Description

Facilitating seamless data communication between EtherNet/IP-enabled control networks and Modbus serial networks, the ProSoft PLX31-EIP-MBS protocol converter operates as a standalone gateway. Designed to link Rockwell Automation PLCs, including ControlLogix and CompactLogix systems, to Modbus RTU/ASCII-compliant devices, this module acts as a bridge for legacy and modern system integration. It allows the integration of sensors, drives, and specialized instrumentation into high-level control architectures without requiring expensive network overhauls.

The gateway is engineered for harsh industrial environments, offering high electrical isolation on both the Ethernet and serial pathways to prevent damage from ground loops. Featuring a compact form factor for DIN rail installation, the gateway delivers reliable data routing with configurable read/write commands, mapping internal registry memory across protocols with minimum transmission latency.

Features

Dual-protocol mapping facilitates real-time data exchange between EtherNet/IP master/slave devices and Modbus RTU/ASCII networks.
Complete galvanic isolation on serial and Ethernet communication paths shields control equipment from electrical noise and voltage transients.
Integrated diagnostic LEDs provide real-time status indication for power, network connectivity, internal errors, and port traffic.
Flexible power input tolerances make the module suitable for diverse industrial power distribution standards.
Configuration is managed via user-friendly software utilities, allowing memory offset mapping and quick deployment.

Applications

Oil and gas production monitoring, connecting Modbus-based flow meters to EtherNet/IP RTU networks.
Water and wastewater plant automation for motor control center (MCC) integration.
Power generation and substation systems linking protective relays to central SCADA systems.
Factory automation environments standardizing fieldbus devices onto unified Ethernet backbones.

Installation Guidelines

Ensure the unit is mounted on a standard 35mm DIN rail within a dust-free and temperature-regulated control enclosure.
Always use shielded Ethernet (Category 5e or higher) and shielded twisted-pair serial cables to limit electromagnetic interference (EMI).
Connect the GND terminal directly to a clean, low-resistance functional earth ground bus bar.
Ensure there is adequate ventilation spacing of at least 25mm above and below the module during operation.

FAQ

What power input does the ProSoft PLX31-EIP-MBS require?

The gateway operates on a nominal 24 VDC power supply, but is compatible with a wider input range of 10 to 36 VDC.

Does the serial port on the PLX31-EIP-MBS feature isolation?

Yes, the serial port provides 2500 Vrms signal isolation utilizing RF modulation technology compliant with UL 1577 standards.
