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.)

[Instruction

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.

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)

If the device setting in the PLC parameter is different between the own and target stations, use "(S2)" (with double

quotation marks) to specify.
