starts up) the outputs will revert to normal control. "Default Output Value" is an attribute of the output point and is found in the: "Properties, Configuration Settings", this is where you can define its value.

Issue When trying to select meters in Building Operation QT Administrator a 'User is not authorised to access' message appears and a log list cannot be retrieved. Environment StruxureWare Building Operation Building Operation QT Administrator Cause This is most likely caused by an incorrect trend log configuration.  Either: - One or more extended trend logs are not configured with a trend log. or - One or more trend logs are not monitoring a point. Resolution Correct the configuration and retry.

Issue If a binding variable is commended out in the program when the line is put back the binding is gone. Consider the following program... TheOUT3 binding variable is commented out... If the comment is removed and the line restored, the corresponding binding is NOT restored. Environment Workstation Script Cause Documentation Resolution This is functioning as designed, if the binding variable is removed in the program code, the associated binding is removed to avoid leaving an orphan binding. When the comment is removed and the binding variable is put back, you will need to re-bind it as SBO does not keep track of deleted bindings and can't automatically restore it.

Issue Untranslated infinity error when creating object in b3 or i2 device. Product Line EcoStruxure Building Operation Environment Building Operation Workstation Infinet i2 Controller BACnet b3 Controller Cause b3/i2 devices do not support certain characters in their objects name. Resolution b3/i2 devices do not support certain characters in their objects name. For example, creating an analog input using the name AI-1 will cause the error is the BACnet field is left blank, the EBO name AI-1 can be used but a name needs to be specified in the BACnet name field that is consistent with the b3 naming convention such as AI_1.

Issue What are the sourcing and sinking specifications of the analog voltage outputs on the different controllers? Product Line Andover Continuum, EcoStruxure Building Operation Environment i2 b3 XP IO modules Cause Sourcing and sinking refer to the ability of a DC circuit to PUSH or PULL a direct current through the circuit. Resolution Voltage Sourcing In a controller's voltage sourcing output, the output provides a voltage source that PUSHES a direct current through the load as indicated in the illustration below. The current flows from the output's positive (V/+) terminal through the load to the output's negative terminal (-/ RTN). Current Sinking In the illustration below, a controller's voltage output is sinking a current from the load. Note the voltage source in the load's circuit which is at 15 VDC. Because current always flows from positive to negative, the voltage coming from the controller's output (0 - 10 VDC) will ALWAYS be more negative than the load's source of 15VDC, thus a current will flow from the load's voltage source through the controller's output circuit to reach the negative (RTN) side of the output's circuit. The lower the voltage coming out of the controller's output the more negative it will be as compared to the load's voltage source, thus the output will be sinking the most current when it has a value of 0 volts. It is extremely important when using a controller's voltage output in a way that will make it sink current to know the maximum amount of current the output will be sinking and to ensure it does not exceed the current sinking capacity of the controller's output. The following table shows the sourcing and sinking capabilities of the voltage outputs of the different controllers. CONTROLLER VOLTAGE SOURCING CURRENT SINKING COMMENT i2/b3 814 Voltage output 0-10 V @5 ma max 1 ma max Exceeding the 1 mA sink limit will cause the IO readings to be incorrect. ie, inputs may read 999.99

Issue When importing a XIF file generated by XBuilder a warning (that might look like it's an error) is shown regarding missing file name and generated date Environment SmartStruxure Xenta Server XBuilder Cause The XIF file generated by XBuilder doesn't completely follow the LONMARK Device Interface File Reference Guide Resolution The warning can be disregarded, but the XIF file can easily be altered to avoid getting the warning if desired Open the XIF in notepad or similar editor, and change the following.

Issue Need help configuring ETR501/ETR503 setpoint feature. Product Line EcoStruxure Building Operation Environment AS IO b3 Cause The ETR50x Series sensors support a slider that can be used by the occupants to change the temperature setpoint of the controlled space. Resolution SENSOR CONNECTED TO AS IO MODULE Create a resistive input on an IO module such as the UI16 and wire the slider from the ETR50x unit to the resistive input on the IO module. Move the slider all the way to the left and take note of the value reading at the input. Move the slider all the way to the right and take note of the value reading at the input. Configure the input's conversion using the values noted from steps 2 and 3 as the bottom and top of the electrical scale (see screen shot below) Use desired setpoint values for the top and bottom of the engineering scale, in the example below the slider will allow changing the setpoint between 68 and 78, note that the units has been set to degrees F for readability. Heating/cooling application such as a PE Script can now use the value of the input as the setpoint. SENSOR CONNECTED TO b3 INPUT Same as above except that the input should be configured for VOLTAGE since the b3s do not support resistive inputs.

Issue Is it possible to change the subnet/node and domain for the Lon network in an AS? Environment StruxureWare Building Operation 1.5 and previous Cause The subnet/node for an AS is hardcoded Resolution No Subnet/node is not possible to change for an AS. But the Domain is possible to change.

Issue When opening a project in Workstation for Projects, Unkown Exception error will pop up Environment SmartStruxure 1.5 Workstation for Project PCS Cause This is a defect for SmartStruxure 1.5. When there is no Internet connection on this computer, this error will happen. Resolution This issue will be fixed in SmartStruxure 1.6. Currently the workaround is to obtain the Internet connection for this computer, at least when opening the project. It should be OK to remove the Internet connection after the project is opened.

Issue In the past there was no way to calibrate the space temperature from a STR-150 when used with a Xenta 121 FC/HP.  Environment STR-150 Xenta 104A Xenta 120 Xenta Programmables Cause Any calibration applied to the temperature of a STR-150 had to be done downstream of the stat in the controller. In the past when the STR-150 room stat was wired up to a Xenta 121 there was no way to calibrate the space temperature as the Xenta 121 FC/HP had no kind of Temp Offset in the controller. Resolution Starting with version 1.4 (released September 2013) of the STR-150, there is a calibration feature built into the stat. This feature allows the calibration to be applied before the temperature is sent down to the controller (Example: Xenta 121 controller). Below you can find out how to check the version number of the stat and how to perform the calibration. There is not a way to upgrade older versions of the STR-150 to 1.4 or greater. Checking the STR-150 version number The version number of the stat can be found as parameter P0. View version: Push the fan and bypass button simultaneously for 2 seconds to display P0. The version number will be displayed here. Using the STR-150 Calibration Feature Enter Configuration: Push the fan and bypass button simultaneously for 2 seconds to enter P0.   In P0, hold down the bypass button and push the fan button three times to enter configuration mode. Note: the wrench symbol is lit when the STR-150 is in configuration mode.   In Configuration Mode: Press the fan button repeatedly until you reach parameter F0. Note: The two digits farthest to the left on the display show the parameter, while the two digits farthest to the right show the value.   Use the increase or decrease button to adjust the value. The offset scale ranges from 0-99 which corresponds to -5.0 to +4.9 degrees. If the STR-150 is setup for degrees C, then the offset is exact. If the STR-150 is setup for degrees F, then the offset is recalculated to a corresponding value.   Exit Configuration Mode: Push the fan and bypass button simultaneously for 2 seconds or allow the idle timeout to exit configuration mode on its own.

Issue When adding MNL controller in Workstation for Projects, it will show up an error: Object type is not supported. Environment SmartStruxure 1.5 Workstation for Project PCS MNL controller Cause When using the Project Configuration Server, you cannot create MNL LonWorks devices and applications. Accordingly, the WorkPlace Tech Editor option does not display in the Control Panel. Resolution MNL LonWorks devices can be added in an Enterprise Server or Automation Server after deploying a project to one of these servers.

Issue When deploying ES/AS, it will go through for a while until the end. Then it will show failed, and the cause is communication error. Environment SmartStruxure PCS Cause 1. First check whether there is any real network issue, like router setting, fireware or anti-virus software. If it is confirmed that the network is good, check whether the date/time setting match the current ones. 2. If both are checked for the first point, the cause is there is a defect for PCS when the project contains BACNet interface and objects. Resolution 1. Change the date/time to current ones. 2. If it doesn't work, contact PSS to ask for hotfix: R1.5.0.7201.

Issue Need to downgrade AS from 1.5 to 1.4,  quick press "reset" 3 time, AS geso to DFU mode, after select "new database", get an error "New database failed" Product Line EcoStruxure Building Operation Environment Automation Server AS Device Administrator SBO 1.4 1.5 Cause AS and PC connected with USB and Network cable USB port on laptop (leveno) has additional power on one of the USB ports, switch to different port Firewall was enabled and disabled firewall Resolution Disconnect Network cable, use USB connection only (May need to select a different port on laptop, see Cause Notes above) Quickly press "reset" 3 time to DFU mode Click "Update Device" Icon and select "New database" If the above fails, try another USB port and disable antivirus software. In some cases, you will need to: Place the device in DFU mode Power down the AS Let it sit for at least an hour to let the capacitors lose their charge.   Power up the device again, place it in DFU mode Use the USB connection to load the correct version

Issue A large number of "A Log Data Transfer Has been Missed" events are being reported by the AS. All events are associated with b3 points that have intrinsic logging configured (where log configuration is part of the point properties configuration) and a StruxureWare Building Operation Extended Trend Log is attached to the point. Product Line EcoStruxure Building Operation Environment b3 Log Data Transfer Extended Trend Logs Cause We have seen these events reported when the number of log records configured in the b3 point is not evenly divisible by the Maximum Log Transfer Interval in the Extended Trend Log object. When the Extended Trend Log retrieves data from the objects intrinsic log in the b3 controller, it grabs this data in batches or portions. The size of these portions is defined by the Maximum Transfer Interval in the Extended Trend Log configuration. For example, where a b3's intrinsic log is set to 1 hour Log Interval and the Log Records is set to 72 (three days), if its associated Extended Trend Log has a Maximum Transfer Interval of 1 Day, the it will grab the first 24 records during the first pass, the next 24 records during the second pass and the remaining 24 records during the last pass. If the number of Log Records defined in the point configured is 80 instead of 72, the same Extended Trend Log will grab the remaining data in a fourth pass. However, if the amount of data remaining to be grabbed does not represent a span of time equal to the Maximum Transfer Interval, the Extended Trend Log will not grab a full period of data. In some cases when this happens data from this fourth pass can be lost and this will be reported as an "A Log Data Transfer Has been Missed: event. Example: Using our example above, and an intrinsic log Record Count of 80, the Extended Trend Log will grab the first 24 records during the first pass, the next 24 records during the second pass, the next 24 records during the third pass. It will then grab the last eight log records in a fourth and last pass. It is during the transfer of this last smaller group of data where there may be a failure of the data transfer. Resolution The number of Log Records configured in the points intrinsic log times the Log Interval should equal a period of time that is evenly divisible by the Maximum Transfer Interval time period. For example, if the Extended Trend Log is configured for a Maximum Transfer Interval of 24 hours, and the b3 point is configured for a 15 minute Log Interval, the Log Records can be set to either... Log Records = 96 (4 samples per hour X 24 hours -- a full days worth of data) Log Records = 192 (4 samples per hour X 48 hours -- two full days worth of data) Log Records = 288 (4 samples per hour X 72 hours -- three full days worth of data) and so forth.
