Issue Cannot see third-party LON devices when using the I/A Series Lon Device Manager to find and learn the devices on the LON Network.  The third party devices are known to be defined with a specific Lonworks Domain address. When using the I/A Series R2 (Niagara) WorkPlace Pro to commission LON controllers with specific a Lonworks Domain address, configure the Local LON device to match the Domain Length, Domain ID, and Subnet ID programmed in the third-party device. Environment I/A Series R2 (Niagara) WorkPlace Pro UNC 520 Third party LON controllers Cause When a third-party network management tool is used to define and configure / commission a LON network, the commissioning tool frequently uses specified domain address instead of the default "zero-length" domain address.  When using the I/A Series (Niagara) R2 WorkPlace Pro to learn a previously commissioned network, Workplace Pro will not be able to discover the LON devices until it has been configured to match the domain address of the network. Resolution Perform the following steps using WorkPlace Pro to configure the LON interface of the UNC and to learn the LON network. Open the Netmgmt page for the Local Lon Device then set the domain length and domainId to match the domain address of the device.  Apply the changes.  (See example here). Open the Properties page for the LocalLonDevice and select the Engineering tab.  Set the subnetId to match the subnet address of the devices.  (See example here). Recommission the Local Lon Device. Use the Lonworks Device Manager to find and learn the devices on the LON network.

Issue What is the bCX and NCII required bandwidth? 10Mb, 100Mb Network Connections, GSM Modems. Environment Continuum Ethernet level controllers: ACX57xx, Netcontroller II and bCX1 Cause IT Departments often ask for the required IP Network bandwidth for the CX and bCX controllers; as it is not listed on the datasheets. Is there a bandwidth calculator available? Resolution The Network usage of a bCX/ CX/ ACX controller will vary constantly depending on what is happening on the system at the time. It will be affected by user commends, Graphics, Plain English programming, Access events, reloading or re-flashing controllers and time triggered events. The 2nd generation controllers network connection supports a 10Mb half duplex or 100Mb full duplex auto sensing permanent connection. Note: Older 1st generation controllers (CX9200, CX9400, CX9900 series) only support 10Mb half duplex. So a corresponding up to 10Mb or 100Mb connection would be ideal. GSM Modem or other packet based communication networks are unlikely to be able to provide the continuous data throughput required by Continuum. In terms of bandwidth an absolute minimum of 1Mb in both directions is recommended but this will depend on the specific site requirements you have, for example if there is a requirement to update graphic or alarm values within a specific time then a 10Mb connection would be more appropriate. The following Bandwidth Calculator can be used to determine the % network usage on a 10Mb network connection. This was created specifically for typical Access Control projects, so for HVAC applications the following should also be considered: data logging, PE programs passing data, IP based X Drivers. Fill in the appropriate values in Column D for the system: Bandwidth Calculator.

Issue Security Expert PSU has Fault Icon lit and Status Light Flashing Red Every 3 Seconds indicating an issue with PSU Addressing Product Line EcoStruxure Security Expert Environment Security Expert PSU Cause The module address 254 is the default value which all modules are shipped with and is outside the range the controller can accept. This must therefore be changed during commissioning. See Page 41 of the Operator Reference Manual for details. There is an overall limit of 250 modules that can be connected to a single controller with the following limit on each type of module: Keypad Modules: 200 Input Expanders: 248 Reader Expanders: 64 Output Expanders: 32 The module addressing is defined per module type not by the position of that module on the network. You could have all modules at the same address as long as they are all different types. Example: With the following modules we could have all modules be set to use address 1: 1 x Controller 1 x Keypad 1 x Reader Expander (In this case onboard Reader) 1 x Analogue Expander (PSU) Resolution 1. Right Click on the SP-C Controller and select Module Addressing. Change the Address of the Analog Expander (PSU) from its default value of 254 in this case to a value of 1. 2. Then Update all Modules. 3. Select the Analog Expander (PSU) in the System and also change its Physical Address to also be 1. Save the changes. 4. The PSU should now come online and the Fault Icon on the PSU will no longer be lit.

Issue Are Xenta Servers supported in StruxureWare Building Operations? Product Line EcoStruxure Building Operation Environment EcoStruxure Building Operation Xenta 701, 711, 721, 731, 511, 527, 555 Cause Want to use Xenta Server as a controller in StruxureWare Building Operations. Resolution No there are no special support for Xenta servers. But you can add them as normal LonWorks devices. You can only read/write SNVTs from the Xenta server. Normal Lon rules applies here, you can have a maximum of 64 nodes to a segment (we recommend to keep it under that). TAC Xenta Server I/O modules will not be seen in StruxureWare Building Operation, but they will count towards the 64 nodes on the segment. See Maximum number using StruxureWare Building Operation (Scalability and Capacity) for more information on Lonworks units in StruxureWare Building Operation.  

Issue Right after successfully creating a simple XML Web Service all the values show 0 and the Web Service is offline Product Line EcoStruxure Building Operation Environment Simple XML Web Service Workstation Enterprise Server Automation Server Cause Possible cause 1: SmartStruxure Workstation can handle URL's both with and without the final forward slash even if the URL is just an IP address and a port number. The ES or AS can't handle that, and so after creating the variables through Workstation, the Web Service goes offline after it is added to the server. Possible cause 2: The XML file or response is not UTF8 encoded but "UCS-2 LE BOM" encoded or something else. Resolution Solution 1: Add a final forward slash to the Web Service URL - e.g. http://localhost:8000 should be http://localhost:8000/ Solution 2: Make sure the XML file is correctly encoded in UTF8 - you can check and change the encoding with e.g. Notepad++

Device BDT (Broadcast Distribution Table) FDT (Foreign Device Table) ES only limited by memory 64 (up to v1.4) 600 (from v1.5) AS only limited by memory 64 (up to v1.4) 254 (from v1.5) ASB only limited by memory 50 bCX1 32 32 Cyberstation 1024 1024 Always refer to the Architectural Guidelines for the latest information

Issue License Administrator fails install with an "Uninstall failed, installer cannot continue" error Product Line EcoStruxure Building Operation Environment Building Operation License Administrator Cause Building Operation uses Flexera (Revenera) Software Technology for licensing. Other Schneider-Electric products may also use this technology for their licensing. Resolution Check to see if the site has other software programs/products using the Flexera (Revenera) Software Technology. Other Schneider Electric offers such as Unity Pro - IEC Programming Software for Modicon PAC, Power Monitoring Expert & TAC Vista as well as third party programs also use Flexera (Revenera) for their licensing. During installation of the Building Operation License Administrator the dialog below is shown: The default behavior of the Building Operation License Administrator installation program is to install both Building Operation License Administrator and a new local license server instance. If the default behavior is accepted, the installation program will attempt to uninstall any previously installed local license servers. If the Building Operation License Administrator installation program  does not have sufficient access rights to uninstall the license server previously installed by another product a "Failed to install Building Operation License Administrator" error will occur.   Multiple products can share a single Flexnet License server instance. If there is an existing Flexnet install then the License Server checkbox should be unchecked during installation of the Building Operation License Administrator This leaves the existing local license server installed by the other product intact, while still allowing Building Operation License Administrator to run. The license server used by Building Operation License Administrator can easily be changed by the user on the License Server Address tab in Building Operation License Administrator, if necessary.

Issue A site configured a schedule to have 2 different holiday durations during a spring break holiday week. The schedule is not working as expected. The Holiday week is set up as a range for Monday - Friday and assigned to a single Holiday group.   Two new schedule durations have been added with the respective days selected that they would like the durations to activate on. On the 2 new durations, they added the Holiday group in the "Always Active On" area.   Product Line EcoStruxure Access Expert Environment Access Expert V3 Hosted Access Expert V3 Premise Cause Holiday and special date durations will activate on the holiday dates regardless of the day(s) of the week selected in the scheduled duration. The day(s) of week checkboxes in each duration is only used for setting a recurring weekly activation on those days and are not required for Holidays. For durations that will only be used during holidays, do not select any day(s) of the week. Resolution In this case, since you need two different durations during your holiday week, you will need two new durations but with different holiday groups for each duration. Set the M, W, and F duration as holiday group A and T, R for holiday group B. Now apply the Holiday Groups to the right dates via the Holidays Menu.
