  Issue How can I troubleshoot a communication issue with the Smart Connector. Is there a log available within the AS or ES that shows the Smart Connector communication. Product Line EcoStruxure Building Operation Environment Building Operation Workstation Building Operation Automation Server Building Operation Enterprise Server Cause When troubleshooting Smart Connector issues in an AS or ES it can be helpful to see the communication between the Server and the Smart Connector device to help identify this issue. The trace log within both server types is available and is configured as described below in the resolution. Resolution Open Workstation and navigate to [AS/ES name]/System/Modules/Trace/Loggers/nsp/nsp.csc/nsp.csc.CWSServer. Right-click "nsp.csc.CWSServer" and choose Properties. Under Level, change from "Information" to "Trace", then click ok. Let it run a few minutes. If there are some user input needed to recreate the Smart Connector issue, then perform these steps now. Retrieve the log by right-clicking [AS/ES name]/System/Modules/Trace/TraceSettings and choose Trace settings->Get trace log.  Save the log file. Once debugging is complete remember to change log level back to "Information" (reverse of step 3). Note: If the ES or AS is reset, i.e. cold started or warm started, the log level will return to 'Information', so if further increased logging is required, the procedure will need to be repeated. Note2: This option is only availabe for EBO version 6.02 and onwards

Issue For various reasons, sometimes it is necessary to move a previously configured Infinet i2 device from one Infinet network to another in the same parent Automation Server, EcoStruxure Building Operation does not provide an automatic way to move an i2 device; it must be done manually. Product Line  EcoStruxure Building Operation Environment Building Operation Automation Server Cause Guidance on steps to move Infinet i2 device from one Infinet network to another in the same host Automation Server Resolution In this example, we are going to move multiple Infinet i2 devices from the Infinet network on COM-A to the Infinet network on COM-B.   Backup Make sure to make a backup of the Automation Server before attempting the steps below. This is in case there is a need to revert the changes for whatever reasons. Export Devices from COM-A From COM-A Infinet network, display a List View of the devices, making sure to have columns displaying the Infinet ID and Serial Number. Write down the Infinet IDs and Serial Numbers of the devices to be moved. In the List View, multi-select the devices to be moved, right click and perform an 'Export', leave the Export Reference Filter at default (Export). After successful export, right click on the selected devices again and delete them from COM-A Infinet network. Prepare COM-B for Import From COM-B Infinet network, display a List View of the devices, making sure to have columns for Infinet ID and Serial Number. Observe the Infinet ID column, and compare with the notes taken above of the moving devices' Infinet ID, for IDs that are already in use in COM-B, you will need to assign a new ID to the device moving from COM-A Infinet network to COM-B, update your notes to include an available ID on COM-B. (see example below of what the notes might look like)   Import Devices to COM-B In the System Tree, select the COM-B Infinet network and perform an import of the XML file created via export above. Physically move the devices from COM-A Infinet to COM-B Infinet. When doing so, avoid introducing duplicated Infinet IDs into COM-B Infinet. Make sure to power down the devices you are moving, connect them to COM-B Infinet, and only then power up the devices. On power up, the devices perform an ID check and stay off the bus if they detect their IDs are already in use. Configure Devices in COM-B From COM-B Infinet network, display a List View of the devices making sure to have columns for Infinet ID and Serial Number. Right click each device moved from COM-A Infinet to COM-B Infinet, and select "Properties", in the "Advanced" tab, enter the appropriate Infinet ID and Serial Number for the device then click "OK". In the List View, right click the device from previous step again, select "Device->Commission", after successful commission the device should go ONLINE Final Steps After all the moved devices are online, you should download ALL (whether moved or not) the devices to have their programs recompile and rebuild their Import/Export tables. Fix any references that were lost due to devices changing Infinet network and Infinet ID  

Warning Hazard of Electric Shock: Remove all power from all devices before removing any covers or doors of the system. Disconnect power at the device and at the power source. Electrostatic Discharge Required: Always discharge static electricity from your person by touching metal prior to handling any hardware. Failure to do so may result in damage to devices. Issue Why is it recommended to not mix high and low voltage connections on the same side of an CRS-HH-REL-10? Product Line EcoStruxure Building Operation. Environment Building Operation Room Controller (RPC) 24 V Building Operation Room Controller (RPC) 230 V Cause According to the documentation, it is not recommended to mix high and low voltage connections on the same side of the device.   Resolution There must be a minimum distance between terminals connected to High Voltage and terminals connected to Low Voltage of at least 5.5 mm to prevent the chance of voltage creep between the terminals.

Issue One of the following error messages are displayed. Internal server error Server already part of a system Product Line EcoStruxure Building Operation Environment Building Operation WorkStation Building Operation Server Cause Version Mismatch: The Automation Server is either not the same version as the Enterprise Server or it is still connected to a different Enterprise Server. If the Automation Server is still connected to another Enterprise Server then it must be detached before it can be added underneath a new Enterprise Server. User Permissions: In some instances, the User Permissions "System Address" is not added to the user account that is attempting to add the server.    Resolution If you are given an error that states "Domain: Internal Server Error" then you need to download the same version of firmware to the AS that is installed on the ES. Resolution #1: Detach the Automation Server Log in to the Automation Server.   In the system tree pane, right-click on the automation server and go to Advanced > Detach server.   The Disconnect Automation Server window will open; click yes.   The Automation Server is now detached and can be added to an Enterprise Server. Resolution #2: Verify User Permissions Check a current backup using the SBO xbk Analyzer and verify the number of servers listed under Reports>Servers Log on using the default admin account and see if these servers exist. Detach the server(s), as described above. If the secondary user still requires permission to add and see ALL servers: Go to the user and select the Permissions tab Ensure the ES path is selected Click on the Add System button (identified with the arrow) Enable all options to allow read/write, create etc.  Save these changes and log off and back on with this user to see the changes. This user should now be able to add/see ALL servers.

Issue What temperature limit should the CPU Temperature stay within? Product Line EcoStruxure Building Operation. Environment Building Operation Automation Server Premium Building Operation Automation Server Bundled Cause From EBO version 3.2, the CPU Temperature is added. Resolution The CPU temperature parameter displayed in the UI property dialog Automation Server Properties – Basic Tab is intended for internal debugging purposes only. Users are not required to monitor or take action based on this value, as there is no specified maximum CPU temperature level that requires user intervention or indicates potential CPU performance degradation.  

Issue The instance values the Function Block program had when the backup was taken is lost when the backup is restored in an AS-P running in PCT. Product Line EcoStruxure Building Operation Environment Building Operation Project Configuration Tool (PCT) Cause When the program is first initiated, the values for it is written to the database. If the “Program executions” Is turned off, the instance values the program had when the backup was taken is not read. Hence the values are set to 0.   On a real AS-P, a Cold start is performed after the restoring of the backup. When restoring a backup on an AS-P in PCT, one or two cold starts are done, followed by an additional warm start at least for the PCT 2. Resolution To get the instance values from the backup when it is restored, the “Program execution”/”Enable program” In PCT should be turned on before the restore is done.   Since a warm start is done for the PCT, the issue regarding Retain level vs. FB Backup property needs to be taken into consideration. https://ecostruxure-building-help.se.com/bms/Topics/show.castle?id=15741&locale=sv-SE&productversion=7.0&a=1

Issue Even though the curve block is set to range between 0-100, the block just stays at a fixed output somewhere in the curve output range. Product Line TAC Vista Environment Vista Workstation Cause The curve requires the first entry of the X value to be the lowest value, and then the subsequent values to be larger than the previous X entry. Resolution Adjust the order of the XY entries on the curve block so the first entry in the X will be the lowest value. Example of Incorrect Curve Here is an example of a Curve that will not work. Note the first X entry is -2 and the last X entry is -6.  Example of Correct Curve To correct this curve, -6 is the lower number, so this should be the first X entry. Here is an example of the curve that has the correct X entry order

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.

Issue Alarms with an invalid Source path cannot be removed from ES or AS Product Line EcoStruxure Building Operation Environment Building Operation Workstation Building Operation 3.0 and higher Cause The invalid path prevents alarms from being deleted. In earlier releases of EBO, there was an issue whereby an error could occur in the source path of an alarm if the Automation Server was renamed. Most invalid alarms observed originate from this type of error. Resolution Use Alarms Integrity Check in the following steps.  Automation Servers first, then Enterprise Server, and finally, if installed, Enterprise Central last. See Alarm Cannot be Acknowledged Due to Invalid Paths for additional details.   Expand System, Right-click the Alarm Control Panel,  Choose Advanced - Alarms Integrity Check.   The command runs quickly. There is no confirmation that the check has run, but a review of the alarms will show that the invalid alarms have been removed.

Issue Enabling Scattered read for Modbus device that doesn't support it can lead to poll fail, with Point Modbus Error: Illegal function code. Product Line EcoStruxure Building Operation Environment Building Operation Workstation (1.5 and above) Building Operation Automation Server Building Operation Automation Server Premium Building Operation Automation Server Bundled Building Operation Edge Server - Standard Building Operation Enterprise Server Cause Requirement to optimize communication over Modbus to improve performance. Resolution The following is an extract from Web Help. The complete section can be viewed at  Modbus Batch Read Function:   'Scattered read is an enhancement to the batch read function that enables multiple, non-contiguous slave device registers to be read in a single Modbus query. By using the scattered read function, you can enable the Enterprise Server or Automation Server to avoid reading a large block of contiguous registers when it is only necessary to read a few registers. Also, using scattered read avoids the multiple use of group function codes 03 (analog output holding registers) and 04 (analog input registers) in order to read non-contiguous registers. Group function codes 01 (discrete output logic coils) and 02 (discrete input contacts) are not supported for scattered read.   Scattered read is available only for supported devices, for example, Schneider Electric branch circuit power meters with split core CTs. Furthermore, the scattered read function applies only when the Enterprise Server or Automation Server is operating as the client, not as a server. You can enable the scattered read function in the properties of all Modbus devices. If a device does not support scattered read: In V6 or higher: the polls will fail with an Illegal function code, so scattered read needs to be disabled if not supported by the Modbus device. In V5 or below: the device is polled by the master device in the same way as if you had not enabled scattered read.'   The image below shows the properties dialogue window for a Modbus device and the corresponding setting.  The left is version 3.1 and above, the right is version 3.0 and below where it is referred to as 'Non-contiguous read'.  Refer to the Modbus TCP Device  section on Web Help for more information.     

Issue Why do the Architectural Guidelines specify a maximum of 1500 Extended Trend Logs in Automation Servers, whereas such a limitation did not exist with the Continuum Net Controllers, like the NetController II.   Product Line EcoStruxure Building Operation Environment Building Operation Automation Server Premium Building Operation Automation Server Bundled Cause EcoStruxure Building Operation's architectural guidelines specify a limit of 1500 Extended Trend Logs for the Automation Servers (AS-P/AS-B). Sites transitioning from Andover Continuum to EcoStruxure Building Operation need to understand the architectural differences that necessitate this limit. Resolution The architectural differences between Continuum and EcoStruxure Building Operation means that it is crucial that Extended Trend Logs are managed effectively to ensure ensuring optimal system performance.   In Continuum: Controller Role: Controllers do not participate in Extended Trend Log functionality beyond sending data from intrinsic logs upon request from Cyberstations. Log Management: Extended Trend Logs reside at and are managed by Cyberstations. Load Distribution: Multiple Cyberstations, configured to collaborate, maintain the Extended Trend Logs, minimizing the load on controllers.     This design puts very little load on the controllers when it comes to Extended Trend Log functionality.   In EcoStruxure Building Operation: Distributed Database Architecture: Extended Trend Logs are managed by the AS-P/AS-B servers. Server Load: The server performs tasks typically handled by multiple Cyberstations in Continuum, which often run on more powerful PC hardware. Performance Management: To prevent Extended Trend Log servicing from overwhelming the Automation Server's resources (CPU, memory), a limit of 1500 logs is enforced. Exceeding this limit can degrade server performance and potentially cause reboots due to critical memory usage.  This can be seen in the following example trace log entry: Nov 30 15:39:58 PSS-AS02 memcritsv[1011]: Memory usage critical!

Issue EcoStruxure Building Operation allows using a period embedded in the name of an object (i.e My.AnalogValue) and  the name of a binding variable in the Script program cannot contain a period.     In the Script program all the periods in the binding variable names have to be changed to a different character such as the underscore (_).   This in turn causes a problem for a programmer that has created many objects using the period in the names as it is now NOT possible to use the default name matching binding template. Product Line EcoStruxure Building Operation Environment Script Programs Enterprise Server Automation Server Cause Script programs do not allow a period '.' in binding variable names because the period has special functionality in the Script compiler. Resolution Create a new path matching binding template or edit an existing one to map the underscore to the period.     Here is a second example:   Name of point/value contains embedded '.' as well as spaces      This is what the binding variable would look like in the Script program   and here is the Path Matching Template

Issue The EBO license is activated on a virtual machine, need to make sure that it will not get damaged. Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Server Building Operation Enterprise Central Building Operation Workstation Cause Scenarios leading to broken Trusted Storage (license damage), when license is activated on a Virtual Machine. In some cases, the License Administrator can be used to repair the license, and in other cases, product supported will need to be contacted. Resolution FlexNet documentation explains how licensing in virtual machines works, what causes license damage, and how to avoid license damage. Make sure that documentation is related to the FNP version (FlexNet publisher) used by installed EBO, ex. EBO V4.0.2 uses version 2021 (11.18.1) and EBO V5.0.2 uses FNP V2022 R3 (11.19.2).  You can also check the FNP version by checking the properties, details of lmadmin.exe file located in C:\Program Files (x86)\Schneider Electric EcoStruxure\Building Operation x.x\License Server Binding elements for licenses activated on a virtual machine: FlexNet publisher documentation lists three binding elements for virtual machines, all of which are deal breakers: MAC address, UUID, and Generation ID, refer to Binding in a Virtual Environment (revenera.com)  Scenarios that can cause license damage (Trusted-Storage Breakage): In the attached FlexNet White Paper: Understanding Virtualization Features in FlexNet Publisher, Page 9, details binding variables and which scenarios can change each binding element.

Issue How can EcoStruxure BMS server serve data to external devices or software? Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Server Building Operation Enterprise Central Building Operation Automation Server Building Operation Automation Server Premium Building Operation Automation Server Bundled Building Operation Edge Server - Standard Third party devices or software Cause The EcoStruxure Building Operation software supports the major communication protocols in building automation and security management. In many projects, it is required that an EcoStruxure BMS server serve data to external devices or software, E.X. HMI, SCADA or power monitoring. Resolution The following is a summary of the available options to serve EcoStruxure BMS server data to the external world: BACnet:  When you create a BACnet Interface, the system automatically creates the Application and IP network folders within the BACnet Interface folder on the System Tree. If you create a BACnet Interface for a SmartX server, you can optionally create an MS/TP network. You can create BACnet objects in BACnet application folder of EcoStruxure BMS servers and these object will be visible for external BACnet clients. More information about EBO BACnet interface: BACnet Interface   Modbus Slave network:  If you configure the Modbus Slave Network (and associate it with a serial port), you can set up any external Modbus master device to communicate with the internal Modbus Interface. In this example, a Modbus Slave Network is set up on an EcoStruxure BMS Server and the external master device is configured with the same Modbus properties as the Modbus Slave Network object. The Modbus master device can also be an HMI device. More information about Modbus serial interface: Modbus Serial Networks Modbus server network: You can create a Modbus TCP Network on an Ethernet network (TCP/IP).  You can create an internal interface which acts as the server to an external client/clients. More information about Modbus TCP interface: Client and Server Networks   MQTT: MQTT is a lightweight and flexible data transfer protocol for IoT resources. EcoStruxure Building Operation, V3.2 or higher, can be configured to send data to an MQTT broker on interval or event-driven. The below are the tested brokers: Microsoft Azure IoT Hub Amazon IoT Core IBM Watson IoT Mosquitto More information about MQTT interface: MQTT Overview LonWorks Interface: EcoStruxure BMS servers can have a local node on their networks that can act as a LonWorks node. In the local node, you can create your own NVs that can be bound to external LonWorks devices using LonWorks bindings. The NVs in your local node can then be used in EcoStruxure Building Operation bindings for applications and graphics. More information about LonWorks interface: LonWorks Engineering   SNMP: Simple Network Management Protocol (SNMP) is an Internet-standard protocol for managing devices on IP networks. The EcoStruxure BMS servers support SNMP version 3. The SmartX servers support several SNMP traps. SNMP traps enable an agent to notify the management station of significant events by way of an unsolicited SNMP message. More information about SNMP: SNMP EcoStruxure Web Service (EWS) server: EcoStruxure Web Services allows seamless sharing of operational data, including alarms and historical information, between software from different Schneider Electric Business Units. When the EcoStruxure BMS server is an EcoStruxure Web Service server, it exposes objects, such as values, to another EcoStruxure system that is an EcoStruxure Web Service client. The EcoStruxure Web Service client can read and change values on the EcoStruxure BMS depending on the configuration of the EcoStruxure BMS server.

Issue EBO server has receive timeout parameter for Modbus TCP gateway, and the gateways has also time for the serial line. Having both timeouts not configured properly can lead to instability issues. Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Server Building Operation Automation Server Premium Building Operation Automation Server Bundled Building Operation Edge Server - Standard Cause When EBO sends a request to the Modbus gateway, e.g. polling a register from a serial device, it expects the gateway to respond with a value or exception code within the configured receive timeout. The Gateway will forward the request to the serial device and wait for a response within the timeout configured in the gateway.  If the device fails to respond within the timeout period, the gateway will send an Exception code 11 to EBO (Gateway Target Device Failed to Respond).    If the timeout configured in the EBO server is less than or equal to the timeout configure in the gateway, the EBO connection to the gateway may timeout before the connection between the gateway and the Modbus device timeouts.  This can lead to frequent device offline alarms, if one or more devices are slow or offline. Resolution The receive timeout configure in the Modbus TCP Gateway Properties – Basic Tab should be higher than the serial line timeout configured in the Modbus TCP gateway. Please see Setting Message Timeout for Modbus Client and Modbus Server - EcoStruxure Panel Server User Guide for examples/recommendations.

Issue Timestamps in Script programs are different by an amount equal to the UTC offset of the workstation's timezone settings. Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Central Building Operation Enterprise Server Building Operation Automation Server Premium Building Operation Automation Server Bundled Building Operation Edge Server - Standard Building Operation WorkStation Script editor Cause Take the following program as an example:   Datetime Output TimeOut, TimeOut2 TimeOut = StrToDate ("1/17/2012 15:00") TimeOut2 = StrToDate ("1/17/2012 3:00 PM") In EcoStruxure Building Operation, the values will read:  "1/17/2012 9:00:00 AM" (in this example, the UTC offset is set for -6). In servers, all time values are stored in UTC, then the offset is applied by the client.  When it receives a value from a Script program, it stores the value as UTC, then the offset for the selected timezone is applied. Resolution Write code in the Script program to adjust the time values to UTC. Check the example code below to help understand operation: Datetime Output dtOut1 Datetime Output dtOut2 String Output str1 dtOut1 = Date 'Local time, displays with added UTCOffset dtOut2 = Date - UTCOffset - DST 'Local time, adjusted by the UTCOffset and DST, displays properly Print Date to str1 'Local time String value displays properly (UTCOffset system variable is available in v2.0 or higher, DST system variable is available in EBO 2022 v4.0 or higher)
