MC_ReadMotionFunction
The function block MC_ReadMotionFunction can be used to read the data of a motion function. Either the complete function with all interpolation points or only a part can be read. The data are stored within the PLC in the structure described by CamTable.
Inputs
VAR_INPUT
Execute : BOOL;
CamTableID : MC_CAM_ID;
PointID : MC_MotionFunctionPoint_ID;
NumPoints : UDINT; (* 0 = fill MFsize *)
END_VAR
Execute |
The command is executed with rising edge. |
CamTableID |
ID of the loaded table. |
PointID |
Point ID of the first point of the motion function to be read. |
NumPoints |
Number of motion function points to be read. For reading all points, 0 can be specified here, in which case the number that is actually read is returned in the output variable NumPointsRead. |
Outputs
VAR_OUTPUT
Done: BOOL;
Busy: BOOL;
Error: BOOL;
ErrorID: UDINT;
NumPointsRead: UDINT; (* return value <= NumPoints *)
END_VAR
Done | Becomes TRUE, if the data were read successfully. |
Busy | The Busy output becomes TRUE when the command is started with Execute and remains TRUE as long as the command is processed. When Busy becomes FALSE again, the function block is ready for a new command. At the same time one of the outputs, Done or Error, is set. |
Error | Becomes TRUE, as soon as an error occurs. |
ErrorID | If the error output is set, this parameter supplies the error number. |
NumPointsRead | The number of points that were actually read. The number may be less or equal NumPoints. |
