Description
Reference
section
Read from/write to
other station devices
(for Q/QnA series)
READ
Reads data from devices of a programmable controller on another station. (In
units of words)
Section 9.3
SREAD
Reads data from devices of a programmable controller on another station. (In
units of words)
With the SREAD instruction, a device on another station turns ON when data

Section 9.5
SWRITE
Writes data to devices of a programmable controller on another station. (In units
of words)
*2
With the SWRITE instruction, a device on another station turns ON when data
writing is completed. (The other station can recognize that data have been written
with the SWRITE instruction.)
