Product Profile

The ProSoft PLX31-EIP-MBS4 is a versatile EtherNet/IP to Modbus serial gateway that enables Rockwell Automation PLCs to communicate with up to four independent Modbus RTU/ASCII serial networks. It is designed for industrial applications that require integration of legacy serial devices such as power meters, drives, flow computers, and remote I/O into modern EtherNet/IP control systems.

With its compact DIN rail mountable enclosure and built-in web diagnostics, the PLX31-EIP-MBS4 provides a cost-effective solution for protocol conversion without the need for complex programming or additional middleware.

Technical Data

System Role

The PLX31-EIP-MBS4 functions as a protocol translator and data concentrator, allowing a single EtherNet/IP scanner to access multiple Modbus serial networks simultaneously. It handles data mapping, polling, and error management, significantly reducing the processing load on the PLC while providing transparent communication between the two protocols.

Compatibility

• Compatible with Rockwell Automation ControlLogix and CompactLogix platforms.
• Supports Modbus RTU and ASCII master/slave configurations.
• Works with a wide range of Modbus-enabled field devices from various manufacturers.
• Software configurable via ProSoft Configuration Builder.

Typical Applications

• Integration of power meters and energy monitoring devices into EtherNet/IP systems.
• Connecting legacy Modbus drives and soft starters to modern PLCs.
• Data acquisition from remote flow computers and analyzers.
• Building automation and HVAC control system integration.
