If there is no board B when a carry out command is issued,
Ready OUT to the previous stage is set off (Busy).
[Key operation]
Operation by the board carry out command is effective only on the board
currently set in the centering station. It is not effective on the board to be
carried in from the IN buffer.

[Key operation]
The status that the WAIT sensor is set on is reliable. Therefore, when th
e
WAIT sensor is set on, the IN buffer is set in "board loaded" condition eve
n
if the board is not carried into the IN buffer. However, this status is not
latched and if board B is removed during production of board A, the IN
buffer is set in "board unloaded" condition.

There is no latch status for the OUT buffer such as for the IN buffer,
and detection is made simply by on and off of the OUT sensor.
