Issue Is it a problem in StruxureWare Building Operation to start many trend logs at the same time? Environment StruxureWare Building Operation version 1.3 Cause When starting several trend logs at the same time the Servers will try to read all the logged values at the same moment which is causing a big load on the system. Resolution Starting several trends at the same time should not have a big impact on the rest of the system, and our internal thread management shall ensure that no logs are missed. But it could cause a big load on the field bus and field devices so this is something to consider.

Issue There's a need to understand how COV subscriptions are established and re-established when a controller goes offline and comes back online Environment StruxureWare Building Operation b3s Cause COV subscriptions get established with PE programming and with bindings Resolution The time to live for the subscription is 5 hours and gets checked every 5 minutes. If the b3 (client) goes offline eventually the subscriber server will stop the subscription after it sends out 4 messages every 3 seconds. If the acknowledge that the subscription isn’t received by the server device then it stops the subscription. The client subscriber is the one that determines the initiation of the subscription, so in this case once the b3 resets, either warm start or cool start and the program runs then the subscription would start again. A cold start would not start the subscription. If the target device goes offline, then it will be searched for with the ‘who-is’ service, and when it comes back online (the device replies with ‘I-am’), the COV subscription will be reestablished. A binding will also attempt to setup a COV subscription.  If the target device goes offline, then it will be searched for with the ‘who-is’ service, and when it comes back online (the device replies with ‘I-am’), the COV subscription will be reestablished.

Issue An existing Niagara G3 server is being replaced with new hardware.  The new server is being configured while the existing server continues to operate the station.  A replacement license has been provided for the new server with a new hostId.  The license for the existing server has been de-activated by Tridium.  Will the existing server continue to function even though its license has been de-activated?  Note:  The existing server has an Internet connection. Environment Niagara G3 Cause PC hardware replacement Resolution The existing server will continue to run the station.  The license remains active as long as there is no web-based license update performed.

Issue How to estimate the thermal load (BTU/hr) that your controllers and equipment will produce. Environment All electrical equipment. Cause Need to know what the thermal load of our equipment will be for calculating air conditioning capacity. Not all of our equipment has this information provided in data sheets. Resolution It is possible to calculate the thermal load based on the power consumption of each device. See here for an online calculator. You can calculate the BTU/hr using the following formula. BTU/hr = Power (W) * 3.1412141633 As an example, looking at the Continuum AC-1 I/O module's datasheet, we see that it consumes 2.6W without the attached reader (you would need to add the power from the reader as well if it is being powered by the AC-1). Which gives us; AC-1 = 2.6W * 3.412141633 = 8.87 BTU/hr Use this same calculation for any other devices that you require the thermal load for.

Issue  If JAVA 7 update 25 is installed, web browser users who login with a Workbench profile (which uses JAVA applets) are affected. The web applet is prevented from being started, and the browser appears to stop loading the Niagara user interface. Environment I/A Series G3, all versions All browsers may be affected JAVA 7 update 25 Cause Oracle has just released JAVA 7 update 25 which appears to cause the I/A Series Niagara web applet to fail. This issue may affect your customers who accept the default automatic JAVA upgrade. Resolution See TPA-IA-13-0007.02 for details. Patches are available for the following builds: 3.5.39 with security patches 3.6.47 with security patches 3.6.305 3.7.46 Download and install wbapplet.jar for all 3.5 and 3.6 stations or web.jar for 3.7 stations. Update baja.jar and fox.jar for all stations.
