Issue SNVT_press_p cannot represent a value above 32766 Pa Sending a value of 15psi out of a Menta application using a SNVT_press_p and it is arriving at the receiving controller as 4.75psi. Environment SNVT_press_p Menta LonMaker/NL220 Cause All LON communication is transmitted in metric units, so the data sizes are limited by the valid range of Pascals (or kiloPascals for SNVT_press). Resolution There are three different SNVT types defined to represent a pressure (gauge) value. SNVT_press, SNVT_press_f, and SNVT_press_p. It is important to recognize the valid ranges of data each one can represent. Name Units Maximum Minimum SNVT_press kiloPascals 3,276.70 -3,276.80 psi 475.25 -475.26 inches wc 13,154.74 -13,155.15 SNVT_press_f Pascals 3.40E+38 -3.40E+38 psi 4.94E+34 -4.94E+34 inches wc 1.37E+36 -1.37E+36 SNVT_press_p Pascals 32,766.00 -32,768.00 psi 4.75 -4.75 inches wc 131.48 -131.48

Issue What is the scan rate for the inputs and outputs of a MNL-20R? Environment MNL-20R Cause Require fast response time for high-speed applications. Resolution Inputs = 220 ms Outputs = 100 ms

Issue Using Workplace Tech with a MNL-VxRVx controller, the nciBalanceOvrd snvt was used to set the VAV damper to the full closed and full open positions. After 10-15 minutes the override was automatically cleared. Why does this happen? Environment Workplace Tech MNL-VxRVx controller Cause This is a built-in feature of the MNL-VxRVx controller. Resolution The override on this snvt times out and clears automatically - unless the override is re-applied every few minutes. This feature was added to prevent the damper from being left in an override state accidentally. For example, when using the MicroNet Flow Balance Tool, a damper can be overridden open or closed as a part of a test balance. If the Tool was accidentally disconnected from the controller, or, the user forgot to release the override, the MNL controller will clear the override automatically after 10-15 minutes.

Issue Can a Belimo damper actuator (i.e. NF-24SR) be powered from the same transformer as a DMS MSC-MPC Microsmart controller? Environment Belimo damper actuator DMS MSC-MPC (Microsmart controller) Cause The MSC-MPC controller is a full-wave rectified device and the Belimo actuators are half-wave rectified devices. Resolution It is recommended that the MSC-MPC and the actuator have their own separate power supply. Using the same transformer to power both devices could result in component level damage to the MSC-MPC.

Issue Remove a TAC Xenta OP that is commissioned in LNS from the LNS network. Product Line TAC Vista Environment TAC Xenta OP installed and commissioned in an LNS network Cause If an installed OP is to be removed from the LNS network, it should be restored to the original factory setting to avoid problems, before it is used in another LonWorks network. Resolution OP version >= 3.40 Check in the OP Service menu #10. OP mode that Mode is set to MAN, Disconnect the OP electrically from the LonWorks network. Remove the OP from the LNS database. OP version < 3.40 Check in the OP Service menu #10. OP mode that Mode is set to TAC or MAN, (in OP version < 3.11, Bindable OFF). Start the LonMaker Browser. Restore SNVT_config_src from cfg_external (1) to cfg_local (0). SNVT_config_src may be called var_2 in the Browser. Disconnect the OP electrically from the LonWorks network. Remove the OP from the LNS database. Factory setting If the OP has been de-installed in an incorrect way, it may be restored to the factory setting in one of two ways: Reconnect the OP to the network, reinstall it and perform the steps above in the correct order, Use the Nodeutil program and perform the following. Select OP Service menu #10. OP mode that Mode is set to TAC or MAN, (in OP version < 3.11, Bindable OFF). Start Nodeutil. Press the Service pin of the OP. Type G (Goto) Type 1, and then press Enter.

Issue On a Niagara R2 computer, the following error appears (in the Niagara Console) when trying to run Workplace Pro: *** Unjar: c:\niagara\r2.301.522\nre\modules\demo.unjar Extract: c:\niagara\r2.301.522\nre\modules\demo.unjar java.util.zip.ZipException. Environment Niagara R2 computer Cause .unjar files in the listed directory on the computer. Resolution The .unjar files are used by the Niagara installer during installation and have somehow been copied into the listed directory on the computer. Stop the Niagara Service on the computer, delete all .unjar files in the listed directory, then re-start the Niagara Service. Workplace Pro will now function.

Issue Can one computer be configured to do both Niagara R2 and G3 serial tunneling? Environment Computer Niagara R2 serial Niagara G3 serial Cause Running Niagara R2 and G3 simultaneously on one COM port cause issues. Resolution Yes. The Niagara R2 and G3 serial tunnel client programs install separate services in Windows. They can run simultaneously as long as they are not using the same COM port. If this is not possible, then start and use only one service at a time.

Issue How does a Niagara R2 Master Enterprise Server work? Environment Niagara R2 Master Enterprise Server Cause Installation site have Master Enterprise server and need information on the functionality of the Niagara R2 Master Enterprise Server. Resolution Here is a list of features and settings for a Master Enterprise Server: It allows the archiving of logs from subordinate Enterprise Servers It requires the “multisite” feature in its license file.  This allows it to use the “Poll Archive” Service. The Poll Archive Service can be found in the local library / tridiumx / Multisite jar file. The Poll Archive Service is not required for the client devices. The Poll Archive service brings all data from the Application Database (“App” Folder) of the subordinate Enterprise Server. The new polled data is appended to the previous polled data in the Master Enterprise Server. The Address Book of the Master Enterprise Server must include the client stations as subordinates. Poll Archive Groups are individually enabled and each group has its own poll frequency. On the properties of the Poll Archive Service, enable the appropriate Poll Archive Groups and enter the poll frequency, in hours. A Date-Time Trigger object can be linked to the Poll Archive Service, which allows a choice of date and time for polling. Use the “Link From, Link To” method to create the link. A poll can be manually invoked by right-clicking the Services Container, choosing Go – Service Manager and then double-clicking the Poll Archive Service in the Service Manager. On the right of the screen, highlight the Poll Group and click the “Invoke” button on the lower right. It can get log data directly from log objects in a UNC 5x0 or 6x0. In the log object, check the box for “polled” next to archiveSetup. If the Master Enterprise Server is receiving polled data from a log object in a client station (which could be another Enterprise Server, a UNC 6x0 or a UNC 5x0), then the log service for the client station must be set to Archive Remote. If the Master Enterprise Server is receiving polled data from a client station’s already archived data (that is, from another Enterprise Server or a UNC 6x0 with Database Services), then the log service for the client station must be set to Archive Local. The Address Book of the client device does NOT need to include the Master Enterprise Server. The Poll group will be determined by the Master Enterprise Server’s Address Book. The archived data in the Master Enterprise Server can be viewed, as usual, in WorkPlace Pro with the Database Browser, or in the browser using the appdb, archive/index or chart/log servlets.

Issue A Niagara R2 Enterprise Server station fails to start. The Standard Output Window reports this error: ERROR: Cannot add key entry: 8390 java.lang.IllegalStateException: Missing class for: 24 Environment Niagara R2 Enterprise Server station Cause Conflicting jar files. Resolution This is typically related to a missing jar file. This would be a jar file that is NOT part of a released version of Workplace Pro. For example, the Smartware and Distech jar files.

Issue Can a Network 8000 Microzone II base from 1993 (part numbers MZ2A-105 or MZ2A-106) be used with a MNL-800 controller card (part number MNL-800-101)? Environment Network 8000, Microzone II Cause Product  obsolescence Resolution The Microzone II base has been through a few revisions but nothing that would prevent the MNL-800 controller card from working with it.  Most of the revisions had to do with improving the power transient protection. If this is not a concern, then just note that the terminations and terminal labels will be slightly different.  Ensure all I/O is reading correctly before leaving the jobsite. ENCL-MZ800-PAN & ENCL-MZ800-WALL are replacement part numbers for the MZ2A-105 or MZ2A-106.

Issue Can a second space sensor be added to the Micronet 2000 MN-FLO or MN-FLO3T controller? Environment MicroNet 2000 MN-FLO / MN-FLO3T controller MN-S MN-SO MN-SDK Cause Two MicroNet Sensors to one MicroNet Controller won’t function if the second MicroNet sensors address is not set to 2. Resolution Yes. The MN-FLO and MN-FLO3T supports 2 MN-S / MN-SO / MN-SDK sensors connected simultaneously. Ensure the second sensor added is addressed as "2". The sensors come from the factory addressed as "1". To change the address, simply cut the Trace Foil. The sensor that is address 2 will only function as a temperature indicator. Review the MN-S/MN-SO/MN-SDK General Instructions Guide (F-25715), page 7 Figure 8.

Issue How does the nciSetpts snvt integrate to Niagara R2 for a Viconics Thermostat Model # VT7200C1018E (programID = 80:0:c5:55:0:4:4:1b) Environment Niagara R2 Viconics Thermostat (Model# VT7200C1018E) Cause Information will help configure the Niagara R2 for a Viconics Thermostat. Resolution The correct shadow object is T7XFCr. Use the SnvtTempSetptCmd object to link with the nciSetpts snvt. Note that if a setpoint is changed at the thermostat's local display, it will be used as the controlling setpoint regardless of the value provided by the nciSetpts snvt.

Issue In a Niagara R2 Enterprise Server station, the DDE Service is installed but it is not communicating to the 3rd-party product. Environment Niagara R2 Enterprise Server station DDE Service Cause No longer support the DDE service. Resolution The DDE driver is an old driver that Tridium did not update over the years. Its last supported operating system is Windows 2000. Product Support Services does not support this driver and Tridium does not recommend using it for any new installations.
