LX5V-4ADI-BD BD Module Manual
1 Installation
▪
Before installation, it must be ensured that the PLC host and the related device of the BD module terminal
wiring are powered off reliably. The shell is inserted into the BD module slot of PLC host, and then locked
with two standard screws for fixation.
▪
Two standard terminal heads are equipped with this BD module. After connecting the wiring, insert them
into its terminal. After confirming that the host, BD module, wiring, etc. are installed correctly, it can be
powered on for use.
▪
✎Note:
● The ADI input must not exceed the absolute maximum (-2mA/+ 30mA), otherwise the BD module will
be damaged.
● Please install the BD module firmly and fix it on PLC. Poor contact may lead to failure.
● Tightening torque for fixing BD module or PLC top cover is 0.3N.m to0.6N.m. Please tighten it firmly to
avoid malfunction.
●
You can only use a LX5V-4ADI-BD on the PLC main unit of LX5 series.
▪
Warning: Cut off the power before installing, removing or wiring the BD module to avoid electric shock or
product damage.

It flashes when communicating with PLC normally, and it is OFF when timeout.
Channel 1 lamp: Always on in range; Flashing outside the range of (4mA to
20mA); Off when the channel is closed.
Channel 2 lamp: Always on in range; Flashing outside the range of (4mA to
20mA); Off when the channel is closed.
Channel 3 lamp: Always on in range; Flashing outside the range of (4mA to
20mA); Off when the channel is closed.
Channel 4 lamp: Always on in range; Flashing outside the range of (4mA to
20mA); Off when the channel is closed.

PLC (slot number 1 or 2, the software will select slot 1 by default, and right-click to move down to slot ③ After adding the BD module to the slot, double-click or right-click to select configuration parameters to enter LX5V-4ADI-BD configuration parameters interface, as shown in the following figure. Configure related parameters on this interface. - Page 5 Note: This function is only supported in the following versions of host computer, slave computer and BD module:...
- Page 6 (1) Supported host computer versions: Wecon PLC Editor2 2.1.204 and above, as shown in the following figure: (2) Supported slave computer versions: 2.051 and above, as shown in the following figure: (3) Supported BD module version number: 1013 and above, as shown in the following figure:...
- Page 7 The parameter configuration interface is as below: 1、Module setting: Set response time (The response time is the interval time between PLC acquisition of BD module data. Range: 0.1ms to 3276.7ms). 2、ADI configuration: Check enable channel to set whether to enable the current BD module channel. The conversion mode is set to ADI conversion mode by default, and the measurement range is 4mA~20mA (0~2000).
- Page 8 2000 1970 Suppose the gain is a, and the offset is b, then 1.030928 -30.92784 Solve and get The calibration can be completed by setting the corresponding gain offset to the current channel.
- Page 9 3、Set I/O mapping. The channels are mapped to R device according to the current number of BD module channels by default. As shown in the following figure, BD module CH1 to CH4 is mapped to device R0 to R3. 4、After the above configuration is completed, check the program, download the configuration to PLC, and STOP→RUN configuration takes effect.
