Issue How can an alarmed point be configured to close the currently active graphic before launching the graphic points alarm graphic. Environment Pinpoint Alarm Graphic Cause Using the Display Graphic action on an Event View, it is necessary to have only one alarm graphic open at a time. Resolution Event Notifications provide for the launching of specific graphic panels when a point goes into alarm. No provision exists for closing having this alarm close the currently active graphic panel before it' launches its graphic.

Issue A new utility is being used to record log data and store it in the "cloud". It has been requested that the log data have timestamps every 15 minutes synchronized to the hour.  Environment Sigma Trend Log Log data Log set Logging Timestamp Cause There is no mechanism with Sigma to specify when a log set starts to process the logging data. When set to log at timed intervals the log bucket file is downloaded to the controller and processed. The timed interval then starts from that time. There have been some requests for data to be synchronized to the hour with 15 minute log intervals. Resolution There is a engineering workaround to make Sigma do this. A prog point will be needed for every value that is required to be logged. The text is below. 10 XFlo = POINT 0|41 - Object to be logged 20 IF MINUTE = 0 OR MINUTE = 15 OR MINUTE = 30 OR MINUTE = 45 THEN GOTO 40 30 RETURN VIA TEXT 92 VALUE YFlo 40 IF SECOND DOWN THEN GOTO 60 50 RETURN VIA TEXT 92 VALUE YFlo 60 YFlo = XFlo 70 RETURN VIA TEXT 92 VALUE YFlo Then setup the log set with the log data set to "change of value".

Issue What grade of stainless steel is used in the Satchwell DWA range of sensor pockets Environment Sensor Pockets DWA Satchwell Cause Customer requires assurance that the stainless steel pockets are the correct grade. Resolution The DWA (Satchwell range) pockets that we sell are made from 316Ti steel. We use 316Ti rather than the 316L because of elevated temperature mechanical strength, pitting corrosion resistance, mechanical polishing and weldability.

Issue What mains actuator can be used with a VTRA rotary valve? Environment VTRA Actuator Mains Cause Existing actuator has failed and is no longer available. Resolution The replacement actuator and linkage are required; M9B-230 actuator - 860-1020-000 Linkage - 860-0990-000

Issue ACX7xx (ACX701, ACX781) swipe of card that is not in DB results in reader LED blinking slowly for over a minute. Then an access events 'No response from access server' is logged in the access event log. Product Line Andover Continuum Environment CyberStation ACX701 ACX781 Cause AccessServer system variable set to an incorrect value. For example, a value of 1 will cause the ACX to attempt a remote validation to the controller with ACCNetId of 1, whether it exists or not. Resolution Set the AccessServer to 0 (zero) if not remote validation is desired, or set it to the ID of the Primary Access Server workstation. NOTE: The old ACXs require a reset when the value of AccessServer is changed. After making the changes reload the controller.

Issue Can Continuum Extended logging be configured on point with a Log Interval of less that 60 seconds. Environment Continuum CyberStation Extended Logging Cause The project spec calls for extended logging of point with a 5 second log interval. Resolution While it is possible to configure extended logging points for intervals of 1 to 59 seconds, this is not recommended.  Continuum should notify the operator that this is not recommended when the point is configured.

Issue It appears the Dynamic DEMUX object in R2 - LonWorks jar - Conversions folder is not setting the output bits incorrectly for some SNVT_State values? Environment R2, all versions Cause Third party definition of the SNVT_State bits. Resolution The dynamicDEMUX object takes a "SNVT_State" value in and breaks it into representative output bits 0 to 15.  This object assigns the bits from bit0 to bit15 with bit0 on the left and counting left to right.  For example a SNVT_State value of 1000 hex is 1000000000000000 in binary, therefore the DEMUX object would show bit0 on.  Some third party manufacturers define their SNVT_State bits starting with bit15 on the left and counting down left to right ,so in this example their documentation would indicate bit15 should be on .  Once this is understood the DEMUX output bits can be interpreted correctly.

Issue ACX5740 appears normal when powered up but as soon as a card reader is wired, the card reader is continuously in "power up" sequence whether reader voltage is set to 5V or 12V. The reader is designed for either of these voltages. Environment ACX5740, ACX5720 Cause The ACX5740 power input was miswired at the power supply. It was being powered from the battery charging circuit instead of the DC output of the power supply. The charging circuit apparently uses a pulsing 24V DC voltage designed to recharge a battery. When powering the ACX (designed  to accept 10-28VDC) it looks normal at first. However, the pulsing of the reader power output is not within the card reader input voltage specs.  Resolution The ACX5740 power was miswired. It was being powered from the battery charging circuit instead of the DC output of the power supply. Proper wiring to the power supply DC output fixed the issue.

Issue Every b3 wireless controller can communicate with BCX1 separately, but when there is a b3 wireless controller is online, the other controller can't be brought  online, the online controller must be powered off or remove the adapter, otherwise, the others will never be online. Environment Continuum Cyberstation BCX1 wireless B3 wireless Cause If the wireless adapter and wired RS485 was connected, this issue will happen. Resolution Remove the wired RS485 connector from the controller or disconnect the MS/TP bus, From the Comm2 port of BCX1, click "learn", All the b3 wireless controller will come online quickly

Issue Which sensors can be used if mounted directly into the pipe, without pockets? Environment Kamstrup heat cool flow meters Cause In some applications, sensors mounted directly into the pipe, without using pocket, is requested. Resolution Unfortunately, we do only recommend the sensors that are included with the meter package, or ordered as an option with longer cords. All are requiring pockets for proper mounting. 

Issue An installation has a DMS-3500 with an Ethernet NIM (Network Interface Module) and some MicroSmart controllers.  As part of a regular maintenance visit, a database backup is done.  What is considered a complete backup including the NIM's settings? Environment DMS OPRIF 11.4 & 11.6 Cause Database changes requiring a backup in the event a re-install is required Resolution A complete DMS database backup typically involves two steps:  a backup of the DMS database and a backup of each individual MicroSmart controller database. In addition, on an installation with ethernet NIMs, its configuration data is backed up as a separate step.   All three backup steps are done with OPRIF. Note:  Echelon NIMs do NOT require backing up.

Issue Cannot find third party bacnet IP devices Environment BACnet Third party device Find bacnet devices Cause Default router address was incorrectly configured in the third party device. Resolution Corrected the default router address configuration in the third party device.

Issue When the ENC is set up to pull weather data from the Enterprise Server the ENC's Application Director starts spewing out provisioning errors. Environment I/A Series G3 Cause When set up to do this the ENC uses provisioningNiagara functionality and requires that module be present in the ENC Resolution Install the provisioningNiagara module in the ENC.

Issue Need to know the connector genders to order the interconnecting ribbon cable. Environment DO-20 DM-20 DIO-20 Cause Not in the documentation for the DO-20. Resolution All three have a female DB25 connector. Also, the interconnecting cable from the DM-20 to the DO-20 or DIO-20 is a straight-through 25 conductor cable.

Issue Is Marathon's EverRun software directly supported by Schneider Electric? Product Line Andover Continuum Environment Continuum Marathon EverRun Disaster Recovery Software Cause Although supported for its use with Continuum as a DR solution, Schneider Electric does not provide direct support for EverRun. Resolution For support with this software, or more information on what they provide, contact Stratus Technologies (previously Marathon Technologies) directly (or one of their distributors in your location). Stratus Technologies support line can be contacted. A local point of contact for the EverRun software in Australia is the local distributor, Providence Solutions.

Issue When viewing Function Block Programs via the graphics viewer some values are not displayed correctly Environment SmartStruxure 1.3.0.938 and below Cause This is a known issue in 1.3.0.938 and below.   Resolution This is a known issue in 1.3.0.938 and below.  Upgrading to 1.3.0.10100 (1.3 SP1) or higher resolves this issue.

Issue Cannot import an XBuilder project properly into an existing project. Error states: "Template cannot be found" Saving and closing an XBuilder file of the project to be imported, all checks out fine with no errors.  Importing the project into the receiving controller results in "Template cannot be found error." Opening the project again results in the error "Failed to get file, it is recommended you exit XB without saving." Environment Windows Server 2008 R2 ( 64bit ) XBuilder Cause Xbuilder cannot see hidden files when it goes to search for the Device Template.  The default location is a hidden file under C:\Program Data\Schneider Electric\Device Library. Resolution Make your Program Data folder no longer hidden: Explore to the C: drive and in the upper left select Organize Select Folder and search options Click on the View tab Select the Show hidden files, folders, and drives radio button, then select OK

Issue V282 is obsolete and a replacement valve is requested.  Environment V282: 7218206000 7218210000 7218214000 7218218000 7218222000 7218226000 7218230000 7218234000 7218238000 7218242000 7218246000 7218250000   V241: 7214106000 7214110000 7214114000 7214118000 7214122000 7214126000 7214130000 7214134000 7214138000 7214142000 7214146000 7214150000 Cause Obsolete valve needs replacement. Resolution The recommended replacement valve for valve model V282 is V241. However, when so is done, pipe work will be necessary to adapt to installation with couplings and dimensions.

Issue Receive No Message Blocks Available when reloading or trying to access information on an Infinity controller. Environment Infinity controller Errors IO Bus I/O Modules Cause No Message Block errors indicate a very busy IO bus. Resolution The controller is out of message buffers in the CX.  The only way out of it usually is to reload the CX Check the DB to see if it’s correct offline Then hopefully a CX reset and reload fixes it. Might have to disconnect AC-1 if still an issue and commission 1 by 1 to get it back.

Issue When documents are edited from the system tree, on occasions any changes made can be lost. Environment Documents Changes not saved Changes lost Cause When documents are opened from system tree, and edited, after clicking save, and closing the word document, 20-30% of the time, SmartStruxure does not prompt to save the changes to SmartStruxure and the changes are lost.   Resolution This issue has been recorded in defect 21767, and is due to be addressed in release 1.4 SP1. There are two scenarios where this issue may occur; 1 - Changing windows and minimizing. Open document  from the system tree. Switch back to Workstation and minimize the window. Close the document currently being edited. In this situation, you are not prompted to save the document, and all changes are lost.   If the Workstation is minimized, SmartStruxure will not pick up the changes to the document. 2 - The second scenario relates to the "Save" prompts presented to the user. Open document and make changes. Close the document using the X You are presented with two prompts to save the document, the first is the original document name, and the second is the name given when added to the system tree. If "Yes" is not selected to both prompts, then any changes can be lost.
