(Note-1) : The device No. cannot be specified indirectly.
(Note-2) : Specify a multiple of 16 as the device number of bit data.
(Note-3) : Special relays (M9000 to M9255) and dedicated devices (M2000 to M2399) cannot be set.
(Note-4) : PX and PY cannot be set.
(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) The following analogue modules can be used as the control module of Motion
CPU.
• Q62DA
• Q64DA
• Q68DAV
• Q68DAI
(1) An operation error will occur if:
• 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 device number is not a multiple of 16.
• PX/PY is set in (D) to (D)+(n-1).
