Jn Local station network number
Start I/O signal of the local station network module/Ethernet
module.
Un
Designate by higher two digits when the I/O signal is
expressed by three digits.
Control data storage head device
(S1) Designate the head device of the local station that stores
the control data.
Read data storage head device (target station)
(S2) Designate the head device of the target station that stores
the data to read.
Read data storage head device (local station)
(D1) Designate the head device of the local station that stores
the data to read.
Read completion device (local station)
Designate the device of the local station to turn on one
scan when the read is complete.

Read notify device (target station)
Designate the device of the target station to turn on one
scan when the read is complete.

1 The SWRITE instruction can be programmed without argument (D3).
However, in such a case, the operation is identical to the WRITE instruction.
With the SWRITE instruction, different operations are available depending on whether (D3) is omitted
or not.
2 When the target station is a Basic model QCPU or safety CPU, the write notification device set as
argument (D3) for the target station is ignored. (Same operation as with the WRITE instruction)
