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
