3. Specification of Analog I/O Data
• When the analog I/O board is installed, be sure to specify the data within the range of K0 to K255 (using 8 bits) as
follows:
Example:
If K-1 is set to special data register DT9096, analog data, being regarded as K255, is output.
Note:
• When the A/D converter board or D/A converter board is installed, be sure to specify the data within the range of K0 to
K999 (using 10 bits) as follows:
Example:
If K1,024 is set to special data register DT9096, analog data, being regarded as 0, is output.
Notes:
• If data outside K0 to K1,023 is specified, the data is handled ignoring data in bit positions 10 to 15.
• If data K1,000 to K1,023 is specified, analog data that is slightly more than the maximum rated value
(5 V, 10 V, and 20 mA) is output.
Data in bit positions 10 to 15 is ignored.
