variable index). The data from the last network variable update to the selected

network variable is displayed.

At the prompt, enter the data to be sent to the network variable, in hexadecimal

bytes. Separate each pair of hexadecimal digits with a space, and enter all the

required data on one line. The data values for any bytes that you do not enter
after the first character default to zero. For example, you can enter 01 00 00 or
just enter 1 to set a SNVT_switch_2 input network variable to the on state.
Press ENTER without any characters to cancel the update so that the input

value is not changed.
You can use the Set the (D)omain of the network interface command to configure
the NodeUtil network interface with a domain and authentication key to match

those of the destination device if the network variable has been configured as

authenticated.

V – Control Verbose Modes

Use this command to enable or disable two verbose modes: for network interface

messages and for network traffic. These modes are useful for debugging network

problems. By default, network interface message verbose mode is off, and
network traffic verbose mode is on.
If you enable verbose mode for network interface messages, NodeUtil displays the
contents of all application buffers going to and coming from the NodeUtil network

interface.
If you enable verbose mode for network traffic, any incoming message addressed
to the application processor on the network interface is displayed.

W – Write Device Memory

Use this command to write to the memory of the selected device. You can specify

the starting address in hexadecimal format. The contents of the memory address
that you specify are displayed in hexadecimal. Enter a new value for the location

in hex and then press the ENTER key, or press the ENTER key with no data to

leave the value unchanged. To stop entering data, enter any value that is not a
hexadecimal character, such as a period (.), and press ENTER.
If you change any of the data in memory, you are given the opportunity to update

both the application and configuration checksums, or just the configuration
checksum.
Important: The device should be in the applicationless state before you change
any of the application image memory, otherwise the device will report an

application checksum error. Similarly, the device should be in the applicationless

or unconfigured state before you change any of the network image memory,
otherwise the device will report a configuration checksum error.

X – Create Device Interface (XIF) File

Use this command to create a version 3 device interface file (.xif extension) for

the selected device. You can enter a file name for the XIF file. If the device has
an alphanumeric program ID, this ID is the default filename. You can use the
