Issue The setpoint values are displayed briefly and then change to 621.X on the Proview display? Environment All LON proview installations. Cause This occurs when the setpoints are being written into network variable inputs (nvi).  The nvi's default to using the receive heartbeat and will fallback to default after the timeout occurs.  Proview does not perform a send heartbeat function as the connection is an nv update and not an actual binding. The receive heartbeat mechanism in the MNL controllers cause the nvi values to fallback to NA upon heartbeat timeout. Resolution The heartbeat can be disabled for the setpoint nvi, however nvi values are stored in RAM (not EEPROM) and will return to default upon a controller power cycle.  The best solution is to use network configuration inputs (nci) for setpoint displays on the Proview.  These do not have the heartbeat issue and the values are maintained in EEPROM so they are not lost following a controller power cycle.

Issue Continuum analyzer reports errors in the IE Table Check. Environment Cyberstation Cause Errors need to be cleaned up using the Continuum analyzer. Resolution Clean up the errors using the Continuum analyzer then run the tests again to verify errors where corrected. If everything appears to work correctly then there is no need to reload the IE table to the controllers, otherwise: Send the IE table to CX level controllers. To send only the IE table select the 'Do not reload attached objects' in the 'Send To Controller Options' dialog window.

Issue The MNL-800 controller will not communicate with the WorkPlace Tech tool nor will it communicate with LON network management software tools such as LonMaker or the I/A Series (Niagara) R2/G3 LON Device Manager software. Symptom - Controller LEDs (top to bottom) Green Power and Transmit Data (Green) – on solid (normal power condition) Receive Data (Yellow) – may be flashing if data present on the bus Service (Red) – flashing a repeated abnormal pattern (long flash / short flash) Heartbeat (Green) – alternates on and off at a half second rate (normal) Environment MNL-800 on existing or new LON network WorkPlace Tech Tool software or LON Network Management software Cause An analysis of field returns has identified a condition where the MNL-800 fails to communicate and appears to be resetting continuously. The controller has entered a condition where the Neuron’s image has been deemed corrupted due to an application checksum error or signature inconsistency. When this occurs, the Neuron is unable to complete the startup sequence resulting in the MNL-800 continuously resetting. Resolution Follow the procedure documented in TPA-RKFD-09-0005.00 to reconfigure the communications processor in the MNL-800 controller. In the unlikely event that this procedure does not correct the communications issue, please contact Product Support Services for additional assistance.

Issue A power failure at the site causes all CyberStations to shut down, will the CX controllers buffer access events? what happens if the controller resets as a result of power glitch? Environment Cyberstation CX9702 CX9900, CX9940 CX9680 ACX5740, ACX5720 Cause -Power failure or controller reset due to electrical noise during thunder storm. Resolution 1. All controllers will buffer access events when they lose communication with the primary and secondary access server. 2. If the controller resets as a result of a power loss that exceeds the UPS capacity or due to a glitch or spike in the power line then whether the events will persists or not depends on the controller type. CX9702, CX9900 and CX9940 Access events in controller buffer will be lost CX9680, ACX5740 and ACX5720 Internal battery will keep RAM intact for up to 30 days Controller will warm start after a glitch or spike in the power line and maintain the events in its buffer. *** NOTE If controller has to cool start (restore its objects from flash memory) then the access events in the buffer WILL BE LOST. 

Issue When a SQL query is run on taclogdata to view events or trend logs, the time stamps returned differ by an hour or more from the those of the same events when viewed in Vista. Environment TAC Vista 4.3 and higher MS SQL Server Cause All time stamps are stored in taclogdata as UTC (Universal Coordinated Time) regardless of your local time zone and DST (Daylight Saving Time) settings. When you view events or trend logs in Vista, the Time Zone and DST settings of your Workstation are added to the UTC time so that you see time stamps synchronized with your local time. This does not occur when a SQL query is run directly on taclogdata. Resolution If you need to query the Vista SQL database directly, you could use the DATEADD function to calculate your local time from the UTC values, e.g. in SQL Server Management Studio run the following query to show the EventId, UTC time and local time for all events that occurred in the last 24 hours. USE taclogdata; SELECT EventId, EventDatetime, DATEADD(hour, datediff(hour, getutcdate(), getdate()), EventDatetime) AS LocalTime FROM Event WHERE EventDatetime > DATEADD(day, -1, GETUTCDATE()) Please note:  DATEADD adds a fixed offset to the input time.  It does not compensate for start and end dates of DST. 

Issue An end-customer purchased WorkPlace Tech 4.x several years ago and is retiring the computer.  The new computer will have the latest version of WorkPlace Tech.  Which part number applies to this upgrade from 4.x to 5.x?

When submitting the unlock code request, ensure that the original order number and/or PO number is included so that Customer Service can confirm that it is an upgrade, and invoice using the lower cost upgrade cost.

Issue A Cisco Mediator controller is connected via BACnet/IP to a Niagara R2 UNC.  The UNC station provides data to and receives commands from the controller.  The Cisco Mediator controller can read BACnet values but when it attempts to overwrite setpoints and issue commands, they do not work. Environment Niagara R2 all versions Cause The installation contains 3rd party BACnet controllers that must share data and commands. Resolution To allow other BACnet controllers to write values or issue commands to exposed Niagara objects, a special "BACnet" user is required for the station. To create this special user, follow the steps listed on pages 4-6 & 4-7 of Tridium's BACnet Integration Guide.

Issue Need to sequence several outputs to be on for 10 seconds then off for 15 then the next on for 10 and so on, but the site has specified no event sequences are to be used. Environment I/NET DDC Cause Need to sequence several outputs to be on for 10 seconds then off for 15 then the next on for 10 and so on, but the site has specified no event sequences are to be used. Resolution Create a DDC relay for output 1 that is an interval timer relay with the time set to 10 (time the device is on) Set the DI select to an input trigger point Create a second DDC relay to function as a delay before make relay. Set its time to 25 seconds, or the device on time plus the interval time before the next output. Set the output of this relay as a Line and the DI select as the trigger point. Copy the DDC relay from step 1. Change the DI select to the line from the previous step and the Output to the next device in the series. Copy the DDC relay from step 2. Change the DI select to the output triggered in the previous step and change the Output to a new line. Copy the DDC relay from step 1. Change the DI select to the line from the previous step and the Output to the next device in the series. Copy the DDC relay from step 2. Change the DI select to the output triggered in the previous step and change the Output to a new line. Repeat steps 5 and 6 until you have completed the series. If you wish for this to cycle in a loop, have the output from the last Relay trigger the DI point which starts the series. If this is an internal point you may want to add a calc to keep it equal to 0.

Resolution There are no supported applications or features to provide auto-logins to Continuum.  Continuum is a security system, and as such, it requires a login for auditing purposes.

Issue Procedure for obtaining a Return Authorization (RA) for a defective I/A Series (Niagara) G3 ENC Environment ENC-410, ENC-520 Cause Unknown - ENC is not functioning and needs to be repaired or replaced Resolution To request a Return Authorization for a defective ENC controller, the factory will need to know the following information: The product part number (ENC-???-?-?) Is the unit still under warranty? Warranty note: Warranty on a new UNC is 2 years from date of manufacture. The date code format is yyww. Example:  0815 is  2008 week 15 Serial number Job name (site name for unit) Factory order number Project ID Host ID (in the license file) The reason for return Network settings (IP, Subnet, name) Username and Password Station DB Username and Password Any special shipping instructions Have a purchase order number ready when you call. Note: Customer Support Services sends/bills for advance warranty replacement units. When the customer returns the correct unit within 30 days, a credit is then issued., Call Schneider-Electric at 888-444-1311 and select option 2 (Product Support). Product Support will enter a support case identifying the unit and that an attempt to troubleshoot was done prior to issuing the RA number. The caller should request the Product Support Case number and RA number for future reference. An RA will be issued based on the following criteria: Credit AWR (Advance Warranty Replacement). Customer is sending back an inoperable unit to the factory for credit and needs a replacement unit right away. OOWR&R (Out of Warranty Repair and Return). Customer sends back an inoperable unit to the factory for repair and return. IWR&R (In Warranty Repair and Return). Customer sends back an inoperable unit to the factory for repair and return. NOTE: When issuing an AWR, hold the defective unit and use the packaging from the replacement to return the UNC board. This will help guarantee that the units are not damaged during shipment. When the units are received damaged and improperly packed, they are returned as received and no credit issued.

Issue How to configure a Niagara G3 ENC serial port for dialup modem. Product Line TAC IA Series Environment ENC-520-2 ENC-410-1 Cause Dialup modem setup. Resolution In the Station, under Platform Services, go to the SerialPortService In the Port Config field, change the setting to Com1_232_com2_modem. Save this setting. Now, go to the Platform of the ENC, and go to Dialup Configuration The Init String should look something like this: ATE0S0=0Q0V1X4&D2&K3\N3%C2&C1&Q5W2 Change the 0 just after the "=" sign to a 2.  This will tell the modem to answer on the second ring. Make sure that the Port field says COM2 Check the Enabled box next to Listen for Calls In the Local IP Address field, type in the IP address of the ENC In the Remote IP Address field, type in an unused IP address on the same subnet as the ENC. Type in a User Name (eg. invensys) Type in a password (eg. niagara) Save your changes, then click the Start button at the bottom of the page.  This will start up the dialup daemon. Re-boot the station in Station Director.
