See Section 4.2.2 for the allowable specification range. Processing code • Specify 516 (&H204). Specify the number of points for the word device (lower digit) or bit device (higher digit) to be read. 1 Specify the number of double-word device points to be read. 1 Fixed value • Specify 0 (&H0). Specify the device using the defined code. • See Section 4.2.5 for the code numbers. Specify the device number (lower digit) of the specified device. See Section 4.2.5 for the allowable specification range. Specify the device number (higher digit) of the specified device. See Section 4.2.5 for the allowable specification range. Specify the device processing unit. • • • • 0 (&H0) • When reading in bit units • When reading word devices • • • • 0 (&H0) in word/double - word units • When reading bit devices in word units • • • • 8960 (&H2300) • When reading bit devices in double - word units • • • • 9984 (&H2700) Fixed value • Specify 0 (&H0). 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 points + 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 points + 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. 11 - 219 11 - 219
