(RWrn+3)
Answer code
(RWrn+2)
Set the read instruction code (refer to Section 3.5.4 (1)) to Instruction code (RWwn+2) and turn
Instruction code execution demand (RYn9) to ON. Turning Instruction code execution demand (RYn9)
to ON sets the data corresponding to the preset read code to Reading data (RWrn+3). Data are all
hexadecimal numbers. At this time, Instruction code execution completion (RXn9) turns to ON at the
same time.
Read the read data set to Reading data (RWrn+3) while Instruction code execution completion (RXn9)
is ON. The data set to Reading data (RWrn+3) is held until the next read instruction code is set and
Instruction code execution demand (RYn9) is turned to ON.
If the instruction code not in the specifications is set to Instruction code (RWwn+2), the corresponding
error code ( 1
