NOTES
'Arrived' is transmitted if the next conveyor has recognized the board and thus the board
transfer is completed. The 'released' signal is taken back and a new board transfer can be
started.

This signal informs the next conveyor that a board is present which can be 'released'. The
signal is always active when a board is available and the previous board transfer was
completed.
This signal is the absolute condition for the turning on of the transport belts. If a
'permission' exists and a 'request' is present, the board transfer can start. If a 'permission'
is taken back during the transfer, the handling must be interrupted, (stop the transport
belts).
If a board was 'released' to the next conveyor, this signal is set and the 'request' taken
back. The signal remains active until the next conveyor transmits the acknowledgement
'arrived'. During the transport, this signal informs the next conveyor that a board is on
the way.
