message. Using error in and error out clusters is a convenient way to
check errors and to specify execution order by wiring the error output from
one subVI to the error input of the next.
status is TRUE if an error occurred before this VI was called, or
FALSE if not. If status is TRUE, code is a nonzero error code. If
status is FALSE, code can be 0 or a warning code.
code is the number identifying an error or warning. If status is
TRUE, code is a nonzero error code. If status is FALSE, code can
be 0 or a warning code. Use the error handler VIs to look up the
meaning of this code and to display the corresponding error
message.
source is a string that indicates the origin of the error, if any.
Usually, source is the name of the VI in which the error occurred.
error out is a cluster that describes the error status after this VI executes.
If an error occurred before this VI was called, error out is the same as
error in. Otherwise, error out shows the error, if any, that occurred in this
VI. Use the error handler VIs to look up the error code and to display the
corresponding error message. Using error in and error out clusters is a
