3.6.2 Instruction codes
(1) Read instruction codes (0000h to 0A1Fh)
Instruction code
(RWwn+2)
Data read period
Instruction code
execution demand
(RYn9)
Instruction code
execution completion
(RXn9)
Reading data
(RWrn+3)
Respond 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 ) is set to respond code. If any unusable parameter, point table is read, the corresponding
error code (
2 ) is set.
Turn Instruction code execution demand (RYn9) to OFF after completion of data read.
