Description of the reference program
Rung1 : This starts Read Request and starts reading.
Rung2 : With the rising of Result Complete, the data written to Result Data are
copied to READ_DATA.
Rung3 : When Read Complete is ON, Read Complete Clear turns ON.

Reference program chart
Description of the reference program
Row 1 : When the timing (REQ) signal turns ON, Read Request turns ON.
Row 2 : When Read Data Reception Available turns ON and Read Data
Reception Complete turns OFF, Read Data Update Permitted turns ON.
Read Data Update Permitted is self-retained.
* Read Data Reception Available turns ON when read data is buffered
to SR-750.
Row 3 : When Read Data Reception Complete turns ON, the data for the
specified bytes are transferred from read data to DM1000.
* Read Data Reception Complete turns ON when writing read data from
SR-750 to PLC is complete.
Row 4 : When Read Complete is ON, Read Complete Clear turns ON.
