In the field of industrial automation, Mitsubishi Electric's programmable logic controllers (PLCs) are known for their reliability and efficiency. Among them, the Mitsubishi PLC Ethernet module FX3U-ENET-L is a key component for connecting to the network. It supports fixed buffer memory area communication, connection to MELSOFT, communication through MC series, email transmission, and other functions, providing a solution for the construction and operation of industrial control systems. Important support.

Functional features of FX3U-ENET-L

Fixed buffer memory area communication support: FX3U-ENET-L supports fixed buffer memory area communication, which makes data exchange more stable and reliable, and is suitable for application scenarios that require high communication stability.

Connect to MELSOFT: This module can easily connect to MELSOFT to achieve seamless integration with other Mitsubishi Electric software, providing users with comprehensive development and management functions.

Multi-channel communication: FX3U-ENET-L has 4 communication channels, but only two channels can use fixed buffering. Therefore, the master station PLC plus an Ethernet module can only communicate with one slave station using a fixed buffer.

Communication setting method between master and slave stations

Master station PLC parameter settings:

Set the IP address of the main station to

Make relevant settings in the main site.

Write the main station PLC program.

Slave PLC parameter settings:

Set the slave's IP address to

Make relevant settings in the slave station.

Write slave PLC program.

Remote maintenance and debugging

Through GX Works2 software, users can easily achieve remote maintenance and debugging of PLC programs. This enables engineers to monitor and manage PLC systems in real time at different locations, improving maintenance efficiency and system reliability.
