Issue Changes to the Set Space Temperature do not work. Environment DC1100 DC1400 Controller Compensator Optimiser Setpoint Cause The pump overrun is timing down and will not allow the controller to act normally until it is complete. Resolution If the "Set Space Temperature" value is modified, then after the rotary switch is returned to "Auto", the user must wait until the Pump Overrun function has timed out. Where adjustments are generally being made, it is recommended that the Pump Overrun setting is set to 1 minute until  testing has been completed, after which it should be return to its required setting. To change the Pump Overrun setting carry out the following: Turn the rotary switch to "Setup". Select "System Menus" then "Alter Settings", and then enter the password of 0112. Select "Compensator", then "Set-up Menu", and then "Pump Overrun". Note the current value then change it to 1. On completion of the tests return the setting to its correct value.

Issue What is the maximum number of registers that can be read/written using the multiple read/write function codes in Modbus Product Line EcoStruxure Building Operation Environment Building Operation Automation Server Modbus Register Groups Cause When deciding how to group registers using a Modbus Register Group, what are the maximum number of registers that can be grouped. Resolution There is a limit to the number of packets that can be polled in a single packet, however, if this number is exceeded then two or more polls will be made (blocks).  The nominal Read multiple registers maximum is 125 16 bit registers (250 8-bit bytes, so the register count will vary for 32 and 64bit polls).  The Register Group Properties Tab shows the number of blocks being polled. The Modbus register grouping function has a direct effect on system performance. A poorly grouped device can easily increase the overall poll time as points, or blocks, in each Modbus network are polled sequentially.  See the section "Batch Read Function" in the EcoStruxure Building Operation Technical Reference Guide for full details. Note: Multiple group writes are not possible and are not controlled via Modbus Register Groups.

Issue MNL-800 LON SNVT Programming Standards Environment Workplace Tech Tool software (any version) MNL-800 controller application Cause Problems occasionally arise as a result of improper LON SNVT programming and configuration in the MN-800 device application.  These issues include problems with the re-commissioning of the updated controller and potential network variable mismatch situations. Resolution  The following standards will prevent these problems from occurring. Network variables MUST be manually indexed. This prevents issues with the network variables becoming renumbered when application programming changes are made. (See NOTE 1) Change the application "Program ID" any time network variables are added or removed from an application.  To change the "Program ID" use the WPT Hardware Wizard,  (See NOTE 2) Select Hardware Wizard from Application Menu Click [Next] in MicroNet Setup Wizard screen Change the displayed program ID by entering a different program ID or adding a suffix letter/number. Maximum length is 8 characters. Click [Finish] to save the changed program ID and exit the MicroNet Setup Wizard.  In addition, one method of minimizing the need to repeatedly change the "Program ID" as the application is developed and debugged is to add a few extra common SNVT input and output definitions when first creating the application, leaving them unconnected to the application program.  If one of these SVNTs is needed, it is available in the LON network image (XIF file) and it is not necessary to change the "Program ID". If the MNL-800 controller has firmware version 2.0 (or later) installed, the standard nci network variables do not have to be indexed as the highest numbered SNVTs in the application.  It is perfectly acceptable to number them as the first 17 indexed SNVTs. Note that there are 17 standard network variables (12 nci, 2 nvo & 1 nvi), not just ten nci SNVTs. SNVT variable names should be limited to 16 characters or less.  Longer names are accepted by the WorkPlace Tech programming tool but the names will automatically be truncated by the LON Network Management tool when commissioning the controller. In addition, when programming the MNL-800 applications with the WorkPlace Tech Tool version 5.0, or later, it is not necessary to put each MNL-800 application in a separate project. NOTE 1: If using the WorkPlace Tech Tool version 5.8 or above, you can use the "Object Indexer" to automatically number all the network variables for you.  This tool also includes functions for detecting duplicate SNVT index numbers and for detecting gaps in the assigned index numbers. NOTE 2: If using the WorkPlace Tech Tool version 5.8 or above, you can set an option in the Hardware Wizard to automatically generate a new ProgramID and reindex the network variables when compiling the application.  Please be aware that this automatic generation of the ProgramID will require the Echelon network image for this device to be updated in any Echelon compatible network management tool.  Please refer to the documentation for the network management tool to determine what actions will be required. For example, if Niagara was used to manage the LON network, then the old shadow will need to be deleted, a new one added, and the device points rediscovered and the device re-commissioned.  

Issue Need to Export a Trend log file without using Reports Server Product Line EcoStruxure Building Operation Environment SmartStruxure Workstation Cause Customer needs a log file, but does not have Report Server Resolution In Workstation, right click on a Trend and create a new Trend Log List View Once the List populates, click on the Icon showing a green arrow labeled .csv Save the file to an appropriate location. If this is a frequent action, save the Trend Log List View Please Note that this feature is not available in WebStation  At v2.0 WebStation introduced the option to export to Excel, creating an XLSX file, this can be opened in Excel and saved as a CSV if required (this option is not available if WebStation is directly logged on to the AS/P/B)

Login Screen appears as expected, but when attempting to log in with the user name/password; It times out and comes with the message 'Failed to establish connection with server.' Product Line EcoStruxure Building Operation Environment Building Operation WebReports 1.1 / 1.2 Cause The error is most likely due to ports been blocked and/or the incorrect port settings entered during the WebReports installation process. When installing (or upgrading) WebReports, you must enter this information on each occasion as this information is not retained from previous installations. If you need to change these settings, then you should follow the procedure detailed below. Resolution If installed on separate machines, then check the firewall settings and ensure the ports used for the Enterprise Server and the Report Server are not blocked.  If this does not resolve the issue or if you are running both the Enterprise Server and Report Server on the same PC, then the Enterprise Server port configuration during the WebReports installation may need to be changed.  This is achieved as follows: this, and follow these key steps: Run the WebReports Installation setup program, and at the Setup Type prompt, select Upgrade from... Proceed through the other options as normal. Once you reach the Reporting Agent setup, make sure you enter the correct URL (path and port number - this is unique for each installation) used during the Enterprise Server setup. Continue through the other settings as required - Ensure that any Path and URL ports are set correctly.  Once you complete these settings, the WebReports Installer package then goes through the following checks and installation: Checking Installation Requirements Pre-upgrade Configuration Installation of Reporting Agent, WebReports, and WebReports Service Post-Installation Configuration Installation PublishedReports After the above steps, the upgrade is completed. This will now allow login to the WebReports URL using your web browser. For additional assistance in installing/upgrading WebReports, refer to the online help website. 

Issue What are the intervals for Trends when using StruxureWare Building Operations Product Line EcoStruxure Building Operation Environment Enterprise Server or Automation Server Cause Questions regarding what the interval in time is for trending Resolution Intervals can be in Days, Hours, Minutes, Seconds, and Milliseconds. . Trend logs can be of different types and used for different purposes. All logs in StruxureWare use circular storage. The interval trend log collects data at a specific time interval. Each logged value is stored as a record in the trend log. Use this trend log when the logging interval is less than 1 hour. You create interval trend logs using WorkStation or WebStation. In WorkStation, you configure the properties of the interval trend log to meet the specific needs of your site. The interval trend log does not record the values between the intervals. An interval log checks the monitored value at each interval and records the new value if it differs from the previously recorded value by more than the delta. Delta is the difference between the current variable value and the last log value. To log a variable according to the time interval, use a delta of zero. You use an extended trend log to transfer records from a trend log. An extended trend log can be connected to a trend log or connected in a series to another extended trend log. Only one extended trend log can be connected to a trend log. You create and configure extended trend logs using WorkStation. The extended trend log is often saved on a higher server level with more storage capacity than the server of an ordinary trend log. This extra storage capacity enables the server to store more records before it overwrites old ones. The extended trend log can be viewed in a trend log list or a trend chart. Trend log lists and records can be exported in two different formats: CSV (Comma separated values) is a standard file format for digital storage of data structured in a table of lists form. The CSV format can be used by Excel and in databases such as SQL. XML (Extensible Markup Language) is a standard file format for structured data and can be use with a lot of different tools. One last suggestion is the number of records, depending on how many records you want to store is important. For example: a single one minute interval Trend Log, and for 66 day, that would be 99,792 records. The maximum is 100,000 on an AS, so take this into account when configuring. This is why Extended Trend Logging is important. Check out Maximum number using StruxureWare Building Operation (Scalability and Capacity) for information on trends and extended trendlogs.

Cause The px file did not copy correctly. Resolution There are three possible approaches to recover from this situation, as follows: Try copying the file again.   Open the px file with a text editor. It might be possible to determine what was either not copied at all, or what might have been corrupted during the copying process. The example shown below is part of the BoilerRoom.px file from niagara-3.6.47 \ stations \ demo \ px \ plant. Lines 489 through 495 contain 'closing tags' for the Canvas Pane, Scroll Pane, Border Pane, content, and px statements that were opened at an earlier point in the px file. If one or more of these 'closing tags' were not copied, or were somehow corrupted during the copying process, the error would result .  If necessary, restore the px file from a backup.

Issue Running I/NET Seven as a service on Windows Product Line TAC INET Environment I/NET Seven All supported Operating Systems Cause When you log out of Microsoft Windows or restart the computer, all running processes are shut down. These processes are not resumed at log on or at restart. You have to start I/NET manually again. To get I/NET to start up when the computer restarts, you can run it as a service. Running a program as a service means that it runs in the background, but it is not visible on the Windows task bar. Resolution Use the INET Run Mode tool available on the Community.  Alternatively, you can perform the following steps to set/unset the InetIoSrv.exe as a service or application. To register I/NET Seven to run as a service Open a Windows command prompt. Go to Start > Run and type "cmd" Use right-click on the command prompt and select "Run as Administrator" Use commands cd.. (to go back one directory) and cd (to go into a folder) to navigate to the following location: C:\Program Files\INET Seven\ If this is being run on a 64 Bit OS, the location then would be: C:\Program Files (x86)\INET Seven\ Type the following command. This will unregister I/NET as an application inetiosrv /unregserver Type the following command. This will register I/NET to run as a Windows service inetiosrv /service To verify the changes have taken effect Right-click on "My Computer" and select "Manage" Select Services and Applications > Services Look for Inet7Iosrv. It should be set to Automatic. You are now running I/NET as a service. IOSrv will now be running in the background when the PC boots up. This does not require a Log On to the PC, however, you will have to Log On to the PC as a user to launch I/NET or AMT from the desktop icon. You will notice that IOSrv has been logging all AMT transactions, messages and alarms. The SQL Server and Agent were also running in the background receiving data to the database. To set I/NET back to running as an application Open a Windows command prompt. Go to Start > Run and type "cmd" Use right-click on the command prompt and select "Run as Administrator" Use commands cd..
