Description
Product Description
The PLX31-EIP-MBS4 from ProSoft Technology is an industrial communication gateway engineered to exchange data between EtherNet/IP automation networks and multiple Modbus serial devices. The module belongs to the PLX31 series and provides four independently configurable serial channels for integrating legacy Modbus equipment into Rockwell Automation architectures.
This gateway is commonly deployed in applications where a single PLC must communicate with several isolated Modbus RTU or ASCII networks simultaneously. Its standalone DIN-rail design allows installation without occupying PLC rack space, making it suitable for both new automation systems and retrofit projects.
The module supports EtherNet/IP Scanner and Adapter functionality together with Modbus Master or Slave operation, allowing flexible protocol conversion in distributed control environments.

FAQ
How many Modbus devices can the PLX31-EIP-MBS4 support?
The number depends on network configuration, polling rate, and baud speed. The four serial ports allow multiple Modbus segments to operate simultaneously.
Can each serial port use different communication settings?
Yes. Each serial interface can be independently configured for RS-232 or RS-485 operation, baud rate, and Modbus mode.
Which PLC platforms are compatible with this gateway?
The module is commonly integrated with Rockwell Automation ControlLogix, CompactLogix, and Micro800 systems through EtherNet/IP communication.
Does the module require rack installation?
No. The gateway is a standalone DIN-rail device and operates independently from the PLC chassis.
