Prosoft PLX35-NB2 EtherNet/IP to Modbus RTU Gateway

This gateway bridges Modbus RTU devices into EtherNet/IP networks, streamlining communication while optimizing Ethernet bandwidth through simultaneous I/O connections. It’s particularly useful in environments where legacy devices need integration with modern control systems, such as factory automation or process control applications.

In real-world applications, this device shines when connecting legacy equipment like flow meters or motor controllers to EtherNet/IP networks. A plant engineer once shared how it simplified integration of older Modbus-based sensors into their Rockwell Automation system without requiring network overhauls. Our inventory includes Prosoft’s PLX35 series gateways, including variants like the PLX35-NB2 and complementary models for specialized protocols.

The PLX35-NB2’s embedded EDS Add-On Profile reduces configuration time, while the SD card slot enables quick firmware recovery during outages. Its four serial ports support daisy-chaining multiple Modbus devices, and the 4-character LED display provides plain-text diagnostics—no codebooks needed. Though it lacks explicit redundancy features, users report its stable performance in harsh industrial environments. Compatibility with both EtherNet/IP and Modbus RTU protocols makes it a versatile choice for bridging disparate systems without sacrificing data integrity.
