WECON Technology Co., Ltd.
The output analog of all channels
（
-10V~10V
）
is stored inside the data memory
（
D8112, D8113
）
in the form of data. Values will be automatically stored when the “END” order is sent out. The value
is calculated by the designated analog data conversion characteristics of the special auxiliary relays
M8112 and M8113.
6.1 Basic Program Examples
Caution
1)
Start M8112 and M8113; designate the analog data conversion characteristics of CH1 and CH2.
2)
After execution of analog data conversion, do not change the values of D8112 or D8113
through operator program, programming tools or graphic operating terminal.
3)
The following program will be set into voltage output mode, and the data of D0 and D2 will be
converted into analog value.
If the data are not stored into D0 or D2
，
then D8112, D8113 can be simultaneously used on setting
values and other orders, such as timer/counter.
6.2. Examples of Applications
Since the LX3V-2DAV-BD does not have offset and gain functions, if it needs for the values out of
the standard specifications, Additional programming orders will be needed to multiply or divide the
converted value.
Caution
1)
Since the use of additional programming orders, the converted precision and resolution of the
analog value are different with the specifications;
2)
The original range of the analog output does not change;
Voltage Output Mode
1)
Under the voltage output mode, the 2DAV will convert the figures -2000~2000 into analog
output -10V~10V. If the figure data used in the application is -A~A, then the range must be
Set CH1, CH2 into voltage output mode
(-10V~10V)
Set the digital value of D0 into analog value
Set the digital value of D2 into analog value
