Step numbers 0 to 15 (0 to F hex) are stored
for the steps for which execution has been
completed. Startup

(code) Board:
CIO 1910 bits 00 to
03 (port 1)
CIO 1920 bits 00 to
03 (port 2)
Unit:
n + 10 bits 00 to 03
(port 1)
n + 20 bits 00 to 03
(port 2)
Reception matrix case numbers 0 to 15 (0 to
F hex) are stored for which reception has
been completed. The number is cleared
when the sequence execution starts, when
the STUP(237) instruction is executed, and
at restarts.
The Executed Reception Case No. is stored
only when the reception matrix is set using
the RECV or SEND&RECV command. If a
reception matrix is not set, the case number
will be set to 0 (cleared) when another com-
mand is executed.

Flags Board:
CIO 1912 bits 00 to

CIO 1922 bits 00 to

Unit:
n + 12 bits 00 to 15
(port 1)
n + 22 bits 00 to 15
(port 2)
Reception matrix case numbers 0 to 15 for
which reception has been completed corre-
spond to individual bits (00 to 15), and are
turned ON to indicate execution. The num-
bers are cleared when the sequence execu-
tion starts, when the STUP(237) instruction
is executed, at restarts, and when the execu-
tion of each step starts.
The reception matrix case number can be
checked from the ladder program when the
WAIT command is executed or when the
sequence is ended after the reception matrix
RECV command is executed.
The Executed Reception Case No. Flag in
the bit corresponding to the stored case
number will be turned ON only when the
reception matrix is set for the RECV or
SEND&RECV command. If a reception
matrix is not set, the case number will be set
to 0 (cleared) when another command is
executed.

Flags Board:

(port 2)
Case numbers 0 to 15 for the steps for which
execution has been completed correspond to
individual bits (00 to 15), and are turned ON
in ascending order. Once a bit has been exe-
cuted, the bit corresponding to the executed
step is turned ON in ascending order to hold
the bit ON during the sequence (and after
completion). Startup
