Issue Internal counter stops counting. Product Line EcoStruxure Building Operation Environment Script Function Block Counter 167777216 Cause When this script is used it stops counting at 16777216. Numeric Output CountOut   Main: CountOut = 16777100 goto Counter Counter: CountOut = CountOut + 1   Resolution This issue was identified in the early days of Continuum and is regarded as a limitation, not a defect. Explanation - Internally the Script handles all numbers as IEEE754 single precision floats, which means that 16777216 is handled as 1.6777216E7. Adding 1 to 16777216 is unrecognizable in that representation. Using an IEEE754 converter at https://www.h-schmidt.net/FloatConverter/IEEE754.html, one can see that 16777216 and 16777217 have the same binary representation. The point at which the counter will stop, will depend upon the value being added each time, so adding 0.9 will count to a different number than adding 1. The counting range can be extended by two or more variables as shown below. Numeric Output CountOut Numeric CountOut1 Numeric CountOut2   Main: CountOut1 = 16777100 goto Counter1   Counter1: CountOut1 = CountOut1 + 1 CountOut = CountOut1 if CountOut1 = 16777216 then goto Counter2   Counter2: CountOut2 = CountOut2 + 1 CountOut = CountOut1 + CountOut2

Issue Automation / Enterprise Server configuration very slow Attempting to make any configuration changes in the AS such as creating a new point/value or modifying existing objects is extremely slow. Note: This applies to the ES as well although less of a problem since the ES has better resources than the AS. CPU usage as seen in the Status Information of the server is very high. (above 80%) Question marks are shown on many objects in the application folder of third party BACnet devices that have been uploaded to the AS Enterprise Server takes a long time to startup (15 minutes) before allowing users to log on with Workstation.  Deleting the BACnet Interface allows log on with 2 - 3 minutes on a restart. Product Line EcoStruxure Building Operation Environment Automation Server Enterprise Server BACnet Cause Uploaded BACnet devices contain unresolved references to notification class object(s) Resolution Ask for SE.SBO.ES-AS-1.5.0.1501-Hotfix. (SE.SBO.WS-1.4.1.16001-Hotfix for 1.4.1, there is no hot fix for versions before 1.4.1) After applying the hot fix the server should become responsive. The unresolved references can typically be cleaned up by creating a BACnet Notification object in the application folder of the third party BACnet device proxy that reside in SBO and manually setting the Instance ID to 0 (zero) NOTE: Cases have been seen where multiple notification class objects must be created using instance IDs 0,1,2,3,4 in order to clean up all the unresolved references. A few minutes after the notification class object with the proper instance ID is created the question marks should disappear from the icons and created notification class object will show up in the intrinsic alarm property as seen below.   If creating the notification class objects with the above instance IDs does not resolve all the references a backup of the server can be provided to PSS, a PSS/R&D engineer can look directly at the database to determine the proper instance IDs the unresolved references are looking for.

Issue Configuration of multiple BACnet BBMD's over several subnets Product Line Andover Continuum, EcoStruxure Building Operation Environment Bacnet BBMD Cause Bacnet Broadcast communication through IP router Resolution Configuration of multiple BBMD's over several subnets: INCORRECT METHOD For example if there are 4 subnets on the same B/IP (BACnet IP Network): Subnet 1: Workstation setup as a BBMD with an entry in the Broadcast Distribution Table for each BCX Subnet 2: BCX setup as a BBMD with an entry in the Broadcast Distribution Table for itself and the Workstations BBMD Only. Subnet 3: BCX setup as a BBMD with an entry in the Broadcast Distribution Table for itself and the Workstations BBMD Only. Subnet 4: BCX setup as a BBMD with an entry in the Broadcast Distribution Table for itself and the Workstations BBMD Only. The BCX's do not reference any points from each other. Since there is no data sharing between the BBMD's, one might think that in each BCX's Broadcast Distribution Table that there would only be a need to add one entry for the Workstations BBMD. Sounds like with this setup we'll reduce traffic by only adding the one entry in each BCX's BBMD Broadcast Distribution Table. The above scenario could in fact slow down a network and cause unnecessary traffic.   The supported method is that every BBMD on a B/IP network have the same routing tables(better known as the Broadcast Distribution Table) as in the below configuration. CORRECT METHOD For example there are 4 subnets on the same B/IP (BACnet IP Network). Subnet 1: WS BBMD with an entry in the Broadcast Distribution Table for itself and all BCX's setup as BBMD on the same B/IP. Subnet 2: BBMD with an entry for all BBMD's(including self) in the Broadcast Distribution Table on the same B/IP. Subnet 3: BBMD with an entry for all BBMD's(including self) in the Broadcast Distribution Table on the same B/IP. Subnet 4: BBMD with an entry for all BBMD's(including self) in the Broadcast Distribution Table on the same B/IP. The entry below can be found in the BACnet Standards 2004:   J.4.3 BBMD Concept Each IP subnet that is part of a B/IP network comprised of two or more subnets shall have one, and only one, BBMD. Each BBMD shall possess a table called a Broadcast Distribution Table (BDT) which shall be the same in every BBMD in a given B/IP network.

Issue When configuring a BBMD what is the Broadcast Distribution Mask and what are the valid settings for the field. Continuum EcoStruxure Building Operation Product Line EcoStruxure Building Operation, Continuum Environment Building Operation Automation Server Building Operation Enterprise Server Continuum CyberStation bCX4xxx Cause Documentation Resolution When configuring a BBMD the BACnet protocol defines two methods of propagating the broadcasts messages to other networks. The two methods are referred to as One-Hop also known as a Directed Broadcast and Two-Hop.   Note: In this article the subnet mask is shown using Classless Inter-Domain Routing(CIDR) notation. An IPV4 address is 32 bits long, CIDR notation defines the number of bits used for the subnet mask. The most commonly used are: /8 or 255.0.0.0 /16 or 255.255.0.0 /24 or 255.255.255.0 /32 or 255.255.255.255 One-Hop With the One-Hop method the local BBMD transfers the message directly to the remote devices via the remote router. In this case the IP routers have to support the transfer of IP broadcast messages to remote IP subnets Figure 1 Figure 1 above illustrates the one-hop method, when the bCX1 which has been configured to take the role of BBMD for network 172.16.0.0/16 detects broadcast messages such as WHO-IS, I-AM etc, it sends a message directly to the broadcast address of the 192.168.1.0/24 subnet, it is then up to Router2 to send the directed broadcast to all devices on the subnet. Any device on the subnet that is acting as a router to other networks will then also re-broadcast the message on those networks. (i.e a bCX hosting an MSTP network on COMM2)   Two-Hop With the Two-Hop procedure a BBMD device transfers broadcast messages to a further BBMD in the remote IP subnet, which then distributes the messages in its local network as IP broadcast messages for its IP subnet. Any device on the subnet that is acting as a router to other networks will then also re-broadcast the message on those networks.(i.e a bCX hosting an MSTP network on COMM2) Figure 2 Figure 2  above illustrates the two-hop method, when the bCX1 which has been configured to take the role of BBMD for network 172.16.0.0/16 detects broadcast messages such as WHO-IS, I-AM etc, it sends a unicast message to each BBMD device on its table, it is then up to each BBMD device on each subnet to send a broadcast that will be heard by all devices on the subnet. Which distribution mask should be used? As mentioned earlier, in order for the one-hop method to work, the router on the remote subnet MUST be configured to process incoming messages sent to the broadcast IP address, the two-hop method on the other hand is guaranteed to work, so when in doubt use the two-hop method. Most sites use two-hop distribution for the reason stated above,, the only obvious disadvantage of the two-hop method is that it is a little more verbose than the one-hop method since the message appears twice on the subnet, once as a unicast sent to the BBMD device and then again as a broadcast sent by the BBMD device. In Building Operation and Continuum the distribution mask defaults to the two-hop method (/32 or 255.255.255.255) How to configure the distribution mask For one-hop enter the subnet mask of the remote network in the distribution mask, the system will apply the mask to the IP address to obtain the broadcast address for the remote network. For two-hop enter 255.255.255.255, this tells the system not to do a direct broadcast and instead do a unicast to the remote BBMD device. Sample distribution mask In the BBMD table of a bCX shown in the screen shot above, BDT #1 and #3 use the two-hop method while BDT entry #2 uses the one-hop method.

Issue Too much LON communications traffic can cause LON communications errors. Product Line TAC IA Series, EcoStruxure Building Operation Environment I/A Series MNL 800 Building Operation Automation Server Premium LON Network  I/A Series R2, AX, N4 Jace LON Network Cause Sending output LON SNVT values too frequently or more often than reasonably needed. Resolution There are a series of NCI (configuration) objects that control the transmission and reception of these data values on the LON network. One of four NCI objects (nciSndHeartBeatA, B, C, or D) is assigned to each NVO object in the application program. This value regulates the periodic LON transmission queuing of the NVO object values for each binding. One of four NCI  objects (nciRcvHeartBeatA, B, C, or D) is assigned to each NVI object in the application program. This value regulates the fallback timeout for each NVI object value. If a value is not received via the binding in this time period, the NVI object value will revert to its application-defined default value. In an MNL-800 controller, there are two additional NCI objects that are used to regulate the flow of data onto the LON network. The nciMinOutTime object is used to throttle the transmission of all data values queued to be sent via bindings over the LON network. This NCI object sets the transmission time interval between each NVO value being sent on the network. The important fact here is that the product of the number of bound NVO values times this interval (nciMinOutTime) must be LESS than the shortest nciSndHeartBeatX (X=A, B, C or D) interval. For example, if the Send HeartBeat is set to the default of 120 seconds and there are 60 NVO SNVTs bound from this controller, the nciMinOutTime must be set to a value of fewer than 2 seconds.  The recommendation for setting this SNVT value one half the shortest nciSntHrtBr divided by the number of NVO SNVTs bound from the controller.   The nciMinPropTm object is used to regulate the transmission queuing of changing bound NVO object values. This timer acts as a time-based filter to prevent a rapidly changing NVO value, such as a constantly changing temperature, from overwhelming the communication capacity of the LON network. Typically this value is set to a value of 1 to 5 seconds. Additional information can be found in Chapter 6 of the WorkPlace Tech Tool 4.0 Engineering Guide (F-27254). BACKGROUND: This section is provided to give the reader a basic understanding of bound LON communications, as applied to LON controllers in general. Data communications across a LON network is accomplished by using a LON Network management tool to create a binding between a device with a data source (NVO object) and one or more devices with data receivers (NVI objects) in other LON controllers. The device containing the data source will send the bound data value at a periodic rate, as defined by the associated SendHeartBeat NCI object, and whenever the value of that object changes. If the NVI object does not receive a value from the sender (bound NVO object) within a specified time period, as defined by the associated ReceiveHeartBeat NCI object, the NVI object will use a local fallback value until such time as it receives a new value via the binding.

Issue How to search for points, names, or descriptions in EcoStruxure Building Operation Product Line EcoStruxure Building Operation Environment Building Operation WorkStation Cause The EcoStruxure Building Operation search feature can be performed on an entire database or on individual controllers / folders. This can help reduce the amount of time it takes to locate multiple points when creating mirrored points. Resolution How to search for specific names in EcoStruxure Building Operation Right click on the folder, object, or controller you would like to search in and click "Search. Note: When the search is narrowed down to specific areas of the database it will be able to complete the search faster than performing a full database search." In the search field type in the name that you are looking for. In this example the search is for snvt*. This will locate all points underneath the controller that begin with snvt in the point name. After a few seconds, depending on the size of the search area, the results will be displayed in the window to the right. In order to filter the search further, you can set different search parameters under the search field.

Issue What does the Persisted Data mean in a Log Processing Trend Log and how does if affect the data? Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Server v. 3.2 onwards Building Operation Automation Server Premium v. 3.2 onwards Building Operation Automation Server Bundled v. 3.2 onwards Cause As described in KB article Log Processing Trend Log records not transferred to Extended Trend Log, if Persisted Data is false the data is not saved to the database, but instead recalculated every time the data is required. This has a few effects on the Log data. Constantly recalculating the data can delay displaying the data. With Persisted Data False, the latest log value can be calculated, but if set to True the latest value will only be available after the end of that period as below: This can have an effect if the data is being used in WebStation Dashboard. In the example below the last 30 days is being viewed:   Resolution If the log data is required frequently and multiple logs are required, the operation of opening the logs may take a while. In that case it is better to switch Persisted Data to true. See Known Issue WebStation Dashboards take up to 20 minutes to open using External log Storage and Log Processor Trend Logs for more information.   The Log value for the latest period is likely to vary depending if the persisted data is true or false.

Issue Test and air balance procedure for balancing airflow Product Line TAC Vista, EcoStruxure Building Operation Environment Building Operation Automation Server Premium  TAC Xenta 102-AX  TAC Xenta 102-AX Plug-in Cause Each 102-AX controller must be calibrated on-site to report accurate airflow readings.  The LNS Plug-in provides this functionality, but it may not be immediately clear what the correct procedure is to perform a valid calibration. Resolution Check the firmware version of your 102-AX controllers in the plug-in, Node Configuration tab. It will be shown under Program Revision. If it's anything earlier than 2.1.6 then the calibration won't work properly. The airflow setpoint changes but the damper does not modulate to maintain setpoint in the calibration mode. Your options in that situation are to manually manipulate the damper to maintain airflow setpoint in order to facilitate calibration or upgrade the controllers firmware. Also verify that the box is set to "Pressure Independent" mode on the Unit Parameters tab.  Pressure dependent boxes do not use airflow sensors, and therefore cannot be calibrated. To balance the 102-AX in Building Operation version 1.4 or higher where the LNS plug-in is no longer provided, review the article TAC Xenta 102-AX TGML plug-in for Building Operation To calibrate airflow using the 102-AX LNS plug-in:  Go to the Node Configuration Tab. Select "Set Default m & b." This is a good idea before each calibration attempt since incorrect calibration values can make it more difficult to perform a valid calibration. (NOTE: The m & b values can be viewed under the Airflow Parameters Tab of the 102AX LNS plug-in...m = Velocity Pressure Gain & b = Velocity Pressure Offset) Select "Start Calibration." At this point the airflow setpoint should go to the minimum. You can check the Cooling Minimum airflow setpoint on the Airflow Parameters tab. The damper now modulates to maintain the minimum cooling flow setpoint. Watch the VAV Reading (Low) and wait for it to hit the minimum flow setpoint and level out. If the airflow is fluctuating a lot, it could be that the low setpoint is below the threshold the box can confidently supply. Or it could be bad placement of the flow sensor in a turbulent area of the duct. It can affect your calibration greatly if the value is fluctuating too much. A relatively level reading will provide a good calibration. When it levels out, measure the actual airflow with a highly accurate magnehelic hood. Enter the actual value into Reference (Low) and select "Continue." The damper now modulates to maintain the maximum cooling flow setpoint. Watch the VAV Reading (High) and wait for it to hit the maximum flow setpoint and level out. When it levels out, measure the actual airflow with a highly accurate magnehelic hood. Enter the actual value into Reference (High) and select "Finish." The new calibrated m & b values are shown. The gain (m) is shown in the format of multiplier/divisor. Divide the values to get a decimal format of the gain. The closer to 1 this value is, the less calibration was required. actually gains of 2 or more indicate probable airflow reading problems. It may be advisable to reset factory calibration values and try the calibration again. The box should now be displaying values very close to actual measured readings. Test the low and high flow during normal operation using the Status Tab, Right click on the Space Temp and override the space temperature to a value equal to or greater than the Occupied Cooling Setpoint plus half the Cooling Band to drive the airflow setpoint to the cooling maximum airflow setpoint (you can find the Occupied Cooling Setpoint and Cooling Band on the Operating Tab).  With the space temperature already in override, left click the Space Temp to change the space temperature without taking it out of override, and set the space temperature to the Occupied Cooling Setpoint minus half the Cooling Band to drive the airflow setpoint to the cooling minimum airflow setpoint.  With the space temperature in override, right clicking it will take it out of override.

Issue Basic Modbus RTU configuration to read a register from PM800 Power Meter. Product Line EcoStruxure Building Operation Environment Automation Server Modbus RTU PM800 Power Meter Cause Integrate power meters to a Building Operation front end for the user to view data and trend logs. Resolution Here are the steps to Configure a ModBus RTU interface in Building Operation to read the Line Voltage register from a PM800 Power Meter. (Assuming meter has already been properly wired to one of the serial ports on the AS) Create the Modbus Interface, in this case a Modbus Master Network.   Link the interface to a serial port in the AS in the Port Reference field, in this example to RTU device is wired to RS485-COMB   2. Under the interface create the RTU device. In this example the device id is 11, enter the appropriate id for the device. Once the device object is saved, the status should show 'Online' unless there is a communications issue. This is provided you have the online poll interval set. If this is disabled the device will stay offline until a Modbus register is polled and a valid response is received.    You can confirm that Building Operation is able to correctly detect the communications status of the device by disconnecting it from the commport and observing the status change to 'Offline', upon re-connection the status should once again display 'Online'   3. Under the device create a Modbus Point of type AnalogInput to get the value of the Line Voltage from the device. According to the documentation for the PM800 the register holding the line voltage is Function Code 3  and register  1124 The value of the point should now correspond to the line voltage in this case 125 volts.
