Stage 2: If measurement data is available during processing, 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.

6 Wait until event counter in event-oriented data channel increases by 1. At this time, the
measurement data is written to the MDT and the link is DISCONNECTED (auto reconnect is
still active)
