Example of Scaling into the Data between 0000 to 5000 for the Input
between 4 to 20 mA
When the input is 12 mA, the scaled conversion data becomes 2500 and the
output voltage that corresponds to this value becomes 2.5 V.

In this mode, the monitor output terminal of the CQM1-LSE02 will have volt-
age output corresponding to the signed binary data stored in the output word
of the CQM1-LSE02 by easy use of the ladder program.
The signed binary data range of the CQM1-LSE02 is from –9999 (D8F1) to
9999 (270F) and the voltage output range of the CQM1-LSE02 corresponding
to the signed binary data range is from –9.999 to 9.999 V.
If the signed binary data out of the range is stored in the output word, either
–9.999 or 9.999 V will be output. For example, if the signed binary data D8F0
(–10000 in BCD) is written, the voltage of the monitor output will be –9.999 V.
Note In case of using the Unit in the set data D/A output mode, when obtaining the
value to be set to the output word through calculation using the ladder pro-
gram, etc., be careful not to use the computed result of "C000 to CFFF." Even
when the Unit is used in the set data D/A output mode, if "C000 to CFFF" is
set to the output word, it is treated as a command.
In this mode, analog input is converted into digital data and then converted
into analog output. Therefore, the obtained analog output is not highly precise.
