1 : The number of points to be read should be within the appropriate range:
• In case of a Q series CPU
1 (number of bit device number of word device points
+ number of double - word device points) 192 points
• In case of a QnA series CPU
1 (number of bit device number of word device points
+ number of double - word device points) 96 points
Note that for ZR devices the number of points that can be read should be multiplied by 2.
