MELSEC-Q
6 DEDICATED INSTRUCTIONS
POINT
(1) The READ instruction can be executed only when the target station is the
Q/QnACPU.
(The READ instruction cannot be executed for an ACPU connected to the
MELSECNET/10 or Ethernet network systems.)
Thus, the target station numbers should be limited to Q/QnACPU station
numbers.
(2) When reading data from the other station CPU module device with the READ
instruction, specify the device within the range applicable to the host station
CPU module.
(Head device number to be read in other station CPU module (S2)) + (number
of read 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).
REMARK
1) 1: At completion of the execution of an instruction, the completion status ((S1) +
1) and the clock data ((S1) + 11 to (S1) + 17) at error occurrence are stored
in the control data.
2) The number of steps for the READ instruction is 9.
