Issue Official Product Announcement on the Discontinuation of Micronet 2000 and Network 8000 (PA_00152). Environment Micronet 2000 Network 8000 Cause Components for manufacturer no longer available. Resolution The following products will no longer be available after December 31, 2011:  

Issue How are two 4-20 mA loop-powered sensors wired into a MNL-200? Environment MNL controllers with at least two UI inputs (MNL-100, MNL-150, MNL-200, MNL-800) Cause n/a Resolution The image below provides a basic (but accurate) diagram of two loop-powered sensors and how they are wired with a power supply and a MNL controller.

Issue When trying to connect XPSI version 4.1 to a MicroZone II, using a B&B Electronics converter, model USOPTL4, an error is received: "No communications adapter found. Comm error = -5". Online XPSI functions may be grayed-out and not available: Environment XPSI version 4.1 USB / RS-485 adapter, B&B Electronics model USOPTL4 Network 8000 MicroZone II controller Cause One cause of the error appears to be closing the XPSI Site Group window: Resolution Leave the Site Group window open. Edit the Site setup. In the following example, the site is named "B&B converter to MZ2". To communicate to a stand-alone MicroZone II, the Network Number and GCM Number do not matter, they can be left at their default values. The "Connection Type" should be set to PSI HOST   The "Port" should be set to match the hardware port assigned to the B&B converter when installing its drivers. It will be named " RS-485 Isolated Port (COMx)". COM3 in the following example. Note the Universal Serial Bus Controllers, Model USOPTL4. Once the site is configured, access the controller: Enter the user name and password for the MicroZone II on the MicroZone II PSI Main Window:   In the "Functions" menu, use the arrow keys to move the cursor to "Device Number", and press "Enter". Type in the address of the controller, which is set by its DIP switch. The MZ2 is set to address = 1 in the example: While XPSI is connecting to the MZ2, the TD and RD LEDs on the model USOPTL4 should blink.  The  yellow (RX) and green (TX) LEDs on the MicroZone II should also blink. When XPSI is connected to the controller, the Main Window will display the device number. In the example, MZ II # 001 is connected: When finished accessing the MicroZone II, logoff and select "Disconnect" from the Access menu. This will properly shut down XPSI and the drivers for the B&B converter.

Issue I/A Series (Niagara) R2 station, needs a LON shadow object for a Square D Altivar 21 with Program ID 80:00:13:3C:0A:0A:04:50.  The closest match is Atv21, with Program ID 80:00:13:3C:0A:0A:30. Environment I/A Series (Niagara) R2 station in a UNC with a LON trunk, build 532, 529, or 522 Square D drive, Altivar 212, with LON card, Program ID 80:00:13:3C:0A:0A:04:50. Cause Square D Altivar 212 with a new LON profile and XIF file, program ID 80:00:13:3C:0A:0A:04:50 Resolution Download a new jar file: lonSquareD-2.303.532a.zip, which includes a shadow object named Atv212, manufacturer Id = TA_Control, and Program ID  = 80:00:13:3C:0A:0A:04:50. LonUtilities Manager after the jar file has been installed:

Issue How do I expose the temperature setpoint SNVT, nciSetPts, in a GxPage for Niagara R2? Environment Niagara R2 all versions Cause N/A Resolution The nciSetpt temperature values can be displayed and changed via graphic with the use of the SnvtTempSetptCmd conversion object. The SnvtTempSetptCmd object is located in the local library: /tridiumx/lonworks/conversion folder. The vt7600R shadow object was used in this example. Use the shadow object which matches the program ID of the device being used. Open the Local library and go to the /tridiumx/lonworks/conversion folder Copy and paste the snvtTempSetptCmd object to your Workspace. Link the nciSetPts property of the shadow object to the snvtTempSetpt property of the SnvtTempSetptCmd object and click ok. (see Figure 1) Figure 1. Add two GxText objects for each setpoint you want accessed and label them accordingly. (see Figure 2) Select the temp setpoint property under SnvtTempSetptCmd object and binding for the GxText property. (see Figure 2) Figure 2. Repeat step 5 for each setpoint to be exposed. Return to the Workspace view once all the desired setpoints have been exposed. You can now Right-click on the desired setpoint and change its value. Figure 3. Figure 4.

Issue In an R2 (Niagara) station with BACnet, getting errors in Standard Output Window, "Transport lockup detected!" and multiple "TException E_QUEUE_FULL {BClient}". Environment I/A Series R2 (Niagara) UNC station with BACnet service. Cause Queue sizes in BACnet Service are too small. See the BACnet Integration Reference, Chapter 6, "Configuring BACnetService Properties", "Engineering", Figure 6.4, and section titled "Message Queue Properties" for further details. Resolution Increase all three of the queue sizes(transportQueue, serverQueueSize, clientQueueSize) , from the default values of 16, up to 90.   Monitor the Standard Output Window for errors, and increase the queue sizes in increments of 50, up to 500. It may be necessary to reboot the station in order for the changes to take effect, because the changes are being made to a service.

Issue A Niagara R2 UNC has been installed in place of a DMS-3500 and two Microsmart trunks has been merged into one.  The trunks have been checked out physically and all controllers are powered, online, and ready to communicate to the UNC. A Device Discovery displays only a partial list of the installed controllers.  Why are the rest of the Microsmart controllers not being found? Environment Niagara R2 (all versions) Microsmart controllers (all versions) Cause A DMS-3500 has been removed and replaced with a UNC with the Microsmart driver.  The two Microsmart controller trunks have been merged into one trunk. Resolution In the Properties of the ibsMs service, ensure that the firstControllerAddress is set to 1 and that the maxControllers number is set to the same value of the licensedControllerCount. In the image below, the ibsMs service is licensed to communicate to 124 controllers but the maxControllers is only set for 60.  A Device Discovery from the ControllerListManager will only look for controllers addressed from 1 to 60.  Any controller addressed 61 and higher will not be searched for and, as a result, not discovered.  

Issue OPRIF 11.6 runs in a Command Prompt window and does not maximize to a full-screen.  This is observed on a Windows 7 computer. Environment OPRIF 11.6 Windows 7 (any version) Cause By design Resolution The Command Prompt window does not work in full-screen mode in Windows 7 as designed by Microsoft. OPRIF 11.6 was designed to work within a command prompt window.  As a result, it cannot operate in full-screen mode. By accessing the Properties of the command prompt window, it can be enlarged slightly: The Magnifier program which comes with Windows 7 can also be used to enlarge the command prompt window running OPRIF 11.6.  Screen resolution will be somewhat compromised.

Issue If there is an online selection tool for all the HVAC sensors (room temperature sensors, duct pressure sensors, etc.) Environment All Schneider Electric Buildings product lines Cause Since Schneider Electric manufactures a huge amount of sensors for different product lines. Sometimes it takes a bit of time to search for the right sensor. Therefore, Schneider Electric developed an online selection tool to help customer pick the right sensors. Resolution Click here to go direct to the online HVAC sensors selection tool. Select the desired features of the sensor. All sensors match the requirements will be displayed on the right. Datasheets can be accessed by clicking on the image or the part number. NOTE: the listed sensors may not be available in some region. Please contact the local sales or Support team to confirm the information.

Issue DuraDrive actuator feedback is 0-10 VDC or 2-10 VDC, controllers accept 0-5 VDC. Environment DuraDrive actuator (MS4x / MS5x series) MNL / MNB controllers Cause The voltage feedback output was designed for controlling slave actuators configured for 0-10 VDC or 2-10 VDC control signals. Resolution Use two 10k resistors as a voltage divider across the feedback leads with the center point connected to the controller input and the actuator common connected to the controller common. NOTE: Not all actuators in this product family use the wire colors shown for the feedback output. Please refer to the actuator GI sheet for the correct colors.    MNL / MNB Controller Analog Input Configuration For actuators with a 0 VDC to 10 VDC feedback output: Type= Volts Linput = 0 Lscale = 0 Hinput = 5 Hscale = 100 This input configuration provides a 0 - 100% output corresponding to the Actuator Position, based on feedback voltage 0 VDC = 0% and 10 VDC = 100% of actuator travel.  For actuators with a 2 VDC to 10 VDC feedback output: Type= Volts Linput = 1 Lscale = 0 Hinput = 5 Hscale = 100 This input configuration provides a 0 - 100% output corresponding to the Actuator Position, based on feedback voltage 2 VDC = 0% and 10 VDC = 100% of actuator travel.

Issue I/A Series R2 LON Device Manager does not allow me to perform a "Replace Node" to replace an MNL standard controller with a newer version of the same controller.  For example, replacing MNL-20RS1 with MNL-20RS3. MNL-xxRF2 replaced by MNL-xxRF3 MNL-xxRH2 replaced by MNL-xxRH3 MNL-xxRR2 replaced by MNL-xxRR3 MNL-xxRS1 replaced by MNL-xxRS3 MNL-xxRS2 replaced by MNL-xxRS4 MNL-xxRV2 replaced by MNL-xxRV3 Environment I/A Series R2, UNC-410, UNC-520 Cause Slight changes to the profile were made requiring a change in the device's program ID. The replace node will only succeed if the device program IDs exactly match. Resolution There are three methods to exchange the MNL shadow objects (e.g. MNLRS1 to MNLRS3, etc.).  The first method is to manually use WorkPlace Pro to delete the existing shadow, adding the new shadow object, and re-linking the associated logic. The second method is to manually edit an updated XML backup of the station database.  The following summarizes the changes required to convert a shadow object from V3.x controller profile to V4.x controller profile via XML. It is recommended to use an editor such as Textpad which is available at no cost and can be downloaded at http://www.textpad.com. Fan Coil Profile MNLRF2 replaced with MNLRF3 Heat Pump Profile MNLRH2 replaced with MNLRH3 Rooftop Profile MNLRR2 replaced with MNLRR3 Satellite Profile MNLRS1 replaced with MNLRS3 Satellite Profile MNLRS2 replaced with MNLRS4 VAV Profile MNLRV2 replaced with MNLRV3 The same modifications were made between the various profiles so the following can be used to modify each. Step 1: Replace the shadow object referenced in the text file with the appropriate new object. Do not modify the node name. For this example, replace MNLRS1 with MNLRS3.     Step 2: The nvoSecAlarm has been replaced by nvoDeviceAlarm. The only change was to remove the Sec (Siebe Environmental Controls) reference and make the nvo more generic in name. All other information (i.e. SNVT type, etc.) remains completely unchanged. Since the nvo was specifically designed to work with these devices, a binding will most likely not exist.  Note: There are two tags to edit, one tag at the start of the definition and one tag that ends the definition. Step 2: The nciSecModelNum has been replaced by nvoDeviceInfo. The network configuration property was removed to free precious EEPROM required to compile the new Echelon library. The SNVT type and index position remains unchanged. This nci was a manufacturer defined property and typically only read by the user. The information now is calculated and provided as an nvo. Replace the entire section. The third method is to use a utility included with the Smartware Tech WorkPlace Pro Utilities package.  A utility named “Profile Update” can be used to work on an offline XML to upgrade these objects. Additional information as well as Smartware's contact information can be found at http://www.smartwaretech.com.

Issue Error when attempting to use LON Tunneling, "Service unavailable, Another application already connected in remote station". This message indicates that another user is already connected to the device through Lon Tunneling. Environment I/A Series (Niagara version 522 or higher) R2 UNC with LON Tunneling Lon Tunnel client Cause The general cause is that the computer disconnected the LON connection before closing the LON Tunnel. There are a number of different reasons this can happen when you have the LON tunnel connection open: Laptop goes into sleep mode while tunnel is connected. Disconnecting laptop from Ethernet network before closing WorkPlace Tech Losing the network connection Shutting down the laptop without exiting from WorkPlace Tech. Resolution This problem can be corrected without having to reboot the UNC by accessing the UNC Webserver Status Summary screen and clicking disconnect on the VLON connection.  The procedure is as follows: Access the UNC using your web browser and the following command: http://<ipaddress>/prism/webserver     A screen similar to the following will be displayed:   In the "All Threads" section, locate the line that shows the Uri "/vloncomm0/Vlon" and click the "Disconnect" link button.  This will cause the Vlon connection to be forcibly closed.  Once the connection has been closed, the LON Tunnel connection will again become available for a client connection.

Issue Niagara R2 is installed on a computer but the HostId is not known.  Aside from viewing the details of the license.properties file, how can the HostId be determined? Environment Niagara R2 Cause No access to the license.properties file Resolution Open the Niagara Console (located in the Program Group), and type the following: nre -hostid This will display the HostId to the screen (see the screenshot below) The  nre command can also display other information.  The screenshot below shows the other options.

Issue There are six object types when adding to a Network 8000 network in the Equipment Database.  When should each type be selected? Environment TreeTech 3.x Network 8000 GCM and LNC Cause Each type provides the necessary support for the different block types available in the different Network 8000 GCMs and LNC.  An upload will fail if block support is not available because the wrong object was chosen. Resolution Select the correct object type to match the field-installed Network 8000 panel. ASDGCM4  - A GCM-84000 series using revision 4.x firmware and configured with an ASD bus ASDGCM5 - A GCM-84000 or GCM-86000 series using 5.x firmware and configured with an ASD bus GCM4 - A GCM-84000 series using 4.x firmware and configured with GCS modules GCM5 - A GCM-84000 series using 5.x firmware and configured with GCS modules GIM 2100 - A Global Integration Module for System 2100 SIM GCM - same as a LNC-100

Network 8000 LCM, on LCM bus under a GCM Network 8000 GCM with LCM bus Cause Although the pull-down menu for the Gcm Device Manager has  entries for "New" LCM and stand-alone LCM, selecting them results in the error. Resolution Add the LcmDevice manually: Open the tacGcm palette. Expand the Devices folder and copy an LcmDevice. Paste the LcmDevice into an existing GcmDevice. Configure the LcmDevice object to match the physical LCM controller  by setting the Panel and Network Number. In the example shown below, the Panel = 11 (as set by the DIP switch on LCM), and Network Number =1.

Issue Is there a way through Niagara G3 WorkBench to log into multiple ENC/ENS stations without being re-prompted for the Username and Password for each station?  Environment Niagara G3 (version 3.3 or higher), ENC, ENS Cause Is there a way through Niagara G3 WorkBench to log into multiple ENS/ENS stations without being re-prompted for the Username and Password for each station? Resolution Starting in AX-3.3, a multi-station “realms” feature was added. This feature allows a Workbench user to open one station (fox), then have Workbench access to other stations, without re-prompting for credentials. The following must be performed in each station, where each station must have the same “realm” name: Open the property sheet of the root-level Config component in the station. In the “Sys Info” property, click the Facets control (>>) for the Config Facets editor. The Config Facets editor appears  Add a key named “realms” of type String, with the string value (whatever desired) for the realm name. To do this in the Config Facets dialog: Click the “+” button. Under Key, select “realms” from the dropdown menu. Under Type, be sure that String is selected. Click in the “Value” field and type the name of the realm. Note this realm value has no literal meaning, but must be the same for all stations. Click OK to add the facet. See figure below for an example of realm "shazam" being added Repeat this procedure for every station that’s part of the single sign-on realm. Note: This feature requires that the user has an account (with same credentials) on each station in the realm.  Otherwise, the user will still be prompted to login. For additional information, reference the section, “WorkBench single sign-on (SSO) realm”, located in chapter 9 of the Niagara AX-3.x User Guide.
