■Applicable devices

*1 FX and FY cannot be used.

*2 FD cannot be used.

*3 T, ST, C, and FD cannot be used.

• The SREAD instruction cannot be executed when the target station is ACPU.

• Specify the own station start device (d1) for storing the data that has been read, by considering the range in

which the data that has been read can be stored.

(Example: When areas D150 and after in the own station CPU module are already in use)

• When the target station for which the SREAD instruction is executed is the Basic model QCPU, the read

notification device for the target station specified by argument (d3) is ignored. The operations of the SREAD

instruction are the same as those of the READ instruction.

• The SREAD instruction can be programmed by omitting argument (d3). However, the operations are the

same as those of the READ instruction. The operations of the SREAD instruction can be selected according

to whether (d3) is omitted or not.
