Issue How to order more LonMaker credits in order to commission more devices. Product Line TAC IA Series, TAC Vista Environment LonMaker LNS Cause There are two types of credits: Product specific credits like LonMaker and NL credits LNS credits   LNS LNS credits are assigned to the PC and when they reach zero, the LNS Server license goes into deficit mode. After 14 days the deficit mode will expire, at which time no LNS tools will be able to be used on that PC. To reverse the lockout, enough LNS credits must be ordered to cover the deficit and any additional nodes that need to be commissioned. Backing up, sharing, and restoring LNS databases can sometimes corrupt these LNS credits, which then prohibits you from launching any LNS plug-ins. For more help with corrupt LNS credits see Corrupted LNS Credits. LonMaker LonMaker credits are assigned to the PC. Both LNS and LonMaker credits are required, however when commissioning devices in LonMaker, LonMaker credits are consumed but LNS credits are not. Even though LNS credits are not consumed in LonMaker they are still necessary because certain LNS applications (i.e. TAC Vista System Plug-in) require them to operate. NL220 Each time a node is commissioned in NL220 it requires a NL credit and a LNS credit. NL credits are assigned to the NL220 dongle and can be used on other PCs in "MOVED" mode. LNS credits are also necessary in NL220 to operate certain LNS applications such as the TAC Vista System Plug-in.   To order more Echelon LNS credits see Ordering more LNS credits. To order more Newron NL220 credits see Ordering more Newron NL220 credits.

Issue Communications with other Lon network devices are lost after the IC-Lon/IC3-Lon has cold-started. Product Line Satchwell Sigma Environment Sigma IC-Lon Integration controllers IC3-Lon Integration controllers Cause The controller has been cold-started either manually or through the automatic process. Resolution The final part of the engineering process of the IC-Lon/IC3-Lon, is for the file named NVConfig.bin to be uploaded from the IC-Lon/IC3-Lon to the Sigma server. If this file is not uploaded, then the IC-Lon/IC3-Lon reverts to its non-bound state. The NVConfig.bin file contains information about the Lon bindings and is modified during the binding process when using LonMaker. To upload the NVConfig.bin, carry out the following: Open "System Diagnostics"  on the Sigma server. Select the correct controller number. From the "Options" menu select "Upload Files" and NVConfig.bin This file will now be uploaded and overwrite the existing file in the controller folder, and therefore when the controller next cold-starts, the correct file will be downloaded to it. For more information on the Engineering process of an IC-Lon/IC3-Lon, please click here.   The Sigma system is now out of its support period, consideration should be given to transitioning or upgrading to SpaceLogic - EcoStruxure Building Operation.

Issue How does the import/export (IE) system work in the Continuum controllers? Product Line Andover Continuum Environment CyberStation All CXs All i2s, Infinet Controllers Cause Continuum controllers implement an Import/Export strategy in order to minimize network traffic when accessing the value of a point in a remote controller. The principle is that the value of a controller point that is referenced by other controllers on the network only needs to be sent out when it changes, much like the BACnet COV which stands for Change Of Value. The two parties involved in the IE transaction are the controller that owns the point (the owner) and the controller(s) referencing the point's value (the subscribers), a second CX controller may also be involved and acting as a router when a value is imported/exported from/to a remote field device under a remote CX. Resolution Read more in the attached document, Understanding Continuum IE System.  See how to correct Import Export tables KBA

Issue What are CZT, CXT, CXR Controllers? Why are CZT, CXT, CXR Controllers used? What is Proportional, Integral Action and Derivative control. Why does a controller deliver different pulse lengths to the valve and not drive it fully open or closed? What is Pb, IA, PID? Environment CZT CXT CXR DC1100 DC1400 Proportional, Integral Action, Derivative, Pb, IA, PID Cause What do these controllers do and what are their applications? What is Proportional, Integral Action and Derivative control. Why does a controller deliver different pulse lengths to the valve and not drive it fully open or closed? What is Pb, IA, PID? Why is a 0-10V Signal used? Why is a 3 point control / Open Closed actuator used? Resolution Proportional Controllers are used in applications where there are long time lags e.g. room control, return air control, storage calorifier (HWS). Where the controlling sensor is a medium to long distance from the heat/cooling source. An example of a proportional controller is the Satchwell CZT. Integral action controllers are used in applications where there are short time lags e.g. supply air control, frost coil control, non-storage calorifiers. Where the controlling sensor is a short distance from the heat/cooling source. An example of a integral controller is the Satchwell CXT or the CXR. The CXR is a controller where the supply air is controlled, but the setpoint is reset by the return air or space temperature, therefore the time lag is short. Other controllers that fall into this category are the DC1100, DC1400 again the controlling sensor (mixed flow temp) is located a short distance from the heat source.  The term proportional band (Pb) is where the valve is moved to a position proportional to the deviation from setpoint. 0-10V modulating actuators are generally used on these controllers. The term integral action (Ia) is where the valve is moved at a rate according to the deviation from setpoint i.e. the valve is given longer pulses the further away from setpoint, shorter pulses as it gets closer. 3 point control/pulsed pair/open-close actuators are generally used on these controllers. Further to proportional controllers, inherent offset (the setpoint is never quite reached) can be an issue. Integral action can be applied to remove this offset. These controllers are primarily proportional, but integral action can be found on them and is applied. Hence the term PI or PI controller. Derivative control is generally only found on BMS controllers and is used occasionally with PI control, hence the term PID. Here the derivative action moves the valve proportionally to the change from setpoint. It is complex and is rarely used. Further detail about CSC controllers can be found here.

Issue A method of offline database engineering is needed for SmartStruxure.  Product Line EcoStruxure Building Operation Environment StruxureWare Building Operation Project Configuration Server (PCS) Cause System integrator wants to engineering expansions and new automation to the site offline. What is the procedure if the client already has the ES and AS devices onsite, but wants to engineer offsite? If not can we only add one AS per project then restore / deploy just the AS and how is point referencing managed on bindings to the original site server? Resolution Beginning with the release 1.5 version of Project Configuration Server(PCS) is a 'deploy once' version, meaning that it allows you to make the first configuration offline. It is a full deployment meaning it may only be the ES or AS or the ES with AS connected. There are no partial deployments with bindings intact with existing servers. For deployment to include bindings between the ES and AS or other devices, they must be added to the initial deployment, which will overwrite existing configuration. Note: the 64 AS limit is a performance issue. 64 fully loaded AS in a project takes a long time to open. Once a server in the PCS project is deployed on site, you cannot deploy it again without manually erasing the database in the online server using the Device Administrator or uninstall and re-install the Enterprise server. Consider the following scenario where an office wishes to use the PCS on a project with staged installation and an ES with 15 AS: Create the ES and all 15 AS in my project. You may not have the project’s communication information because none of the final IP addresses are available. So put them in with 192.168.1.x Configure all of what is needed in 5 of the AS (AS1 – AS5). Configure all of the IO and other objects in another 5 AS (AS6 – AS10) Do nothing with the last 5 AS (AS11-AS15). Create some read references in some of my programs in AS1-AS5 that are referencing objects from AS6 – AS15. Create extended trends and alarms categories at the ES. Create alarms in AS1 - AS5 that use the alarm categories. Go to the site and deploy AS 1 to AS5 (after modifying the communication parameters for those 5 so that you can bring them on line.) The alarm categories will be deployed to the AS in spite of the fact that the PCS would have had them configured as lead and shadows from the ES, which was not deployed. However, there would likely be an offline alarm generated because there was no ES and there might also be a lead/shadow alarm. The alarms will be correctly configured, however, and operational. The references to the objects from AS6 – AS15 will appear as unresolved in the AS1-AS5 reference managers. Go back to the office and finish everything needed in AS6 – AS10 Create graphics at the ES referencing objects from all 15 AS. Create trend charts showing log data from all AS. Create users, domains, workspaces, etc. Go back to the site and adjust the communication parameters for all the remaining 10 AS and for the ES Deploy AS6 - AS10 and the ES. Initially, the AS1-AS5 have empty/wrong communication settings to the ES. It requires a manual “Repair Com-settings” from the user logged on to ES (at the site). When the Com-settings are ok, then the bindings from AS1- AS5 to AS6-AS10 will be resolved after a few minutes. When the Communication settings in AS1-AS5 for the ES are correct, the synchronization for lead/shadow relationships starts updating the alarm categories that we discussed in step 8a. The graphics in the ES will have resolved bindings for objects from AS1 – AS10, but unresolved bindings from AS11-AS15. In fact, they will be resolved to AS1-AS5 even if you haven't corrected the Com-settings in AS1-AS5. The ES knows all the AS. Go back to the office and finish up my work on AS11-AS15. Part of this process is the creation of programs that reference objects in AS1 – AS10. Go to the site and deploy AS11 – AS15. All of the read references to objects from AS1 – AS10 will automatically fix up once the Com-settings for the ES in AS11-AS15 are correct. It might, however,  take a few minutes. All of the references in the ES graphics for AS will be operational.   Further information can be found on Building Operation WebHelp.

Issue Graphics are not displayed via the WebStation. Product Line EcoStruxure Building Operation Environment EcoStruxure Building Operation WebStation Graphics Trends Display issues Long hyphen # character Cause When a graphic is requested on a Building Operation Webstation, it is not displayed. The display will remain blank. Resolution Try the following steps below to correct the WebStation loading issue. Check the file size of the graphic page. If the TGML graphic size is too large it can have issues loading in WebStation. Majority of the times it is due to an image that is too large such as a floor plan.  If a graphic, or trend chart object, is created through a EcoStruxure Building Operation WorkStation and its name contains a "long hyphen", the graphic and trend chart objects cannot be viewed through WebStation. The long hyphen is not a supported character. When creating object names do not use the long hyphen (—) only use the short hyphen if required (-) If the version being used is 1.3, upgrading to 1.4.1x may resolve the issue. Check the name of the AS, an unsupported character may have been used e.g.#, to resolve, remove the character.

Issue Changing the name of a folder under which there is an active alarm, causes an incorrect "Source" path in the alarm message Product Line EcoStruxure Building Operation Environment Building Operation Workstation version 1.8 or earlier Cause If a folder name is changed it will be correctly updated, but if an active alarm is located  in its sub-folders , then the alarm source path will not be updated. Initial alarm before the folder name is changed, notice the source ...... FF IV/Trendloggar ...... The alarm after the folder name has been changed FF IV TEST, the / between FF IV TEST and Trendloggar is missing. If the alarm has not been acknowledged, and clears a second entry for the alarm is displayed in the alarm view. Resolution This is fixed in SBO/EBO 1.9 and later versions.   For versions 1.8 or earlier: Before updating a EcoStuxure Building Operation(EBO) folder name, check to see if there are any active alarms with a source path that use this folder. If there are, try to clear these alarms. If a EBO folder name has been changed and there are alarms in the alarm view which cannot be cleared, then use the "Recheck" command to clear them.

Issue Where to begin troubleshooting Ethernet (TCP/IP) communication problems with a NPR Product Line TAC INET Environment I/NET NetPlus Router (NPR) Model Series 2000 Cause Possible Causes: Ethernet Communication is down Ethernet Port is closed Device is configured incorrectly Device failure Resolution Gather detailed information about exactly what is happening Ethernet Communication is down Using the command prompt ping the devices IP and trace its route. "ping xxx.xxx.xxx.xxx" and "tracert xxx.xxx.xxx.xxx" Watch to see if the Domain server prints out the correct Host name. If the device is shows as offline there may be an error with Firewall settings or Ethernet communication at the Host Workstation Disconnect the Ethernet cable from the Device and plug it into a laptop. See if you are on the network. Ethernet Port Is closed If the above process shows that Ethernet communication between the Workstation and Router is valid, you may have port closed. Use a crossover cable to connect a laptop to the device and see if you can connect to a controller ON THAT LINK in I/NET. Look for live values in Controller Summary. If you are able to do this, and you are able to show that Ethernet communication between the 2 devices is working then you most likely have a firewall that is block the UDP port 50069 Contact the building IT department to assist in rectifying this problem. Device is configured incorrectly If, in the above process, you were unable to connect to I/NET while direct connected to the Router via an Ethernet crossover cable, the device may be configured incorrectly Open the active I/NET configuration Profile Ensure that TCP/IP is enabled Add the Router’s IP address to the Reference Host Table Restart the I/O server Check communication Alternatively you can connect to the router via I/NET Direct Connect configuration profile. Refer to Troubleshoot an NPR problem with Windows Telnet utility on how to do this and check that the IP Address and details are set correctly. Communication should be restored. Device failure Try to reset the NPR: Remove the NPR cover. Depress the center tab of the I/DISC slot and hold it down. Next press the reset button on the front of the unit and hold for 10 seconds. Release the reset button and then release the center tab. Two LEDs should display steadily. Next depress the center tab and hold it down. Press the reset button on the front of the unit and hold for 10 seconds. Release the center tab and reset button simultaneously. The LEDs should display steadily. The NPR unit should now be ready for a software restore. Download and install the latest system file for the NPR. Configure the I/NET communication in your active Configuration Profile. If you not able to successfully update the firmware in the NPR then it is likely that the device is faulty and may require repair or replacement.  The current replacement for the Series 2000 NPR is the Xenta 527-NPR. Other Troubleshooting Steps See if the communication error shows up on multiple computers and if possible multiple locations. There may be an error with Firewall settings or Ethernet communication that only effects part of a large system Host Workstation Use a different Ethernet port to connect the NPR or workstation too. Direct connect to a controller on the controller LAN via TAP and see if any stations are offline. It is theoretically possible that some form of electrical failure on the controller LAN has caused the NPR to appear offline. If you are unable to see the entire controller LAN from anyone one device, you should troubleshoot Controller LAN communication. Contact Product Support with your findings.

Issue A BACnet Schedule is working but not changing the point it is controlling   Product Line Andover Continuum   Environment CyberStation Schedules BACnet command priority Cause A BACnet Schedule will by default, write to a BACnet point at a certain command priority level.  However if that BACnet point is also being commanded by a higher command priority then the present value of the point will not change according to the Schedule.   Resolution Example: A BACnet Binary value is created and the operator wishes to set the value to Off. If the value is set by a Manual Operator then by default this will command the point to Off at command priority 10. If a Schedule is then created and the point is attached to that Schedule, because a Schedule's default priority is 16, at the configured time, when the Schedule tries to change the point to On it can only command that point at command priority 16 The point itself always obeys the highest command priority which in this case is command priority 10 so the value stays Off.   To correct the above scenario there are two main options: Edit the Command Priority Tab of the BACnet Point and perform a Relinquish at command priority 10 to clear out that command, at which point the BACnet object will then defer to the next highest command priority (which in this case would be command priority 16) Edit the Schedule and change the command priority on the Schedule configuration page to an appropriately higher priority such as command priority 10.     NB. In cases where a point is written to at the same command priority as another object then the point will be controlled by whichever object wrote last...

Issue What actions should be taken if the alarm "Missing response from server" appears in the Enterprise Server? Product Line EcoStruxure Building Operation Environment EcoStruxure Building Operation 2.0 and later versions Cause ES/EC is waiting for a response from another server(most likely AS/AS-P/AS-B) for more than 120 minutes. Might lead to deadlock and starvation of resources. Can potentially replicate through the system and affect other servers. Examples of problems that could occur are: Values in graphics that reside in a sub server (most likely AS/AS-P or AS-B) are not updating.  Not possible to login to ES/EC Resolution Acknowledge the alarm "Missing response from Server" If not triggered again after 15 minutes then it is not a problem anymore (or at least less likely) If triggered, then continue below In the Alarm view, locate which server the alarm "Missing response from Server" comes from and log in directly to that server. Is the server responding? If not, restart the server. If it is responding, unplug the network cable to the server for a few minutes. Plugin the cable again and acknowledge the alarm. If it triggers again after 15 minutes, then Take 2 core dumps on the server (for investigation of why this problem occurred). Contact your local Product Support contact for instructions on how to do that. Restart the server (should fix the problem)

Issue How to get the XIF file of Xenta free programmable controllers?

Resolution Open the preprogrammed Menta file in the Menta Editor.  Note: If you are opening the file directly from the Vista database, it will first need to be saved to the local harddrive before generating an XIF. Go to Options > Simulate (or press F12) Go to Commands > Generate An XIF file with the same name as the .MTA file will be generated in the same location on the harddrive as the. MTA.   Alternatively, if you are connected live to the controller, you can also generate an XIF by connecting live: Open the preprogrammed Menta file in the Menta Editor. Connect the Xenta free programmable controller to the computer with a RS232 to USB cable. For details please refer to Downloading a Xenta Device Using Direct Connection to Menta Programming Tool. Go to Options->Simulate (F12), and select connect. A XIF file will automatically generated under the same folder that the Menta file is saved. NOTE: in order for third party system to be able to view points in Menta, those points need to be set as SNVTs.
