Many LabVIEW nodes, such as VIs, contain error in parameters you can use to manage errors. These parameters typically provide the same, standard functionality. When a node exhibits different parameter functionality, the exceptions are documented in the reference material for that node.

Standard error in behavior is as follows:
Note Some nodes, such as error handling VIs, contain an error in parameter that does not provide standard error in functionality, but that contains an error in cluster that is standard.
The error in accepts error information wired from previously called VIs. Use this information to decide if any functionality must be bypassed in the event of errors from other VIs. Right-click the front panel error in control and select Explain Error or Explain Warning from the shortcut menu for more information about the error displayed.
status is TRUE (X) if an error occurred before this node ran or during the running of this node, or FALSE (checkmark) to indicate a warning or that no error occurred before this node ran or during the running of this node.
code is the error or warning code. The default value is 0. If status is TRUE, code is an error code. If status is FALSE, code is 0 or a warning code.
source specifies the origin of the error or warning and is, in most cases, the name of the node that produced the error or warning. The default is an empty string.
