SLK operation
Stage 1: Once an MDT enters the HF field, the MDT status (triggers TPDO2) and
the data in transfer buffer 0 mapping are read. If the data in the transfer buffer is
available, the SLK sends a TPDO4 with the appropriate status information.
Stage 2: The lift unit moves the workpiece pallet into processing position. The
measurement data obtained in the application is entered in transfer buffer 1, the
buffer is switched to pretransmit mode and auto mode is set to reconnect. Once the
lift unit returns the MDT to the position in front of the SLK, the system switches to
CONNECTING. The data in transfer buffer 1 is automatically entered after the MDT
signs on.
No. Action
1 Wait until transfer buffer 0 status is
"Data exchange complete".
2 MDT communication is terminated by
auto disconnect and the HF field is off.
The lift unit can move the workpiece
pallet into processing position
3 Transfer buffer 0 can be read at the
same time
4 Once the measurement data from pro-
cessing is available, enter it into transfer
buffer 1.
5 Switch transfer buffer 1 to "single trans-
mit" pretransmit mode and activate
6 Switch auto mode register to auto
reconnect
7 Wait until lift unit is in lower position
8 Make SLK ready to receive
(CONNECTING)
9 Wait until transfer buffer 1 status is
"Data exchange complete".
10 Switch the auto mode register to auto
disconnect and allow the workpiece
pallet to continue
