Error cause
Write device data to shared CPU memory
(MULTW) execution error
• Number of words (n) to be written is outside
the range of 1 to 256.
• The shared CPU memory address (D) of self
CPU of the writing destination device is outside
the range (800H to FFFH) of the shared CPU
memory address.
• The shared CPU memory address (D) of self
CPU of the writing destination device + number
of words (n) to be written is outside the range
(800H to FFFH) of the shared CPU memory
address.
• First device No. (S) which writing data are
stored + number of words (n) to be written is
outside the device range.
• MULTW instruction was executed again before
MULTW instruction is executed and complete
bit device is turned on.
Read device data from shared CPU memory of
the other CPU (MULTR) execution error
• Number of words (n) to be read is outside the
range of 1 to 256.
• The shared CPU memory first address (S2) of
the data which it will be read is outside the
range (000H to FFFH) of the shared CPU
memory address.
• The shared CPU memory first address (S2) of
the data which it will be read + number of
words (n) to be read is outside the range
(000H to FFFH) of the shared CPU memory
address.
• First device No. (D) which stores the reading
data + number of words (n) to be read is
outside the device range.
• Except 3E0H/3E1H/3E2H/3E3H is set at (S1).
• The self CPU is specified with (S1).
• The CPU which reads is resetting.
• The errors are detected in the CPU which read.

• Correct the program so that the
number of words (n) to be written is
within the range of 1 to 256.
• Correct the program so that the
shared CPU memory address (D) of
self CPU of the writing destination is
within the range of shared CPU
memory address.
• Correct the program so that the
shared CPU memory address (D) of
self CPU of the writing destination +
number of words (n) to be written is
within the range of shared CPU
memory address.
• 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.
• Execute MULTW instruction again
after the complete bit device of
MULTW instruction is turned on.

shared CPU memory first address
program
(S2) of the data which it will be read is
ends
within the range of shared CPU
memory address.
• Correct the program so that the
shared CPU memory first address
(S2) of the data which it will be read +
number of words (n) to be read is
within the range of shared CPU
memory address.
• 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.
• Correct the program so that
3E0H/3E1H/3E2H/3E3H is set at
(S1).
• Correct the program so that the self
CPU is not specified with (S1).
• Check that the reset flag (M9240 to
M9243) is OFF, then correct the
program to execute the MULTR
instruction.
• If the errors are detected in the CPU
which read, exchange the CPU.
