Appendix 5 Accuracy of D/A Conversion
Appendix 5 Accuracy of D/A Conversion
The accuracy is measured for the maximum analog output value.
Even if the offset/gain setting or output range is changed to change output characteristics, the accuracy remains the
same, and is kept within the range described in performance specifications.
The following graph shows the variation range of the accuracy for the 0 to 5V range.
When the operating ambient temperature is 25±5°C, an analog value is output with the accuracy within ±0.2%
(±10mV) and when the operating ambient temperature is 0 to 55°C, ±0.3% (±15mV). (Note that this will not apply when
the D/A converter module is influenced by noise.)
Appendix 6 Conversion Speed of D/A Conversion
The conversion speed is the time for D/A-converting CH Digital value (RWw2 to RWw5) and outputting the converted
analog output value actually.
However, the CC-Link IE Field Network system requires additional time for data link processing. Therefore, the time of
the cycle to output the analog output value actually is calculated by the following formula.
Data link processing time = SM + LS + Remote device station processing time [ms]
For details on the data link processing time, refer to the following.
User's manual for the master/local module used
SM : Scan time of the program in the master station
LS : Link scan time

When the operating ambient
temperature is 25 5 , the value
varies within 0.2% ( 10mV).
When the operating ambient
temperature is 0 to 55 , the value
varies within 0.3% ( 15mV).
