LX3V-2ADV-BD
1 WECON Technology Co., Ltd.
1.Mounting instruction
Before the installation make sure that the PLC host and the equipment connected to BD module
have been powered off. Please install the BD module in the corresponding position of the PLC, and
lock the two standard screws.
Caution:
1) This BD module only support the following firmware versions or later. Users can check the PLC
firmware version in D8001.
LX3VP:25103;
LX3VE: 25201;
LX3V-A2:25014;
LX3V-A1: 22006;
When mounting module to PLC, all the lights are blinking after power ON PLC please purchase a
new PLC.
2) Please fixed BD module on the PLC, poor contact may lead to failure.
3) BD module and top cover of PLC’s tightening torque is 0.3 ~ 0.6 N.m.
Warning:
Make sure to power off the PLC before mounting or removing the BD module and put the cover in
right place.
2.Special feature
1) LX3V-2ADV-BD module equips with 2 channels analog input. This module will be mounted in
the PLC.
2) The input voltage of LX3V-2ADV-BD module between -10 to 10V, and the digital value will be
saved in special system address, but the numerical relationship between input and output value
cannot be changed.

5.Wiring
Caution:
1) Don’t put the LX3V-2ADV-BD module near high-voltage power cable. Keep away the power
cable at least 100mm;
2) Do not solder any terminal with the others device;
3) Do not connect any unsuitable cable;
4) Please fix cable;
5) Do not connect any unit to the unused terminal;

6.Example
The input 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
Notes:
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.
The following program can set CH1 and CH2 into voltage input mode. After ADV conversion, values
of all channels are stored into D0 and D2.

6.2 Examples of Applications
Since the LX3V-2ADV-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.
Notes:
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 Input Mode
Under the voltage input mode, the 2ADV will convert the analog value -10V~10V into data output
-2000~2000. If the data range used in the application is 0-20000, then the range -2000~2000 must
be converted into 0-20000, as is shown in the following program examples. The data converted from
the analog values are stored in D8112 or D8113.
Since the data range is converted from -2000~2000 into 0-20000，therefore the resolution of the
analog input is no longer just 8uA.
Figure 6-1
If the data range used in D0 is (4000-20000), please refer to the following text：Figures used in the
user’s applications：D0=5×(D8112 or D8113)+10000.
We can give an example as follows based on the program of the above mentioned formula (under
