Issue nvoSpaceTemp from TAC Xenta 100 series used with the room unit STR150 does not read temperatures greater than 33.4 °C (92.3 °F). Product Line TAC Vista Environment ZBuilder Xenta 121 Xenta 122 STR Sensor Cause The STR150 and the Xenta 100 line of controllers are capable of displaying temperatures greater than 33.4 °C (92.3 °F) or less than 8 °C (46.4 °F). However, the communication protocol between the STR150 and the Xenta 100 series is limited and thus restricts the temperature that the TAC Xenta 100 can read from the STR150 device. Resolution The STR150 data sheet states that temperature range transferred to a TAC Xenta 100 device is limited to 8 °C through 33.4 °C (46.4 °F to 92.3 °F). If temperatures outside of that range are needed an STR100 (simple 1.8k thermistor) or an STR-350 (communicating Lon stat with display) could be substituted. The ranges of those devices connected to a TAC Xenta 100 device are as follows: STR100: –10 °C to +50 °C (14 °F to 122 °F) STR350: 5 °C to 45 °C (41 °F to 113 °F)

Issue These LED light sequences are not found in the documentation Solid White Flashing White Alternating Blue and Amber Product Line EcoStruxure Building Operation Environment Building Operation Room Controller (RPC) 24 V Cause Not yet added to current documentation Resolution Solid white forever is either no firmware in the controller or the controller is running UBoot and not launching the firmware. Solid white, transient, and followed by yellow/amber, is UBoot running. Perform a factory reset and attempt to upgrade the firmware to the latest revision allowed based on the version of EBO used on site Flashing white would indicate a defective board requiring RMA or a power supply problem (It was seen on one site the 24Vdc power supply had been damaged and was only supplying 12 to 14Vdc. Thus replacing the power supply solved the problem) Alternating Red/Blue happens during an up rev of the firmware. It specifically happens when the EFR32 (the Bluetooth chip) is being upgraded. Generally, power supply problems can cause various issues with RPx and MPx controllers, including partial corruption of the firmware/application. A recent case had transformer secondary circuits linked that cause Red/Blue flashing and 'untranslated BACnet errors’ following a site wide power cycle. Always ensure the RPx power supplies are within tolerance and fully compliant to Grounding and Power for Systems WebHelp has been updated to include more information see RP Controller Status LED

  Issue When attempting to add a new user to the system in EcoStruxure Building Operation, a workstation crash occurs upon selecting the Create button. The crash dialogue shows: parsing "[]" - Unterminated [] set Product Line EcoStruxure Building Operation Environment Building Operation Workstation Cause The workstation crash is triggered by a misconfiguration in the password policy settings. Specifically, the Special Character field has been unintentionally deleted, resulting in it being left blank. However, the password policy still requires a minimum number of special characters to be entered (set to 1 or more). Resolution To resolve this issue, follow one of the two options below: Restore the default special characters: Access the password policy settings in the control panel. Locate the Special Character field. Click on the "Default Characters" button to add the default special characters back to the field. Disable the requirement for special characters: Access the password policy settings in the control panel. Locate the option for "Minimal number of special characters". Modify the setting to "0" (zero) to remove the requirement for special characters. By implementing either of these solutions, the workstation crash issue should be resolved when creating new users in EcoStruxure Building Operation.

Issue Deleting BACnet objects using a BACnet Operator Workstation (BOWS) can permanently remove those objects from the BACnet device.  The effected devices can be Building Operation BACnet devices, e.g. Automation Server or third party BACnet devices. Environment Building Operation Enterprise Server Building Operation Automation Server 3rd Party BACnet Controllers Cause The BACnet controller(s) in question support BACnet create and delete services on the specific objects.  Resolution Functions as Designed If the device supports create and delete services for the object it is designed to function this way. In general the BOWS should provide as much as possible a complete and accurate image of the contents of the device.  For example using the Enterprise/Automation server as a BOWS:  Creating new objects will automatically send a create-object request and attempt to create the object in the device. Deleting objects will automatically send a delete-object request and attempt to delete the object in the device. Upload and Download of object commands attempt to synchronize the database with the actual contents of the device.  Download will attempt to create any objects that are in the database (but not in the device), and also attempt to delete any objects from the device which are not in the database. Upload adds or removes objects from the BOWS database. Please see Protecting EBO/SBO BACnet objects from being deleted by 3rd party BOWS for a method of preventing BACnet points being deleted from an Enterprise/Automation Server.  Consult third party documentation to identify preventing creation/deletion.   Offline Workaround If the device supports the Device Communication Control service, and allows disable, a work around is to make changes to the database while the device is offline. For example, using the Enterprise/Automation server as a BOWS, right click the device and select Device->Communication->Disable.    Open the property grid for the device and it should take about 12 seconds before the device is reported as offline.  Any other break in communication should also work to get the device offline.  Once offline, objects can be deleted from the database without affecting the device.  But, after changing the database this way, the device's "upload" or "download" commands should not be used, as it will re-synchronize the device and database (either deleting objects from the device, or adding them back to the database).  It is important to note using this method the BOWS will not fully represent the objects in the device and also remember to re-enable the communication to the device.

Issue BACnet objects that are deleted from the BACnet side keep coming back. Product Line Andover Continuum Environment Cyberstation BACnet IP devices BACnet MSTP devices Cause Require to be able to find all the BACnet devices, delete the ones not required, and not have them reappear in Continuum Explorer. Resolution When BACnet is enabled, Cyberstation will automatically add devices into its database when it hears an “I-Am” message containing a Device Identifier it does not already know about. There is no way to disable this behavior without shutting BACnet off completely. I-Am messages are typically sent in response to Who-Is messages, but not always. Sometimes devices send I-Am messages when they start up for example.  Also, since I-Am’s are typically broadcast across the entire BACnet internetwork, the Cyberstation is likely to hear I-Am messages for lots of different reasons, like in response to Who-Is/I-Am sequences it’s not directly a part of.

Issue Is it possible to prevent a 3rd party BACnet Operator Workstation (BOWS) from deleting the BACnet objects in an Enterprise/Automation server? Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Server Building Operation Automation Server Cause Current version of EBO/SBO puts the responsibility of creating & deleting BACnet objects to the site administrator.  The enhanced security on this issue will be added in the later version. Resolution The following video demonstrates how to protect the BACnet objects in ES/AS by utilizing shortcut objects.

Issue Cannot change the IP address or host a SpaceLogic IP device, MP or RP controllers, or IP-IO modules in a second EBO Server. Product Line EcoStruxure Building Operation Environment IP address BACnet Building Operation Multi-purpose Controller Building Operation Multi-purpose VAV Building Operation Room Controller  Building Operation IP-IO Building Commission Application Cause 1. IP settings are saved (eg in Building Commission), but the IP address of the Controller does not change. (Option to change most settings is grayed out from Building Commission for hosted SpaceLogic IP devices) 2. The Controller is already hosted by an EBO server and cannot be hosted by a second EBO server, thus data objects cannot be read. 3. Rehosting an SpaceLogic IP device to a different EBO server Resolution 1. Changing the IP address "settings" can be done with Building Commission application, formely know as eCommission Tool, in some earlier versions but if the SpaceLogic IP device, formely known as SmartX IP device, is already fully hosted by an EBO Server, then a warm start from the Building Commission is inhibited. (Option to change most settings is grayed out from Building Commission for hosted SpaceLogic IP devices) Without the hosting Server initiated warm start the new IP setting will not be used. If the SpaceLogic IP device is not hosted then the IP address can be changed from the Building Commission, using the warm start option. Notes A local warm start initiated at the SpaceLogic IP device(manually with the reset button) will not force the SpaceLogic IP device to use these new settings. See BACnet/IP Controller Commissioning Scenarios The IP address of a Hosted SpaceLogic IP device cannot be modified from eCommission Tool A factory reset will force the SpaceLogic IP device to return to AutoIP and DHCP, the BACnet Id will generally be retained see Automatic Association after a Factory Reset in a BACnet Controller or IO Module 2. When a SpaceLogic IP device is fully hosted by an EBO Server, it can be BACnet hosted by a second EBO Server, but this will only contain the standard BACnet Applications folder. This hosted BACnet Device needs to be manually created using the SpaceLogic IP device instance Id.  Below, it can be seen that the fully hosted SpaceLogic IP device and the BACnet only hosting under ASP_22   3. When a SpaceLogic IP device is configured or programmed via the hosting EBO Serving using WorkStation, some of the objects (eg. Scripts or Function Block) data is not fully contained within the SpaceLogic IP device. Thus if the hosting EBO server is changed, some of the configuration data will be lost and a simple upload to the new hosting EBO Server will not upload all the data required to recreated these objects. In such a case, an export from the original hosting EBO Server should be imported into the new hosting EBO Server to ensure no data is lost.

Issue Alarms not received at the Enterprise Server Product Line EcoStruxure Building Operation, Satchwell BAS & Sigma Environment Sigma Transition Alarms Cause Alarms are being generated by the controller but do not appear at the Enterprise Server.
