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.
No.

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

(auto reconnect is
still active)
