ProSoft PLX31-EIP-MBS EtherNet/IP Gateway Module

Product Description

The PLX31-EIP-MBS communication module is an industrial protocol gateway developed by ProSoft Technology for integrating EtherNet/IP controllers with Modbus serial field devices. It enables reliable bidirectional communication between Rockwell Automation PLC platforms and Modbus RTU or ASCII networks in mixed-protocol automation environments.

Designed as a standalone DIN-rail device, the module supports flexible deployment in control cabinets, SCADA systems, OEM machinery, and retrofit modernization projects. The gateway combines EtherNet/IP Scanner and Adapter functionality with configurable Modbus Master or Slave operation, simplifying communication between modern Ethernet architectures and legacy serial equipment.

The compact industrial housing, extended operating temperature range, and diagnostic capabilities make the PLX31-EIP-MBS suitable for continuous operation in demanding industrial facilities.
