MC_GrpWriteParam

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

Inputs

Input	Data Type	Range	Unit	Default	Description
Execute	BOOL	0, 1	N/A	No default	On the rising edge A rising edge is the transition of a digital signal from low to high. It is also called positive edge, request to write a value to the specified Boolean group parameter.
AxesGroupRef	AXES_GROUP_REF	No range	N/A	No default	The axis group the Boolean parameter value is written to.
ParamNum	LREAL	See Axes Group Parameters.	LREAL	No default	Currently, one parameter is supported: MC_GRP_PARAM_CIRCLE_TOLERANCE: ID = 2000 The value read is the axes group circle construction tolerance. See Axes Group Parameters for more information.
ParamValue	LREAL	Parameter dependent.	Parameter dependent.	No default	The new value for the group parameter.

Outputs

Output	Data Type	Range	Unit	Description
Done	BOOL			If TRUE, the command completed successfully.
Busy	BOOL			If TRUE, the function block is executing.
Error	BOOL			If TRUE, an error has occurred.
ErrorID	INT			Indicates the error if Error output is TRUE. See the table in PLCopen Function Block ErrorIDs.
