MOVE

Type Function

Description Assigns the variable connected to IN to the variable connected to OUT.

Note When the string output is longer than 80 characters and the FU/FB is directly connected to another FU/FB, temporary string variables of size 80 are used. Calculation/usage will fail. Use an intermediate local variable in-between.

Parameters Input
IN

Data type: ANY

Description: Input value.

Output
OUT

Data type: ANY

Description: Output value.

Error behavior Error behavior

The following table shows the errors which may occur while executing the function and the value returned by the function in the corresponding error case.

Error case Output value

IN = NaN
Note: ENO stays true in the error case. NaN

IN = Inf+
Note: ENO stays true in the error case. Inf+

IN = Inf-
Note: ENO stays true in the error case. Inf-

Resulted string too short Empty string

Note
String comparison: In case of a string error, the function returns the empty string ''. Furthermore, the controller runtime logs the error in its error catalog and a corresponding error message is shown in the Error List.

Note
Controller stop on string error: The controller can be automatically stopped when a string error occurs. This allows you to locate the error in your project. To enable the automatic stop of the controller in case of a string error, activate the button in the Cockpit toolbar of the controller.

Additional information EN/ENO behavior

The POU is only executed if TRUE is applied to the EN input. If EN = FALSE, the POU is not executed and ENO = FALSE indicates the inactivity.

There is no error case (see "Error behavior" above) which sets ENO to FALSE.

Invalid real values are passed to the output without setting ENO to FALSE because the function does not interpret values.
