16422
Write device data to
intelligent function
module/special
function module
(TO) execution error
• Number of words (n) to be written is outside the
range of 1 to 256.
• Motion CPU cannot communicate with
intelligent function module/special function
module at the instruction execution.
• Abnormalities of the intelligent function module/
special function module were detected at the
instruction execution.
• I/O No.s specified with (D1) differ from the
intelligent function module/special function
module controlled by the self CPU.
• The address specified with (D2) is outside the
buffer memory range.
• First 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 the device number is not
a multiple of 16.
• PX/PY is set in (S) to (S)+(n-1).
• Correct the program so that the number of
words (n) to be written is within the range of 1
to 256.
• Replace the intelligent function module/
special function module if there is a fault.
• Correct the program so that the first I/O No.s
specified with (D1) is intelligent function
module/special function module controlled by
the self CPU.
• Correct the program so that the address
specified with (D2) is within the buffer
memory range.
• Correct the program so that first 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.
16423
Read device data
from intelligent
function
module/special
function module
(FROM) execution
error
• Number of words (n) to be read is outside the
range of 1 to 256.
• Motion CPU cannot communicate with
intelligent function module/special function
module at the instruction execution.
• Abnormalities of the intelligent function module/
special function module were detected at the
instruction execution.
• I/O No.s specified with (S1) differ from the
intelligent function module/special function
module controlled by the self CPU.
• The address specified with (S2) is outside the
buffer memory range.
• First 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 the device number is not
a multiple of 16.
• PX/PY is set in (D) to (D)+(n-1).
• Correct the program so that the number of
words (n) to be read is within the range of 1 to
256.
• Replace the intelligent function module/
special function module if there is a fault.
• Correct the program so that I/O No.s specified
with (S1) is intelligent function module/special
function module controlled by the self CPU.
• Correct the program so that the address
specified with (S2) is within the buffer memory
range.
• Correct the program so that first 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.

Indirectly specified
16-bit motion device
(#(n)) read error
• The indirectly specified device No. is outside
the range.
16463
Indirectly specified
32-bit motion device
(#(n)L) read error
16464
Indirectly specified
64-bit motion device
(#(n)F) read error
• The indirectly specified device No. is outside
the range or an odd number.
16465
Indirectly specified
16-bit data register
(D(n)) read error
• The indirectly specified device No. is outside
the range.
16466
Indirectly specified
32-bit data register
(D(n)L) read error
16467
Indirectly specified
64-bit data register
(D(n)F) read error
• The indirectly specified device No. is outside
the range or an odd number.
The block processing in
execution is stopped and
the next block is executed.
Correct the program so that the indirectly
specified device No. is proper.
