Function Block A function block groups an algorithm and a set of private data. It has inputs and outputs. - Writes the specified axis parameter.

Inputs

Input	Data Type	Range	Unit	Default	Description
Execute	BOOL	FALSE, TRUE	N/A	No default	Requests to write an axis parameter.
Axis	AXIS_REF	1, 256	N/A	No default	Name of a declared instance of the AXIS_REF library function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances.. See Axis Name and Number. See AXIS_REF Structure.
ParameterNumber	INT	No range	N/A	No default	Parameter number. See Axis Parameters.
Value	LREAL	No range	N/A	No default	Value to write.

Outputs

Output	Data Type	Range	Unit	Description
Done	BOOL	FALSE, TRUE	N/A	Indicates the parameter has been written.
Busy	BOOL	FALSE, TRUE	N/A	Indicates this function block is executing.
Error	BOOL	FALSE, TRUE	N/A	Indicates an invalid input was specified.
ErrorID	INT	-32768 to +32767		Indicates the error if the Error output is set to TRUE. See PLCopen Function Block ErrorIDs.

Remarks

This function or function block returns cached data.
See Program a Multi-Core Controller.
