Issue Confusion in documentation of the output type of an STR300 temperatire transmitter Product Line Field Devices Environment STR300 series transmitter Cause The STR300 is an electronic living space transmitter that converts a measured temperature into an electric current signal. The transmitter is delivered as a complete unit, comprising a Pt100 classB sensing element and an amplifier mounted in a housing. STR300 is intended either for surface mounting on a wall or installation in a standard switch box in dry, dust free rooms.   The HVAC Sensors Catalogue incorrectly shows that the STR300 Series has an Output of 0-10V while  the datasheet correctly shows the output as 4-20ma. Resolution The STR300 has an output signal of 4 to 20 mA corresponding to a temperature range of 0-40°C

Issue Are the Infilink and B-Link interchangeable or can they be converted? Product Line Andover Continuum, EcoStruxure Building Operation Environment Infilink 200 B-Link Cause Both units are RS-485 repeaters; is there a difference? Resolution You cannot convert from an Infilink 200 to a B-Link. They are both RS-485 repeaters, but the circuitry is slightly different to handle the electrical requirements of the BACnet MS/TP and the Infinet. You must use the correct unit for the network type you have. The multiple ports on both repeaters (Infilink and B-Link) allow you to construct a star topology configuration, but note that devices in each spoke (port on the repeater) MUST be connected in a daisy chain topology. Neither product contains any firmware that can be changed.

Issue Notifications (email or text file) are sent when an alarm is enabled by the shunt variable Environment Notifications Cause The Alarm object has 6 possible states that it can take   Normal - Idle state where the alarm monitors the variable. Alarm - When an alarm is triggered, the state of the alarm changes from the normal state to alarm state. Disabled - You can disable an alarm when the alarm is triggered by faulty reasons, the alarm toggles between the alarm state and reset state, or maintenance will trigger the alarm. A Disabled alarm can be hidden in the Alarms pane or Alarm Views. To reset the alarm, you have to show hidden alarms and then enable it. When you show disabled alarms, enabled alarms are hidden. Alarms are also disabled by using the Shunt Variable in the alarm configuration. Reset - The monitored variable has returned to a value that is within the normal condition of the alarm, but the alarm has to be acknowledged by a user before the alarm returns to normal state. Acknowledged - A user or user group has acknowledged the alarm. Fault - If a BACnet device reports values that it knows are not trustworthy, the monitoring alarm is put in fault state. The notification is triggered by transitioning to any of these states as selected in the "Notify on transition to" portion of the notification configuration This means that if you wish to receive a notification on transition to the Normal state, you can check the Normal box. However, this means that not only are notified when the alarm transitions from Alarm to Normal, but from Disabled to Normal or Fault to Normal.  Some of the scenarios may be undesirable. Resolution There are two ways an alarm can go to Normal: Alarm to normal Disable to normal In the Email notification main filter, you can choose to not get a notification from disarm but you might want to get a email about normal since you want to get a email when an alarm goes to normal. To accomplish this you need to add another filter called "Previous alarm state." (This filter does not work in releases prior to 1.3 SP1.) To add the filter Previous Alarm State: Click on the green + Check the boxes you want: Acknowledge Alarm Normal Reset Make sure Disable is not checked This means that when the previous state was disabled (shunted), a notification will not be sent.   Example1: This object will always trigger a notification on Alarm.  The notification will be triggered regardless of Previous State. If the Alarm is Disabled by a shunt, then enabled, but the Monitored Variable is still out of Range, a notification will be sent.   Example2: This object will only trigger a notification on the Transitions from Alarm to Reset, Alarm to Normal, Acknowledged to Reset or Acknowledged to Normal. This might be desirable for a user that wished to know when an object in Alarm returns to normal operation, but not know when an alarm goes from Disabled to normal operation.

Issue How to estimate the disk space required to accommodate a given Security Expert installation. Product Line EcoStruxure Security Expert Environment Security Expert Microsoft SQL Server Cause The Security Expert databases will grow in size depending on the configuration and logging requirements. Therefore, estimating how much a database will grow over time should be done to determine which Microsoft Database solution and hard drive requirements. Resolution The Installation Guide does have some hardware recommendations under the System Requirements section, and these should be used as a baseline for allowing appropriate database storage. 10 controllers w/ 16 modules each - 40GB More than 10 controllers w/ any number of modules each - 100GB. The configuration database (SecurityExpert) is relatively small and will typically not grow much. The events database (SecurityExpertEvents) is what logs all events and alarms, and it will grow over time, rapidly depending on what is being logged and how often. There are many variables in play from one site to another. The space required for a standard Security Expert Database is dependent on, but not exclusive to: The amount of Inputs/Outputs/Readers you have with Log Events enabled. The amount of traffic through the site. The number of Expanders and other Records. The frequency of backups and purging of events from the SecurityExpertEvents database. As a guideline, we can broadly calculate storage requirements based on the size of each event being logged. Typically this will be 564 bytes per event. If you have 2000 Events per day, here is the calculation for how many MB will be used per day: 564 B x 2000 = 1128000 B = 1.07 MB per day If those events that are being logged are alarms as well, then this total would be doubled. Another way to calculate this is to take what a typical usage requirement would be for a site or monitor a live site over a week/month to calculate the sites' average usage and extrapolate that to fit. For example, a site with 130 doors being used 8 hours a day and with door openings and closings 10 times an hour would equate to just under 1GB a month. Please note these are very rough guesses; individual sites might be busier/quieter. Performing regular SecurityExpertEvents database backups and purges will ensure that the database size does not get too large for the installation. For instructions, see the System Backups section in the Installation Guide and AN 279 Security Expert Differential Backups.

Issue Email alarms can be configured in the AS and ES and understanding that interaction is needed Environment SmartStruxure Windows 7 Windows Server 2008 Cause There is a need to know what happens when creating email alarms in the AS and ES Resolution The server (AS or ES) that has the email notification object will send the email. So if you want to be sure that the AS alarms still send emails even if the ES is offline, then you should have email notifications configured on the AS and not rely on a global email notification on the ES. If notifications are configured on both the ES and AS which triggers on the same alarm, then two emails will be sent. One when its triggered on the AS and one when the ES fetches the alarm from the AS. You may be able to manage the triggering of the AS alarm by a program that checks the online status or alarm indication of the ES being offline.

Issue When launching Security Expert after restarting the PC, a License Expired message is shown. The license is not able to be found. Product Line Security Expert Environment Security Expert Client Security Expert Licensing Cause This is a timing issue. The Security Expert services are attempting to start simultaneously as Windows components that they rely on. Resolution Change the Startup Type of the Security Expert services to use Automatic (Delayed Start), so they start after the Windows OS components. Services - Automatic Delayed   It is also possible that the Security Expert Data Service may be the only service that requires being set to a delayed startup to resolve this problem.

Issue Security Expert Smart Connector integration is working but Alarms states are not updating, the following error is appearing in Smart Connector logs:   2021-01-07 15:19:22.2621,Info,Processor,<no principal>,Validation Prompt for Security Expert Alarm Update Processor: MayNotContinue : The EwsServer was not located or the credentials you supplied were incorrect. Please verify your credentials and try again. Product Line EcoStruxure Security Expert Environment Smart Connector Cause It appears that the SOAP credential within the Security Expert Discovery Processor does not match the credential within the Security Expert Client SOAP operator credential.   This is a known issue where the credential does not update when changed/edited within the Processor Configuration of the Security Expert Discovery Processor configuration.   Resolution A workaround is to log on to your local Smart Connector portal and edit the credential value within: Setup/Processor Values/SecurityExpertSettings      Change the username and password as required here.                Then save and the new credentials should be updated.  

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 When EcoStruxure Building Operation (EBO) is installed after TAC Vista on the same PC, changes to the national character set in the OP Configuration Tool in Menta cause an error preventing the generation of the MTA file. The error appears when the Generate command is selected in Menta. Depending on the combination of versions of EBO and TAC Vista, the error message is: "National character set not selected" "Cannot open file: struxureware path\ national.dec" (where struxureware path is the location of the Schneider Electric StruxureWare\ Building Operation 1.x installation folder) "ERROR! Failed to create OLE dispatcher: GraphOP.Application.320, GraphOP.Application.NSP" Product Line TAC Vista, EcoStruxure Building Operation   Environment Building Operation Workstation Vista Workstation Cause The installation of EBO overwrites settings in Menta regarding character sets. When Menta is opened with normal user rights, changes to character sets in the OP Configuration Tool are not saved due to the OS user security settings. Resolution Right-click on Menta in the program list and select "run as administrator". Then select your required character set in the OP Configuration Tool ("Formats | Character set file"). The changes can now be saved and Menta will generate successfully. This procedure is only required the first time you run Menta after installing EcoStruxure Building Operation. Normal user rights can be used for subsequent editing sessions.

Issue What is the unit load (UL) of the SpaceLogic SP90 PIBCV Actuators that will help me to calculate how many SP90 PIBCV Actuators can be added on ComA and ComB of a SmartX Server. Product Line EcoStruxure Building Operation, Field Devices Environment SpaceLogic SP90 PIBCV Actuator SmartX Server Cause Require the Unit Load (UL) of the SpaceLogic SP90 PIBCV Actuator to calculate the number of actuators allowed on the RS-485 network.  Resolution The Generic application note AN01 can be applied with answers to the transceiver interface attributes below. The SpaceLogic SP90 PIBCV Actuator range uses the SN65HVD1780DR transceivers which are a failsafe transceiver (not requiring bias) and reduced 1/10 UL. In addition, there are no local bias resistors and therefore the 1/10 UL of the transceiver would be the total UL presented to the bus by the SpaceLogic SLP Room Unit. Transceiver Xcvr Unit Load Xcvr Failsafe Adaptor Circuit Bias Circuit Bias Load Total Unit Load Isolated 485 Bus SN65HVD1780DR 0.1 Yes None None 0.1 No Based on the above the total number of devices can be calculated as 32/0.1 = 320. The BACnet MSTP standard specifies that the address range for BACnet master devices is 0-127 and therefore a SmartX Server is limited to 127 devices per com port (254 total per Server) so this should effectively be the limiting factor. However, the documentation recommends using only up to 64 devices with the same RS-485 transceiver, or 32 devices with different RS-485 transceivers.   Since the SpaceLogic SP90 PIBCV Actuator does not have an isolated RS-485 interface it conforms to Generic RS-485 Network Device Configuration 1 in EBO Webhelp.  A network consisting of only SpaceLogic SP90 PIBCV Actuators should only require a 120-ohm termination resistor at each end of the bus and not require any bias resistors. Also, check out the SmartStruxure-RS485-Controller Unit Load Quick-Help video on the Exchange.

Issue Why are there Unconfigured Devices appearing in the Unconfigured Device list. Unconfigured Devices are not cleared from the device list once the third party device is correctly configured and brought online. Product Line EcoStruxure Building Operation Environment Building Operation Automation Server Premium Building Operation Enterprise Server Unconfigured BACnet Devices Cause BACnet devices that have unresolved issues appear in the Unconfigured Devices folder beneath the Hardware folder. The devices in the folder may have one or more of the following unresolved issues: • Unspecified device identifiers • Duplicate device identifiers • Duplicate device names • Other interoperability issues These issues must be resolved at the third party controller end. Resolution There are 3 different ways to resolve this depending on AS-P version: 1.9.x: To clear the reconfigured devices from the Unconfigured Devices folder, select the network, and then press the Alt key and click the Refresh button at the same time. 2.0.x or later: For updates use the Discover All (binoculars) button Any version after the third party devices have be correctly configured and brought online, if any devices these device continue to appear in the Unconfigured Device list they can be cleared from the list by warm starting the AS.

Issue When a modbus AO is created and set to 32-bit real swapped, the correct value is not seen at the modbus device. 1000 is written and 1000 is shown correctly at the Modbus device. 1001, 1002, 1003 are written but 1000 is seen at the Modbus device. 1004 is written and 1004 shows correctly at the Modbus device. And so forth. The larger the number, the larger the error increase. Product Line EcoStruxure Building Operation Environment Enterprise Server (ES) Automation Server (AS) Cause When 32 bit real swapped is selected Further down the configuration page, the write function code defaults to "06". 06 is to set a single 16-bit register write and this needs to be changed. Resolution Use the drop down tab and set the function code to "16". 16 is to preset multiple registers i.e. 2 off consecutive 16-bit registers or a 32-bit register.

Issue Checking if a port is open Product Line Andover Continuum, EcoStruxure Building Expert, EcoStruxure Building Operation, Field Devices, Pelco, Satchwell MicroNet, Satchwell Sigma, TAC IA Series, TAC INET, TAC Vista Environment TCP/IP Communication Command Prompt Telnet Command Cause Suspect certain network ports are blocked and need to verify Resolution It is possible to check if a port is open in a network by issuing the Telnet command. Note:- Telnet operates using the TCP protocol. UDP connectivity cannot be tested using Telnet. If a port is open, a blank screen will be seen after issuing the command: telnet [domainname or ip] [port] where [domainname or ip] is the domain name or IP address of the server being checked [port] is the port number the server application is listening on For example: telnet 192.168.0.20 9001 (to a closed port would display a connect failed message)   telnet 192.168.0.20 9003 (to an open port would display a blank screen)   To exit the Telnet session, type Ctrl + ] and then type "quit".   For how to enable Telnet in Windows 7 please see Enable Telnet Client on a Windows 7 PC

Issue How to populate customized information on the SpaceLogic Sensor display Product Line EcoStruxure Building Operation Environment SpaceLogic Living Space Sensor Building Operation Multi-purpose Controller Building Operation Multi-purpose VAV Building Operation Room Controller (RPC) Building Operation Workstation Cause Additional information required on how to customize information to be displayed on the SpaceLogic sensor Resolution Note: This feature may not work in controller FW V4.00.x, due to know issue Custom value text is not displayed and/or updated on the SmartX sensor device, in this case please upgrade controller firmware to V5.00.1 or higher. Before starting, make sure the Integrator Menu icon and the custom information page have been activated: The Integrator Menu icon can be configured under "SmartX Sensor Device/ Display/ Button and Scene configuration" as shown in the screenshot below: Turn on "Allow custom information page" under "SmartX Sensor Device/ Display /Advanced" tab. By doing this, the custom information page is created under the Integrator menu icon of SmartX Sensor Display:        To show how to add custom information to the custom information page of SmartX Sensor display, create a sample script program, where DI1 is a digital input and Status1 is a string output. numeric input DI1 String output Status1 If DI1 = on then Status1="running" Else Status1="not running"​   In this program, when DI1 is on, the Status1 gets the string value of “Running”, otherwise the Status1 gets the string value of “Not Running”. DI1 is bound to a Digital Value (Green Arrows) under the Application folder and Status1 is bound to the CustomValueText1 (Red Arrows) as shown below:   Open the Watch pane, under the View tab, and add Digital Value and CustomValueText1 (access it through the “SmartX Sensor Device/ Display/ Basic” tab) to it.  When the Digital Value is Active the Custom value text 1 shows “Running”. On the SmartX Sensor, navigate to the custom page through the Integrator menu icon, this will show the “Running” string. Likewise the “Not Running” string would be populated on the SmartX Sensor custom information page screen when the Digital Value is Inactive.
