Analog I/O (XA CPU Units)
Section 5-5
Shared I/O Specifications
Analog I/O Signal
Ranges
Analog I/O data is digitally converted according to the analog I/O signal range
as shown below.
Note
When the input exceeds the specified range, the AD converted data will be
fixed at either the lower limit or upper limit.
Analog Input Signal
Ranges
−
10 to 10 V Input
When the resolution is set to 1/6,000, the
−
10 to 10-V range corresponds to
hexadecimal values F448 to 0BB8 (
−
3,000 to 3,000). The entire data range is
F31C to 0CE4 (
−
3,300 to 3,300).
When the resolution is set to 1/12,000, the
−
10 to 10-V range corresponds to
hexadecimal values E890 to 1770 (
−
6,000 to 6,000). The entire data range is
E638 to 19C8 (
−
6,600 to 6,600).
A negative voltage is expressed as a two’s complement.
The following diagram shows conversion values for 1/6,000 resolution.
0 to 10 V Input
When the resolution is set to 1/6,000, the 0 to 10-V range corresponds to
hexadecimal values 0000 to 1770 (0 to 6,000). The entire data range is FED4
to 189C (
−
300 to 6,300).
Resolution
