Issue Should automatic updates be turned on for Continuum workstation? Are there certain known issues of updates that have caused problems with Continuum or Webclient? Product Line Andover Continuum Environment Continuum Cyberstation Continuum webClient Server Windows 10 Windows XP  Windows Vista Windows Server 2003 Windows Server 2008 Cause Microsoft Windows has an automatic update feature and frequently releases updates which can potentially affect Cyberstation and Webclient Server. Resolution Automatic updates should not be turned on for a Continuum or Webclient workstation. The Continuum compatibility matrix indicates Windows Operating Systems, Windows Service packs, SQL Server, .Net and Internet Explorer versions that were tested by Quality Assurance at the time of product release. Continuum Quality Assurance does not perform regression testing where new Microsoft updates are tested with Continuum products released in the past. Product Support recommends setting Windows updates to one of the other two options to allow for testing of Microsoft updates: Additional details can be found at: http://support.microsoft.com/kb/306525 Download updates for me, but let me choose when to install them Notify me but don't automatically download or install them   There are several specific updates that have caused issues with Cyberstation or Webclient. This is not a comprehensive list. Occasionally updates will break certain features and we discover this from our internal testing or from reports from partners or branches. Here is a list of some updates that have caused issues. KB835732-  Pinpoint 1.52 crashes when installed on a machine and you are accessing graphics from a network share. If you remove the hotfix the problem goes away.  This is the same hotfix that caused the SmartHeap out of Memory errors that was fixed with SP5 for 1.6.  KB828741- IIS (Webclient) machines without this patch may receive “Unable to establish a link to the remote Infinity services” Webclient 1.73 - Any patches that will install .Net Framework 2.0 will cause problems with webclient 1.73 since we don’t start using .Net 2.0 until webclient 1.74. KB911280 - this update blocks the acc.scp script from setting controller to PPP mode. This will a cause a Cyberstation using RAS controllers to not allow a connection. It will authenticate, but not connect. KB928366 – Webclient machines that use .Net 1.1(Listed on the compatibility matrix) will receive the error "Could not connect to server cause; type missing for member of type object _context id'. Could not create acwppserverproxy."  when opening web pinpoint graphics.  Remove this hotfix or upgrade to webclient 1.74 or greater. KB929969 – this hotfix does not require a reboot by Microsoft, but can cause the Cyberstation install to fail, if the install is performed before rebooting after the installation of the hotfix. See the Technical bulletin. KB968749 - SQL Express install fails on XML6 SP2 See SQL Express install fails on MSXML 6.

Issue Using the EGL, EGRL, EGLL5 which are obsolete Environment Vista Cause temperature/resistance data of EGRL, EGRLL, EGRL5 temperature sensors, or customer needs data to calibrate the sensors. Resolution EGL is replaced by the STD100-250 EGRL - STR100 EGLL  (2 thermistors) was not really replaced, as the average temp calc nowadays is done in the controller. The room version was named EGRLL. All these are for the Vista series.

Issue When using CIDR (Classless Inter Domain Routing) or Supernetting it is not always obvious what range of IP addresses can be used. Product Line EcoStruxure Building Operation Environment Device Administrator Building Commissioning Tool Cause When subnet masks with values other than 255 are used it is not always obvious what is the range of valid IP addresses allowed.  There is a need for an easy way to determine the range of valid IP addresses for the Subnet Mask being used. Resolution The IP address range can be calculated mathematically but the simplest method is to use a subnet calculator.  The website links below are both examples that will calculate the range of valid addresses for any specified subnet value.   http://www.subnet-calculator.com/cidr.php https://www.calculator.net/ip-subnet-calculator.html   Visit either of the websites for a CIDR / Supernet calculator, enter an IP addresses in the network along with a subnet mask and the calculator will provide the range of addresses that can be used within the subnet.   In addition to online calculators, a number of different subnet-calculator programs are available for Android, Apple and Windows Smartphones.  

Issue Controllers underneath a LonWorks Interface are going offline, or values are taking long periods of time to update. Product Line EcoStruxure Building Operation Environment Building Operation Workstation Cause There could be a number of causes for Lon communication problems including running the communication wire near high voltage, the Lon is shorted out, or loose terminations. Resolution In EcoStruxure Building Operation (EBO) Workstation you can use the Diagnostics tab under each controller to help troubleshoot the communication issue. From here you can monitor the device state, packet errors, transaction timeouts, receive transaction full errors, lost messages, missed messages, last reset case, and the last error logged. To access the Diagnostics tab, select the controller in the System Tree, and click the Variables tab. Then click the Diagnostics tab on the right side of the screen. Here you will find the different device statuses and statistics. The Packet errors can be used to help identify controllers that are having severe problems and may need the communication wire to be physically checked. In order to test the Packet errors, first you will want to clear the current packet error count. You can do this by right clicking on the controller and selecting Advanced -> Clear Status. This will set the packet error count back to zero and now you can click refresh to monitor how fast the errors are building up. If this number is climbing quickly then there may be a physical layer communication problem. If a lot of packet errors is found, the next step in the investigation will be a deeper analysis of the Lon network, using, for example, a Lon Protocol Analyzer (LPA). Refer to the Knowledge Base Article Troubleshooting LON Network Communication.

Issue There is a need for a single Compatibility Matrix that shows EBO, PME, Energy Expert and relevant software versions all in the same location.   Product Line EcoStruxure Building Operation, Other   Environment EcoStruxure Energy Expert (formerly Power Manager) ETL tool Cause Energy Expert version compatibility information is currently available but is stored in many different places such as release notes and online documentation, rather than one single matrix.   Resolution The full ETL for EBO compatibility matrix is shown in the following table. Energy Expert  PME EBO ETL Integration Utility .NET Framework Power Manager 1.0 7.2.3 1.6.1 3 1.0.14304.2 4.5 Power Manager 1.1 8 1.6.1  1.7.1 4.1 1.0.15306.1 4.5 Power Manager 1.2 8.1 1.6.1  1.7.1  1.8.1 4.3 2.1.16081.1 4.6 Power Manager 1.3 8.2 1.8.1 1.9.x  4.6 2.2.17056.2 4.6 Energy expert 2.0 9 2 5 3.0.18215.3 4.6 Energy expert 3.0 2020 3.0 3.1 6 3.1.19319.1 4.6 Not commercialized  - (n/a) 2021 3.2.3 6 Integrated - (n/a) 4.8 Not commercialised - (n/a) 2022 4.0.2/2022 6 Integrated - (n/a) 4.8 Not commercialised - (n/a) 2023 5.0/2023 6 Integrated - (n/a) 4.8   Great care must be taken when choosing the correct version of ETL to use when integrating Energy Expert and EBO, as there are actually two families of ETL in production.  One ETL designed and tested for PME use only and ETL for EBO designed and tested with an EBO Extract Task specifically for integrating the two systems.  (For example, a version of ETL 4.7 exists, but this is not ETL for EBO and therefore does NOT contain an EBO Extract Task, even though it is a valid version of ETL for the Power Community) New PME 2023 now offers EWS Client 1.2 which can be used to transfer data from EBO to PME instead of ETL.  The merits for and against using this new EWS Client rather than ETL are discussed at length in the PME 2023 System Guide

Issue After 9 straight failed Workstation login attempts the SmartX Controller will be locked out.

Issue Receive error "Property value out of range" when creating a BACnet interface on the Enterprise Server   Following problems after upgrading SmartStruxure servers to 1.5: Attaching an Automation Server to or detaching it from an Enterprise Server will fail with “Property value out of range” error. Changes to the ~/System/Interface Manager/BACnet fail to be propagated lead-shadow functions through to the child servers. Automation Server controllers dropping offline following an upgrade to 1.5 (BACnet command priority related  also may see numerous "Changeset Rollback errors") Product Line StruxureWare Building Operation 1.1, 1.2, 1.4, 1.5 and above Environment Enterprise Server (ES) BACnet IP Interface Windows XP, Windows 7 and Windows Server 2008 R2 Cause Their may be various items that generate this error, checking the Enterprise Server (ES) system log in the Software Administrator may assist in pin pointing the error.  If you see an error that ends with ~/BACnet Interface/IP Network, then this error is generated when their is no valid IP Network.  For SmartStruxure 1.5 or above or planning to upgrade from 1.4 to 1.5 (and above)  This issue only occurs if a BACnet interface is used and the site has changed the BACnet "Default Priority Level" from the default value of 16, to 8 or a smaller numeric value in the Automation Server while running in V1.4. The "Property value out of range" message relates to the new Force priority level in 1.5 and the Default priority level in 1.4.1 being mismatched. Resolution The ES must be connected to an IP network. To resolve this error follow these steps: Close all Workstations (if running) Connect the Enterprise Server to a valid IP network (with a valid IP address). Stop and Restart the Enterprise Server service through the Software Administrator application. This should now allow the BACnet Interface to be created successfully For SmartStruxure 1.5 or above or planning to upgrade from 1.4 to 1.5 (and above) Please refer to TPA-SBO-14-0005.00 Before upgrading to 1.5 make sure the "Default Priority Level" within the Automation Server is set to 9 or higher.  If the system has been upgraded with the incorrect values, then: If the site uses single servers, or the ES/AS communication still operates correctly, then this can be corrected by changing the setting in both the AS and the ES to a value of 9 or higher.   If after upgrading a multi server configuration and the AS does not stay online, then a Hotfix can be used fix the problem using the following steps: Apply the hot fix #1.5.0.4301; available from Product Support Services Fix the multi-server (by detaching/re-attaching the servers) Correct the two properties (AS and ES). WARNING: It is essential for any BACnet system at 1.5 or later that the "Default Priority Level" must have a larger numeric value than the "Force Priority Level, otherwise some BACnet functions may not behave as expected. Note: This also applies even if the hot fix has been installed. The effects of not setting the Default above the Force Priority level are: If Force Priority Level is equal to the Default Priority Level: Changing the Value of a BACnet value or a BACnet output object will cause the Value to appear Forced. This applies to the BACnet objects in both SmartStruxure servers and those in 3rd party BACnet devices.   If Force Priority Level has a larger numeric value than the Default Priority Level: Changing the Value of objects mentioned above will cause the Priority Override icon overlay to be turned on next to the Value property in the WorkStation’s property grid.

Issue BACnet devices not found but are visible in other third party BACnet applications An update may cause devices to go offline Product Line EcoStruxure Building Operation Environment BACnet IP Network Building Operation EnterpriseServer Building Operation Automation Server (AS, AS-P, AS-B) Cause According to BACnet routing rules, each BACnet Device should have a unique BACnet Instance ID and each BACnet Network should have a unique BACnet Network ID  When a BACnet interface is created on an EBO Server, a BACnet IP network is created with default Network ID of 1. This is a local Network address and in not published on the network, it is therefore not a problem if this is duplicated with other EBO Servers. On many site this will remain at 1 for multiple EBO servers with no problems. If a third party BACnet device uses a published Network ID that is identical to the EBO local Network ID, then it will be ignored. There will be a "Duplicate of local network"  System Alarm and line similar to below in the trace log "nsp.pin.BACnet Device <device name>claims to be router to Network #1234 but that is a local network (BACnetMain)" Resolution If the EBO Server is not finding a BACnet device on a different network type (via BACnet routing like MSTP or virtual IP) then it could be the Network ID is identical to the local EBO Server Network ID. If this is the case, then simply change the EBO local Network ID and retest. BACnet Devices on the same IP network, including those on different IP subnets and linked via BBMD or Foreign Devices are not BACnet routed and therefore will not have this issue (no BACnet Network ID route is involved) Some earlier versions of EBO did not ignore these duplicate Network IDs, thus when up grading some devices could go offline. The workaround would be the same. The correction to the BACnet operation occurred in v1.9.3 and v2.0.2

Product Line Andover Continuum Environment Continuum 1.xx SQL 7 SQL 2000 SQL 2005 Cause Stand Alone Continuum Databases use Microsoft MSDE and SQL Express databases which have size limitations. Once these databases reach full capacity they will need to have data truncated from tables to try and reduce the size of the database.

Issue Controllers may leave their network and join another if a nearby network has an identical "Extended network ID", "Channel" or "PAN ID" Product Line EcoStruxure Building Expert Environment SmartStruxure Lite Multi-Purpose Manager SE8xxx Room controller SE8000 Series SER8300, SE8300, SE8350 Ex. Viconics branding VT8000 Series Cause Conflict in zigbee networks (Same "Channel", same "PAN ID" or Same "Extended Network ID") Resolution Before deployment, and in order to ensure having a reliable ZigBee network, one has to be aware of the best practices and the limitations of RF signals. Here are some key points to be considered Network Conflicts: Always change your Extended Network ID from the factory default. The best thing is to use a naming convention that makes sense. One suggestion would be to use "SSLLITxx," where "xx" is replaced by the floor the network is on. For example, floor 5 would be "SSLLIT05." If you have multiple networks on the same floor, adding a letter code helps denote them. For example, if there were 2 networks on floor 5, "SSLLI05A" and "SSLLI05B" can be used. Note: In Firmware 2.20.1, the ZigBee Extended Network ID parameter is set by default to a unique string based on the serial number of the MPM. This will eliminate the possibility of having duplicate Extended ID's in a new deployment. For existing installations, the Extended Network ID will remain unchanged if upgrading from a previous version.   Alternating Channels: Alternating channels between network will minimize interference ensure stability. For example, for a 5-story building, alternate between channels 20, 25, 20, 25, 20. Tx Power Upgrade: The default value for "Tx Power" is 5dBm which was designed in order to meet various regulations in certain countries (Europe). However, the "Tx Power" can be increased to 18dBm in other regions of the world (North America) to boost the transmission power of the MPM.   Interference: There are different types of interference when a wireless signal travels through a given space: Physical objects: The number of walls the wireless signal can pass through is determined by the density of the materials used in a building's construction. Concrete and steel walls are difficult for a signal to pass through. These structures will weaken or at times completely prevent wireless signals. Also, the presence of individuals or water will diminish the signal due to the water's ability to absorb the signal. 2.4Ghz Frequency Interference: Cordless Phone - operates on the same frequency as the ZigBee and can cause a significant decrease in performance. Microwave Oven - operates by emitting a very high power signal in the 2.4GHz band. Often emits a very "dirty" signal across the entire 2.4GHz band. Wireless Routers - Wireless Wi-Fi Networks that share the same channel will have a negative effect on ZigBee network performance. Distance: To ensure reliable communications, a suitable distance between two devices has to be calculated before installation. The distance depends on three factors; transmitter power, sensitivity of the receiver and the propagation path loss. The latter is dependent on the number of walls/physical objects obstructing the signal. Locations: The physical location where a router or coordinator is placed also has an impact on the signal. Place the devices in higher ground to reduce the impact of physical objects. Route Redundancy: It is critical that the signal has multiple routes to hop from one device to the other, from one edge of the network to the opposite edge. (See example in images below)

Issue Existing SIM-MTECH communicates with a McQuay OPM (Open Protocol Master) and McQuay controllers under it. Can an AS-P replace the SIM-MTECH?

Issue What is the limit of how many devices a BACnet controller can know about (Known devices) and what does that mean. Product Line Andover Continuum Environment BACnet bCX bCX4040 Cause More details required about Known devices Resolution The known device limit of a Continuum Ethernet level BACnet controller is 255 and for a B3 level MSTP controller it is 32. This limit means is if a controller needs to either subscribe to a COV from another controller or deliver alarms (Event notifications) to a workstation, that each one of these target devices is a known device. So, for example, if a b3 controller is subscribing to COV's from 30 other controllers and needs to deliver alarms to 3 WorkStations, it would require 33 known devices and the last request for a target device would fail. If a Controller is making 30 COV Subscriptions from one a single controller that would only count as 1 known device. This limit does not apply to the number of other controllers which a COV exporter can deliver COV data to. For example, if a controller had a global point (OAT) that 50 other controllers needed to subscribe to, this is allowed because each COV subscription has within it the target controller's address information and does not use the known device limit. There are two cautions that must be considered. Refer to What are the differences between Standard Continuum Import/Export and Continuum BACnet COV?. Each COV subscription in an exporting controller takes away user memory. Each subscription uses approximately 56 Bytes of user memory. So the limit of how many other devices can subscribe COV's in an individual controller is limited by free memory in the exporting controller. NOTE: To reset  the known devices following a change in the Controllers that will effect the number of known devices, the controller needs to be reloaded.

Issue What is throttling range? Product Line TAC I/A Series Environment I/A Series controllers Cause Setting a proper throttling range will allow for more accurate control of external actuators and devices. Resolution Throttling range is the amount of change in the process variable that is necessary to cause the controller output to change from 0 to 100%. The controller output may be 4-20mA, a voltage range, or pressure range.
