Data read period
Set the data to be read to Instruction code (RWw2) and turn on Instruction code execution demand (RY9).
Turning on RY9 sets the data corresponding to the set read code to Read the data (RWr3). Data are all in
hexadecimal.
At this time, Instruction code execution completion signal (RX9) turns on simultaneously. Read the read
data set to RWr3 while RX9 is on.
If the instruction code set to Instruction code (RWw2) does not exist in the specifications, an error code
(
1 ) is set to Answer code. If unusable parameter/point data is read, an error code ( 2 ) is set.
Turn off Instruction code execution demand (RY9) after completion of data read.
