Monitor Output

The present scaled conversion data can be read in BCD only when the timing
hold in operation mode A is set to normal.
Use the present value read command and take the following steps to read the
present scaled conversion data in BCD with the Programming Console.
1. Set CC00 to the output word.
2. A000, which means positive, or A00F, which means negative, will appear
under the input word display according to the present scaled conversion
data.

3. The present scaled conversion data will appear in approximately 0.5 se-
conds.
4. A000 or A00F will appear according to the present scaled conversion data in
approximately 0.5 seconds.
5. While CC00 is set to the output word, the A000 or A00F and the present
scaled conversion data will be repeatedly displayed alternately at approxi-
mately 0.5-s intervals.
6. Set 0000 to the output word again to cancel reading the present scaled con-
version data in binary.

The CQM1-LSE02 has a monitor output function.
The CQM1-LSE02 can be in scaled conversion data monitor mode or set data
D/A output mode, either of which can be selected with the operation mode A set
command.
The CQM1-LSE02 in scaled conversion data monitor mode does not require
special operation settings. Refer to the following to operate the CQM1-LSE02 in
set data D/A output mode.
In this mode, the monitor output terminal of the CQM1-LSE02 will have voltage
output corresponding to the scaled conversion data which is written in the output
word allocated to the Unit. Therefore, the ladder program enables the
CQM1-LSE02 to output an analog input signal as a desired voltage value.
