Issue Users who clean-dist or factory restore JACE-8000 to Niagara version 4.1 risk losing the serial ports.   Product Line TAC IA Series Environment I/A Series N4 Jace 8000 Cause Due to an old defect (fixed in Niagara 4.2 update 2; 4.2.36.38), a programmable device that controls the serial port may be left in an erased state during firmware programming. If this happens, serial ports (COM ports) will be missing when viewing the Serial Port Service under Platform Services in a station. This continues to be an issue for customers who routinely clean-dist or factory reset to Niagara 4.1 on upgrade scenarios. It is not necessary to clean-dist or factory reset when upgrading JACE-8000. If you are advised to do so, it is recommended that you use the 4.9u1 clean dist rather than the 4.1 version one, to avoid being affected by the old defect.  Resolution When the JACE-8000 is loaded with Niagara 4.14u2 (or newer) the issue will be automatically detected and fixed on boot. However, when a serial expansion module has been erased, the software cannot distinguish between an RS-232 expansion module versus an RS-485 expansion module. The following messaging will appear in serial shell (and system logs) when the JACE is booting (it will continue booting):   Starting USB-0 and USB-1 Host controllers... Started USB-0 and USB-1 Host controllers get_ctrlperms: ctrlperms set to 644 Check for usb firmware updates Re-creating firmware info file in /etc/usb ERROR: Expansion module info file /etc/usb/350130901TF9S81 is empty, cannot reprogram or start serial ports        1) To populate the info file with path to appropriate firmware, execute one of following at console command line:               For RS-485 expansion module: echo "/sys/images/usb/vid03eb/pid2425/Tridium485-2_r01" > /etc/usb/350130901TF9S81               For RS-232 expansion module: echo "/sys/images/usb/vid03eb/pid2404/Tridium232_r01" > /etc/usb/350130901TF9S81        2) Reboot to reprogram Check for usb firmware updates done   To fix the issue, download and start PuTTY. In PuTTY Configuration, select the radio button labeled Serial under Connection type. In the text field under Serial line enter COM3 (or whatever the port number is) and enter 115200 in the text field under Speed. Press the Open button to connect. You will need the same VCP driver that is noted in Preparing for new JACE commissioning  and JACE-8000 Backup and Restore Guide. Sign in to the JACE serial shell. At the prompt type 'sh' to exit the menu and enter serial shell prompt (shell prompt is $ dollar sign). Copy the correct command from the serial shell instructions. To copy with PuTTY, click and drag over the text. When you lift the mouse button, the text will be in the clipboard. To paste the text, you simply right-click. In the instructions above, 350130901TF9S81 is serial number of a programmable device that controls the serial port. Your serial number will be different. But if that was your serial number, and the erased device was an RS-485 expansion module, then the command to enter would be:    echo "/sys/images/usb/vid03eb/pid2425/Tridium485-2_r01" > /etc/usb/350130901TF9S81   And if it was an RS-232 expansion, then the command to enter would be:    echo "/sys/images/usb/vid03eb/pid2404/Tridium232_r01" > /etc/usb/350130901TF9S81   The file name and path may change in newer versions of Niagara. Therefore, copy from the instructions given in the serial shell output (do not copy the command from this Knowledge Base Article). Press the enter key after the command has been pasted correctly. Then send shutdown to warm-boot the JACE-8000, or just cycle power.  Observe the following output on the next boot:   Starting USB-0 and USB-1 Host controllers... Started USB-0 and USB-1 Host controllers get_ctrlperms: ctrlperms set to 644 Check for usb firmware updates Reprogramming usb device: 1.2 350130901TF9S81... loaded 350130901TF9S81 with /sys/images/usb/vid03eb/pid2404/Tridium232-1_r07.bin Reprogramming usb device done: 1.2 350130901TF9S81 Expansion boards have been reprogrammed - rebooting... exiting usbinit, shutdown requested   The JACE will boot one more time, and then it will operate normally.  Please refere to this additonal article for more help.   Jace 8000 Serial Port Issues 

Issue EBO acts as a BACnet server and a BACnet client send SubscribeCOVProperty to get value updates of specific property of a BACnet object, ex. present value, but EBO respond with "NOT_COV_PROPERTY".   Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Server Building Operation Automation Server Building Operation Automation Server Premium Building Operation Automation Server Bundled Building Operation Edge Server - Standard Cause Specified property does not support COV notifications. Resolution EBO only supports SubscribeCOVProperty (DS-COVP-B) for the following properties and object types: Status_Flags: AI, AO, AV, BI, BO, BV, MI, MO, MV, Loop, Trend Log Event_State, Reliability, Out_Of_Service: AI, AO, AV, BI, BO, BV, MI, MO, MV, Loop When a client attempts to use SubscribeCOVProperty for another property not listed above, the appropriate response is 'Not COV Property', as specified in BACnet standard. When getting this response from EBO, the client is expected to automatically use another method to acquire the property value (either via COV subscription or polling). If the client is attempting to read Present_Value, then using SubscribeCOV would be the preferred mechanism.

Issue What is the b2 and i2 Controller Object Format property used for? Product Line EcoStruxure Building Operation Environment Continuum Conversion i2 Controller objects b3 controller objects Cause i2 and b3 Controller objects include a a Format field for objects created using the Continuum Conversion tool. What is this used for and how does the value effect the operation?     Resolution These Format values are propagated through the Continuum Conversion Tool for reference only and have no impact on operation in EBO. The values cannot be modified. In EBO there are two ways to configure numeric display formats. -In WorkStation property pane and watch window, the number of decimals displayed to the right of the decimal point is inherited from the WorkStation PC's regional settings. This setting applies to all values displayed in WorkStation except for values in graphics. -In graphics, the number decimals displayed to the right of the decimal point is configured value-by-value in the Graphics Editor.   The format value is not stored in an EBO export and if objects are manually created, then standard formats are used for the type of object created .

Issue Importing Security Expert controllers' serial numbers will break the import process and result in only creating default templates for the controllers. Product Line EcoStruxure Security Expert Environment Security Expert Server Security Expert Data Sync Service Cause Security Expert controllers' serial numbers are displayed in hexadecimal. However, in the SQL database they are  stored as decimal values. So the Data Sync Service is expecting a decimal integer and is instead receiving a string.  Resolution Convert the serial numbers in the .CSV import file from hexadecimal to decimal. This can be done in excel using the  "HEX2DEC" function. E.g. if the controller serial number is "ABCDEF12", it must be converted to decimal value "2882400018" before importing to Security Expert.
