Stage 2: Once processing is complete and the measurement data is available, the
parameters for pretransmit are set (e.g., 80 bytes as of MDT address 0x01C0) and
configured as a single transmit (see Chapter 6.4.2 “Pretransmit”). By this time,
the workpiece pallet has lowered. The SLK switches to CONNECTING and the MDT
immediately signs on and executes the pretransmit.

still active)
