Issue Creating an Extended Trend Log for b3 (Infinet i1/i2) Point and Value Logs Product Line EcoStruxure Building Operation Environment b3 BACnet Controller Infinet i1 & i2 Controller Building Operation Automation Server, AS, ASP, ASB Extended Trend Logs (ETLs) Cause Using an extended trend log to store log records for long periods of time. The extended trend log is often saved on a higher-level server with more storage capacity. This extra storage capacity enables the server to store more records before overwriting the old ones. For more information, see WebHelp. Configure extended trend logs for b3/i1/i2 devices the same way as configuring extended trend logs in other Building Operation devices. There is one difference, however. do not use smart logs when configuring extended trend logs in b3 BACnet devices. Instead of using smart logs, use the Maximum Transfer Interval property to specify the transfer interval. Resolution In Listview, select the b3/Infinet Object (point or value), click Properties/Advanced Multiply the "Log records" by the "Log interval" to calculate the maximum transfer interval. The "maximum transfer interval" is the frequency at which the extended trend log will transfer log records from the b3/Infinet Object before any entries in the b3/Infinet controller log are overwritten Right click the object, choose New then "Extended Trend Log" In the Create Object box, set Smart Log to False, Set the "Maximum transfer interval" to less than that calculated above (2) Click Create For Infinet systems always refer to Infinet under the hood otherwise the creation is as the Webhelp for creating BACnet B3 Logs In theory it would be possible to create the Extended Trend Log in an ES (where there is more storage capacity), but this could introduce other timing and bandwidth issues, so it is usually best to keep the first Extended Trend Log in the AS, then extend this to a second Extended Trend Log in the ES, as shown. (the second ETL in the ES scan use smart logging in the usual way) If significant logging is required then External Log Storage should be considered. (the B3 or i1/i2 logs still need to be collected via Extended Trend Logs)    

Issue Capturing packets from Zigbee Standard Security Network shows packets marked Bad FCS or Encrypted Payload Product Line EcoStruxure Building Operation Environment Building Operation Automation Server Building Operation Room Controller Cause Zigbee Standard Security Networks implement multiple keys to encrypt data for the Zigbee Network and each device Resolution This resolution assumes you have a Zigbee adapter that can capture packets in Wireshark.   Ensure zigbee_pc_keys are available in each profile you are going to use to analyze the Zigbee packets. The file location is generally: %AppData%\Roaming\Wireshark\profiles\<Profile Name>\zigbee_pc_keys   Open Wireshark and configure the Zigbee adapter NOTE: Please substitute your adapter name if not using the TI CC2531 adapter. Open Wireshark Click the gear next to the 'TI CC2531 802.15.4 packet sniffer' Select the known channel (11-26) and click Save Click on 'TI CC2531 802.15.4 packet sniffer' to start capturing Update formatting to resolve Bad FCS packets Go to Edit -> Preferences -> Protocols Select IEEE 802.15.4 Depending on your Wireshark version, check or "TI CC24XX FCS Format" or set FCS format = "TI CC24xx metadata" Add default link key for Zigbee Alliance Go to Edit -> Preferences -> Protocols Select ZigBee Set Security Level = AES-128 Encryption, 32-bit Integrity Protection Click Edit next to Pre-configured Keys Click + and Enter Wireshark Key from below, Byte Order = Normal, and Label Enter the Zigbee Alliance Default Link Key Key = 5A:69:67:42:65:65:41:6C:6C:69:61:6E:63:65:30:39 Key Value = 5A6967426565416C6C69616E63653039 Remove colons (:) for entry into Wireshark ByteOrder = Normal Label = ZigbeeAlliance09 Find and add Standard Network Key Ensure you have configured the default transport key (above).

Issue How to add a third party LonWorks device? How to create a LonWorks device template? Why is a device template not available after import? Product Line EcoStruxure Building Operation Environment Building Operation version 1.8 and above Building Operation WorkStation Cause In order to add a third party device, need to create a device template (XIF file) for it. Device templates must be created in the server that the controller will created under. If a third party controller is going to be added to an AS-P that is associated to an ES, then the template must be created when logged into the AS-P directly. Resolution To import a device template   Log in to the SmartStruxure Server in which the device will be added underneath. In Workstation, Right mouse click on the Server and select LonWorks then import device Template. In the XIF file box, select the XIF file to import. Click Import. In the Template Name field, type a name for the template. Click OK. In the Import Device Template box, click Close. Now, this third party device template will be listed when adding a device into the LonWorks network. Note: If the device template refers to NVT or CPTs not on your system, you will be prompted to import necessary resource files. When the resource files have been imported, the device template import restarts. When finished, the device template is imported and available when creating a new device.

This configuration is supported and has been used many times.

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.  

Issue With the same time interval as the trend log, the traffic on the LonWorks network increases for a short period. This can be seen by a spike in the LPA log when viewing the bandwidth. Product Line EcoStruxure Building Operation Environment Building Operation Workstation Lonworks Cause The LonWorks traffic increases with the same time interval as the trend log. Resolution To ensure we could log values in the trend log from a LonWorks device, a subscription is set up about 30 seconds before the value should be logged. After the value is logged, the subscription is removed until the next log interval. A good solution to flatten a spike caused by this issue is to stagger the times of the LonWorks trend logs. This will ensure the subscription for all the logs do not happen at the same time.

Issue When comparing values of Modbus registers within WorkStation and Modscan the values do not match. Product Line EcoStruxure Building Operation. Environment Building Operation Enterprise Server. Building Operation Automation Server. Cause The third-party Modbus device does not support single register requests. Modscan was set to poll 10 registers as a group poll and giving the correct responses. The Modbus request in the Enterprise Server or Automation Server was polling individual register one at a time. This resulted in incorrect responses from the third party device Resolution Add a Modbus register group to the Server then add the Modbus points to this group. This will cause the Server to poll multiple registers in 1 request and get the correct response from the third party Modbus device.   For more information on Modbus grouping refer to the EBO Webhelp Modbus Register Groups topic

Issue How to read individual bits from a Modbus Holding Register that holds a 16-Bit Word and represent each Bit as a separate Digital point Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Server Building Operation Automation Server (AS, AS-P, AS-B) Modbus TCP/IP Modbus RTU (RS485) Cause There is a requirement for a Modbus Holding Register that is a 16-bit unsigned value, each bit represents a digital state in the Modbus device and to replicate this as 16 separate digital states in EBO. The 16-bit unsigned value is an integer with a range of 0 to 65,535 and needs to be converted into 16 digital values. Resolution Use a Modbus Digital Input point for each bit required. Each object will be configured to read the same Modbus register address, but with a different bitmask value applied prior to evaluating the value. For example: Read Modbus Holding Register 40123 with a value of 32769 (16-bit unsigned) and decode bits 0, 8, and 15 as three separate Digital points Since the actual Value of 32769 being read at address 40123 is shown in Binary as 1000000000000001 it can be seen that Bit 0 and Bit 15 should return TRUE while Bit 8 should return FALSE Configure each point as follows: Modbus Digital Input Point 40123 bit 0 Register number 123 Register type 16 bit unsigned Read function code 03 Bit mask - enable only Bit 0   Modbus Digital Input Point 40123 bit 8 Register number 123 Register type 16 bit unsigned Read function code 03 Bit mask - enable only Bit 8   Modbus Digital Input Point 40123 bit 15 Register number 123 Register type 16 bit unsigned Read function code 03 Bit mask - enable only Bit 15   Additional information can be found in the EcoStruxure Building Operation - Technical Reference Guide - Search for Bitmask.   If you need to break this bit information out for programming this can be done with a FB application and just binding the full 16 bits to the FB as shown here.

Issue When looking in the EcoStruxure Building Operation Architectural Guidelines for the maximum number of Xenta and LonWorks devices per server, is a TAC Xenta I/O module placed under a TAC Xenta 300/400 counted as a LonWorks device? Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Server Building Operation Automation Server Cause The SmartX Server or Enterprise Server doesn't know that the TAC Xenta I/O module exists if it is placed under a TAC Xenta 300/400. The SmartX Server or Enterprise Server only communicates with the TAC Xenta 300/400 and not the TAC Xenta I/O modules under it. Resolution The TAC Xenta I/O module does not count as a LonWorks device in the EcoStruxure Building Operation Architectural Guidelines if placed under a TAC Xenta 300/400. This also means a TAC Xenta I/O placed under a TAC Xenta 300/400 does not count as a  Hosted Node or Connected Product.

Issue Delete Lonworks Device Templates Product Line EcoStruxure Building Operation Environment Building Operation Enterprise Server Building Operation Automation Server LonWorks devices Cause Some templates are preloaded with the software; if the particular device does not have a supplied template, you can upload an XIF file. This is done by selecting File/LonWorks import/Device Template and then importing the XIF from the manufacturer. An unused Device Template causes no harm to the system; however, there may be a desire to remove a Device Template. Resolution EBO 3.x and later Device Templates can be added and deleted in all device types using the Resource Manager - Device Templates tab SBO 1.x and  EBO 2.x Device Templates cannot be directly deleted from Building Operation WorkStation, however, they can manually be deleted from the  Enterprise Server file system. When a device template is imported, you should understand if the template should be located in the Enterprise Server or an Automation Server.   If the device template is located in an Automation Server, it can only be removed by upgrading the Automation Server using the Device Administrator (you can stay with the current release). If the device template is located in an Enterprise Server, it can be removed using the following process. Locate the template path in the Building Operation database (e.g., C:\Documents and Settings\All Users\Application Data\Schneider Electric StruxureWare\Building Operation 1.3\Enterprise Server\db\UDT\public\public\lon\devicetemplates) Note: in newer releases, the path has changed slightly, e.g., For V1.8.1: C:\Documents and Settings\All Users\Application Data\Schneider Electric StruxureWare\Building Operation 1.8\Enterprise Server\db\UDT\pu\public\lon2\devicetemplates   Delete the two template files named Pidxxxxx, where xxxxx are the numbers or letters in parenthesis behind the device template's name visible in WorkStation. After deleting the templates, you may need to restart the Enterprise Server.
