Issue After copying sections of logic from one application to another the pointers from that logic won't connect to other objects and therefore show up as red lines. Environment WorkPlace Tech Cause Copying sections of logic from an older application has been known to cause this. Resolution To recover the application remove all objects and reference tags that exhibit the connection issue, compile the application and then re-create the deleted logic by pulling objects from the Shapes window.

Issue How do you convert MicroNet 2000 controller filenames generated by the MicroNet Controller Interface "Get Multiple" function to integrator and controller addresses? Environment MN-2000, MN-CI, MicroNet Controller Interface Cause The "Get Multiple" function is used to upload application programs from multiple MicroNet controllers under one MicroNet Integrator or a series of MicroNet Integrators.  The application programs are stored as files with the integrator and controller addresses appended to the name. Resolution When uploading files from multiple MicroNet VAV Controllers, the CI creates unique filenames for each uploaded application file by appending the integrator number and device number to the prefix entered in the Enter File Prefix window. The integrator number and device number are appended in hex format. The file shown in the illustration above was uploaded from MicroNet controller 11 under MicroNet integrator 6.

Issue WebStation connection is unreliable when using a 4G (cellular) connection Auto logoff times are not obeyed  Product Line EcoStruxure Building Operation Environment Building Operation WebStation 3.x Broadband Cellular Networks Cause WebStation creates a subscription with the Building Operation server, so it will attempt to connect every 10 seconds.  If this connection is removed/interrupted/ or no longer required for a period of 60 seconds, WebStation will force itself to log out.  This setting is currently fixed and cannot be adjusted.    Currently, there have been instances where this connectivity issue is seen when using, as shown below, a device with a broadband cellular connection attempting to connect to a Building Operation server that also connected to the same/similar cellular network this is the most common scenario where this issue is seen. Resolution It is recommended not to use these cellular network connections to permanently display Building Operation Server information, especially from mobile devices connecting to the cellular network.  This type of connection should be used sparingly and for quick access to view/check information as necessary.  Connection loss can be expected if you move away from the webpage for more than 60 seconds.  Any lengthy connections to the Building Operation Server are recommended to use a more permanent network connection.     Issues have not been seen when using broadband Internet or a similar connection as shown below to a remote cellular Building Operation Server.  This meaning that the EcoStruxure Building Operation system has remote Internet access via a broadband cellular connection. To troubleshoot this further, capture a HAR file using the details provided here How to collect a network trace | Microsoft Docs and reproduce the issue while this debugging window is open within your browser.  Note: This capture must be done at the source; that is where WebStation is running.  This may not be easy to do using a mobile device.   Send this saved HAR file and the Internet browser version and EBO version used along with connection types to your local support channel. 

Issue There is a problem after upgrading the SystemDB to N4.10. Product Line TAC IA Series Environment I/A Jace 8000 N4.10 I/A Enterprise Server N4.10 Cause In Niagara 4.10, we upgraded SystemDB from Orient v2 to v3, and as a result of that change, any customers that are utilizing SystemDB on their Supervisor stations will need to re-index accordingly upon upgrading to 4.10. Resolution In Niagara 4.10, the SystemDB has been upgraded from Orient v2 to v3.  Because of this change, customers that are utilizing SystemDB on their Supervisor stations will need to re-index upon upgrade to 4.10.  Please note, re-indexing can take a considerable time upon upgrade, and the DB will not have accurate information when queried until the index upgrade is complete. After upgrading to 4.10, invoke the actions that force system indexing.  Be aware that re-indexing can take some time, and that the DB won’t have accurate information when queried until the index is complete. The following image shows how to invoke execute on the Local System Indexer: If the Station has a DB configured to contain information about points on other stations, the Niagara Network System Indexer should be used, rather than the Local System Indexer.  Additional details regarding indexer actions can be found in the Niagara System Database and System Indexing Guide.

Issue Adding Web.Client to an existing site that has Continuum installed with the CFR compliance option. Environment Continuum with CFR Compliance Cause Can't find any part numbers for Web.Client with CFR compliance or an option to add it. Resolution We do not have an option for Web.Client with CFR. One of the requirements for CFR is the inclusion of operator text when performing certain actions; there is no way to prompt for, or supply, this operator text when using a Web.Client browser client.

Issue All Custom Types in an AS-P suddenly disappeared and it is not possible to create any new Custom Types. When trying to create a Custom Type it results in an invalid Custom Type object:   Product Line EcoStruxure Building Operation Environment Building Operation Automation Server Premium Cause For an unknown reason, the Configuration database has become corrupt. Resolution Workaround 1: Do an upgrade of the AS-P to the same version which should fix this issue.   Workaround 2: Restore a backup taken before this issue appeared.

Issue Require a relay contact to close when an intercom call is being made. The relay is then wired to an information display with displays to alert personnel of the incoming call.  Product Line EcoStruxure Security Expert Environment Security Expert SX-IPI, SX-IPI-C Cause Require visual notification of incoming calls viewable by operators not currently at the monitoring desk. Resolution In the SP-IPI-C configuration settings, there are a number of options in the "Call State Trigger" setting that can be used to trigger the onboard output during certain conditions. One of these is when the intercom is making a call.  Under Security Settings, there is an option titled Alert Trigger Setting where the call state can trigger the output. Alert Trigger SettingCall State Trigger: enables the output to be triggered by the call state of the Intercom. The output triggers when the call state matches the selected state.   Enable the Call State Trigger and set the value to Calling or Ringing depending on if the SX-IPI-C is making or receiving the call. Call State Trigger Wire the output relay into the SX-IPI-C input. Register the input with Security Expert. See details starting at the Adding the Expander Setup in the Security Expert system section in the SX-IPI-C IP Intercom with Camera Installation Manual. In Security Expert, configure the input to trigger an alarm which in turn will trigger an output. Create an Event Filter and add the following event type to it. Input <ZONE_NAME> Opened Create an Alarm add the Event Filter to it. Create an Area If you want a common output that triggers when any object alarms in that area then set the Alarm Output fields on the Outputs tab. If instead, you want the output tied to the Input Type or individual Inputs then go to the next step. In your Input on the Areas and Input Types tab add your Area to Area 1 field and set the Input Type 1 to Instant. In the options enable Log to Event Buffer so we can see the activations. If a common output for all inputs of the Input Type then; On the Options (2) tab enable the Activate Control Output On Alarm and Deactivate Control Output On Restore options. On the Configuration tab set the Control Output to the output you want to trigger. Else if each input has a separate output then; On the Options (3) tab enable the Activate Input Control Output On Alarm and Deactivate Input Control Output On Restore. In each Input set the Control Output to the output you want to trigger.    

Issue For integration purposes, it is important to clarify exactly what Andover Continuum X-Driver protocols have a prescribed upgrade path and remain supported in EcoStruxure Building Operation (EBO) Product Line Andover Continuum, EcoStruxure Building Operation Environment Andover Continuum Building Operation Enterprise Server Building Operation Automation Server Premium Cause As more and more systems Transition from Andover Continuum to EBO, customers need to know how existing Continuum X-Drivers can be supported and upgraded to maintain data connectivity in their new EcoStruxure Building Operation architecture.

Issue A MN-Sx sensor is installed more than 200 feet away (the maximum specified) from a MNL controller. The dynamic temperature value drops in and out at the controller.  Is there a repeater that can be installed to improve communications? Environment MNL MN-Sx Cause Cable run extends beyond the specified 200 feet. Resolution There is no repeater available that can be used for the MN-Sx cable run.

Issue ACX781's are still installed on some older sites but the cabinet keys cannot be found. Can these be replaced? Environment ACX781 Cabinet Enclosure Cause No one has the cabinet key and it needs to be replaced. Resolution The ACX781 controller has been discontinued since 2007. The stock on the cabinet lock/key assembly has been depleted since then and there are no replacements available.

Issue Is it possible to include the Comments field from Extended Logs into Report Server Reports? Product Line EcoStruxure Building Operation Environment Building Operation Reports Server Cause Regardless of the new Reporting Features in EcoStruxure Building operation (EBO) 3.2, users of existing systems up to and including EBO 3.1 are asking if it is possible to include the Comments field in Extended Logs within the Enterprise Sever to enhance the data in RS Reports? Resolution Extended Log Comments within the ES are not available to Report Server reports today and given the move to new Reporting Features now available in EBO 3.2 it is unlikely that an Enhancement Request for such a feature would be implemented quickly. Therefore, the suggestion here would be to migrate the Extended Logs to External Storage via TimeScaleDB where all the Extended Log data (including the comments) can be freely manipulated by 3rd party Reporting Products.

Issue Implementing a pre-entry access card anti-passback using Plain English program Product Line Andover Continuum Environment Continuum Net Controller II Continuum ACX 2 Controller Continuum ACX 4 Controller Cause The anti-passback implementation in Continuum engages when the credential holder enters the area as detected by the door switch/contact. (if no door switch is configured, then the credential holder is considered to have entered the area immediately after access has been granted by the system) When doors are located in close proximity to each other, as is the case with a bank of turnstiles, for example, the built-in anti-passback scheme is easily defeated as a cardholder is able to unlock multiple nearby turnstiles before triggering the door contact and engaging the built-in anti-passback functionality. Resolution The simplest solution to the issue described above is to configure the door objects WITHOUT a door switch/contact, this, however, is not always possible depending on on-site requirements. A second solution is to take control of the doors using Plain English. The solution presented here is for a bank of three turnstiles, (A, B, and C), it uses a PE program per turnstile. The solution can easily be adapted for a bank of less or more turnstiles. NOTE: The PE programming here is provided as a sample, for guideline purposes only, the programs are not intended as a complete solution, significant modifications may be required for site deployment.

Issue What are the rules for inheritance in TGML? Environment TGML editor Cause In order to create TGML components that function as designed,  it is important to understand the TGML rules for inheritance Resolution Attribute inheritance means that a child element inherits (gets) the attribute value from an ancestor element if the attribute value is undefined (omitted) and if the attribute has been specified for an ancestor (any of the parents). In the example below, Rectangle will inherit the Fill value from the component.

Issue When emailing an alarm from the ENC the timestamp is always the time the alarm occurred; even when the Alarm email is due to an acknowledgement or return to normal. Environment G3, ENC's, JACE's Cause The default "body" property of the EmailRecipient contains only the %timestamp% which represents when the alarm occurred. Resolution Additional parameters can be added to the EmailRecipient "body" property to provide the "return to normal" and "acknowledged" timestamps. The return alarm timestamp can be added with %normalTime%. The acknowledged timestamp can be added with %ackTime%.
