(3) When data are read normally from the target CPU specified with (S1), the reading
complete flag SM528 to SM531 (CPU No.1 : SM528, CPU No.2 : SM529, CPU
No.3 : SM530, CPU No.4 : SM531) corresponding to the target CPU turns on. If
data cannot be read normally, the reading complete flag of the target CPU does
not turn on.
(4) Adjust an executive task, the number of transfer word referring to the operation
processing time so that this instruction may not obstruct the execution of the
motion operation because processing time becomes long in argument to the
Number of words (n) to be read.
(5) When multiple MULTR instructions are executed to the same CPU simultaneously,
the reading complete flag SM528 to SM531 turns on/as a result of MULTR that it
is executed at the end.
(6) Reset the reading complete flag (SM528 to SM531) using the user program.
(1) An operation error will occur if:
• Number of words (n) to be read is outside the range of 1 to 256.
• The CPU shared memory first address (S2) of the data which it will be read is
outside the range (000H to FFFH) of the CPU shared memory address.
• The CPU shared 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
CPU shared memory address.
• Start 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 CPU which reads is resetting.
• The errors are detected in the CPU which read.
• (D) is a bit device and device number is not a multiple of 16.
• PX/PY is set in (D) to (D)+(n-1).
