MELSEC-Q
6 DEDICATED INSTRUCTIONS
POINT
(1) The SWRITE instruction can be executed only when the target station is a
Q/QnACPU.
(The SWRITE instruction cannot be executed for an ACPU connected to the
MELSECNET/10 or Ethernet network system.) Thus, the target station number
should be limited to the Q/QnACPU station numbers.
(2) When writing data from the other station CPU module device with the SWRITE
instruction, specify the device within the range applicable to the host station
CPU module.
(Head device number to be write in other station CPU module (S2)) + (number
of write points -1)
< (last device number of host station CPU module )
: Last device number in host station CPU module having the same device
name as (S2).
(3) When the target station of the SWRITE instruction is the Q00J/Q00/Q01CPU,
the write notify device for the target station that is set by an argument (D3) is
ignored. The operation of the SWRITE instruction is identical to that of the
WRITE instruction.
(4) The SWRITE instruction can be programmed without the argument (D3), while
the operation is identical to that of the WRITE instruction. Depending on
whether D3 is omitted or not, the SWRITE instruction can be operated
differently.
