JP/GP.SREAD (Data Read from Programmable
Controllers on Other Stations)
The SREAD instruction 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 reading is completed. (The other station
can recognize that data have been read out with the SREAD instruction.)

*2 The SREAD instruction can be programmed without argument (D3).
However, in such a case, the operation is identical to the READ instruction.
With the SREAD instruction, different operations are available depending on whether (D3) is omitted or not.
*3 When the target station is a Basic model QCPU or safety CPU, the read notification device set as argument (D3) for the
target station is ignored. (Same operation as with the READ instruction)
*4 If the device setting in the PLC parameter is different between the own and target stations, use "(S2)" (with double
quotation marks) to specify.
