Getting Started

To get started with the NodeBuilder software, follow these steps:

1.      Install a 32-bit version of Microsoft Visio.  Microsoft Visio is required for the IzoT Commissioning Tool (CT).  You cannot install 32-bit Visio on a computer with 64-bit Microsoft Office.  If you have 64-bit Office, uninstall it before installing Visio.

2.      Install IzoT CT.  IzoT CT is required for the NodeBuilder software.

3.      Download the NodeBuilder software from

4.      Extract the files from the NodeBuilder zip archive.

5.      Run the NodeBuilder.exe application to start the NodeBuilder software installation.  You can install the NodeBuilder software on the same computer with an earlier version of the NodeBuilder software.  The new NodeBuilder software will delete any prior installations.

6.      When you are prompted for a serial number, enter the following serial number:


7.      See the IzoT Commissioning Tool User’s Guide and the IzoT NodeBuilder User’s Guide for details on using IzoT CT and NodeBuilder.  These manuals are installed on your computer when you install the IzoT CT and NodeBuilder software. You can find the documents online on the following pages:

8.      If you are using the IzoT WireShark Plug-in, update your WireShark software to version 1.12 or newer.  The version of the IzoT WireShark plug-in included with SR2 and newer will not work with versions of WireShark prior to 1.12.

9.      If you created any custom devices with Neuron firmware 21.03.07 included with the original NodeBuilder 4.3 software, or with Neuron firmware 21.03.09 included with the NodeBuilder 4.30 SR1 software, or if you have an FT 6000 EVBs shipped prior to October 2014 that are running Neuron firmware version 21.03.09 or earlier versions, then update the firmware in your devices or EVBs to match the new Neuron firmware 21.04.08 firmware included with the service release.  To update the firmware in your devices or EVBs, follow these steps:

1.      If you do not already have a current version of NodeLoad or NodeUtil, download and install one of the utilities from  If you are downloading NodeUtil, also download the latest NodeUtil Node Utility User’s Guide.  NodeLoad is easier to use for just downloading images to device, whereas NodeUtil provides other useful tools for device developers, including tools for verifying Neuron firmware version numbers.

2.      Download the following boot loader file with NodeLoad or NodeUtil:


Enter your LonWorks directory for <LonWorks>.  By default, the LonWorks directory is C:\Program Files (x86)\LonWorks or C:\LonWorks depending on which Echelon software you previously installed on your computer.

To download with NodeLoad, enter NodeLoad /? to display help.  To download with NodeUtil, see the NodeUtil documentation for the Y command.

3.      Download the following Neuron firmware image file with NodeLoad or NodeUtil:


4.      If you are using NodeUtil, you can verify the firmware version number with the S command.

5.      Rebuild any applications you created for your custom devices or FT 6000 EVBs using Neuron firmware version 21.04.08.


The following fixes are included in IzoT NodeBuilder 4.4 Update 1

The following fixes are included in IzoT NodeBuilder 4.4

The following fixes are included in IzoT NodeBuilder 4.3 SR8.

The following fixes are included in IzoT NodeBuilder 4.3 SR7.

LodInitSettings lis = {0x80, 0x0F00, 0x07};

Then the backward compatible code would be:

LodInitSettings lis = {0x80, 0x0F};

Yes, this allocates more sectors (0x0F) than originally intended (0x07), but it will do so in a way that matches what actually occurred in the old device.  [NDB-5674]

The following enhancements are included in IzoT NodeBuilder 4.3 SR6.

This error has been corrected; IzoT NodeBuilder Hardware Template Editor reads “neuron.xml” data correctly, regardless of local and regional settings. [NDB‑5661]

This error has been corrected and the network kernel debugger’s message buffer is correctly accounted for. [NDB-5662]

The following enhancements are included in IzoT NodeBuilder 4.3 SR5.

The following enhancements are included in IzoT NodeBuilder 4.3 SR4.

The following problems were fixed in IzoT NodeBuilder 4.3 SR3.

The following problems were fixed in IzoT NodeBuilder 4.3 SR2.

The following problems were fixed in IzoT NodeBuilder 4.3 SR1:

·         Power failure recovery has been improved when downloading an NDL file.  (NDB‑5409)

·         Network variables bound using the alias table (such as can occur with fan out connections) were not always updated properly.  (NRNFW-509)

·         Memory was sometimes corrupted when loading large applications.  (NRNFW-500)

·         Memory allocated for sending a message was sometimes not freed if application_restart() was called while sending a message.  (NRNFW-498)

·         If an application contained eeprom far data and all of it was declared as uninitialized (uninit without any explicit initializers), the exporter sometimes crashed when creating the NEI or NDL files.  Variables declared with the uninit eeprom far attributes variables and not explicitly initialized are now initialized to zero in the NMF file.  (NDB-5466)

·         The NME file generated by the NodeBuilder software for programming serial EEPROM memory parts for a Series 5000 Smart Transceiver or Neuron Chip was sometimes corrupted, preventing the device from operating correctly.  (NDB-5462)

·         Open Media Authentication (OMA) could be enabled for targets with version of Neuron firmware prior to version 14 that do not support OMA.  (NDB-5462)

·         Linker errors were reported by the retrieve_stat() function for the _stats_unlock and _stats_lock symbols.  (NDB-5460)

·         An incorrect offset out-of-range error was sometimes reported when compiling an application.  (NDB-5423)


Following are warnings for NodeBuilder.

Testing an IzoT Router from IzoT CT Fails

If you use the Test command from the IzoT CT Manage window to test an IzoT Router, you may see the following error message: "OpenLNS CT was able to communicate with the device using Neuron ID addressing, but could not communicate with the device using subnet/node addressing.  However, through the use of Neuron ID addressed messages, OpenLNS CT has verified that the device contains the expected subnet/node address."  Workaround: Add the IzoT Router to your network as described in the Setting Up the IzoT Router and Installing the IzoT Router in a Network topics in the IzoT Manual at  (IZTR-82)

FT 5000 Examples do not Compile

The NcMultiSensorExample, NcSimpleIsiExample, and NcSimpleExample examples for the FT 5000 Smart Transceiver fail to compile—the examples for the FT 6000 Smart Transceivers compile correctly.  Workaround: No workaround is required if you are building the FT 6000 examples for an FT 6000 Smart Transceiver.  To rebuild the FT 5000 examples for an FT 5000 Smart Transceiver, replace all include directive double backslashes with single backslashes.  (NDB-5384)

Changes in Default ISI Domain

The LonTalk/IP default domain for ISI is 0x49.53.00 ("IS\0").  This is a change from the original ISI default domain of 0x49.53.49 ("ISI").  Workaround: To use the LonTalk/IP default ISI domain, no workaround is required.  To create ISI devices operating on the original ISI default domain of 0x49.53.49 (“ISI”), assign the 0x49.53.49 primary domain ID by overriding the IsiGetPrimaryDid() callback function.

If DHCP is enabled and an IP address is assigned by a DHCP server, the Neuron firmware will use the IP address assigned by the DHCP server, and will not use the default ISI domain.  Workaround: To use the default ISI domain, use the #pragma dhcp disabled directive to disable the DHCP client for your devices when using ISI.  (NDB‑5337)

IzoT CT Browser Fails after Installation

The IzoT CT Browser sometimes displays a system error when started after installation.  Workaround: Restart Windows to complete the installation.  (LMWIN-1930)

FT Termination

An FT terminator is required for the FT 6000 EVK network.  The IzoT Router includes a built in terminator for the FT network that is enabled by default.  Workaround: Do not use a standalone FT network terminator if you enable the IzoT Router built-in terminator.  (IZTR-77)

Locating the Neuron C Example Project Sources

After restoring the IzoT NcMultiSensor example network, you must specify the NodeBuilder project.  When prompted whether to create a new or open an existing project, select Open an Existing Project and browse to the NcExamples.NbPrj project located in your local C:\Users\Public\Documents\LonWorks\OpenLnsCt\Source\FT 6000 EVB folder.  (NDB-5374)

SCI Rates Missing for BACnet FT Device

When building a device with BACnet FT support, the examples include a file blonsys.h.  blonsys.h references a variable of type TSciRates, which is defined in io_types.h, so within your own project, before including blonsys.h, also include io_types.h (NDB‑5668).

The __slow and __fast Keywords Scale with System Clock

The “IO Model Reference for Smart Transceivers and Neuron Chips” implies that using the __slow keyword gets you an SCL rate of 100 kbps, and the __fast keyword gets you a 400 kbps rate.  While this is true with a system clock of 80 MHz, note that the SCL clock rate scales with the system clock rate (NDB-5663).

The 100k Pull-down on MISO for Flash is Required

The “6000 Series Chip Data Book” claims that for the flash memory interface, the 100k pull-down on MISO can be omitted.  Instead, this pull-down is required (NDB‑5656).

Install failure with Visio 64-bit

IzoT CT requires the 32-bit version of Microsoft Visio. Existing installations of the 64-bit version of Microsoft Visio can cause Izot NodeBuilder not to install correctly. Running IzoT NodeBuilder causes runtime errors in reference to missing dynamic link libraries (DLL).

Uninstall Microsoft Visio and re-install it from the Open CT installation media provided. Then execute the "repair" option with the IzoT NodeBuilder installer from the Windows Control Panel. [NDB-5750]
