  Issue Is it possible to host the same third party BACnet device on the AS-P private networks on multiple automation servers, which are all connected on the same network? Product Line EcoStruxure Building Operation. Environment Building Operation Automation Server Premium Cause The design in question is a 3-storey accommodation building which includes 1 x BMS panel/AS-P per level. However, only 1 x Mitsubishi EW-50E BACnet gateway is being provided for the building. Resolution It is possible to host the same 3rd party BACnet device in multiple AS-Ps. Some caution is required, however, because if the user makes changes to an object in that device through one AS-P, that change may not be reflected in other AS-Ps. When viewing runtime variables, such as 'Value' and 'Status Flags', this is not a problem because the EBO server will always get new values from the wire. Where the problem can present itself, is when changes are made to configuration values because these are only updated in an EBO server during an upload operation. For example, if you set the hi-limit and low-limit values in an analog-value object from one AS-P, those values will not be updated in other AS-Ps until you do an upload of that object.   The other place where this problem may present itself is in schedules. An EBO schedule only writes values to a device when that value changes. For example, if you have a schedule configured to change the setpoint to 65 degrees at 5pm, EBO will only write a value of 65 if the current 'local' value is not 65. If this schedule only writes 1 time per day and someone has set the value to 70 from another AS-P, the first AS-P does not realize the value has changed so that schedule will not generate a write request to set the value to 65 (it will stay at 70). However, if you have a program or trend-log monitoring the value, the AS-P will be tracking that value and realize it is not 65 so you will see a write request at the scheduled time.   The system works this way because reading all values of all devices and all objects all the time is simply not practical. As long as the user is aware of how the system is designed, they can avoid these potential issues.   Make sure to use Static IP, so IP do not change, or you get multiple DHCP servers on the same network.   Another alternative is to host the BACnet device in one AS-P only, then using internal bindings to share the data with other AS-Ps.

Issue The first batch of White TRCs (produced in 24H1) could appear too bright in some low-light level situations. All future batches (post 24H1) do not have the issue. See the precise list of affected serial numbers in the appendix section below. Product Line EcoStruxure Building Operation Environment SpaceLogic Touchscreen Room Controller Cause The housing color is set in the device’s manufacturing configuration to tell it what color the screen bezel is (black or white). White TRCs produced with an incorrect housing color will read a higher value for light level. This has a direct impact on the backlight dimming levels, and the only effect will be the screen staying brighter in dark rooms. Resolution Customers experiencing brightness issues may simply adjust the backlight brightness parameters to a lower value, which are configurable in the TRC configuration screens and via BACnet/Modbus. This would reduce the overall brightness of the devices immediately, without fixing the housing color. We recommend going with a permanent fix, by setting the housing color via the USB port. The steps to fix this permanently would be: Connect USB-C cable to TRC Log in as an administrator into the TRC’s configuration screens (to enable USB connection) Open a terminal app like hyperterm or putty, with settings: Speed (baud): 115200bps Data bits: 8 Stop bits: 1 Parity: None Paste in the command: #001000061009FE00009C! Device responds: #000E00071009FE0051! To confirm or test, paste in the command: #000C00001009FEE8! Device responds: White housing: #001200011009FE000000F9! Black housing: #001200011009FE000001FA! Examples Below is an example of 4 white TRCs: The two (2) outermost devices are too bright (leftmost and rightmost white TRCs). The two (2) devices in the middle have been corrected to show adequate brightness. Appendix Since the Touch Room Controller’s serial number includes the date code, knowing whether a unit is impacted is very straightforward. Follow these instructions to determine if the unit of interest is impacted: Retrieve the serial number from the unit you suspect has the incorrect housing color. Example: FL24075TRC00002 Examine the serial number date code, wrapped between the “FL” and “TRC” substrings. Example: 24075 Decrypt the date code, using this logic: 24: year 2024 07: week 07 of 2024 5: day 5 of week 7 of 2024 If the date code is between the values 24074 and 24285, the product is impacted. Products outside of this date code range are not impacted, and no fix to housing color will be needed.

  Issue Identifying table sizes is useful when managing Security Expert databases Product Line EcoStruxure Security Expert Environment EcoStruxure Security Expert Microsoft SQL Server Cause Managing the size of a SQL database is crucial to system performance and archiving so understanding which tables are the largest provides needed data Resolution A report can be run from SQL Server Management Studio(SMSS) on the Security Expert and Security Expert Events databases to provide table sizes. Open SMSS Right-click on the database the report is needed (i.e. Security Expert or Security Expert Events) Select Reports> Standard Reports> Disk Usage by Table Scroll through and observe which tables contain the most data Examples: Security Expert DB Security Expert Events DB Print or Export the report to a file if necessary Print Export to Excel, PDF or Word Right-click on the data results and select Export Note: The disk usage built-in report was implemented in SQL 2008 and above. 

Issue In some projects there is demand for importing a large number of individuals from an existing spreadsheet for individual information at one time. Product Line TAC INET Environment I/NET Seven Revision 2.xx and higher Microsoft SQL Server Management Studio Express Cause In some cases the customers have a spreadsheet or database of employees and/or users which they want to quickly import into their I/NET Seven Access control database. Resolution The whole process is to import the data from the excel file to the IDWorksView table of SQL database of I/NET. The steps below needs to be followed: Prepare the Microsoft SQL Server Management Studio Express. Click here to down this tool for version 2005 free of charge. If for version 2008, click here to download. Then install this tool. Download the individual spreadsheet Excel template and SQL script here. Save to the C:\. Ensure that the Tenant, Group have been added in I/NET already. Also ensure that all the card numbers in the spreadsheet don't conflict the ones already in I/NET. Enter the individual information into this template. If there are photos for individuals, the folder of the photos also need to be entered. Open the Microsoft SQL Server Management Studio Express and connect to the database. Find the InetDb database, and open the SQL script just downloaded from the File menu. Click Execute to run the script. Then if without any problems, the successful result will be shown in the output message window. The next step is to get the imported data downloaded to the controllers. For each SLI perform a station SAV and station restore – it may take some time for all this information to be downloaded to the DPUs and may fail in some instances.  You may also notice the system slow up for some time (hours) until all of this information has been successfully downloaded to the controllers.  It may also be necessary to force the data into the DPU by performing staggered DPU Restores on specific doors that are experiencing incorrect functionality.  There is also a method that download the imported data without any operation in I/NET software by a function called Automatic DPU Restore. Refer to Automatic DPU Restore and Individuals added via Datacard ID Works are not getting access to doors for detailed information about how to set Automatic DPU Restore in I/NET. This is the method using SQL Server Management Studio Express. The Microsoft Access can also be used to do the importing work. Refer to How to import a large number of Individuals into an I/NET Access Control database for detailed information.

The Reports Server indicates that the database is full.   This view will be shown when logging into the WebReports interface. If this chart is not shown, the PC is not running an Express edition of SQL. Product Line EcoStruxure Building Operation Environment Reports Server Cause In most instances, the data that quickly fills the SQL database are Events. Event data fills the SQL Database and prevents log data from passing to the Reports Server database. If the data has filled within a few days, this would indicate an issue, and contacting your local support is the best option here. The Process below allows the user to stop the reporting agent from passing specific information to the Reports Server. If the data files are due to the amount of data stored, then an upgrade to the Standard/Full version of SQL is recommended.   Resolution To verify that the Events table is the likely cause of the SQL filling up, there are Standard Reports in the later versions of SQL.  The below example uses SQL Server version 13.x and shows the "Disk Usage by Top Tables."   If the Standards Reports are not available, then use the following article Building Operation Reports SQL Database Full, for instructions on how to show the details for each table.     The Process below allows the user to stop the reporting agent from passing Event information to the SQL Database: Download the latest SBO Reports Agent Config tool from the community. Load the Tool onto the Reports Server PC. Stop the Reporting Agent Using the Tool Press F7 to get to the Advanced Agent Configuration Page Change the numEventRecordToRead property to 0. This will prevent future event data from being written to the Reports Server database. Press Ok Under the Maintenance tab of the tool - there are two options under Events  Delete future events, alarms, and trends  Delete events and alarms older than... Restart the Reporting Agent This will stop any further Events from being passed through to the SQL Database.

Issue Methods are needed to purge access events with Security Expert running on SQL Express Product Line EcoStruxure Security Expert Environment EcoStruxure Security Expert Microsoft SQL Express Microsoft SQL Server Management Studio (SMSS) Cause Security Expert operating on Microsoft SQL Express can exceed the 10GB limitation depending on configuration and system size Resolution There are several things to consider when configuring Security Expert when running on Microsoft SQL Express which has a 10GB size limitation and other limitations. This article will address the following items: Backup of the SecurityExpert and SecurityExpertEvents databases, review of the database file sizes, automatically and/or manually purge access event records, shrink the database(s) to regain hard drive space, and return the system to operational status.   1. Create database backups for the SecurityExpert and SecurityExpertEvents databases (Select a method) a. Configure options in Security Expert under Global Settings> General> Main Database Backup b. Use Microsoft SMSS. Right-click on the database, select Backup and complete the steps Note: It is recommended to save the databases as different file names than the original database  names to keep a copy of the database prior to deleting records. 2. Examine the database file sizes a.  Observe the file size In Windows Explorer, Navigate to:  C:\Program Files\Microsoft SQL Server\MSSQL(version).SECURITYEXPERT\MSSQL\DATA Observe the file size of the SecurityExpertEvents database If the site is using Microsoft SQL Express and the database file size is close to or over 10GB, events will need to be purged. Note: SecurityExpertEvents files. One file is the transaction log and the other is the data file. The file highlighted above is the data file. b. Check the Windows Application log: There may be a message with evidence of database size issues in the Windows application log, i.e. "Primary Filegroup is FULL" 3. Check the database recovery model configured for both databases in SMSS If "FULL" is used instead of SIMPLE the database(s) will grow quickly See the following KB article for more details on Recovery Mode: https://community.se.com/t5/Building-Automation-Knowledge/Security-Expert-functionality-starts-to-degrade/ta-p/441818 An article with additional details about the database table sizes: https://community.se.com/t5/Building-Automation-Knowledge/Security-Expert-Database-Table-Sizes/ta-p/482178 4.

Issue All Controllers appear offline with any associated I/O showing a status of “Unknown”. The Security Expert Event Service's memory usage builds up until it gets close to 2GB when the controllers go offline.  Restarting the Security Expert Event Service brings the controllers back online. After a period of time the issue re-occurs and controllers again appear offline. Product Line EcoStruxure Security Expert Environment Security Expert Cause A potential memory leak in the Event Service would cause the service to stop working resulting in controllers appearing offline. Resolution 1. Upgrade to Security Expert version 4.3.370.1 or greater as discussed in known issue. 2. A potential workaround to mitigate the frequency of the problem is to disable the Event service from using MSMQ. As long as there are no site integrations using MSMQ then this option can be disabled in the Event Service Config file. Go to ..\Program Files (x86)\Schneider Electric\Security Expert and edit the SecurityExpertEvtSvr.exe.config file. Search for the MSMQ key <add key="MSMQ" value="1" /> and replace it with the following. <add key="MSMQ" value="0" />

Issue Extended Jace 9000 Commissioning Time. Product Line TAC IA Series Environment I/A Series Jace 9000 Cause With the release of the Jace 9000 using Ubuntu Core 20 Linux as it’s operating system the commissioning/upgrade times increase as compared to the previous Jace 8000. Initial commissioning times can take longer then 15 minutes to finish. There are scenarios where multiple reboots are needed after the initial commissioning is completed. Once the commissioning has been completed for the Jace 9000, boot times should be significantly lower. Resolution Users will need to reboot their Jace at least twice and will need to set more time aside for commissioning of the new Jace 9000s. Please allow for a minimum of 15 minutes for commissioning. If you continue to experience issues with bootup or commissioning on the Jace 9000,  please contact your country level product support. Please note that the JACE-9000 does not print a lot of output on the debug port when you cycle power so give it time to fully bootup.

Issue Incorrect Default Gateway setting may prevent communication with the JACE-9000 Product Line TAC IA Series Environment I/A Series Jace 8000/9000 Cause The Jace8000 and Jace9000 both have primary and secondary LAN adapters. Previously, Workbench prevented users from some invalid IP configurations, but current versions of Workbench, when connecting to a 9000 will allow invalid configuration in the default gateway. Resolution In the 9000, a user can set different default gateways for the Primary (en0) and Secondary (en1) ports. This should not be allowed on a single network device, and leads to unpredictable behavior when routing. Compare the location of the IPv4 Default Gateway in the TCP/IP Configuration of the Platform on a 9000:      And the same page as seen in the 8000: In future versions, this will be changed, but users should avoid invalid configurations in the affected versions. When configuring both LAN ports for use on a 9000, only enter a value for the default gateway field in one adapter. Leave the other intentionally blank. It does not matter which is given a default gateway and which is left blank. Note: Sometimes, when an Adapter has the Default Gateway, you cannot connect to the other Adapter (despite correctly being on that Adapter's local subnet). These symptoms can be triggered by the Ethernet "link" (active connection) toggling up or down.  The link state can change whenever: the JACE is rebooted or power-cycled; and/or the Ethernet switch ("hub")  is rebooted or power-cycled; and/or the Ethernet cable(s) are un- or re-plugged (at either end). In some cases, the symptoms can alleviated by toggling the Ethernet link state, in the ways listed above.
