MC_SetCoordinateTransform

This Function Block sets a coordinate transformation between the MCS and PCS.

  • CoordTransform refers to a coordinate transformation including the parameters. The details of the transformation and of the parameters are outside the scope of PLCopen.
  • The system may supports a neutral transformation. With activating the neutral transformation the axes are referenced in the MCS system again.
  • The Transformation could as well be dynamic.
  • This Function Block does not start a movement (administrative Function Block). The movement is initiated by a command in PCS.

The transformation will be activated on the next group movement, e.g. MC_MoveLinearAbsolute. When the block is activated, it first will be “Busy”. The Group will activate the transformation on the next movement, the block changes to “Done”. The transformation will be used until an other transformation is activated.

This Function Block is only supported for PLC-based central Motion Control with Coordinated Motion structures.
