Set the read instruction code to Instruction code (RW
W2
) and turn Instruction code execution demand
(RY9) to “1” (ON). Turning RY9 to “1” (ON) sets the data corresponding to the preset read code to
Reading data (RW
R3
). Data are all hexadecimal numbers. At this time, Instruction code execution
completion (RX9) turns to “1” (ON) at the same time.
Read the read data set to RW
R3
while RX9 is “1” (ON). The data set to Reading data (RW
R3
) is held
until the next read instruction code is set and RY9 is turned to “1” (ON).
If the instruction code not in the specifications is set to Instruction code (RW
W2
), the corresponding
error code (
1 ) is set to Answer code. If any unusable parameter, position block or speed block is
read, the corresponding error code (
2 ) is set.
Turn Instruction code execution demand (RY9) to “0” (OFF) after completion of data read.
