string to write

Defines the data string to write to the output port or system log.

datatype_icon

interface

Defines whether to send the string to an output port or to write the string to the system log.

Name Value Description
Write to monitor 0 Sends the debug string to the video port. If no video port is available, this option sends the debug string to the console.
Write to system log 1 Sends the debug string to the nierrlog system log located in /var/local/natinst/log/errlog.txt on the target.

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

error out

Error information.

The node produces this output according to standard error behavior.
