Issue How should the Micro Energy Power Supply voltage reading be checked? Can the Micro Energy Power Supply provide power to IOU only without CIU connected? Environment Infinity SX8000 Cause Got the Micro Energy Power Supply repaired by 3rd party but the voltage reading seems to be incorrect. Resolution The voltage of the Micro Energy Power Supply should be checked with the load connected to the PS.   For the port_A voltage check, have the CIU connected to the port_A of the PS.   For the port_B voltage check, have the IOU connected to the port_B of the PS. Also the Micro Energy Power Supply can have either the port_A connected to CIU only or the port_B connected to IOU only or both ports connected to CIU and IOU respectively. For detail information of the voltage reading of each pin, please refer to page 2-86 ~ 2-88 of the AC256 Service Manual.pdf

Issue Objects appear to be edit locked, however no asterisk appears in the editor title bar. Environment Cyberstation Continuum Users Cause Continuum user permissions had been restricted. Resolution Restored full edit permissions to Continuum User.

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.
