MCV_SaveParamChg

Save modified parameters

After successful activation of a work list, this function block saves it as the original list. The previous work list is deleted after successful storage.

Thus, after a restart of the controller or after a parameter set change, the modified parameters are permanently available in the original list.

CAUTION
If a warning has occurred on activation of the work list, at least one parameter has been corrected in the controller. This corrected value is not included in the original list. When the original list is read in, the warning appears again and the parameter value is corrected again.

Parameters of the FB

VAR_IN_OUT
	Axis	AXIS_REF	Axis reference
VAR_INPUT
	Execute	BOOL	Saving of changed parameters at rising edge.
	NCListTypeIn	STRING	Identification of parameter or list type, e.g. ACHS_MDS.
	NCParamSetIDIn	UINT	Number of parameter set to be saved.
VAR_OUTPUT
	Valid	BOOL	Indicates if saving of the changed parameters has been successful.
	Busy	BOOL	Indicates if the function block is still busy.
	NCListTypeOut	STRING	Identification of parameter or list type, e.g. ACHS_MDS.
	NCParamSetIDOut	UINT	Number of the parameter set which had to be saved or has been saved.
	NCWarning	BOOL	Indicates if a warning in the ISG-MCP has occurred.
	NCError	BOOL	Indicates if an error in the ISG-MCP has occurred.
	NCErrorCode	UDINT	Error identification of the error in the ISG-MCP.
	Error	BOOL	Indicates if an error has occurred. Save of parameter set is not executed.
	ErrorID	WORD	Error identification.

Behavior of the FB

The FB is in an error state if Error = TRUE. The parameter set has not been saved correctly. An error has occurred either in the function block itself or in the ISG-MCP. The NCError output parameter indicates whether an error has occurred in the ISG-MCP.
A frequent cause of ISG-MCP errors are absent write privileges or a write-protected original list because, in these cases, the original list cannot be replaced.
