With the exception of their -V models and the bCX (bCX9640/bCX4040) controller, they were not designed to have their firmware swapped from Infinet to BACnet (or BACnet to Infinet) in the field. Product Line Andover Continuum, EcoStruxure Building Operation Environment Continuum i2 Controllers (except -V) Continuum b3 Controller (except -V) Cause With the exception of the -V controllers, the devices were not designed to have their protocol (Infinet/BACnet) swapped in the field, however, due to changes in market needs R&D is now providing a method to allow the protocol to be changed in the field. Resolution IMPORTANT: If a RoamIO2 is available, it can be used to do the conversion without the need to have Continuum Cyberstation and Continuum controllers. https://community.se.com/t5/Building-Automation-Knowledge/Conversion-of-Continuum-devices-from-i2-to-b3-and-vice-versa-in/ta-p/448337    To convert i2 field devices into b3 BACnet (or vice-versa) from CyberStation Contact PSS and request the conversion files for the specific model(s) you wish to convert. Follow the procedure detailed below or as per the attached document. To swap the firmware of any non -V i2 device from one protocol to the other (in this case, from Infinet to BACnet b3), you use the following procedure.  For more information, see section 1.3 “Converting Infinet i2 Field Devices to BACnet b3 Devices from CyberStation” below. NOTE: This procedure was developed by Schneider Electric’s R&D and tested in the Product Support Services (PSS) lab.   Before starting the procedure, you need the following items: An I2 device(s) to be converted. A Continuum CyberStation with i2 device(s) configured and online. A special, conversion b3 upgrade file for the appropriate device model as provided by PSS A b3 bootloader file for the appropriate device model, provided by PSS Physical access to the device.  You need this to push its Restart switch or to access the switch or breaker where you can shut off power to the device to force a restart. A bCX4040 controller configured in CyberStation xP Expansion I/O Note If the device to be converted from i2 to b3 has any expansion modules attached, make sure the modules do not exceed the power capacity of the expansion port (180 mA), it has been observed that the b3 devices adhere more strictly to the 180 mA limit than the i2 devices, resulting in loss of operation on IO channels located on the Expansion Port if the power limit is exceeded.  See attached xP Expansion IO Datasheet for information on power consumption of each xP IO module.   1.2 Preparing the Field Bus for the i2 to b3 Device Conversion To ensure a smooth conversion, it is necessary that you reduce the traffic on the field bus as much as possible in order to provide the necessary bandwidth to the upgrade operations required for the conversion. Before starting the process with the conversion file, be sure to follow these instructions.    To prepare the field bus for the i2 to b3 device conversion Disable all the programs in all the devices residing in the field bus. Close all Continuum Workstations except the one performing the upgrade. In the Workstation performing the upgrade, close all graphics, List views, and anything else that could be polling data from the field bus. Make sure MS/TP field bus is on same baud rate as Infinet field bus, mainly 19.2K 1.3 Converting i2 Field Devices into b3 BACnet from CyberStation You can convert Infinet i2 field devices into b3 BACnet field devices by swapping the firmware of any non -V model i2 device. IMPORTANT: When using this procedure, be aware of the following guidelines: It applies ONLY to the firmware or communication protocol (Infinet or BACnet) of the device. It does not convert the control application in the device. Following conversion, the device’s memory is cleared, so you need to configure a new control application. It may result in a loss of critical data if not performed properly. Before beginning, ensure that all important data is backed up in the event of data loss or the device losing its application and becoming non-operational.  For more information, see section 1.1 “Introduction” above. To convert i2 field devices into b3 BACnet from CyberStation Contact PSS and request the conversion files for the specific model(s) you wish to convert. You will be provided with an application file (namely, i2920toB3920B4.500077.upd) and a boot loader file (namely, B3920BootB4.500077.upd). From CyberStation, edit the i2 device and record its Serial Number and Infinet id. Consult the General tab to locate this information. From the Runtime tab, perform a Reset to clear the device’s database. Upgrade the i2 device using the application file provided by PSS. Once the upgrade is complete, the i2 device stays Offline since its communication protocol has now been swapped from Infinet to BACnet. Disconnect the device from the Infinet field bus of its host master controller (for example, a CX9680 or a bCX9640). Connect it to the bCX4040 MS/TP field bus. (MAKE SURE MS/TP FIELD BUS IS RUNNING AT SAME BAUD AS INFINET FIELD BUS DEVICE WAS ON, NAMELY 19.2K BAUD) In the bCX4040, configure a b3 device using the appropriate model as well the Serial Number and ID recorded previously. NOTE: You will need to provide BACnet Device ID. Typically, it will be the same as the Serial Number. You can also use a Learn to bring the device online under the bCX4040 and automatically assign the model, id etc.  Refer to this Knowledge Base article on using the serial number for the Device ID.  Remember here to set the Comm Port for comm2. Restart the device either by power cycling or using the restart button. The device will come online under the bCX4040 as a b3 device. Perform an Update b3 OS operation to send the appropriate b3 boot loader file provided by PSS. Go to the Runtime tab, and reset the device once the update is finished. Once the device reboots and comes back online, you can confirm it has the right boot loader by looking at the device from the BACnet side. The screenshots that follow display the before and after results of the i2 to b3 conversion process. Before: After: NOTE 1 If Continuum system is not available it is also possible to convert i2 to b3 using RoamIO and EBO server using the following steps Disconnect device from field bus and connect RoamIO directly to i2 device. Use InfinetServiceTool to send the application conversion file to the i2 device. After the uprev operation is done disconnect RoamIO and cycle power to the i2 device Connect converted device (now a b3) to MSTP of AS-P or other EBO server that supports BACnet MSTP Perform a b3 learn operation to bring the device online Right click the b3 device and proveed to 'Device->Update firmware...' Navigate to appropriate boot loader file for the b3 model After uprev of boot loader is complete, cycle power to the b3 device. NOTE 2 Similar steps can be used to convert b3 device to i2 device. Make sure to use the V2 version of the b3 to i2 conversion files as it was found the original set of b3 to i2 conversion files did not work in some cases. Please note that once a b3 device has been converted to i2 using this procedure the device will ONLY accept conversion uprev files, attempt to uprev using regular uprev file will result in the following error:   This Uprev file does not match this type of controller. This applies to b3 to i2 conversion only, it does not apply to i2 to b3 conversion.

Issue What is the unit load of a TC900 thermostat and what are the bias and termination requirements when used with a SmartX Server. Product Line EcoStruxure Building Operation, Field Devices Environment TC907-3A4LMA TC907-3A4DLMSA TC907-4FMSA TC907-3A4DPMSA TC907-3A4DPMSA-24 TC903-3A4LMA TC903-3A4DLMSA TC903-4FMSA TC903-3A4DPMSA TC903-3A4DPMSA-24 SmartX Server Cause Documentation does not state the RS-485 transceiver type for the TC900 range, making it unclear how many devices can exist under a SmartX servers RS-485 serial port ComA or ComB. Resolution Use the Worksheet for Configuration of RS-485 Bus with generic RS-485 devices on Webhelp to determine the appropriate Modbus configuration. The answers to the transceiver interface attributes below can be applied to complete the worksheet. Q1 Failsafe Receiver : The TC900 uses an RS-485 transceiver with an integrated idle-state failsafe receiver. Q2 Data Transmission Speed : TC900 thermostats can be configured to communicate at 4800, 9600, 19200 or 38400 bps. Q4 Isolated Interface : The TC900 does not provide an isolated RS-485 interface. Q6a Measured Resistance : With no electrical connections to the TC900, the measured resistance between the RS-485 low-side (-) signal and the communications common is 8.2K ohms. Based on this the unit load of the TC900 is 1.46 (12.000/8,200) Bias requirements and number of devices If there are only TC900 devices on the RS-485 bus then Generic RS-485 Network Device configuration 1 applies, configuration becomes very simple and no node or distance reductions are called for. The failsafe receivers can typically operate with no added bias resistors. Connect a 120 ohm termination resistor across the + and - data lines at the head end of the bus (typically at the SmartX server). Connect another 120 ohm termination resistor across the + and - data lines on the last node at the far end of the bus. Connect the shield drain wire to earth ground terminal rail in the panel with the SmartX server. This is the only ground connection of the shield for the complete cable segment. Connect the RET/Shield terminal (see the figure below) on the SmartX server to the ground rail in the panel using a 12 AWG (3.31 mm²) to 18 AWG (0.82 mm²) wire. Since the TC900 has a unit load of 1.4 the maximum number of devices that can be placed under each comm port using this configuration is 21 (31.5 / 1.46 = 21.5) Also check out the SmartStruxure-RS485-Controller Unit Load Quick-Help video on the Exchange. Note:  Adding an RS-485 Repeater at this point provides another 32 Units Loads to the Network which can be continued up to the Architectural Maximum defined for the hosting controller.

Issue What ground connections are required when wiring a voltage input? Product Line EcoStruxure Building Operation Environment AS/ AS-P Power Supply AS-B Universal Input Modules 0-10V, 0-5V sensors Cause The required connections are different for isolated and non isolated voltage inputs. Consideration of the system grounding is also required. Resolution If your input sensor is isolated it can be directly connected to the UI and RET terminals of the Universal Input module. An isolated sensor will have 4 terminals (2 power terminals G0 and G, 2 output terminals M and X) the power ground G0 is not directly connected to the output ground M terminal. However for non isolated sensors (usually 3 terminal devices) the signal terminal X will be wired to the UI input, but the sensors signal common G0 should be wired directly to the Signal Ground for the installation, not to the RET terminal of the IO Module. On every Input modules ensure that one RET terminal from the IO Module is wired directly to the Signal Ground. Full details of the required wiring and an example wiring drawing showing isolated and non-isolated voltage inputs can be found in "Wiring" section of the Hardware Reference Guide available on the Download Center or in WebHelp: Wiring.

Issue How to be redundant with your intelligent Building Management System (iBMS) Product Line Andover Continuum, EcoStruxure Building Operation, Field Devices, Satchwell Sigma, Security Expert, TAC INET Environment Existing intelligent Building Management System Open Mind High Availability Solutions (Deprecated by manufacturer) everRun MX ztC Edge Cause In engineering, redundancy is the duplication of critical components of a system with the intention of increasing the system's reliability. To be redundant with an intelligent Building Management System (iBMS) would take on two possibilities. Have an alarm on critical points alerting personnel who move into action quickly replacing control boards or devices in the event of failure. Have secondary backup controllers which upon failure, which are used to control devices resuming functionality. This is accomplished through programming the BAS with event sequences triggered from alarms or flags noting the failure. Redundancy capabilities and feasibility are site specific. Ascertaining failure in boards, points, or devices is crucial to creating secondary measures to keep seamless processes going and resume with functions.   Error detection and correction with maintenance is often the best practice for preventing failure. Worn components are the leading cause of failure, followed by a lack of planning and consideration in the protection of electrical components through power surges or failures.   For the database, backups including automated backups for MSDE, SQL Express, and Full SQL are available. For further information on database backups and options, take a look at Microsoft SQL Management Studio. For Host Computer backups, look at adding a secondary computer which replicates the database and can capture transactions and messages should a failure with the primary host computer take place. Also work with the local IT department to keep machines up to date, safe, and clean of 3rd party applications which may interfere with integrity. Schneider Electric’s building management systems are designed such that building control continues even when controller to server communication is disrupted. The BMS server is home to a database of alarm and historical data, as well as system parameters and programs. When a server or its network connection fails, the collection of data from building controllers halts until the problem is resolved. For data critical applications, this solution provides an environment capable of preventing the data loss that results from these types of failures.  Although we do support its use with EcoStruxure Building Operation, Security Expert, Continuum, I/NET, Vista, Sigma, and I/A Series as a disaster recovery solution, we do not provide direct support for EverRun.

Environment Building Operation Automation Server Premium Cause The design in question is a 3-storey accommodation building which includes 1 x BMS panel/AS-P per level. However, only 1 x Mitsubishi EW-50E BACnet gateway is being provided for the building. Resolution It is possible to host the same 3rd party BACnet device in multiple AS-Ps. Some caution is required, however, because if the user makes changes to an object in that device through one AS-P, that change may not be reflected in other AS-Ps. When viewing runtime variables, such as 'Value' and 'Status Flags', this is not a problem because the EBO server will always get new values from the wire. Where the problem can present itself, is when changes are made to configuration values because these are only updated in an EBO server during an upload operation. For example, if you set the hi-limit and low-limit values in an analog-value object from one AS-P, those values will not be updated in other AS-Ps until you do an upload of that object.   The other place where this problem may present itself is in schedules. An EBO schedule only writes values to a device when that value changes. For example, if you have a schedule configured to change the setpoint to 65 degrees at 5pm, EBO will only write a value of 65 if the current 'local' value is not 65. If this schedule only writes 1 time per day and someone has set the value to 70 from another AS-P, the first AS-P does not realize the value has changed so that schedule will not generate a write request to set the value to 65 (it will stay at 70). However, if you have a program or trend-log monitoring the value, the AS-P will be tracking that value and realize it is not 65 so you will see a write request at the scheduled time.   The system works this way because reading all values of all devices and all objects all the time is simply not practical. As long as the user is aware of how the system is designed, they can avoid these potential issues.   Make sure to use Static IP, so IP do not change, or you get multiple DHCP servers on the same network.   Another alternative is to host the BACnet device in one AS-P only, then using internal bindings to share the data with other AS-Ps.

Issue When attempting to save & deploy a function block program using Modernized Programming, the following errors are seen: EBO 2022 - Deploy program error: The program was not deployed! (Error Code - 1073740940) EBO 2024 - Deploy program error - Invalid data "Empty binary file' Invalid data  Product Line EcoStruxure Building Operation Environment EcoStruxure Building Operation WorkStation EBO 2022 EcoStruxure Building Operation WorkStation EBO 2024  Function Block Programs (Builder for Function Block) Cause Related to known issue Modernized Programming Builder program error during deploy This is when the TEMP / TMP User variable folder paths contain a space; this can be edited in the Environmental Variables.  Resolution Edit the TEMP and/or TMP paths so that they do not contain any spaces.  To edit the Environmental Variables, follow these steps:  1. Click on the Start Menu button located at the bottom-left corner of your screen. In the search bar, type "environment variables" and press Enter.  Click on the "Edit the system environment variables" option from the search results. This action will open the System Properties window, which contains various tabs and settings for your computer. In the System Properties window, click the "Environment Variables" button located at the bottom right. Clicking this button will open another window specifically for managing environment variables.  In the Environment Variables window, under the "User variables" section, "Edit" the path that contains any "spaces".  These paths can be located anywhere on this PC.  User variables apply only to your account, while system variables affect all users on the computer. Choose accordingly, and then add or edit variables as needed. Once you have completed these steps, your new or edited environment variables will take effect.  Restart WorkStation, and the program should now deploy successfully.   

Issue Some BACnet devices advertise support for services such as RPM, COV, etc but malfunction when the service is used. An example of such a device is the Johnson Controls TEC2627VVT which advertises support for RPM but fails to upload its objects when SBO uses RPM to get the object list. Product Line EcoStruxure Building Operation Environment BACnet Automation Server Enterprise Server Cause Some BACnet devices with inconsistent protocol implementation cannot process BACnet services such as RPM, COV, etc. Resolution Feature Supported in Version <no-rpm/> 1.8.1 and higher <no-cov/> 1.8.1.23701 and higher <ignore-unhosted-devices/> 3.2.3.9005 and higher (*)   Users can create a rule under the BACnet interface to configure SBO not to use the service. Some rules are global, while others can be for specific BACnet devices. For particular BACnet devices, they are specified by 'Vendor Identifier' and 'Model Name,' which need to match exactly as shown in that device's Properties - Advanced Tab.   Ensure you have installed the version that supports the feature you want to change. Setup file using the no-rpm rule. Use a text editor like 'Notepad' to create a text file or download the same file below. Enter the device's vendor ID (5)  and model name (TEC2627VVT) followed by the rule (no-rpm) using the format seen in the screenshot below. Save the file to the desired location on the PC with a name aiding later identification. Under the BACnet interface, create a new 'Document' object in the 'Application' folder. NOTE: The object MUST be named 'service_blacklist' in all lowercase. Click 'Next,' import the text file created in step 1, and save the 'Document' object. Restart the Server  Once the device is on the block list, SBO will not send 'readPropertyMultiple' requests to the device using only individual 'readProperty' requests. Add the service_blacklist to the EBO Server. Add the no-cov tag if you would like to block that service for this device:  Extended for multiple devices from different vendors simultaneously using this example for reference.   One can add a global rule using this syntax to ignore unhosted devices. * NOTE: It is recommended to remove <ignore-unhosted-devices/> after upgrading to EBO 4.0/2022 and higher because this feature is supported in the BACnet Interface Properties and BACnet Device Discovery view. Device Discovery for BACnet Controllers and IO Modules (se.com)  Once the Server has restarted, check the trace.log file and search for service_blacklist, there should be entries similar to this.
