Analog I/O (XA CPU Units) Section 5-5
0 to 5 V Outputs
When the resolution is set to 1/6,000, the hexadecimal values 0000 to 1770 (0
to 6,000) correspond to an analog voltage range of 0 to 5 V.
When the resolution is set to 1/12,000, the hexadecimal values 0000 to 2EE0
(0 to 12,000) correspond to an analog voltage range of 0 to 5 V. The entire
output range is −0.25 to 5.25 V.
Specify a negative voltage as a two’s complement.
The following diagram shows conversion values for 1/6,000 resolution.
1 to 5 V Outputs
When the resolution is set to 1/6,000, the hexadecimal values 0000 to 1770 (0
to 6,000) correspond to an analog voltage range of 1 to 5 V.
When the resolution is set to 1/12,000, the hexadecimal values 0000 to 2EE0
(0 to 12,000) correspond to an analog voltage range of 0 to 5 V. The entire
output range is 0.8 to 5.2 V.
The following diagram shows conversion values for 1/6,000 resolution.
0 to 20 mA Outputs
When the resolution is set to 1/6,000, the hexadecimal values 0000 to 1770 (0
to 6,000) correspond to an analog current range of 0 to 20 mA.
When the resolution is set to 1/12,000, the hexadecimal values 0000 to 2EE0
(0 to 12,000) correspond to an analog current range of 0 to 20 mA. The entire
output range is 0 to 21 mA.
