MOVE

Type	Function
Description	Moves the value of the operand connected to IN to the operand connected to OUT.
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. Further Info See the topic "General information on execution control with EN/ENO" for further details.
