MC_PATH_DATA_REF

MC_PATH_DATA_REF represents the path to be executed by MC_MovePath, whereby the number of entries is limited to 30. The path to be executed is written by MC_MoveLinearAbsolutePreparation, MC_MoveCircularAbsolutePreparation and MC_BlockerPreparation. It is initialized with a pointer to a user defined buffer. Hereby the user can define the size of the path. The initialization has to be done during declaration. The path table is not reset at execution. To reset, the method ClearPath must be called.

Sample

The example below shows how to declare a path reference and how to reset an existing path.

VAR
    buffer          : ARRAY[1..4096] OF BYTE;
    Path            : MC_PATH_DATA_REF(ADR(buffer), SIZEOF(buffer));
END_VAR

//delete all segments of path table
Path.ClearPath();

The data type MC_PATH_DATA_REF is part of the Motion Control (MC) library. Use the method ClearPath() to clear path information of type MC_PATH_DATA_REF and thus to reset an existing path. Use only Motion Control functions or Motion Control function blocks on the data type MC_PATH_DATA_REF. In particular, do not use any storage functions such as MEMCMP, MEMCPY, MEMSET or MEMMOVE with data type MC_PATH_DATA_REF.
