Write buffer memory
data to head module
(RTO) execution error
• Number of words (n) to be written is
outside the range 1 to 240.
• The SSCNET
/H head module axis No.
specified with (D1) is outside the range 1
to 8.
• The SSCNET
/H head module is not
connected at the instruction execution.
• Start device No. (S) which writing data are
stored + number of words (n) to be written
is outside the device range.
• (S) is a bit device and device number is
not a multiple of 16.
• PX/PY is set in (S) to (S)+(n-1).
• RTO instruction was executed again
before RTO instruction is executed and
complete bit is turned on.
The block processing
in execution is
stopped and the next
block is executed.
• Correct the program so that number of
words (n) to be written is within the range 1
to 240.
• Correct the program so that the
SSCNET
/H head module axis No.
specified with (D1) is within the range 1 to
8.
• Connect the SSCNET
/H head module.
• Correct the program so that start device No.
(S) which writing data are stored + number
of words (n) to be written is within the
device range.
• When (S) is a bit device, set the device
number to be multiple of 16.
• When (S) is a bit device, do not set PX/PY.
• Execute RTO instruction again after the
complete bit of RTO instruction is turned on.

Read buffer memory
data from head
module (RFROM)
execution error
• Number of words (n) to be read is outside
the range 1 to 240.
• The SSCNET
/H head module axis No.
specified with (S1) is outside the range 1
to 8.
• The SSCNET
/H head module is not
connected at the instruction execution.
• Start device No. (D) which stores the
reading data + number of words (n) to be
read is outside the device range.
• (D) is a bit device and device number is
not a multiple of 16.
• PX/PY is set in (D) to (D)+(n-1).
• RFROM instruction was executed again
before RFROM instruction is executed and
complete bit is turned on.
• Correct the program so that number of
words (n) to be read is within the range 1 to
240.
• Correct the program so that the
SSCNET
/H head module axis No.
specified with (S1) is within the range 1 to
8.
• Connect the SSCNET
/H head module.
• Correct the program so that start device No.
(D) which stores the reading data + number
of words (n) to be read is within the device
range.
•When (D) is a bit device, set the device
number to be multiple of 16.
• When (D) is a bit device, do not set PX/PY.
• Execute RFROM instruction again after the
complete bit of RFROM instruction is turned
on.
