The operation mode is selected with the operation mode A set command or
operation mode B set command.
The following four items can be selected for the Unit with the operation mode
A set command.
• Data Input
Measurement Mode or Comparison Mode:
When the Unit is in measurement mode, the binary-coded scaled conver-
sion data is stored in the input word allocated to the Unit. When the Unit is
in comparison mode, the Comparison Result Flags of the input word allo-
cated to the Unit are turned ON or OFF after comparing the set value and
scaled conversion data. When any overrange or sensor disconnection is
detected by the Unit, the Overrange or Sensor Disconnection Flag of the
input word is turned ON. The measurement mode is the factory setting.
• Timing Hold
Normal, Sampling Hold, Maximum Hold, Minimum Hold, Peak-to-
peak Hold:
When setting the initial values, one of the five timing holds can be
selected for the Unit. The timing hold is factory-set to normal.
• Input Type
9.999 V, 5 V, 1 to 5 V, or 4 to 20 mA:
When setting the initial values, any input type among four input types can
be selected for the Unit. The 9.999 V input type is the factory setting.
• Monitor Output (CQM1-LSE02 Only)
Scaled Conversion Data Monitor Mode or Set Data D/A Output Mode:
The CQM1-LSE02 has a monitor output terminal, to which simple moni-
toring devices, such as the K3TE Digital Panel Meter, can be connected.
In the scaled conversion data monitor mode, the Unit outputs the voltage
corresponding to the scaled conversion data. In the set data D/A output
mode, the monitor output terminal has voltage output corresponding to
the data which is written to the output word allocated to the Unit. The
scaled conversion data monitor mode is the factory setting.
It is possible to select any of the following three items for the Unit with the
operation mode B set command.
• Input Sampling Speed
Fast or Slow:
The sampling time and period can be set to fast or slow according to the
type of sensing object considering the relationship between the measur-
ing accuracy and measuring speed. The sampling time/period is factory-
set to slow.
• Number of Averaging Process Times
1, 2, 4, 8, or 16:
For more precise sampling, it is possible to take an average of a desig-
nated number of samples. The number is factory-set to 4.
