These are outputs for the M, S, T and *B commands specified by
the part program at its execution in the automatic operation mode.
If any of M, S, T and *B commands is found at the execution of
the part program in the automatic operation mode, the control
outputs it in a BCD or binary code according to the value that
follows the detected command (M= 2 digits/3 digits, S = 2 digits, T
= 4 digits, *B = 3 digits).
Then, after the elapse of the time set in parameter (#6220), the
M, S, T and *B code reading outputs are closed.
NOTE
M code or MF code of M commands (M90 through M99)
in the logical circuit processing will not output.
(2)
M Decode (MOOR, MOIR, M02R, and M30R) Output
When any of M commands "MOO," "MO1 ," "M02," and "M30"
is executed, the corresponding decoded output "MOOR,"
"MOIR," "M02R," or "M30R" is output in addition to the M
code output and the M code reading output.
NOTE
When an M command for decoded output and a move
command are specified in the same block, the M code
output is provided at the start of the block, while the
decoded output is provided after completion of the move
command.
(3) M, S, T and *B Functions Completion (FIN) Inputs
These inputs give the completion of M, S, T and XCBcommands
to the control. When FIN input is closed while the M, S, T and
X B code reading (MF, SF, TF and XBF) outputs are closed,
they are opened. If FIN input is opened again after making sure
of their opening, the control assumes that the M, S, T or *B
command has been completed, starting the operation of the next
step.
NOTE
When
FIN input is closed then opened, the M code output
and the M decoded output are all opened, but the S, T and
*B code outputs remain as they are without change.

20.2.25 POSITIONING COMPLETION (DEN) OUT-
PUTS
These outputs inform the completion of a move command when an
M, S, T or *B command and the move command have been spec-
ified in the same block at the execution of a part program in the
automatic operation mode.
The block in which an M, S, T or *B command and a move
command are specified at the same time is executed, if the M, S, T
or *B command is not completed at the termination of the move
command, positioning completion output DEN is closed.
When FIN input is closed then opened and the M, S, T or XB
command is completed, the positioning completion outputs are
opened.
