Issue The value of an exported Infinet point is not updated in some or all of the subscribing controllers. Product Line EcoStruxure Building Operation, Andover Continuum Environment Building Operation Automation Server Continuum i2 Controller Cause The subscribing controller is offline or inaccessible when the IE update is broadcast. Resolution The main disadvantage with the Continuum Import/Export (IE) system is that, in certain cases, it is possible that the updated value may not reach one or more of the subscribers due to various reasons such as network or controller down problems, excessive traffic on the network, etc. This is not of big concern when the point is of an analog type that changes frequently such as a temperature input since the point will update again when the temperature changes in a matter of seconds or minutes at the most.  For binary values though, a missing update is a big concern. Consider an occupancy schedule point that turns ON at 08:00 and off at 17:00.  If a subscriber misses the 08:00 update the zones under control by the subscriber will be unoccupied the entire day. The Point’s Refresh Attribute. Continuum points have a ‘Refresh’ attribute that is used to force the IE system to send a new updated value, setting the refresh attribute to true forces the Infinity controller to export the point’s value regardless of whether it has changed or not. It is IMPERATIVE that a PE program periodically refreshes binary points that are exported in Infinity controllers such as i2 devices. In the schedule example described above, a program* can be added to the Infinet controller that hosts the exported point.  This program should be triggered by the minute system variable and coded as follows: *make sure the program is of the type Infinet Script Program This will ensure that any subscribers to the schedule OCC flag won’t go more than a minute with a stale value of the point. Refreshing points that reside under the Infinet interface of the Automation Server (EBO 3.1 and greater) If the point to be refreshed resides under the Infinet interface of the AS-P then there are some differences in the way the refresh is accomplished. The program will be of the type Script Program. The point will have a REFRESH property, you bind to the refresh property in the Script Program instead of the point's value. The most important difference is that while in the i2 device the export takes places when you set the value of the refresh property to true, in the Automation Server the export takes place when the value of the refresh flag is toggled, regardless of the value (true or false) Below is an example of a Script Program refreshing some value objects that reside at the Automation Server under the Infinet interface The statement DigValue1 = (DigValue1 = false) is just a very efficient way to toggle the value of the refresh property, it is equivalent to saying.... If DigValue1 = false then set it to true and if DigValue1 = true then set it to false. Things to consider when refreshing exported points. Do not refresh points at a fast rate as this will cause unnecessary traffic on the Infinet field bus, refresh rates of one minute or more are strongly recommended. For the same reason, when refreshing many points, the operation should be staggered to avoid flooding the Infinet bus with an avalanche of IE traffic at the same instant.

Issue Need a method for mass importing User photos for creating / updating the Users for a Security Expert site. Product Line Security Expert Environment Security Expert Security Expert Data Sync Service (SX-DB-SYNC) Cause Data Sync Service is typically used to import data from the third party system.  In this instance, a CSV file containing the data to be imported into the Security Expert database is used. The Data Sync Service is configured to monitor the folder where this CSV file is located and automatically (if configured) import the relevant data into Security Expert, creating records (including users, access levels, areas, doors, schedules, and so on) for each matched entity. Resolution The Data Sync Service can be used to map specific fields from a CSV file to fields within Security Expert. One of those fields can be the User photos. Below is a guide on how to implement this.   1. Directory Setup Before opening the Security Expert Data Sync Service, it is necessary to setup a CSV file and directory for the Data Sync Service to work with. The only requirement for now is that each image must have a unique name and that the folder housing the images must be called "Photos". Figure 1 shows an example folder structure: Note: The names of the folder, CSV file and image names are not critical. As long as the image names match what is in the CSV file.   2. CSV File A CSV file is a comma separated file with each row being a separate record and columns (fields) separated by comma's. An example CSV is shown below:   UniqueID,FirstName,LastName,AccessLevel,PIN 101,First,User,Visitor,1284 102,Second,User,Visitor,5618 Note: The UniqueID field will need to be the file name of the Users image. For the below example CSV, two images must be present in /Photos/ with the names 101.jpg and 102.jpg.   3. Security Expert Operator It is recommended that a new Security Expert Operator is added for importing from the Data Sync Service. This ensures that records that have been added / modified / deleted by the Data Sync Service can easily be identified. To proceed past the Data Target section the Show PIN numbers for Users option must be enabled in the Operator object.   4. Data Target Now that an Operator, directory and CSV have been set up, open Security Expert Data Sync Service and follow these steps: Select Security Expert from the Target System dropdown. Confirm the SOAP Server Address. If the defaults were accepted during the installation of the SOAP Service, enter http://localhost:8030/SecurityExpertSOAPService/service.svc. Enter the Username of an Operator. Enter the Password for that Operator. From the Site dropdown, select the Site that the records are to be imported to. All Sites that have been added in Security Expert will be available in the dropdown. Overwrite the Site ID during the field mapping process if the records are imported to different Sites within a single import. Note: The rest of the fields on the Configuration window are disabled until a valid Server Address, Username and Password have been entered.   5. Sync Options Set the Resynchronize Every time to a time interval over which the service should resync data. Tick the Enable Error Log checkbox to populate the Event Viewer with events that will make error solving simpler.  6. Data Mapping  Configure the records and import file with the following steps. Select Users from the Record to Sync drop-down.  In the File Directory field, enter the created folder. If importing a single file, enter the name of the file in the Import File field. If the checkbox is left unticked, all files in the File Directory will be imported. From the File Format drop-down, select Delimited. If the import file is a CSV, select {CR}{LF} as the Row and {Comma} as Column delimiters. Enable the option to Start Import At Row 2 to skip the header.    7. Field Mapping The data mapping phase allows CSV columns (Source Column) to be mapped to a record type in the Security Expert Database (Target Field). To import the example CSV, the field mapping must be configured as below. Link a Target Field and Source Column, simply select both in the interface, complete the following: Link the following [Target Field : Source Column]: ImageID : 1, First Name : 2, Last Name : 3, UserAccessLevelGroupDataData > UserAccessLevel : 4 PINNumber : 5, Select ImageID (Column 1) as the Unique Field. For UserAccesLevel, open the Advanced Data Configuration by clicking the [ … ] button. Ensure that Use This Field As The Group Data Identifier is set and Grouping Type is Singular Data. Ensure Target Field Record Type is ticked and set to Access Levels. Click Save and then Start to begin the syncing of Users. 8. Troubleshooting If troubleshooting is required, examine the following logs: All Events - In Security Expert under Monitoring > Status Page View, open the All Events view to view Data Sync Service events. Event Viewer - Open the Windows Event Viewer and navigate to Event Viewer > Applications and Services Logs > Schneider Electric Security Expert event log.

Issue TC300 Series & accuracy Environment BMS Site Cause TC300 Series & accuracy Resolution The TC300Series-HotelApplication Stand-alone Digital FanCoil Thermostat specifications are as follows: There are two sensors possible for the unit. An embedded sensor is NTC100K, and for the external sensor as (below picture) it is NTC10K (3950). This chart defines the NTC Sensor accuracy (not the Control Accuracy which is in the specifications above):   The RS-03 10k NTC Remote Sensor-3m (Meters). Sites that want to extend further than the 3m, should know that the maximum length is 20m, we don't suggest more, but doesn't mean >20m have issues. The problem depends on the Electromagnetic Interference (EMI), Compatibility (EMC) in the field. Every site is different, and it is suggested to try in the field and see if it works fine. (When a remote sensor is connected (terminals S1 & S2) this remote sensor is automatically used. The internal sensor is ignored.) Note: TC300 thermostat supports Modbus RTU only. If you require LON, consider the SE7000 series controller. TC300 series replaces the DEGA 006905432 which is obsolete as of March 2004.  To control multiple fan coils with one ST300, a connection called the ST-2 is required. This expands the control up to 4 fan coils simultaneously but is not recommended since it may lead to uncomfortable temperatures in building area. For more info, visit The Exchange with search keywords TC300. The TC300 is only listed in the EMEA and AsiaPAC market. They are not UL approved.

Issue There is no indication that a card has been read when being presented at a Security Expert Smart Card Reader. Product Line EcoStruxure Security Expert Environment Security Expert Security Expert Smart Card Reader (SX-DRD-??, SX-DRK-??, SX-RD-??, SX-RK-??) Cause Reader is configured but there is no LED activity or beep when a card is presented at the reader. Resolution If the Security Expert Smart Card Reader does not blink or beep, then the reader cannot read the card for one of the following reasons. Wrong technology, e.g. trying to read a 125khz card on a 13.56mhz reader will not work and vice versa The card is encoded with a proprietary format/encryption The card is encrypted and the encryption keys are not programmed into the reader (note that this is different from the above case; there are many scenarios where cards are encrypted but not proprietary and therefore if the encryption keys are programmed into the reader it can be read) If you get a single beep/short flash of the reader ports reader LED but no event/data in Security Expert it means that the reader can read the card but the format at the reader port is not able to correctly interpret the data which is why no events are being logged. Another format should be selected from the Reader Format list to suit the card type, if no suitable format exists in the list a custom format must be created.

IIS and WorkPlace Pro (station database) have a conflict issue related to Port 80. By default, IIS connects and utilizes Port 80 when installed and running. This directly conflicts with an Enterprise Server’s station database running on the PC which also uses Port 80 by default. Resolution Most times, users do not require IIS on the Enterprise Server or WorkPlace Pro PC so IIS is disabled. If IIS is required, users typically change the port used by the station's database to another port (e.g. 8080, etc.). If this change is made, all other settings that access this IP for the station (address table entries, web browser pages, etc.) must append the port number to the IP address (e.g. 192.168.1.142:8080). Disable the IIS if not required by some other application on the Enterprise Server PC. Select Start and open the Control Panel Double-click add remove program Click on “Add/Remove Windows Components on left side on screen Scroll down and deselect Internet Information Services in the Components window Click next and Finish The Enterprise Server station can now be opened. Note:  On Windows 7 host computer, the World Wide Publishing Service may be linked to IIS.  Go to 'Services' in Windows 7 and modify its startup to 'Manual' so that it does not start automatically.  If IIS is needed on the Enterprise Server PC, then change the port used by the Enterprise Server. Open WorkPlace Pro Admin Tool and stop the Enterprise Server Open the Enterprise Server offline Right-click on the Enterprise Server station and open its Properties sheet Click on the Config tab Change httpPort to the desired port number and click Apply Right-click on the Enterprise Server and Save Close the Enterprise Server station Open Admin Tool and start the Enterprise Server station  Once the station starts you should now be able to access it. Please note that the port number must now be included in the station's address when accessing the Enterprise Server.

Issue Use of the Building Operation Script editor and general Script programming is covered in the Training courses and technical reference guide, what other techniques can be used to debug a program? Product Line EcoStruxure Building Operation Environment  Building Operation Script editor. Cause Often additional techniques are required to debug Script programs, especially when attempting to analyze, modify or fault find other people's code. Resolution Some techniques you can use for debugging your program and isolating problems are: Add in additional line labels to the program to isolate where the program is disabling or failing, if it disables you will be able to see the "CurrentLine" it has failed on and therefore know which line of code is causing the problem. Use the Trace feature to step through a program and monitor the binding variables, stepping through each line of code to ensure the values are all set as expected. Even if a program does not disable you can use the "Stop" keyword in the program, it will act as a break in the code and you can look at the values of the various variables, this may be a useful alternative to the Trace feature. Use the Watch window and the Binding Variables window to show the values of the various objects, when used with the above two techniques it allows you to accurately trace a program flow. Ensure all of the code used is compatible with the Script programming rules and that Continuum Plain English programs are not just used without conversion. Check the Plain English and Script Difference Guide. For programs in an i2 or b3 controller, ensure none of the Program size limitations are exceeded, see Plain English program limitations on number of characters in program and line labels.  

Issue Displaying Automation Server status on a graphic page Product Line EcoStruxure Building Operation Environment Building Operation Workstation Building Operation Webstation Automation Server Cause The online / offline status of an Automation Server can be viewed in the Workstation System Tree (Servers folder). However, there is currently no 'built in' method of displaying the Automation Server status on a graphic page.  Resolution There are two possible ways to workaround this   Within TGML Bind any Automation Server attribute that is shown only when the Automation Server is online (such as DateTime) and convert the status either by TGML script or a ConvertStatus element. See the attached example.   Using a script program We can create a point in the Automation Server and use another server to monitor this point. Below is an example of using the Enterprise Server to monitor an Automation Server.  Create a value point in the Automation Server. In this example, I have created an Analog Value point and set it to a value of 88.8. This value does not really matter but I have set to this value for easier recognition. Create a value point in the Automation Server. In this example, I have created an Analog Value point and set it to a value of 88.8. This value does not really matter but I have set to this value for easier recognition 1. Create a value point in the Automation Server. In this example, an Analog Value point (named 'Status')is created and set to a value of 88.8. The value set does not matter. It has been set to 88.8 for easy recognition.    2. In the Enterprise Server, create a new Program point (named 'Monitor AS' in this example) with the following codes.  Numeric Input In1 String Output Out1 Numeric Output Out2 Out2 = In1 If In1.Offline = true then Out1 = "Offline" else Out1 = "Online"   3. Edit the binding of the Script program and bind 'In1' to the Value Point that was created in the Automation Server.    4. When the Automation Server loses connectivity to the Enterprise Server, the Out1 output of the Script program will show 'Offline'. You can then bind this to a graphic page.

Issue When using the Modbus RTU X Driver to communicate to multiple Socomec Diris A20 electric meters it has been found only 2 or 3 devices can be networked together, even using a b-Link to boost the signal does not resolve the issue. Product Line Andover Continuum Environment Modbus RTU X Driver on bCX1 or Netcontroller II B-Link repeaters Cause The Socomec Diris A20 meters require a minimum of 4V RS-485 signal to communicate reliably, but the EIA RS-485 standard only calls for a +/- 1.5 volts signal and the Receiver Input sensitivity should be +/- 200mV. When using a bCX1 with the X Driver on Comm1 you will require a b-Link to provide the RS-232 to RS-485 conversion, although the B-Link fully conforms to the EIA RS-485 standard it does not have the drive levels required by the Socomec products. Resolution To resolve the non standard electrical requirement of the Socomec Diris meters use a Socomec RS-422/ RS-485 Repeater this will output the required electrical levels required by the Diris meters, the Socomec  part reference is 48990120.  Please refer to SOCOMEC Communication accessories or RS-422/485 Repeater Operating Instructions   If a B-Link is to be used each RS-485 output that is used will require a separate Socomec repeater.

Issue It is normal for a BACnet network port's Poll Service 'Busy Time' property to be greater than 100%? Eg: Product Line I/A Series Environment G3 BACnet Cause The Poll Service is a common component for typical field bus drivers including BACnet.  The Niagara Ax Drivers Guide defines the Poll Service's Busy Time property as: Displays a percentage of time spent by the poll thread actually polling points, across all poll buckets. Includes (in parentheses) a ratio of “(time spent polling/total time since statistics were restarted)”. Given a small amount of time is spent transitioning between poll buckets, and with the thread sleeping to evenly space out polling messages, it is unlikely to ever see Busy Time reach exactly 100%. However, any percentage above 95% indicates that the poll thread is basically spending all of its time actually polling.  Resolution In the case of the Poll Service for a BACnet network port, because two threads are used for polling, it is possible to see a Busy Time approaching 200%. In this case, divide the Busy Time in half to get an average busy time for each thread.

Issue Questions on the relationship between the area links in a personnel template and the links in derived personnel objects. Environment CyberStation Cause Documentation Resolution Q.  Personnel already has a Template assigned...What happens to the Area list when a different Template is assigned? Specifically, to the Areas already listed, will only the new Templates Areas be left or Is it a union or something else?  A. When the template is re-assigned the personnel objects will drop all areas that come from the template and pick up the areas from the new template. Areas that were assigned separately from the template (loose areas) will remain. Also, when changing the template the system will prompt you with several options to choose from for how to handle the attributes that are linked to the template.   Q. 2 Personnel has some Areas already assigned...What happens when that Personnel is assigned to a Template? A. Those areas that are not associated with a template (loose areas) will remain, the areas from the template are added to the person’s area list. Q. 3 Personnel has a Template already assigned...What happens when Areas are added individually? A. Those areas added individually (loose areas) are simply added to the person’s area list, template manipulation has no effect on loose areas.

Issue When attempting to login to Security Expert Web Client the below error is seen. The communication object, System.ServiceModel.Channels.ServiceChannel, cannot be used for communication because it is in the Faulted state. Product Line EcoStruxure Security Expert Environment Security Expert Web Client Cause The typical cause of this error is a mismatch in the security bindings between the SOAP Service and the Security Expert Data Service. For example if you enable the Windows Authentication checkbox in the Security Expert installer but not in the SOAP Service installer (or vice versa) then you have a mismatch. Resolution Either uninstall the SOAP service and update the checkbox selection to match whatever was selected in the Security Expert installer, or follow the instructions under Troubleshooting | Communication Fault/Failure in the SX-WEB - Security Expert - Security Expert Web Client - Installation Guide for editing the config files of the SOAP service to match the Security Expert Data Service.

Issue Step-by-step instructions for calibrating airflow on a Xenta 102-AX (or I/NET MR-VAV-AX) using the M/STAT. Test and air balance procedure for balancing airflow Product Line EcoStruxure Building Operation, TAC INET, TAC Vista Environment Xenta 102-AX MR-VAV-AX M/STAT Cause The preferred method for calibrating airflow in Xenta 102-AX or MR-VAV-AX is through the plug-in.  However, this is not always an option, especially when the responsibility for calibrating is given to a third party test and balance company.  Pocket references exist for navigating through the M/STAT menu, but there aren't clear step-by-step instructions to tell exactly how to perform the calibration. Resolution Click here to download this document in Microsoft Word format Connect M/STAT Plug the M/STAT into the jack on the thermostat. The initial display shows the set temperature.   Enter Password Press the Service button. This prompts you to enter the service mode password. Default password is 183.
