MC_ReadMotionFunction
The MC_ReadMotionFunction function block 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_VARName | Type | Description |
|---|---|---|
Execute | BOOL | The command is executed with a rising edge at Execute input. |
CamTableID | MC_CAM_ID | ID of the loaded table. |
PointID | MC_MotionFunctionPoint_ID | Point ID of the first point of the motion function to be read. |
NumPoints | UDINT | 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. |
Inputs/outputs
VAR_IN_OUT
CamTable : MC_CAM_REF;
END_VARName | Type | Description |
|---|---|---|
CamTable | MC_CAM_REF | Reference to the table (structure). |
Outputs
VAR_OUTPUT
Done : BOOL;
Busy : BOOL;
Error : BOOL;
ErrorID : UDINT;
NumPointsRead : UDINT; (* return value <= NumPoints *)
END_VARName | Type | Description |
|---|---|---|
Done | BOOL | Becomes TRUE if the data have been read successfully. |
Busy | BOOL | The Busy output becomes TRUE when the command is started with Execute and remains TRUE for as long as the command is processed. If Busy becomes FALSE again, the function block is ready for a new order. At the same time one of the outputs, Done or Error, is set. |
Error | BOOL | Becomes TRUE as soon as an error occurs. |
ErrorID | UDINT | If the error output is set, this parameter supplies the error number. |
NumPointsRead | UDINT | The number of points that were actually read. The number can be less than or equal to NumPoints. |
