LX3V-2RS485-BD

The WECON LX3V-2RS485-BD is a communication expansion module (baseboard) for LX3V series PLCs that adds two additional RS485 communication ports. It enables Modbus RTU/ASCII, N:N networking, and protocol-free communication with third-party devices (e.g., printers, scanners). It is installed directly on the PLC.

Key Features and Description:

Communication Ports: Adds 2 * RS485 channels (labeled typically as COM2 and COM3, or simply as additional ports) to the PLC.

Protocols Supported: Supports Modbus RTU/ASCII, user-defined protocols, and N:N networking for high-speed data transmission.

Installation: It is a “BD” (Baseboard) module, designed to mount directly onto the main unit of the WECON PLC without consuming extra rack space.

Applications: Ideal for linking HMI, inverters, smart meters, or barcode readers using RS-485.

Compatibility: Designed for WECON LX3V Series PLCs.

Signal Type: Serial communication via RS485.

Technical Functions:

No-Protocol Transfer: Uses RS instructions to communicate with any serial device.

Proprietary Protocol: Supports 1:N data transmission, suitable for networking multiple devices.
