# Display on the HLI

The input and output values of the dynamic coordinate system can be displayed on the HLI.

Display of coordinate system positions to the PLC

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
Unit | 0.1 µm
ST path | gpCh[channel_idx]^.bahn_state.coord_r[axis_idx].w0_position_r
Data type | DINT
Access | PLC is reading

## Notice

For the purpose of compatibility, display of the w0_position_r must be activated in the channel list by P-CHAN-00145 (kin_trafo_display = 1).

Dynamic CS 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
Unit | 0.1 µm
ST path | gpCh[channel_idx]^.bahn_state.coord_r[axis_idx].position_dyncs_r
Data type | DINT
Access | PLC is reading
