M-code
ON
signal is OFF.
Then, M-code data (BFM
#5) is generated and the
M-code
ON
signal turns
ON.
After the aux. device
operation is completed,
unless the M-code
ON
signal is turned OFF by
an M-code OFF com-
mand (BFM #1
b5)
etc.,
the next WAIT MO, WAIT
M,
or SET M instruction
is
not
executed, and the
wait state remains
ON.
(M-code
ON
signal OFF
wait state)
When
a
WAIT
MO
or
WAIT
M
instruction
is
executed, the
READY signal
the START
turns
ON
and
command wait
state is set.
(AFTER mode)
When a START com-
mand is given, the M-
code
ON
signal is
c
turned OFF automat-
ically
in
the PGU.
After the M-code
ON
signal is turned OFF,
+
give a START com-
mand.
When an M-code
OFF command is
turned
ON,
the opera-
+-
tion starts automat-
ically.
The READY signal does not turn
ON,
and the operation goes
to
the next step
without a START command.
(WITH mode)
However, if a WAIT MO, WAIT
M,
or
SET
M
instruction exists in the next
step, the wait state is set until the
M-
code
ON
signal
is
turned OFF.
