# Display data of tool centre point in MCS

Tool centre point position (MCS)
Description | Command position of tool centre point in machine coordinate system MCS. The value is refreshed in each interpolation cycle.
Signal flow | CNC → PLC
ST path | gpCh[channel_idx]^.bahn_state.coord_r[axis_idx].w0_position_r
Data type | DINT
Unit | [0.1 µm]
Access | PLC is reading

Velocity at tool centre point (MCS)
Description | Velocity value of tool centre point in machine coordinate system MCS. The value is refreshed in each interpolation cycle.
Signal flow | CNC → PLC
ST path | gpCh[channel_idx]^.bahn_state.coord_r[axis_idx].w0_velocity_r
Data type | DINT
Unit | [0.1 µm/s]
Access | PLC is reading

Acceleration at tool centre point (MCS)
Description | Acceleration value of tool centre point in machine coordinate system MCS. The value is refreshed in each interpolation cycle.
Signal flow | CNC → PLC
ST path | gpCh[channel_idx]^.bahn_state.coord_r[axis_idx].w0_acceleration_r
Data type | DINT
Unit | [0.1 µm/s²]
Access | PLC is reading
