Issue When connecting MP-C controllers in a daisy chain, do they act as a repeater and boost the signal thus allowing total network distances of greater than 90 meters. Product Line EcoStruxure Building Operation. Environment Building Operation Multi-purpose Controller. Cause Each MP-C acts as a switch and decodes and generates a new fresh packet. Resolution Maximum 100 meters between each device when using daisy chain when connecting MP-C.

Issue With the M42 series actuators being obsolete, they need to be replaced. Environment M42 Actuator M42/230 8401000000 Actuator M42/230 8401300000 Actuator M42P/24 8402100010 Actuator M42PBB/24 8402400010 TAC Forta series M9/EM9 Cause Replacement of obsolete actuators. Resolution Spare part for actuator for valves with linear moving stem the complete actuator TAC Forta should be used. When a 230 Volt actuator is requested the TAC forta needs a supplementary 230/24 Volt transformer. Depending on the electrical installation certain modifications may be necessary. For valves with rotating stem, actuators M9/EM9 can be used.

Issue How to create custom reports in Building Operation WebReports Product Line EcoStruxure Building Operation Environment Building Operation WebReports up to version 3.2.  Note: WebReports is no longer included in Building Operation 2022 and above. Cause Custom reports are typically created by modifying another report and then saving these changes. Typically used are the factory-supplied reports as the base for a new report then enter the filtering criteria that are required to be used in the new report. Assign a unique name to the custom report and save the new report as a dashboard or prompted report.  There may be a need to create a report not based on any of the standard reports provided in these Report Packs, this article covers this process. Resolution To create a non-factory-supplied report within WebReports it is necessary to use an editor.  Since WebReports use Microsoft Reporting Services it is recommended to download the Microsoft SQL Server 2008 R2 Report Builder 3.0 or MS MSQL Server 2012 Report Builder.  This is a free tool provided by Microsoft that provides an intuitive report authoring environment for business and power users. This download provides a stand-alone installer for Report Builder 3.0.  Please note that Product Support does NOT provide support for Report Builder.  After downloading and installing the Report Builder application, the steps are as follows:  Each of these steps is also located on the Building Management System WebHelp site, a link for each of these steps is provided for additional reference and guidance. Start Report Builder and create a new blank report, see Creating a Basic Report for the steps.  After Creating the report create a data source that connects this report to StruxureWareReportsDB, see Creating a Data Source for these steps Then create the Data set, so add to the report which tables, views, stored procedures, and fields from the StruxureWareReportsDB are required to use in your report, see Creating a Dataset for these steps. This data can then be added to the custom report as required.  See Setting Up a Report for an example of setting up a report. See Adding an Image to a Report  on how to add images to the report  The new report now must be deployed to the Reports Server where it can be accessible to WebReports. To complete this procedure use SQL Server Reporting Services Report Manager. See Deploying a New Report to the Reports Server to view these steps in detail.  Finally, the report must be synchronized in WebReports to be deployed and therefore appear in the WebReports Reports Tree. Use WebReports with a Web browser to complete this procedure.  See Synchronizing WebReports with a New Report for the steps to complete this. Once all these steps have been completed successfully the new Report should be visible in the tree - the placement of these reports will depend on where they have been uploaded in step 5 above.  See the image below:

Issue Can the Execution Precedence determine the priority of a program binding to a value? Environment SBO Function Block and Script programs Cause Clarification on the function of Execution Precedence is required. Resolution In both Function Block and Script programs there is an attribute called Execution Precedence, this can be set in the program "Properties", Basic tab. For a Function Block program:    For a Script Program: Execution Precedence determines the order that the programs will be run, the lowest numbers will be run first. In the 2 screenshots above the Function block program (Value 1) will be run before the Script program (Value 20). This can be used for applications where a calculation is done to generate a value, that is then used in a second program e.g. Calculation of a compensated setpoint, that is then used in a PID control program as the reference value. The PID program must have a higher Execution Precedence than the setpoint calculation. Execution Precedence does not affect priority. If the outputs of 2 programs are bound to a single value, both programs will be trying to control the value and give an indeterminate result.   To combine the outputs of 2 programs the programmer must use the appropriate logic to determine how the 2 signals should be combined for the application. So for Binary values use one of the logical operators: AND, OR, XOR etc, For Analog values combine the 2 results with Max, Min, Average etc as required.

Issue When a DELR or DELI block is used with a comparison operator to detect a change of value in the output of a function block, the output of the comparison operator should go ON for one scan when the source output value changes. If the source function block is a PVR or PVI this does not occur. For example: This code does not work This code works Product Line EcoStruxure Building Operation Environment StruxureWare Building Operation version 1.3.0 or earlier Function Block Editor Cause There is a defect in StruxureWare Building Operation version 1.3.0 or earlier that causes this behaviour when writing to a public PVR or PVI block in a Function Block Program in the ES or AS directly from the Workstation. Resolution This defect has been logged with Quality Center and will be fixed in SmartStruxure version 1.4.0 Meanwhile, the workaround is to insert any compatible block immediately after the PVR or PVI.  For example: The inserted block could be an operator, an expression block or even another DELR. Although the workaround works, the preferred practice for new applications would be to replace the PVR with a RI and bind the RI to an Analog Value in the ES or AS. This defect does not occur in Menta programs in Xenta controllers, including those written in the SmartStruxure Menta Editor.

Issue One or more inputs on the SP-ACX will randomly report as open for a brief moment (a second or less), This can result in unauthorized door access if for example the input is associated with a door Exit Request. Product Line EcoStruxure Security Expert Environment SP-ACX Cause Electrical noise in wiring Resolution Increase the Alarm input speed, issue has been seen with Alarm input speed set to 0, increasing the input speed to 1 second typically resolves the problem.

Issue How can I find out whether the EBO 2022 multi-version support applies to AS Classic module?  Does it apply to all the AS, AS-P, and AS-B modules? Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Server Building Operation Automation Server Cause The EBO 2022 Release Note describes that the EBO 2022 Device Administrator software is not supported on the original AS classic (part number SXWAUTSVR10001) but there is no description of the software backward compatibility of the EBO on AS classic. Resolution An AS classic can continue to exist in a multi-version system; the maximum version an AS classic can operate at is 3.1.2. It is nowhere implied that it is not supported under a multi-version setup. The statement “EBO 2022 does not support AS classic” in the EBO 2022 Release Note is misunderstood. It simply means that one cannot install EBO 2022 on an AS Classic, the same as the previous EBO 3.2 version. Note that the AS Classic will not inherit any features introduced in later EBO releases when operating in a multi-version system.

Issue When configuring the in-built Visitor Management System (VMS) there is no report mechanism under the Visitor tab to show visitor access. Product Line EcoStruxure Security Expert Environment Security Expert Client Visitor Management System Cause Reports for visitors are part of the list of the Report types under the more general User reports Resolution Visitor reports for visitors using the in-built VMS can be generated with a User Report by selecting one of the following Report Type options: All current visitors All overdue visitors All visitors by date Visitor user report setup This can then be further configured to your requirements by editing the report filter.

Issue Building Operation WorkStation freezes and crashes. The stack trace shows: System.ComponentModel.Win32Exception: Not enough quota is available to process this command Product Line EcoStruxure Building Operation Environment Building Operation WorkStation Cause This is an error from Windows system: Not enough quota is available to process this command There are two potential causes for this error: Windows does not have enough virtual memory for all of the processes that are currently running on the machine or Windows is running out of other resources such as: disk space, handles, GDI resources, process message queue or something else. This error turns up on a lot of programs in Windows intermittently, such as Windows File Explorer. WorkStation freezes (usually because its waiting on the server) and the user tries to do a 'soft' shutdown (not a kill process) of WorkStation in the Task Manager. The Windows OS then sends instructions via the message queue (to simulate a user press on the "red cross" button on upper right in caption bar) which in turn leads to this quota error. Resolution If this error is seen, Microsoft recommends closing some applications and trying again. If you still get this message, increase the size of your paging file.   In the Taskbar Search, type “Advanced System“. You will see View Advanced System Settings. Click on it. Or you can navigate to it via Control Panel In System Properties, click the Advanced tab In the Performance section click the Settings button Performance Options will open. Click the Advanced tab Here, under Virtual memory, select Change Uncheck Automatically manage paging file size for all drives Highlight your Windows system drive Select Custom size Change the Initial size value and the Maximum size value to a higher value Click Set Finally, Click Apply/OK all the way  

Issue Why do controllers go into bootloader mode? Product Line Andover Continuum Environment Bootloader NC2 BCX CX99xx CX96xx i2 b3 Cause Continuum controller are placed into bootloader mode if they repeatedly hit a firmware level exception. An exception is when the controller tries to do something that cannot be done.  Some examples of an exception are... A controller tries to read from memory that it cannot read from. A controller attempts write to memory that cannot be written to. On startup, flash generation controllers load the application from flash RAM.When they hit an exception, older, non-flashable controllers would simply clear the application software from ram, power up and wait for the software to be loaded from the front end.  If there is a bad application there needs to be a means by which a user can intervene before the application is loaded so that the controller firmware can be reloaded or upgraded.  When a flashable controller hits more than three exceptions within a ten minute time period the controller is placed into bootloader mode intentionally. Resolution When a controller repeatedly goes into bootloader mode it is time to take a close look at environment which might be driving the controller to hit exceptions A controller usually goes into bootloader mode due to environmental issues such as Heavy ARP traffic Controller grounding Controller power issues Problems with the communication bus. A controller that repeatedly hits exceptions is placed in bootloader mode by design.  Flashing a controllers firmware is the only way to get a controller out of bootloader mode. 

Issue How to connect a SpaceLogic IP Controller via MSTP Product Line EcoStruxure Building Operation Environment Workstation Automation Server (ASP/ASB) Space Logic IP Controller RS-485 Adapter Cause Only certain SpaceLogic IP Controller models and versions support the new BACnet MSTP Adaptor and details are required on how to configure these controllers for BACnet MSTP. Resolution The following video will illustrate how to: Configure ASP/ASB for BACnet MSTP Communication. Configure a SpaceLogic IP Controller as a BACnet MSTP device. Discover the SpaceLogic IP Controller on the BACnet MSTP network. Things you need: Software EcoStruxure Building Operation Workstation 2022 Building Commission Application (available from Google Play, Apple Store, or Microsoft Store) Hardware ASP/ASB version 4.0 or higher RP controller (hardware version 10 ) RS-485 Adaptor (Isolating or Non-Isolating) RJ45 UTP Straight Through Cable (12"/300mm or less) Note: - if the RP controller does not show MSTP settings check the Space Logic IP controller firmware release notes and install firmware corresponding to the EBO version.  For example firmware versions 3 and below do not have settings for MSTP configuration.

Issue While RS485 requires a daisy chain topology, can b-Links be daisy chained along with b3 controller in the BCX segment. Product Line Andover Continuum Environment MSTP b3 B-Link RS485 Cause While RS485 requires a daisy chain topology, the addition of b-Links to a RS485 bus makes the limitations of bus wiring less clear. Resolution RS485 is an electrical standard.  The key to understanding RS485 topology conformance is to understanding that each segment of the RS485 bus must have a daisy chain topology with the required termination resistors installed at each end of the segment. The bus segment that runs from the BCX controller to inputs of several b-links and or b3 controllers would constitute one segment.  As long as this segment has a daisy chain topology with the proper termination resistors installed it conforms to the requirements of RS485 bus wiring. Each outgoing leg off of any given b-Link constitutes one distinct and separate segment. As long as this segment has a daisy chain topology with the proper termination resistors installed it conforms to the requirements of RS485 bus wiring.

Issue Need information on programming holidays and special dates Product Line EcoStruxure Access Expert Environment Access Expert Hosted software V3 Resolution Programming Holidays and Special Dates   Overview   Holidays are exceptions to a normally scheduled interval. Feenics has made several fundamental changes to the holidays within the Keep by Feenics System. This article will walk through how the new holiday sets work and how to implement them. The holidays apply globally to all schedules.   Updating    The launch of the new holiday system requires a system upgrade within your instance. This upgrade only needs to occur once and is irreversible. To upgrade, click the "Update Holidays" button.   Note: Before you begin converting holidays, there can be no more than 8 holiday sets in the older system for the update to work.   Once that button is clicked, a warning will pop up letting you know that the process is irreversible. Click OK and your instance will be updated.     ***Note: Customers within an Enterprise instance will need to apply this update to ALL shared instances and the Enterprise instance separately.   Adding Holidays   Holidays are added to the system through the "Add Holiday Duration" button. This will add a holiday interval to the system. Holiday Durations   Holiday Durations are days in the system on which, the schedules should not activate. To add a Holiday, click "Add Holiday Duration", then name the day. This day will prevent all schedules from activating unless added to the "Always Active On" column in a schedule. Holiday durations are limited to 255 per instance.  Display Name: The name of the holiday interval, i.e. Valentine's Day, Halloween, Veterans Day. Start Date: The date the holiday interval begins on. End Date: The date the holiday interval ends on. (If the start and end date match, the holiday will be for that day only). Special Date: This flag inverts the behaviour. If this holiday interval is assigned to a schedule interval (via Holiday Groups), the schedule interval will activate for that day. Holiday Group: This selection allows the user to group holiday intervals into sets.  Tags: As in the rest of keep, tags allow for organization and permissions to be set by these groupings.   Holiday Groups   Holidays can be grouped together by using holiday groups. These groups are edited by selecting the "Edit Holiday Groups" button and modifying the Group Name. Holiday intervals are then added to the group by assigning them in the Holiday Group column of the holiday interval. ***Note: The shared holidays between groups should be in their own group. This will allow the non-shared holidays to be applied to schedules correctly.   Applying Holidays   Holidays apply globally to all schedules. A holiday Group can be added to a schedule interval to tell that interval to ignore that holiday.   ***Note: If a holiday exception is added to a schedule interval, the schedule will activate on the day of the holiday, regardless of the day selection on the schedule interval. Special Dates   Special Dates can be used to activate a schedule interval for a day or group of days regardless of the other intervals within the schedule. To add a special date, open the Holidays page and add the day(s) as a holiday interval, then check the "Special Date" box. Add the special date(s) to a group on its own.
